Effect of Atmospheric Stability on Wind Resource Assessment. A comparative analysis of power law, log law and Deaves and Harris model

      Аннотация: Accurate measurement of wind resource is necessary to project a wind farm. The earlier method uses cup anemometer and wind vane to measure the wind velocity and direction. Due to the advancement of wind power technology attention of researchers had turned to increase the hub height. To measure the wind data at more than 100 m height by using conventional method through met mast is now becoming the costly and time-consuming process. To observe accurate wind climate from the available met mast measured wind data at different heights an accurate wind shear model is necessary. Since WAsP and windPRO is software package which provide the better representation of wind profile over homogenous terrain only. Though, a separate module named as WAsP CFD has been added in both of the software to predict correct wind resource in complex terrain also.
