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...

This paper presents dynamic modeling and simulation of Brushless Doubly Fed Induction Generator (BDFIG) as an alternative for variable speed wind power applications. The mathematic models of active and reactive power for BDFIG have been developed. The power control systems of a 75 kVA generator and wind turbine were simulated in Matlab/Simulink/SymPower Systems. The generator’s control system i...

Using the FACTS controllers, such as static synchronous compensator (STATCOM), as it provides continuous reactive power, in the grid including wind turbine (WT) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. In this paper, in order to contr...

Wind energy conversions are growing rapidly as a renewable source. A new method of interconnected wind power production that utilizes doubly fed induction generator coupled to quality Analyst matrix converter is described in this study. The aims project include Doubly-fed modeling and simulation rotor current controlled via space vector modulated converter. This strategy aimed directly at the c...

This paper presents a comparison between a fuzzy logic controller and a conventional IP controller used for speed control with a direct stator flux orientation control of a doubly fed induction motor. The effectiveness of the proposed control strategy is evaluated under different operating conditions such as of reference speed and for load torque step changes at nominal parameters and in the pr...

Abstruct In this paper field-oriented control of a doubly-fed wound rotor induction machine without shaft position sensors is presented. The stator is directly connected to the constant frequency three phase grid and the rotor currents are appropriately controlled to vary the slip power thereby enabling variable speed constant frequency operation. Instead of using dynamic angle controllers for ...

This paper deals with the problem of controlling doubly-fed induction machines (DFIM). A nonlinear model of the whole controlled system, including the DFIM and the associated AC/DC rectifier and DC/AC inverter, is developed within the Park coordinates. A multi-loop nonlinear controller is developed, using the backstepping design technique. The controller is formally shown to meet its objectives...
