The paper deals with the dynamic simulation of wound rotor induction machines in an object oriented environment. In object oriented simulation every part of the drive system communicates by "physical" interfaces. An object oriented model for a wound rotor machine e.g. for wind turbines is presented. All magnetic couplings are modeled on basic DYMOLA elements and allow the calculation of asymmetrical effects like winding faults, asymmetric phases etc. The model is designed in the natural reference frame with three phases in the stator and three phases in the rotor. Thereby all values like currents, voltages etc. are directly accessible.
