Abstract

The interpolated dynamic DFT (IpDFT) is one of the most accurate dynamic synchrophasor estimation methods. But it suffers from infiltration from the second harmonic component. In this paper, the estimation errors of the IpDFT caused by second harmonic interferences are firstly analyzed. Based on this, an improved interpolated dynamic DFT (IIpDFT) synchrophasor estimator that considers second harmonic interferences are proposed. Multiple simulation tests show that, even under large second harmonic interference conditions, the IIpDFT is much more accurate than the IpDFT.
