分区计量体系下的供水管网建模节点用水量分配

Node-Flow Distribution in Modeling of Water Supply Pipelines Network under the System of District Metering Area

节点流量分配对于供水管网建模过程至关重要,随着国内各城市和地区管网地理信息系统和数据采集系统的建立和完善,管网分区计量管理也得到了越来越广泛的应用。在管网分区计量体系下,供水管网建模节点水量可以被更加准确地计算并分配至管网中相应节点。文中首先对于节点流量基本分配方法做了简单的介绍,然后对于分区计量体系下供水管网建模节点流量分配流程做了详细的阐述,最后通过上海市奉贤区供水管网建模工程案例说明了该分配方法的合理性和有效性。

Node-flow distribution is of great importance to the modeling process of water supply pipelines network.With the establishment and improvement of geographic information system(GIS)and supervisory control and data acquisition system(SCADA),district metering technology of water network has been more and more widely used.Node-flow can be more accurately calculated and distributed to the corresponding nodes in the network under the system of district metering area.In this paper,basic methods of node flow distribution were briefly introduced,and then node-flow distribution in modeling of water supply pipelines network under the system of district metering area was described in detail.Finally,the rationality and effectiveness of this distribution method were illustrated through a real engineering case in Fengxian District,Shanghai City.
