摘要
随着国家“一带一路”建设的实施,未来电网将向跨国、跨洲联网方向发展,超远距离和超大容量输电亟需更高电压等级的直流输电技术。选定±1500 kV直流输电电压等级,按照典型的±1500 kV特高压直流输电线路工程设计条件,基于电磁环境、绝缘子串长和V串夹角、空气间隙的边界条件,对直线塔极间距进行研究,得到直线塔的最小极间距,为后续特高压直流输电线路的设计提供参考。
With the implementation of The Belt and Road Initiative,transnational and intercontinentalinterconnection will be a direction of power grid in the future.Ultra-distant and ultra-large capacity power transmission calls for DC transmission technology with a higher voltage level.Given the voltage level of a±1500 kV DC transmission line project,the polarity distances of tangent towers were investigated in conformity with the design condition,electromagnetic environment,insulator string length,angle of V-shaped insulator strings and boundary condition of air gap to conclude the minimum polarity distances of tangent towers to provide a reference for the design of UHVDC transmission line in the future.
