摘要
基于对下行雷闪物理过程的认识和对输电线路绕击分散性的研究，建立了考虑放电分散性的输电线路雷屏蔽性能的雷击仿真模型。仿真计算结果表明，该模型与现场运行经验相符，并成功地解释了EGM难以解释的现场事故。
Based on the knowledge of physical process of downward lightning stroke and the study of shielding failure dispersal of transmission line, a lightning stroke simulation model on lightning shielding performance of transmission line is presented,in which the discharge dispersal is taken into account. The simulation calculating results show,the model is in agreement with field experience and can give a gnd explanation of a field accident which is difficult to explain by EGM.
