| 摘 要： | 针对含主电源和一个备用电源的配电网,提出一种快速可靠性评估算法。该算法将配电网分成连接主电源至备用电源的主网络和余下的支网络。先通过元件可靠性指标的逆流传递求支网络各结点的逆流可靠性指标,并用接于主网络各支结点的等效元件替代相应的支网络。再用故障模式影响分析(failure-mode-effect-analysis,FMEA)法计算主网络各结点的可靠性指标和支结点的顺流可靠性指标。然后,通过片可靠性指标的顺流归并求支网络各结点的顺流可靠性指标。综合逆流和顺流可靠性指标即得支网络各结点的可靠性指标。该算法考虑了断路器和分段开关操作时间的差异,它不仅具有FMEA法的准确度,而且计算速度比已有方法快得多。算例仿真验证该方法的有效性。

| Abstract: | A fast evaluating method on distribution system reliability is proposed,aiming at the distribution system with the main supply and an alternative supply. In this method,the distribution system is divided into main and branch networks. At first,the up-stream reliability indices of each point in branch networks are determined by up-stream delivering of each comoponent's reliability indices. Each branch network is replaced by an equivalent component in the main network. Then the failure-mode-effect-analysis (F... |
