| Abstract: | To meet the requirement for the capacity,low current harmonic level and low switching loss,direct-drive wind power generation system employed the topology which combined the permanent magnet synchronous generator(PMSG) and dual three-level PWM full-size converter.Based on d,q axis mathematical model of PMSG,in order to take full advantages of saliency effects,improve efficiency,the generator side adopts simplified space vector pulse width modulation technology combined with maximum torque per ampere control scheme.The grid side employes the dual close-loop control strategy which are the inner current-loop and the outer voltage-loop.The model of direct-drive wind power generation system is realized with the engineering software,Matlab for the case of wind speed stepping change shows the excellent dynamic performance of the model,in the same time,verifies the correctness and feasibili-ty of the control strategy. |
