摘　　要：柔性直流输电系统的拓扑结构是其关键技术之一,对整个工程的性能和成本影响巨大。首先介绍了国内外柔性直流输电工程的发展情况,并分析了各种电压源换流器、模块化多电平换流器的技术原理。然后着重阐述了柔性直流输电系统主接线拓扑结构的最新研究情况,并对其应用范围、优缺点等做了归纳和分析。在此基础上提出将柔性直流输电仿真技术等作为下一步研究工作的重点,为今后的柔性直流输电工程拓扑方案的研究提供了一定的理论借鉴。Topological structure is one of the key techniques of flexible HVDC, which has great influence on the performance and cost of a project. The development status of flexible HVDC projects at home and abroad are introduced and the technological principle of VSC and MMC are analyzed. Then the current research on main electrical connection topological structure of flexible HVDC system are introduced, and their application range, advantages and disadvantages, etc. are concluded and analyzed. On the basis, the suggestion about taking flexible HVDC simulation technology as the interesting direction of next research is presented. This paper provides a theoretical reference for the topological structure research of flexible HVDC system in future.
