The wind turbine wake can reduce the wind energy conversion efficiency, increase mechanical stress damage and reduce the life span of wind turbine. In order to study the characteristics of turbine wake in Xinjiang, China, the observation of wind based on pulse Doppler lidar was conducted in November 2015. The characteristics of wind turbine wake in Xinjiang were obtained, including the velocity deficit, wake width, wake length and average value of wake, variation of wake with time and relationship between wake and wind speed. The final results show that the velocity deficit, the wake width and the wake length are related to ambient wind velocity and wind turbulence intensity.
