摘要
高压输变电工程进入城市中心地带是发展的趋势,而工频电磁环境是居民关注的问题,根据目前广州城市电网建设的现状,对广州城区110 kV、220 kV各类型变电站、多种形式的输电线路产生的工频电磁环境影响进行分析,对比国家现行标准限值,评价广州城市电网工频电磁环境影响的总体情况,认识电网的未来发展趋势,并结合输变电电磁环境影响特点提出相应广州电网建设的意见与建议。
It is a trend that power transmission and transformation projects have entered the center of city. And the residents have paid more attention to the power frequency electromagnetic environment. According to the present situation of electric network construction of Guangzhou, the electromagnetic environmental impact of each kind of 220 kV and 110 kV substations in the urban power grid of Guangzhou are analyzed. Besides, the environmental impact of various forms of overhead lines and cable are also analyzed in this paper. Compared with the limit value in the presentational standards, the overall condition of the electromag- netic environmental impact of Guangzhou and the coming trend are understood. The corresponding suggestions of development of city electric network are proposed combined the electromagnetic environmental impact characteristics of power transmission and transformation projects.
