Dans une installation hydro-électrique (ou de pompage) on a en règle générale plusieurs turbines (ou pompes) connectées ensemble par un système de conduites, composé d'" embranchements " (c'est-à-dire de " branches " en parallèle) et de conduites communes. L'étude décrit un algorithme à très bonne convergence, permettant de déterminer le régime stationnaire à travers un tel embranchement, dont les branches comportent outre les conduites, des turbines, pompes, vannes, etc., réglées pour des débits quelconques.
Abstract
In a hydro-electric (or pumping) installation, as a general rule, there are several turbines (or pumps) cnnnected together by a system of conveyances, made up of "branchings" (i.e. "branches" in parallel) and conveyances in common. The study describes an algorithm with a very good convergence, enabling the stationary regime in such an branching to be determined, the branches of which contain apart from the conveyances, turbines, pumps, valves, etc. adjusted for certain flow rates.
