过程和传感器故障的同时可检测性:在供水管网中的应用

Simultaneous Detectability of Process and Sensor Faults: Application to Water Distribution Networks

Krishnan Srinivasarengan, Taha Boukhobza, Samir Aberkane, Vincent Laurain

摘要:

使用传感器检测供水管网(WDN)中的泄漏已成为有效管理水资源的关键。使用该数据的泄漏检测方法依赖于所获取数据的正确性。然而,这一假设在实践中往往被违反。因此,传感器故障下的泄漏检测是一个具有实际意义的问题。这涉及到更一般的问题,同时检测传感器和过程故障的一类系统建模为一个网络,通过利用冗余,通过传感器之间的拓扑关系。因此,本文的目的是i)WDN建模为包含系统和传感器故障的图,ii)提供理论联合检测结果,这样的图和iii)将这些结果应用到泄漏识别的情况下,传感器故障条件下的实际数据从农村WDN发出。

英文摘要:

Detecting leaks in Water Distribution Networks (WDN) using sensors has become crucial towards an efficient management of water resources. The leak detection methods that use this data rely on the correctness of the acquired data. However, this assumption is often violated in practice. Consequently, leak detection under sensor faults is a problem of practical importance. This relates to the more general problem of simultaneous detectability in sensor and process faults for a class of systems modelled as a network, by exploiting the redundancies available through the topological relationship between the sensors. This paper hence aims at i) modeling WDN as graphs containing both systems and sensors faults ii) providing theoretical joint detectability results for such graphs and iii) applying these results to the scenario of leak identification under sensor faults conditions on real data issued from a rural WDN.
