摘要：

So far, an accurate and applicable harmonic phasor estimator for power system monitoring is still missing. To address this problem, this paper proposes a harmonic phasor estimator based on the frequency-domain sampling theorem. Dynamic harmonic phasors are modeled by complex exponential functions. Simulation tests show that the proposed method is more accurate and more applicable than the sinc interpolation functions-based algorithm. A theoretical analysis is also presented to discuss the harmonic phasor estimation errors under ideal conditions.
