Title:
排熱回収システムを備えた船舶推進システム
Document Type and Number:
Japanese Patent JP6542065
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a ship propulsion system having an exhaust heat recovery system capable of generating a switch signal quickly even when an existing switch signal generation system is adopted, and stopping an operation of a shaft generator-motor when the switch signal is not output due to wire disconnection, a failure, or the like.SOLUTION: A control signal generation unit 23 outputs a control signal as a continuous signal for a prescribed time longer than a switch preparation time when output power or input power measured by a power measurement unit 41 is smaller than prescribed switch preparation power, and then stops the output of the control signal. When a switch operation is performed, because the continuous control signal is input to an input time accumulation unit 45, an accumulation time reaches the switch preparation time in a shorter time as compared with a case of inputting a control signal having a short pulse width. By making the control signal a continuous signal, the accumulation time can be accumulated continuously, and thus a switch signal can be generated quickly.SELECTED DRAWING: Figure 1
