WIND TURBINE GENERATING DEVICE AND METHOD FOR CONTROLLING WIND TURBINE GENERATING DEVICE

摘要

Provided is a wind turbine generating device which can stop a blade at an appropriate position easily and rapidly. When a signal for stopping the rotation of a blade (5) is received, a pitch control device (11) controls a pitch angle so as to turn the blade toward the feathered position, to reduce the rotating speed of the blade (5) to a predetermined speed. Further, a brake disk (13) and a brake device (14) are driven and controlled so as to stop the blade (5) at a desired position on the basis of an angle detected by an angle detecting device (12)
