摘要 构建西电东送±1100 kV特高压直流输电大通道,有利于推进我国能源的大范围优化配置。在特高压直流输电系统中,换流器主接线方案对于整个直流主设备研制和工程实施的难度、可靠性水平、换流器故障所造成的交流系统功率损失等都具有重大影响,是工程系统研究的最核心问题。首先分析了特高压直流工程可采取的换流器接线型式;其次,根据以往工程建设经验和设备设计与制造经验,提出了3种换流器接线型式,并对其主回路技术参数进行了详细的计算分析;最后,根据所提的换流器接线型式评价方法,确定了合理有效的主接线型式,并在昌吉—古泉±1100kV工程中进行应用。

Abstract: Construction of ±1100kV UHVDC transmission channels from West to East in China is conducive to promote large scale optimal allocation of energy sources. In UHVDC transmission systems, main DC equipment development, project implementation, reliability level and power loss caused by converter outage are deeply impacted by main connection line of converter and main circuit parameters. This is also the most important step of project system research. Firstly, evaluation method of converter connection line of UHVDC projects are proposed in this paper. Secondly, according to previous project construction, equipment design and manufacturing experiences, three converter connection schemes are proposed and main circuit parameters are analyzed respectively based on each connection scheme. Finally, a proposed assessment method of converter main connection line is used to determine a reasonable and effective main connection topology for Changji-Guquan ±1100kV UHVDC project.
Key words:  ±1100kV UHVDC;    main connection line    main circuit parameters    series type converter    insulation coordination    reliability
