Abstract
As a result of the development of a third Bipole and additional generation in Manitoba Hydro NCS system, many of the existing station breaker ratings are exceeded. In addition, the ac faults at a single station affect all three Bipoles due to tight coupling between converter stations, which results in a large HVdc power loss. The application of a superconducting Fault Current Limiter (SFCL) in this multi-bipole HVdc system is introduced. The preliminary locations and parameters of the SFCLs were determined based on station short circuit levels and HVdc system responses. The PSS/E and PSCAD/EMTDC studies reveal that SFCLs applied in the single integrated HVdc collector system could effectively reduce the fault currents and also effectively mitigate the influence of a converter station fault on the rest of the converter stations. The impact of the SFCL's recovery time as an important parameter on system performance is discussed in the paper.

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
