The Research of C-Type of Traveling Wave for Fault Location in Distribution Network

Abstract:

On the basis of analysis on difficulty of a single phase grounding fault locating in distribution network, a fault location method using C-type of traveling wave is put forward. The C-type of traveling wave location method is off-line. This location method can not be affected by the signal intensity of traveling wave when the fault is taking place and would be used repeatedly. As a result, the measure accuracy is guaranteed. Through the simulation to traveling wave’s process of reflection and refraction by ATP, the result what simulation experiment shows by putting up model of 10kV line with 3 branches single phase grounding fault, we can compare waveform of the normal phase and the fault phase to find the first waveform distortion point and determine the fault location. The fault location precision meets accuracy requirements, so it is feasible to locate the fault by using C-type of traveling wave location method.
