摘　　要：供电可靠性每增加一个百分点,供电企业为改善供电可靠性而增加的费用也将急剧增加。引用了国外对配电系统可靠性的一些参考指标及工程计算方法,一个基本辐射型配电系统为算例,分别介绍了配电系统实施自动化的主要手段———电缆故障指示器及配电管理系统,从经济的角度对可靠性提高的影响进行了计算与分析。指出了当前实施配电自动化系统应采用的主要手段及理想的投资切入点。The power supply enterprise will have a sharp increase on its cost on reliability improvement of power supply, when the reliability of power supply is increased by one percent. Some abroad reference idexes and engineering calculation methods are recommended in this paper. Meanwhile,through a calculation case of a basic radiation distribution network, and from the perspective of economy, the paper analyses and calculates the influence of the main means of distribution network automation, i.e. cable fault indicator(CFI) and distribution management system(DMS)on reliabilty improvement. Also, it puts forward the main means to realize distribution network automation and the ideal investment cut-in point.
