Abstract

The invention provides a single-engine single-propeller type gas-electric hybrid ship power system. The single-engine single-propeller type gas-electric hybrid ship power system comprises a gas engine, a storage battery and a gearbox, the output end of the gas engine is connected with the input end of the gearbox through a permanent magnet coupler, the output/input ends of a reversible motor are connected with the input/output ends of the gearbox through a clutch, and the output end of the gearbox is connected with a propeller. A liquefied natural gas tank is connected with a gas supply devicein a gas mode, the gas supply device communicates with the interior of 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 motor through a frequency converter, and the reversible motor is electrically connected with the rectifier. The layout of various energy forms adopted by the single-engine single-propeller type gas-electric hybrid ship power system can meet the needs of ships in various environments and operating conditions, further improves the operation efficiency of the gasengine and the reversible motor, effectively reduces fuel consumption and emission 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 invention relates to a power system, specifically a ship power system. Background technique [0002] With the increasingly severe energy and environmental problems in my country, and the rapid rise in international oil prices, this has put forward higher requirements on the economy and emissions of ships, and has made ship energy-saving and emission-reduction technologies a hot spot for everyone’s attention and research. one. [0003] As the fuel of the engine, natural gas is an inevitable trend in the development of ship engines in the future. Natural gas has the advantages of environmental protection, economy, safety and reliability. However, due to 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 forefront of future ship technology research, with good economy, maneuverability, safety,...
