Abstract EN
In order to improve the performance of a doubly fed induction generator (DFIG) system, we put forward a high performance nonlinear passivity-based control (PBC) method on DFIG.
Firstly, we build a PBC mathematical model for DFIG.
We design the passive controller for the inner loop in the control system based on passivity theory.
Then we calculate the rotor’s control voltages which are modulated afterwards to pulse to control the rotor side converter.
The maximal wind energy capture is effectively realized.
The rotor speed and DFIG currents fast track their expected values.
The independent regulation of the stator active power and reactive power is achieved.
Finally we perform simulations to verify the effectiveness of the proposed method.
Furthermore, we employ the Wigner-Ville distribution (WVD) and continuous wavelet transform (CWT) as two time-frequency representation methods to indicate that the proposed method in the paper performs well from the perspective of energy distribution in time and frequency domain.
