Abstract: As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. The doubly fed induction generator (DFIG) is currently one of the most common topologies employed for wind turbine generators (WTGs). This generator operates as a synchronous/asynchronous hybrid generators. Therefore, it is necessary to power engineers find understand the characteristics of the DFIG better. This paper is used an analytical method for analysis of large-disturbance stability of DFIG. The proposed analysis is based on the concepts of stable and unstable electrical-mechanical equilibrium points the electrical - mechanical torque versus rotor speed and Critical fault clearance time of DFIG. The results of analysis specified the effective parameters on the large-disturbance stability of DFIG. In other words, this analysis reduces the simulation efforts necessary to assess the large-disturbance stability of DFIG.
Keywords: Wind turbine, Doubly fed induction generator (DFIG), Large-disturbance stability, Critical fault clearance time, Distributed generation , Critical rotor speed.
