A Composite Fault Location Method of Competitive Neutral Network for Distribution Lines

A method for accurate fault location on a distribution line with branches using the C-type of traveling wave signal and CNN is presented. It integrates the C-type of traveling wave location method with CNN. The aim is to combine different location methods to improve the accuracy of fault location. It has two steps. The first step is determining the fault distance by C-type of traveling wave location method, the second one is locating the fault branch by CNN. Both theoretical analyses and simulation show that this composite location method can be used to determine the single-phase-to-earth fault location accurately in the distribution network.
