Constant-Parameter Phase-Domain Synchronous Machine Modeling Considering Main Flux Saturation for EMTP-Type Solution
Bibliographic record
Abstract
The recently proposed state-of-the-art saturable voltage-behind-reactance (VBR) and phase-domain (PD) synchronous machine models offer improved numerical accuracy and stability compared to the classical <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">qd</i>0 models in electromagnetic transient (EMT or EMTP)-type solution. However, these new models are interfaced with the external network through a variable-parameter (i.e., both rotor-position- and saturation-segment-dependent) interfacing circuit, necessitating refactorizing the entire system conductance matrix at each time step and hindering computational efficiency. This paper extends the previous work by proposing new saturable constant-parameter phase-domain (CPPD) synchronous machine models possessing constant interfacing circuits. The proposed CPPD models are demonstrated in MATLAB and PSCAD/EMTDC and have numerical accuracy similar to other state-of-the-art models while providing considerable computational savings.

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.
