초록

STATCOM(static synchronous compensator : one of the custom power equipment) can be used for balancing unbalanced loads. Compensation current references are given by the analysis of the unbalanced 3-phase currents. And for detecting negative-sequence components, a digital Butterworth Filter is designed. Finally a negative sequence component of an unbalanced load current is acquired using the digital Butterworth Filter.
