RTDS/RSCAD Type-3 Doubly-Fed Induction Wind Turbine Generator Model: Internship Report
Bibliographic record
Abstract
In the future, it is expected that the European Power Grid will be integrated with several sources of renewable energy producers (mainly wind/solar), alternating their maximum/minimum production periods per year. All involved parts of the European Power System (generation and consumption units) will increasingly be connected to the network utilizing power electronic devices. This will lead to technical challenges due to a dramatic reduction of rotational inertia in the system (specifically, due to the phase-out of conventional generation units with large synchronous machines) to guarantee, despite these potential inertia issues, stability at 50 Hz. The MIGRATE Project has the goal of developing solutions to ensure grid stability, control and security and quality of supply. In this manner, a Type-3 Doubly-Fed Induction Generator (DFIG) Wind Turbine (WT) Model was implemented in the Real-Time Digital System (RTDS) Power System Simulator to help the German Transmission System Operator (TSO) TenneT GmbH to analyze such phenomena with a real-time simulation model. The wind generator model provides a representation of a complex electro-mechanical system and portraits the controls, electrical and mechanical dynamics of the wind generators for conducting Electromagnetic Transient (EMT) simulations. First, it was learned how to set up simple power systems models in RTDS. Then, a translation/resemblance of an already-existing wind generator model elaborated in Manitoba HVDC Research Centre's PSCAD software tool platform was done into the RTDS domain. The final task was to validate the RTDS models, by comparing the time responses obtained in both PSCAD and RTDS. Overall, the expected goal of the internship, which was to synthesize all the acquired data from the PSCAD models to translate and migrate such models into RSCAD models ready for the use in the RTDS, was achieved.

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.
