We have observed the two wind turbines which built in two areas with different wind conditions. And we have investigated the wind turbine performance in various flows with dynamic wind direction fluctuations and different turbulent intensities and scales with wind tunnel. As a result, the power outputs of the wind turbine in turbulent flows with large fluctuation components shows higher values compared to those without large fluctuation components. In addition, the power outputs of the wind turbine in dynamic wind direction fluctuation flows show a lower value than those in static wind direction fluctuation flows and the larger an angular amplitude is, the more the power outputs of wind turbine decrease same as static conditions. However, we show that the period of angular vibration has little relation to the power outputs of wind turbine.
