To provide an electric power system for a ship, a ship, and use method for the electric power system for a ship capable of saving space at lower cost by configuring an inboard bus bar to be a DC bus bar.SOLUTION: An electric power system for a ship 1 for driving a propulsion device 22 by using electric energy stored in a power storage device 21 includes: a DC bus bar 25; the power storage device 21 connected to the DC bus bar 25; the propulsion device 22 connected to the DC bus bar 25; a plurality of power generators 23 connected to the DC bus bar 25; and an inboard power supply device 24 connected to the DC bus bar 25. Each of the plurality of power generators 23 is provided with a power generator 26 and a power conversion device 27 for converting AC to DC. When a battery 31 is charged, power is supplied to the power storage device 21 through the DC bus bar 25 from at least one power generator 23. When the battery 31 is discharged, power is supplied to the propulsion device 22 and the inboard power supply device 24 through the DC bus bar 25 from the power storage device 21.SELECTED DRAWING: Figure 1

    【課題】船内母線を直流母線にすることにより、より安価で、省スペース化を実現可能な船舶用電力システム、船舶、および、船舶用電力システムの使用方法を提供する。【解決手段】蓄電装置21に貯められた電気エネルギを用いて推進装置22を駆動させる船舶用電力システム1は、直流母線25と、直流母線25に接続される蓄電装置21と、直流母線25に接続される推進装置22と、直流母線25に接続される複数の発電装置23と、直流母線25に接続される船内給電装置24と、を具備する。複数の発電装置23の各々は、発電機26と、交流を直流に変換する電力変換装置27とを備える。バッテリ31の充電時には、少なくとも1つの発電装置23から、直流母線25を介して、蓄電装置21に電力が供給される。バッテリ31の放電時には、蓄電装置21から、直流母線25を介して、推進装置22および船内給電装置24に電力が供給される。【選択図】図1
