关 键 词：Distribution network Neural network Fault location Wavelet analysis
摘 要：The distribution network own characteristics such as:complicated topology and variable operation mode,so the fault location problem of the distribution network has not been *** on the analysis of the single-phase ground of the system,this paper combines wavelet analysis and neural *** method not only utilize time-frequency features and zoom capabilities of wavelet analysis in order to pick up the characteristics of component,but also take advantage of the capacity of non-linear fitting of neural network. These studies establish correspondence between characteristics of component and fault location,and resolve successfully the problem of the precision positioning,the thought of fault location has fully theoretical *** data of EMTP/ATP simulation shows that the scheme has high precision,adaptable and reliable performance.
