A dynamical virtual wind turbine system simulation model has been established based on MATLAB / Simulink. The main physical components are modeled and the real-time performance data （SCADA data） are input into the system model for fault detection. The wind data from the wind field have been input into the model to simu- late the running condition of the wind turbine. By modifying the model parameters, the system model can also virtual perform the wind turbine faulty conditions of gear tooth broken. The analysis result shows that the virtual wind turbine system simulation model based on Simulink can simulate the running operations of the wind turbine efficiently. The model can also virtual perform some faulty states to simulate the operations of the wind turbine in faulty conditions. Accordingly, the system model can be used as a detection for wind turbine failure mechanism research.
