System and method of using a compressed air storage system with a gas turbine

A power generation system (200) includes a first compressor (202), a second compressor (206), a combustor (232) configured to receive compressed air from the second compressor (206) to produce an exhaust stream, a first turbine (238), and a power turbine (244). The first turbine (238) is configured...

Beschreibung
Zusammenfassung:	A power generation system (200) includes a first compressor (202), a second compressor (206), a combustor (232) configured to receive compressed air from the second compressor (206) to produce an exhaust stream, a first turbine (238), and a power turbine (244). The first turbine (238) is configured to receive the exhaust stream, generate a rotational power from the exhaust stream, output the rotational power to a second compressor (206), and output the exhaust stream. The system (200) includes a coupling device (212) configured to couple and decouple the first compressor (202) to/from a second turbine (242), an electrical generator (210) coupled to an output of the power turbine (244) and configured to output electrical power, and a controller (256) configured to cause the coupling device (212) to mechanically decouple the second turbine (242) from the first compressor (202), and cause the coupling device (212) to direct compressed air from an air storage cavern (224) to an inlet (208) of the second compressor (206).
