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 controls the pitch angle to a feather side to reduce the rotational speed of the wind turbine blades to a predetermined speed upon receiving a stop signal instructing stopping the rotation of the wind turbine blades, and, on the basis of a detection result of an angle detection device, a brake disc and a brake device are driven and controlled so that the rotation of the wind turbine blades is stopped at a desired position.
