Resumo:
Distributed generation has grown every year as a way of diversifying the energy matrix,
with photovoltaic energy being one of the most promising as it is a clean energy that is
easy to use. Small and medium-sized photovoltaic plants have been built both in urban
centers for direct use at the generation site, as well as in more distant regions, in which
the energy produced is transferred to the existing electricity grid of local concessionaires.
The growth of this type of generation plant, interconnected to existing grids, requires
studies to assess disturbances that may affect the grid and, consequently, the photovoltaic
systems. In this aspect, this work aims to implement a complete photovoltaic generation
system model and an electrical distribution network in the ATP R software, through its
ATPDRAW graphical interface, in order to analyze the behavior of these systems, against
transient disturbances that affect its operation in the electrical network. The software used
has great advantage in the implementation and simulation of electrical events, through
existing components, or the creation of new ones through mathematical equations. With
that, through mathematical models, were implemented through equations, components
that represent the real characteristics, for the operation of the system as a whole. The
application of certain elements for the protection of photovoltaic systems from electrical
disturbances caused in the distribution network was thus observed and validated.
