To prevent wind turbine blade accidents and improve fault detection accuracy, a hybrid deep learning model based on 1D CNN-BiLSTM-AdaBoost for turbine-blade classification is proposed. Fault data are first preprocessed by segmenting labeling the patterns. Features extracted through convolutional layers, followed dimensionality reduction denoising using pooling feature fusion. The multi-source sensor features then fed into BiLSTM layer further processing of time-series characteristics. processed classified fully connected layer. Finally, multiple weak classifiers combined to generate final result. Experimental results show that outperforms models use only CNN, BiLSTM, CNN-BiLSTM, achieving an accuracy 96.88%, precision 97.22%, recall 96.92%, F1 score 96.86%, with maximum 100%. These validate model’s effectiveness classification.
