Abstract:
In this paper a new double tuned PI-R based currentcontroller has been used for effectively mitigating the mostsignificant and troublesome harmonic current of grid side inDFIG system. One part is tuned at 6ωs and the other is tuned at12ωs which are responsible for mitigating 5th,7th and 11th,13thorder harmonic components respectively. Mitigation method isapplied to the rotor side converter whereby controls thefundamental and harmonic current components simultaneously,so that fundamentals are used for decoupled active and reactivepower control and harmonics for enhancing power quality. Thecontroller performance is investigated by simulation in Simulink-SimPower environement and compared to the conventional PIcontroller. The results confirm the controller prominent features,tracking ac contained refrences and mitigation capabilities.
