可靠性成本/价值分析在配电网规划和运行中起着重要的作用。分析中使用的中断成本模型直接影响用于做出加固决策的预测可靠性价值。提出了两种可用于可靠性成本分析的成本模型：平均或聚合模型和概率分布模型。时序仿真技术说明了配电系统的可靠性成本/价值评估使用两个开发的成本模型，并将随时间变化的负载。该技术是用来评估安装横向熔断器，隔离开关和备用电源在测试配电系统的可靠性价值。结果表明，采用平均或汇总模型会导致低估可靠性价值，而概率分布模型方法可能更有意义。
Reliability cost/worth analysis plays an important role in distribution system planning and operation. The interruption cost model used in the analysis directly affects the predicted reliability worth used to make reinforcement decisions. Two cost models are presented that can be used in reliability cost analysis: an average or aggregate model, and a probability distribution model. A time sequential simulation technique is illustrated for distribution system reliability cost/worth assessment using the two developed cost models and incorporating time-varying loads. The technique is used to evaluate the reliability worth of installing lateral fuses, disconnect switches and alternate supplies in a test distribution system. The results show that using the average or aggregate model can result in underestimating the reliability worth, and that the probability distribution model approach may be more meaningful.
