| description | The invention discloses a wind direction angle calculation processing method and system for a wind turbine generator. The calculation processing system comprises a polar-straight coordinate conversion module, a mean value calculation module and a straight-polar coordinate conversion module. The polar-direct conversion module uses the conversion relation between the polar coordinate system and the rectangular coordinate system to take the wind direction angle measured by the anemoscope as the angle value under the polar coordinate system and convert the angle value into the data under the rectangular coordinate system. And performing wind direction mean value calculation on the wind direction angle data under the rectangular coordinate system through a mean value calculation module to obtain wind direction values with different time mean values. And the straight polar coordinate conversion module calculates the downwind angle value of the polar coordinate system according to the downwind coordinate value of th |
