Recent developments in modular multilevel converters (MMCs) provide new opportunities for medium-voltage dc (MVDC) systems for all-electric ship design and offshore wind farms. 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 from 6 to 24 kV. The new lab features four individual MMCs, each composed of 36 full-bridge cells, capable of delivering 210 A at any voltage in the range of 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 are shown, which demonstrate the performance of the system under dynamic conditions and provide comparison with simulations obtained from a corresponding controller hardware-in-the-loop setup. The results indicate that an MMC-based MVDC system is a strong candidate for the ship power system because of its excellent fault management capability. The setup can be used for the understanding and design of fast fault management schemes in a breakerless MVDC system in the future all-electric ship.
