Abstract: In wind resource assessment, high resolution terrain data is usually difficult to be obtained, thus finding the alternative data is particularly important. In view of the fact that it is very difficult to conduct topographic mapping and ground investigation for wind resource assessment, based on the case of a DGS wind farm in mountains with high altitude and complicated terrain in Yunnan province, it is tried to use SRTM data of 90-meter resolution for acquiring the electronic topographic map, which is needed in Meteodyn WT model. A comparison is made of the wind resource assessment results based respectively on the electronic topographic map and the surveyed 1∶10 000 gauss map, which can be concluded that the SRTM data can be used for wind resource assessment in mountains with high altitude and complicated terrain.
