摘　　要：为了解决乡镇农村等偏远地区供水管网分布不均匀,地域落差大、水压不稳定、能耗高等用水难的问题,以节能型乡镇供水系统以乡镇供水管网为研究对象。通过对管网用水流量以及最不利供水点的水压监控,结合智能控制技术,利用管网用水量变化动态调整水压,对管网供水参数进行采集和模糊控制,控制单元对供水系统进行优化,通过对多台水泵电机变频调速,使供水管网的流量和总扬程达到最佳工况点。结果达到管网出水口的压力随着供水量的改变而改变的要求,实现变压变量供水。最终达到节约扬程,稳定水压、降低能耗的目的。The energy-saving township water supply system takes the township water supply pipe network as the research object, and aims to solve the problems of water distribution problems such as uneven distribution of water supply pipe networks, large regional differences, unstable water pressure, and high energy consumption in remote areas such as towns and villages. The method is to monitor the water flow of the pipe network and the water pressure of the most unfavorable water supply points, combined with intelligent control technology, to dynamically adjust the water pressure using changes in the water consumption of the pipe network, and to collect and fuzzy control the water supply parameters of the pipe network. The control unit controls the water supply system. Optimize and adjust the frequency of multiple pump motors to make the flow and total head of the water supply pipe network reach the optimal operating point. As a result, the pressure of the outlet of the pipe network is changed with the change of the water supply amount, and the variable pressure water supply is realized. Finally, the purpose of saving head, stabilizing water pressure and reducing energy consumption is achieved.
