Abstract

The invention aims to provide a gas-electric hybrid type ship hybrid power system with a super capacitor. The system comprises a gas machine, the super capacitor, a propeller, a natural gas storage and supply device and a ship load. The output end of the gas machine is connected with the input end of a gearbox, and the input end of a power generator is connected with the output end of the gas machine through a belt transmission transposition; the output end of the gearbox is connected with a motor, and the super capacitor, the power generator and a storage battery serve as power sources. The arrangement of various energy forms adopted by the system can meet requirements of ships under various environments and working conditions; the super capacitor is used for storing or releasing energy when the system load is changed so as to prevent the impact of the excessively quick energy change on a power grid, the operation efficiency of the gas machine, the power generator and the motor is improved, the utilization efficiency of fuel is improved, emission is reduced, the power response of the ships is improved, the application range of the system is enlarged, and the utilization rate of the fuel is further improved.

Description

technical field [0001] The invention relates to a ship power system, in particular to a ship hybrid power system. Background technique [0002] With the rapid rise of international oil prices and the implementation of increasingly stringent emission regulations, higher requirements are placed on the economy and emission of ships. Energy conservation and emission reduction have become an important task in the development of the national economy. Ships are means of transportation with high energy consumption, and their energy-saving and emission-reduction technologies have become one of the hot spots of everyone's attention and research. [0003] We aim to reduce energy consumption and CO2, SOx, NOx and PM emissions. There are many ways to reduce pollution and emissions from ships, the best of which is the use of alternative energy sources. Using natural gas as engine fuel is an inevitable trend in the development of marine engines in the future. Natural gas has the advantag...
