Detection of contamination events in water distribution systems is a crucial task for maintaining water security. Online monitoring is considered as the most cost-effective technology to protect against the impacts of contaminant intrusions. Optimization methods for sensor placement enable automated sensor layout design based on hydraulic and water quality simulation. However, this approach results in an excessive computational burden. In this paper we outline the application of controllability analysis as preprocessing method for sensor placement. Based on case studies we demonstrate that the method decreases the number of decision variables for subsequent optimization dramatically to app. 30 to 40 percent.
在供水系统中检测污染事件对于保障水安全至关重要。在线监测被认为是最具成本效益的技术，可以防止污染物入侵的影响。传感器布置的优化方法可以根据水力和水质模拟实现自动化传感器布局设计。然而，这种方法会导致计算负担过大。本文概述了将可控性分析应用于传感器布置的预处理方法。通过案例研究，我们证明该方法可将后续优化的决策变量数量大大减少到约 30%到 40%。
