Assessment of unbalance emission level produced by loads using the apparent power components

Abstract

This paper proposes the application of the unbalanced fundamental power as a merit figure to establish a prediction method of the voltage unbalance emission levels produced by the connection of unbalanced loads. The total apparent power, as criterion for optimal compensation, is discussed when it is applied to loads which are sensitive to voltage unbalances such as generators and motors. The analysis of these aspects is made according to recommendations for voltage unbalances.
