建立基于压力驱动节点流量原理的城市供水管网水力模型,通过水力模拟对城市供水管网实现三级分区。构建供水管网系统三级分区漏失检测与控制体系,在一级调度分区建立泵组优化调度控制漏失模型,实现水厂间水量的最优调度;在二级分区建立减压阀优化调控模型,实现区域压力最优控制;在三级分区建立漏失检测区域定位模型,实现漏失区域快速定位。城市供水管网三级分区漏失控制技术已应用于CP市管网,使分区工作规范化进行,取得了良好的效果。
The hydraulic model of urban water supply network based on the principle of pressure-driven node flow is established, and the third-level partition of urban water supply network is realized by hydraulic simulation. Build a three-level partition loss detection and control system for water supply pipe network system, set up pump group optimal dispatch control leakage model in the first-level dispatch zone to realize the optimal dispatch of water volume between water plants, and establish the optimal regulation model of the second- To achieve the optimal control of regional pressure; to establish a leakage detection area positioning model in the three-level sub-area so as to realize the rapid positioning of the lost area. Urban water supply network level three district leakage control technology has been applied to CP city pipe network, so that the work of the district standardized, and achieved good results.
