Abstract

The invention provides a transformer substation relay protection device constant value conformance automatic test method and system, and the method comprises the steps: automatically calculating and selecting a constant value test sequence, needing to be tested, of a protection device, carrying out the automatic testing in sequence, avoiding the manual input of a tester, and being high in automation degree. The constant value test time is greatly reduced, and the constant value test efficiency of the relay protection device is greatly improved; a uniform valuing algorithm or a random valuing algorithm can be flexibly adopted to select a constant value setting value from all constant value setting values for testing, so that the test coverage degree is improved, and the test sufficiency isensured; repeated labor of testers is reduced, and the testers can better tease the test process and analyze the test result.

Description

technical field [0001] The invention relates to the technical field of power distribution automation, in particular to a method and system for automatically testing the compliance of the fixed value of a substation relay protection device. Background technique [0002] In recent years, smart substations have developed rapidly in the field of substation automation. As an important part of smart substations, relay protection devices can monitor the operation of substations in real time and predict potential risks of the power grid. When the power grid fails, it can quickly locate, isolate the fault and restore power supply in time. Therefore, the relay protection device plays an important role in ensuring the safe operation of the power system. The relay protection setting value is the basis for ensuring the correct operation of the protection device. Therefore, before the relay protection device is put into power grid operation, its setting value compliance should be fully t...
