The present invention provides a power generation device for a direct current propulsion ship based on direct current power, and a control method therefor. The power generation device for a direct current propulsion ship, according to one embodiment of the present invention, comprises: a synchronous generator for generating alternating current voltage; an active front end (AFE) converter connected to an output terminal of the synchronous generator so as to convert the alternating current voltage into direct current voltage; and an automatic voltage regulator (AVR) for controlling a field current such that the magnetic flux of a stator of the synchronous generator is maintained at a constant magnetic flux, wherein sensor for measuring the rotational speed of the synchronous generator can be omitted.

    La présente invention concerne un dispositif de génération de puissance pour un navire de propulsion à courant continu sur la base d'une puissance en courant continu, ainsi que son procédé de commande. Le dispositif de génération de puissance pour un navire de propulsion à courant continu, selon un mode de réalisation de la présente invention, comprend : un générateur synchrone pour générer une tension de courant alternatif ; un convertisseur d'extrémité avant active (AFE) connecté à une borne de sortie du générateur synchrone de façon à convertir la tension de courant alternatif en tension de courant continu ; et un régulateur de tension automatique (AVR) pour commander un courant de champ de telle sorte que le flux magnétique d'un stator du générateur synchrone est maintenu à un flux magnétique constant, un capteur pour mesurer la vitesse de rotation du générateur synchrone pouvant être omis.
