火电厂DCS接地系统的分析与设计

Analysis and Design of Grounding System for DCS of the Power Plant

DCS接地系统是保证电厂DCS安全可靠运行不可缺少的条件,而且也是避免人身伤害或设备损坏的重要手段。为了保证DCS的监测控制精度和安全、可靠运行,必须对DCS接地进行认真设计。本文分析了DCS系统的接地类型和要求,给出了EDPF-NT PLUS系统接地设计方案及要求。

The grounding system of DCS is necessary to assure the safe and reliable operation of DCS. It is also important means to avoid the hurt of bodies and the damage of instruments. It is necessary to carefully design the grounding system of DCS to guarantee the accuracy of monitoring and control and to guarantee the safe and reliable of operation. This paper analyzed the DCS grounding purpose and requirements, given the grounding design and requirements of EDPF-NT PLUS systems.
