摘要
在接地极线路设计中,其绝缘配合水平选择的合理性关系到整个直流输电系统的安全可靠运行。以楚雄换流站接地极线路为例,简述了按照两端换流站及直流输电线路本体故障后在接地极线路上引起的操作过电压提高接地极线路绝缘配置的方法。
In the design of electrode lines,the selection of insulation coordination level relates to the safe and reliable operation of DC transmission system.Taking the electrode line of Chuxiong converter station for example,the method for enhancing the insulation level of electrode lines according to the condition of switching overvoltage caused by ontology fault of converter stations and DC transmission line is briefly described.
