  • Power supply system
    Patent number: 11128245
    Abstract: At least one of a plurality of generators is a first generator configured such that a relationship of a generator output voltage with respect to a generator active power output from the generator to a corresponding first AC wiring portion has a predetermined first drooping characteristic. The control device is configured to generate a drive signal for a power conversion device by deciding a target value of a first control element such that a relationship of an AC wiring portion voltage with respect to a power conversion device active power output from the power conversion device to a first AC wiring portion corresponding to a first generator has a predetermined second drooping characteristic and correcting the target value of the first control element according to a DC voltage at a DC wiring portion.
    Type: Grant

    Date of Patent: September 21, 2021
    Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHA
    Inventors: Yusuke Umezu, Kazushige Sugimoto, Soichiro Bando, Naoki Yamaguchi, Kenichi Sakimoto, Kiyoshi Kimura, Suguru Takayama, Takato Uda

  • Power supply system
    Patent number: 10985560
    Abstract: Each of the plurality of generators is configured so a relationship of frequency with respect to a generator active power output by each generator to the corresponding alternating-current wiring unit has a predetermined first drooping characteristic. The plurality of power conversion devices is configured to convert alternating-current power input through each alternating-current wiring unit into direct-current power, and to convert direct-current power input through the direct-current wiring unit into alternating-current power.
