英文摘要	In this paper, taking a 3.6 MW horizontal axis wind turbine as the research object, adopting the field experimental method, and using remote sensing test technology, the influence of turbulence integral scale of atmospheric boundary layer on horizontal axis wind turbine power fluctuation is studied. The results show that in the front of the rotor, the wind speed at the distance of the rotor radius is about 5% lower than that at 1.5 times the rotor diameter, while the turbulence increases by nearly 1.5 times at the height of the hub. At the same time, the power spectrum characteristics of wind turbine output power based on SCADA data exhibited three distinctive regions, which are large-scale meteorological phenomenon affected region, turbulence characteristics and power fluctuation coupling region and affecting region of small-scale turbulent pulsation, respectively. The power spectrum of the turbulence characteristic and the power fluctuation coupling region exhibits a slope of -2 and -5/3-4, and three peaks caused by the rotation of the rotor appear near the affecting region of small-scale turbulent pulsation. Two power-law relations of Φp/Φu-f-1 and Φp/Φu-f-4 appear respectively when the frequency is less or greater than 0.064 Hz. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
