摘　　要：利用Bergeron特征线法,编程对同杆双回交流500 kV输电线路的反击耐雷性能进行了详细的计算和分析,考了雷击塔顶时导线上交流工频电压的随机性,利用统计法确定超高压线路的反击耐雷性能。并分析了接地电阻对同杆双回线路耐雷水平的影响。This paper details the lightning protection performance of back striking for Ac 500kV double-circuit transmission line by program in the case of Bergeron traveling wave method. Astatistical method is brollght forward with considering the randomness of working vohage＇s phase in the case of lighting striking the top tower, the effects of grouding risistance for the shared tower double-circuit 500kv transmission lines are discussed in details.
