| Abstract: | In order to understand the scale relationship between the power output and the incoming turbulence of large wind turbines in the plateau environment, taking the large-scale horizontal axis wind turbine in the Qinghai-Tibet Plateau as the research object, based on the advanced LiDAR technology and through the field experiment method, the scale coupling relationship between the inflow and the output power of the wind turbine for one hour of continuous operation under specific wind speed was studied and analyzed. The results show that the ratio of turbulence scale time lag to convection time in the mesoscale range is close to the ratio of power delay time to convection time; the intermittent characteristics of inflow turbulence are transmitted to the wind turbine rotor and amplified by the increase of turbulence intensity and wind shear exponent. And Turbulence in high frequency has no obvious effect on power. It can provide reference for the study of wind turbine structural response in plateau area and other special conditions. |
