To evaluate the importance of the startup process of the compressed air energy system (CAES), a mathematical model of the entire system was established based on a 300 MW CAES power plant. A series of analyses were conducted to evaluate the changes in the main parameters during the startup and the corresponding dynamic responses were obtained. These analyses include the antisurge operation of the compressors, 1drive4 variable frequency startup of the compressor train, the programmed startup of the turbine train, and the power regulation process under the airdistribution scheme. The results indicate that the optimization of startup process can shorten the start time of the compressor and turbine trains and improve the system efficiency. In addition, the qualitative data during many important operation process was determined. The study provides valuable date and theoretical basis for the safe and efficient operation of the CAES unit.
