In Tibetan Plateau and the northern part of Northwest, and Northeast China, the wind power density is normally at 150-200 W/m2, and up to 6500 hours yearly, the wind speed can reach above & equal to 3 m/s. Due to the high altitude and thin air density, the wind power density is comparatively weak. The air density at 4000m is only 67% of that of the sea-level. For example, the 8m/s wind can generate 313.6 W/m2 at sea-level whereas 209.3 W/m2 at 4000m
The wind speed in Tibetan Plateau is the highest, while the wind power is far below the coastal Southeast.
Anhui Hummer Dynamo Co., Ltd. Specially designs the Model Plateau Fortune to meet the regional features—“even annual wind speed, long valid hours, and low valid wind power density? It is really a great innovation.
