摘要：
In order to improve the reliability of wind turbines, avoid serious accidents and reduce operation and maintenance costs, a fault diagnosis and isolation (FDI) method for wind turbines using deep belief network (DBN) is proposed. The DBN employed no knowledge of physical model but historical data without any selection. The proposed method was evaluated in a wind turbine benchmark model, in comparison with model-based algorithms and conventional data-driven methods. Besides, considering the disturbance in real application, extensive evaluation was taken to analyze the robustness of proposed method which applied Gaussian noise to simulate real noise. The simulation results show that the data-driven FDI method based on DBN for wind turbines achieves the highest accuracy, and it keeps stable diagnostic performance in the strong disturbance of noise. © 2019, Harbin University of Science and Technology Publication.
