The Independent Control of Reactive and Active Powers with Doubly-Fed Induction Generator for Wind Energy Conversion

Abstract

This paper present a modelling and control of doubly fed induction-generator (DFIG) used in wind energy conversion systems. To regulate the active and reactive power exchanged between the machine and the grid. A detail dynamic model of a DFIG-based wind- turbine grid-connected system is presented in the dq- synchronous reference frame by controlling the machine inverter with the algorithm of control based on vector control concept (with stator flux orientation), with a classical PI controllers: proportional–integral, .The control of our machine is simulated in MATLAB/simulink envirenement, finally the Simulations results are presented and discussed.
