Overview: The ABB REG670 1MRK002247-BGr00 is a comprehensive protection and control IED designed for generators and generator-transformer units. It integrates main and backup protection, measurement, synchronism check, excitation control, and disturbance recording into a single platform. It addresses coordination, sensitivity, and fault-localization challenges on generation assets. Power-plant protection engineers, I&C teams, and generation-facility operators gain high-speed, dependable protection with reduced wiring and cabinet space.
Key Functions:
- High-Speed Generator Differential Protection: Detects internal winding faults with typical operating time ≤15 ms to minimize equipment damage and reduce outage duration.
- Comprehensive Stator and Rotor Ground Protection: 100% coverage via third-harmonic and injection methods, identifying high-resistance faults that overcurrent protection may miss.
- Disturbance Recording and Event Analysis: Captures COMTRADE waveforms, 10 s pre-fault, and 100+ fault records with millisecond-stamped event logs for post-incident root-cause analysis.
- Flexible Communication and Time-Sync: Full IEC 61850 including GOOSE (<3 ms latency), plus multiple protocols and time-sync options for new and retrofit substations.
- Integrated Control and Automation: Includes breaker control, auto-synchronization, excitation regulation, and user-programmable logic, reducing need for separate controllers.
