Abstract:

In order to effectively extract the fault features of time series data in supervisory control and data acquisition (SCADA), considering the advantages of one-dimensional convolutional neural network (1-D CNN) for extracting local time series features and the advantages of long-term memory (LSTM) which can extract long-term dependent features, a method for fault diagnosis of wind turbines based on 1-D CNN-LSTM is proposed. To solve the problem of the scarcity of fault samples of wind turbines based on the siamese network architecture, a wind fault diagnosis method based on siamese 1-D CNN-LSTM is proposed. The proposed siamese 1-D CNN-LSTM method relies on a small amount of sample data to effectively extract the fault features of the wind turbine. The results show that 1-D CNN-LSTM is better than other existing deep learning methods. When the training samples are insufficient, the proposed siamese 1-D CNN-LSTM can significantly improve the fault diagnosis results.
