摘要：In a certain power supply company, its repairing time for distribution network fault declined sharply in the year of 2017. Based on the data of work orders, this paper uses approaches, such as cluster analysis, comparison and trend analysis, to analyze the monthly trend, regional distribution and fault type with regard to repairing time of distribution network fault. The analysis has shown that there are problems like low resistance of distribution network equipment to lightning, weakness in the structure of rural grid, long repairing time for low-voltage fault and low level of automation for distribution lines. In the meantime, this paper provides advice accordingly, aiming to serve as reference for repairing efficiency enhancement regarding distribution network fault in the company.
