With the increase of installed capacity of wind power and the increasing proportion of wind power in the power grid, all kinds of wind turbines will have more and more prominent influence on the safety and stability of power system. Different types of wind turbines with different capacity have different effects on the stability of power grid. In this paper, PSD simulation software is used to build a power grid with wind farms in a certain area. The influence of large-scale wind turbines connected to the grid on the transient stability of the power grid is studied according to different types, different capacities of the same type and different manufacturers of the same type of wind turbines.
