摘　　要：借助计算机仿真软件,对张家口市某小区庭院管网水力特性进行了仿真。建立了循环水泵、压力节点及常用阀门的数学模型及仿真模型,通过模型组态实现了庭院管网的动态仿真。仿真运行数据表明,该管网存在一定程度的水力失调。通过对入户阀门及各分支阀门的开度调整,实现了管网的水力平衡,调整结果为实际管网节能运行提供依据。In this paper,the computer simulation software is used to simulate the hydraulic characteristics of a courtyard pipe network in a community in Zhangjiakou City.The mathematical models and simulation models of circulating water pumps,pressure nodes and commonly-used valves are established,and the dynamic simulation of the courtyard pipe network is realized through the model configuration.The simulation operation data shows that there is a certain degree of hydraulic imbalance in the pipe network.By adjusting to the openings of the inlet valves and each branch valve,the hydraulic balance of the pipe network is achieved,which provides a basis for the actual energy-saving operation of the pipe network.
