Wind distribution , histograms

For each wind speed value (v) from the cut-in (ci) to the cut-out (co) phase of the WTG, the product of its corresponding power output (Pv) multiplied by the time Hv (in hours) during which value v appears in a year is calculated. The sum of these products gives the annual energy production (WEY). Wind speed values are referred to the hub height of the turbine. The power output values, which compose the power curve of a WTG, are provided by the turbine manufacturer. Hv values are calculated from the annual distribution (or the histogram) of the wind speed values.

Histograms show the percentage of total sample per division. For the salt aerosol histogram, the first division indicates concentration values up to In (0,47) (i,e, 0-1,6 pg/nP), the second division encompasses In (0,46) to In (0,94) (i,e, l,6-2,6 gg/m ), etc. The wind-speed distribution is divided into linear intervals of 1,7 m/s each.
