摘　　要：针对城市供水系统控制节点多、各引调水工程联动性高、水量调度过程复杂等问题,在WAS模型的基础上增加水库/闸泵—水库/闸泵、水库—闸泵—水厂用户拓扑矩阵算法,构建城市供水调度模型,并以深圳市为例,从水厂、水库、引水工程各角度进行日尺度的全市水量调度计算分析,以历史场景开展模型验证。结果表明,模型进行连续7 d水量调度模拟,各时段水厂总水量计算误差均在0.5%以内;水库时段末存蓄水量误差在4%以内;各工程水量分配偏差在7%以内,满足城市短中期供水水量调度模拟计算精度要求。Aiming at the problems of urban water supply system with many control nodes, high linkage of water diversion projects, and complex water allocation process, the WAS model was modified by adding topology-matrix of reservoir-sluice-pump and reservoir-sluice-pump-water plant, and the scheduling model of urban water supply system was established. Taking Shenzhen City as an example, the daily-scale water scheduling was analyzed considering water plant, reservoir and water diversion project. The model was validated with historical scenarios. The results show that when the model was applied to simulate continuous 7 days water dispatch, the error in calculating the total water quantity of water plants was within 0.5%, the error in reservoir storage at the end of the period was within 4%, and the deviation in water allocation of each project was within 7%, indicating that the proposed model can meet the calculation accuracy requirements of urban short and medium term water supply dispatching simulation.
