摘要(Abstract)：

±800 k V与±500 k V同塔双回直流输电线路可有效提高输电走廊的利用效率,但目前尚无设计和建设经验。针对电磁环境这一重要技术问题,基于Deutsch假设、经验公式分别计算了±800 k V与±500 k V同塔双回直流输电线路不同塔型和极导线布置方式下的地面合成场强和离子流密度、无线电干扰和可听噪声。结果表明:±500 k V线路布置于杆塔下层要求的最小对地高度较小;极导线同极异侧布置要求的走廊宽度较小,但可听噪声相对较高。计算分析了导线型号、线间距离和导线对地高度对电磁环境参数的影响,结果可为±800 k V与±500 k V同塔双回直流输电线路的工程设计提供参考。
