摘　　要：随着中国经济由高速增长阶段转向高质量发展阶段,全社会对电力的依赖程度越来越高,广大用户对供电可靠性提出了更高的要求。在分析复杂配电网网络结构的基础上,提出了一种将含有分支馈线的复杂配电网转化为典型接线模型的方法;在详细分析系统各供电可靠性指标的基础上,提出了一种基于典型接线模式的供电可靠性算法,并依托某城区配电网模型进行了仿真验证,仿真结果表明该算法的有效性。As the economy in China shifts from a high-speed growth stage to a high-quality development stage,the whole society is increasingly dependent on electricity,and users have put forward higher requirements for power supply reliability.Based on the analysis of the network connection of complex distribution network,a simplified method for transforming a complex distribution network with branch feeders into a typical wiring model is proposed.Based on a detailed analysis of the reliability indicators of the system,a power supply reliability algorithm based on typical wiring modes is proposed.And the simulation verification is carried out based on the distribution network model of an urban area.Simulation results show the effectiveness of the proposed algorithm.
