电厂输煤自动控制系统设计

Design of Automatic Control System of Coal Transport in Power Plants

设计基于PLC控制的发电厂输煤自动控制系统,同时利用上位机组态软件进行实时监控。其中控制主站系统采用西门子S7-300系列PLC实现了对输煤系统的运行控制,上位机监控系统采用组态王软件实现了对输煤系统运行状况的监控和记录。本设计使输煤系统具有更加安全、自动化以及控制的高可靠性等优点。

The paper puts forward a detailed design plan of both controlling system of primary station and upper-computer monitoring system in automatic control system of coal transport based on datum coal and electricity group. The controlling system of primary station adopts S7-300 series PLC produced by SIEMENS to achieve controlling operation of coal transport and upper-computer monitoring system uses KingView to monitor and record operation conditions.The system is safe reliable and stable and it improves automation level in power plants.
