Análise do desempenho de uma motobomba de superfície acionada por um motor CA indução tipo shaded pole alimentado por painel fotovoltaico

Abstract

The proposed work evaluates the technical viability of a photovoltaic pumping system and presents the main characteristics of the system application. The pumping system uses a lead acid battery and a photovoltaic panel. The battery supplies energy to an alternating current motor, namely Shaded Pole, which feeds the centrifugal surface pump. The energy from the battery is changed to AC voltage by a DC-AC inverter, 12/220 V. The voltage level applied on this battery is monitored by a load controller (solar power regulator). The whole proposed system is made in Brazil, which facilitates the purchase, alteration and building of the system. The amount of water pumped is related to the solar radiation, the solar exposition period, the manometric height and the pumping power. By evaluating the proposed system is possible to find the volume of pumped water and how this amount will be applied at small rural municipalities, as human and animal water consumption, irrigation, among others.
