Abstract

A ship powered by an internal combustion engine (1) and an electric motor (2) connected to a propeller (3) powered by surplus electric power obtained by a thermal discharge recovery system has a controller including a feedback control section for controlling a base amount of fuel injected to the internal combustion engine (1) based on the difference between the target number of rotation of the propeller given by the operator and the real number of rotation, and a feed-forward control section having a means (25) for calculating an overall power output and a means (26) for calculating a correction in the amount of fuel injected to the internal combustion engine based on the overall power output and the number of rotation of the propeller. The base amount of fuel is corrected by subtracting the correction obtained by the feed-forward section from the base amount of fuel calculated by the feedback control section whereby preventing a rapid change in the speed of the ship due to rapid change in ship loads.

Description

technical field [0001] The present invention relates to a control device for a ship equipped with a waste heat recovery system and a ship equipped with the control device. The waste heat recovery system includes an internal combustion engine, a shaft generator connected to the internal combustion engine via a shaft, and a feedback control device that performs a rotation speed change of the internal combustion engine to a target rotation speed of the internal combustion engine based on a required fuel injection amount of the internal combustion engine. feedback control. Background technique [0002] As an exhaust heat recovery system for ships, there is a power generation system in which a steam turbine is driven by performing heat exchange with exhaust gas discharged from a main engine using exhaust gas from an engine using an exhaust gas preheater; The engine output spins a shaft generator to generate electricity to compensate for electrical loads within the vessel. These...
