It is necessary to measure several years of wind data (usually do not consider wind speeds below 6 m/s), wind data at different heights; information on geological conditions; a 20-year investment budget; lifespan of the wind turbine of 20 years). . . This information is used to select the machine model, height, blade diameter and foundation type. . . .
Wind turbines typically can't operate at full capacity 365 days a year, so where do the energy resources come from when the blades aren't spinning?
I can't explain clearly right away. If necessary, please consult the following manufacturers:
Vestas, Gamesa, Suzlan, Goldwind, Accenton. . . .
