ABB Relion 615 Series Communication and Control Architecture
The ABB REM615 integrates IEC 61850 communication functions for substation automation systems. It exchanges protection signals and control data through GOOSE messaging and supports Sampled Values communication for digital process interfaces.
The relay uses configurable binary inputs and outputs to execute motor control commands and protection trip circuits. In addition, its withdrawable construction allows technicians to remove the relay module from the housing for inspection and testing without changing the panel wiring.
For ABB industrial control platforms, the REM615 supports deterministic network communication concepts such as IEC 61850 Ethernet-based data exchange. The unit also supports firmware flash compatibility within the defined Relion 615 hardware configuration, which allows controlled software maintenance procedures.
Frequently Asked Questions
Q: Does the ABB REM615 support hot-swappable replacement during operation?
A: The REM615 uses a withdrawable plug-in design for maintenance access. The system operator must follow approved protection system isolation procedures before removing the relay module.
Q: Which motor protection measurements are available through the relay inputs?
A: The REM615 measures three-phase currents, residual current, three-phase voltages, and residual voltage. Optional RTD modules provide temperature measurement inputs for motor condition supervision.
Q: Which communication protocols can the REM615 use for substation integration?
A: The relay supports IEC 61850 Edition 1 and Edition 2, GOOSE messaging, Sampled Values, Modbus, DNP3, and IEC 60870-5-103 communication protocols.
Field Installation Guidelines
- Install the REM615 in a suitable protection panel with correct mechanical support for the withdrawable relay housing.
- Verify current transformer and voltage transformer wiring before energizing the protection circuit.
- Separate communication cables from high-voltage power wiring to reduce electromagnetic interference.
- Connect cable shields according to the site grounding design and IEC 61850 network requirements.
- Check binary input polarity and output contact wiring before commissioning.
- Confirm Ethernet network settings, time synchronization configuration, and IEC 61850 communication parameters before system operation.
- Perform protection function testing after installation, including thermal overload, overcurrent, ground fault, and motor start supervision functions.
