±800kV/±500kV混压双回直流线路的电磁环境分析及改善研究

Gaoya dianqi, 2016
±800 kV/±500 kV混压双回直流输电线路可解决中国日益增长的电力需求和输电走廊资源紧缺的矛盾,但目前尚无建造和运行经验,研究其电磁环境具有重要工程指导意义。文中采用解析法、CISPR和BPA经验公式法等方法,计算了两种基本塔型及相应导线布置方式下的导线和地线表面场强、地面电场和离子流密度分布、线路最小对地距离和走廊宽度、可听噪声和无线电干扰等电磁环境相关指标,分析了不同因素（导线排列方式、导线高度、线间距离等）对电磁环境的影响,并与±800 kV直流单回线路和±500 ...

±500 kV同塔双回直流输电线路电磁环境测试分析

Gaoya dianqi, 2018
为了研究±500 k V同塔双回直流输电线路运行期间各项电磁环境参数对环境影响情况,对溪洛渡直流工程运行期间不同运行工况下的不同架设方式的直流输电线路开展了电磁环境测量。分析结果显示:同塔双回直流在均带电运行的情况下较单回线路带电运行的电磁环境影响更小,不同架线运行方式的合成场强、离子流密度、可听噪声和无线电干扰电磁环境参数测试值均能满足相关国家标准和行业标准的规定。并验证了在直流线路工程前期对电磁环境因子计算研究能有效反应运行期间的电磁环境水平,有效避免了运行后由电磁环境带来的纠纷问题。
