AI Technical Summary
In existing technologies, relay protection devices lack real-time monitoring and response capabilities during soft errors, leading to a higher probability of false outputs and failing to guarantee the reliability of the power system and rapid fault handling.
The fault handling program of the relay protection device is decomposed and reconstructed into two independent logic processing programs. An entry confirmation variable and an anomaly judgment logic for positive and negative code output are set. Errors are blocked in real time through XOR operation and anomaly judgment logic, and program and parameter consistency verification and recovery processing are performed.
It enables real-time blocking and system recovery when a soft error occurs in the relay protection device, ensuring the reliability of the power system and the reliability of rapid fault handling, and improving the accuracy of anomaly detection and the continuous availability of the system.
