Design Study of a 300 MW Medium-Temperature Adiabatic Compressed Air Energy Storage

近年来,绝热压缩空气储能技术引起了广泛关注。为了对绝热压缩空气储能进行设计,需要对其技术方案及技术参数进行研究。首先提出压缩空气储能系统的计算模型,并对模型进行对比验证。然后,以岩石硐库储气库的300 MW中温绝热压缩空气储能系统为例,比选得到透平机入口压力17 MPa、压力波动范围6 MPa为最优方案;并根据运行参数的计算,得到300 MW中温绝热压缩空气储能的设计方案。提出的建模过程及分析方法可以用于绝热压缩空气储能项目的设计。

In recent years,adiabatic compressed air energy storage technology has attracted extensive attention.In order to design the adiabatic compressed air energy storage,it is necessary to study its technical scheme and parameters.Firstly,the calculation model of the compressed air energy storage system is proposed and verified.Then,taking a 300 MW medium temperature compressed air energy storage system with a rock cavern as the gas storage chamber as a case study,the optimal plan is selected with a turbine inlet pressure of 17 MPa and a pressure variation range of 6 MPa.Based on the calculation of operating parameters,the design scheme of a 300 MW medium temperature adiabatic compressed air energy storage thermal system is obtained.The modeling process and analysis method proposed can be used for the design of the adiabatic compressed air energy storage projects.
