Abstract

As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. Doubly fed induction generator (DFIG) is currently employed as one of the most common topologies for wind turbine generators (WTGs). This generator operates as synchronous/ asynchronous hybrid generators. Therefore, it is necessary for power engineers to understand the characteristics of the DFIG better. This paper presents an analytical method for analysis of large-disturbance stability of DFIG. The proposed method 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 specify the effective parameters on the large-disturbance stability of DFIG, too. By using this method, one can reduce the simulation efforts necessary to assess the large-disturbance stability of DFIG.
