This paper introduces a novel methodology that integrates low- and high-frequency pressure monitoring in the parts of the urban water distribution network characterized by the largest number of repairing operations. This integrated approach aims to pinpoint the source and characterize potentially dangerous pressure variations. The actual behavior of a real operational water distribution network is considered as an example to verify the effectiveness of the proposed methodology. The analysis of the acquired pressure signals allows for mapping frequent pressure surges and identifying their source in the functioning conditions of a big user. Notwithstanding these pressure variations are not overly large, according to the literature, their near-continuous nature poses a risk of inducing pipe breaks, and then leakage, due to fatigue. The proposed method integrating routine low-frequency measurements with targeted high-frequency surveys provides a cost-effective, proactive management strategy.

绘制城市供水网络中的压力浪涌源：将低频和高频压力数据与说明性真实案例研究相结合


本文介绍了一种新颖的方法，该方法在城市供水管网中修复作业最多的部分中集成了低频和高频压力监测。这种综合方法旨在查明来源并表征潜在危险的压力变化。以实际运行的供水管网的实际行为为例来验证所提出方法的有效性。对获取的压力信号进行分析可以绘制频繁的压力波动图，并在大用户的功能条件下识别其来源。尽管这些压力变化并不是太大，但根据文献，它们接近连续的性质存在导致管道破裂的风险，然后由于疲劳而导致泄漏。所提出的方法将常规低频测量与有针对性的高频调查相结合，提供了一种具有成本效益的主动管理策略。
