摘要(Abstract):
采用PSCAD/EMTDC程序计算分析了江苏抽水蓄能电站500kV变电站雷电侵入波保护的效果,考虑了不同运行方式、不同雷击点的情况,还计算分析了杆塔冲击接地电阻、避雷器的布置及参数对保护效果的影响。计算结果表明,该工程的雷电侵入波保护避雷器的配置和接线方式可以满足安全可靠性的要求。
The scheme of lightning protection against intruding wave in Jiangsu pumped-storage power station is analyzed by numerical simulation with PSCAD/EMTDC in this paper. Some factors, including different operation mode and lightning strike location, are considered, and the effect of impulse grounding resistance of tower and layout of lightning arrestors on protection purpose is also analyzed. The calculated results indicate the scheme of lightning protection in this project is reasonable.
