喘振是造成压缩机损坏的重要原因，在此针对某厂70万吨/年烯烃项目，根据丙烯工艺流程，设计了一套压缩机的防喘振控制系统。该控制系统以TRIEW软件为人机界面，利用TRICON独有的防喘振控制软件包，将喘振PID控制、喘振超驰、手动控制算法相结合，通过喘振PID参数的在线优化，有效地实现了压缩机的防喘振控制，现场实际运行结果表明了该系统的稳定性和可靠性，同时，验证了该喘振控制算法的有效性。

Surge is the main reason to cause the compressor damage. For 700000 t/a olefin project,an anti-surge control system for compressors was designed according to a factory propylene technological process. The control system takes TRIVEW software as the man-machine interfase,and combines surge PID,surge override with manual control algorithm by means of TRICON′s own unique anti-surge control software package. The anti-surge control of compressor was achieved after optimization of surge PID parameters. The practical operation result shows the stability and reliability of the system,and verifies the effective-ness of the surge control algorithm.
