A power system stabilizer（PSS） is added to the double-fed induction generator（DFIG） current transformer control system to suppress the low-frequency oscillation of the wind power grid connection. For the wind power grid-connected systems that used in industrial production

a DFIG is used as the wind turbine for our research

and a complete wind power grid-connected system model is established to analyze the generation process and influencing factors of low-frequency oscillation of grid-connected wind power. After the model is established

the power system stabilizer is used in the wind turbine converter control system to suppress the system ’s lowfrequency oscillation. Next

time domain numerical analysis method and eigenvalue analysis method are used to verify the suppression effect of low-frequency oscillation after adding the power system stabilizer. The results of simulation experiments show that using the power system stabilizer can effectively suppress the low-frequency oscillation of wind power grid connection and improve the stability of the grid-connected system.
