How to estimate the energy of wind turbine?
how do i estimate the annual energy output of a 5kw wind turbine in an area which has a average wind speed of 7.4m/s at 10m above ground level, and the rated wind speed of the turbine is 10m/s. there is no buildins around to interfear with the wind and the hub of turbine is 12m above ground level. and could you show me the formula for this sum.
It’s not quite that simple.
Wind turbines have a ‘power curve’ showing their output at various wind speeds. An ‘average’ can be based on minor variations (7.2 to 7.6 m/s) or major variations (3 to 12 m/s – OK, that averages to 7.5, but you get the point). Since the energy in wind varies with the cube (third power) of the wind speed, the amount of variation in the average is critical.
There is a calculator here: http://www.windpower.org/en/tour/wres/pow/index.htm, but I highly recommend you review the other information on the site before spending any money!
Best of luck!
