In view of the low automatic test degree of currently operating smart substations

a scheme for the implementation of smart substation bay level equipment automatic test system is put forward. The automatic test system hardware architecture is described and the main functions of software functional modules and their implementing process are discussed from the angle of software function. For difficult problems in automatic generation of the test cases

abnormality simulation and multi-device testing in the implementing process

detailed workshops have been held and solutions are given. The system has successfully been applied to the smart substation bay level equipment research and development by XJ Electric Co. Ltd..
