摘要

随着柔性直流技术的不断成熟，基于电压源换流器(voltage source converter, VSC)的交直流混合配电网成为未来城市配电网的发展趋势。文章对不同类型换流器进行了对比，结果表明VSC在控制灵活性方面具有更大优势；分析了VSC控制方式，并给出了基于VSC单极对称接线方式的直流线路最大传输容量；提出了一种交流系统和直流系统间解耦求解的潮流计算方法，可适用于含多端直流的复杂交直流混合配电网，并能够保证潮流计算的简易与快速性。通过对比商业化潮流求解软件DIgSILENT和本文所提方法，验证了本文所提方法的正确性。

Abstract

With the development of flexible DC technology, hybrid AC/DC distribution networks based on voltage source converter (VSC) has become the future trend of urban areas. This paper compares different types of converters, the results show that VSC has greater advantages in control flexibility. The VSC control method are analyzed, and the maximum transmission capacity of DC line based on the VSC unipolar symmetric wiring method is proposed. A power flow calculation method through decoupling between AC system and DC system is proposed, which can be applied to a complex AC/DC hybrid distribution network with multi-terminal DC, and can ensure the simplicity and rapidity of power flow calculation. Through the comparison between the commercial power flow solving software DIgSILENT and the proposed method, the correctness of the proposed method is verified.
