How to calculate the energy of a wind turbine?
How to calculate the energy of a wind turbine? How do I calculate output annual energy of a wind turbine on a 5 kW area that has a mean wind speed of 7.4 m / s at 10m above ground level and the nominal wind speed the turbine is 10 m / s. no buildins around interfere with the wind and the turbine shaft is 12m above the ground. and Could you show me the formula for this sum.
The turbines not so simple. Wind has a 'power curve', showing her with wind speed. An "average" may be significant variations lower (7.2 to 7.6 m / s) or major variations (3 to 12 m / s – OK, that average to 7.5, but you get the point). Since the energy in the wind varies with the cube (third power) of wind speed, the amount of variation in the average critical. There is a calculator here: http://www.windpower.org/en/tour/wres/pow / Index.htm, but I recommend that you review the information on the site before spending money! Good luck!
