A nuclear submarine has significant performance advantages over the conventional diesel-electric submarine. Its powerful nuclear propulsion can be operated independently of air and does not require refueling throughout the 25-year life span. Recent progresses of medium voltage direct current (MVDC) techniques applied in industry push the energy-saving and extremely long-time operation to a new stage with a feasible solution of smaller scale nuclear reactor embedded inside the vessel. Thus, there is a need to investigate the new MVDC-based nuclear submarine power distribution system and its real-time hardware-in-the-loop (HIL) emulation to test the control systems, device stresses, etc. This paper proposes a comprehensive MVDC-based nuclear submarine power distribution system emulated in real-time on a multi-FPGA hardware platform with system-level transients (validated by Matlab/Simulink ^{) at $\text{20}\;\mu\text{s}$ time-step and device-level transients (validated by SaberRD ) at $\text{400 ns}$ time-step.}

核潜艇MVDC配电系统的全面实时硬件在环瞬态仿真

核潜艇比常规柴电潜艇具有明显的性能优势。它强大的核动力可以独立于空气运行，并且在整个25年的使用寿命中都不需要加油。工业上应用的中压直流电（MVDC）技术的最新进展将节能和极长时间的运行推向了一个新阶段，并提出了一种将小型核反应堆嵌入船内的可行解决方案。因此，有必要研究基于MVDC的新型核潜艇配电系统及其实时硬件在环（HIL）仿真，以测试控制系统，设备压力等。 ^{） 在 $ \ text {20} \; \ mu \ text {s} $时间步长和设备级别的瞬变（由SaberRD验证 ）在$ \ text {400 ns} $ 时间步长。}
