| Popis: | In this paper optimized classifier for classification of different power quality (PQ) events is presented. Its implementation is performed in LabVIEW, using an efficient-wavelet based feature extraction algorithm and an optimized random forest (RF) classification method. It is able to classify twenty-one classes of single and combined PQ events. Its accuracy is tested and verified using signals from three different sources, including real PQ events, with and without presence of white Gaussian noise. The verification has shown that this classifier exhibits high classification accuracy, despite the fact that in the process of classification two classes obtained as combination of four disturbances are considered. |
