输电线路长期暴露于大气环境当中，易受雷电、台风、暴雨等灾害性天气影响而发生故障，故障原因不同电网的应对措施应有不同。研究了不同天气状况下输电线路故障的概率，提出了依据统计分析结论，在预报的气象状况下，对存在故障风险的线路集，对 N-m 故障风险进行评估，并以此为依据选择电网运行方式以降低系统风险、提高系统抵御恶劣自然灾害的能力。通过对南方沿海某地区的灾害性天气的分布特征进行统计分析，得到了灾害性天气在不同时间范围爆发的频度，使用RBTS系统进行测试，验证了该方法的可行性。

Transmission lines are long exposed to nature environment and are vulnerable to adverse weather conditions such as lightning, typhoon, rainstorm and so on. Different measures should be taken according to different fault causes. This paper studies the fault probability of transmission line under different weather conditions, and proposes to assess theN-m risk under forecasting weather condition for those high fault risk lines based on the analysis results, then chooses the operation mode to reduce the system risk and enhance the ability of defense the adverse nature disasters. Through statistical analysis of the distribution characteristics of adverse weather in a southern China area along the coast, getting the frequency and degree of adverse weather in different time, and through testing on RBTS, the feasibility of the proposed method is verified.
