Reduced order model based state feedback control of Doubly Fed Induction Generators

摘要

A state feedback control strategy for Doubly Fed Induction Generator (DFIGs) is investigated. Both the rotor side converter and grid side converter control of DFIG has been designed using the proposed state feedback control technique. A comparison between the traditional PI based vector control (VC) of DFIG with the proposed form of control has also been presented. It has been shown that this methodology helps in easier controller design for DFIG, exhibits competitive performance in terms of low interaction between power and voltage control and provides better system damping. The simulation results for a system connected to a grid through a transmission line have been presented and the capabilities of the proposed controller are discussed.
