Background

It is inevitable that a power system fails, and after the failure occurs, the current and voltage changes of elements in the power system are influenced by many factors such as the type of the failure, the location of the failure, the network structure and the real-time power flow, and multiple failures may occur. Therefore, it is very important to accurately and effectively monitor the faults of the power system, wherein the monitoring of the microcomputer protection device in the power system is more critical.

And (4) testing whether the protection logic and setting value of the microcomputer protection device are reasonable one by one, triggering the protection device through a microcomputer comprehensive protection calibrator, and checking whether the tripping signal and the alarm model are correct or not. The current method is not only low in efficiency, but also low in precision, and is difficult to realize the on-line monitoring of the faults of the power system.
