In the development of wind power projects,tower shadow effect analysis is crucial.Based on the actual 10-minute wind measurement data of the wind measurement towers in a wind farm,and following the wind resources evalua-tion standards of the wind power industry and the requirements of the international IEC for wind resource data evalua-tion,Windographer software is adopted to analyze the wind data measured by different anemometers installed at the same height but different directions in the same measurement tower.The wind speed correlation between two anemometers with different directions are compared firstly.Then,standards and software are used to process the wind directions of the tow-er shadow effect,and the wind speed results of the anemometers after fitting that is not affected by the tower shadow effect are obtained.The results are then compared with the wind speed affected by the tower shadow effect.The tower shadow effect on the wind speed is thus obtained.
