    摘要: There is provided a yaw rotation control method for a wind turbine generator that does not require a yaw motor and is advantageous for a reduction in cost and a reduction in size and weight of a nacelle. A control unit performs, according to a deviation between wind direction information (θw) obtained from a wind direction detecting unit and a present state yaw angle (θz) obtained from a yaw rotating position detecting unit, yaw rotation control for outputting pitch angle command values (θ1, θ2, and θ3) of yaw rotation to a pitch driving unit and directing front surfaces of rotation surfaces of wind turbine blades at the time of start. This yaw rotation control includes a step of controlling pitch angles of the wind turbine blades at a predetermined azimuth angle.
