Title:
EXPANSION POWER GENERATION SYSTEM FOR COMPRESSED AIR ENERGY STORAGE POWER STATION
Document Type and Number:
WIPO Patent Application WO/2022/088885
Kind Code:
A1
Abstract:
An expansion power generation system for a compressed air energy storage power station, which system comprises a plurality of inter-stage reheating-type air expansion generator sets and a heat storage medium sub-system, wherein each inter-stage reheating-type air expansion generator set comprises air expanders (1, 2, 3, 4) and a set of reheating air storage assemblies connected to the air expanders (1, 2, 3, 4); the air expanders (1, 2, 3, 4) are controllably connected in series, and the set of reheating air storage assemblies are connected in parallel; each reheating air storage assembly comprises inter-stage reheaters (10, 11, 12, 13) and air storage chambers (14, 15, 16, 17) that are successively connected to the corresponding air expanders; and the air storage chambers (14, 15, 16, 17) are respectively connected to air compressors (37, 38, 39, 40) in a compressed air energy storage power station, which is in an energy storage phase, on a one-to-one basis, and the inter-stage reheaters (10, 11, 12, 13) are respectively connected to the heat storage medium sub-system. In practical application, the system can improve the operation stability and the expansion power generation efficiency, and the operation safety of related devices during an expansion power generation process for a compressed air energy storage power station.
