3. Protections functions

The IED features, three-phase, multi-slopestabilized (biased) stage transformerdifferential protection and an instantaneousstage to provide fast and selective protectionfor phase-to-phase short-circuit, windinginterturn fault and bushing flash-overprotection. Besides second harmonic restraintan advanced waveform-based blockingalgorithm ensures stability at transformerenergization and a fifth harmonic restraintfunction ensures good protection stability atmoderate overexcitation of powertransformers. Sensitive restricted earth-faultprotection (REF) completes the overalldifferential protection providing detection ofeven single phase-to-earth faults close to theneutral earthing point of the transformer.Either the conventional high-impedancescheme or a numerical low-impedancescheme can be selected for protection of thetransformer windings. When low-impedanceREF protection is used neither stabilizingresistors nor varistors are needed and as afurther benefit the transforming ratio of theneutral earthing CTs can differ from those ofthe phase current transformers. Due to itsunit protection character and absoluteselectivity REF does not need to be time-graded with other protection schemes, and

therefore high-speed fault clearance can beachieved.

The IED also incorporates a thermal overloadprotection function, which supervises thethermal stress of the transformer windings toprevent premature aging of the insulation ofthe windings. Multiple stages of short-circuit,phase-overcurrent, negative-phase-sequenceand earth-fault back-up protection areseparately available for both sides of thepower transformer. Earth-fault protectionbased on the measured or calculated residualvoltage is also available. Depending on thechosen standard configuration the IED alsofeatures three-phase overvoltage protection,three-phase undervoltage protection andresidual overvoltage protection. Further, theIED also offers circuit-breaker failureprotection.

Enhanced with optional hardware andsoftware, the IED also features three lightdetection channels for arc fault protection ofthe circuit breaker, busbar and cablecompartment of metal-enclosed indoorswitchgear.

The arc-fault protection sensor interface isavailable on the optional communicationmodule. Fast tripping increases personnelsafety and limits switchgear damage, shouldan arc fault occur.

4. Application

RET615 provides main protection for two-winding power transformers and powergenerator-transformer blocks. As of now,there are eight standard configurationsoffering comprehensive protection functionsfor detection and elimination of operationaldisturbance conditions and powertransformer faults.

The standard configurations A, C, E and Gare intended for power transformers withearthed HV-side neutrals. The A and Econfiguration features low impedance REFprotection while the C and G configurationoffers high impedance REF protection. The B,D, F and H configurations fit transformerswith solidly-earthed LV-side neutral or the LVside with a neutral earthing resistor. The B,D, F and H configurations also fitapplications including a separate earthingtransformer located within the area ofprotection. The A, B , E, and F configurationsalso suit applications, where the turns ratio ofthe CT of the neutral earthing circuit differsfrom the turns ratio of the line CTs. The C, D,G and H configurations require that the turnsratios of the CTs are equal.

Standard configurations E, F, G and Hinclude phase-voltage protection and

measurement functions which provide two-stage power transformer overvoltage andundervoltage protection and/or supervision.

The optional RTD/mA module offered for thestandard configurations A-D allow up to eightanalog signals to be measured via the sixRTD inputs and the two mA inputs usingtransducers. The RTD and mA inputs can beused for measuring the oil temperature at thebottom and top of the transformer.Furthermore, the RTD/mA inputs can be usedfor measuring the ambient air temperature.The RTD inputs also offer thermal protectionof dry-type power transformers fitted withPt-100 temperature sensors. Temperaturemeasurement over the RTD/mA inputsextends the function of the three-phasethermal overload protection of the IED.Further, one of the RTD inputs can also beused as a direct resistance measuring inputfor position information of the on-load tapchanger. Alternatively, the tap changerposition indication can be obtained via a mA-transducer. The analog temperature or tapchanger position values can, if required, besent using analog horizontal GOOSEmessaging to other IEDs. Analog values canalso, vice versa, be received from other IEDsover the station bus, thus improving theextent of relevant information.

5. Supported ABBsolutions

ABB’s 615 series protection and control IEDstogether with the COM600 StationAutomation device constitute a genuine IEC61850 solution for reliable power distributionin utility and industrial power systems. Tofacilitate and streamline the systemengineering ABB’s IEDs are supplied withConnectivity Packages containing acompilation of software and IED-specificinformation including single-line diagramtemplates, a full IED data model includingevent and parameter lists. By utilizing theConnectivity Packages the IEDs can bereadily configured via the PCM600 Protectionand Control IED Manager and integrated withthe COM600 Station Automation device or theMicroSCADA Pro network control andmanagement system.

The 615 series IEDs offer native support forthe IEC 61850 standard also including binaryand analog horizontal GOOSE messaging.Compared with traditional hard-wired inter-device signaling, peer-to-peer communicationover a switched Ethernet LAN offers anadvanced and versatile platform for powersystem protection. Fast software-basedcommunication, continuous supervision ofthe integrity of the protection andcommunication system, and inherentflexibility for reconfiguration and upgradesare among the distinctive features of theprotection system approach enabled by thefull implementation of the IEC 61850substation automation standard.

At the substation level COM600 uses the datacontent of the bay level IEDs to offerenhanced substation level functionality.COM600 features a web-browser based HMIproviding a customizable graphical displayfor visualizing single line mimic diagrams forswitchgear bay solutions. The SLD feature isespecially useful when 615 series IEDswithout the optional single line diagramfeature are used. Further, the web HMI ofCOM600 offers an overview of the wholesubstation, including IED-specific single linediagrams, thus enabling convenientinformation accessibility. To enhancepersonnel safety, the web HMI also enablesremote access to substation devices andprocesses. Furthermore, COM600 can be usedas a local data warehouse for technicaldocumentation of the substation and fornetwork data collected by the IEDs. Thecollected network data facilitates extensivereporting and analyzing of network faultsituations using the data historian and eventhandling features of COM600. The datahistorian can be used for accurate processperformance monitoring by following processand equipment performance calculations withreal-time and history values. Betterunderstanding of the process behaviour byjoining time-based process measurementswith production and maintenance eventshelps the user in understanding the processdynamics.

6. Control

The IED offers control of one circuit breakerwith dedicated push-buttons for circuit

breaker opening and closing. Further, theoptional large graphical LCD of the IED’sHMI includes a single-line diagram (SLD)with position indication for the relevantcircuit breaker. Interlocking schemes


18 ABB

required by the application are configuredusing the signal matrix or the applicationconfiguration feature of PCM600.

7. Measurement

The IED continuously measures the highvoltage (HV) side and the low-voltage (LV)side phase currents and the neutral current ofthe protected transformer. In addition, theIED calculates the symmetrical componentsof the currents and voltages, maximumcurrent demand value over a user-selectablepre-set time frame, the active and reactivepower, the power factor, and the active andreactive energy values. Calculated values arealso obtained from the protection andcondition monitoring functions of the IED.Depending on the standard configuration, theIED also measures the phase voltages, theresidual voltage and the voltage sequencecomponents.

For standard configuration A, B, C and D RTD/mA inputs are offered as an option. By meansof the optional RTD/mA module the IED canmeasure up to eight analog signals such astemperature, pressure and tap changerposition values via the six RTD inputs or thetwo mA inputs using transducers.

The values measured can be accessed locallyvia the user interface on the IED front panelor remotely via the communication interfaceof the IED. The values can also be accessedlocally or remotely using the web-browserbased user interface.

8. Disturbance recorder

The IED is provided with a disturbancerecorder featuring up to 12 analog and 64binary signal channels. The analog channelscan be set to record either the waveform or

the trend of the currents and voltagemeasured.

The analog channels can be set to trigger therecording function when the measured valuefalls below or exceeds the set values. Thebinary signal channels can be set to start arecording on the rising or the falling edge ofthe binary signal or both.

By default, the binary channels are set torecord external or internal IED signals, forexample the start or trip signals of the IEDstages, or external blocking or controlsignals. Binary IED signals such as aprotection start or trip signal, or an externalIED control signal over a binary input can beset to trigger the recording. The recordedinformation is stored in a non-volatilememory and can be uploaded for subsequentfault analysis.

9. Event log

To collect sequence-of-events (SoE)information, the IED incorporates a non-volatile memory with a capacity of storing512 events with associated time stamps. Thenon-volatile memory retains its data also incase the IED temporarily loses its auxiliarysupply. The event log facilitates detailed pre-and post-fault analyses of feeder faults anddisturbances. The increased capacity toprocess and store data and events in the IEDoffers prerequisites to support the growinginformation demand of future networkconfigurations.

The SoE information can be accessed locallyvia the user interface on the IED front panelor remotely via the communication interfaceof the IED. The information can further beaccessed, either locally or remotely, using theweb-browser based user interface.


ABB 19

10. Recorded data

The IED has the capacity to store the recordsof 32 latest fault events. The records enablethe user to analyze the power system events.Each record includes current, voltage andangle values, time stamp, etc. The faultrecording can be triggered by the start signalor the trip signal of a protection block, or byboth. The available measurement modesinclude DFT, RMS and peak-to-peak. Inaddition, the maximum demand current withtime stamp is separately recorded. By default,the records are stored in a non-volatilememory.

11. Condition monitoring

The condition monitoring functions of theIED constantly monitors the performance andthe condition of the circuit breaker. Themonitoring comprises the spring chargingtime, SF6 gas pressure, the travel-time andthe inactivity time of the circuit breaker.

The monitoring functions provide operationalCB history data, which can be used forscheduling preventive CB maintenance.

12. Trip-circuitsupervision

The trip-circuit supervision continuouslymonitors the availability and operability ofthe trip circuit. It provides open-circuitmonitoring both when the circuit breaker isin its closed and in its open position. It alsodetects loss of circuit-breaker control voltage.

13. Self-supervision

The IED’s built-in self-supervision systemcontinuously monitors the state of the IEDhardware and the operation of the IEDsoftware. Any fault or malfunction detectedwill be used for alerting the operator.

A permanent IED fault will block theprotection functions to prevent incorrectoperation.

14. Access control

To protect the IED from unauthorized accessand to maintain information integrity, the IEDis provided with a four-level, role-basedauthentication system with administrator-programmable individual passwords for theviewer, operator, engineer and administratorlevel. The access control applies to the front-panel user interface, the web-browser baseduser interface and the PCM600 tool.

15. Inputs and outputs

The IED is equipped with six phase-currentinputs and one neutral-current input or sixphase-current inputs, one neutral-currentinput, three phase-voltage inputs and oneresidual voltage input. The rated level of thecurrent inputs is 1/5 A and selectable in theIED software. The three phase-voltage inputsand the residual-voltage input covers therated voltages 60-210 V. Both phase-to-phasevoltages and phase-to-earth voltages can beconnected. In addition, the binary inputthresholds 18…176 V DC are selected byadjusting the IED’s parameter settings.

All binary inputs and outputs contacts arefreely configurable with the signal matrix orapplication configuration functionality ofPCM600.


20 ABB

As an option for standard configurations A,B, C and D, the IED offers six RTD inputsand two mA inputs. By means of the optionalRTD/mA module the IED can measure up toeight analog signals such as temperature,pressure and tap changer position values viathe six RTD inputs or the two mA inputsusing transducers. The values can, apart frommeasuring and monitoring purposes, be used

for tripping and alarm purposes using theoffered optional multipurpose protectionfunctions.

16. Communication

The IED supports a range of communicationprotocols including IEC 61850, IEC

60870-5-103, Modbus® and DNP3.Operational information and controls areavailable through these protocols. However,some communication functionality, forexample, horizontal communication betweenthe IEDs, is only enabled by the IEC 61850communication protocol.

The IEC 61850 communicationimplementation supports all monitoring andcontrol functions. Additionally, parametersettings, disturbance recordings and faultrecords can be accessed using the IEC 61850protocol. Disturbance recordings are availableto any Ethernet-based application in thestandard COMTRADE file format. The IEDsupports simultaneous event reporting to fivedifferent clients on the station bus.

The IED can send binary signals to otherIEDs (so called horizontal communication)using the IEC 61850-8-1 GOOSE (GenericObject Oriented Substation Event) profile.Binary GOOSE messaging can, for example,be employed for protection and interlocking-based protection schemes. The IED meets theGOOSE performance requirements fortripping applications in distributionsubstations, as defined by the IEC 61850standard. Further, the IED supports thesending and receiving of analog values usingGOOSE messaging. Analog GOOSEmessaging enables fast transfer of analogmeasurement values over the station bus,thus facilitating for example sharing of RTDinput values, such as surroundingtemperature values, to other IED applications.

The IED offers an optional second Ethernetbus to enable the creation of a self-healingEthernet ring topology. The IEDcommunication module options include bothgalvanic and fibre-optic Ethernetcombinations. The communication moduleincluding one fibre-optic LC port and twogalvanic RJ-45 ports is used when the ring

between the IEDs is built using CAT5 STPcables. The LC port can in this case be usedfor connecting the IED to communicationports outside the switchgear. Thecommunication module including three RJ-45ports is used when the whole substation busis based on CAT5 STP cabling.

The self-healing Ethernet ring solutionenables a cost efficient communication ringcontrolled by a managed switch with rapidspanning tree protocol (RSTP) support to becreated. The managed switch controls theconsistency of the loop, routes the data andcorrects the data flow in case of acommunication disturbance. The IEDs in thering topology act as unmanaged switchesforwarding unrelated data traffic. TheEthernet ring solution supports theconnection of up to thirty 615 series IEDs. Ifmore than 30 IEDs are to be connected, it isrecommended that the network is split intoseveral rings with no more than 30 IEDs perring. The self-healing Ethernet ring solutionavoids single point of failure concerns andimproves the reliability of thecommunication. The solution can be appliedfor the Ethernet-based IEC 61850, Modbusand DNP3 protocols.

All communication connectors, except for thefront port connector, are placed on integratedoptional communication modules. The IEDcan be connected to Ethernet-basedcommunication systems via the RJ-45connector (100Base-TX) or the fibre-optic LCconnector (100Base-FX). If connection to aserial bus is required, the 10-pin RS-485 screw-terminal or the fibre-optic ST connector canbe used.

Modbus implementation supports RTU, ASCIIand TCP modes. Besides standard Modbusfunctionality, the IED supports retrieval oftime-stamped events, changing the activesetting group and uploading of the latest faultrecords. If a Modbus TCP connection is used,five clients can be connected to the IEDsimultaneously. Further, Modbus serial andModbus TCP can be used in parallel, and if


22 ABB

required both IEC 61850 and Modbusprotocols can be run simultaneously.

The IEC 60870-5-103 implementationsupports two parallel serial bus connectionsto two different masters. Besides basicstandard functionality, the IED supportschanging of the active setting group anduploading of disturbance recordings in IEC60870-5-103 format.

DNP3 supports both serial and TCP modesfor connection to one master. Further,changing of the active setting group issupported.

When the IED uses the RS-485 bus for theserial communication, both two- and fourwire connections are supported. Terminationand pull-up/down resistors can be configuredwith jumpers on the communication card soexternal resistors are not needed.

The IED supports the following timesynchronization methods with a time-stamping resolution of 1 ms:

Ethernet-based:

• SNTP (Simple Network Time Protocol)

With special time synchronization wiring:

• IRIG-B (Inter-Range Instrumentation Group- Time Code Format B)

In addition, the IED supports timesynchronization via the following serialcommunication protocols:

18. Local HMI

The IED is available with two optionaldisplays, a large one and a small one. Thelarge display is suited for IED installationswhere the front panel user interface isfrequently used and a single line diagram isrequired. The small display is suited forremotely controlled substations where theIED is only occasionally accessed locally viathe front panel user interface.

Both LCD displays offer front-panel userinterface functionality with menu navigationand menu views. However, the large displayoffers increased front-panel usability with lessmenu scrolling and improved informationoverview. In addition, the large displayincludes a user-configurable single linediagram (SLD) with position indication forthe associated primary equipment.Depending on the chosen standard

configuration, the IED displays the relatedmeasuring values, apart from the defaultsingle line diagram. The SLD view can alsobe accessed using the web-browser baseduser interface. The default SLD can bemodified according to user requirements byusing the graphical display editor in PCM600.

The local HMI includes a push button (L/R)for local/remote operation of the IED. Whenthe IED is in the local mode, the IED can beoperated only by using the local front paneluser interface. When the IED is in the remotemode, the IED can execute commands sentfrom a remote location. The IED supports theremote selection of local/remote mode via abinary input. This feature facilitates, forexample, the use of an external switch at thesubstation to ensure that all IEDs are in thelocal mode during maintenance work andthat the circuit breakers cannot be operatedremotely from the network control centre.

19. Mounting methods

By means of appropriate mountingaccessories the standard IED case for the 615series IED can be flush mounted, semi-flushmounted or wall mounted. The flushmounted and wall mounted IED cases canalso be mounted in a tilted position (25°)using special accessories.

Further, the IEDs can be mounted in anystandard 19” instrument cabinet by means of19” mounting panels available with cut-outsfor one or two IEDs. Alternatively, the IEDcan be mounted in 19” instrument cabinetsby means of 4U Combiflex equipment frames.

For the routine testing purposes, the IEDcases can be equipped with test switches,

type RTXP 18, which can be mounted side byside with the IED cases.

Mounting methods:

• Flush mounting• Semi-flush mounting• Semi-flush mounting in a 25° tilt• Rack mounting• Wall mounting• Mounting to a 19" equipment frame• Mounting with a RTXP 18 test switch to a

19" rack

20. IED case and IEDplug-in unit

For safety reasons, the IED cases for currentmeasuring IEDs are provided withautomatically operating contacts for short-circuiting the CT secondary circuits when aIED unit is withdrawn from its case. The IEDcase is further provided with a mechanicalcoding system preventing current measuringIED units from being inserted into a IED casefor a voltage measuring IED unit and viceversa, i.e. the IED cases are assigned to acertain type of IED plug-in unit.

21. Selection andordering data

The IED type and serial number labelidentifies the protection IED. The label is

placed above the HMI on the upper part ofthe plug-in-unit. An order number label isplaced on the side of the plug-in unit as wellas inside the case. The order number consistsof a string of codes generated from the IED'shardware and software modules.

Use the ordering key information to generatethe order number when ordering completeIEDs.

23. Tools

The IED is delivered as a pre-configured unit.The default parameter setting values can bechanged from the front-panel user interface,the web-browser based user interface(WebHMI) or the PCM600 tool incombination with the IED-specificconnectivity package.

The Protection and Control IED ManagerPCM600 is available in three differentvariants, that is PCM600, PCM600Engineering and PCM600 Engineering Pro.Depending on the chosen variant, PCM600offers extensive IED configuration functionssuch as IED signal configuration, applicationconfiguration, graphical display configurationincluding single line diagram configuration,and IEC 61850 communication configurationincluding horizontal GOOSE communication.

When the web-browser based user interfaceis used, the IED can be accessed either

locally or remotely using a web browser (IE7.0 or later). For security reasons, the web-browser based user interface is disabled bydefault. The interface can be enabled withthe PCM600 tool or from the front panel userinterface. The functionality of the interfacecan be limited to read-only access by meansof PCM600.

The IED connectivity package is a collectionof software and specific IED information,which enable system products and tools toconnect and interact with the IED. Theconnectivity packages reduce the risk oferrors in system integration, minimizingdevice configuration and set-up times.Further, the Connectivity Packages for the615 series IEDs include a flexible update toolfor adding one additional local HMI languageto the IED. The update tool is activated usingPCM600 and enables multiple updates of theadditional HMI language, thus offeringflexible means for possible future languageupdates.
