分散控制系统供电和接地系统的设计与应用

Design and application of DCS power supply and grounding system

目前绝大多数电厂都将分散控制系统作为机组的控制核心。分散控制系统的长期稳定、准确运行,能提高机组的运行效率、安全性,减少非正常停机的次数,是保证发电机组安全可靠经济运行的重要前提。文章论述了分散控制系统供电与接地的设计和应用,并提出了几点需要注意的问题。

Most of the generating units are controlled by the DCS.The stable and accurate DCS can enhance the operating efficiency of the generating units,make the generating units safer,and avoid the unusual shutdown of the generating units.The author systematically introduces the plan and the application about the power supply system and the grounding system of the distributed control system.And points out the affair need to pay attention during the process.
