Marine fuel cell hybrid propulsion system and energy control method

Abstract

The invention discloses a marine fuel cell hybrid propulsion system and an energy control method. A fuel cell and a storage battery pack jointly serve as a power source of the propulsion system, and an energy management module, the hybrid power source and a propulsion system module are connected to form the hybrid propulsion system. In the navigation process of a ship, when the power required by the ship is in the optimal power interval of the fuel cell, the fuel cell supplies power to the propulsion system module; when the power required by the ship is larger than the optimal power interval of the fuel cell, the fuel cell and the storage battery pack jointly supply power to the propulsion system module; and when the fuel cell fails or raw materials are insufficient, the storage battery pack supplies emergency power to the ship. According to the marine fuel cell hybrid propulsion system and the energy control method, pollution-free and zero emission in a real sense can be realized, andenergy utilization is optimized.

Description

technical field [0001] The invention relates to the technical field of ship power systems, in particular to a ship fuel cell hybrid propulsion system and an energy control method. Background technique [0002] Ship is a kind of means of transportation at this stage, especially in the freight industry, because it can carry a large amount of goods, it is widely used in maritime transportation. However, under the current situation of advocating intelligent ships and green oceans, the large use of traditional diesel engine-driven ships will have a great impact on the natural environment. Therefore, the development of hybrid ships is of great significance, and energy saving and environmental protection are the key points of ship power design. premise. [0003] For example, Chinese patent document CN102120488A discloses "Hybrid Ship Electric Propulsion System and Implementation Method", which uses a power battery as the main power source of the electric propulsion system and a di...

AI Technical Summary

Problems solved by technology

[0004] The present invention mainly solves the technical problems that the existing ship hybrid propulsion system cannot achieve true pollution-free, zero-emission and energy utilization can not be optimized: it provides a ship fuel cell hybrid propulsion system and an energy control method , using fuel cells and battery packs as hybrid power sources to power the propulsion system to achieve true pollution-free and zero-emission use of the ship's internal energy management module to rationally allocate fuel cell and battery pack energy according to the ship's sailing conditions supply to optimize energy utilization
