Terrain of wind farm is one of the most important factors infecting the power performance of wind turbine. According to the standard of IEC 61400-12-1,this paper fts a plane through the center of wind turbine basement based on SRTM data and method of PCA(Principal Components Analysis)of MATLAB, then calculates terrain slope and altitude deviation of 20 times of rotor diameter around wind turbine with an example, provids some references for site evaluation of wind turbine power performance test.
