[Abstract]:In order to calculate more accurately the performance parameters of the advanced adiabatic compressed air energy storage system and to investigate the change of temperature and pressure in the gas storage chamber during the cycle, based on the first law of thermodynamics and the ideal gas equation,A more practical constant wall temperature gas storage model is proposed and the thermodynamic model of the whole energy storage system is constructed.Based on this model, the performance of the system is calculated under the given air compressor and turbine power, and the effect of the parameters such as the ratio of storage pressure to air pressure and the interval time between storage and release energy on the system performance is analyzed.The change of temperature and pressure of gas storage chamber with time is revealed intuitively.The results show that the cycle efficiency of the system can be improved by increasing the ratio of storage to air pressure and decreasing the difference of the ratio of storage air pressure to equal amplitude, but only by increasing the ratio of maximum storage pressure to air pressure, and the compression work increases with the increase of convection heat transfer coefficient.When the heat transfer coefficient of convection is small, the cycle stability of gas storage parameters should be taken into account when the heat transfer coefficient of convection is small.
