EMULATION OF A SMALL WIND TURBINE SYSTEM WITH A SEPARATELY-EXCITED DC MACHINE
Bibliographic record
Abstract
A small wind turbine emulator based on a separately excited DC machine is described in this paper. The experimental rig consists of a PC, Lab Master I/O board, power electronics circuitry and a 3HP separately excited DC motor which drives a synchronous generator. Varying aerodynamic power of the wind turbine due to furling action and its resulting dynamics are incorporated in the emulator with the use of a PC based wind turbine model. The shaft torque of the dc motor is determined from the armature current and parameters of the DC drive obtained by experimentation. In order to reflect the inertia of a small wind turbine an inertia disk is designed and coupled to the generator shaft and separately- excited DC motor. A digital PI controller is designed which makes sure that the actual rotational speed of the motor is tracking the theoretical rotational speed of the wind turbine rotor. The system design, model used and experimental results of the small wind turbine emulator are presented in the paper.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
