摘要(Abstract)：

为了确保绝热-等温压缩空气储能系统连续稳定运行，提出了一种耦合缓冲罐的绝热-等温压缩空气储能方法，建立了耦合缓冲罐系统的动态热力学模型，并搭建实验平台对模型进行了验证，揭示了缓冲罐内空气温度及压力的动态演化机理，探究了缓冲罐设计参数对系统性能的影响规律。研究结果表明：耦合缓冲罐的绝热-等温压缩空气储能系统表现出较好的等温性能，循环过程中空气温度最大温差为30 K；耦合缓冲罐后，储能系统压缩机组的绝热效率提高8百分点；敏感性分析表明，储能功率的变化对储气室内空气热力学参数影响较小，缓冲罐体积随系统储能功率的增大而减小；储能规模的变化对储气室内空气热力学参数影响较小，储气室内空气温度变化呈周期性波动；为保持系统连续稳定运行，增大系统储能规模，缓冲罐体积会随之增加。研究为绝热-等温压缩空气储能系统连续、稳定和高效运行提供了新的方案。
