The manual should be read inconjunction with the ALSPA MV3000 Getting Started Manual T1676.

This manual should be regarded as part of the ALSPA MV3000 twelve pulse system. Itshould be retained for the life of the product and should be passed on to anysubsequent owner or user.

To use an ALSPA MV3000 DELTA system in twelve pulse configuration, refer to T1689,the Technical Manual for MV3000 DELTA.

1.2 About the ALSPA MV3000 Twelve Pulse System

The twelve pulse system is used to reduce harmonic currents generated by the driveand, in conjunction with the drive DC Link capacitors, to reduce ripple on the DC Linkvoltage. The system comprises three add-on components which operate with astandard MV3000 drive to obtain the ripple reduction:

– a Twelve Pulse Adapter which is an additional rectifier bridge controlled bythe MV3000 control board and should only be used with an MV3000controller.

– a Twelve Pulse Transformer (TPT) which provides phase shifted mains suppliesto the MV3000 and to the twelve pulse adapter, and which takes the place ofan AC line reactor. Note that AC line reactors are required for systems havingmore than one drive per TPT, see Section 3.5.

– an Interbridge Transformer (IBT) which combines the DC outputs from theadapter and the MV3000 rectifier to produce the DC link voltage withreduced twelve pulse ripple.

The circuit diagram of a twelve pulse system is shown inside the front cover, and ageneral view of the main components is shown in Figure 1-1 and inside the front cover.

ALSPA MV3000 Twelve Pulse System 3. System Design


3. System Design

3.1 Introduction

This section describes system functioning and recommended methods of protectingsystem components.

3.2 Functional Description(Refer to the circuit diagram inside the front cover)

The twelve pulse system is designed to reduce harmonic currents generated by theMV3000 on the supply.

The twelve pulse transformer has star-wound and delta-wound secondaries which givetwo 3-phase outputs phase shifted by 30o with respect to each other. One output isrectified by the MV3000 rectifier and the other by the twelve pulse adapter, the tworectified outputs are combined in the interbridge transformer.

3.3 Protection

The MV3000 drive and the components of the twelve pulse system must be protectedagainst possible malfunctions, generally in three areas comprising:

1) Thermal protection.

2) Protection against short circuits.

3) Protection against harmonic pollution of the supply.

3.3.1 Thermal Protection

Several methods are employed to protect components of the twelve pulse systemagainst overheating

1) The MV3000 protects itself and the twelve pulse adapter by monitoring heatsinktemperatures. The drive will trip and disable its output if it detects an over-temperature condition.

2) Twelve pulse transformers recommended and supplied by !"#$ are providedwith temperature sensing devices (thermistors) positioned so that they will detectan over-temperature condition in either of the secondary windings. As supplied,the six thermistors are connected in series via a link as shown on the front covercircuit diagram, and are accessible at a terminal block on the twelve pulsetransformer top panel.

The user connections are by default configured to allow all six thermistors to bemonitored by a single Monitor Protection Relay. The transformer secondaries maybe monitored individually by removing the link that interconnects the two sets ofsensors and connecting each set to a separate monitor protection relay.A suitable relay is the Telemecanique LT3–SA00MW model thermistor monitoringrelay, the output can be used to trip the MV3000 and also a primary sideinterrupting device. Supplies for the monitoring relay must be derived from theinput side of the supply breaker or additional user-supplied logic is required toenable start-up.

3. System Design ALSPA MV3000 Twelve Pulse System


3.3.2 Short Circuit Protection

Data provided in Sections 2.3.3 to 2.3.6 should be used to select suitable protectiondevices for the primary side of the twelve pulse transformer.

!"#$ recommends that the supply cables from each secondary winding of thetwelve pulse transformer are protected by fuses or circuit breakers as shown in the frontcover circuit diagram.

3.3.3 Harmonic Pollution

Failure of fuses in either one of the secondary circuits would result in 6-pulse operationand hence increased harmonic currents in the supply.

Figure 3-1 shows an arrangement where secondary fuses are monitored by a miniaturecircuit breaker (MCB). The normally closed contacts can be used to complete theMV3000 INTERLOCK line (see the MV3000C Getting Started Manual). If a fuseruptures the interlock line is opened and the MV3000 will trip. A suitable MCB is aSiemens type 3RV16 11-0BD10 with auxiliary contact 3RV19 01-1E. This MCB isavailable from !"#$.

Miniature CircuitBreaker.

To DriveControl Inputs

Figure 3-1 Secondary fuse monitoring

As shown in the circuit diagram (front cover), this arrangement can be connected inseries with a similar output from a main transformer temperature monitor to trip theMV3000 and/or a supply interrupt device such as a circuit breaker.

There is a small possibility of fault conditions occurring, after successful commissioning,that will allow the drive to operate normally, but to draw its power via either its internalrectifier or the twelve pulse adapter. In this condition the system will generate a greaterlevel of harmonics on the supply. In theory this condition could remain indefinitely. Toprevent the resulting additional voltage distortion becoming detrimental to otherequipment on the same supply, the rating of that supply should be at least 5 times therating of the twelve pulse transformer.



To provide complete protection for this condition is complex, however a measure ofprotection can be provided by temperature monitoring of the twelve pulse transformerand monitoring the secondary protection devices, then tripping the drive via theinterlock circuit.

As the above solution does not cover all the possible faults, it is recommended that theDC current balance between the two DC input wires to the interbridge transformer(i.e. RECT+ from the drive and RECT+ from the twelve pulse adapter) is checkedperiodically – the unit is operating correctly if there is no more than 55% of the totalcurrent in either path. See Section 6, Preventive Maintenance.

3.4 Larger Twelve Pulse Systems

This manual explains how to install a basic twelve pulse system, where one MV3000 iswired to a dedicated twelve pulse transformer and twelve pulse adapter.

Other Twelve Pulse arrangements are possible, e.g. multiple inverters supplied from asingle Twelve Pulse fed DC link or multiple Twelve Pulse rectifiers fed from one TwelvePulse transformer. These systems are outside the scope of this manual but furtherinformation can be obtained from !"#$.

Figure 3-2 shows the layout for a typical cabinet installation for EMC compliance.

3.5.1 Segregation Rules

When routing cables for the twelve pulse system there are simple segregation ruleswhich should be followed, where possible. These are shown on Figure 3-2 and are:

• Power input and output cables should be separated by at least 300 mm (12 in).

• Power and control cables should be separated by at least 300 mm (12 in).

• Power and control cables should cross each other at right angles.

ALSPA MV3000 Twelve Pulse System 7. Diagnostics


7. Diagnostics

7.1 Fault Monitoring

The drive continuously monitors the performance of the MV3000 and twelve pulseadapter, also the output from any monitoring relays or breakers which may have beenwired into the MV3000 interlock or other digital input by the user. A malfunction of thesystem will result in the MV3000 indicating a warning or a trip, depending on thenature of the fault.

To aid fault diagnosis the drive keeps a log of warnings and trips, which are entered aswarning or trip fault codes. Use of the log is explained in Section 6 of the GettingStarted Manual T1676, which also shows how to view the fault codes and what actionto take in the event of a warning or trip. This section of T1676 also explains how toreset a trip.

7.2 Warnings Specific to the Twelve Pulse System

The drive illuminates the WARNING indicator if a fault occurs which is not sufficientlyserious to trip the drive. Warnings are not latched, so that if the reason for the warningis cleared the WARNING indicator will extinguish, though a record may be maintainedin the History Log to aid possible further diagnosis (if configured by the user).

The warning fault code and possible diagnosis is given in Table 7-1.

Press the ? key on the Keypad to view warnings. Further information is provided inT1676.

Table 7-1 Warning diagnosis

WarningCode

The heatsink temperatures ofthe MV3000 and the twelvepulse adapter are monitored.

High temperature

Low temperature

A warning will be issued if the higher of the monitored inputtemperatures (Menu 45) exceeds a pre-set limit (which isdrive-size dependent). Parameter 11.08 shows the maximumof these two values.

Menu 45 provides greater detail. P45.03 shows the MV3000input temperature, P45.04 shows that of the twelve pulseadapter.

Check for adequate ventilation of both rectifier assemblies orfor the drive/adapter fans not operating.

A warning will be issued if the temperature of either heatsinkfalls below 5oC. P45.03 and P45.04 must be viewed to seewhich heatsink has the lowest temperature and thereforecaused the warning (as P11.08 only reports the highest).

Check:

1. Thermistor feedback, control cables.

2. The rectifier with the low temperature heatsink may notbe operating. Check pre-charge fuses, twelve pulsetransformer secondary winding fuses, transformeroutput, rectifiers.

7. Diagnostics ALSPA MV3000 Twelve Pulse System


7.3 Trips Specific to the Twelve Pulse System

The drive flashes the TRIPPED indicator if a serious fault has caused it to trip. Trips arelatched and the drive cannot be used until the fault is cleared and the drive is reset asdescribed in the Getting Started Manual.

A list of trip fault codes and possible diagnosis is given in Table 7-2.

Press the ? key on the Keypad to view trips. Further information is provided inT1676.
