摘要
提出基于S7-200的发电厂化学监控系统设计方法。选用WinCC+西门子PLC的组合方案,应用S7-200可编程控制器的功能块,实现发电厂化学部分的分散数据采集及给水、炉水加药控制,提高设备运行效率和可靠性。
This paper presents a design method of the chemical monitoring system for power plant based on S7-200. Combination of host PC software WinCC + Siemens PLC,this method fully applies the S7-200 programmable controller function block,and realizes distributed data acquisition and controls dosing system for feedwater and boiler water in chemical section for power plant,improving operating efficiency and reliability of the equipment.
