Abstract

The invention provides a diesel electric parallel ship hybrid system with a fuel cell. The system is composed of a diesel engine, a gas machine, reversible motors, the fuel cell, a storage battery, apermanent magnet coupler, a clutch, a gear box, a propeller, a natural gas storage supply device, an inverter, a frequency converter, a rectifier and a power distribution board. The system is characterized in that the diesel engine and the gas machine are connected to the gear box through the permanent magnet coupler, the two reversible motors are connected to the gear box through the clutch, anda power source includes the fuel cell and the storage battery. The arrangement of various energy forms adopted by the system can meet the requirements of a ship under various environments and workingconditions, the operating efficiency of the diesel engine, the gas machine and the reversible motors is further increased, the fuel consumption and emissions of an engine are effectively reduced, shipdynamic response is improved, and the system has a wide application range.

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...
