几种典型DCS系统调节器原理对比介绍

Inter-comparison of Regulating Principles in Several Typical Types DCS

为保证DCS调节回路组态正确、回路调试一次成功并节省仪表调试时间,通过对目前石化行业常用的各种DCS系统进行认真细致地分析,整理出具有代表性的IA系统、Provox系统以及MACS等3个系统,并对其调节器原理和对现场阀门的控制进行对比介绍,深入剖析了它们的异同点,对自控工程组态人员具有很好的参考意义。

In order to guarantee correct loop configuration in DCS and successful commissioning in once to save valuable time, aiming at practice current petrochemical enterprises, the commonly used types DCS have been analyzed and compared carefully. As representativeness, three types of the DCS, i. e. , IA system,Provox and MACS are summarized on regulating principle, the field control on valves, as well as their similarities and differences. It is significant for configuration engineers.
