Wind Power Density Estimation using Meteorological Tower Data

The amount of power in the wind is very dependent on the speed of the wind. Because the power in the wind is proportional to the cube of the wind speed, small differences in the wind speed make a big difference in the power you can make from it. A 10% difference in speed makes about a 33% change in power. This gives rise to the primary reason for wind resource assessment. In order to more accurately predict the potential benefits of a wind power installation, wind speeds and other characteristics of a site’s wind regime must be accurately understood. This gives rise to the primary reason for wind resource assessment. In order to more accurately predict the potential benefits of a wind power installation, wind speeds and other characteristics of a site’s wind regime must be accurately understood. In this paper the important aspects of wind resource assessment for a period of three years from 2010-2012 will be studied for a 50 meter instrumented meteorological tower located at Sathyabama University, Chennai.
