The wind turbines installed in the wind farm are influenced by the wake of upstream turbine. Therefore, it is important to understand the details of the wind turbine wake. This paper shows the wind velocity distribution in wind turbine wake downstream to the three times the distance of the rotor diameter by the field measurements. The test wind turbine is a horizontal axis wind turbine with a rotor diameter of 10m, and a hub height of 13.3m. The velocity distribution was measured by 5 ultrasonic anemometers set on the vertical mast. The measurement data shows velocity deficit of the wake and the velocity recovery tendency. The velocity above hub height recovers shorter distance than that below hub height.
