Abstract: Aiming at double fed induction generator (DFIG) wind farms, this paper proposed a kind of primary frequency modulation self-adaptive combined control strategy, used the study inferential capability of neural network and drilled the fuzzy neural controller to realize the DFIG wind farm rotor kinetic energy release and reserve power additional self-adaptive coordination control and to make the DFIG wind farm be able to participate in the system frequency control so as to promote the primary frequency control ability. The simulation result shows that this control method could effectively improve the frequency control ability of wind farm system with DFIG, reduce the impact from the DFIG wind farm grid connected to regional power grids, promote regional power grids acceptance wind power capacity and accelerate efficient utilization of renewable energy sources.
Key words: double fed induction generator wind farm; self-adaptive; frequency control; rotor kinetic energy; reserve power
