摘　　要：建立了架空系统供电可靠性评估模型,分别以架空主干馈线故障和柱上开关故障为研究场景,在馈线满足N-1和不满足N-12种情形下,运用集中式馈线自动化故障处置原理,分析并推导了架空主干馈线故障和柱上开关故障时的户均停电时间计算公式。特别是针对“二遥”和“三遥”终端混合配置情形,枚举“二遥”和“三遥”终端不同数量、不同位置的配置方案,详细分析故障处理过程,推导得出基于“二遥”和“三遥”终端配置数量的架空系统故障平均停电时间计算公式。最后,以某架空区域配电自动化终端建设为例,对研究成果进行了应用。In this paper,the reliability evaluation model of the overhead system power supply is established and the overhead backbone feeder fault and the on-column switch fault are taken as the research scenarios respectively.Under both the condition that feeder meets N-1 and the condition that the feeder does not meet N-1,using the centralized feeder automatic fault handling principle,the formula for calculating the average power outage time of overhead main feeder faults and on-column switch faults is analyzed and derived.Especially for the mixed configuration of"two remote"and"three remote"terminals,the configuration schemes of different numbers and locations of"two-remote"and"three-remote"terminals are enumerated,the fault processing process is analyzed in detail,and the average outage time of feeder system based on the number of"two-remote"and"three-remote"terminals is deduced.Finally,with the construction of distribution automation terminal in an overhead area as an example,the research results of this paper are applied.
