In view of the problems of poor stability and low energy recovery of the traditional wind power device,a new type of wind power device is installed in the wind power device. The new type of wind power device layout scheme is set up,and the transmission layout scheme theoretical model is completed. Finally,in the end,the performance parameters of the wind power device are compared and analyzed through the test method.The research result shows that,after the installation of the improved CVT mechanism,the energy conversion efficiency of the wind power device is improved,and the connecting shaft torque magnitude and change range of the blade and gearbox is reduced. The improved CVT mechanism can improve the performance parameters of the wind power device,and the new layout scheme is feasible.
