Résumé

In this paper, the performances of two adiabatic compressed air energy storage systems were determined. In system 1#, compressed air was reduced directly from 6.40?MPa to 2.50?MPa. In system 2#, compressed air was first reduced to 5.00?MPa and was later adjusted to 2.50?MPa by an ejector under an ejecting coefficient of 0.45. The mass flow of turbine 1# increased by 45%, and its power output capacity increased from 3.80?MW to 5.51?MW. The energy conversion efficiency of system 2# increased to 65.36% from 61.95% for system 1#. The application of the ejector improved the efficiency by 3.41%.
