Problems solved by technology

Theoretically, when a ship sails in still water with infinite water depth, there is a stable optimal speed that can minimize the energy consumption of the ship. However, due to the influence of the navigation environment and ship loading conditions, the optimal speed will change accordingly.

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...

Abstract

The invention discloses an energy efficiency prediction control system and method for a hybrid power ship. The system comprises a fuel flow meter, a battery management system, an axial power meter, anaxial tachometer, a Doppler velocimeter, a depth finder, a meteorological sensor, a positioning and speed measuring module, a draught sensor, a gyroscope, an acquisition card and an industrial computer. According to the method, an acquisition card transmits oil consumption, power consumption, shaft power, shaft rotating speed, channel water flow speed, channel water depth, stormy wave grade, navigation position, ground navigation speed, draught and trim angle to an industrial computer; the industrial computer calculates the ship suggested navigational speed through a navigational speed optimization model of the energy efficiency prediction control unit, calculates the ship required power through a power prediction model, calculates the optimal output power of the engine and the battery pack and the optimal propeller rotating speed through a power dynamic management model, and further displays the optimal output power and the optimal propeller rotating speed in real time through an energy efficiency auxiliary decision-making unit. The method can guide efficient and economical navigation of a hybrid power ship.

Description

technical field [0001] The invention relates to the field of energy efficiency of new energy ships, in particular to an energy efficiency prediction control system and method for hybrid ships. Background technique [0002] Global warming and greenhouse gas emissions have always attracted much attention. As a major greenhouse gas emitter, the shipping industry has faced enormous pressure from the public and environmental protection organizations in recent years. With the development of new ship energy technology and industrial control technology, hybrid ships have been widely used. [0003] For a long time, the research on the energy saving of hybrid ships has mainly focused on hybrid matching, energy-saving devices and so on. However, from the perspective of ship operation, optimizing the power output of the hybrid system is a very effective way to reduce energy consumption and improve energy efficiency. Theoretically, when a ship sails in still water with infinite water d...
