The wind-thermal mixed power transmission is a feasible solution to Chinese power issues. However, the transient stability of transmission type is quite different from traditional grid. In this paper, an average model for DFIG is built to describe the DFIG behavior as well as reduce calculation time. The angle transient stability characteristics are studied in the scenarios with different wind power penetration and constant total power capacity. The results indicate that DFIG has positive effect to the synchronous generator stability.
