ELECTRIC POWER SYSTEM OF MARINE VESSEL
(FR)
SYSTÈME D'ALIMENTATION ÉLECTRIQUE D'UN NAVIRE
Abstract:
(EN)
The present disclosure describes an electric power system of a marine vessel. The electric power system comprises a variable-frequency power generator system for generating power to a variable-frequency power network at a variable frequency selected from a set operating frequency range, a constant-frequency power network for transferring power at a desired, constant frequency, a doubly-fed machine comprising a stator with a stator winding and a rotor with a rotor winding, wherein one of the variable-frequency and constant-frequency power network is connected to the stator winding and the other is connected to the rotor winding, and a motor drive comprising an auxiliary electric motor connected to the rotor of the doubly-fed machine, wherein the motor drive is configured to control the rotation of the auxiliary motor in response to a difference between the variable frequency of the variable frequency power generator and the desired, constant frequency of the power network.
(FR)
La présente invention concerne un système d'alimentation électrique d'un navire. Le système d'alimentation électrique comprend un système de générateur d'énergie à fréquence variable pour générer de l'énergie vers un réseau électrique à fréquence variable à une fréquence variable sélectionnée à partir d'une plage de fréquences de fonctionnement définie, un réseau électrique à fréquence constante pour transférer de l'énergie à une fréquence constante souhaitée, une machine à double alimentation comprenant un stator avec un enroulement de stator et un rotor avec un enroulement de rotor, l'un des réseaux électriques à fréquence variable et à fréquence constante étant connecté à l'enroulement de stator et l'autre étant connecté à l'enroulement de rotor, et un entraînement de moteur comprenant un moteur électrique auxiliaire connecté au rotor de la machine à double alimentation, l'entraînement de moteur étant configuré pour commander la rotation du moteur auxiliaire en réponse à une différence entre la fréquence variable du générateur d'énergie à fréquence variable et la fréquence constante souhaitée du réseau électrique.
