Abstract

fetched live from OpenAlex

This paper presents a study of Temporary Overvoltage (TOV) on the Manitoba Hydro rectifier system under the proposed development of a new HVDC link and generations. The TOV assessment is based on a full load rejection of three Bipoles, which should result in the highest temporary fundamental frequency overvoltage. The detailed PSSE TOV studies include several system topologies regarding generation and transmission line connections as well as new converter ratings. The paper also discusses the relationship between the system strength described by Multi-Infeed Effective Short Circuit Ratio (MIESCR) and the TOV. A more general analytical equation for estimating TOVs was derived by introducing a multiplying factor related to Bipole parameters. The validation of the equation based on PSSE studies indicates that the revised equation could be used as a screening tool for predicting TOVs in a multi-infeed system.

Teacher imitation

Not 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.
