Based on S-Transformation Single-Phase Transient Faults and Permanent Fault Identification

Abstract:

For both ends of the reactor with a parallel transmission lines, a method using Fault-phase voltage of low frequency component to Discrimine of the fault nature in Recovery voltage phase. In this method, different frequency bands is obtained by S-transform for Recovery phase of the faulted phase voltage capacity ,compare the low frequency part , in advance , determining the nature of the fault. Through theoretical analysis and a large number of verification of PSCAD, This method can effectively distinguish the fault type.
