Abstract
The synchronous generator is a fundamental component in the power grid and therefore, requires intelligent protection systems to ensure safe and reliable operation.This study aims to design a multifunctional intelligent protection system based on the generator capability curve and the generator's inlet air temperature.The methodology involves using MATLAB/Simulink to simulate a model consisting of a synchronous generator connected to a power transformer and an infinite busbar.The main technique used is the Fuzzy Inference System (FIS), which evaluates performance deviations and their severity, enabling protection decisions that adapt to the cooling air temperature.The system also integrates multifunctional protection that includes various protection mechanisms for the generator.The key findings reveal a significant impact of the generator's inlet air temperature on generator performance.It was shown that an increase in the cooling air temperature may cause the generator to operate beyond the limits of the capability curve, even without exceeding conventional protection thresholds.The proposed system activates protection only when truly necessary and automatically adjusts protection settings based on operating conditions, especially temperature fluctuations.This design offers a practical and scalable solution for protection systems, enhancing reliability and minimizing operational and maintenance expenses, and reducing unexpected failures.

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
