“Wind Turbine Generator And Yaw Rotation Control Method For Wind Turbine Generator”

Abstract: 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 (20) performs, according to a deviation between wind direction information (θw) obtained from a wind direction detecting unit (30) and a present state yaw angel (θz) obtained from a yaw rotating position detecting unit (40), yaw rotation control for outputting pitch driving unit (21) and directing front surface of rotation surfaces of wind turbine blades at the time of start. This yaw rotation control includes a step of controlling pitch angels of the wind turbine blades at a predetermined azimuth angle.
