Abstract The Modular Multilevel Converter (MMC) is a power electronic structure used for high voltage adjustable speed drives applications as well as power transmission applications and high-voltage direct current. MMC structure presents many advantages such as modularity, the absence of a high voltage DC bus and very low switching frequency. It presents also some disadvantages such as modeling complexity and control due to the large number of semiconductors to control. The objectives of this paper are to present the methodology to design a laboratory MMC converter and its control system. This methodology is based on an intensive used of real-time simulation, to develop and test the control algorithm is proposed. This MMC prototype must be as realistic as possible to a full scale MMC, with a large number of sub-modules (i.e. 640 kV on the DC side, a rated power of 1 GW and 400 sub-modules). A control hardware integrating distributed processors (one for each arm) and a master control is presented. The protocols to validate sub-modules, arms and the converter are explained.

模块化多电平转换器的设计、实现和测试

摘要 模块化多电平转换器(MMC)是一种电力电子结构,用于高压调速驱动应用以及电力传输应用和高压直流。MMC 结构具有许多优点,例如模块化、没有高压直流总线和非常低的开关频率。由于需要控制大量半导体,因此它还存在一些缺点,例如建模复杂性和控制。本文的目的是介绍设计实验室 MMC 转换器及其控制系统的方法。这种方法是基于实时仿真的密集使用,提出了开发和测试控制算法。该 MMC 原型必须尽可能逼真,具有大量子模块(即直流侧 640 kV,1 GW 的额定功率和 400 个子模块)。介绍了一种集成分布式处理器(每个臂一个)和主控制的控制硬件。解释了验证子模块、臂和转换器的协议。
