Self-triggering Fault Self-healing Test Based on Equivalence Class Division

Aiming at the problems of incomplete testing of fault types, long fault cycle of point-by-point testing, and large test manual workload during the commissioning test of the fault self-healing function of the distribution network, a self- triggered fault self-healing test based on equivalence class division of fault points is proposed. Through model cross- section data restoration, automatic triggering of fault action equipment signals, and automatic verification of processing strategies, the automatic triggering, analysis and verification of faults at fault points are carried out. This method has the advantages of improving the test efficiency before the fault self- healing function is put into operation, comprehensive fault case test, reducing the manual simulation of fault action signal and manual judgment of test results, and improving the work efficiency.
