Abstract


Since the East Vietnam Sea has an advantageous geographical location and rich natural resources, we can develop and manage islands and reefs in this region reasonably to declare national sovereignty. Based on 1096 scenes of QuikSCAT wind data of 2006–2009, wind power density at 10 m is calculated to evaluate wind energy resources of the East Vietnam Sea. With a combination of wind power density at 70 m calculated according to the power law of wind energy profile and reef flats extracted from 35 scenes of Landsat ETM + images, wind power installed capacity of every island or reef is estimated to evaluate wind power generation of the East Vietnam Sea. We found that the wind power density ranges from levels 4-7, so that the wind energy can be well applied to wind power generation. The wind power density takes on a gradually increasing trend in seasons. Specifically, the wind power density is lower in spring and summer, whereas it is higher in autumn and winter.  Among islands and reefs in the East Vietnam Sea, the wind power installed capacity of Hoang Sa archipelago is highest in general, the wind power installed capacity of Truong Sa archipelago is at the third level. The wind power installed capacity of Discovery Reef, Bombay Reef, Tree Island, Lincoln Island, Woody Island of Hoang Sa archipelago and Johnson Reef, Ladd Reef, Petley Reef, Alison Reef of Truong Sa archipelago is relatively high, and wind power generation should be developed on these islands first.
