Example Embodiment

[0013] The present invention will be further described below in conjunction with the drawings and specific embodiments. It should be emphasized that the following description is only exemplary, and is not intended to limit the scope of the present invention and its application.

[0014] Such as figure 1 A distributed power system based on fuel cells and wind energy is shown, including a wind power generation system 1, an electrolyzed water system 3, and a fuel cell 10. The wind power generation system 1 includes a blade 1-1 and a motor. The blade 1-1 is connected to the motor through a mandrel, and the motor is connected to a load 11. The blade 1-1 rotates at a high speed under the action of wind, and the motor converts wind energy into electrical energy.

[0015] The electrolysis water system 3 includes N electrolysis cells 3-1 in parallel, and the N electrolysis cells 3-1 are connected in parallel to the motor and connected in parallel to the load 11. The N water supplement pip...

Abstract

The present invention relates to a distributed energy system based on a fuel cell and wind energy. When wind resources are sufficient, blades of a wind power generation system rotate at a high speed under the action of the wind, and wind energy is converted into electrical energy through a motor so as to directly supply power during a powe utilization peak period; the motor is simultaneously connected to N parallel electrolytic tanks, the electrical energy is used for electrolysis of water during a power utilization valley period, and hydrogen and oxygen which are generated through electrolysis of water are respectively stored after compression; when the wind resources are insufficient, a hydrogen storage tank and an oxygen storage tank provide hydrogen and oxygen for the fuel cell to generate electricity; and hot water generated by the fuel cell flows back to the electrolytic tanks, and hot air discharged after heat exchange in the fuel cell can replace a conventional electric heating apparatus to heat the blades when the fuel cell works so as to prevent icing of the blades. Through rational arrangement of a total energy system, large-scale wind power can be conveniently and reliably incorporated into a conventional grid, meanwhile, effective output power of the wind power generation system can be increased from 96% to 98% at a rated wind speed, and thus, the distributed energy system has significant social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, in particular to a distributed power supply system based on fuel cells and wind energy. Background technique [0002] As an important means to cope with the dual challenges of climate change and energy crisis in the new century, wind energy is currently one of the most commercialized clean energy sources. It has a good industrial foundation, obvious economic advantages, and no resource constraints of other renewable energy sources. , and will not have a major impact on the environment. However, wind energy has disadvantages such as regionality, intermittent nature, and low utilization hours. Once it is integrated into the grid, it will have an impact on the stability and safety of the grid. In order to realize the sustainable development and coordinated, safe, reliable and efficient operation of large-scale intermittent clean energy grid-connected power generation in the grid...
