Dimensionamiento e instalación de un sistema híbrido solar fotovoltaico y eólico para el suministro de energía en una institución educativa ubicada en la localidad de Usme

Abstract

The district of Usme is located in the southeast of the city of Bogota and is considered one of the districts with the largest surface area since it is composed of seven UPZs, five of which are residential, one of which is predominantly residential and the last one is for development. Likewise, it is important to highlight that Usme has a large rural area which is very significant due to the diverse land uses and its great ethnic variety, however, it has been called a vulnerable area in the educational and socioeconomic sphere because it lacks a continuous energy supply which triggers a high rate of child dropout.

On the basis of the problems presented in the sector with regard to the intermittent operation of electricity lines, the University of Santo Tomas took the initiative to help and support projects that prioritize the disadvantaged communities; This work was developed in collaboration with the social projection centers and the Environmental Engineering faculty. In this case, the Usme Union was chosen as a rural educational institution, where it benefited the population since it significantly improved the energy deficiency that was presented by the development of the installation of a hybrid system together with an instructive manual for the proper management of it; following this was carried out a training of the educational staff with a video.

It can be seen that the Union has meteorological conditions suitable for carrying out the project; the wind speed measurement was maintained between 2.5 m/s and 7 m/s and an average radiation of 4 Wh/(m2*day). For the installation of the hybrid system, resources were allocated for the purchase of 2 solar panels of 365 W each monocrystalline with efficiency of 95%, a 400 W turbine with 60 cm radius and 23% efficiency, two 150 Ah 12 V batteries and a 60 Ah 12/24 V controller, however, The inverter that was purchased is 600 W which means that not all the equipment can operate simultaneously. By installing the hybrid system it was possible to establish that it has the capacity to generate 3.069 WH/day.
