| 摘 要： | 元件的故障率研究是电力系统可靠性分析中的一个重要环节。综合考虑影响故障率的三个因素，建立了元件故障率的故障树模型。并用下行法求出了该故障树的最小割集，给出了计算方法。通过对2006年宁夏电网下属银川供电局和石嘴山供电局的输变电设施的停运统计，运用故障树法对变压器、架空线和断路器三类主要输变电设施进行了故障率计算与分析，提出了影响宁夏电网故障率高低的因素，为降低输变电设施的故障率提供有益的依据。

| Abstract: | Failure rate analysis of components is an important aspect of reliability of power system.By taking into account three aspects of failure rate,fault tree model of components' failure rate is established.Minimum cut set and solution of the fault tree are presented in the paper.By gathering outage data of Yinchuan and Shizuishan power supply bureau of Ningxia power system in 2006,the failure rate of transformer,overhead line and breaker,which are the three main power transmission facilities,is effective calcu... |
