摘　　要：为研究真实环境下高压输电线路的工频电场,基于有限差分思想,提出对地形阶梯近似的剖分方法,并对有限差分法进行改进,实现了真实地形中高压输电线路三维空间电场分布的仿真,同时进行了验证.这种考虑真实地形的计算模型大大提高了工频电场计算的准确性,可为高压输电线路在复杂地形架设时,线路设计和电磁环境分析提供参考.To study the power frequency electric field：under the real environment precisely, based on the finite difference method, this paper utilizes a method that is approximate to terrain ladder triangulation and improves the finite difference method, thus realizing the 3D simulation of the distribution of the power frequency electric field under the condition of real terrains. The calculation model considering the real ter- rains greatly improves the accuracy of the power frequency electric field. The results from the proposed modeling can provide reference for transmission line design and electromagnetic environment analysis when erecting high voltage transmission line in complex terrains.
