Abstract
A real-time transient simulation of nonlinear elements in transmission networks requires significant computational power. This paper proposes an iterative nonlinear transient solver on a field-programmable gate array. The parallel solver, based on the compensation method and the Newton-Raphson algorithm (continuous and piecewise), is entirely implemented in Very high speed integrated circuit Hardware Description Language. It also involves sparsity techniques, deeply pipelined arithmetic floating-point processing, and parallel Gauss-Jordan elimination. To validate the new solver, two case studies are simulated in real time: surge arrester transients in a series-compensated line and ferroresonance transients in a transformer, with time steps of 5 and 3 μs, respectively. The captured real-time oscilloscope results demonstrate high accuracy of the simulator in comparison to the offline simulation of the original system in the ATP version of electromagnetic transient program.

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 it
