Applying pressure management reduces lost water and excessive hydraulic pressures in water distribution networks (WDNs). There are currently four different types of pressure management in the literature, i.e. fixed outlet, time modulated, flow modulated, and remote node modulated. The primary device used in pressure management is the pressure reducing valve (PRV) that dynamically controls the outlet pressure by moving up and down its main valve element. In this study, we firstly introduce the dynamic PRV model with four different pressure management types to the source code of EPANET v3.1 software and assess the effect of different valve opening schemes on pressure graphs and leakage quantities. The results showed that dynamic PRV significantly reduces lost water amounts and excessive hydraulic pressures in the WDN when valve opening is continuously adjusted. Our smart PM extension implemented into EPANET v3.1 software is publicly available in Zenodo repositories (https://zenodo.org/record/6243078).

应用压力管理可减少配水网络 (WDN) 中的失水和过高的水压。目前文献中有四种不同类型的压力管理，即固定出口、时间调制、流量调制和远程节点调制。压力管理中使用的主要设备是减压阀 (PRV)，它通过上下移动其主阀元件来动态控制出口压力。在本研究中，我们首先将四种不同压力管理类型的动态PRV模型引入EPANET v3.1软件源代码，并评估不同阀门开启方案对压力图和泄漏量的影响。结果表明，当阀门开度连续调整时，动态 PRV 显着减少了 WDN 中的失水量和过高的液压。我们在 EPANET v3.1 软件中实现的智能 PM 扩展在 Zenodo 存储库中公开可用 (https://zenodo.org/record/6243078)。
