摘要(Abstract)：

根据极导线垂直和水平排列高压直流输电线路几何结构的特点,在考虑正、负极导线起晕场强不同和正、负离子不同迁移率的基础上,比较分析了极导线垂直和水平排列±500kV直流输电线路的电磁环境特点。结果表明:相对于极间距和极导线对地最小高度分别相同的水平排列线路,负极导线在下的垂直排列线路的地面合成电场强度、空间电荷密度和离子流密度的最大值较大,无线电干扰电平和可听噪声水平较低;而正极导线在下的垂直排列线路的地面合成电场强度、空间电荷密度和离子流密度的最大值较小,但其无线电干扰电平和可听噪声水平较高。

关键词(KeyWords)： 高压直流输电线路;极导线垂直和水平排列;合成电场强度;无线电干扰;可听噪声
