During the operation of the power system, there is often a set of auxiliary protection systems for monitoring the operation status of the power system. It is mainly used to detect and respond to specific faults or abnormal conditions to enhance the reliability of the main protection system. The additional protection relay is one of the auxiliary systems. Its main functions include: (1) Fault detection, identifying abnormalities such as short circuit, overload, and ground fault; (2) Signal output: After detecting a fault, it sends a signal to the circuit breaker or control system to trigger the protection action; (3) Backup protection: Provide an additional layer of protection when the main protection fails.
