摘要 | The wake characteristics of wind tower and the existing wind turbine wake model were analyzed based on the wind speed and wind direction measurement data of a wind farm in northwest China during 2015-2016. The wind field characteristics under the effect of far wake flow field, such as wind speed, turbulence intensity, turbulence integral scale, and probability density distributions, were studied in detail. The results show that the existing Jensen model and Park-Gauss model are different from the wake characteristics of the wind farm under the action of multiple wakes in practical engineering. Under the action of multi-wake superposition, when the wind speed is greater than 10 m/s,the turbulence intensity of each wind tower increases with the increase of the mean wind speed, and the turbulence intensity of the internal wind tower is more concentrated in the lower turbulence section. With the increase of the mean wind speed, the turbulence intensity of the external wind tower increases faster than that of the internal wind tower; the turbulence integral scale of the external wind tower increases slower than that of the internal wind tower, and the measured wind speed of the peripheral wind tower is more in line with the Gaussian distribution. © 2018, Editorial Department of Journal of Southeast University.
