Research on Automatic Control of Pump Station Joint Dispatching—Diversion Project in the East of Yuxi City

泵站自动化控制系统适用于城市供水系统中加压泵站的远程监控及管理,对城市输水管正常作业具有重要作用。本文针对泵站群自动化控制系统进行研究,分析了泵站群自动化控制系统存在系统通信难度大、泵站级间联控与集控调度效率低、实时性差等问题,以云南省玉溪东片区饮水工程为例,通过可编程逻辑控制、泵站实时监控设计等分布式方法设计并实现了泵站联合调度自动化控制系统。首先分析了云南省玉溪东片区饮水工程泵站控制存在的实际问题,说明由于地形地质条件复杂,采用常规的控制无法满足泵站控制运行的要求;再次,针对已有泵站输水控制系统效率低等问题,对玉溪东片区饮水工程可编程逻辑控制、泵站实时监控、系统通讯、泵站级间联控与集控调度自动化等进行设计,实现了泵站联合调度自动化控制;最后,通过玉溪东片区饮水工程泵站联合调度自动化控制系统的实施和运行,证明了本文设计并实施的方案能很好地适用于玉溪东片区饮水工程。此外,通过泵与泵站群自动化控制系统能很好完成泵站之间的运行管理,减少了工作量,减少了设备配置,提高了稳定性、时效性和管理水平,有利于信息的资源共享,同时更加有利于泵站群安全运行,对不同地理位置的泵站联合调度控制系统具有借鉴意义。

The automatic control system of pumping station is suitable for remote monitoring and management of pressurized pumping station in urban water supply system,and plays an important role in normal operation of urban water pipeline.In this paper,the automation control system of pumping station group is studied.The problems of the automation control system of pumping station group are analyzed,such as the difficulty of system communication,the inefficiency of joint control and centralized control dispatching between pumping stations,and the poor real-time performance.Taking the drinking water project in Yuxi East Area of Yunnan Province as an example,an automatic control system for joint dispatching of pumping stations is designed and implemented by using distributed method.Firstly,the practical problems in the control of drinking water pumping stations in Yuxi East Area of Yunnan Province are analyzed.It is shown that the conventional control cannot meet the requirements of the control operation of pumping stations because of the complex topographic and geological conditions.Secondly,in view of the inefficiency of the existing pumping station water conveyance control system,a distributed computer monitoring system is designed and implemented for joint dispatch of pumping stations.Finally,through the implementation and operation of the joint dispatching automation control system of the pumping station in the eastern part of Yuxi,it is proved that the scheme designed and implemented in this paper can be well applied to the drinking water project in the eastern part of Yuxi.In addition,through the automatic control system of pumps and pumping stations,the operation management between pumping stations can be well completed,the workload can be reduced,the equipment configuration can be reduced,the management level can be improved,and the information resources can be shared.At the same time,it is more conducive to the safe operation of the pumping station group,and has reference significance for the joint dispatching control system of pumping stations in different positions.
