景电工程支渠闸门闭环自动化控制系统建设

Automatic Closed Loop Control System of Branch Gate of Jingtaichuan Electric Power Pumping Irrigation Project

为了提升景电提灌工程的运行管理现代化水平,分析了影响支渠闸门闭环自动化控制的闸门、供电及通信、应用软件、自动化设备等因素,在总结工程闸门远程计算机监控技术经验的基础上,开发建设了支渠闸门闭环自动化控制系统。该系统由闸门、闸门启闭执行机构、供电系统、远程测控终端、通信系统、信息采集设备、中心调度系统等组成。系统提高了支渠流量调节的准确性、及时性,以及水量计量的准确性和公正性,减轻了闸门操作人员的劳动强度等。

In order to improve the level of modernization of operation and management of Jingtaichuan Project, the paper analyzed the influence fac- tors of automation closed loop control of branch gate, such as gate, power and communication, application software and automation equipment etc. Based on the summary of remote computer monitoring technology of gate, we developed the automation closed loop control system of the branch gate. The system consists of gate, gate opening and closing actuator, power supply system, remote measuring and controlling terminal, communica- tion system, information collection equipment and central scheduling system etc. The system improves the accuracy, the timeliness of the flow regu- lation in branch, the accuracy and fairness of the water metering, and reduces labor loads.
