Application And Design Of Technology Of Fieldbus In Control System Of Electric Power Plant

The paper studies the application of fieldbus in process control of theelectric power plant based on the system of DCS. The paper first analyzes the current situation of application of fieldbus, andintroduces technology of fieldbus, analyzes tendency of fieldbus's development.Summarizes the advantage and superiority of fieldbus relative to the system ofDCS. Finally this control method is applied to actual DCS control system. adetail design scheme is put forward in the control system of the electric powerplant. technology of fieldbus,such as Profibus-DP, Modbus CC-Link Ethernetand so on,are adopted in the design scheme. And design the communicationamong control systems with DCS system.improve the function of DCS systemand improve stability and reliability of system, amplify the function of numeraland network, reduce the cost of systenn and improve the automation level. At last,the pater forecast the application of FCS in the control system of theelectric power plant in the future...
