| 摘 要： | 为合理设计直流接地极系统,用数值分析法计算了高压直流输电直线型接地极系统各电气性能参数,讨论了不同模型、电流注入方式等对接地系统电气参数的影响。仿真表明,直线型接地极极体溢流密度、电位沿极体轴向分布明显不均匀;适当增加接地极导体半径和合适的电流注入位置均能优化设计,改善接地系统性能。

| Abstract: | Study on the ground electrode system is a significant topic related to the stability and economy of the HVDC system.Operation performance of HVDC linear ground electrode system is presented and discussed.By adjusting the key parameters,the distance of electrode conductors,the buried depth and so on,the conclusions are drawn that the distribution of dissipation current density and potential considerably changes along the electrode conductors,and it may be helpful for the optimization of linear electrode system to enlarge the radius of conductors or inject the DC current into the middle parts of the electrode conductors appropriately. |
