本文提出了一种新的概念，自适应配水网络的动态可重构拓扑结构的最佳压力控制，泄漏管理和提高系统的弹性。实施地区水表区（DMA）大大帮助了供水公司减少渗漏。DMA将水网络隔离成小区域，监控每个区域的流入和流出，并从最小夜间流量中导出阈值以触发泄漏定位。DMA方法的一个主要缺点是网络连接中的冗余减少，这对网络弹性、事件管理和水质恶化产生了严重影响。所提出的自适应可重构网络的方法集成了DMA的好处，管理泄漏与大规模的环状网络的优势，增加冗余的连接，可靠性和弹性。自行供电的多功能网络控制器的设计和集成与新的遥测工具的高速时间同步监测的动态水力条件。提出了一种基于序列凸规划的高效鲁棒优化方法，并将其应用于给水管网的动态拓扑重构和压力控制。一项调查进行了使用的业务网络，以评估所提出的方法的实施和效益。
This paper presents a novel concept of adaptive water distribution networks with dynamically reconfigurable topology for optimal pressure control, leakage management and improved system resilience. The implementation of District Meter Areas (DMAs) has greatly assisted water utilities in reducing leakage. DMAs segregate water networks into small areas, the flow in and out of each area is monitored and thresholds are derived from the minimum night flow to trigger the leak localization. A major drawback of the DMA approach is the reduced redundancy in network connectivity which has a severe impact on network resilience, incident management and water quality deterioration. The presented approach for adaptively reconfigurable networks integrates the benefits of DMAs for managing leakage with the advantages of large-scale looped networks for increased redundancy in connectivity, reliability and resilience. Self-powered multi-function network controllers are designed and integrated with novel telemetry tools for high-speed time-synchronized monitoring of the dynamic hydraulic conditions. A computationally efficient and robust optimization method based on sequential convex programming is developed and applied for the dynamic topology reconfiguration and pressure control of water distribution networks. An investigation is carried out using an operational network to evaluate the implementation and benefits of the proposed method.
