Abstract
A compressed air energy storage power station comprises a first shafting () and a second shafting (). A gas turbo group (), an electrical machine () and a compressor () are arranged on the first shafting (). Switchable clutch elements () are arranged between the electrical machine and the gas turbo group or the compressor. The clutch elements allow a connection to be selectively made between the electrical machine and the gas turbo group () or the compressor (). An expansion machine () for the power generating expansion of a pressurized storage fluid, an electrical machine () and a compressor () are arranged on the second shafting (). Switchable clutch elements () are arranged between the electrical machine and the expansion machine or the compressor and allow the electrical machine to be optionally connected to the expansion machine and to the compressor. The electrical machines are operable both as generators and as electric motors.
