文摘

Empirical wavelet transform (EWT) is generalized for power quality (PQ) analysis. Generalized EWT (GEWT) adapts according to the input signal information. GEWT based instantaneous PQ indices are suitable to assess several PQ disturbances. Estimation of time varying PQ indices is computationally fast and accurate.
