Hydro-Québec Experience with Discharge Measurement in Short Converging
Bibliographic record
Abstract
Hydro-Québec performs discharge measurement for its low head power plants with the Current Meter method since a long time. Most of these measurements are done in short converging intake. The test procedure dev eloped in t he last fifteen years allows the measurement to be done in a short period of time compared to what was used before. The discharge measurement is made for commissioning or for plant operation. Hydro-Québec has done a dis charge measurement with the Acoustic Scintillation method for the first ti me in 1997. The resu lts of this m ethod were compared with t he Current Meter measurements done in the inta ke. Since the results were encouragin g, Hydro-Québec has done comparat ive tests between t hese two methods in four other power plants in order to evaluate the accura cy of the Acoustic Scintillation method for absolute discharge measurement. More recently, a comparative tests have been done between the AS method and the Pressure-time method. The Acoustic Scintillation measurement is done by in stalling the transducers on the frame that supports the current meters. This has the advantage of reducing the cost and the time of the tests..

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.
