供水管网系统微观模型综合工况分析

Working-state analysis of water supply network systems basis on microscope model

在分析微观模型基本理论及其对供水管网系统进行模拟的基础上，为便于计算机对供水管网系统进行水力模拟，提出将供水管网系统中几大特殊系统组件包括供水泵站、加压泵、蓄水池、阀门等的工况特性描述为节点和管段工况特性模式的供水管网图。建立了连续性方程的一般形式，给出了节点水压法求解工况模型的思路。最后对管网系统进行工况分析，为管网运行调度及研究水质模型打下良好的基础。

Based on the analysis of basic theory of microscope model and simulation of water supply network systems by it, this article presents system map that describes system subassembly as nod and pipe, and uses the method of nodal pressure to solve the working-state model in order to facilitate computer to realize hydraulic simulation. After Finally, the results of simulation is used to analyze the working-state of water supply network systems,which founds a basis for further operation dispatch and water quality model for pipe networks.
