Abstract:
Voltage unbalance is one of the parameters analyzed in power quality studies and
represents the difference between the magnitudes of the voltages of a tri-phase electrical
system and the phase shifts between them. It is desirable to have sinusoidal voltages with
identical magnitudes and 120 electrical degree phase shifts between them. However in
practice, there is always a deviation from this ideal case due to characteristics such as
poor distribution of single-phase loads and the presence of transformers, transmission
lines and capacitor banks with assembly differences between phases. These differences
cause losses to both the consumer and to the energy supplier, such as reduced efficiency
of tri-phase induction motors. In order to determine the influence of the network’s
parameters (magnitudes and phase shifts of the three phases) on voltage unbalance and
the values required to reduce or even eliminate it, the present chapter develops and
presents two analysis methods. The influence of each parameter is determined through
incremental sensitivity calculations and the changes needed for reduction are calculated
by analytical solutions. The quantification index considered is the symmetrical
components method. All methods developed were implemented in software and their
validity was tested for a series of unbalance situations.
