摘要

针对某盐穴压缩空气储能（CAES）项目

利用Python编写储能和释能全周期过程的系统计算程序

研究最高储气压强、膨胀节流压强、压缩机排温及再热级数对盐穴压缩空气储能系统特性的影响。结果发现：对于同一再热级数的压储系统

存在一个最优的最高储气压强和膨胀节流压强

此时压缩总耗功最小

系统转换效率最高;对于同一再热级数的压储系统

系统转换效率随着定压压缩机排温增大而增大

但变化趋势变缓;定压压缩机排温为400 ℃的一级再热压储系统具有最小压缩机耗功、最低气耗率和最高转换效率

其最高转换效率为71.43%

相对于三级再热型式提高了6.48%。

Abstract

A system calculation program for the full cycle process of energy storage and release was written by Python for a salt cavern compressed air energy storage （CAES） project. The effects of the highest storage gas pressure

expansion throttle pressure

compressor discharge temperature

and reheat stages on the characteristics of the salt cavern CAES were studied. The results show that there is an optimal highest storage gas pressure and expansion throttle pressure for CAES with the same reheat stage. At this time

the total compression power consumption is the smallest and the conversion efficiency is highest. The system conversion efficiency increases with the increase of the compressor discharge temperature for CAES with the same reheat stage

but the change trend slows down. The one-stage reheat CAES with compressor discharge temperature of 400 ℃ has the smallest compressor work consumption

the lowest gas consumption rate

and the highest conversion efficiency. The highest conversion efficiency is 71.43%

which is 6.48% higher than that of the three-stage reheat type.
