wind energy generation brushless doubly-fed wind turbine synchronous coordinates control connected to grid variable speed constant frequency
According to the characteristics of components of variable-speed constant-frequency(VSCF) wind power generator and using rotor d-q model as a start point,a mathematical model is deduced for brushless doubly-fed machine(BDFM) based on synchronous reference frame.A total model of VSCF brushless doubly-fed wind power generator is established.According to the characteristics of BDFM,a new type of control for brushless doubly-fed variable speed constant frequency(VSCF) wind power generation system connected to grid is developed.The doubly-fed control is adopted in this system,the pulse width modulation current-tracing control is used in the inner ring,and the voltage compensation is avoided.Simulation results verify the availability and validity of the proposed control strategy.
