The Fault Location Method for Transmission Line in Distribution System with Time Series Wavelet Neural Network System

摘要

A scheme of high accurate fault location with high frequency in fault transient signals on non-direct-ground neutral system is proposed. The wavelet neural networks models proposed before are not suited to the time series analysis of fault location, so the general concept of wavelet neural networks are introduced, and the time series wavelet neural network is proposed for discrete signal analysis. Then according to the characteristic of fault transient signals, the adaptive time series wavelet neural network is adopted for fault location on non-direct-ground system, simulation results illustrate the efficiency and practice of the method proposed in this paper.
