OLIVEIRA FILHO, Delly et al. Methodology for energetic diagnosis for a water pumping station. Rev. bras. eng. agríc. ambient. [online]. 2011, vol.15, n.10, pp.1097-1103. ISSN 1415-4366. http://dx.doi.org/10.1590/S1415-43662011001000015.
This study aimed to develop a methodology to diagnose energetically a water supply system for a irrigation system and for a city. The steps taken were: (i) the energy quality supplied by the utility in relation to level and unbalanced of the supplied voltage; (ii) the electrical energy consumption and demand for the pumping station; (iii) the study of the electrical and hydraulic load's characteristics; (iv) the tariff and demand contracts optimization; (v) the water storage capacity; and (vi) the working hours management. This methodology was tested and validated for the water pumping station in a town of about 70,000 inhabitants. Among the proposed actions, which saved the most, were: (i) the sizing of pumps and motors; and (ii) the optimization of tariff and demand contracts. It was noted that this methodology is simple and easy to apply and there is a great potential for saving energy up to 52%
