摘　　要：合成场强特性研究对于换流站管母线的选型和布置具有重要意义。在Deutsch假设基础上,建立换流站管母线表面场强和地面合成场强的计算模型,提出了±800 kV换流站合成场强特性的控制指标,对不同型号换流站管母线的电晕特性和合成场强进行了计算,得到了管母线起晕的高度范围和不同高度下地面最大合成场强的计算值,通过对结果的分析,给出了换流站管母线安装高度要求和选型建议。Study of electric field characteristics of busbar in the HVDC substation is substaintial to the substation design.Based on the Deutsch assumption,a computation model is established in this paper for the busbar surface electric field and ground total electric field of converter substation and the controlling indices of the total electric field are proposed for the ±800 kV converter substation.With this model,the corona characteristics and the total electric field of various typies of busbars are calculated and the height range of busbar installation and the total electric field on the ground is obtained.As a conclusion,the busbar type and installation method in the ±800 kV converter substation is suggested.
