Patent

CA 2413571

A ship lock utilizes a hydraulic turbine and/or pump-turbine to regulate the discharge flow rates through the ship lock to an approximate constant value during the majority of the water transfer cycle resulting in a diminishing of total energy of head losses and to enable the recuperation of the unused hydraulic energy for generation as electricity. The difference in water levels on opposite sides of the ship lock constitutes potential hydraulic energy. By regulating the discharge, the total head losses over a given period of time diminish very significantly, thus giving an opportunity for optimization of hydraulic energy recuperation.

Une écluse utilise une turbine hydraulique et/ou une turbine à pompe pour réguler le débit d'extraction à travers l'écluse selon une valeur constante approximative durant une grande partie du cycle de transfert d'eau, ce qui diminue l'énergie totale des pertes de charge et favorise la récupération de l'énergie hydraulique non utilisée pour la production d'électricité, par exemple. La différence entre les niveaux d'eau des côtés opposés de l'écluse constitue une énergie hydraulique potentielle. Grâce à la régulation des extractions, on diminue considérablement les pertes de charge totales sur une période donnée, ce qui permet d'optimiser la récupération de l'énergie hydraulique.
