Abstract: The development of wind energy systems and advances in power electronics, have enabled efficient future for wind energy. Our simulation study carried out at Chennai, India during last year compares three control schemes used in wind energy systems. Three methods widely used control schemes for wind energy systems are: Pitch control, Rotor Resistance control and Vector control of double fed induction generators. Their effectiveness in controlling the fluctuations in the output power occurring due to speed variations have been investigated. The mathematical model built in SIMULINK to simulate the systems is described. The control system design for the power control mathematical model is discussed and the report concludes with an analysis of the simulation results comparing the three control techniques.
