| Abstract: | The design flow,system architecture and its software structure of the coal feeding
system in power plant is introduced in this paper.The systsm,by adopting the international
advanced techniques such as three-stage DCS,timely managemen system and the graphic
monitoring,can realize the automatic control and monitoring of coal-feeding in power plant.And by
using stage programming,it also can decrease the system scanning time and responsing time. |
