中文摘要	Positioning sensors for doubly fed induction wind power generators often experience faults resulting in excess cue maintenance. Thus, a positioning sensor-less control method was developed for doubly fed induction wind power generators using the stator flux linkage vector position of various coordinates to estimate the rotor position and speed. The stator flux linkage vector with a stator stationary coordinate can be calculated by measuring the stator voltage. The stator flux linkage vector in the rotor coordinate system can be obtained from the reconstructed rotor voltage and the rotor current. The method is simpler than existing positioning sensor-less methods and only needs to measure the stator voltage and rotor current as feedback without needing stator current information. Tests show that the method gives very accurate observations of the rotor position and speed. The good dynamics and steady state performance make it suitable for variable speed constant frequency doubly fed induction generators.
