摘要：
In order to grasp the influence of continuous hilly terrain on the power characteristics of wind turbines, the NREL Phase VI wind turbine aerodynamic model was built based on CATIA software and Computational Fluid Dynamics software (Fluent). Coupled with three-dimensional continuous hilly terrain model and wind shear, the model obtains the aerodynamic characteristics analysis method of the wind turbine under continuous hill conditions. The accuracy of the aerodynamic analysis method of the wind turbine is verified by comparison with the experimental data in the atmospheric boundary layer (ABL) wind tunnel of the NREL Phase VI wind turbine. Then, andyzing the wind turbine power on the flat ground and hilly terrain, and changing the wind turbine's position relative to the hills and the shape of the hills, studying the influence of the continuous hills on the torque, thrust and power of the wind turbine, finally obtain the best location of wing turbine for continuous mountain model. Research results show that the wind turbine at the top of the second mountain has the highest power. When the wind turbine is placed hilly downstream area, the stall zone should be avoided as much as possible, and the wind turbine on the side of the mountain has higher power than that in front of and behind the mountain. © 2021, Solar Energy Periodical Office Co., Ltd.
