Resumen
The restructuring of the electricity system in several countries, including Brazil, brought
new challenges to the electricity distribution system. A new alternative, which has
become a trend in recent years, has been distributed generation (DG), whose system is
characterized by the installation of small generators close to the final consumer. The
correct performance of the protection scheme plays a vital role in detecting and isolating
short circuits, preventing and limiting defects. Correct performance means that
abnormally operated equipment or circuits will stop working in the shortest possible time.
In this sense, the objective is to develop a protection project for a distributed generation
system, involving photovoltaic cells in a full substation. In addition to using the
bibliographic review methodological procedure, a case study was presented for a full
substation, in which the power, short circuit, protection and selectivity analyzes necessary
for the implementation of a photovoltaic system are presented. It is concluded, through
the obtained results, that there are benefits in the use of the photovoltaic system, such as
reduction of losses by transmission, reduction of expenses with energy, less
environmental impact and useful life of the system above 25 years.
