Zusammenfassung:	The invention relates to a method for stopping the rotor of a wind power plant when the blade angles are in the operating position and the tower is inclined to the direction of the wind. According to the invention, in the method, the blade angles of the blades of the rotor are adjusted from the operating position towards the storm position so that at the first step, the blade angles are turned at the first blade angle speed so that the rotor brakes; at the second step, the blade angle speed is reduced so that while in the operating position, the rotor acts to soften the pendulous motion of the tower against the wind; and at the third step, as the pendulous motion of the tower turns to be parallel to the wind, the blade angle speed is increased to enhance the braking.
