供水管网健康监测的流量监测点优化布置

Optimal arrangement of flowrate monitoring points in health monitoring of water supply network

提出了以城市供水管网健康监测为目的的流量监测点优化布置的一个实用方法,方法通过假设在管网的不同位置存在不同程度的局部漏损,并逐管段假设流量监测点,根据局部漏损对监测点流量的影响度最大为目标来实现流量监测点的优化布置。通过算例分析对方法的有效性进行了验证,并与流量监测点优化布置的摄动方法进行了比较。研究表明,与文献摄动方法相比,本文方法更简单、也更实用,可用于供水管网健康监测的流量监测点优化布置。

This paper presents a practical method for optimal arrangement of flowrate monitoring point in health monitoring of urban water supply network. Assuming local losses exist at different positions, and monitoring points are arranged one by one at each pipe, this method determines the optimal monitoring point arrangement scheme by evaluating the maximum influence of all local losses on the flow rate of each monitoring point. The method is validated through comparison with the perturbation method. It is shown that this method is simpler and more reliable, and can be used for the health monitoring of theowater distribution system.
