Abstract

The purpose of the invention is to provide a dual-engine dual-oar gas-electric hybrid ship power system. The whole system is composed of gas engines, reversible motors, a storage battery, a permanentmagnetic coupler, clutches, a gear case, a propeller, a natural gas storage and supply device, an inverter, a frequency converter, a rectifier and a distributing board. The main features of the systemare as follows: two gas engines are connected to the gear case through the permanent magnet coupler, and two reversible motors are connected to the gear case through the clutches, and the power source is the storage battery. The arrangement of various energy forms adopted by the invention can meet the requirements of the ship under various environments and working conditions, further improve theoperating efficiency of the gas machine and the reversible motor, and effectively reduce the fuel consumption and discharge of the gas machine. At the same time, the dynamic response of the ship is improved, and the system has a wide range of applications.

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] Natural gas as engine fuel is an inevitable trend in the development of marine engines in the future. Natural gas has the advantages of environmental protection, economical benefits, safety and reliability. However, limited by 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 frontier of future ship technology research, and has the advantages ...
