Abstract

The invention belongs to a liquefied air energy-storage and power-generation system, more particularly to a liquefied air secondary energy-collection and energy-storage power-generation device which takes a plurality of energy sources as motive power and air liquefying storage as a basis, and can carry out secondary energy collection. The liquefied air secondary energy-collection and energy-storage power-generation device comprises an air compressing and liquefying device connected with power input and a steamer power-generation device matched with power output; the output of the air compressing and liquefying device is connected with a liquefied air storage device, the liquefied air storage device outputs a stable air source with the auxiliary function of a secondary energy-collection liquefying device, and the air source provides the motive power for the steamer power-generation device. The invention solves the defect that the working state of the liquefied air is not stable in the working process of the steamer power-generation device under the push of vaporization in the prior art, and has the advantages of stable working state, high system additional value, wide application range, no secondary pollution in the whole working process, and the like.

Description

Technical field [0001] The invention belongs to an air liquefied energy storage power generation system, in particular to a liquefied air secondary energy storage power generation device that uses multiple energy sources as power and is based on air liquefaction storage and can perform secondary energy collection. Background technique [0002] Wind energy, solar energy, and tidal energy are currently recognized green renewable energy sources, but they have the disadvantages of low energy density and poor continuous stability in actual use. For example, the current wind power plants must be equipped with hot standby thermal power plants with corresponding installed capacity to avoid the disadvantages of poor stability when they are connected to the grid for power generation. This method obviously increases the consumption of large additional reactive resources. Disadvantages. [0003] To solve this problem, people have been seeking sustainable and stable wind power generation metho...
