Abstract:

The composition of the DFIG model is given, the principles of the drive-train, generator, converter and the control system are introduced, and the mathematical and Simulink models are built. The LVRT technology of wind turbine is introduced and previewed; the fault model of the grid is built. The fault behavior of the DFIG is simulated and analyzed, and the fault optimization strategy is tested and verified. This research is useful for the simulation of wind turbine and makes a good preparation for the stability analysis on the wind farm.

Key words: Wind turbine, electrical model, mathematical model, simulation
