This paper analyzes three-phase industrial agricultural loads operation, under conditions of feeding with unbalanced voltages. Simulations are made in the circuits operating with balanced and unbalanced voltages and the effects in an three-phase induction motor and in an three-phase rectifier are analyzed. The oscillation in steady-state torque in the three-phase induction motor and the generation of triplen harmonics components in the three-phase six pulses rectifier are distinguished as important effects of the operation of these loads with three-phase unbalanced voltages.
Palavras-chave : induction motor; power quality; rectifiers; triplen harmonics; unbalanced voltage.
