摘要

模块化多电平换流器（MMC）是一种适用于轻型直流输电系统（VSC-HVDC）的新型换流器

笔者在分析其原理的基础上研究了MMC的运行特性

并搭建了数学模型。文中所提出的MMC控制方法采用了移相载波调制策略（CPS-SPWM）的思想

针对MMC的电容电压均衡问题

通过算法重新分配子模块触发脉冲序列

最后仿真验证了该方法的正确性和可行性。

Abstract

Modular multilevel converter（MMC） is a new type of multilevel converter suitable for VSC-HVDC.Based on the analysis of its principle

MMC’s operating characteristics is studied in this paper

and a mathematical model is set up.Subsequently

a control strategy for MMC is proposed by making use of the strategy of carried phase shifted sinusoidal pulse width modulation（CPS-SPWM）.In order to solve the capacitancevoltage equilibrium problem

the trigger pulse sequence of each sub-module is redistributed through the algorithm.Simulation demonstrates the correctness and effectiveness of the proposed strategy.
