Zusammenfassung: | Disclosed is a hybrid propulsion system capable of optimal efficiency operation, which comprises: a propulsion unit including a slipstream measurer for measuring slipstream of a propeller area, a shafting sensor for sensing the torque and speed of a driving shaft for driving a propeller, and a main engine for rotating and driving the driving shaft; an in-board power supply unit including a bogie engine for supplying power to an in-board power network, a waste heat recovery device, a shaft generator motor interworking with the driving shaft, and a battery; and a control unit controlling a final output of the main engine and switching and an output direction between the in-board power network and the in-board power supply unit in accordance with slipstream information in response to an operation mode. Accordingly, fuel consumption can be minimized by providing in-board power and ship propulsion force to allow optimal operation for each operation mode in accordance with measurement information by the slipstream measurer and the shafting sensor.
