Abstract
As the number of installed wind turbines has increased, location suitable for wind power generation has been reduced. Then complex terrains like the mountainous regions are sometimes selected for the wind farm. In this case, the wind flow variation in the speed and direction will be severe by the complex terrain profile. So, we have conducted a wind speed measurement at actual wind power plant in Nagashima Island of Japan's Kagoshima Prefecture. In this paper, we conducted a CFD analysis of the same area with two sub-grid model of LES and compared the wind speed distribution with the measured results.
