PROBLEM TO BE SOLVED: To achieve a highly efficient energy consumption of a power generating system for a ship that drives a power generator by a main engine.SOLUTION: A power generating system for a ship that moves by driving a propeller 5 with a main engine 1 includes a main power generator 2 to be driven by the main engine 1, an auxiliary power generator 4 to be driven by an auxiliary engine 3, a binary power generator 11 to be driven by exhaust heat from the main engine, a propeller shaft idling power generator 50, a wind power generator 60, and a rolling power generator 70. An alternative current AC2 from the main power generator 2 is supplied via a PWM power supply 25 to a bus 26 as a stable alternative current AC1. The alternative currents AC2 from the power generator 50, 60, and 70 are converted into direct currents DC through a PWM power supply. And then, the direct currents DC are charged in a lithium-ion battery 40, and supplied from the battery, as required, to the power supply to the bus as alternative currents AC1.

    【課題】主機関で発電装置を駆動する船舶の発電システムにおいてエネルギー消費の効率化を実現する。【解決手段】主機関1でプロペラ5を駆動して推進する船舶の船舶用発電システムは、主機関1で駆動される主発電装置2と、補機関3で駆動される補機発電装置4と、主機関の排熱で駆動されるバイナリー発電装置11と、プロペラ軸遊転発電装置50と、風力発電装置60と、ローリング発電装置70を有している。主発電装置2からの交流AC2 はPWM 電源装置25を経て安定した交流AC1 としてバス26に供給される。各発電装置50,60,70からの交流AC2 はPWM 電源装置で直流DCとなってリチウムイオン電池40に充電され、必要時に電池から電源装置に供給され交流AC1 となってバスに供給される。【選択図】図1
