摘要

对一种新型的模块化多电平变流器（MMC）在轻型直流输电系统（VSC-HVDC）中的应用进行了研究。首先建立了MMC系统的数学模型，提出了适用于MMC系统的快速脉宽调制控制方法、模块电容电压平衡控制策略以及降低器件开关频率的方法。对于系统级控制，提出了基于MMC的VSC-HVDC输电系统非线性控制器，包括有功功率和无功功率解耦控制器，以及直流侧电压控制器。通过PSCAD/EMTDC仿真软件对所提出的模型和控制方法进行了验证，证实了其可行性和有效性。

Abstract

This paper researches the application of a novel MMC in the VSC-HVDC system. First， the mathematic model of MMC system is established. Then fast PWM control for MMC system， the balance control for the DC voltages of modules， and methods to reduce switching frequency are proposed. As the system-level control， the nonlinear controller for VSC-HVDC system based on MMCs is designed. It includes decoupling control of active power and reactive power， and the constant DC voltage control. By simulation with software PSCAD/EMTDC， the feasibility and effectiveness of the proposed model and control are verified.
