based on Balanced Iterative Reducing and Clustering using Hierarchies (BIRCH)
Mel spectrograms
Siamese networks
and the Convolutional-based Multi-scale Attention Mechanism (CBAM). The model achieves early fault warnings for blade icing through labeling pre-icing states
down-sampling normal data
measuring similarity using the Siamese network
and selecting features with the CBAM attention mechanism. Comparative analysis results indicate that while maintaining low computational costs
the model can accurately predict icing faults up to 42 minutes in advance. This model provides more reliable early warning information for the efficient and stable operation of wind turbines
