Verification method of nuclear power station transformer protection device, server and medium

Abstract

The invention is suitable for the technical field of nuclear power station power transmission and distribution and protection systems, and provides a verification method of a nuclear power station transformer protection device and a server. The method comprises: reading preset protection action information of the protection device; sending a first setting instruction to the protection device; sending a first output instruction to the relay protection tester and receiving a first check value returned by the relay protection tester; if a first difference value between the first verification value and the theoretical action value is smaller than or equal to a first preset error value, generating a first verification result; sending a second setting instruction to the protection device; sending a second output instruction to the relay protection tester, and receiving verification time delay returned by the relay protection tester; if a second difference value between the verification timedelay and the theoretical action time delay is smaller than or equal to a second preset error value, generating a second verification result; and importing the first verification value, the first verification result, the verification time delay and the second verification result into the preset verification report template, so that errors are reduced, and the verification efficiency and reliability are improved.

Description

technical field [0001] The application belongs to the technical field of power transmission and distribution and protection systems of nuclear power plants, and in particular relates to a verification method, a server and a computer-readable storage medium for a transformer protection device of a nuclear power plant. Background technique [0002] Generator transformer group protection system is a relay protection system for large-scale power equipment such as nuclear power generators, main transformers, and factory transformers. The system is cut off to prevent the expansion of power equipment failure accidents. Usually, the generator transformer protection system will configure the corresponding protection device according to the type and quantity of the power equipment. In order to make the protection device operate correctly when the power equipment it protects fails, it is necessary to regularly check the protection device. At present, the traditional calibration method...
