A large scale PWM solid state synchronous condenser
Bibliographic record
Abstract
The description, steady-state analysis, and the closed-loop control design of a microcontroller-based large-scale pulsewidth-modulated solid-state synchronous condenser (PWM-SSSC) for reactive power compensation are presented. The key advantage of PWM-SSSC over its predecessors is the fact that large passive magnetic components are replaced by silicon. This provides a more compact and efficient systems at a cheaper price. A series of PWM switching patterns in the low-switching-frequency range (F/sub SW/<500 Hz), which are most suitable for high-power gate turn-off (GTO) thyristors, is presented. Formulations and solutions of the Newton-Raphson method for possible low-switching-frequency PWM patterns, performance comparisons for multiple solutions, different control strategies, and the filter design are presented. Cumbersome z-domain methods for pulsed stability analysis are completely avoided by using direct s-domain computations. A systematic approach for tuning the controller parameters is introduced by extending the concept of absolute stability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
