Feedback Linearization control based power control of grid connected DFIG with grid synchronization

This paper presents implementation of Feedback Linearization based control (FBLC) for the smooth connection of the doubly fed induction generator to the power grid and for the power control of the grid connected doubly fed induction generator. The induced stator voltage vector of the DFIG is synchronized with the grid voltage irrespective of the accuracy of signal from position encoder. Computer simulation results for the test set up show excellent response in starting up the generator on the fly and also in achieving decoupled power control thereby validating the effectiveness of the proposed control approach.
