1997年7月原电力部召开了热工自动化领导小组第六次扩大会，对电气设计如何与DCS配合提出了具体意见：“实现炉、机、电集中管理，使电厂主控室炉、机、电控制水平协调发展是必要的而且在现有技术和装备条件下是可行的，可以起到省人、省主控制室面积，便于集控值班运行的作用，而且不提高造价。领导小组要求以积极的态度加入电气纳入DCS的工程试点。”按此精神，九江电厂三期2×350MW、信阳电厂一期2×300MW、益阳电厂一期2×300MW工程电气系统均纳入DCS监控。现依据这几个工程中具体实施的过程和要求，就电气系统纳入DCS监控的一些有关问题进行分析和探讨。

Glossary
Process station:
This term is used to describe AC800F controllers (field controllers) and rack-mounted controllers. A process station can be designed to be redundant
configuration and non-redundant configuration.
AC800F :
This term is used to describe the AC800F Field Controller type of process station. A redundant process station consists of 2
AC800F controller.
Rack mounted process station:
This term is used to describe a rack-mounted type of process station. A redundant process station contains 2 rack-mounted CPUs.
This term is used to describe a single, non-redundant process station.
