| Summary: | 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. |
