架空输电线路的故障模式及相关故障树分析

Analysis of the Fault Modes and Interrelated Fault Trees of Overhead Transmission Lines

架空输电线路是电力系统中的重要部分,由于自然环境、外力破坏、生产质量以及人为因素等造成了架空输电线路等的大量故障情况,给电网的安全稳定运行带来了巨大隐患。采用故障模式及影响分析方法,详尽分析了架空输电线路的结构组成与故障情况,得出了其故障模式分析表;在故障模式分析表的基础上建立了基于故障模式分析的架空输电线路故障树分析模型。

The overhead transmission line is an important part of the power system. A large amount of faults caused by natural envi- ronment, external forces, production quality and human factors in the overhead transmission lines bring great hidden trouble to the safe and stable operation of the power grid. In this paper, the Fault Mode and Effect Analysis is adopted to analyze the architecture and the fault condition of the overhead transmission lines, and obtain the table of the fault mode analysis ; Based on the fault mode analy- sis table, the fault tree analysis model of the overhead transmission lines is established on the basis of the fault mode analysis.
