Fault Location of Transmission Line based on Discrete Wavelet Transforms

摘要：

　　In this paper,a novel method is investigated to detect short-circuit fault signal transmission lines in strong noise environment based on discrete wavelet transform theory.Simulation results show that the method can accurately determine the fault position,can effectively analyze the non-stationary signal and be suitable for transmission line fault occurred after transient signal detection.Furthermore,it can effectively eliminate noise effects of fault signal so as to realize the transmission lines of accurate fault.
