摘　　要：利用编制的电磁环境计算软件,对750 kV同塔双回交流架空输电线路电磁环境进行了仿真研究,分析了导线对地高度、相序布置、分裂数、子导线直径、分裂间距等因素对电磁环境的影响,依据相关的限值要求提出了控制措施。Using simulation software of electromagnetic environment which had been explored, this paper makes detailed research on electromagnetic environment of 750 kV double circuit transmission lines on the same tower. The influence regularities with different conductor height,diameter of sub-conductor, multiple conductor numbers, splitting spacing and different arrangement of conductors are analyzed. According to the request of control index, some control methods are proposed.
