Recently, as a solution to the environmental problem, wind energy that is renewable energy has attracted attentions. In wind farm, which consists of multi wind turbines in a site, a wind turbine may be operated in the wake generated by the upstream one at a certain wind direction. Because of lower wind speed and higher turbulence intensity in wake, it causes lower power output and higher load fluctuation. Therefore, the clarification of wake is important in wind farms. In this study, a field test using a horizontal axis wind turbine was performed. The wind velocity distribution in wake was observed by using ultrasonic anemometers installed vertically on a meteorological mast. The axial thrust on the rotor was measured by using a load cell attached between the nacelle and tower. The present paper shows the experimental results of the distributions of wind speed and turbulent intensity in wake and clarifies the effect of the thrust coefficient on them.
