A relay protection test method and system, the relay protection device test input is divided into conventional analog input and digital input, digital input is divided into SV9-1, SV9-2, IEC60044-8, etc.; GOOSE switch input. The present invention carries out process design by introducing concepts such as mapping and interval, and completely decouples test configuration files and test data files, which solves the problem of rapid multiplexing of relay protection device test engineering data; secondly, the logic function of the test device, test configuration Documents, test data files, test reports and other data are ingeniously integrated to realize the actual relationship between the three-level management mode of the test engineering project and the data; at the same time, it provides effective control of single test and continuous test; according to test requirements, it provides gradual changes Test, manual test, oscillation test and other functions; this provides the feasibility for test engineers to quickly and efficiently test the logic function of relay protection devices.
