Transient Analysis of Doubly Fed Power Induction Generator Using Coupled Field-Circuit Model

The paper presents the transient analysis of a 1.7 MVA wind-power doubly fed induction generator (DFIG) connected to the network and controlled by modified direct torque control during power system disturbances. The finite element model of DFIG is coupled with circuit models of frequency converter, transformer, network and control part in Matlab-Simulink. The transient currents and electromagnetic torque obtained from DFIG finite element model are compared with the simulation results obtained by means of an equivalent circuit-based analytical model with constant lumped parameters.
