摘要: The invention discloses a method for inhibiting total output harmonic current of doubly fed induction wind power system under the condition voltage grid. is related to control over series grid-side converter, parallel converter and motor-side converter. According method, PWM driving signals are generated through space vector modulation after calculations carried out. objectives that three-phase stator rotor generation free distortion, motor electromagnetic torque fluctuation grid achieved safe stable operation an electric generator ensured, degree can be greatly reduced, quality parallelly connected with DFIG improved effectively.
