Fault Location for Resonant Grounded System Based on Zero-Sequence Current Increment Method

Abstract—In order to deal with the problem of single-phase earthing fault in resonant grounded system, a new method of fault line and segment selection was proposed using zero-sequence current increment through analyzing the line fault on substation outlet and the change of the fault component of zero-sequence current. The zero-sequence current in the line will change when the inductance of arc-suppression coil is changed. The method determines the fault location based on the characteristic of the change in the line. The effects of resistance grounding can be eliminated by converting zero-sequence currents to the same voltage. Matlab simulation experiments verify the correctness and validity of the method.

Index Terms—Resonant grounded system, single-phase earthing fault, zero-sequence current increment method, fault location, arc-suppression coil.
