一、前言节省能源是现代城市不可忽视的一个方面。优化调度是城市供水系统节省能源、降低成本的重要途径。测压点的布置是供水系统优化调度的一个重要环节;通过对管网中有限的节点的水压测量来反映整个系统的全貌。为计算机在线优化调度提供必要的可靠信息. 所谓测压点的最优布置是指确定测压点的数目和位置,以满足优化调度所用的模型的精度要求,同时又尽量减少经费开支。很明显,精度要求和径费开支是相互矛盾的。目前,国内对此研究甚少.通常,由自来水公
I. Preface Saving energy is an aspect that can not be ignored in modern cities. Optimal scheduling is an important way for urban water supply system to save energy and reduce costs. The arrangement of pressure measurement points is an important part of water supply system optimization scheduling. The whole system is reflected by the hydraulic pressure measurement of limited nodes in the pipe network. Which can provide necessary and reliable information for computer online optimization scheduling.The optimal arrangement of pressure measurement points is to determine the number and location of pressure measurement points in order to meet the precision requirements of the model used in the optimal scheduling and to minimize the expenditure at the same time. Obviously, accuracy requirements and path expenses are contradictory. At present, there is little research on this topic in China, usually by water utility
