Multi‐FPGA digital hardware design for detailed large‐scale real‐time electromagnetic transient simulation of power systems
Bibliographic record
Abstract
Large‐scale electromagnetic transient simulation of power systems in real‐time using detailed modelling is computationally very demanding. This study introduces a multi‐field programmable gate array (FPGA) hardware design for this purpose. A functional decomposition method is proposed to map FPGA hardware resources to system modelling. This systematic method lends itself to fully pipelined and parallel hardware emulation of individual component models and numerical solvers, while preserving original system characteristics without the need for extraneous components to partition the system. Proof‐of‐concept is provided in terms of a 3‐FPGA and 10‐FPGA real‐time hardware emulation of a three‐phase 42‐bus and 420‐bus power systems using detailed modelling of various system components and iterative non‐linear solution on a 100 MHz FPGA clock. Real‐time results are compared with offline simulation results, and conclusions are derived on the performance and scalability of this multi‐FPGA hardware design.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
