In this paper, firstly it is tried to classify pure sine and power quality disturbances (PQD) such as voltage sag, voltage swell, voltage with harmonics, transients and flicker at power system frequency (50 Hz). Wavelet transform (WT) is used to extract distinctive features. Wavelet energy criterion is applied to wavelet detail coefficients. It is seen that classification performance of support vector...
W artykule przedstawiono podstawowe informacje związane z dyskretną transformatą falkową oraz opisano jej zastosowanie w przypadku klasyfikacji patologicznych cykli w analizie sygnału EKG. Artykuł zawiera porównanie wyników klasyfikacji przeprowadzonych na tych samych próbkach z użyciem różnych funkcji falkowych oraz różnych klasyfikatorów.
