三重冗余、容错控制器在延迟焦化装置富气离心压缩机防喘振控制中的应用

Application of Triple Modular Redundant Controller in Centrifugal Compressor’s Anti-surge Control in Delayed Coking Unit

通过对富气压缩机的喘振、喘振点及喘振线的分析,制定出防喘振控制方案。详细介绍喘振线的计算方法及TRICONEX系统的组态及操作,从而更好地理解TRICONEX的防喘振控制系统的独特性、完善性及安全性。

By analyzing the surge, the surge point and the surge control line in the centrifugal compressor, the anti-surge control scheme is formulated. The algorithm of surge control line, configuration and operation of TRICONEX system in anti-surge control are introduced.
