摘　　要：输电线路风偏跳闸是影响贵州电网安全运行的主要故障之一,本文通过分析风偏跳闸机理、外部条件影响,筛选影响风偏跳闸的关键因子,构建风偏故障预警分析模型,并通过实际案例对风险评估模型有效性进行了分析验证。The windage yaw flashover trip was one of the main fault affecting the safety operation of Guizhou Power Grid. The paper analyzed the mechanism of windage yaw flashover trip and external condition effect, the key factor of windage yaw tlashover trip was screened out and the windage yaw flashover fault forewarning analysis model was structured. Finally, a practical case verified the validity of the risk evaluation model.
