摘要
张北柔性直流电网工程具有网络特性,其金属回流线绝缘配合的确定方法与以往直流输电线路工程有较大不同.本文根据该工程的特性,详细分析了在正常工作电压、操作过电压、雷电过电压下的金属回流线绝缘配置要求,给出了绝缘子片数配置建议.
Zhangbei VSC-HVDC power grid project has network characteristics,and the determination method of insulation coordination of metal refl ux line is quite different from the previous DC transmission line project.According to the characteristics of the project,this paper analyzes the insulation confi guration requirements of metal refl ux line under normal working voltage,operating overvoltage and lightning overvoltage,and gives suggestions on the number of insulator pieces.
