Research on the Fault Location of 35kV Distribution Line

Abstract:

A kind of C-type of traveling wave location method is proposed in this paper. After the single phase grounding fault happened, inject a high voltage narrow pulse signal into the fault phase line and the normal one respectively, collect the reflected signals at detection point, make this two signal waveforms subtract and find the corresponding time of fault point characteristic wave, calculate the fault distance by using location equation. Conduct wavelet packet decomposition and reconstruction on the waveform subtraction signal, judge the fault section by comparing energy changed values of node characteristic waves.
