Popis:	The paper presents the calculationresults of DFIGs in unbalanced steady-state conditions. The formulated 2D field-circuit model additionally takes into account a nonlinearity of magnetic core and a skewed rotor slots. Among others a short circuit in a part of stator phase winding was simulated and analysed. The spectra of symmetrical components of the currents show the frequency components characteristic for the introduced faults. In particular the current third harmonics resulting from magnetic core nonlinearity have been described.
