摘　　要：随着特高压交直流输变电工程建设的逐渐开展,该电压等级下线路走廊附近电磁环境越来越受到人们和环境部门的重视。以晋东南—南阳—荆门1 000 kV单回交流输电线路为例,利用ANSYS有限元分析软件对不同导线布置情况下输电线路附近的电场和磁场分布进行了建模分析。研究表明,1 000 kV特高压单回交流输电线路附近电磁场满足相关标准要求。With the gradual construction of the uhra - high voltage （UHV） AC/DC power transmission and transformation pro- jects, the electromagnetic environment near the line corridors under such voltage level gets more and more attention of the peo- ple and the environmental department. Taking Jindongnan - Nanyang - Jingmen 1 000 kV single - circuit AC transmission line for example, the distribution of electric field and magnetic field near the transmission line under different conductor configura- tions are analyzed in modeling using ANSYS finite element analysis software. The researches show that the electromagnetic field near 1 000 kV UHV single - circuit AC transmission line satisfies the requirements of the related standards.
