Abstract
The quality of power is the major challenging issue in the power system. In real-world power systems, it is ordinarily impossible to maintain perfect balance in phase voltages and currents. The variety of the loads in the networks enhances the amount of unbalance or negative sequence components. In conjunction with asymmetrical load, further increase in negative sequence components is introduced due to the network inherent asymmetry. The power quality is very much affected by the magnitude and phase disturbances of three phase voltage and current respectively. The proposed balancing compensator is built as reactive device uses the shunt current source compensation whose instantaneous values are determined by the instantaneous symmetrical component theory. The compensation configuration developed in this paper is tested for its cogency on 3-phase,3-wire circuit through wide-ranging simulations for phase outages scenarios. The simulation results for the compensation theory and the ideal compensator verify the proposed compensation method. In this paper, a general analysis of control strategy to mitigate negative-sequence and zero sequence currents in unbalanced three-phase power systems is proposed.
