Dimensionamento de sistema de bombeamento de água utilizando energia solar

Abstract

In regions that have difficult access to hydro sources and connection to the electric power distribution network, photovoltaic solar energy is one of the energy alternatives with low environmental impact compared to conventional sources. The objective of this end-of-coursework was the sizing of a water pumping system powered by a photovoltaic energy Generation system, located in the Medianeira campus of the Universidade Tecnológica Federal do Paraná (UTFPR). The methodology used for the accomplishment of the work is composed of four steps, which are: the determination of the hydraulic requirements as reservoirs size, flow rate of 2.7[m3.ℎ−1], supply time, piping and manometric height, the determination of the electric power required to the motor calculated as 282 W for the transportation of liquid between reservoirs, dimensioning of the photovoltaic system with batteries for three days of autonomy and the automation system. The system automation and batteries account for the largest portion of the implementation cost of R$ 2,361.32. The water pumping system powered by a photovoltaic energy generation system dimensioned in this work is a reduced scale model of the technology and can be used by professors and academics of the university and by the external community an example of application of the technology.
