Abstract:As a new generation mode,a large amount of the integrated doubly fed induction generators (DFIG) have an effect on the dynamic behaviors of the power system.With the installed capacity of DFIG based wind power increased,this impact on the power system stability is gradually emerging.In this paper,the theoretical analysis and simulation verification for the angle stability of the synchronous generator after the DFIG connected to the grid are studied from two aspects,one is reducing the synchronous generator output and the other is replacing the generators with the equally capacity DFIG.The results demonstrate that the DFIG connected to the system is benefit for the angle stability of synchronous generators to a certain extent.
