摘　　要：结合模型参考自适应法(MRAS)和定子电压定向矢量控制的特点,提出了一种新型的基于MRAS双馈风力发电机无速度传感器矢量控制方案。这一新的方案,在理论分析、Simulink仿真的基础上通过双馈风力发电机组实验平台进行了不同转速工作方式下的实验论证,结果证明此方案具有良好的动、静态性能;能够在低速和高速的情况下准确的辨识转子位置和转速。Combined with the characteristics of the model reference adaptive method（ MRAS） and stator voltage oriented vector control,a new kind of MRAS speed sensorless vector control scheme of doubly-fed wind power generator was put forward. On the basis of theoretical analysis and the Simulink simulation,the method was tested through doubly-fed wind turbine platform under different speed. The results prove that this scheme has good dynamic and static performance,and can accurately identify the position and speed of rotor at low speed and high speed.
