Patent

CA 2754842

The invention concerns a method for the operation of an underwater powerplant comprising a water turbine for purposes of absorbing kinetic energy from a flow of water; an electrical generator with converter feed, whose generator rotor is connected in a torsionally rigid manner with the water turbine, wherein the invention is characterised in that in normal operation a first frequency converter is used for purposes of converter feed, and in the braking operation at least one second frequency converter, or one component of a second frequency converter, is connected into the circuit and synchronised with the first frequency converter, in order to execute with the latter in a combined manner a converter feed to the electrical generator, which generates a generator torque braking the water turbine.

L'invention concerne un procédé permettant de faire fonctionner une centrale électrique sous-marine comprenant une turbine hydraulique absorbant l'énergie cinétique d'un flux hydraulique ; un générateur électrique équipé d'une alimentation par convertisseur et dont le rotor de générateur est relié solidaire en rotation à la turbine hydraulique. L'invention est caractérisée en ce qu'en mode normal, un premier convertisseur de fréquence est utilisé pour l'alimentation par convertisseur, et en mode freinage, au moins un second convertisseur de fréquence ou un élément d'un second convertisseur de fréquence est mis en circuit et synchronisé avec le premier convertisseur de fréquence pour réaliser, en combinaison avec celui-ci, une alimentation par convertisseur du générateur électrique, qui produit un couple du générateur freinant la turbine hydraulique.
