Abstract
FACTS (flexible AC transmission system) devices such as static compensators (STATCOMs) have long been used to solve utility voltage problems. Generally these have been on large-scale installations on interconnected systems providing economies of scale benefits for the utilities. Recent developments and availability of smaller capacity, modular STATCOMs have proved to be just as useful for utilities in addressing a wider array of problems-from voltage regulation of weak transmission systems to multiple just-in-time installations to prevent voltage collapse and improve system stability and reliability. BC Hydro, Vancouver Canada, recently installed a small STATCOM, an 8 MVA D-VAR/sup /spl trade// device, in their system at Fort St. James substation to prevent voltage collapse in the 66-kV long radial system and as a means to defer costly transmission reinforcement. This paper outlines the system analysis, procurement, installation and performance of the D-VAR at Fort St. James along with modeling and other applications of small STATCOM devices such as D-VAR for transmission and distribution applications.

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
