Aiming at the problem of outage of dual-feedback induction generator(DFIG)based wind turbines due to high temperature limiting power, according to aerodynamics, the design method of the cooling system is presented in this paper. The design of wind gathering hood and the automatic ventilation fast response system of the frequency conversion cabinet are the key parts of this system. In this paper, the design method and the force analysis of the wind gathering hood are expounded, and the system adopted PI regulator to realize the fast response of control. During the test phase,the system was installed on the 1.5 MW wind turbine generator. Through collection and analysis of the field data, the results can verify the feasibility and stability of the system. In addition, the system can meet requirements that the room temperature is less than 40 ℃ and the temperature in frequency conversion cabinet is less than 45 ℃. It can also realize the automatic cooling function of the room.
