Abstract

In this paper, a nonlinear dq model is proposed for transient simulations of a salient-pole wound-rotor synchronous machine. Despite the nonlinearity between the flux linkage and the current, it is shown, thanks to a validation based on finite element simulations, that the new model is efficient for saturated transient state of the machine. This method allows obtaining more accurate results than classical linear dq model based on equivalent circuits or inductance matrices. This model is also more convenient than the linear dq model because it is more closely related to a physical model of the machine. Finally, it is far easier and faster to use than the finite element model in simulation and control.
