Embodiment 2
[0100] Embodiment 2: A hybrid power ship energy efficiency predictive control method
[0101]The relationship between the mechanical balance and energy conservation of a ship’s navigation is as follows: the changing working conditions of the ship during navigation are complex. In addition to the constant change of the ship’s own speed, navigational environmental factors such as wind, current, and water depth, as well as loading conditions such as draft and pitch angle, etc. Factors are also changing all the time, making the load on the ship's propulsion system constantly changing. Generally speaking, in order to overcome the changes in ship resistance caused by these load changes, the engine in the ship's hybrid power system needs to burn a certain amount of fuel, the battery pack needs to output a certain amount of electric energy, and the hybrid power module generates a certain amount of power. The power transmission of the tank is finally used to turn the propeller and gene...
