Title:
POWER GENERATION SYSTEM AND ELECTRIC DRIVE SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/181954
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a power generation system capable of suppressing fluctuations in a DC voltage obtained from a main winding and a DC voltage obtained from an auxiliary winding of a two-winding induction generator with a single power converter. For this purpose, according to the present invention, a control device calculates a state quantity that changes in accordance with fluctuations in the required power of a load connected to a rectifier or a power converter, calculates a first voltage correction value for compensating for a fluctuation in a first DC voltage and a second voltage correction value for compensating for a fluctuation in a second DC voltage, on the basis of the state quantity, adds a first voltage correction value to a command value of the first DC voltage, and adds a second voltage correction value to a command value of the second DC voltage.
