Description: Wind Power Wind Power Fundamentals:- Origin of Wind:Wind – Atmospheric air in motion Energy source Solar radiation differentially absorbed by earth surface converted through convective processes due to temperature differences to air motion. Spatial Scales:- Planetary-scale: global circulation. Synoptic scale: weather systems.
Meso-scale: Local topographic or thermally induced circulations. Micro-scale: urban topography. Efficiency in Extracting Wind Power:- Betz Limit & Power Coefficient: Power Coefficient, Cp, is the ratio of power extracted by the turbine to the total contained in the wind resource Cp = P to the total contained in the wind resource Cp=PT/PW.
