摘要：
Aiming at the newly-proposed wind turbines with differential speed regulation, the kinematics principles, total power flow and mechanical efficiency of the transmission system were studied. On the basis of completing the triaxial dynamics of the wind turbine transmission systems, a 1.5 MW simulation model of wind turbines with differential speed regulation was established. Afterwards, the correctness of the built simulation model was verified via experiments. Finally, the transmission performances of the proposed wind turbines were studied with the 1.5 MW simulation model. The simulation results show that the overall transmission system efficiency of the proposed wind turbines is high enough under different wind speed conditions which may be up to 0.951. The power required for speed regulation is quite small and only accounts less than 15.47% of that outputs by synchronous generator, while the maximum steady-state errors of the output speed are all less than 1.23%. The transmission performances of the proposed wind turbines are able to meet the requirements for practical applications well. © 2019, China Mechanical Engineering Magazine Office.
