| Abstract: |
| The scheme of six-phase PMSG（Permanent Magnet Synchronous Generator） combined with double parallel PWM converters is proposed to improve the capacity and reliability of directly-driven wind power system. The process of optimal wind energy tracking is analyzed based on the output characteristic of wind generator and an integrated control scheme combining the optimal tip-speed method and the hill -climbing method is proposed based on the comparison between these two. The mathematical model of six-phase PMSG is analyzed and its vector control strategy is given based on the proposed scheme. The simulation model of six-phase motor and wind power converter is developed with Matlab／Simulink and the process of optimal wind energy tracking for wind speed sudden change is simulated，which verifies the feasibility of the proposed strategy. |
