  • Obtained by emtp program and the egm , this paper studies on lightning protection performance on 500kv double circuit transmission line the distributed parameter model of tower is built when analyzing the back stroking lightning protection performance for double circuit line , it can truly reflect the spreading course of lightning current on the tower , furthermore , considering the randomness of working voltage ' s phase when lightning strokes the top tower and supposing the probability of lightning appearing arbitrary phase in a cycle of ac is equal , this paper brings forward the statistical method to calculate the rate of back stroking on double circuit line
    本文利用emtp程序、击距法对500kv同杆双回线路的耐雷性能进行了研究。在分析同杆双回线路的反击耐雷性能时,建立了杆塔的分布参数计算模型,此模型可以真实地反映雷电流在杆塔上的传播过程。并针对雷击塔顶时,导线运行电压相位角的随机性,本文假定雷击出现于交流一周期的任一角度区间内的概率相等,提出了利用统计法计算同杆双回线路的反击跳闸率。
