Abstract

The invention provides a single-engine three-propeller type air-electric hybrid ship power system. The single-engine three-propeller type air-electric hybrid ship power system comprises a gas engine,a storage battery and a reversible shaft-driven motor. The output end of the gas engine is connected with the input end of the reversible shaft-driven motor through a permanent magnet coupler, the output end of the reversible shaft-driven motor is connected with propellers though a clutch, a liquefied natural gas tank is connected with a gas supply device, and the gas supply device is connected with the gas engine. The storage battery, ship load, an inverter and a rectifier are all connected to a distribution board, the inverter is connected with the reversible shaft-driven motor, a first thruster and a second thruster through a frequency converter, and the reversible shaft-driven motor is connected with the rectifier. The layout of various energy forms adopted by the single-engine three-propeller type air-electric hybrid ship power system can meet the needs of ships in various environments and operating conditions, further improves the operating efficiency of the gas engine and the reversible shaft-driven motor, effectively reduces the fuel consumption and emissions of the gas engine, improves the dynamic response of the ships simultaneously, and the system has a wide range of application.

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...
