在某制氧厂增压机改造工程中，使用西门子自动控制系统来实现原来使用的美国的QUAD控制器的功能，并与QUAD系统互为冗余互不干扰。描述了该自动控制系统的控制方案和控制功能，由于使用了西门子自动控制系统，使得该系统具有远程和本地两地控制和监控、经济可靠、维修方便、智能保护等优点。%In the supercharger revamping project at an oxygen plant, Siemens automatic control system was used to achieve the function previously performed by Quad controller of USA and form bilateral redundancy and non-interference with the Quad system. This paper introduces the control program and control function of the automatic control system. After adopting the Siemens automatic control technique, the system can be controlled and monitored both remotely and locally with the advantages of low cost, high reliability, easier maintenance and intelligent protection.
