The control of doubly fed induction generator (DFIG) was complicated. Offline simulation and traditional fullsubstantial fault experiments had their limitations. A semisubstantial realtime platform of doubly fed wind generation based on dSPACE1007 was constructed in the environment of powerful MATLAB/Simulink. Data interface and control of debugging motors with winding faults, dSPACE and Simulink software together were solved. The experimental results indicated that the platform funtion well in the working condition of stator or rotor winding interrnal faults through changing control parameters and algorithms by control Desk, which provided hardware platforms for fault detective and fault tolerance of DFIG.
