The ABB REC670 1MRK002814-AB bay control device, part of the Relion® series, is primarily used for controlling, protecting, and monitoring various bay types in power systems. The following is a detailed description:
Features
Multiple protection functions: It offers instantaneous phase and ground overcurrent protection, four-stage directional or non-directional time-delay phase and ground overcurrent protection, thermal overload protection, and two-stage undervoltage and overvoltage protection, providing comprehensive protection for power equipment.
Flexible control modes: It enables remote (SCADA station-level) control via IEC 61850-8-1 station bus data communication, as well as local operation via the device's front-panel human-machine interface (HMI). A single measurement, control, and protection device can control a single electrical bay or multiple bays simultaneously.
Multiple communication protocol support: Support for IEC 61850-8-1 Ed1 or Ed2, DNP3, and other protocols facilitates communication and integration with other devices or systems, enabling rapid data transmission and interaction. Redundancy: Built-in PRP (Parallel Redundancy Protocol) functionality supports star or ring bus architectures, improving system reliability and stability.
Synchronism Check: The synchro-check function blocks fault recording and fault closing during a single system fault. It also performs independent post-fault analysis to ensure the circuit breaker closes at the appropriate time.
