Aiming at the influence of frequency converter on wind power system

a hybrid drive system is designed and can be used for wind turbine outputting constant frequency.The hybrid drive system includes a differential gearbox and a motor.The differential gearbox can output constant speed with variable input speed on condition that the motor is under real-time speed regulation.The FAST model of wind rotor

Solidworks model of the differential gearbox joint to Simulink model of the motor are built.By using ANSYS

the modal analysis of differential gearbox is carried out

and the result shows that the resonance wouldn’t occur under the low frequency input from wind rotor.The effectiveness of the drive system is verified through the results of the joint simulation.
