变速恒频双馈风力发电系统最大风能追踪控制策略

Based on the characteristics of wind turbine and the mathematical model of doubly-fed wind power generator, A control strategy, which doesn't depend on wind speed measurement to achieve the maximum wind power tracking of doubly-fed wind power generator system, has been put forward. In this strategy, based on the vector control technology of stator flux oriented, The decoupling control for active power and reactive power of doubly-fed wind power generator has been realized; Further more, By controlling the output active power of the generator, the optimal tip speed ratio and the optimal speed can be indirectly got, Then the maximum wind power tracking control can be realized. Finally, The simulation analysis based on the matlab environment, which confirm the validity of the theoretical analysis and the effectiveness of the control strategy.
