International Journal of Computer Applications (0975 – 8887) Volume 67–No.1 6, April 2013 Active and Reactive Power Control of a DFIG for Variable Speed Wind Energy Conversion using a New Controller N.Hamdi, A .Bouzid, Electrical Laboratory of Constantine “LEC”, Electrical Laboratory of Constantine “LEC”, Department of Electrical Engineering, University Department of Electrical Engineering, University Constantine 1, 25010 Constantine, ALGERIA, Constantine 1, 25000 Constantine, ALGERIA, ABSTRACT The objective of this work lies in the modeling, simulation This paper presents a vector control direct (FOC) of double and decoupled control of active and reactive powers for a fed induction generator intended to control the generated doubly- fed induction generator using the standard relay stator powers. This device is intended to be implemented in a controllers and to make a comparison with PI controllers. variable-speed wind-energy conversion system connected to the grid. In order to control the active and reactive power The reminder of the paper is organized as followed : In section exchanged between the machine stator and the grid, the rotor II, the DFIG model in an arbitrary reference-frame is is fed by a bi-directional converter. The DFIG is controlled
