摘要

采用上流有限元法定量分析了离子迁移率和离子复合率对±800 k V特高压直流输电线路地面合成场强和离子流密度的影响。结果表明

离子迁移率对地面合成场强影响不大

而地面离子流密度随着迁移率的增大呈线性变化;两者均随离子复合率的增大而减小

且复合率对地面离子流密度计算的影响大于对地面合成场强的影响。

Abstract

Based on the upstream finite element method

the effect of ion mobility and ion recombination rate on the ion current density and total electric field at ground level of ±800 k V transmission lines are analyzed quantitatively. Results show that ion mobility has little effect on total electric field at ground level

while ion current density changes linearly with the increase of ion mobility. The two parameters decrease with the increase of ion recombination rate and the influence on ion current density is much greater than the total electric field at ground level.
