摘　　要：为了正确掌握大容量压缩空气储能电站压缩和膨胀系统启动关键过程的特性,文章建立了300 MW级压缩空气储能电站的全工艺系统数学模型,定量分析了压缩和膨胀系统启动过程的关键参数变化规律和动态响应特性,包括压缩机的防喘操作、压缩机组的变频1拖4启动、透平机组的全自动程启、透平的配气调节特性等。研究表明:合理的防喘策略可在保证机组安全的前提下提高启动过程中系统的效率;系统启动过程的精确评估可优化启动流程、缩短启机时间、提高系统效率,为机组的安全、高效启动提供数据参考和理论依据。To evaluate the importance of the start-up 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 start-up and the corresponding dynamic responses were obtained. These analyses include the anti-surge operation of the compressors, 1-drive-4 variable frequency start-up of the compressor train, the programmed start-up of the turbine train, and the power regulation process under the air-distribution scheme. The results indicate that the optimization of start-up 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.
