摘　　要：针对集中式FTU控制的馈线自动化,提出了一种可靠性分析模型。该模型考虑“三遥”开关的故障概率,根据集中式馈线自动化系统的工作逻辑、开关元件的自动化程度和各种开关的动作特性,将馈线自动化动作过程中的配电网分成6个区域,在可靠性分析模型中在故障定位、隔离、恢复3个阶段统计6个区域的参数,最终得到系统的可靠性指标,并根据提出的计算模型讨论动作策略、联络开关送电顺序、智能开关配置方式对系统可靠性的影响。该计算模型在供电方式设计、开关配置、供电策略制定等方面有实际参考意义。This paper presents a reliability analysis model for feeder automation based on centralized FTU control.The model considers the failure probability of"three remote"switches.According to the working logic of the centralized feeder automation system,the degree of automation of configuration switch elements and the action characteristics of various switches,the distribution network in the process of feeder automation action is divided into six areas.In the reliability analysis model,the parameters of six areas are counted in three stages of fault location,isolation and recovery,and finally the reliability index of the system is obtained.According to the proposed calculation model,this paper discusses the influence of feeder automation,action strategy,power transmission sequence of interconnection switch and configuration mode of intelligent switch on system reliability.The reliability calculation model has practical reference significance in the design of power supply mode,switch configuration,power supply strategy,etc.
