用于淡水分配的加压管网可以利用传感技术和数据解释的最新进展来评估其性能。本文提出了一种基于泄漏场景伪造的泄漏检测和传感器放置方法。该方法包括泄漏检测过程中的建模和测量不确定性。使用模拟数据在全规模供水网络上测试了所提出方法的性能。研究结果表明，在监测整个管网 14 条管道（295 条管道）的流速时，泄漏被限制在几个潜在位置内。案例研究表明，对于 50 L/min 或以上的泄漏，预计具有良好的可检测性。对测量配置的研究表明，如果安装额外的管道，也可以检测到较小的泄漏水平。 (C) 2013 Elsevier Ltd. 保留所有权利。
Pressurized pipe networks used for fresh-water distribution can take advantage of recent advances in sensing technologies and data-interpretation to evaluate their performance. In this paper, a leak-detection and a sensor placement methodology are proposed based on leak-scenario falsification. The approach includes modeling and measurement uncertainties during the leak detection process. The performance of the methodology proposed is tested on a full-scale water distribution network using simulated data. Findings indicate that when monitoring the flow velocity for 14 pipes over the entire network (295 pipes) leaks are circumscribed within a few potential locations. The case-study shows that a good detectability is expected for leaks of 50 L/min or more. A study of measurement configurations shows that smaller leak levels could also be detected if additional pipes are instrumented. (C) 2013 Elsevier Ltd. All rights reserved.
