摘要
针对哈密—郑州±800kV特高压直流工程需和其他2条特高压直流线路同走廊问题,对三回同走廊特高压直流输电线路的地面合成场强、无线电干扰及可听噪声进行了分析,得出同走廊电磁环境控制时的走廊范围和房屋拆迁范围,可为设计和运行单位提供参考。
The UHVDC transmission line between Hami and Zhengzhou needs the same corridor with other two-circuit UHVDC transmission lines. In the three-circuit UHVDC transmission lines with the same corridor, total electric field strength in the ground, the radio interference and audible noise are analyzed. In addition, the width of transmission line corridor and demolition range are obtained under the electromagnetic environment requirements, providing references for the design and maintenance practice of overhead lines.
