由于渗漏造成的水损失是所有配水管网 (WDN) 中实际观察到的常见现象。然而，如果在泄漏发生后最短的时间内检测到泄漏的发生，则可以显着减少泄漏量。基于水平衡中不同消耗的判别行为，提出了一种用于 WDN 泄漏检测的集成自下而上水平衡模型。采用自适应矩估计（Adam）算法来评估模型中的参数。通过分析评估参数的当前值和上升率，可以检测异常事件（例如泄漏、非法使用或计量不准确）。此外，提出了一种一步慢策略来估计压力传感器的加权系数，以提供泄漏的近似位置信息。该方法应用于基准WDN和实验WDN以评估其性能。结果表明，可以近乎实时地检测到相对较小的泄漏。此外，该方法能够识别泄漏附近的压力传感器。
Loss of water due to leakage is a common phenomenon observed practically in all water distribution networks (WDNs). However, the leakage volume can be reduced significantly if the occurrence of leakage is detected within minimal time after its occurrence. Based on the discriminative behavior of different consumption in water balance, an integrated bottom-up water balance model is presented for leak detection in WDNs. The adaptive moment estimation (Adam) algorithm is employed to assess the parameters in the model. By analyzing the current value and the rising rate of the assessed parameters, abnormal events (e.g., leak, illegal use, or metering inaccuracy) could be detected. Furthermore, a one-step-slower strategy is proposed to estimate the weighted coefficient of pressure sensors to provide approximate location information of leak. The method was applied in a benchmark WDN and an experimental WDN to evaluate its performance. The results showed that relatively small leak could be detected in near-real-time. In addition, the method was able to identify the pressure sensors near to the leak.
