| Abstract: | A coupling analysis model of the wind turbines is obtained through establishing a random wind speed model,a aerodynamic performance model,a transmission train model and a generator model.According to the control strategy of the variable speeds wind generator,the transmission system dynamic loads are calculated and the influences upon transmission system dynamic loads based on rigid and flexible drive train are investigated,which lays a foundation for further study on dynamic characteristic and reliability of the wind power generator gear transmission system. |
