摘要
研究了CAES释能过程各部件的数学模型及控制逻辑,基于MATLAB/Simulink平台建立了CAES释能过程的动态仿真模型。利用该模型对启动过程、准同期并网过程、变工况过程进行仿真。在此基础上,分析了多种工况下运行参数及效率的变化规律。结果表明:在200~300 kW功率范围内,膨胀机等熵效率变化范围为75%~88%,?效率变化范围区间为73%~84%。
The mathematical model and control logic of energy release process in compressed air energy storage(CAES)were studied.The dynamic simulation model of CAES energy release process was established using MATLAB/Simulink platform for the simulation of start-up process,quasi-synchronized grid connection process and off-design condition process.The variation of operating parameters and efficiency under multi conditions were analyzed.Results show that within the power range of 200-300 kW,the expander efficiency is in the range of 75%-88%,and the exergy efficiency is in the range of 73%-84%.
