Abstract

Abstract: Analysis of the fault repair efficiency of distribution network can timely reflect the operation and management status of the distribution network. Fault repair time duration is a measure of the fault repair efficiency. According to the fact that the fault repair time of distribution network decreased substantially in a company in 2015, an analysis is made on the fault repair time based on statistical data in terms of monthly trend, regional distribution and fault types by cluster, trend and other analyzing methods, from which the existing problems in the operation and management of distribution network are identified. The results show that the company has several problems such as poor capability in lightning resist of distribution network equipment, weak tower structure of rural power grids, long repair time of low voltage faults and low automation degree of distribution lines. Finally, targeted suggestions are proposed, which may help the company to shorten the fault repair time of distribution network.

Key words: distribution network, repair time, statistical data, fault type
