Abstract

The invention relates to a relay protection test method and a system based on the IEC61850 digital tester and belongs to electric energy test technical field. The test business is added in the test case script, one business is corresponding to one node of the test case script, the user can edit the test content in the test case script and set the end condition, the tester can execute the test process while the user transmits the command for starting the test for the edited automatic test case. The test process and the test method are improved via the quantity loaded curing principle, numerous experiments have proved that the automatic test method can effectively save the work time for the test person and raise the test reliability and efficiency.

Description

technical field [0001] The invention relates to a relay protection testing method and system based on an IEC61850 digital tester, belonging to the technical field of electric energy testing. Background technique [0002] As technologies such as electronic transformers, intelligent primary equipment, and microelectronics technology become more mature, intelligent substations have become a development trend, and the application of intelligent electronic equipment is becoming more and more extensive. In the test of IED equipment, the test The instrument conducts performance tests by inputting current and voltage to the device under test. Repeated operations occupy most of the test content, and the test process takes up a lot of manpower and material resources. In addition, the introduction of digital network technology puts forward certain 61850 technical standards and regulations for testers. Microcomputer protection verification requires test equipment to be able to simulate ...
