摘　　要：火电厂补给水处理程控系统采用以太网为高速数据通信网,具有分布式通信功能。程控系统分为:一级控制网络采用工业标准,主要保证可编程逻辑控制器(PLC)与上位机的数据交换,二级控制网络主要实现上位机之间、上位机与服务器之间、服务器与管理信息系统(MIS)之间数据交换,使用TCP/IP协议。PLC对锅炉补给水处理系统的设备进行开关和启停控制,信息动态地上传,可在CRT显示。选用Intouch为锅炉补给水处理系统监控软件。阐述了PLC的选用、CRT控制画面(程控/程组/手动/解列4种控制方式及运行、再生、失效、备用4种运行工况)的操作。The monitoring and control system of makeup water treatment in thermal power plant applies Ethernet as high speed data communication network with distributed functions. It has two hierarchical control networks. The first level control network adopts industrial standard to ensure the data exchange between PLCs（Programmable Logic Controllers） and superordinate computers. The second one uses TCP/IP protocol to realize data exchange between superordinate computers,as well as between superordinate computer and server or management information system. PLC controls the on- off or start- stop of devices in boiler makeup water treatment system and sends corresponding information dynamically for CRT （Cathode Ray Tube ） display. Its monitoring and control software is Intouch. The selection of PLC and the operation of CRT menu are presented ,including four control modes （sequential / step / manual/separate ） and four operation conditions （operation / purge / fault / standby）.
