Pumps as turbines regulation study through a decision-support algorithm

The water distribution network (WDN) is subject to leakages due pipes breaking, which induces a wastage of and overconsumption power for pumps. Leakages are directly related pressure in the pipes. To reduce leakages, reducing valves (PRV) installed networks However, reduction loss energy wasted within PRV. recover part this energy, can be replaced by using pumps as turbines (PATs). Since head flow rates variable WDN, it necessary regulate PAT, does not function properly under upstream conditions. In paper, hydraulic regulation (HR) hydraulic-electric (HER) methods studied economic production terms. A comparison between HR HER based on results from two real sites. study carried out an innovative decision-support algorithm, described detail. show that adding electrical improves production, but increase installation costs makes sites less economically viable.
