摘要
以浙西换流站为研究对象,建立了换流站及其交直流侧2 km内进线段模型,选取雷电参数,并采用EMTP仿真计算了换流站雷击模型,讨论了换流站交流侧运行方式的选择,最后给出了相应降低雷电过电压的改进措施。
Zhexi station and it's 2 km line in segment's mode were studied,the selection of lightning's amplitude was discussed.EMTP was used to analyze the equipment's lightning overvoltage.To analyze the most serious situation,the selection of AC field's operation mode was discussed in detail,finally measures to limit the lightning overvoltage were introduced.
