摘要
架空输电线路的运行状态直接影响整个电力系统运行的可靠性,为真正实现线路状态检修,该文采用蒙特卡洛方法和故障树分析方法,结合MATLAB软件对架空输电线路进行故障树-蒙特卡洛定量可靠性分析,得出通道环境是架空输电线路中最薄弱的环节,在架空输电线路维护和检修中应重点关注。通过合理设计来降低通道环境风险概率,从而提高架空输电线路的可靠性,对正确评估运行中架空输电线路的可靠性水平具有重要的理论意义和现实价值。
The operating status of the overhead transmission lines directly affect the reliability of the entire power system. In order to truly achieve its status maintenance,the Monte Carlo method and the fault tree analysis method are adopted in this paper to perform the reliability analysis of the overhead transmission line through the MATLAB software. And it is concluded that the channel environment is the weakest part,which should be paid more attention to in the maintenance and examination of the overhead transmission line. Reasonable design can reduce the probability of environmental risk and improve the reliability of overhead transmission lines,which has important theoretical and practical value for correctly assessing the reliability level of overhead transmission lines in operation.
