Abstract

The purpose of the invention is to provide a single-engine double-propeller gas-electric hybrid ship power system with a fuel cell. The system includes a gas engine, a generator, motors, the fuel cell, a storage battery, clutches, a gear case, propellers, a natural gas storage and supply device, a substation device, a shore power device, a ship power grid, and a ship load. The gas engine is connected to the gear case through the clutch. The motors and the generator are connected to the gear case through the clutches. The propellers are directly connected to output ends of the motors. An electric power source is the fuel cell, the storage battery and the generator. The single-engine double-propeller gas-electric hybrid ship power system with the fuel cell adopts a plurality of energy form arrangements, has a plurality of working modes, can meet requirements of ships in various environment and working conditions, can maintain the gas engine and the motors in a high efficiency zone all the time, reduces the fuel consumption and discharge of the ship power system, improves the power response of ships, and enlarges seaworthiness of the ships.

Description

technical field [0001] The invention relates to a ship power system, in particular to a ship hybrid power system. Background technique [0002] With the rapid rise of international oil prices and the implementation of increasingly stringent emission regulations, higher requirements are placed on the economy and emission of ships. Energy conservation and emission reduction have become an important task in the development of the national economy. Ships are high-energy-consuming means of transportation, and their energy-saving and emission-reduction technologies have become one of the hotspots of everyone's attention and research. [0003] As a future environmental strategy, we aim to reduce energy consumption and CO2, SOx, NOx and PM emissions. There are many ways to reduce pollution and emissions from ships, the best of which is the use of alternative energy sources. Natural gas as engine fuel is an inevitable trend in the development of marine engines in the future. Natura...
