A wide range frequency adaptive synchronization system for monitoring and control of power systems
Bibliographic record
Abstract
A three phase synchronization system suitable for control and monitoring of power systems applications is presented. The Positive Sequence Filter Synchronization System (PSF-SS) is frequency adaptive and provides real time frequency, amplitude and phase estimates of the extracted positive sequence component. The PSF-SS is capable of operating over a wide range of frequencies (40-800Hz), and in the presence of significant input signal distortion (THD≤100%). The PSF-SS is capable of achieving parameter estimations within 0.5% of the nominal value for worst case scenarios. The system employs adaptive filtering techniques that offer a high degree of immunity to harmonics, inter-harmonics and notch-types disturbances over the full range of operation. In the event of input transients such as balanced/unbalanced amplitude sags and swells, balanced/unbalanced phase steps and positive/negative frequency ramps (≤250Hz/sec), the system achieves a worst case transient response time of 2 cycles of the input period. The PSF-SS is implemented as a proof of concept on a field programmable gate array. The proposed system has the highest frequency ramp tracking capability of any positive sequence synchronization system developed to date.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
