The major concern in smooth operation of the DFIG wind turbine technology is control of wind turbine generators to ensure stable operation and to avoid sympathetic trips during system imbalances. The operation of the DFIG under different disturbances is analyzed using MATLAB Simulink and the built-in model developed by DIgSILENT in their PowerFactory software. The specific imbalances studied ar...

This paper focuses on the small-signal stability of power system integrated with DFIG-based wind farm. The model of DFIG for small-signal stability analysis has built; the 3-generator 9-bus WECC test system is modified to investigate the impacts of large scale integration of wind power on power system small-signal stability. Different oscillatory modes are obtained with their eigenvalue, freque...

-In this paper we present a new control structure to extract the maximum power of a wind energy conversion system based on the double fed induction generator (DFIG). The proposed algorithm combines the nonlinear Backstepping approach and the field orientation scheme applied to control the rotor side converter (RSC) and the grid side converter (GSC) of the DFIG. The proposed strategy is asymptot...

Doubly fed induction generator (DFIG) wind power generation system is widely used in farm all over the world. Reactive can be generated both grid-side converter and generator-side of DFIG. In this paper, working principle control method DFIG are introduced, reactive limit derived, finally regulation simulated Simulink.

The wind turbine technology is now a developed technology. Modern wind technology incorporates each aspect of grid integration, stability and power quality issues in the arena of reliable power production to user end or utility. The paper provides cumulative modernization of wind turbine technology through literature survey of wind turbine configurations followed by discussion of different cont...

Abstract—This paper deals with a variable speed device to produce electrical energy on a power network, based on a doubly-fed induction generator (DFIG) used in wind energy conversion systems. In the first place, we developed a model of the doubly fed induction machine. In order to control the power flowing between the stator of the DFIG and the power network, a control law is synthesized using...

In renewable power generation doubly fed induction generators (DFIG) are used, in which the stator of the generator is directly connected to mains, while the converter for the rotor is rated only for slip power. Due to the interaction of rotor and stator windings in a DFIG, the high-frequency harmonics caused by the pulsed output of rotor power converters are transmitted into the stator current...

In this paper, we present a nonlinear robust control of active and reactive power by the use the PI regulators control (FOC) a Double-Fed Asynchronous Generator (DFIG) system incorporated in a windturbine. The power transfer between the stator and the network grid is carried out by acting on the rotor via a bidirectional signal converter. Initially, a control strategy of the MPPT-DFIG is presen...

Considering the importance of perturbations during short circuit (SC) in power conversion devices, this study designed to find out the efficacy of symmetrical short circuit (SSC) of the synchronous generator (SG) and doubly fed induction generators (DFIG). Both wind power systems were separately built (Park’s model) and simulated. Simulation results showed that the DFIG is more efficient, fault...
