To address the limitations of existing deep learning methods in feature extraction and sample similarity modeling for wind turbine gearbox fault diagnosis
we propose a Residual Connected Graph Attention Network (ResGAT) that incorporates multiple distance metrics. This approach constructs a fully connected graph to generate an adjacency matrix and integrates various distance metric methods to fully explore the similarity between samples. Utilizing graph attention networks for node feature aggregation
coupled with residual connections
mitigates the risk of gradient vanishing. Furthermore
L2 regularization and bias correction are incorporated into the Adam optimizer to mitigate overfitting issues. Experimental results demonstrate that the ResGAT method effectively captures sample similarity on the WT-Planetary gearbox dataset and exhibits outstanding performance in fault diagnosis.
