Abstract

The recent development of modular multilevel converters (MMC) provides new opportunities for medium voltage DC (MVDC) systems for all electric ship design and offshore wind parks. Therefore, the Center for Advanced Power Systems at Florida State University has recently commissioned a new MVDC power-hardware-in-the-loop laboratory rated at 5 MW at DC voltages between 6...24 kV. The new lab features four individual MMCs, each composed of 36 full-bridge cells, and capable of delivering 210 A at 0...6 kV. This paper describes the entire system in detail, including the advanced current and voltage control concepts along with the state of the art digital control hardware. Selected commissioning results demonstrate the performance of the system under dynamic conditions and provide comparison with simulations obtained from a corresponding controller hardware-in-the-loop setup which is also described in the paper.

基于模块化多电平变换器(MMC)技术的多功能兆瓦级中压直流试验台

模块化多电平变流器(MMC)的最新发展为所有电动船舶设计和海上风电场的中压直流(MVDC)系统提供了新的机会。因此，佛罗里达州立大学先进电力系统中心最近委托了一个新的MVDC电源硬件在环路实验室，额定直流电压在6…24 kV。新实验室有四个独立的mmc，每个mmc由36个全桥细胞组成，能够在0…6 kV。本文详细介绍了整个系统，包括先进的电流和电压控制概念以及最先进的数字控制硬件。所选的调试结果显示了系统在动态条件下的性能，并与相应的控制器半在环设置的仿真结果进行了比较。
