Feeder ProtectionREF6151MRS756379Issue: February 2008Status: ApprovedVersion: B / 22 Feb 20081. DescriptionREF615 is a dedicated feeder protection relaydesigned for the protection, measurementand supervision of utility substations andindustrial power systems. Re-engineered fromthe ground up, the relay has been guided bythe IEC 61850 standard for communicationand interoperability of substation automationdevices.The relay provides main protection for overheadlines and cable feeders in distributionnetworks. The relay is also used as back-upprotection in applications, where an independentand redundant protection system isrequired.Depending on the preconfiguration made,the relay is adapted for the protection ofoverhead line and cable feeders in isolatedneutral, resistance earthed, compensated andsolidly earthed networks. Once the standardconfiguration relay has been given the application-specificsettings, it can directly be putinto service.The 615 series relays support a range of communicationprotocols including IEC 61850with GOOSE messaging and Modbus®.2. StandardconfigurationsThe feeder protection relay REF615 is availablewith four alternative standard configurations.The table below indicates the functionssupported by the different relay configurations.Standard configuration functionalityOvercurrent anddirectional earth-faultprotectionStd.conf.AStd.conf.BOvercurrent and nondirectionalearth-fault protectionStd.conf.CProtectionThree-phase non-directional overcurrent,low-set stage • • • •Three-phase non-directional overcurrent,high-set stage, instance 1 • • • •Three-phase non-directional overcurrent,high-set stage, instance 2 • • • •Three-phase non-directional overcurrent,instantaneous stage • • • •Directional earth-fault, low-set stage,instance 1 • • - -Directional earth-fault, low-set stage,instance 2 • • - -Directional earth-fault, high-set stage • • - -Non-directional earth-fault, high-set stage(cross country earth-fault) • • - -Transient/intermittent earth-fault • • - -Non-directional earth-fault, low-set stage - - • •Non-directional earth-fault, high-set stage - - • •Non-directional earth-fault,instantaneous stage- - • •Std.conf.DABB

The actualinterlocking scheme is implemented outside the relay. The binary input serves as a “master interlocking input”and when energized it will enable circuit breaker closing.2) Extended interlocking functionality: The circuit breaker interlocking scheme is implemented in the relayconfiguration, based on primary equipment position information (via binary inputs) and the logical functionsavailable. The signal matrrix tool of PCM600 can be used for modifying the interlocking scheme to suit yourapplication.3. Protection functionsThe relay offers overcurrent and thermaloverload protection, directional and nondirectionalearth-fault protection, sensitive earthfaultprotection, phase discontinuity protection,transient/intermittent earth-fault protectionand three-pole multi-shot auto-reclosefunctions for overhead line feeders.Enhanced with optional hardware and software,the relay also features three lightdetection channels for arc fault protection ofthe circuit breaker, busbar and cable compartmentof metal-enclosed indoor switchgear.The arc-fault protection sensor interface isavailable on the optional communicationmodule. Fast tripping increases personalsafety and limits material damage within theswitchgear in an arc fault situation.ABB

Feeder ProtectionREF6151MRS756379The standard configurations C and D offernon-directional earth-fault protection for outgoingfeeders including phase current transformers.The residual current for the earthfaultprotection is derived from the phasecurrents. When applicable, the core-balancecurrent transformers can be used for measuringthe residual current, especially whensensitive earth-fault protection is required.Fig. 4 Substation O/C and E/F protection using the standard configuration C or D withrelevant options. In the incoming feeder bay the unemployed protection functions areuncoloured and indicated with a dashed block outline. The busbar protection is basedon the interlocking principle, where the start of the O/C protection of the outgoing feedersends a blocking signal to the instantaneous O/C stage of the incoming feeder. In theabsence of the blocking signal, the O/C protection of the incoming feeder will clear theinternal switchgear (busbar) fault.ABB

Feeder ProtectionREF6155. ControlThe relay offers control of one circuit breakerwith dedicated push-buttons for opening andclosing. Interlocking schemes required bythe application are configured with the signalmatrix tool in PCM600.6. MeasurementThe relay continuously measures the phasecurrents, the symmetrical components ofthe currents and the residual current. If therelay includes directional earth-fault protection,it also measures the residual voltage. Inaddition, the relay calculates the maximumdemand value over a user-selectable pre-settime frames, the thermal overload of the protectedobject, and the phase unbalance valuebased on the ratio between the negativesequence and positive sequence current.The values measured can be accessed locallyvia the user interface on the relay front panelor remotely via the communication interfaceof the relay. The values can also be accessedlocally or remotely using the web-browserbased user interface.7. Disturbance recorderThe relay is provided with a disturbancerecorder featuring up to eight analog and 32binary signal channels. The analog channelscan be set to record either the waveform orthe trend of the currents and voltage measured.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 relay signals, e.g.the start or trip signals of the relay stages, orexternal blocking or control signals. Binaryrelay signals such as a protection start ortrip signal, or an external relay control signalover a binary input can be set to trigger therecording.8. Event logTo collect sequence-of-events (SoE) information,the relay incorporates a memory witha capacity of storing 50 event codes with associatedtime stamps. The event log facilitatesdetailed pre- and post-fault analyses of feederfaults and disturbances.The SoE information can be accessed locallyvia the user interface on the relay front panelor remotely via the communication interfaceof the relay. The information can further beaccessed, either locally or remotely, using theweb-browser based user interface.9. Recorded dataThe relay has the capacity to store therecords of four fault events. The records enablethe user to analyze the four most recentpower system events. Each record includesthe current and voltage values, the start timesof the protection blocks, time stamp, etc. Thefault recording can be triggered by the startsignal or the trip signal of a protection block,or by both. The available measurement modesinclude DFT, RMS and peak-to-peak. In addition,the maximum demand current with timestamp is separately recorded.ABB

Feeder ProtectionREF6151MRS75637910. Circuit-breakermonitoringThe condition monitoring functions of therelay constantly monitors the performanceand the 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.11. Trip-circuitsupervisionThe trip-circuit supervision continuouslymonitors the availability and operability ofthe trip circuit. It provides open-circuit monitoringboth when the circuit breaker is in itsclosed and in its open position. It also detectsloss of circuit-breaker control voltage.12. Self-supervisionThe relay’s built-in self-supervision systemcontinuously monitors the state of the relayhardware and the operation of the relaysoftware. Any fault or malfunction detectedwill be used for alerting the operator. A permanentrelay fault will block the protectionfunctions of the relay to prevent incorrectrelay operation.13. Access controlTo protect the relay from unauthorized accessand to maintain information integrity, therelay is provided with a four-level, role-basedauthentication system with administratorprogrammableindividual passwords for theviewer, operator, engineer and administratorlevel. The access control applies to the frontpaneluser interface, the web-browser baseduser interface and the PCM600 tool.14. Inputs and outputsDepending on the standard configurationselected, the relay is equipped with threephase-current inputs and one residual-currentinput for non-directional earth-fault protection,or three phase-current inputs, one residual-currentinput and one residual voltageinput for directional earth-fault protection.The phase-current inputs are rated 1/5 A.Two optional residual-current inputs areavailable, i.e. 1/5 A or 0.2/1 A. The 0.2/1 A inputis normally used in applications requiringsensitive earth-fault protection and featuringcore-balance current transformers. The residual-voltageinput covers the rated voltages100, 110, 115 and 120 V.The phase-current input 1 A or 5 A, the residual-currentinput 1 A or 5 A, alternatively 0.2A or 1 A, and the rated voltage of the residualvoltage input are selected in the relay software.In addition, the binary input thresholds18…176 V DC are selected by adjusting therelay’s parameter settings.All binary input and output contacts arefreely configurable with the signal matrix toolin PCM600.ABB

CommunicationThe relay supports two different communicationprotocols: IEC 61850 and Modbus®. Operationalinformation and controls are availablethrough these protocols. However, somecommunication functionality, for example,horizontal communication between the relays,is only enabled by the IEC 61850 communicationprotocol.The IEC 61850 communication implementationsupports all monitoring and controlfunctions. Additionally, parameter setting anddisturbance file records can be accessed usingthe IEC 61850-8-1 protocol. Further, the relaycan send and receive binary signals fromother relays (so called horizontal communication)using the IEC61850-8-1 GOOSE profile,where the highest performance class with atotal transmission time of 3 ms is supported.The relay can simultaneously report to fivedifferent IEC 61850-8-1 clients.All communication connectors, except for thefront port connector, are placed on integratedoptional communication modules. The relaycan be connected to Ethernet-based communicationsystems via the RJ-45 connector(100BASE-TX) or the fibreoptic LC connector(100BASE-FX). If connection to a RS-485 networkis required, the 10-pin screw-terminalconnector can be used.Modbus implementation supports RTU, ASCIIand TCP modes. Besides standard Modbusfunctionality, the relay supports retrievalof time-stamped events, uploading of disturbancefiles and storing of the latest faultrecords. If a Modbus TCP connection is used,five clients can be connected to the relaysimultaneously.When the relay uses the RS-485 bus for theModbus RTU/ASCII communication, bothtwo- and four wire connections are supported.Termination and pull-up/down resistorscan be configured with jumpers on the communicationcard so external resistors are notneeded.The relay supports the following time synchronizationmethod with a time-stamping resolutionof +/-1 ms:Ethernet based:• SNTPSupported communication interfaces and protocols100BASE-TXRJ45100BASE-FX LCIEC 61850-8-1 • • -MODBUS RTU/ASCII - - •MODBUS TCP • • -RS-48510ABB
