针对远海风电柔直送出工程，模块化多电平换流器MMC（modular multilevel converter）的质量和体积大、海上换流站的建造成本高的问题亟待解决，因此MMC的轻型化研究是目前的研究热点之一。首先提出1种优化配置型MMC（optimized configuration MMC），给出其配置方法，并在最近电平逼近调制的基础上设计均压策略。新型换流器通过引入2种电容容值相同，额定电压相差K倍的子模块，提高了交流侧输出电压的电平数。通过MATLAB/Simulink仿真结果和物理实验验证发现，换流器能够顺利完成电压变换工作，系统的稳态运行特性与常规MMC相近，且动态特性良好。在2种换流器交流电压电平数相同的前提下，相较于常规MMC，所提OC-MMC能够间接减少子模块装配数量，降低换流站的质量、体积和投资成本，从而实现轻型化目标。

Aimed at an offshore wind power flexible DC transmission project, the problems of the large mass and volume of modular multilevel converters (MMCs) and the high construction cost of offshore converter stations need to be solved urgently. Therefore, the lightweight research of MMC is one of the research hotspots at present. First, an optimized configuration MMC (OC-MMC) is proposed, and its configuration method is given. In addition, a voltage balancing strategy is designed based on the nearest level modulation. The novel converter improves the number of output voltage levels on the AC side by introducing two submodules whose capacitance values are the same but the rated voltage values are proportional by a factor of K. Then, through the simulation results on a MATLAB/Simulink platform and experimental results, it is found that the novel converter can successfully complete the voltage conversion process. The steady-state operation characteristics of the system are similar to those of a conventional MMC, and the dynamic characteristics are good. On the premise that the numbers of AC voltage levels of the two converters are the same, the proposed OC-MMC can indirectly reduce the number of submodule assembly and reduce the mass, volume and construction cost of the converter stations compared with the conventional MMC, so as to achieve the goal of lightweight.
