A Computer Based System For EHV Line Monitoring And Control
Bibliographic record
Abstract
A real-time digital data-acquisition and processing system has been operating continuously since late May 78 in an Hydro-Quebec 735 kV substation. This paper describes the actual implementation and reports the operating experience. The prototype was developped in the first stage of a research project on computer-based line protection. The software is designed to accomodate (i) relaying algorithm (ii) auto verification (iii) self-evaluation and (iv) communication functions. All these functions are performed on line. Relaying algorithm consists of a one-cycle Fourier analysis and a continuous calculation of impedances. The sampling rate is controlled by the computer to synchronize to the power system frequency. Upon detection of a perturbation, five to fifty cycles of rel evant voltage and current waveform samples are "frozen" and transmitted via a phone link to IREQ main computer for permanent storage and further processing. Performances of the protection algorithm are evaluated auto matically against the actual protection system. An auto-answer modem allows the control of the remote system.

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.
