Abstract

The purpose of the invention is to provide a gas-electric hybrid ship power system with generator set parallel operation. The system includes gas engines, a generator, a motor, a storage battery, a fuel cell, clutches, a gear case, a propeller, a natural gas storage and supply device, substation devices, a shore power device, a ship power grid, and a ship load. Output ends of the gas engines are connected to input ends of the gear case. The motor and the generator are connected to output ends of the gear case through the clutches. An electric power source is the storage battery, the generatorand the fuel cell. The gas-electric hybrid ship power system with the generator set parallel operation adopts a plurality of energy form arrangements, realizes a plurality of working modes by openingand closing the clutches, can meet requirements of ships in various environment and working conditions, can maintain the gas engine and the motor in a high efficiency zone all the time, reduces the fuel consumption and discharge of the gas engine, improves the power response of the 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...
