Automatic Fault Identification Method for Substation Operation and Maintenance Based on Short-Circuit Current
To improve the accuracy of fault identification in substation operation and maintenance,a method for automatic identification of substation operation and maintenance faults based on short-circuit current is proposed.Eliminate noise and outliers in current data,analyze the changes in short-circuit current signals before and after faults,use short-circuit current characteristic data to mine fault information in current signals,and achieve automatic identification of substation faults.The results show that the method proposed in this article can determine the occurrence of three-phase short circuit faults in line 7 of the 220 kV substation and single-phase short circuit faults in output line 2.The identification effect of this method is good.
