A power curve shows how much energy a wind generator can produce at different wind speeds. When you combine a power curve with historical wind data you can determine how much total energy the wind generator would have produced during the period that the wind data spans.
We provide sample power curves of 14 wind generators, ranging from 3 kW to 3 MW or you can create your own power curve. Here is a sample power curve showing data for a large Vestas wind generator:
The most likely source of power curve data will be from the manufacturer of the wind generator you are interested in. You can also modify the samples provided or input your own curve with direct data entry.
The Red sections of line are wind speeds that don't produce any significant energy and Green section winds give the most energy. The green wind speed range is where the wind generator designer should put most of his efforts in optimizing the design. The green section wind speeds could be termed the 'sweet spot' wind range of the generator. This is a very unique and helpful data point for a design engineer. The sweet spot winds are unique with respect to the historical winds at the site chosen.

Do you have an interest in the bottom line numbers of how much power can be obtained from some new hi-tech wind generator at a particular location, and how much money will it cost to do this?
WindMapperPro is a program that helps you predict these numbers.
