The utility model discloses a standardized test operating system for relay protectors and relates to the field of relays. The standardized test operating system comprises a test plan module and a test module. After the test plan module is started, the test plan module controls the test module automatically, corresponding test plans in the test plan module are started according to functions of the test module, the test module executes tests according to the corresponding test plans, and the test plan module sends prompt information and record test data during test processes of the test module. After tests are finished, test reports in uniform format are formed in the test plan module. Requirements of the standardized test operating system to comprehensive quantity of test staff are reduced so that standardization and automation of test methods are realized truly. Since the test reports can be formed automatically once the tests are finished, problems of non-uniform format, waste of time, delay in arranging and filing in manual management of test reports are solved.
