摘要
为探究灌溉供水管网中存在的漏损过高以及局部压力过大的问题,提出了一种基于FCM-GA的供水管网减压阀布设优化方法,该方法借助MATLAB、EPANET、MATLAB-EPANET-Toolkit以及PlatEMO平台等工具,对西班牙的BIN管网进行分区布置减压阀并优化阀后压力,以不同分区方案的成本与降漏效果为控制指标,筛选出最优方案。结果显示:最优方案(分5个区)将整个管网的漏损率降低至7.45%,相较初始管网降低了20.04%,降低的漏损费用可达114€/d,在减压阀服务年限内可收回成本并达到盈利,并实现对整个管网系统的压力管理,提高了管网的稳定性和可靠性,有利于减少管网事故发生。因此,基于FCM-GA的灌溉供水管网减压阀布设优化是一种安全、低成本和高效益的降漏与控压方法,在有效降低灌溉用水费用的同时,可更好地实现节水灌溉。
In order to solve the problems of high background leakage and excessive local pressure in irrigation water supply network,this study proposed an optimization method of pressure reducing valve layout of water supply network based on FMM-GA.The methodology utilizes MATLAB,EPANET,MATLAB-EPANET-Toolkit and PlatEMO platform.The pressure reducing valve was arranged in different zones for BIN in Spain,the pressure behind the valve was optimized.The cost and leakage reduction effect of different zoning schemes were taken as the control index to select the optimal scheme.The results show that:The optimal scheme(divided into 5 zones)reduces the leakage rate of the entire pipe network to 7.45%,which is 20.04%lower than the initial network.It also reduces the leakage cost up to 114€/d,allowing for cost recovery and achieving profitability within the service life of the pressure reducing valve.Additionally,the optimal scheme enables the pressure management of the entire network system,improving the stability and reliability of the pipe network.It is beneficial to reduce network accidents.Therefore,the pressure reducing valve layout optimization of irrigation water supply network based on FCM-GA is a safe,low cost and high efficiency method for leakage reduction and pressure control.It can effectively reduce irrigation water cost and better realize water-saving irrigation.
