摘　　要：对当前普遍适用的4种雷击跳闸率计算方法,通过典型实例进行仿真计算,认为以ATP/EMTP法及修正后电气几何模型计算获得的杆塔雷击跳闸率更符合线路实际运行情况,建议将其作为330 kV线路雷击跳闸的计算方法。同时以330 kV玛玉线为典型实例进行防雷评估,获得各雷害风险等级杆塔分布情况量化结果,也可以为线路防雷改造提供直接指导。By the simulating calculation of typical examples of 4 common calculation methods of lightning trip-out rate,This paper concludes that the data of lightning stroke trip rate calculated via ATP/EMTP method and modified electrical geometry model method are more consistent with the actual operation of the line,and it is suggest to use those two methods as the calculation method for lightning trip-out rate of 330 kV transmission line. Meanwhile,taking an anti-lightning evaluation and assessment for 330 kV Mahe-Yushu line as a typical example,the quantification result of tower distribution of various level of thunder and lightning risk is proposed to provide direct guidance for the lightning protection transformation of the line.
