AA-CAES启动过程中膨胀机自动控制对运行稳定性的影响
Impact of expander automatic control on operational stability during AA-CAES startup process
摘要
Abstract
To investigate the operational regulation strategy,complexity,and stability of the expander during the startup process of an advanced adiabatic compressed air energy storage(AA-CAES)system,proportional-integral-derivative(PID)control was implemented on the temperature and pressure parameters at the expander inlet based on the established expander energy release model.The effects of the pressure gain coefficient K and temperature proportional coefficient Kp on the startup characteristics of the expander were systematically analyzed,including the dynamic responses of output power,outlet temperature,and outlet pressure,as well as the stability during the startup process,thereby enhancing the system's anti-interference capability to address sudden failures of key equipment.The results showed that when K=0.5,compared with K=1.5,the output power peak was 4.2%higher,the pressure decline was more gradual,and the curve slope was smaller,exhibiting better response smoothness.When Kp=0.1,the peak expansion ratio was about 0.54%higher than that when Kp=0.5,while the peak isentropic efficiency at different Kp values remained consistent,both reaching 0.88.When K=1.0,the peak outlet temperature was the smallest and the stabilization time was the shortest.When Kp=0.3,the isentropic efficiency could rapidly stabilize.The findings indicate that reasonable regulation of PID parameters can significantly improve the expander startup performance,thereby providing control strategies for solving the problem of unit stability degradation caused by key equipment failures.关键词
