Abstract
Unified power quality conditioner (UPQC) is a kind of comprehensive power quality compensation equipment with complex circuit and structure. Starting UPQC involves the establishment of the DC side capacitance voltage, logical sequence of series, parallel compensator and load, namely each part of UPQC must have a certain of start time sequence and logic control strategy. This paper discusses three establishing methods of the capacitor voltage on DC side of UPQC, which can be considered as DC power, and analyzes their advantages and disadvantages, too. Then the control logic of UPQC starting, namely the order of power supply, series and parallel compensator, and load, is discussed based on the different capacitor voltage establishment methods. The reason of adopting these switching sequences is analyzed and the detailed start logic diagram is drawn. Finally, different switching sequences are simulated by MATLAB/Simulink. The simulation results show that the proposed strategy is effective. This work is supported by National Natural Science Foundation of China (No. 50807049).

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
