| 摘 要： | 对变频调速变压变量供水及数据采集处理系统进行了设计与研究，采用ＣＡＤ技术进行管网平差计算，建立了不同流量段的管网最不利点压力控制数学模型，并在可编程序控制器和变频调速器及水泵并联运行环境下，实现了供水运行的变压变量调节，使供水系统处于最佳工况，解决了目前正在推广应用的恒压变量供水方式所存在的水电浪费问题，达到了供水运行理想的节能目的。同时本文还采用通讯连接手段，在下位机与上位机以及可编程序控制器之间实现了实时通讯和运动控制，达到了数据自动采集、存贮、处理和动态监视之目的，提高了水厂的现代化管理水平。

| Abstract: | Investigation and design on frequency control of motor speeds to variable-press variate in water supply system and data collection system is carried out.The mathematical model about the most unfavourable point press control of diffirent flow rate section is created after taken the CAD to compute adjusted values.Furthermore,the variable-press varite regulation of water supply system in motion come into being in The condition of the programming program controller,frequency controller of motor speeds and compressed water pump installing in parallel.it is proved to be better than the constant-press variate regulation which results in a waste of water and electric energy.The real-time control and distant dynamic control among the upper machines,the lower ones,and controller is realized for automatic collections,storages and analyses of date so as to develop the modernization of management of water works |
