OPC技术在芭蕉河梯级电站集控改造中的应用

Application of OPC Technology in the Renovation of the Centralized Control System in Bajiaohe Cascade Hydropower Stations

在芭蕉河梯级电站集控改造项目中,分析原有芭蕉河梯级电站集控中心的上位机系统及上位机与下位机的通讯方式,采用OPC技术快速有效的实现了新监控系统与原有现地控制单元的数据通讯,减少对原有现地控制单元的二次开发,快速而有效的完成了芭蕉河梯级电站集控系统的改造。

The application of OPC(OLE for process control)technology in the renovation work of the centralized control system in Bajiaohe cascade hydropower stations is introduced.Considering the original communication mode between the host computer,host system and the slave computers,OPC technology is adopted to realize the data communication between the new monitoring system and the original local control units(LCU).With the new technology,the need for secondary development of the LCUs is reduced.The renovation work of the centralized control system is completed quickly and effectively.
