摘要
±800 kV特高压直流换流站的绝缘配合设计是特高压直流工程实施中的关键技术之一,对换流站设备设计、选型、制造和试验具有重要的指导作用。基于特高压换流站绝缘配合方法,对溪洛渡—浙西±800 kV特高压直流输电工程逆变侧浙西换流站的绝缘配合进行研究,提出了浙西换流站避雷器配置方案和相应避雷器参数及保护水平,并根据推荐的绝缘裕度最终确定了换流站设备的绝缘水平,这些结果将为该特高压工程的建设提供重要依据,也可以为其他特高压直流工程的设计提供参考。
The insulation coordination of converter statiion for ±800 kV DC power transmission project is one of key techniques for the implementation of the project, and the insulation coordination will guide the design, type selection, manufacturing and testing of converter station equipments. Based on the insulation coordination method for UHVDC converter station, the insulation coordination of Zhexi converter station located at the inversion side of ±800 kV DC power transmission project from Xiluodu to Zhexi is researched, and the layout scheme of arresters installed in Zhexi converter station and corresponding arrester parameters and protection level are proposed, then based on the recommended insulation margin the insulation levels of converter station equipments are finally determined. The research results are available for reference to the construction of ±800 kV DC power transmission project from Xiluodu to Zhexi as well as the designs of other UHVDC power transmission projects.
