Abstract

The purpose of the invention is to provide a dual-shaft ship hybrid power system with a fuel cell. The system comprises a diesel engine, a gas machine, a fuel cell and a storage battery; the gas machine is connected to a first reversible shaft motor; the first reversible shaft motor is connected with a gear case; the diesel engine is connected with a second reversible shaft motor; the second reversible shaft motor is connected with the gear case; the gear case is connected with two propellers; a liquefied natural gas tank is connected with a gas supply device; the gas supply device is connected with the gas machine and the fuel cell; the fuel cell, the storage battery, a ship load, an inverter and a rectifier are all electrically connected with a distributing board; the inverter is connected to the first reversible shaft motor and the second reversible shaft motor through a frequency converter, and the first reversible shaft motor and the second reversible shaft motor are electricallyconnected to the rectifier. The invention can meet the requirements of the ship under various environments and working conditions, further improve the operating efficiency of the gas machine, the diesel engine and the reversible shaft motor, and effectively reduce the fuel consumption and emission of the engine.

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] Diesel engine, as the main engine for ships in the world, has the advantages of mature technology, high thermal efficiency, good economy, and good dynamic response. However, as people pay more attention to energy issues and environmental issues, the problem of oil reserves and the emission of diesel engines cannot be ignored, especially marine diesel engines often use low-quality diesel, which leads to more serious emission problems. In addition, the continuous rise of diesel prices also makes the operation The...
