Abstract
Due to the fast-growing presence of VSC technology on the market and advancements including reduced losses, ability to operate at higher currents and using overhead lines, preliminary studies were undertaken to evaluate the feasibility of using VSC technology for the third HVdc Bipole III planned for Manitoba. Manitoba currently has two conventional LCC HVdc Bipoles I and II. Studies showed a VSC link to be technically feasible for Bipole III and would likely eliminate the need for 1000 MVA of new synchronous condensers. In comparison to a conventional LCC link, a VSC link showed improvement in system performance, particularly for frequency dips, during remote faults in the southern system (at the inverter end). Worse performance was noted for VSC DC overhead line faults, but results were still within the system acceptance criteria. A brief look at replacing Bipoles I and II with VSC technology also showed promising results, with the likelihood of being able to retire some of the existing synchronous condensers currently needed at the inverters. The nature of the results warrants future study and consideration of VSC technology for HVdc transmission in Manitoba.

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
