Wind turbine multiphase operational trajectory in an all‐DC wind generation system
Bibliographic record
Abstract
An operational trajectory and a control scheme for wind turbine generators (WTGs) in an all‐DC wind system is proposed in this study. The wind turbine includes a multiphase hybrid generator (HG) and a passive rectification stage. The WTG output is sent to an off‐shore substation using a medium‐voltage DC (MVDC) collector grid. The off‐shore substation is connected to the terrestrial grid using a high‐voltage DC (HVDC) transmission grid. The multiphase HG employs a two‐rotor topology and facilitates an active control over the wind turbine power and voltage. The proposed control scheme allows for a variable MVDC grid voltage while maintaining a wind turbine desired power under maximum power point tracking. The wind turbine trajectory is a path that wind turbine operates on as the wind velocity varies, and it is defined by HG control current, MVDC grid voltage and wind turbine power. To present the effectiveness of the proposed control and verifying the analytical model of wind turbine trajectory, a simulation platform is developed and results are presented.

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.
