摘要
通过对广东佛山地区110~500kV典型架空输电线路和变电站周围的电磁环境参数(工频电场、工频磁场、无线电干扰)进行实际测量和仿真计算,分析了不同电压等级、不同类型典型架空线路和变电站周围的电磁环境水平及分布状况。统计结果表明,各电压等级、各类型输变电设备周围电磁环境参数均满足国内外相关标准限值要求。重点分析了500kV输电线路、220 kV城区变电站等输变电设备周围电磁环境参数测试结果和分布特点,针对可能出现的输变电设备电磁环境超标问题提出输变电工程规划的设计建议。
By field measurement and simulation of electromagnetic field of 110～500 kV typical transmission lines and substations in Foshan area,the electromagnetic environment impact and distribution levels around different transmission lines and substations are given.The results show that all environment parameters meet related standard requirement.The characteristics of electromagnetic field around transmission device such as 500 kV transmission line and 220 kV urban distribution station are analyzed in detail.Suggestions for planning and design of future transmission network with respect to electromagnetic field environment problem are proposed.
