为研究特高压交流输电线路地面电场的分布特性以及电晕放电对地面电场的影响，通过改进基于模拟电荷法计算工频电场的方法，建立一种考虑电晕效应的导线电场计算模型，并通过算例分析验证了该模型的合理性。利用此模型对1000 kV特高压交流输电线路电晕影响下的地面电场进行数值仿真计算。结果表明：电晕放电对地面合成电场有加强作用，且中相线路正下方的地面电场受电晕放电的影响最大。
To study the distribution of ground electric field for UHV AC transmission lines and the effect of corona discharge on the ground electric field, we built an electric field strength calculation model of line considering corona effect by improving the calculation method of power frequency electric filed based on charge simulation method. The model was proved to be reasonable through example analysis. The ground electric field of 1 000 kV UHV transmission line under the effect of corona discharge was calculated by the model. The results show that the corona discharge can enhance the ground electric field, and the effect of corona discharge on the ground electric field under the middle phase of transmis-sion line is the biggest.
