| Abstract: | As the installed wind power capacity increased,the grid code have required the wind turbines must have low voltage ride-through(LVRT) capability,a voltage sag generator(VSG) is the important equipment for wind tu-bines to evaluate the operation capacity of LVRT.Based on the analysis of the types of voltage sags that maybe occur at the wind turbines terminal,a novel control strategy adopted proportional integral resonant(PIR) for VSG is pro-posed to control the positive and negative sequence component of the... |
