Mathematical Schemes to Linearize Operating Times of Overcurrent Relays by Sequentially Fixing Plug Settings and Time Multiplier Settings
Bibliographic record
Abstract
Nowadays, many studies have been presented in the literature to solve various optimal relay coordination (ORC) problems. These highly constrained nonlinear nonconvex optimization problems are commonly solved using evolutionary algorithms (EAs). For online applications, where the processing speed is very crucial, some studies suggest using different types of linear programming (LP), including simplex and interior-point methods, while others suggest hybridizing both EAs and LPs. For these approaches, the ANSI/IEEE and IEC/BS standard models used to calculate the operating times of overcurrent relays (OCRs) are linearized by just fixing their plug settings (PS) and varying time multiplier settings (TMS). This study presents another way to linearize these models by doing the opposite where TMS are fixed and PS are varied for both standard models. These linearized models can be used to effectively tune the objective functions of ORC problems to achieve both performance criteria; the solution quality and the processing speed.

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.
