| 英文摘要 |
| The robust control problem is addressed for the variable speed/constant frequency wind power generation systems equipped with doubly-fed induction generators. The wind power system is mathematically modeled by using the field-oriented vector-transformation of the stator. A rotor excitation controller is designed by utilizing nonlinear robust control technology, which realizes the robust decoupling control for the active and reactive power of the generator, and the attenuation of the external disturbance. The theoretical analysis and the simulation show that under variable wind-speed, uncertain parameters and the external disturbances, the proposed controller guarantees the wind power system to achieve the maximal absorption of wind power in the secure and stable operation, and to output the electrical power with constant frequency and constant voltage for the grids. |
