A Practical Method for Multi-stage Fault Location of Distribution Network with Incomplete Measurement

Abstract

This paper is to propose a practical method for two-step fault location of distribution network with incomplete measurement. In the first step, the Ant Colony Optimization Algorithm (ACO) which is applied for location in measurement areas is used to locate in the whole networks. In the second step, the theory of rough set is used, which can locate faults in non-measurement areas. This paper is proposed a calculation flow for location model, and a 10kV distribution system of Hangzhou was used for simulating and verifying that the proposed method was effective.
