Abstract
In this paper, a new dynamic model of a DFIG subjected to the multiphase inter-turn short circuit fault (ITSC) is proposed. This model can quantitatively describe the faults occurring in multiple phases of the stator and rotor. What´s more, a state-space representation of this faulty model is also derived. Base on this model, an adaptive observer is developed which can provide an online diagnosis of the fault position and level by estimating the amount of the shorted turns for each phase.
