Comprehensive Real-Time Hardware-In-the-Loop Transient Emulation of MVDC Power Distribution System on Nuclear Submarine
Bibliographic record
Abstract
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<br> 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 20 microsecond time-step and device-level transients (validated by SaberRD) at 400 nanosecond time-step.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
