For constant ratio for traditional wind power system with low energy utilization and poor adaptation to the external environment

the metal belt CVT is introduced as a part of traditional wind power system

the eventual of a new variable ratio wind power system is established

through numerical modeling method

the model of the new variable ratio wind power systems is built

the variation law of system parameters

performance indicators before and after introduction the metal belt CVT into wind power system is studied.The results show that metal mounting system CVT wind speed changes in the external conditions

overall power coefficient

turbine power

electric power delivered

the torque transmission shaft and energy efficiency are higher than the system is not installed

since the introduction of the metal belt CVT

the drive shaft torque before the changes become smoother than the installation

which has direct implications for increased torsional fatigue life of the drive shaft.The energy efficiency of installation metal CVT wind power system wind conditions at each interval change in energy efficiency compared to not install the system is small

stable energy output.
