摘　　要：以水电厂电气自动化机组控制为例,提出基于LCU的水电厂电气自动化监控系统。以现地控制单元LCC和可编程PLC为核心,在系统工作站与自动化机组之间搭建以太网,构建自动发电控制(AGC)监控系统平台,通过分析计算电气自动化机组运行数据,及时发现故障信号,采取有效的冗余控制,以保证水电厂机组的稳定运行。This paper takes the control of electrical automation units in hydropower plants as an example,a monitoring system for electrical automation in hydropower plants based on LCU is proposed.Based on the local control unit LCC and programmable PLC as the core,Ethernet is built between the system workstation and the automation unit to construct an automatic generation control(AGC)monitoring system platform.By analyzing and calculating the operation data of the electrical automation unit,fault signals are detected in a timely manner,and effective redundant control is adopted to ensure the stable operation of the hydropower plant unit.
