The present invention relates to a brake controlling method for a wind power generator. The purpose of the present invention is to stably generate power by stably and mechanically braking to the torque of the wind power generator until reaching a stable range by applying power to a clutch when a wind speed is a preset wind speed or higher due to strong wind or the number of the rotation of a rotor is a preset number of the rotation or higher to rotate a servo motor without a load. To achieve the same, the present invention includes (a) a step of sensing an ambient wind power speed of the wind power generator by using a wind-environmental factor; (b) a step of determining whether the wind speed is a preset wind speed or higher or the number of the rotation of the rotor is a preset number of the rotation or higher according to the result of the (a) step; (c) a step of partly converting the torque of the rotor into the no-load rotation of the servo motor a condition that power is not on by applying power to the clutch only when it is determined that the wind speed is the preset wind speed or higher or the number of the rotation of the rotor is the preset number of the rotation or higher by the result of the (b) step; (d) a step of sensing the ambient wind power of the wind power generator by using the wind-environment sensing factor after the reduction control through the (c) step to determine whether the wind speed is increased up to the preset wind speed or higher or the number of the rotation of the rotor is increased up to the preset number of the rotation or higher when a reduction control is activated; (e) a step of gradually reducing an interphase voltage of the servomotor to be 0 V when it is determined that the wind speed is the preset wind speed or higher or the number of the rotation of the rotor is the present number of the rotation or higher while the reduction control is activated by the result of the (d) step to completely stop the generator; and (f) a step of converting the braking condition into the initial condition after a predetermined period while the generator is completely stopped through the (e) step to reset the system. |
