摘　　要：特高压交流架空输电线路的防雷对系统的安全运行极为重要。本文运用PSCAD／EMTDC建立特高压输电线路、杆塔、绝缘子串的伏秒特性等计算模型，对特高压交流输电线路三种形式的雷击过电压仿真计算，从而分析绕击、雷击塔顶、雷击档距中央避雷线的耐雷水平，为我国同类特高压输电线路的防雷保护提供数据参考。Lightning protection of UHV AC transmission line is very important to the system＇ s safe operation. Based on PSCAD/EMTDC, build calculation models, such as UHV transmission lines, tower, volt - second characteristics of insulator string. Calculate the three forms of lightning overvoltage simula- tion of UHV AC transmission line, then analyze detour lightning, lightning tower, lightning resisting level of the lightning file from the central lightning conductor, which provides reference data for lightning pro- tection Of similar UHV transmission line.
