[0002] Relay protection device is an important equipment to ensure safe and stable operation in power system, and its performance directly affects the stability and safety of power system.

[0003] However, in the prior art, the verification of relay protection devices mainly relies on manual operation, including wiring, logic verification, parameter adjustment and verification report compilation. This method requires operators to have high professional skills, especially when facing protection devices with complex functions and diverse logics, it is even more difficult for young employees to complete it independently. In addition, the number of protection devices in power stations is usually large, the verification workload is large, and the manual operation is time-consuming, which makes it difficult to meet the tight schedule requirements during equipment maintenance. During the manual verification process, due to the need to add voltage and current and frequently modify the set value parameters, control words and logic configuration, it is very easy to cause safety problems due to operational errors, such as electric shock or equipment damage. At the same time, after the verification is completed, the original parameters, set values ​​and logic need to be manually checked, and the verification report needs to be manually filled in. This method is very prone to omissions or errors when the data volume is large. The root cause of these problems is that the existing verification method lacks automation support, has low work efficiency, insufficient accuracy and high operational risks.
