摘　　要：为提高压缩空气储能系统性能,提出基于太阳能辅热的先进绝热压缩空气储能系统概念,分析系统各项主要设备的热力性能,然后对各设备进行热力学建模。对比分析耦合系统与传统AA-CAES系统的优缺点;研究耦合系统中太阳能辅热设备的布置方式对系统性能的影响。结果表明:相比于传统AA-CAES系统,AA-CAES+CSP系统的储能效率达到69.6%,提升了9%,耦合储能效率也提升了近2%;太阳能辅热系统与蓄热系统布置先后方式会影响系统的性能,初次运行时太阳能辅热系统在后布置方式系统效率较高,而系统稳定运行后,太阳能辅热系统在前布置方式的储能效率和耦合储能效率均较高。In order to improve the performance of compressed air energy storage system,this paper proposes the concept of advanced adiabatic compressed air energy storage(AA-CAES)system based on solar auxiliary heating,analyzes the thermodynamic performance of main equipments of system,and establishes the thermodynamic model for each equipment.Also,the advantages and disadvantages of the coupled system and the traditional AA-CAES system are compared,and the influence of the layout of solar heating equipment on system performance is studied.The results show that compared with the traditional AA-CAES system,energy storage efficiency of AA-CAES+CSP system reaches 69.6%and rises 9%.And coupled energy storage efficiency also increases nearly 2%.The layout of solar heating subsystem and regenerative subsystem may affect system performance.For the first operation,system efficiency is higher when solar heating subsystem is arranged in post.After system stably operation,both energy storage efficiency and coupled energy storage efficiency are higher when solar heating subsystem is arranged in fore.
