| 摘 要： | 提出了一种对架空输电线路的运行状态进行评估的分析法,该分析法使用可靠性评估中的FTA法,即故障树分析法创建数学模型。该模型运用故障树分析中的下行法计算架空输电线路的最小割集,并用最小割集理论建立故障树。同时根据现场专家给定的权值和故障树的计算原理给出了相应线路运行状态可靠性评估的计算公式;结合现场取回数据的具体算例进行分析并计算了架空输电线路的不同运行状态可靠性指标,取得了良好的计算结果。

| Abstract: | This text put forward a kind of analytical method to evaluate the power line that builds on stilts.This analytical method uses the way named FTA(Fault Tree Analysis) in reliability evaluation to build math model.This model uses the theory of the Fussell-Vesely in reliability evaluation to work out the minimum cut sets,and using the minimum cut sets to make the fault tree.Furthermore,based on the coefficient which was given by experts in work field and the calculation theory of FTA,the calculation formula of evaluation on the reliability of the power line was given accordingly.Combined with practice,it analyzes and calculates the reliability on different circulated states of the power line and obtains good result. |
