Performance Analysis of AA-CAES System With Constant Wall-temperature Air Storage Model
摘要
Abstract
To calculate the performance parameters of advanced adiabatic compressed air energy storage (AA-CAES) system more accurately and explore the variations of temperature and pressure in air chamber during steady cycle, the constant wall-temperature storage model which is more practical was proposed and the thermodynamic model of AA-CAES system was built based on the first law of thermodynamics and ideal gas equations. The performance of system was computed at a given input/output power utilizing the model. The cycle efficiency of system was analyzed separately under conditions of different pressure ratio of storage chamber and diverse intervals, and the variations of temperature and pressure of air chamber was revealed during steady cycle. The results show that cycle efficiency of system is improved by enlarging the maximum and minimum pressure ratio with equal amplitude and lowering the pressure ratio difference, while efficiency is reduced by increasing the max pressure ratio individually. With the heat transfer coefficient increasing, the compression work increases and the turning point appears on the curve of efficiency and expansion work. The increase of interval between compression and expansion leads to lower efficiency. However, the cycle stability of parameters in chamber should be taken into consideration for the selection of the interval with smaller heat transfer coefficients.关键词
