Agronomy and Electrical Engineering: A Transversal Approach

Soybean (Glycine max L.) is the main agricultural crop in Paraná the second largest national producer. Historical precipitation series from the Water Institute of Paraná were studied for ten municipalities in the region with daily data from 1977 to 2015. The effects of the ENOS phenomenon during its El Niño and La Niña phases on the interannual variation of rainfall and the LTO on the decadal cycles of precipitation in the region were analyzed. A strong influence of ENOS and a weak influence of the LTO on rainfall variability was verified. In view of an international outlook in which ''and increasing consumption of electric energy and the demand for clean and renewable energyThis work will show a complete project of an Uninterruptible Power System (UPS) of 5kV A with the possibility of integrating a photovoltaic system making it less dependent of the grid in the recharge of its battery bank implying a greater autonomy for the load either in residential or commercial use.
