In view of the problem of too much manual intervention in the IEC 61850 conformance testing in the smart substation

a closed-loop conformance testing system supporting standard IEC 61850 is proposed. By employing a software platform based on the Qt component + bottom logic analysis dynamic depot and distributed hardware platform based on the DSP+ARM dual-core processor

the system mainly writes the test cases related to the standard IEC 61850 Ed 1. 0 in open source and Python language. Moreover

function interfaces are provided for the convenience of customized definition of a case. The software can automatically execute the test cases to realize full-closed loop in the experiment process

which improves the test efficiency and quality of the test. In the platform test and case part

typical Ed 1. 0 test cases are verified with the actual device as the target. The experimental results show that the test cases can meet the demand of IEC 61850 conformance testing.
