摘　　要：基于电压源型换流器VSC(VoltageSourcedConverter)的多端新型直流输电系统VSC鄄MTDC(VSC鄄Multi鄄TerminalDirectCurrent)具有广阔的应用前景,如中/低压输配电、分布式发电、电力市场应用等。首先介绍了VSC鄄MTDC的基本原理与控制方法。随后提出了一种多点直流电压控制方法。通过原理分析与仿真实验,证明该方法是切实可行的,且比单点直流电压控制具有更多的优点,如改善直流电压的质量、提高换流器利用率等。A VSC(Voltage Sourced Converter) based multi-terminal HVDC(VSC-MTDC) can be an attractive scheme in power distribution,distributed generation and power market,etc. The elementary structure and the control scheme of VSC-MTDC(VSC-Multi-Terminal Direct Current) are described and a multi-terminal DC voltage control scheme is proposed. Performance analysis and simulation verify the feasibility and advantages,such as DC quality improvement,converter utilizability enhan-cement,etc.
