To secure a desired amount of power generation by a power generator while maintaining a desired vessel speed.SOLUTION: A vessel propulsion system 100 includes a main engine 3, a variable pitch propeller 4 and an electric power generator 5 rotatably driven by the main engine 3, and a control device 6 for controlling the main engine 3 and the variable pitch propeller 4. The control device 6 controls rotational speed of the main engine 3 and blade angle of the variable pitch propeller 4 according to target vessel speed in a first operation range stipulated based on rotational speed and output of the main engine 3 in the first operation mode for having the main engine 3 only drive the variable pitch propeller 4, and sets a second operation range by lowering upper limit of output of the first operation range according to power generation load of the electric power generator 5 and sets the target rotational speed of the main engine 3 and the target blade angle of the variable pitch propeller 4 according to the target vessel speed within the second operation range in the second operation mode where the main engine 3 drives the variable pitch propeller 4 and the power generator 5.SELECTED DRAWING: Figure 1

    【課題】所望の船速を維持しつつ、発電機による所望の発電量を確保する。【解決手段】船舶推進システム100は、主機3と、主機3によって回転駆動される可変ピッチプロペラ4及び電動発電機5と、主機3及び可変ピッチプロペラ4を制御する制御装置6とを備える。制御装置6は、主機3が可変ピッチプロペラ4だけを駆動する第1運転モードにおいては、主機3の回転速度及び出力に基づいて規定された第1運転領域内で目標船速に応じて主機3の回転速度及び可変ピッチプロペラ4の翼角を制御し、主機3が可変ピッチプロペラ4及び電動発電機5を駆動する第2運転モードにおいては、第1運転領域の出力の上限を電動発電機5の発電負荷に応じて引き下げることで第2運転領域を設定し、目標船速に応じた主機3の目標回転速度及び可変ピッチプロペラ4の目標翼角を第2運転領域内で設定する。【選択図】図1
