The Performance of a Three-Phase Induction Motor under and over Unbalance Voltage
Voltage unbalance is an adverse global phenomenon impacting three-phase induction motor output. Three-phase source voltage may become imbalanced in a variety of respects, while a balanced system preserves stable voltage magnitude and angles in three phases, but a completely balanced state is d...

| description | Voltage unbalance is an adverse global phenomenon impacting three-phase
induction motor output. Three-phase source voltage may become imbalanced in
a variety of respects, while a balanced system preserves stable voltage magnitude
and angles in three phases, but a completely balanced state is difficult to get.
Imbalanced cases may differ in multiple ranges which may practically affect the
motor. So, this work is an effort to analyze the operations with appropriate
propositions. The output of a three-phase induction motor working with an
imbalanced supply grid, MATLAB/SIMULINK is further used for simulation
purposes and programming based on the asymmetrical component approach is
adopted. A new design for system rerating is being proposed. As a case study, a
10 HP three-phase induction motor was used. The findings of the study show
that to determine the output of the induction motor, positive voltage series must
be respected under the voltage unbalance factor (VUF) or proportion voltage
unbalance index with six various voltage magnitude imbalance conditions, the
copper losses of three-phase induction motors were calculated under full load
conditions by simulation. So, the qualified percentage change in total copper
losses for the motor operating under imbalanced and balanced voltages was
determined. |
