    Abstract: Most metro medium-voltage power supply systems use large district power supply structures.When the system fails, the cooperation between the protections is rather important. From the perspective of the test of the subway protection device, the protection configuration and test of the large district power supply system are analyzed, and the protection cooperation plan, main protection principles, test items and test methods of important test items in the case of power supply system failure are listed, so as to ensure the rationality of the subway system protection configuration and the correctness of the protection function realization.
    Key words: metro power supply system; protection configuration; protection test
