Disclosed are an emergency control method used when a pitch system of an aerogenerator malfunctions and an apparatus applied to the same. According to the present invention, the emergency control method used when a pitch system of an aerogenerator malfunctions and the apparatus applied to the same perform rotation control of a blade by a transient response characteristic predetermined by one threshold switch contact when a pitch system of an aerogenerator malfunctions. Accordingly, the present invention can improve stability of feathering control to stop the aerogenerator, can prevent the size of angular speed from rapidly changing at a point passing the threshold switch contact, and does not require performing reverse rotation control due to a blade passing through a target point by rotary inertia at all. |
