高压交直流输电线路平行架设时的电场线轨迹

Electric Field Line Trajectory for Parallel AC /DC Transmission Lines

提出了一种电场线轨迹数值求解的一般方法,此方法可以有效地描述高压输电线路情况电场线的完整轨迹。采用该方法得到了极导线水平排列和垂直排列高压直流线路的电场线分布。分析了交流输电线路电压和交直流输电线路间距的变化对直流线路电场线轨迹影响,结果表明,交流线路工作电压越高,对直流线路电场线轨迹影响越大;交直流线路间距越小,对直流线路电场线轨迹影响越大。

This paper puts forward a general numerical solution for electric field line trajectory,which can effectively describe the complete electric field line trajectory of HV transmission line,and derive the electric field line distribution of HV DC lines with the horizontally and vertically arranged wires. The impact of AC transmission line voltage and AC /DC transmission line spacing changes on electric field line trajectory of DC line is analyzed. The results show that the higher the AC line working voltage,the greater the impact on the DC line electric field line trajectory; the smaller the AC /DC transmission line spacing is,the greater the impact on the DC line electric field line trajectory.
