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 storage unit (5), at least one compressor (1, 3) which is fluidically connected to the compressed air storage unit (5) via at least one compressor line (14) in order to charge the compressed air storage unit (5) with air, and an expander (11) which is fluidically connected to the compressed air storage unit (5) via at least one expander line (15) for discharging the compressed air storage unit (5), wherein the heat produced during compression of the air in the at least one compressor (1, 3) can be conveyed, via at least one heating line (8) of the compressed air storage power plant (20), into the expander (11) to heat the expander (11). The invention also relates to a method for operating such a compressed air storage power plant (20).
