Active and Reactive Power Control of Doubly Fed-Induction Generator Based on Variable Speed Wind Power Generation
Abstract
This paper deals with the control of Doubly Fed Induction Generator (DFIG) in wind energy conversion system (WECS), to regulate the real and reactive power exchanged with the grid. The control architecture consists of two pulse width modulation converters allowing the generator to work in both sub-synchronous and super-synchronous mode. The real power is controlled by the energy maximization strategy, while the reactive power is controlled to operate the system under the unity power factor. The dynamic behavior of DFIG and its control are modelled based on the stator flux orientation (SFO) strategy. The control algorithm design based on anti-windup integration is developed in Matlab-Simulink.
