| Abstract: | At present,it is required that the polarity distance of ±800 kV UHV DC transmission lines constructed or constructing is not less than 22 m in our country.In this paper,the possibility of decreasing the polarity distance is discussed by considering electromagnetic environment,length of the composite insulator string,air gap,angle of the V style insulator string and so on.In addition,the economic benefits are analyzed.The results obtained provide references for the design of future UHVDC transmission line. |
