Voltage behind Reactance Model of the Doubly Fed Induction Generator using Space Vectors

Abstract

In this paper, a method is proposed to develop the Voltage Behind Reactance (VBR) model of the doubly fed induction generator (DFIG) by applying space vectors. Two reference frames are used, one for the stator and the other for the rotor, to maintain the respective ports. This type of model is useful when simulations are to be performed using circuit analysis tools such as ATP-EMTP, Simulink, PSIM or similar. To demonstrate the validity of the VBR model of the DFIG machine, the results obtained by performing this modeling in ATPDraw and Simulink are compared with simple cases where the rotor is short-circuited, including an external impedance or applying voltage sources at different frequencies. The results obtained from the simulations demonstrate the validity of the model and the simplicity of its derivation using the space vector framework.
