摘要：In the paper, double-fed induction generator (DFIG) and asynchronous power grid are taken as the research object, and the adaptability of DFIG to grid frequency is studied. The mechanism of the influence of frequency change on DFIG is revealed. It is suggested that proper settings of frequency converter protection and PLL parameters can ensure that the frequency change of power grid has little effect on DFIG. In Matlab / Simulink, the simulation of the wind turbine operating in the frequency change is realized, and the simulation results verify the correctness of the theoretical analysis.
