Abstract
(EN)
The purpose of the invention is to prevent current from flowing from an inverter to a main power generator to reduce the loss of the main power generator, thereby improving the reliability of a power generation system. The power generation system comprises: a power source; a power generator driven by the power source; a first breaker provided between the power generator and an AC system; a power conversion unit connected between the power generator and the first breaker; a second breaker provided between the first breaker and the power conversion unit; and a controller for controlling the deblocking of the power conversion unit and the opening and closing of the first and second breakers. In the power generation system, the controller is configured such that, when outputting a command for deblocking the power conversion unit while the first and second breakers are open, the controller issues a command for closing the second breaker after issuing a command for closing the first breaker.

La présente invention vise à empêcher le courant de passer d'un onduleur à un générateur d'énergie principal afin de réduire la perte du générateur d'énergie principal, en améliorant ainsi la fiabilité d'un système générateur d'énergie. Le système générateur d'énergie comprend : une source d'énergie ; un générateur d'énergie entraîné par la source d'énergie ; un premier disjoncteur placé entre le générateur d'énergie et un système à courant alternatif ; une unité de conversion d'énergie reliée entre le générateur d'énergie et le premier disjoncteur; un second disjoncteur placé entre le premier disjoncteur et l'unité de conversion d'énergie ; et une unité de commande servant à commander le déblocage de l'unité de conversion d'énergie, ainsi que l'ouverture et la fermeture des premier et second disjoncteurs. Dans le système générateur d'énergie, l'unité de commande est conçue de telle sorte que, lorsqu'elle délivre une commande pour débloquer l'unité de conversion d'énergie tandis que les premier et second disjoncteurs sont ouverts, l'unité de commande délivre une commande pour fermer le second disjoncteur après avoir délivre une commande pour fermer le premier disjoncteur.
