摘　　要：采用变比热模型进行压缩空气储能系统设计点热力计算,进行系统设计参数对储能效率影响的研究。模拟储热型压缩空气储能系统的算例计算结果表明:随着压气机压比的增加,总效率呈非线性增加,且增加速率越来越小。当压气机绝热效率较高时,只需要较低的压比即可实现高的总效率;随着储热罐的保温系数、总压恢复系数的增加,系统总效率呈单调增加;压气机进气温度对总效率的影响非常小;储能系统总效率随着压气机、涡轮机绝热效率的增加呈线性增加,但对涡轮机绝热效率更敏感;储能系统总效率随五个参数的增加都呈单调增加,不呈先增加后降低的抛物线特性,可简化储能系统总体方案设计。With the increase of pressure ratio of compressor,the increase of total efficiency is nonlinear,and the increase rate becomes smaller and smaller.When the adiabatic efficiency of the compressor is high,only a low pressure ratio is required to achieve high overall efficiency;With the increase of the insulation coefficient and total pressure recovery coefficient of the heat storage tank,the total efficiency of the system increases monotonically;the effect of compressor inlet temperature on total efficiency is very small and can be ignored;The total efficiency of the energy storage system increases linearly with the increase of the adiabatic efficiency of the compressor and turbine,but it is more sensitive to the adiabatic efficiency of the turbine;The total efficiency of the energy storage system increases monotonically with the increase of the five parameters.There is no parabolic characteristic that increases first and then decreases,which can simplify the overall scheme design of the energy storage system.
