Abstract:The rotor system of wind turbine is the most fragile parts of wind turbine, and accurate diagnosis of its fault categories can improve the effectiveness of wind turbine maintenance. A multi-component fault diagnosis method based on the three-phase currents data of wind turbine was proposed for various fault categories of induction motor and planetary gearbox. The method extracted feature vectors from three-phase currents data by deep auto-encoder and used support vector machine for fault classification. The above method was verified by an example of a rotor driver of wind turbine. The experimental results show that the method can accurately identify and diagnose the fault categories of rotor driver under variable load and variable speed environment.
