摘　　要：配电网直接影响到用户体验,随着馈线自动化的发展,评估馈线自动化下的配网可靠性评估方法十分重要。选择了解析法思路的可靠性评估方法;对负荷点故障类型进行分类;在分类的基础上,进行故障类型的确定;建立可靠性评估模型进行相关的指标计算。最后通过某市的环网组线验证了该可靠性评估方法的可操作性,研究成果可计算出改造后暂未有运行数据的可靠性指标,对配电网的规划运行人员在相关决策上具有一定的参考意义。Distribution network directly affects user experience.With the development of feeder automation,it is very important to evaluate the reliability evaluation method of distribution network under feeder automation.The reliability evaluation method based on analytical method was selected.The fault types of load points were classified.The fault type was determined on the basis of classification.A reliability evaluation model was established to calculate the relevant indicators.The feasibility of the reliability assessment method was verified through the loop grid assembly line of a city.The research results can calculate the reliability index of the operational data after the transformation,which has certain reference significance for the planning and operation personnel of distribution network in making relevant decisions.
