Abstract
This paper presents the real-time digital simulation of a grid-connected wind turbine generator system (WTGS) based on a doubly-fed induction generator (DFIG). A 1.5-MW WTGS is the basis for model development. First a detailed electromagnetic transient model for the WTGS is developed in the MATLAB/SIMULINK environment. This model includes the complete aerodynamic, mechanical and electrical components of the wind turbine, the back-to-back voltage source converter (VSC)-based power electronic interface, as well as the mechanical and electrical controllers of the WTGS. The overall grid-connected WTGS model was then order-reduced and implemented on a PC-cluster-based real-time digital simulator. The maximum execution time of the DFIG model and control was 5.53 mus, while that of the grid-connected WTGS was 15.375 mus. Real-time oscilloscope results are presented to illustrate the WTGS controller performance, the variable wind speed dynamics, and interaction of the WTGS with grid faults. The real-time WTGS model can be readily used for hardware-in-the-loop testing.

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
