摘要: 配网故障抢修效率的分析能够及时反映配网运行和管理现状,故障修复时长是故障抢修效率的衡量标志。为此,针对某供电公司2015年配网故障修复时长大幅下降的现象,以统计数据为基础,通过聚类、趋势等分析方法,对其进行月度趋势、地域分布和故障类型分析,透过分析结果查找配网运行和管理方面存在的问题。分析表明,该公司存在配网设备抗击雷电能力较弱、农网架构比较薄弱、低压故障修复时长比较突出、配电线路自动化程度较低等问题。最后,根据问题给出针对性建议,期望对该供电公司进一步缩短配网故障修复时长起到帮助和借鉴作用。

关键词: 配电网, 修复时长, 统计数据, 故障类型

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
