Abstract: 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.

Key words: pulse coherent Doppler lidar, wind turbine, wake effect
