System interaction studies in real-time for the Birchtree SVC
Bibliographic record
Abstract
This paper reports on the real-time power system simulator tests that were performed on the actual controls of the Birchtree SVC. The Birchtree SVC and close to 500 km of new 230-kV transmission lines are being placed in service in 2011 to accommodate the firm interconnection of a new 200 MW hydro generating facility in northern Manitoba. The real-time simulator model represented the Manitoba Hydro network in detail within approximately 300 km of the SVC including the Ponton SVC and machine dynamics of several hydro generators. The network was equivalanced outside this area. The main results verify that the two SVCs are electrically-close and required voltage regulator gain adjustment to ensure no adverse interaction. The power oscillation damping (POD) controller was shown to not work well in an islanded configuration. Rather than have dual stabilizer settings, it was decided to disable the POD when operation in the island mode was detected. The SVC controls were confirmed to be immune to severe harmonic distortion caused by geomagnetic induced current.

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.
