Abstract
Determination and investigation of incidents affecting Power Quality (PQ)
is very important for consumers. In this study, estimation of PQ events is
obtained to determine the disturbances of PQ by using Empirical Wavelet Transform
(EWT) and Discrete Wavelet Transform (DWT) methods and with this estimated parameters.
PQ disturbances were examined with Support Vector Machine (SVM), Artificial
Neural Network (ANN) and Adaptive Neuro-Fuzzy Inference System (ANFIS)
classification methods. Voltage signals (sag, swell, interruption, transient
and normal) used in the classification of PQ disturbances were recorded from
grid with the aid of a microcontroller based on device designed with a sampling
frequency of 6.4 kHz. Classification consequences using Machine Learning
Methods show that DWT outperforms over EWT for feature extraction processing
and the classification accuracy is tabled.
Classification by ANN and ANFIS through the use of conjecture parameters
in PQ disturbances based on DWT Method has been recommended.
