摘　　要：压缩空气储能系统的空气压力参数特性与膨胀透平发电机启动的参数要求相矛盾,使得机组在启动过程中升速和低功率时不易控制。通过对喷气射流装置的热力特性进行分析,设计基于喷气射流装置的改进型压缩空气储能系统,制定启动阶段控制策略,可以将压缩空气的高焓值小流量转化为混合气体的低焓值大流量,能够提高压缩空气储能冲转阶段和低负荷阶段的控制精度,达到膨胀发电机启动时的参数要求,实现压缩空气储能系统参数特性的解耦,而且能够提高系统效率。The air pressure parameter characteristics of the compressed air energy storage system contradict with the parameter requirements of the expansion generator startup,making it difficult to control the unit during startup and low power.By analyzing the thermal characteristics of the jet device,wecoulddesign an improved compressed air energy storage system based on jet devices and develop a control strategy of start-up phase,converting the small flow withhigh enthalpy of compressed air into large flow with low enthalpy of mixed gas,which can improve the control accuracy of the compressed air energy storage cycle and the low load phase,the parameter requirements for starting the expansion generator are decoupled from the parameter characteristics of the compressed air energy storage system,and the system efficiency can be improved.
