Ship direct current networking system adopting fuel cell and ship applying same

Abstract

The invention discloses a ship direct current networking system adopting fuel cells and a ship applying the same. The ship direct current networking system adopting fuel cells has the working principle that a fuel cell stack is regarded as a main power device of the ship, and a storage battery is regarded as the auxiliary power supply device, the storage battery and the fuel cell stack form a shipdirect current network; the electric energy generated by a wind generating set is output to an electrolytic tank to produce hydrogen by electrolysis of seawater; the surplus electric energy is storedin the storage battery; the electric energy generated by photovoltaic cells is output to the electrolytic tank to produce the hydrogen by electrolysis of the seawater; and the surplus electric energyis stored in the storage battery, and the wind energy and solar energy are used to convert the electric energy into clean hydrogen energy, so that the power of the power supply of the ship power system is all from new energy, and the problem of wind and light abandonment is solved to a certain extent, the utilization efficiency of new energy is improved, and the operation cost of the ship is reduced. According to the ship direct current networking system adopting fuel cells and the ship applying the same, wind power generation and photovoltaic power generation are linked through hydrogen production from electrolyzed water, so that the grid connection control of wind power generation and photovoltaic power generation is omitted, and the grid connection consumption of ship power grid for new energy generation does not need to be considered.

Description

technical field

[0001] The invention relates to a ship direct current networking system and a ship applying the system, in particular to a ship direct current networking system using fuel cells and a ship applying the system. Background technique

[0002] With the continuous increase of energy demand, traditional fossil energy can no longer meet people's needs. And based on the requirements for environmental protection, clean new energy power generation is becoming more and more important. The power generation devices of the traditional ship power system basically use fossil energy as raw materials, but the cost of fossil energy continues to rise, which makes the operating cost of the ship also continue to increase, and the ocean is rich in renewable energy such as solar energy and wind energy, which is reasonable The development and utilization of these renewable resources help to reduce the operating costs of ships, and are of great significance to the protection of the m...
