1. Preliminary Remarks

1.1 Information about liability and warranty CAUTION! All information and references concerning operation and maintenance of the equipment are based on our experience and are made to the best of our knowledge. In this Manual standard modules are described. Minor variations are either not specifically considered or dealt with separately in an annex. Maintenance and service instructions are not part of this Manual. Maintenance is dealt with in the maintenance description provided after previous training. The maintenance protocol permits docu-mentation. The technical information and data stated in this Manual are refer to the state of technology at the time this Manual was printed. We reserve the right to make technical modifications when required for developing purposes without previous notice and without respective change of this Manual. Thus no claim can be derived from the details and descriptions found herein. The text and graphic representation do not at any rate comply with the actual scope of delivery or spare parts order. All drawings and graphics are not on a 1:1 scale. We do not accept any liability for damage and operating trouble occurred due to operating errors, disregard this Manual or im-proper repair work. The Woodward original spare parts and Woodward accessories are chosen, designed and tested especially for Woodward switchboards. We strongly recommend to buy spare parts and accesso-ries from Woodward only. We would like to stress that spare parts and accessories not delivered by Woodward have to be accepted by us first before they are used. We have to point out that through installation and the use of other than Woodward products, or products not accepted by Woodward, the constructive properties of the switchboard might be affected and the safety for operators, sys-tem or other tangible material be impaired. Woodward does not undertake any liability for damage resulting from the use of spare parts or accessories not accepted by our firm. Unauthorized re-construction work and changes at the switchboards are not permitted for safety reasons and any resulting damage is exempted from Woodward’s liability. The warranty and standard liability conditions of the Woodward General Business Terms and Con-ditions are not changed or extended by the before stated.



1.2 Important information

1.2.1 Specific tips how to use this Manual In this Manual three different indications and symbols are used in order to put emphasis on impor-tant information: CAUTION! this draws attention to information which have to be adhered to in order to protect the user from harm. IMPORTANT! this draws attention to information which have to be adhered to in order to advert any damage from the component.

This refers to general or additional information on a specific subject.

1.2.2 Marking of switchboard components

This symbol is fixed to components where information about possible hazards have to be gathered from the operating instructions.

This symbol can be found in those areas of the switchboard where danger to life is imminent due to high voltages. In this area repairs must only be done by commissioning or maintenance personnel trained by Woodward and by observing all locally relevant standards and regulations. To all other personnel access to this part of the switchboard is not permitted.

This symbol can be found in areas of the switchboard where an electrostatic discharge at electronic devices is possible. The electronic components of the control computer can be damaged by elec-trostatic discharges. Electronic components or switched paths must not be touched! When working on open electronic components a reliably functioning ESD-wrist has to be worn!



1.2.3 Information on commissioning Before starting the commissioning please read the following carefully and make sure your have properly understood all of it. Commissioning of the CONCYCLE® Wind Inverters is only allowed to be done by Woodward per-sonnel or by electricians, trained by Woodward and who are authorized for this kind of work at the time the commissioning takes place. Operation of the inverter within the Wind Power Plant (WPP) has to be stipulated and safeguarded by the manufacturer of the WPP. The maintenance work defined by Woodward has to be carried out for reliable functioning of the equipment as well as with regard to warranty claims. The dates stated by Woodward ought to be kept and the actual maintenance work has to be done by skilled electricians, authorized by Woodward. Maintenance training, maintenance instructions and protocols can be obtained after successful training from our Service Department. It is of great importance that the person carrying out the electrical commissioning has undergone a proper training with regard to the functioning of all oper-ating elements and has also the required understanding. According to EN 50 110-1, DIN VDE 0105-100 and BGV A3 it must be secured that the switch-board is dead prior to start of the work and has to remain in this state until the work has been fi-nished completely. Before commissioning the company carrying out the work has to make absolutely sure that the electrical facilities comply with all requirements specified by IEC 60364-6-61 and that all tests stipu-lated in these standards were performed satisfactorily. Commissioning of the CONCYCLE® Inverter has to be done strictly in line with the related commis-sioning protocol (see annex). The protocol testifying that the CONCYCLE® Wind was duly handed-over has to be sent to the Woodward Service Department within the contractual stipulated time. In case the respective date has not been met, the contract agreements between the customer and Woodward apply. All information/instructions stated in this Manual or on the product itself (Woodward switchboard) ought to be strictly observed. IMPORTANT! Dependent on their protection class, frequency inverters may have bare live parts or also rotating parts and sometimes surfaces become hot during operation. Thus after operation sufficient cooling down times have to be allowed for heat-storing components, such as large chokes, for instant. CAUTION! There is the risk of severe personal injury and/or damage of material if protective covers are re-moved without permission, if the inverter system is used in an improper way or if the installation or operation is wrong or faulty.



Always be prepared for fire or accidents! Make sure that a first-aid kit and fire extinguisher are always within easy reach of electrical installa-tions. Operators have to be versed in and well-trained for handling all of the safety devices.

Figure 1.1: How to behave in case of fire or accidents CAUTION! In case of fire only CO2- extinguisher are allowed to be used! (Volume of the room on fire has to be taken into account because e.g. the gondola has only a small usable room volume). When powder extinguishers are used this results in irreparable soiling of the switchboard! The following five safety rules have to be strictly followed!

Figure 1.2: 5 safety rules IMPORTANT! Should any work become necessary during commissioning where the switchboard has to be open then it must be absolutely ensured that the Wind Power Plant is switched off. At the CMW, the operating unit of the Woodward switchboard, the existing measuring value of the intermediate circuit voltage can be read out in menu “Measuring Values”! As soon as this voltage has dropped under 20 Vdc, the system can be disconnected from the mains! Only if this has be done, the switchboard is safe to be opened! (Attend the 5 Safety Rules)

How to behave in case of fireKeep Calm !

1. Report the fire: Phone the local emergency no.- Give your name- WHAT has happened?- HOW many are affected?- Name the location- Wait for questions to be asked

2. Strive for safety: - Rescue people in danger- Shut doors- Follow the marked escape route- Do never use a lift- Observe all instructions

3. Try to extinguish the fire: - Use the fire extinguisher

How to behave in case of accidendsKeep Calm !

1. Report the accident: Phone the local emergency no.- Give your name- WHAT has happened?- HOW many are affected?- Name the location- Wait for questions to be asked

2. First aid: - Secure the accident location- See to the injured ones- Observe all instructions

3. Further steps: - Direct the ambulance or fire- Brigade to the location- Urge onlookers to move away

5 Safety Rules Before starting any work: • Isolate power • Secure against re-connection • Check whether the equipment is dead • Earth and short-circuit the equipment • Any adjacent live parts to be covered or • to be blocked off



People who cannot be considered skilled electricians because their training or employment history does not comply with the requirements of the German Trade Association are not allowed to carry out electrical measurements. It has to be stressed that such employees are only allowed to do re-pair works when supervised by a skilled electrician and the switchboard is dead! Commissioning personnel who have acquired their skill to work at electrical systems or electrical equipment abroad, have to adhere to the specific provisions of law which apply in the respective country! Only components accepted by Woodward are to be used as spare parts (see related Parts List of the Woodward switchboard)! Therefore we strongly recommend to plan the procurement of spare parts well in advance. Information on spare parts can be obtained from the Woodward-Service De-partment. The manufacturer does not undertake any liability for consequential damage resulting from impro-per or negligent installation of components, wrong adjustment of parameters and wrong operation of the CONCYCLE® Inverter System.

1.2.4 Information to the Manual Without the expressed and written acceptance of the manufacturer no part stated in this Manual is allowed to be reproduced or passed on to others, neither on electronic means nor mechanically (i.e. photo-copying process, recording or by using any system for storing or retrieving of informa-tion). The contents of this Manual refers to the software version of the system stated in the text at the time of printing. The manufacturer reserves the right for alterations in line with the relevant technic-al further development of the system without notice. This Manual is part of the switchboard delivery scope. When the switchboard is passed on to a third party (removal to another location, selling to another firm or the like), this Manual has to be handed-over as well.



2. Transportation

2.1 Safety measures for transportation Care has to be taken that the frequency inverters are not exposed to inadmissible environmental conditions and strain, such as dampness, dust and vibrations. It is also essential that during trans-portation and when handling no components are being bent and/or that spacing of the insulation is not altered. Electronic components and their contacts must not be touched. Information on the permissible am-bient conditions can be found below in chapter 9. IMPORTANT! Frequency inverters include components which are endangered by electrostatics and they can eas-ily be damaged or pre-damaged when handled in an improper way. Hence the following points have to be care-fully observed: • Electrical components must not be mechanically damaged or broken (when capacitors be-

come defective the escaping dielectric can be a health hazard!). • Load handling attachment must only be applied at the point intended for this purpose. For

instance, transport brackets have to be secured so that they cannot slide off. Transport frames, suitable for the equipment, have to be mounted and be used if specified.

• Ropes, chains or other load handling attachment have to be provided with safety hooks. • Any ropes used must be 100% intact, they must not be torn or chafed anywhere. • Ropes and chains must not be knotted. • Ropes and chains must not touch any sharp edges. • Pulling facilities of individual system parts must not be used for the transport of other parts. • Only lifting facilities, ropes and chains of sufficient strength must be used. • Loads must never be lifted over people! • Switchboards in general should only be transported in a vertical position. Tilting of the

switchboard or transport in a tilted position is only allowed if this is expressively permitted for an individual case.

The specific ambient conditions to be observed for transportation can be found below in

chapter 9. Switchboard specific instructions with regard to lifting, crane and transportation can be

found in the data sheet.

2.2 Delivery The individual sections of the system and the accessories are dispatched in packages suitable for the respective means of transportation. Woodward always tries to use an environmental-friendly packing which in general can be used several times. The packing remains with the customer, un-less an agreement was reached with Woodward that the package can be returned. The packing material must be disposed of in an ecologically beneficial manner and has to be in compliance with the existing disposal regulations. If necessary disposal of the packing material has to be delegated to a waste disposal firm. If you need any more details please contact the Woodward Service Department.



IMPORTANT! Dispatch and transport guides in form of internationally accepted pictograms are provided on the consignments. It is very important that these guides are strictly followed throughout all phases of transportation and storage. The markings and pictograms used are shown below together with the relevant explanations. A= Top K= Solid package B= Fragil goods L= Permitted temperature range C= Keep dry! M= Do not apply a fork lift truck here D= To be protected against heat E= Hooks are not be used F= Centre of gravity G= Chains etc. to be placed here H= Do not use a sackbarrow I = To be clamped in direction of the arrows J= Permitted stack load

2.3 Transport at Inspection The terms of the transport insurance are stipulated in the Delivery Terms. It is recommended to check the entire delivery for possible transport damage and for its complete-ness immediately after receipt. IMPORTANT! By disregarding the following instructions the liability of the Transport Insurance Company may not apply in the event of damage or loss. In the case of suspected damage, the receipt should be acknowledged with reservation only (e.g. on the freight document) by stating the probable damage. Damage claims on a third party have to be indemnified! Transport companies or other carriers, shipping companies, storage firms, customs and harbour authorities have to be requested to attend a joint damage survey. They have to be held liable in writing and the damage must be detailed: • before acceptance of the goods when the damage can immediately be identified • and damage which cannot be identified from the outside has to be notified directly after

discovery The times to submit complaints have to be found out and must be met.

2.4 Inspection of Damage It has to be secured that the damage occurred does not change for the worse and that further damage is prevented. The surveyor stated in the insurance documents has to be consulted without delay so he can come and ascertain the damage as well as give advice as to minimize the damage and how to put for-ward damage claims on third parties. The state of the consignment and its package must not be changed until the surveyor give his O.K., unless it is necessary for the purpose of minimizing the damage or preventing that additional dam-age is done. The insurance company has to be notified of the insurance case at once. In order to speed-up set-tlement of the claim, the complete claim documents should be submitted to the insurance company (make sure you are well aware of expiration of possible exclusion deadlines and/or limitation pe-riods).

2.5 Unloading The safety standards and the applying safety regulations have to be observed! Only skilled people familiar with the lifting gear and the perhaps necessary auxiliary devices must be entrusted with the unloading procedure. Details on the weight can be found on the respective transport label provided at each consignment and the forwarding documents. When unloading the functional separate lifting accessories should be used. IMPORTANT! The permitted lifting weight of the separate lifting accessories and the lifting gear (crane, forklift truck etc.) has to be observed. The loading instructions shown on the transport markings have to be followed. When loading or unloading any switchboard sections without packing they have to be fastened at the transport eyes provided for this purpose.



2.6 Rotor short-circuit supervising The CONCYCLE® Wind Converter/Inverter-System is fit with a rotor short-circuit supervising, which is permanent active during the excitation-mode. ATTENTION! The rotor short-circuit supervising is not activated in converter/inverter-systems where the conver-ter is not directly connected to the generator stator. The rotor short-circuit is detected as follows:

• The dc-link voltage is permanent supervised by the line-side converters control-computer CSC-SU.

In case of a sudden death of the dc-link voltage during excitation, the error-bit “commis-sioning missing” is put in to a high state. The commissioning counters will be put down to the step “encoder balancing” afterwards.

Actions

• Eliminate reason for the rotor short-circuit.

As the commissioning-counter is put back, the operator has to run a new encoder-balancing, be-ginning with the rough balancing (Chapter 6.3.3).

Furthermore all commissioning-steps which follow on the encoder-balancing have to be run, also.



3. Storage Under no circumstances the switchboard or parts of the switchboard should be stored in the open. The storage rooms have to be well ventilated and be dry. Until installation the consignments have to be stored as indicated on the transport markings and in line with the permitted ambient conditions. Packed switchboard sections and accessories must not be unpacked when stored for a longer pe-riod. For storage the following regulations apply in general:

• The storage room the switchboard is stored in has to be kept dry and frost-free. It also has to be ensured that the floor of the storage room does not get wet.

• The consignments must not be stored in the open.

• A sufficient quantity of dehumidifier has to be put into the switchboard panels. Proper func-

tioning of the dehumidifier has to be checked regularly until commissioning.

• The switchboard is to be protected against solar radiation.

• All ventilating openings at the sidewalls and the roof must be protected against wetness and dust.

• Mechanical vibrations and damage must be avoided.

• The storage room must be properly air-conditioned because when the switchboard is not

connected, the automatic switchboard heating and ventilating facilities are not operable.

• Exposure to dew has also to be prevented when stored. If this cannot be completely ex-cluded, remedial measures have to be discussed with the manufacturer. Occasional dew deposits during storage must also be prevented.

The specific ambient conditions to be observed for storage can be found below chapter 9. In case the switchboard is stored over a longer period of time, preservative measures in agreement with Woodward have to be taken or the existing agents to be renewed. These potential preserva-tive measures have to be discussed with Woodward prior to dispatch of the switchboard. IMPORTANT! Packed switchboard sections and accessories must not be unpacked even when stored for a longer period. An exception is the inverter power part and the static UPS module. For this equip-ment the following instructions apply.



3.1 Storage of the converter power part The intermediate circuits of the power parts are equipped with high-voltage electrolytic capacitors. Even during disconnection (e.g. when stored or during longer lasting interruptions) electrochemical processes proceed inside the capacitors. During a long storage the dielectric material (consisting of an oxide layer of about 1µ ) in the capa-citors of the intermediate circuit decomposes, a so called loss of the capacitor forming. Thus this can lead to an increased leakage current when the capacitor voltage is reconnected and may cause damage or failure of the capacitors, depending on the length of time the equipment was dead as well as the kind and intensity of the voltage. Maximum storage time (only by electrolytic capacitor) Storage of a disconnected equipment without re-forming procedure is limited to one year only (ca-pacitors with rated voltages in the range of 350 V > UNOM >/= 500 V) ; thereafter the capacitors have to be re-formed according to the instructions of the manufacturer. For complete systems this one-year period start with the test date (as stated on the type label of the switchboard) and for IGBT spare modules with the date of delivery. Unless agreed otherwise, the check of this deadline and observance of the re-forming cycles are the responsibility of the owner of the equipment. When a re-forming procedure is due please contact the Woodward Service Department. After a longer storage period > 1 year, interim capacitors must undergo a formation procedure, otherwise they can be destroyed after a storage period > 1 year when rated voltage is applied. The formation procedure is described in the maintenance manual.

“Formation of the capacitors of the intermediate circuit” can be found in the data sheet.

3.2 Storage of the Static UPS Module The terms for storage and maintenance can be found in the technical description of the static UPS module.



4. Requirements on the Mounting Location IMPORTANT! The following requirements on the room where the switchboard will be set-up have to be consi-dered already in the planning stage, they can be found in the technical data sheet. The weight of the switchboard parts have to be taken into duly consideration!

4.1 Space requirements

Detailed information on the space requirements at the mounting location can be found in the data sheet of the switchboard.

Especially the space required in the following for supply and dissipation of the cooling air as well as for mounting and maintenance work have carefully to be considered.

4.2 Installation requirements on the switchboard room There must be sufficient space to ensure free access to the switchboard. Setting up and operation of the switchboard and other equipment has to be in line with the instruc-tion stated in the related technical documentation. The minimum room height is subject to the height of the switchboard and at least 1 m has to be al-lowed for the dissipation of hot air. When the switchboard is set up the minimum clearances to walls and other equipment/machines etc. have to be in compliance with the constructional drawings, so that switchboard doors can be opened without problems. The stops of the switchboard doors have to be coordinated with the al-lowed flight direction of the room and the doors have to open outwardly. Passages and door openings must be wide enough for the equipment to be brought into the room (if they are not, the respective actions have to be taken, e.g. by widen the openings). The outside dimensions of the equipment is stated in the technical data sheet. The weight of the switchboards and its related modules have to be carefully considered. Confusion concerning the floor strength as well as where certain floor or ceiling constructions are concerned, the firm setting up the equipment has to clarify these matters. Before the equipment is brought in, the floor must be fully completed. The floor is expected to be soundness and level. When laying the floor in the switchboard room and the foundation the regula-tions according to DIN 43661 apply. In some cases raised floors might need to be enforced addi-tionally.



4.3 Ambient conditions, temperature and cooling air require-ment The ambient temperature and the necessary cooling requirement stated in accordance with the specification, Woodward-deviation list and in chapter 9 must be adhered. For details please see the technical data sheet. Exposure of the equipment to dew is to prevented. An air conditioning system or a device for cool-ing down the circulating air should be provided if this is necessary to guarantee the ambient tem-peratures al-lowed for operating the equipment. Care must be taken that the ventilating slots are always free and clean. Further conditions to be considered for a reliable operation are: Climatic, biologic and mechanic ambient conditions as well as those concerning chemical or me-chanically active substances.

The operational ambient conditions applying for the location can be found in the data sheet.



5. Electrical Connections

For detailed information on the cable entry direction and connection points please see the switchboard data sheet.

IMPORTANT! According to the VDE Regulations and BGV A3 (formerly BGV A2) and the internationally applying regulations, all connection jobs have to be done and protective measures to be taken by authorized skilled electricians only.

5.1 Cable entries Cable entries for electrical equipment are always provided as specified by the customer. The cable is put into the equipment through sealed openings (PE bolting or flexible profile sealing material). The covers of the cable entries can be unscrewed and are of non-magnetic material. IMPORTANT! When mounting and when the cable is inserted, it has to be ensured that the used sealing compo-nents are installed in a skilled and effective manner. The cables have to be fastened properly at the cable-train relief clamp in compliance with the respective standards and with the installation ma-terial provided.

5.2 Connections of cables and conductors All cable connection points are clearly labelled and marked in accordance with the switchboard ca-ble plans. If not marked differently, the phase sequence of multiple-wire connections is always clockwise. For the mains terminals the cable connections are marked with L1 - L2 - L3, for the ge-nerator stator terminals with U - V - W and for the generator rotor terminals with K - L - M. IMPORTANT! When electrical cable is connected and if not stated differently, the core cable ends used have al-ways to be suitable for the cable cross-section, which also applies for the squeezing appliances. The connection screws must be tightened with the correct torsional force. IMPORTANT! When control or signal cables are connected or applied it is essential to use core sleeves suitable for the cable cross section and also the right pressing tool punch. Checking the tightness of the in-dividual cores is part of the installation work. (as specified by the manufacturer).



5.3 Earthing connections IMPORTANT! It must be absolutely ensured that all PE conductors are connected to the PE bus of the equipment and that any additional earthing points are properly connected with the earthing system of the equipment. An effective earth connection of the PE conductors at both ends and screening of the rotor cable is very important. In order to avoid loop current attention must be paid that all other components (stator, rotor etc.) are star connected to the main PE bus of the CONCYCLE® inverter switchboard.

5.4 Rating of the conductor cross sections Different factors have to be considered for rating the cross sections of the cable to be connected, for instance, temperature, length, frequency rate etc. Normally this task is done by the manufactur-er of the Wind Power Plant in accordance with the locally applying regulations. The cross section rating is stipulated in the specification and is subject to acceptance when the WPP is type tested.

5.5 Fuses IMPORTANT! The fuses are selected according to different factors, such as power, peak load, voltage drop etc. and hence the values stated by Woodward are only to be understood as recommended values. The final rating of the fuses has to be checked for the specific installation and be done in com-pliance with the local regulations. The CONCYCLE® Wind Modules are built for certain values of the rated apparent power. The pow-er data is based on continuous duty.

On this subject Woodward offers supporting information and advice. Project related details can be found on the flyleaf of the circuit diagram.

IMPORTANT! Short-term inadmissible over-currents during interruptions may damage the fuses and can change the trip characteristic. After important interruptions we suggest to replace all fuses involved. When fuses are replaced it is important to use only fuse types which are specified in the Parts List and thus are accepted for the equipment by Woodward. Never use any others.



6. Electrical Commissioning IMPORTANT! For electrical commissioning the commissioning protocol has strictly to be followed. That protocol is attached to the switchboard plan provided.

6.1 General outline of the proceeding The commissioning procedure is divided into 2 parts: Part 1 To make the electrical connections to the Woodward Inverter System and Wind Power

Plant. Part 2 Electrical commissioning of the Inverter System by means of the operating unit CMW.

6.2 CONCYCLE® Monitor “Wind” (CMW)

Figure 6.2: CMW The inverter system is operated and set into operation by the CMW. Operational conditions and fault messages are shown in the display. Additionally it is possible to log-in into the CMW by means of a PC or laptop by using a RS-232 in-terface and a zero modem cable. The Woodward software “Customer Tool” enables to read-out operational data and also to change parameters during commissioning.

6.2.1 Operational modes of the CMW Besides the keyboard and the display, the CMW is provided with a key switch by which the inverter system can be switched into 3 different operational modes. These operational modes are: Auto: The inverter system is automatically controlled. In this mode access to the CMW is

possible for reading purposes only. The inverter system communicates with the higher-level Wind Power Plant control either via a connected bus system or via 4 interfaces 20 mA.

Manual: The inverter system can manually be exited and then switched to mains parallel

operation. This operational mode is also used for electrical commissioning Service: All signals of the higher-level WPP control are ignored by the inverter control when

this mode is selected and it is used to carry out service jobs. There is no risk of an unintentional start and excitation of the inverter system.

6.2.3 Function of the keyboard elements on the CMW Info-Key

This key is for changing from the submenu to the info page. Change to the info page during the commissioning procedure is not possible. Page selection key

The user menu of the CMW consists of several submenus (see the following flow chart about the menu arrangement). By these page selection keys the submenus are called up or left. It is possible to skip commissioning steps which are already checked, if the commissioning menu is manually called up. Skipping of individual steps is not possible during the initial commissioning work. Navigating keys

Subject to the customer specification the following parameters can be selected and changed when in menu „Commissioning“ or „Service“:

• Power speed characteristic • Torque default setting • Power factor default setting • Position encoder Offset • Adjustment of the four interfaces 20mA

For changing the parameters the placeholders for value assignment are selected by the navigation keys <Up> and <Down>. The navigation keys for <Left> and <Right> are used for selecting the decimal point position for the numerical values. Plus/Minus keys

These keys are used for changing the value assignment via the CMW. With key <Plus> the parameter value is increased, with key <Minus> it is decreased. For logical parameters the key <Minus> is assigned to the logical proposition „NO“ , the key <Plus> to the logical proposition „YES“. This is relevant, for instance, for changing the active status (see chapter “Change into the Active Status” in chapter “Sequence of the Electrical Commissioning”).



Enter key

With the »ENTER« key inputs or menu selections are acknowledged at the CMW. Reset key

With this key fault messages are reset. And when in the commissioning mode it is possible to negate value assignments as long as they were not acknowledged by <Enter>. (Here the key switch must be in position “Manual” and the Ac-tive Status be selected. „ON“/„OFF“ keys

In key switch position “Manual” these keys can be used to excite or de-excite the inverter during and after commissioning. „I“–„O“ keys

In operational mode „Manual“ the generator CB can be connected or opened with these keys. Additionally these keys are used to activate different relays for test purposes during commission-ing.

6.3 Sequence of the electrical commissioning IMPORTANT! The individual commissioning steps have to be completed one after the other, none of them can be left out. Dependent on the specification, the test steps listed below have to be followed during the initial commissioning

• Run up of the system: The Controller System (CSC) of the inverter is booting.

• Upload the actual Generator Parameter-set: The generators type can be taken from the rating plate. The parameter-file with the file-extension *.cpw is distributed by the Wood-ward-Service and has to be uploaded with the parawriter-tool (see chapter 7, customer tool).

• Check of the digital I/Os: During this test step the wiring of the input and output signals is

tested and the relay assignment between inverter control and the higher-level WPP control is checked.

• Adjustment of the generator position encoder: This task is carried out in two steps:

1. Coarse adjustment 2. Fine adjustment

The object is to have for the CONCYCLE® control a default setting of a defined rotor posi-tion angle of 90° via the position encoder.

• Check of the generator current transformers: In order to check the correct phase sequence

of the generator current measurement, an increased current is shortly provided by the in-verter in single operation.

• Check of mains synchronism: During this test the generator voltage is automatically syn-

chronized with the mains without closing the generator CB. If the LV main distribution is not supplied by Woodward, the zero current has to be meas-ured via the opened generator CB contacts during the test for mains synchronism. Finally it is changed to operational mode “Mains Parallel”.

• Final steps: From mains parallel operation the system is slowed down and then stopped.

Commissioning work is being completed.

During commissioning each single step has to be acknowledged with at the CMW. After each commissioning step, the program queries the control computer for the test sta-tus. If a commissioning step cannot be completed thoroughly, it is regard as not tested.



6.3.1 Activation of the commissioning mode at the CMW IMPORTANT! Prior to switching on the mains voltage all covers and panel doors must be shut. As soon as the operating voltage is available, the software for regulating and controlling is loaded into the working store by the control computers (CSCs). After the boot process is completed, the commissioning engineer is requested by the CMW to put the key switch into position “Manual”.

Figure 6.5: Screenshot Commissioning "Upload the correct set of generator-parameters before pressing the »Enter«-key." By pressing the key it is changed into the commissioning mode:

Figure 6.6: Screenshot Commissioning II The commissioning menu is divided into several subitems which are shown on the CMW display. By pressing the page selecting key item 2 of the commissioning menu is called up. At the bottom of the display there is a black bar. On this bar the test steps to be attended to next is displayed.

6.3.2 Check of the digital I/O and system messages

6.3.2.1 Digital inputs During this test the following contacts are queried by the control computer one after the other:

• WTC status (WTC = Wind Turbine Controller), • Excitation release, • Load request, • Reset fault • Emergency Off

IMPORTANT! Dependent on the specification the function of the respective inputs may differ.

Figure 6.8: Screenshot Digital I/O By pressing the page selecting key the individual test steps are called up, starting with sub-item „WTC Status“. When communicating with the CMW, the commissioning engineer is requested to switch through a 24V signal from the terminal of the respective contact in the WPP switchboard to the input terminal of the CSC-HU in the Woodward switchboard. The existing signal level is shown in the display.

Figure 6.9: Screenshot Excitation release The signal level at the chosen PLC input of the control computer is queried three times in succes-sion, starting with 0V. If both signal levels are equal at 0V and 24V, the test result is considered positive. The successful test has to be acknowledged by the key. The status of the individ-ual tests is shown in the CMW display either with “Not tested” or “Tested” The relevant terminal marking is additionally shown in the display of the CSC-HU controller.

IMPORTANT! It is not sufficient to switch the 24V DC- signal from one terminal in the Woodward switchboard to the PLC input terminal of the CSC-HU because this test procedure would not cover the entire con-duction path. This would not be in line with a reliable commissioning test. For testing the EMERGENCY OFF signals, this switch has to be activated at the Woodward switchboard as well as at the WPP switchboard. This way the correct connection between the Woodward switchboard and the WPP control board can be checked. IMPORTANT! Because of the slave function the CONCYCLE� Wind Inverter has within the WPP, it is not possi-ble to realize voltage-free from the mains by the EMERGENCY OFF button. Within a very short time the generator voltage is de-excited! The intermediate circuit needs > 8min. for discharge un-der protection low voltage.

6.3.2.2 External relay connection The purpose of this test is to identify any wiring faults of the control wire on the customer-side ter-minal strip. Here the commissioning engineer is assisted by relevant information shown on the CMW display. In succession each of the relays is displayed incl. name and marking of the allocated CSC contacts.

In systems which communicate with the WPP control via a CANopen-Bus or another communication interface, the wiring of external relays and their allocation is not checked.

Figure 6.10: Screenshot Digital Output The following relays are queried in succession:

• Working range • CSC status • Warning • Shut-down • Ready for connection • Inverter ready for operation • Over-speed

Dependent on the customer specification further relay outputs will be queried additionally.

By bridging the relay outputs (only with 24 V potential) with a measuring line it will be checked, whether there is any sparking at the relevant output terminals of the CSC-HU.

6.3.2.4 Specific handling of system messages

Figure 6.14: Screenshot External Customer Contact In order to check the correct wiring to the WPP control, the contacts on the CB terminal strip are to be bridged for this test. Activation of the related relay in the Woodward switchboard has to be checked. IMPORTANT! The terminal assignment differs according to the related specification. Hence the applying wiring diagram has to be compared when testing. The following contacts have to be checked:

• „Generator CB Tripped“ • „Generator CB On“ • „Mains Failure“

A mains failure has to be simulated via the mains de-coupling relay (see below). IMPORTANT! If the circuit breaker should not trip during the test then the control wire between the trip relay and CB has to be disconnected. After the test the connection has to be reconnected! The call for the test routine by the mains supervision relay leads to a fault signal at the CMW because the related supervision contact drops off. This is looped into the chain of shut-down faults (see related wiring diagram). Mains failure simulation by means of mains de-coupling relay, type XRW1-4 (only if it is an compo-nent from the converter) For the mains failure simulation the following key combination has to be pressed on the XRW1: 3x <Trip>; 4x <+>; 1x <Trip> Now the mains de-coupling relay passes through a self-test and activates all internal relays in suc-cession.

The following fault messages are displayed on the CMW during the mains failure test:

• „Mains-failure“ • „Ringline-shut-down“

These messages can be called at the CMW by pressing the key and have to be acknowl-edged by the key.

For acknowledging and resetting of the relays, the key <Select/Reset> on the mains de- coupling relay has to be kept pressed until the message „|SEG“ is displayed. For more details please see the technical relay description.

6.3.2.5 Check of the mains voltage at the CSC

Figure 6.15: Screenshot Testing Mains Voltage At the CSC-HU Controller (Terminal X3:17-24) the mains voltage can be measured. It has to be checked that the related protection devices and their alarm contacts (fuse with alarm contact or motor protection switch) are switched on. The mains voltage value is displayed on the CMW as well. If the commissioning engineer has failed to acknowledge the fault messages of the previous test, the CSC input “Mains Failure” is logically on 1 and so the following fault messages have to be ac-knowledged first:

• „Mains-failure“ • „Ringline shut-down“

Thereafter the next test can be called.

6.3.3 Calibration of the position encoder IMPORTANT! The inverter system is completely put into operation. All panel doors and covers have to be shut. The WPP has to be in trouble-free operational conditions when the position encoder is adjusted. The adjustment procedure for the position encoder is divided into two steps:

1. Coarse balance: The generator angle is automatically set to a range between 80° and 100° System with “LSC connected to grid” directly between 88° and 92°

2. Fine adjustment:

The generator angle is manually set to 90° with an accepted tolerance of ± 1° Commissioning of the speed window: The rotor speed should be in the range of the synchronous speed, but at least in the region of the inverter system excitation.

The synchronous speed is conditional on the number of generator poles. It has to be ensured that the following PLC inputs are activated at the CSC-HU:

• WTC status • Mains failure • Shut-down fault • Warning fault • Emergency Off

Adjustment of the position encoder cannot be continued if these inputs are not activated. An acti-vated PLC input is displayed as ticks on the CMW accordingly.

Figure 6.16: Calibration of the position encoder When the key is pressed all active signal levels are acknowledged. The information that the WPP is to be started appears now in the CMW display.

6.3.3.1 Coarse balance IMPORTANT! The WPP has to be accelerated up to the value shown in the speed window. As long as the speed range has not been reached, the message “System Not Within the Speed Window” is displayed on the CMW. This message automatically disappears after the necessary speed has been reached. Prior to starting the coarse balance procedure, the inverter at the generator side is to be excited by

pressing the key. During this process the generator voltage is being checked for keeping with-in a certain tolerance range. The inverter at the mains side is not in operation at first.

Figure 6.18: Screenshot Coarse Balance For starting the coarse adjustment press key . The generator angle is brought automatically to the rated value of 90° by the inverter control. Change of the generator angle by variation of the position en-coder offset can be observed on the CMW display. During the coarse adjustment process the following system quantities are monitored additionally:

• Rotating field, stator • Rotating field, rotor • Generator voltage, • Input voltage of the voltage inverter • Intermediate circuit voltage.

The coarse balance procedure is automatically stopped, when the generator angle has been ap-proximated to the rated value within a tolerance of ± 10°. The adjustment procedure can be acknowledged and stopped by pressing the key.

If the value of the position encoder offset is increased, the generator angle value is re duced. If the position encoder offset is reduced, the generator angle value is increased. The same applies for the fine adjustment.

Figure 6.19: Screenshot Shaft Angle Encoder Balance The actual value of the generator angle is shown within the „Pre. shaf angle encoder balance” menu in the CMW display (meas). By pressing keys or the commissioning engineer has now to change the position encoder offset and to activate this new value for the control by pressing key . By repeatedly adjusting the position encoder offset, the generator angle is to be set to 90° ±1°.

6.3.3.3 Check of the generator CTs (not “LSC connected to grid”) During this test the following is checked:

• Function, • Mounting position • Phase sequence of the current

Via the inverter the controller provides an increased reactive current for this test in single operation

The inverter is reactivated and excited by pressing key .

As soon as the increased reactive current is available, the inverter noise rises due to the high-frequency pulses of the IGBT modules. By pressing key the check of the generator CTs begins and is then automatically stopped.

6.3.4 Mains synchronization

By pressing key the inverter is re-activated.

Figure 6.21: Screenshot Mains Synchronisation By pressing key the synchronizing procedure is initiated. Based on the measurements of the generator- and mains voltage as well as on the rotor position, the control electronics of the CSCs synchronizes the generator voltage with the mains. IMPORTANT! Via the main contacts of the generator CT the zero voltage has always to be measured for safety reasons. Since the generator star point is not earthed a difference voltage of up to 30V (ac) can be measured via the terminals. By pressing the key, the synchronizing procedure is acknowledged and stopped.

6.3.5 Mains parallel operation with power

By pressing key the inverter is re-excited.

Figure 6.22: Screenshot Mains Parallel With Power By pressing key the synchronizing procedure is initiated. Based on the measurements of the generator- and mains voltage as well as on the rotor position, the control electronics of the CSCs synchronizes the generator voltage with the mains. The generator voltage is synchronized automatically to the mains voltage. After the synchronizing procedure is completed, the generator CB is closed. The generator and the CONCYCLE® Inverter now fed jointly into the mains. Dependent on the related specification, the power is controlled either acc. to the torque default value of the WPP control or in accordance with the P-n characteristic of the inverter sys-tem. For about 1min the system should now operate parallel to the mains. This test is acknowledged with key .

7. Operation of the System IMPORTANT! When the system is in automatic operation all covers and doors of the Woodward switchboard have to be shut all the time. The switchboard is to be operated in a trouble-free state only. Any change which may affect the safety has to be notified to the system operator immediately. Switchboard alterations can only be done if accepted by Woodward and the work must be supervised by a skilled electrician. If necessary, Wind Power Plants which include Woodward inverter systems should be equipped with additional supervision and protection devices in line with the applying safety regulations (e.g. regulations concerning technical tools, accident prevention specification etc.). IMPORTANT! After the system has slowed down and the inverter been disconnected from the supply voltage, any life components and power connections must not be touched because there is the danger of possi-bly charged capacitors. The respective warnings on and in the inverter system are to be observed:

7.1 Activities prohibited when the switchboard is in operation

When the switchboard is in operation the following is not allowed:

• To reach into dangerous areas. • To carry out maintenance work. • To carry out repair work. • To block inlets and outlets of the ventilating system. • To open doors.

Exception: By authorized and skilled electricians a panel can be opened!

7.2 Safety facilities It is strictly prohibited to change, dismantle or put any safety devices out of operation. Unprotected components can cause grave bodily harm. All safety devices, such as fuses, covers, obstruction means, must always be in good working order and properly fixed. It is not allowed to operate the switchboards if there are any faulty or insufficient safety devices.

Discharge Time Longer Than 1 Minute



8. Trouble and Troubleshooting

If any problems occurs in the system first of all read the system data and recorder data out of the CSC´s and save them on the hard disk of the laptop/PCs.

For fault indication the CSCs are provided with a number of potential-free signal contacts. For the actual allocation please see the related wiring diagram because dependent on the system type the terminal assignment may differ. Faults are also indicated at the CMW by two-coloured LEDs (see the following chapter “Fault Indication Via CMW-LED).

Based on the commissioning training an additional training on the subject „Service & Trouble shooting“ is offered by Woodward. For more details on Woodward training schemes (e.g. also on maintenance training) please phone number +49 (0) 2152 145 255.

Any tools or utilities used for operation, maintenance or repair work have to be in a safe-for-use condition and ought to be handled carefully. Inappropriate and dangerous usage of tools or such at or inside the system is not permitted.

8.1 Fault indication via CMW-LEDs Faults are indicated in plain text in the CMW display and via function „System Info“ in the CONCYCLE® customer tool. Aided by the CONCYCLE® Software „Customer Tool“ an online help is installed for the PC which contains a list of possible CMW fault messages. From this list information can be gathered about the action to be taken to solve an existing prob-lem. By activating the help file “CMW Messages” via the customer tool, the tree structure shown below is called up and from here the applying message can be selected:

8.2 Fault indication by CMW-LEDs The CWM is equipped with two-coloured LEDs for indication of operational and faulty conditions. In the following table the different signal messages are explained: See page 23, Chapter 6.2.2

8.3 Potentialfree contacts (relay outgoings) IMPORTANT! All messages of the potential-free contacts should be carefully evaluated and observed. Only this way a continuous supervision of the system and its safe operational condition can be guaranteed. The potential-free relay contacts of the CSC-HU controller or CSC-SU controller are looped at the terminal strip X2:1-32. These are miniature relays with the following switching capability:

• AC: NO contact 3 A, NC contact 1 A. • DC: NO and NC contacts 2 A

IMPORTANT! The switching capability of these contacts must not be exceeded in order to prevent damage. If a higher switching capability is needed additional power relays have to be interconnected. On the CSC controller an additional LED is allocated to each of the relays, indicating the physical switching conditions. The LEDs are always arranged in a group of four on the controller PCB.

Figure 8.2: Potentialfree Contacts

8.4 Voltage measuring terminals IMPORTANT! Electrical measurements are only allowed to be carried out by skilled electricians and by strictly ob-serving the applying safety regulations. For maintenance work and troubleshooting measuring signals are available on the XT terminal strip. Terminal strip XT5 is located in the control panel of the switchboard. Fused potentials are applied at the measuring terminals XT. Short-circuits at the terminals or at the connected measuring lines have to be avoided so that any related problems are prevented.

8.5 Adjustment of the position encoder after replacement or any problems

The position encoder needs to be re-adjusted after replacement of or working on the posi-tion encoder, or after the message “Commissioning Not Carried Out”.

Conditional on the software version implemented, the position encoder is adjusted according to one of the two following methods:

• As from software version 3.5.3 the adjustment is part of the integrated commissioning program. For adjustment please see chapter. „Calibration Of The Position Encoder“ in chapter „Electrical Commissioning“.

• Up to software version 3.5.3 the following adjustment method applies (see 8.5.1)

The software version is stated on the INFO page of the CMW.



8.5.1 Adjustment of the position encoder up to software version 3.5.3 Tools needed:

• a small screw driver (slot-type) • strip connector (1.5 mm2)

Procedure:

1. At the control device of the mains inverter (voltage inverter) the wires applied at terminals X1-1 and X2-4 have to be removed and then to be connected to a strip connector.

2. The key switch on the CONCYCLE® operating unit CMW to be put into position „Manual“.

3. Then press key at the CMW and by the page selection key it is changed to

the pass-word query:

Figure 8.4: Store function

4. For the password input the following key combination has to be pressed:

5. Key has to be pressed again and then you are in the window »Adjustment of Posi-tion En-coder«.

Position Encoder adjustment



IMPORTANT! For the position encoder adjustment the speed of the WPP must be within the range of the excita-tion window. As described below, the adjustment of the position encoder is done in two steps: firstly the coarse adjustment which is then followed by the fine adjustment.

7. By pressing key at the CMW the generator is excited. An angle of 90o ( +/- 1° ) is to be set by changing the position encoder offset in 20o steps. This angle is accepted and acti-vated in the control after pressing the key at the CMW.

8. Assuming a generator angle of α the position encoder offset can be discovered by the fol-

lowing formula:

Position encoder offset_new = Position encoder offset_old + (α- 90)

9. After the coarse adjustment has been completed, the generator is de-excited by pressing

the key at the CMW.

10. The control wires previously disconnected from the mains control device CSC-SUR (vol-tage inverter) are re-connected to terminals X1-1 and X2-4.

11. Key on the CMW is pressed again. Now the generator is re-excited and the mains in-verter connected as well. For the fine adjustment the generator angle is to be set to 90°.

12. After the adjustment procedure is completed the key switch is to be changed to position

„AUTO“ again. Value of the parameter “Position Encoder Offset” has to be noted down and the Woodward Service Department is to be informed accordingly.

CAUTION! If the input signals „Excitation Release“ and „Load Request“ are given by the higher-level WPP control at the end of the adjustment procedure then the CONCYCLE® System does not change to the „Standstill“ mode but directly turns into “Mains Parallel Operation”!



8.6 Claim Liste (Return Advice Note) IMPORTANT! The Woodward Service Department should only be contacted after all relevant data have been noted in a copy the Claim List. Only then the fault messages should be cancelled! IMPORTANT! The related files of the recorded faults have also to be sent to the Woodward Service Department with duly reference to the Claim List.

9. Instruction in case of fault event by the Crow-Bar protection (Optional, if installed)

9.1 Function of the Crowbar supervision The crow-bar protects the intermediate DC-circuit. The activation of the crow-bar during normal op-erating conditions is not necessary and unusual. Nevertheless it could be that the crow-bar has been switched on. In that case it is justified due to a misdemeanor of other components. The com-ponents must be checked then. To protect the Crow-Bar components (dI/dt choke, thyristors) against undesirably current flow and with it high temperatures the components are fitted with thermal switches with a threshold > 80°C and a thermal protection relay (F40) which isolates the primary circuit from the supervision circuit. The relay is switched into the “Ringline shut down” circuit which switched off the system immediate-ly in case of failure. The fault “M24: Ringline shut down” will be displayed and recorded in the Customer Tool. The current flow through the system and therewith through the components will be disconnected immediately. It is impossible to reset the Relay (F40) remotely. The service must reset the relay manually after they have checked the components. If necessary change the components. The dI/dt choke and thyristors are designed for a maximum temperature of 125°C. To insure a safe operating of the components the threshold of the thermal switches are selected to 80°C.

Systems with Crow-Bar resistance. The supervision components are marked red.



Schematic

9.2 Actions in case of fault event Shall it come to a non resettable fault event with the fault “M24: Ringline shut down” the following actions should be executed at site: • Analysis of Data- and Eventrecorder:

Check whether the crow-bar firing was justifiable. The crow-bar will only fired in case of high DC-Intermediate voltage. This will be displayed in the Data- and Eventrecorder with the fault indication “F3: DC-Link volt. to high”.

• Check of the temperature indicator: The crow-bar thyristors are equipped with temperature stripes which indicates the max. temperature. Check the signalization of the indicators. If the temperature indicates >77°C (see picture: Temperature Indicator) the concerned thyristor has to be changed. In that case a new temperature indicator has to be sticking at the new thyristor.

• Check of the thyristor firing unit –A5 (CSC3-ZS-F) In normal condition with active 24VDC supply voltage the contact X2:7 and X2:8 must be closed. The green LED (see picture: Thyristor Firing Unit, blue arrow) must switched on for 1,2 s when unplugging the fiber optic cable (see picture: Thyristor Firing Unit, red arrow).

• Check of the thermal release function: Check whether the red LED (2) on the thermal protection relay (F40) is on. If true the su-pervision circuit has opened. Press the reset button (1). The LED must switch off. Check the supervision circuit. The primary circuit with the thermal switches must be checked with a continuity tester. T1 and T2 must have low resistance. With opening of the circuit the relay –F40 must react and switch on LED (2). With closed circuit LED (2) must switched off when pressing reset. If not the faulty thermal switches or the relay must be changed. Repeat the test after changing the components.



Is the functioning of the supervision circuit ok the thyristors –V1, -V2, -V3 has to be changed.

• Check of dI/dt chokes: Check the inductivity and the resistance of the dI/dt chokes -L3, -L4. Nominal value: 40µH / 3,3 mOhm +/-10%. If necessary change the chokes.

• Document the fault and report them immediately to Woodward service. Send the read out data’s (Data- and Event recorder) to Woodward service.
