Improved Algebraic-Loop Relaxation in CPVBR Models of Synchronous Machines Under Power Electronic Switching
Bibliographic record
Abstract
Constant parameter voltage-behind-reactance models of salient pole synchronous machines have been recently proposed for efficient interfacing in state-variable-based simulation programs. Therein, a constant and decoupled RL interfacing circuit is achieved using a low-pass filter (LPF) approximation that relaxes an algebraic-loop making the model explicit. However, in machine-converter systems, the ac currents and voltages contain harmonics due to switching, which necessitates the use of stiff poles in the LPF resulting in slow simulations. This letter proposes using a band-pass filter (BPF) that may be tuned depending on the switching harmonics of interest. The proposed hybrid LPF-BPF method allows the use of nonstiff poles and reduces the computational burden without compromising numerical accuracy as opposed to the conventional method.

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; a candidate call from one teacher head, not a consensus.
