Abstract

Energy recovery and pressure management are essential to achieve sustainable improvements in the development of water distribution systems (WDS). An alternative that has been studied worldwide is the use of pumps as turbines (PAT) replacing pressure reducing valves (PRV) to conciliate pressure control and energy production. This work aims to investigate the current and most recent literature regarding the use of PAT, addressing technical and economic implications that the technical-scientific community has analyzed. The search terms used in the Scopus and Web of Science databases were {‘pump as turbine’ AND ‘water supply network’, ‘water distribution network’ OR ‘water distribution system’}. A total of 59 papers were analyzed, highlighting the operation of PAT as well as selection and location methods, with the evaluation of electricity production, decreased leaks, and especially a suitable cost/benefit ratio. The review indicates that PAT have been infrequently used in real systems. However, the application is greatly feasible from the technical and economic points of view, and in a scenario of variable-speed PAT, the amount of energy produced is high. Future research should be directed to the optimization of new PAT settings so they can better deal with the operational variations in the systems.

水泵在配水系统中作为能量回收的涡轮机:综述

能源回收和压力管理对于实现配水系统(WDS)发展的可持续改进至关重要。世界范围内正在研究的一种替代方案是使用泵作为涡轮机(PAT)取代减压阀(PRV)来协调压力控制和能源生产。这项工作的目的是调查目前和最近关于PAT使用的文献，解决技术-科学界已经分析的技术和经济影响。在Scopus和Web of Science数据库中使用的搜索词是{' pump as turbine ' and ' water supply network '， ' water distribution network ' OR ' water distribution system '}。共分析了59篇论文，重点介绍了PAT的运行以及选择和选址方法，评估了发电量，减少了泄漏，特别是合适的成本效益比。审查表明，PAT在实际系统中很少使用。然而，从技术和经济的角度来看，应用是非常可行的，并且在变速PAT的情况下，产生的能量量很高。未来的研究应针对新的PAT设置的优化，以便它们能够更好地处理系统中的操作变化。
