摘要 结合我国的特高压直流输电线路运行经验,对±660 kV直流输电示范工程建成投运后山西段内的运行特性及其对自然环境的影响进行了分析,重点阐述了±660 kV直流输电线路的防雷、防污闪、防冰、防舞动、防鸟害、防外力等特性,并提出了事故预想及降低故障跳闸率的对策。 Based on the experience from the operation of UHVDC transmission lines in China,the operation features of ±660 kV HVDC transmission demonatration project are analyzed in this paper.The impacts of ±660 kV HVDC transmission line on natural environment are also studied.The priorities are put on the analysis of the features,such as lightening protection,anti-pollution flashover,anti-icing,anti-galloping,bird harms prevention,and accident-preventing etc.The contingency anticipation and countermeasures to reduce the fault trip-out rate are proposed to guide the operation and maintenance of transmission lines.
