摘要在考虑桥臂电流包含所有次谐波成份的基础上, 提出一种新的模块化多电平变流器(MMC)稳态运行特性分析方法。通过研究分析MMC内部各电气变量间的耦合关系, 推导得出系统通用矩阵方程, 进而得到桥臂电流、子模块电容电压、相间环流等电气变量解析表达式, 并总结了各变量稳态运行规律。该方法计算过程相对简单, 计算结果更为精确。基于23电平MMC背靠背平台的仿真、实验结果与理论分析结果对比, 证明了所提方法的可行性与可靠性。

Abstract：Considering all the harmonic components for the arm current, this paper proposes a new steady-state operation characteristic analysis method for the modular multilevel converter(MMC).Based on the analysis of the coupling relationship among the internal electric variables of MMC, the general matrix equation of the system is derived and the analytical expression of the arm current, submodule capacitor voltage and circulating current is obtained, and then the operation law of these variables is concluded.The calculation process is relatively simpler and the analysis results are more accurate with this method.The simulation and experimental results based on 23-level MMC back-to-back platform are compared to the analytical results, respectively.It verifies that the proposed method is feasible and accurate.

Key words： Modular multilevel converter steady-state circulating current general matrix equation
