给水管网水力模型的建立及应用

Establishment and Application of Drinking Water Network Hydraulic Model System

某市供水管网水力模型以管网地理信息系统、客户营销系统、数据采集与监控系统为基础,整合三大系统的数据,采用计算机模拟的方式来表现供水管网各管段及泵站的流量、压力、流速、流向、水力坡度变化,分析和评价管网布设的合理程度及运行规律,优化管网设计,完善供水调度方案.该模型的建立及应用能够为决策者提供参考依据,使供水企业逐渐告别粗放型的管网运行管理模式,令供水管网处于良性运行状态.

Drinking water network hydraulic model is built based on Geographic Information System （ GIS system）, customer service system and central Supervisory Control and Data Acquisition （SCADA system） ; integrates the basic data of the ＂three system＂ ; by using the computerized simulation represents flow, pressure, velocity, flow direction and hydraulic grade level of the nodes and pipelines of the water supply network. It provides detailed analysis method and evaluation tools in order to analyze network operation situation, optimize network design proposal and water dispatch proposal. It also provides good reference for the decision making, improves network operation mode, and helps the network to be operated in better condition.
