Title:
POWER GENERATION DEVICE FOR DIRECT CURRENT PROPULSION SHIP, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/096535
Kind Code:
A1
Abstract:
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.
