摘要/Abstract

摘要： 水力水质模型构建及模拟是研究供水管网性能的重要手段. 为了实现在MATLAB环境中调用EPANET水力水质计算引擎，研究矿井防尘供水管网水力水质特征，实现并对比分析了两种有效的EPANET-MATLAB对接方法，并基于其中面向对象的数据结构调用方式混合编程，构建了矿山井下防尘供水管网水力水质模型；结合防尘管网日用水需求，对水力工况和水龄分布分别进行了24h和48h动态模拟. 研究表明:使用EPANET-MATLAB Toolkit的混合编程更加灵活、高效，是进行水力水质模拟与分析的有效途径；防尘供水管网用水具有周期性，呈现明显的高峰和低峰时段；用水节点的水压变化范围约为1.5~5.5MPa，其变化规律与用水量变化呈负相关；水龄变化也具有日周期性的特点，不同用水节点的水龄呈现不同的波动特征；用水节点距离水源越远，其水龄相对较大，所有用水节点的水龄都在15h以内.

Abstract: Hydraulic and water quality simulation is an important method to study the performance of water supply network. In order to call the EPANET calculation engine of hydraulics and water quality analysis in MATLAB environment， so as to study the characteristics of mine water supply network for dust control， two types of effective EPANET-MATLAB hybrid programming methods were realized and compared. Based on the one adopting the object-oriented data structure， EPANET was called to establish hydraulic and water quality models of mine water supply network for dust control. According to the daily water demand of the network， dynamic simulations of hydraulic operating condition and water age distribution were carried out for a duration of 24h and 48h respectively. Research results show that the hybrid programming using EPANET-MATLAB Toolkit is more flexible and efficient to simulate and analyze the hydraulic behaviors and water quality. Water consumption of the network shows a periodic feature with obvious peaks and troughs. The variation range of the water pressure at demand nodes is between 1.5~5.5MPa， and the variation rule is negatively correlated to water consumption. The change of water age also shows a diurnal periodicity. Generally， the longer the distance between the demand node and the water source is， the bigger the water age is. The water age of all demand nodes is lower than 15h.
