Abstract

fetched live from OpenAlex

Power systems are interconnected for enhancing the availability of power supply to the customers and for reducing the prices charged to them. A natural consequence of this practice is that the interconnected power systems are likely to swing following faults and other disturbing events. Power swing relays are traditionally used to block distance relays from tripping line circuit breakers if the swing is not likely to cause dynamic instability but open the interconnecting lines if the systems are likely to become unstable. This is achieved by using delay timers but deciding on the delays is a very difficult, complex and judgmental issue. This paper presents a new approach for use in out-of-step relays. The technique is based on the well known equal area criterion. The basis of the protection technique is described in the paper. The technique is able to correctly identify swings that are likely to result in dynamic instability.

Full frame distilled prediction

Teacher imitation

Not 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.
