Abstract

The invention aims at providing a dual-shaft type gas-electric hybrid ship power system. The whole dual-shaft type gas-electric hybrid ship power system comprises a gas machine, a reversible shaft driven motor, a storage battery, a permanent magnet coupler, a clutch, a gearbox, a propeller, a natural gas storage and supply device, an inverter, a frequency converter, a rectifier and a switchboard.The dual-shaft type gas-electric hybrid ship power system is mainly characterized in that the gas machine is connected with the reversible shaft driven motor through the permanent magnet coupler; thereversible shaft driven motor is connected with the gearbox through the clutch; and the power source is the storage battery. According to the dual-shaft type gas-electric hybrid ship power system, theadopted layout of multiple energy forms can meet demands of a ship under various environments and working conditions, the operation efficiency of the gas machine and the reversible shaft driven motoris further enhanced, the fuel consumption and emission of the gas machine are effectively reduced, the power response of the ship is improved and the application range of the system is wide.

Description

technical field [0001] The present invention relates to a power system, specifically a ship power system. Background technique [0002] With the increasingly serious energy and environmental problems in our country and the rapid rise of international oil prices, higher requirements are placed on the economy and emission of ships, and the energy-saving and emission-reduction technology of ships has become a hot spot of everyone's attention and research. one. [0003] Natural gas as engine fuel is an inevitable trend in the development of marine engines in the future. Natural gas has the advantages of environmental protection, economical benefits, safety and reliability. However, limited by the low technical level of natural gas engines at this stage, natural gas engines have disadvantages such as poor dynamic response and insufficient power. [0004] The pure electric ship electric propulsion system is the frontier of future ship technology research, and has the advantages ...
