Title (EN) HYDRO-ELECTRIC POWER CONVERSION SYSTEM
(FR) SYSTEME DE CONVERSION D'ENERGIE HYDRO-ELECTRIQUE
Abstract:
(EN) The low head energy in for example a river flow is used to provide electrical energy by directing the water through a duct (70), and by inducing air into the duct to create an air flow which is drawn over an air turbine (76) to excite same, and thereby produce electrical energy. The air can be introduced into the flowing water in the duct by a switching arrangement to ensure that no bubbles or pockets of air travel along with the water, which impaires efficiency. The duct may be in the shape of an anti-gravity course (70) to prevent the bubbles from travelling.
(FR) On utilise l'énergie d'une faible charge de courant d'une rivière, par exemple, pour produire de l'énergie électrique en faisant circuler l'eau à travers un conduit (70) et en introduisant de l'air dans celui-ci pour créer un courant d'air attiré de façon qu'il passe par une turbine à air (76) pour l'actionner et, de ce fait, produire de l'énergie électrique. On peut introduire l'air dans l'eau s'écoulant dans le conduit au moyen d'un dispositif de commutation pour empêcher la circulation de bulles ou de poches d'air avec l'eau, ce qui diminue l'efficacité. Le conduit peut présenter un tracé (70) empêchant la circulation des bulles par gravité.
