| 摘 要： | 多年来柔性直流输电技术在我国一直处于理论研究阶段,近几年才开始兴建示范工程,主要采用伪双极接线方式,对于真双极接线以及混合接线方式研究较少。为对我国柔性直流技术的普及和工程应用提供参考,在PSCAD/EM TDC中搭建了两端伪双极、两端真双极以及两端混合接线的柔性直流系统详细模型,并对三种模型分别配置了避雷器保护初步方案,计算了这三种主接线模型在典型故障下换流站关键设备上产生的内部过电压以及避雷器上通过的电流和能量,计算结果可为今后柔性直流工程主接线设计、换流站绝缘配合研究以及相关设备的选型、试验等提供重要依据。

| Abstract: | In China, the MMC-HVDC transmission technology has been in the theoretical stage for a long time, demonstration projects are constructed or in construction only in the recent years, the pseudo bipolar wiring mode is mainly adopted in these projects, and there are rare studies on the bipolar mode and the mixed bipolar wiring mode. In order to provide reference for promoting and applying the MMC-HVDC technology in China, three kinds of detailed simulation model are established in PSCAD/EMTDC, preliminary lightning arrester protection schemes are proposed for each model, the inner transient overvoltage on key equipments of converter station, the current and energy of arresters are calculated at typical faults. The results help to provide important basis for main wiring mode design of MMC-HVDC projects, insulation coordination study of converter stations and selection and test of related equipments. |
