摘要:

当前压缩空气储能已进入商业化发展初期,以绝热式压缩空气储能系统(A-CAES)为主要技术路线,而在工程实践中仍未形成一套系统性、通用性的A-CAES设计体系。本文通过模块化方法编写热平衡设计与动态性能计算耦合的A-CAES设计程序,以某300MW A-CAES项目作为研究对象,对蓄热温度与储气室压力波动范围关键设计参数展开分析。结果表明:A-CAES蓄热温度随膨胀机级数增加而减小,当级数越大时蓄热温度下降幅度减小。2级膨胀机对应高温方案,3级及以上膨胀机级数对应中温方案,不同膨胀机级数对应蓄热温度范围并不相交;当储气室压力波动范围增大时,系统效率下降,储能密度增加。当储气室压力波动范围作为设计优化参数时,需要综合考虑储能密度与系统效率影响。

Abstract:

At present, compressed air energy storage has entered the initial stage of commercial development, with adiabatic compressed air energy storage systems (A-CAES) as the main technical route. However, in engineering practice, a systematic and universal A-CAES design system has not yet been formed. This paper uses a modular approach to develop a design program that couples thermal balance design and dynamic performance calculation for A-CAES. Taking a 300MW A-CAES project as the research object, the key design parameters of heat storage temperature and pressure fluctuation range of the gas storage chamber are analyzed. The results show that the heat storage temperature of A-CAES decreases with the increase of the number of expansion stages, and the decrease in heat storage temperature becomes smaller when the number of stages is larger. The two-stage expansion machine corresponds to the high-temperature scheme, and the three-stage and above expansion machines correspond to the medium-temperature scheme. The heat storage temperature ranges corresponding to different expansion stages do not overlap. When the pressure fluctuation range of the gas storage chamber increases, the system efficiency decreases and the energy storage density increases. When the pressure fluctuation range of the gas storage chamber is used as a design optimization parameter, the influence of energy storage density and system efficiency should be comprehensively considered.

Key words: Adiabatic compressed air energy storage system, thermodynamic system, engineering application
