摘要

为了提高压缩空气储能(CAES)系统的效率，提出了新型变压比压缩空气储能系统。该系统基于定容储气装置及传统定压比压缩方式的特性，通过阀门调节来改变储能过程中压缩级组的串并联运行方式实现。通过分析不同压缩级数下可行的变压比运行方式，建立变压比压缩空气储能系统的仿真模型，从仿真得出的变压比储能系统的储能时间、压缩功耗和系统的充放电效率等方面，与传统的定压比压缩空气储能系统进行比较。结果表明，变压比压缩空气储能系统不仅减少了储能过程中压缩机组的功耗、缩短了储能时间，而且提高了整个系统的充放电效率。

Abstract

In order to improve the efficiency of the compressed air energy storage(CAES)system

a novel CAES system with variable pressure ratio is proposed. The system is realized by adjusting valves to change the series and parallel operation modes of compressor stages

which is based on the characteristics of constant volume gas storage devices and traditional compression with constant pressure ratio. The time for energy storage

the power consumption of compressor and the charging and discharging efficiency of system are calculated by analyzing the feasible operation modes of variable pressure ratio under different compression stages and establishing the simulation models of the variable pressure ratio CAES systems

which are compared with the parameters of conventional CAES system with constant pressure ratio. The results show that the new system can not only reduce the power consumption of the compressor group in the energy storage process and shorten the energy storage time

but also improve the charging and discharging efficiency of system compared with the conventional CAES system with constant pressure ratio.
