摘　　要：随着柔性直流输电技术逐步走向成熟,多端柔性直流(VSC-MTDC)输电系统多电源供电、多落点受电的特点,使其作为一种更为灵活、快捷的输电方式得到了极大发展。本文首先通过VSC-MTDC输电的拓扑结构和基本控制原则对其进行了概述。然后从国内外现有的VSC-MTDC输电系统工程实例和研究现状两个方面来分析了VSC-MTDC的发展现状。最后对VSC-MTDC输电技术在分布式新能源并网、弱系统或孤岛系统供电、大电网的非同步联网以及大城市的电网增容与直流供电等领域的应用前景进行了展望。With flexible HVDC technology gradually matured,VSC-MTDC transmission system has the features of multiple power supplies and multidrop powered.This makes it as a way of more flexible and efficient transmission got great development.Firstly,this paper make the overview of VSC-MTDC transmission through its topological structure and basic control principle.Then two aspects about the VSC-MTDC transmission system engineering examples and the research status quo at home and abroad are introduced to analyze the VSC-MTDC development present situation.Finally,the application prospects of VSC-MTDC transmission system,such as renewable power integration,power supply of weak power system and island,nonsynchronous connecting of bulk grid,DC power supply and distribution of large city and other areas,are provided.
