DESIGN AND IMPLEMENTATION OF CONTROL STRATEGIES FOR SMALL-SIGNAL STABILITY IN DOUBLY FED INDUCTION GENERATOR BASED WIND TURBINES USING MATLAB SIMULINK

A majority of the wind turbines in use today's variable speed energy systems are double fed induction generators. We went over the goals and methods used in onshore horizontal axis wind energy turbine control. Design and implementation of control the model for the simulation and the analysis of a double-fed induction generator. Among the various technologies available for wind energy conversion the DFIG is one of the preferred solution because it offers the advantage of reduced mechanical stress and optimized power capture to variable speed operation. To facilitate the electrical production control, the separated control of active and reactive powers of such as machine is considered. The results of simulations realized under the MATLAB /Simulink software are analyzed and interpreted.
