Abstract
This paper presents the analysis of the power
quality before and after the installation of distributed photovoltaic
generation units at the delivery point (distributor/consumer) of a rural
property dedicated to milk production in the city of Medianeira, located
in the western region of the state of Paraná. Measurements of the
aspects that describe the energy quality of the property in question,
such as steady state voltage, power factor, frequency, fluctuation, unbalance
and voltage harmonics, and short duration voltage variation were performed.
The values obtained in these measurements were then compared to the limits
considered adequate, according to the procedures of distribution of electric
energy in the national electrical system. To carry out these measurements
an IMS power quality analyzer model PowerNET PQ - 700 G4 was used. It
was found that the
limits of three aspects related to the quality of electric power were
violated prior to the installation of the photovoltaic panels, which are
the power factor, voltage fluctuation and short voltage variations. After
the installation of the system, there were improvements in the steady
state voltage levels. In addition, a reduction of power factor and fluctuation,
imbalance and harmonic distortions of voltage were obtained. The work
is finished suggesting solutions to the most relevant problems related
to product quality.
