ウィンドファーム内の複雑地形が風車出力に及ぼす影響の解明

抄録

In Japan, wind farms are often constructed on a complex terrain. However, the wind that flows into the wind turbine on the complex terrain is complicated. In this paper, the influence of the terrain on the wind turbine power output was considered from the wind turbine measurement data and the wind condition analysis using numerical analysis. From the measured data, the wind turbine power output changes depending on the wind direction, which turbulence intensity changes even if the average wind speed is almost same. From the numerical analysis results, the wind characteristics change due to the influence of the terrain configuration depending on the wind direction. As the results, it is considered that the wind turbine power output is affected by wind characteristics due to complex terrain.
