A fault location method for Distribution network with DG system based on amplitude and phase of the current

With large scale Distributed Generation (DG) connected to the distribution network, the topology structure of the distribution network has become more complex. Moreover, it brings some negative effects to the traditional fault location method. In order to achieve a more efficient and accurate fault location method, this paper proposed a new fault location method which is based on Amplitude and Phase of Current for the Distribution network with DG. The proposed method is not only simple and easy to implement, but also can accurately locate the fault. Simulation results verify that this method is effective and feasible.
