Explicit formulations for constant-parameter voltage-behind-reactance interfacing of synchronous machine models
Bibliographic record
Abstract
Summary form only given. Interfacing of ac electrical machine models in power system transient simulation programs is receiving increasing attention in the literature, wherein models based on the voltage-behind-reactance (VBR) formulation have been recently proposed to achieve a direct interface with external power networks. However, synchronous machine dynamic saliency introduces time-dependent interfacing inductances in traditional VBR models, which increases the computational cost of the overall system solution. This paper presents several new explicit continuous- and discrete-time approximation techniques to eliminate dynamic saliency in VBR models and achieve a simple interfacing circuit with decoupled constant-parameter RL branches. The new models are implemented in MATLAB/Simulink and the PLECS toolbox, and are shown to offer simple and easy-to-use interface, high accuracy, and numerical efficiency as compared to the existing models. The proposed interfacing circuit and approximation techniques can find wide application in common state-variable-based transient simulation programs.

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.
