摘要	Comparing the average wind speed profiles obtained from the Great Plains Low-Level Jet (GP_LLJ) spectral model and the low-level jet (LLJ) engineering model based on the plane wall jet principle, the parameters in the LLJ engineering model were determined. On this basis, the LLJ fluctuating wind fields with different LLJ heights were simulated based on the Von Karman spectra model and LLJ engineering model, and were used as the input condition of FAST open source code to calculate and analyze the aerodynamic loads of the horizontal axis wind turbine. The results show that when the LLJ intensity is constant and the LLJ height increases from the bottom-tip to top-tip of the rotor, the RMS of the rotor aerodynamic load coefficients, including ones of thrust, torque, lateral force, longitudinal force, yaw moment and tilt moment, shows obvious change, and the respective maximum is increased by 12.9%, 75.6%, 73.4%, 27.7%, 99.9% and 98.5%, compared with their minimum. The peak frequencies of the power spectrum of the rotor torque and thrust are related to the integral multiples of the blade passing frequency. © 2019 Chin. Soc. for Elec. Eng.
