为研究实际运行特高压直流输电线路复杂环境的合成电场特性及环境影响,开展±800 kV云广直流线路合成电场测量与分析.建立了特高压直流输电线路合成电场计算模型及算法流程,阐述了特高压直流输电线路合成电场的测量仪器、环境、位置、数据记录和处理方法.不同运行方式下的测试结果表明:正极半压和负极全压下测量值与理论值的误差小于负极全压运行下的误差,但大于双极全压运行下测量值与理论值的误差;因测试点的海拔高度、导线对地高度、温/湿度、风速、风向等因素影响,负极半压、正极半压和负极全压、负极全压运行的合成电场值上下浮动于不同月份的双极全压测量值;不同测试点的合成电场的80%值和95%值对应的测量位置基本相同,同时所有测量结果满足合成电场环境限值且有足够的裕度.云广直流工程的电磁环境设计合理性得到了验证.
