Compressed air storage power plant and method for operating a compressed air storage power plant

摘要

The present invention relates to a compressed air storage power plant (20), comprising a compressed air reservoir (5), at least one compressor (1, 3) which communicates with the compressed air reservoir (5) for supplying the compressed air reservoir (5) with air via at least one compressor line (14) and an expander (11) which is connected in a fluid-communicating manner to the compressed-air accumulator (5) via at least one expander line (15) for relaxing the compressed-air accumulator (5), wherein the compressed air is compressed in the at least one compressor (1, 3) ) heat can be conducted via at least one heating line (8) of the compressed air storage power plant (20) for heating the expander (11) in the expander (11). Furthermore, the invention relates to a method for operating such a compressed air storage power plant (20).
