Abstract

The purpose of the invention is to provide a gas-electric parallel ship hybrid power system with fuel cells. The system comprises a gas machine, a fuel cell, a reversible motor and a gear case; the gear case comprises an input end, an output end and an input / output end; the output of the gas machine is connected to the input of the gear case via a permanent magnet coupler; the output / input end ofthe reversible motor is connected to the input / output end of the gear case via a clutch, the output end of the gear case is connected to a propeller, and a LNG tank is connected to a gas supply device; the gas supply device is connected to the gas machine and the fuel cell, and the fuel cell, the battery, the ship load, the inverter, and the rectifier are electrically connected to a power distribution board, and the inverter is electrically connected to the reversible motor through a frequency changer, and the reversible motor is connected to the rectifier. The various energy forms arranged bythe invention can meet the requirements of the ship under various environments and working conditions, effectively reduce the fuel consumption and emissions of the gas machine, and improve the dynamic response of the ship.

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] As a power generation device with high power generation efficiency, low environmental pollution, high specific energy, low no...
