Abstract :
It is proposed in this paper a generalization of classical power compensation theory considering current and voltage unbalanced systems. The work demonstrates that for these systems the optimum compensation does not implies in null neutral currents. It was also possible to conclude that the classical theory can be expanded for different compensation situations since the systems constraints are properly used. In this work, aiming to validate the proposal, some non-active power compensations were performed and evaluated through simulation results of a hypothetic system.
