摘要
简要介绍了水电厂计算机监控系统现地控制单元(LCU)的结构,详细介绍了水电厂计算机监控中2种LCU监控模式——"一体化工控机+可编程逻辑控制器(PLC)"模式和"触摸屏+PLC+通信管理装置"模式的功能、特点及其应用,并着重比较了2种监控模式的不同点及发展趋势。
This paper briefly introduces LCU configurations of the automation system of hydropower plants, particularly the functions and characteristics of “IPC ＋ PLC” mode and “touch screen ＋ PLC ＋ CMU” mode of LCU configuration and their application to automation system of hydropower plants. The difference between and development trend of the two modes are also compared.
