Abstract
This paper proposes a new HVDC (High-Voltage DC) transmission topology, its modeling and control method, used for large doubly-fed induction generator (DFIG)-based offshore wind farms. The sending end is a line commutated converter (LCC) with a STATCOM (Static Compensator) while the receiving end is a current source inverter (CSI) using IGBTs. The STATCOM provides stator voltage support for DFIGs, as well as commutation voltage for the LCC. The LCC regulates the active power produced by DFIG wind farms, and transmits it to the onshore inverter through HVDC link. Working in constant voltage control mode, the inverter then feeds the active power into the main AC grid. Simulations verify that, as a combination of existing LCC-HVDC and VSC (Voltage Source Converter)-HVDC technologies, the proposed system not only has the black start capability, possesses fast active power dynamics, but also can provide independent reactive support to the grid.

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
