Abstract

The purpose of the present invention is to provide a hybrid power system with two engines and three blades for a ship with composite energy storage, including a gas engine, a generator, an electric motor, a pod propeller, and a natural gas storage and supply device. The output of the gas engine is connected to the input of the gearbox, the input of the generator is connected to the output of the gearbox, the output of the gearbox is connected to the motor, the propeller is connected to the output of the motor, the pod propeller is connected to the ship power grid, and the power source is super Capacitors, fuel cells, generators and batteries. When the load of the system in the present invention changes, the energy can be stored or released rapidly, preventing the impact of too fast energy change on the power grid, improving the operating efficiency of gas engines, generators and motors, improving the utilization efficiency of fuel and reducing emissions, and improving the efficiency of ships. The dynamic response improves the application range of the system, and the fuel utilization rate has been further improved.

Description

Technical field[0001]The present invention relates to a ship power system, specifically a ship hybrid system.Background technique[0002]With the rapid rise in international oil prices, and the implementation of increasing strict emission regulations, this has put forward higher requirements for ships, and energy conservation and emission reduction has become an important task in the development of national economic development. Ships are high-energy transportation tools, and its energy saving and emission reduction technology has become one of the hotspots of everyone concerned and studies.[0003]As a future environmental strategy, we target energy consumption and reduce CO2, SOX, NOx, and PM. There are many ways to reduce ship pollution and emissions, and the best way is to use alternative energy sources. As the fuel of natural gas is the inevitable trend of future ship engine development, natural gas has green environmental, affordable, and safe and reliable advantages. However, the...
