WIND TURBINE GENERATOR AND METHOD OF CONTROLLING THE WIND TURBINE GENERATOR

摘要

37 A wind turbine generator capable of easily stopping wind turbine blades at an appropriate position in a short time is provided. A pitch control device (11) controls the pitch angle to a feather side to reduce the rotational speed of the wind turbine blades (5) to a predetermined speed upon receiving a stop signal instructing stopping the rotation of the wind turbine blades (5), and, on the basis of a detection result of an angle detection device (12), a brake disc (13) and a brake device (14) are driven and controlled so that the rotation of the wind turbine blades (5) is stopped at a desired position.
