Abstract :
Input voltage unbalance and sag conditions because of the power system line faults may lead to mal-operation of adjustable-speed drive (ASD´s). In this paper, the effect of balanced and unbalanced sags on the performance of ASD´s has been discussed. The improved performance of ASD´s with ultracapacitors is demonstrated using MATLAB simulation.
