摘　　要：采用Water GEMS软件对自行搭建的供水管网进行模拟,利用压力传感器和超声波流量计实时监测管网的节点压力和用户流量,并将上游节点压力和用户用水量导入模拟软件,通过调节仿真模型中的参数来校核管网压力,使整个管网的模拟压力与实测压力具有较高的拟合度,从而实现对管网压力的实时模拟,为预测爆管、优化调度、降低漏损等提供依据。结果表明:利用Water GEMS软件可以快速搭建供水管网压力模型,通过逐段校核,利用压力模拟供水管网的实际运行可以达到较高的拟合精度。The Water GEMS simulation software was used to simulate the self-built water supply network,and the pressure sensor and ultrasonic flow meter were used to monitor the node pressure and user flow of the pipeline network in real time.The pressure and user water consumption of upstream node were imported into the simulation software.The pressure of the pipeline network was checked by adjusting the parameters of the simulation model.The simulated and measured pressure of each pipeline network had a high degree of fit,thus realizing the real-time simulation of the pressure of the pipeline network,providing a basis for predicting pipe burst,optimizing dispatch,reducing leakage and so on.The results showed that the Water GEMS software could be applied to build the pressure model of water supply network quickly.By checking section by section,the actual operation of water supply network could be simulated by pressure,and could achieve a good fitting accuracy.
