Dimensionamento de sistemas fotovoltaicos isolados para alimentação de containers utilizados em canteiro de obra

Abstract

This work aims to present an alternative for the implantation of containers in construction sites where it is difficult to connect electrical energy provisionally at the beginning and in great part of the course of the work. First, it is proposed the design of containers in a way specific to their use in the construction site. Variations in the form of changing rooms, office, refectory, bathrooms and workshop will be discussed. The electrical consumption of each container will take into account lighting loads, general purpose outlets and specific use circuits. For the electrical system, a photovoltaic power generation system will be proposed in isolation from the utility grid, with the use of a battery bank. Individual systems will be designed for each container, and in the module used for the bathroom, an additional water heating system will be designed for the showers by means of solar thermal collectors, where there will be an electrical rearguard independent of the photovoltaic system, that is, the showers will receive power when there is power from the utility. The photovoltaic system will be designed in a fixed way and that the best use of the system will be made. A specific scenario will be defined for the study, where the analysis and design parameters of the whole system will be defined.
