RED615 is ABB Relion ® The intelligent electronic device (IED) for line differential protection and control under the 615 series is designed specifically for public utilities and industrial power systems. Its core application is the protection and control of overhead lines and cable feeders, and it is suitable for ring and mesh power grids with or without distributed generation. Its core characteristics can be summarized as:
Integrated protection function: with "line differential protection" as the core main protection, while integrating backup protection such as overcurrent, ground fault, circuit breaker failure, etc., to meet the requirements of modular protection;
Standardized communication: Deeply compliant with the IEC 61850 standard, supporting GOOSE messages (transmission delay ≤ 3ms), IEC 60870-5-103, Modbus ®、 DNP3 and other protocols, adapted for interconnection of substation automation systems;
Flexible configuration capability: Provides 3 standard configuration solutions, supports customizing signal logic through PCM600 tool, and adapts to different grounding methods (isolated neutral, resistance grounding, compensation grounding, direct grounding) of the power grid;
Full lifecycle support: Equipped with a complete documentation system (engineering, installation, debugging, operation and maintenance manuals), supporting local (LHMI) and remote (WHMI) operations, simplifying engineering and maintenance processes.
Time synchronization: Line differential protection requires remote station time reference synchronization, which is recommended to be implemented through IEC 61850 or SNTP.
