Problems solved by technology

[0005] In the above-mentioned CN102749853A, the essence is to realize the physical towing platform of the low-power prototype, which cannot be used as a mirror image model of a large-scale wind turbine

The aerodynamic model of the wind turbine is directly related to most other models. In this invention, the aerodynamic model is realized by dSPACE, which is not as accurate as the professional software Bladed, and there are no mechanical part models such as flexible towers and flexible blades.
