An exergy analysis of a traditional compressed air energy storage system

压缩空气储能技术是具有较大发展前景的大规模储能技术之一,具有广阔的发展前景。使用Aspen Plus软件以传统压缩空气储能系统为例进行流程模拟,运用分析方法对模拟结果进行热力性能分析。分析结果表明,燃烧室的损失是系统各设备损失中最大的。同时还对压缩空气储能系统各个组成部件的运行效率与储能系统的损失之间的关系进行了敏感性分析,分析结果表明,对系统效率影响最大的参数为燃烧室效率,最小的参数为膨胀透平绝热效率。

Compressed air energy storage（CAES） technology is one of the large-scale energy storage technologies with great commercial potential.This paper reports a simulation study on the CAES using the Aspen Plus software package.Exergy analyses are carried on the performance of the CAES and the result indicates the largest exergy loss in the combustion chamber.A sensitivity analysis is performed on the effects of the component efficiencies on the exergy loss of the CAES system.The results show that the efficiency of the combustion chamber has the biggest influence on the system exergy efficiency,while the adiabatic efficiency of expansion turbine has the smallest influence.
