摘　　要：高比例可再生能源的大规模接入促使配电网向着主动配电网(ADN)的方向转型,大量的信息设备建设扩大了主动配电网的整体规模,提升了信息处理效率,但同时也使得系统安全可靠运行的问题变得更加突出。本文提出考虑老化效应的混合通信网络主动配电网可靠性评估方法,首先采用失效模式与效应分析方法建立信息网络与配电网络间的故障关联模型,其次利用设备性能参数建立信息设备与物理设备的威布尔分布老化失效模型,最后通过序贯与非序贯蒙特卡洛相结合的仿真方法对系统可靠性进行评估。其结果可为未来主动配电网的运行维护提供有力的技术支撑。The large⁃scale access of high proportion of renewable energy has promoted the transformation of the dis⁃tribution network to the active distribution network(ADN),and a large number of information equipment construc⁃tion has expanded the overall scale of the active distribution network and improved the efficiency of information pro⁃cessing,but at the same time,it has also made the problem of safe and reliable operation of the system more promi⁃nent.This paper proposes a risk assessment method for smart distribution network of hybrid communication network considering aging effects.Firstly,the failure mode and effect analysis method is used to establish the fault correla⁃tion model between the information network and the distribution network,and then the Weibull distributed aging failure model of information equipment and physical equipment is established by using equipment performance pa⁃rameters.Finally the system reliability is evaluated by the simulation method combining sequential and non⁃sequen⁃tial Monte Carlo.The result can provide strong technical support for the operation and maintenance of active distri⁃bution networks in future.
