A Novel Method for Excitation Control of DFIG Connected to the Grid on the Basis of Similar Signals from Rotor

Abstract:

This paper proposes a novel technique for the new excitation control of the doubly-fed induction generator (DFIG) on power-station which connected to the grid. That is using the similar signals from rotor of a small capacity doubly-fed induction machine (DFIM) as a base to generate the control signals for the former DFIG. Based on this method, a simple but effective controller is designed, which ensures to decouple the active and reactive power supplied to the grid by using two separate parameters Kp and Kq. The advantage of this method is that it is simple but still effective.
