Research limitations attributed to the available datasets are discussed. Among the selected data-mining algorithms, the boosting tree algorithm provided the best prediction results. The high-quality permanent magnets are fitted to. Four data-mining algorithms were studied to evaluate the quality of the models for predicting generator brush faults. VENSYS wind turbines are equipped with a directly driven, permanently magnet-excited synchronous generator. To increase the prediction accuracy of the models discussed, a data balancing approach is used. Twenty-four data-mining models are constructed to predict faults up to 12 h before the actual fault occurs. ![]() The datasets used to analyze faults were collected from the supervisory control and data acquisition (SCADA) systems installed at the wind turbines. In the interest of transparency and in accordance with its legal obligations, Elia publishes data about the Belgian electricity market. The results discussed in this paper are based on analyzing generator brush faults that occurred on 27 wind turbines. Predicting generator brush faults early enables timely maintenance or replacement of brushes. In this paper, data-mining algorithms are applied for early prediction of carbon brush faults. Adequately maintaining and detecting abnormalities in the carbon brushes early is essential for proper turbine performance. Carbon brushes are critical components of the wind turbine generator.
