聚类分析法选择给水管网压力监测点

Pressure Monitoring Points Selection by Clustering Analysis Method in Water Supply Network

压力监测点是反应给水管网运行状态的一个窗口,如何正确的选择压力监测点成为众多国内外学者研究的热点。但是采用复杂的数学公式、建立庞大的矩阵模型而得到压力监测点的选择方式,阻止了众多优化方法在实际中的应用。通过建立给水管网水力模型,进行三种工况的水力计算,并采用聚类分析的方式划分压力分区,分析每种工况下分区情况,结合实际要求,在区域中选择了12个压力监测点,并将其运用于实际工作中,对现实管网中监测点的设置具有指导意义。

Pressure monitoring points reports the situation of water supply network. How to select the points has become a hot spot to may scholars at home and abroad. But the method by using complex mathematics formula, huge matrix model to select the points is not easy to optimize and promote in daily application. In Research, 12 points were selected with actual demands by establishing water supply network hydraulic model, hydraulic calculation under 3 working conditions, using clustering analysis methods to divided some pressure zones, analyzing each zone in every conditions. The method can be a guiding method in reality when be applied in engineering.
