摘要

在传统模拟电荷法的基础上

建立了高压输电线路地面电场强度的计算方法

其中在计算中考虑了计及电晕放电的影响。以750 kV水平排列和紧凑型线路为例

计算了导线表面系数、线路的子导线半径、相间距、导线对地高度、分裂导线数目、分裂间距等对工频电场的影响。仿真结果表明

减小电晕放电对地面电场影响的几种方式中以适当增加导线的表面系数和对地高度效果最为有效。

Abstract

Based on the traditional charge simulation method

the computation method of electric field intensity of the high-voltage transmission lines taking account the corona discharge was built.In the paper

it is applied in the computation the 750 kV AC transmission lines’ground level electric field

which is in compact arrangement and in the parallel arrangement.The effect factors are including the conductor coefficient

the sub-conductor radius

the phase spacing

the conductor height

the split-conductor number

and the split-conductor spacing.The simulation results showed that increasing the conductor coefficient and the conductor height can reduce the effect of the corona discharge on electric-field intensity.
