摘要
以500 kV高压同塔双回线路为研究背景,用PSCAD软件建立高压输电铁塔、铁塔分段输电线路、冲击接地电阻以及雷电浪涌模型,搭建仿真电路,分析了在档距,接地电阻,线路离地高度等不同的情况下应对雷击时的参数水平.为500 kV同塔双回线路防雷保护的设计以及工程搭建提供科学参考。
Based on the background of 500 kV same tower double-circuit transmission line, build models include high voltage transmission tower, segmented transmission line, impulse earthed resistance and lightning surge in PSCAD. Set up the simulation circuit, analyzed the parameters of transmission line while being struck by lightning in different situations, provided references for the design on lightning protection and engineering of 500 kV same tower double-circuit transmission line.
