摘　　要：余热是限制先进绝热压缩空气储能系统效率提高的主要原因之一。为提高压缩空气储能系统的效率,以某100 MW压缩空气储能系统为对象,研究减少和利用系统余热的方案。通过软件模拟计算,分析提高膨胀机进气温度对系统的影响,以及耦合有机朗肯循环系统发电对系统发电效率的提升。结果表明,在现有系统的基础上,膨胀机进气温度每提高5℃,发电量约提升1.25%,但存在诸多问题;而耦合有机朗肯循环系统,可以充分利用系统余热,提高系统发电效率,净发电功率最高增加686.33 kW。Residual heat is one of the main reasons limiting the efficiency improvement of advanced adiabatic compressed air energy storage system.In order to improve the efficiency of compressed air energy storage system,a 100 MW compressed air energy storage system was taken as an example to study a scheme for reducing and utilizing system residual heat.Through software simulation calculations,the impact of increasing the intake temperature of the expander on the system is analyzed,as well as the improvement of the power generation efficiency of the coupled organic Rankine cycle system.The results show that,on the basis of the existing system,every 5℃increase in the intake air temperature of the expander will increase the power generation percentage by about 1.25%,but there are many problems;The coupled organic Rankine cycle system can fully utilize the system's residual heat and improve the system's power generation efficiency,with a maximum increase in net power generation power of 686.33 kW.
