Abstract
The present invention relates to a gas-storage power plant, comprisinga gas reservoir (8) in which a gas can be stored under pressure,a turbogroup (2) which has at least one turbine (3, 5),a gas-supply line (9) which leads from the gas reservoir (8) to the turbogroup (2), anda valve arrangement (12) which is arranged in the gas-supply line (9) and throttles a storage pressure (PS) applied on the inlet side to a working pressure (PA) by closed-loop and/or open-loop control.In order to improve the reliability of the valve arrangement (12), it has at least two control valves (13, 14) arranged in series. A leading first control valve (13) throttles the storage pressure (PS) applied on the inlet side to an intermediate pressure (PZ) by closed-loop or open-loop control. A subsequent second control valve (14) throttles the pressure (PZ) applied on the inlet side to the working pressure (PA) by closed-loop control.
