초록
In this paper, STATCOH(static synchronous compensator : one of the custom power equipment) is proposed for balancing unbalanced loads. Compensation current references are given by the analysis of the unbalanced 3-phase currents. And for detecting negative-sequence components, digital Butterworth LPF(low pass filter) is used. The predicted current controller in the synchronous rotating coordinates is also proposed. Finally, the effectiveness of STATCOM is verified by the simulations for unbalanced loads.
