ABSTRACT

Harmonic emission levels assessment is significant for harmonic mitigation. Traditional assessment methods are easy to be impacted by the background harmonics. Besides, when the harmonic sources are correlative to each other, the calculation errors increase. To solve this problem, a sparse blind source separation based method is applicated in this paper. This method can obtain accurate calculation results even when the background harmonics fluctuate greatly and the harmonic sources are related to each other. Simulation analysis verifies the validity of the proposed method.
