Title:
COMPRESSED AIR STORAGE AND POWER GENERATION DEVICE AND COMPRESSED AIR STORAGE AND POWER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/017639
Kind Code:
A1
Abstract:
A compressed air storage and power generation device (1) is provided with motors (3a-3c), compressors (4a-4c), compressed air storage tanks (5a-5c), injection-side valves (6a-6e), expanders (7a-7c), discharge-side valves (8a-8e), generators (9a-9c), an output sensor (10), pressure sensors (11a-11c), and a control device (12). The control device (12) uses a tank (5c) with a relatively large capacity for long-period variable power and uses tanks (5a, 5b) with relatively low capacities for short-period variable power, all such power having been generated using natural energy, and thereby performs control by which both the long-period and short-period variable power are levelled out and power is output according to the power demand. The compressed air storage power generation device (1) levels out both the long-period and short-period variable power and outputs the power according to the power demand.
