Abstract
Advancements in renewable energy technologies and increasing demand for reliable and sustainable power solutions in remote areas are driving rapid growth of isolated microgrids (IMGs) powered by inverter-based distributed generation units (IBDGs). However, traditional overcurrent protection schemes no longer work for the short circuit fault (SCF) protection in these IMGs with IBDGs due to significant differences between SCF current characteristics of IBDGs and conventional synchronous generators, necessitating the development of new protection schemes. This paper proposes a new pilot protection scheme for the SCF protection based on variations of the positive sequence current at both ends of a protected power line. The proposed scheme provides fast and reliable primary and backup protection for SCFs, requiring only the exchange of status signals between protective relays. This approach avoids the communication burden and time synchronization requirements, typically associated with the differential protection.

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
