输电线路耐雷性能计算方法的研究现状分析

从实际运行来看，雷击仍然是危及输电线路安全可靠运行的主要原因。文中较为详细地介绍目前用于分析输电线路反击耐雷性能的规程法、行波法、蒙特卡洛法、故障树法、EMTP程序等各种计算方法的原理及特点和用于分析输电线路绕击耐雷性能的规程法、击距法、先导发展模型等各种计算方法的原理及特点，同时对于输电线路绝缘闪络的判据也作了简单介绍，并就今后的研究重点提出了自己的看法。

Analyze the Present Status in the Calculation Methods of Lightning Protection Performance for Transmission Line

Lightning is the main reason that endangers transmission line working safety and reliabilty today. The theory and characteristic of methods that not only estimate the lightning performance for back strike such as standard method, traveling wave method, Monte Carlo technique, treeing fault method, EMTP and so on but also for the shielding failure such as standard method, EGM, leader progression model and so on are summarized. The criterion of flashover for insulators is referred simply, furthermore, it gives the opinion that the development of research for the future.
