A New Practical Method for Fault Section Estimation in Distribution System
Abstract:
Accurate locating of fault in power distribution system (PDS) can significantly improve the reliability indices. In this paper، a new simple and practical method is proposed for estimating the section and distance of fault in PDS. In the proposed method، at first the protective devises are allocated and then specially set in such a way that they are coordinated and the unique current pattern is generated at the beginning of feeder for fault in each section. For approving and analyzing the accuracy of the proposed method، the method is tested on two test feeders and one real feeder of Bushehr Distribution Company under different fault conditions. Also، in the real test system two actual faults are applied and the section of fault is correctly determined by the proposed method.
