This paper is aimed to describe a wind energy conversion system, including a doubly fed induction generator (DFIG), a bidirectional converter in the rotor circuit the DFIG is able to work as a generator in both sub-synchronous and super-synchronous modes. The topology of a DFIG, stator is connected direct to the grid while the rotor is connected to grid with back to back converters. The wind turbine...
A Backstepping adaptive control is proposed in this paper in order to raise the extraction of power in variable speed wind turbine in region two. This wind turbine is modeled by two masses drive-train with generator torque control. By using the model obtained, an algorithm of adaptive Backstepping has been designed to achieve the global asymptotic generator with speed tracking and to estimate the...
This article discusses the modeling and control wind energy conversion system WECS, equipped by a double fed asynchronous generator, which use the topology that stator is connected direct to the grid while the rotor is connected to grid through a back-to-back converter. The control strategy is applied to control active and reactive powers of the rotor side converter RSC with linear PI controller....
This paper presents the nonlinear control strategy for high performance doubly fed induction generator driven by wind turbine. In the DFIG topology the stator is connected direct to the grid while the rotor is connected to a back-to-back converter. A simple and general space vector PWM algorithm is proposed. First, we propose a modeling of wind turbine and DFIG in the dq reference frame. Next, a field...
