Application examples


RED615 Why line differential protection?

Case Overcurrent protection challenges SolutionFault current contribution from more than one source (direction)

Selective protection scheme still required RED615

Protection co-ordination Protection co-ordination based on definite or inverse time delays might result in too high accumulated time delays within the chain of protection devices

RED615

Varying fault current levels Difficult to find protection setting parameters that would suit all cases RED615

Load currents magnitudes close to fault current levels

Difficult to separate fault conditions from normal loading RED615



RED615 Line differential protection application examples

Parallel feedersLooped feeder constructionDoubled feeders

Two interconnected feeders between a primary substation

Reserve connections or meshed type of network

Distributed generationPower generation at the remote end of the feeder

Weak grid supplying relatively long distribution lines



RED615 Unit protection with overcurrent back-up protection

The phase currents of CT core #2 are summated externally to the IED, and used as CT supervision (MCS3I) reference current

The two lowest overcurrent stages are used for remote back-up protection

The two highest overcurrent stages are blocked under normal conditions and released in case of protection communication failure

Binary signal transfer, 8 signals for user definable purpose (BST)

Protection communication supervision (PCS)


Standard configuration “A”


RED615 Unit protection with directional earth-fault protection


Standard configuration “B”

The cable CT I0 input is used for directional earth-fault protection and for CT supervision (MCS3I) reference current

Non-directional earth-fault protection stage, based on calculated I0,, for cross-country earth-fault protection

Auto-reclosing option for overheadlines

Thermal overload protection for feeders


Two highest overcurrent stages are blocked under normal conditions and released in case of protection communication failure




RED615 Unit protection with non-directional earth-fault protection


Standard configuration “C”

The fourth CT (I0) input is used for non-directional earth-fault protection and for CT supervision (MCS3I) reference current

The same phase CT cores can be used for main protection and for earth-fault protection (external summation), but in that case the CT supervision shall not be used

Functionality highlights


RED615

Stabilized low stage and instantaneous high stageThe protection algorithm calculation is performed both in the local and the remote IEDDirect intertrip between line ends ensures simultaneous tripping of the local and the remote CB Detection (blocking) for inrush conditions based on the second harmonicPossibility to introduce either definite or inverse time delay for the stabilized low stage

Line differential protection



RED615

Small tapped loads can be included inside the LD protection zoneLD protection selectivity towards the protections on the LV-side of the power transformer can be achieved by introducing a time delay for the low set stageFaults on the feeder with low fault impedance (=> high fault current) cleared by the high set stage

Communication


615 series Designed for IEC 61850

Native support for IEC 61850 communication between devices in substationsIEC 61850 enables “GOOSE” (GenericObject Oriented Substation Event) horizontal communication between IEDsRED615 can simultaneously report events to five different clients on the station busRED615 also supports:

Modbus TCP/IP and RTU / ASCII DNP3 TCP/IP and serial IEC 60870-5-103



615 series IEC 61850 GOOSE communication

Standardized horizontal communication enables interoperability between any IEDs supporting GOOSE communicationUsed for transmitting binary process data to peer IEDs within a substationEthernet technology offers a fast and reliable station bus for the transfer of dataThe publisher-subscriber principle allows the IEDs to send and/or receive time critical data

Station Automation COM600

Station bus IEC 61850

Network control centreMicroSCADA Pro



615 series GOOSE communication benefits

Expandability and flexibility:Flexible modifications without changing the wiring between the IEDsNo IED I/Os are needed for the transer of data between the IEDsReduced wiring between the IEDsPossible to add functionality like interlocking schemes between the cubicles in existing switchgear (retrofit)

Supervised data transfer (connection and data quality)RED615 meets the GOOSE performance requirements for tripping applications in distribution substations, as defined by the IEC 61850 standard



RED615

On detecting a fault on the outgoing feeder IED B sends a trip command to CB “B” and initiates the CB failure protection function CB “B” fails to openThe CB failure protection function of IED B sends a trip command to IED A using GOOSEThe use of GOOSE communication eliminates the need for dedicated wiring CB failure protection can be added without renewing the wiring and with minimum disturbance to the process
