excuse me! Can anyone teach me how to solve the problem below? 1.During the fault period (three-phase grounding), the PCC point voltage will be very unstable (large oscillation) 2.When the generator connect to the grid，which parameters of generator should i update

thanks~

Don't be so quick to blame the wind generator model. It may be a physical oscillation (instability of the wind generator) or it may be a numerical oscillation (associated typically with a wind generator connecting to a grid with low short-circuit ratio).

This is right. There is maybe a physical limit. At the same time, optimizing the electrical control model of wind can probably help its stability performance
