Title:
POWER CONVERSION DEVICE AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/233456
Kind Code:
A1
Abstract:
This power conversion device (200) comprises a power converter (20) and a control device (100). The control device includes: a DC voltage control unit (52) that generates an effective power command value on the basis of a DC voltage command value and the DC voltage of a power storage element; a power generator simulating unit (60) that generates a first angular frequency by simulating the characteristics of a synchronous power generator on the basis of the effective power command value and the effective power of a power grid; a feed forward control unit (80) that generates a feed forward command value by executing feed forward computation on the effective power command value; a phase generating unit (85) that generates a reference phase of the output power of the power converter on the basis of the first angular frequency and the feed forward command value; and a signal generating unit (103) that generates a control signal for the power converter on the basis of the reference phase and a reference voltage command value.
