摘　　要：500kV狮洋—五邑输电线路部分线段计划利用已有的线路走廊进行改造,改造段拟按500kV同塔四回线路设计,设计关键问题是线路有关参数要符合电磁环境的要求。采用"ATP/EMTP"计算程序,对500kV同塔四回线路的电磁环境进行模拟计算,与国内外的相关标准进行比较。计算结果表明,该塔型设计合理,其电磁环境能满足国家的相关标准和要求。500 kV Shiyang-Wuyi transmission line has been planned to adopt existing line corridor for its partial retrofitting, and the retrofitted section will be designed based on 500 kV 1-tower 4-circuit line. Its key issues are that its concerned parameters should meet requirements for electromagnetic environments. A simulation of its electromagnetic environment was executed with ＂ATP/EMTP＂ software, whose results were compared to concerned both domestic and foreign standards. The resuits prove that the design of tower type is rational and can meet related national standards and requirements for electromagnetic environment.
