An efficient model of synchronous generator for hydraulic power plant dynamic simulations
Bibliographic record
Abstract
The paper is concerned with practical modelling of the synchronous generator (SG) as the main component of the hydroelectric power plant. The generation system under study comprises the hydraulic circuit, the speed regulator, the excitation system and the SG. Each system component is formatted into state form. The SG state model developed with field voltage as the only controlled input variable and with stator currents, field currents and stator voltages as output observed variables, includes both the saturation phenomenon and the mechanical motion. The resulting flexible SG model connected to other power plant components allows predicting various tests such as: the classical three-phase sudden short-circuit test, the field short-circuit test with the stator in open circuit and the load rejection and line-switching tests. In order to prove the effectiveness of the proposed power plant modeling framework, extensive simulations using the Matlab/Simulink program are performed and discussed for different tests and plant scenarios (automatic voltage regulator (AVR) on and off).

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.
