摘　　要：为满足超远距离大容量电力输送需求,研究更高电压等级的直流输电技术是可行方案之一。文章重点对±1 500 kV电压等级直流输电系统主回路进行概念设计,提出适应±1 500 kV电压等级直流输电需求的3个12脉动换流器分层接入的主接线型式,并结合该接线型式特点提出了包括双极混合电压、双极2/3(1/3)电压等方式在内的多种直流运行方式;提出±1 500 kV特高压直流输电工程换流变压器、平波电抗器、直流滤波器和无功补偿设备等关键设备参数的可行方案。In order to meet the demand of interconnection of ultra-long distance and large capacity power transmission,one of the feasible schemes is to study direct current (DC) transmission technology with higher voltage level. This paper focuses on the conceptual main circuit design of the ± 1 500 kV voltage-class DC transmission,proposes a wiring pattern in which three 12-pulse converter are connected in series. Combined with the characteristics of the wiring type,various DC operation modes including bipolar hybrid voltage mode and bipolar 2/3 (1/3) voltage mode are proposed. It also forms a recommended scheme for key equipment parameters such as ± 1 500 kV DC engineering converter transformer,smoothing reactor,DC filter and reactive power compensation equipment.
