摘要
直流换流站主接线的选择是±800kV特高压直流工程设计前期的重要环节。介绍了直流工程换流站可行的主接线方案及其特点,从设备设计与制造的技术难度、设备运输、系统运行可靠性、对交流系统的影响、换流站的分期建设及投资造价这六方面对提出的单12脉动接线和双12脉动串联接线方案进行比较优选。经过研究分析得出结论:±800kV直流输电工程换流站较为适合的主接线为双12脉动串联接线。
Main electrical scheme of converter station is the key point at the foremost study on the ±800kV HVDC projects. The feasibility of main electrical schemes are brought. This paper compares single 12-pulse converter per pole scheme with double 12-pulse converter per pole scheme by taking account of technology difficulty, transportation, reliability, system operation, construction by stages, investment and so on. In the end, after the discussion a conclusion is drew that two 12-pulse converter per pole scheme is more suitable for ±800kV HVDC project.
