Abstract

Recently, in wind power generation, doubly-fed induction generators (DFIG) have been commonly employed, and their capacity is also increasing, making DFIG’s security and reliability more significant. Stator winding inter-turn short-circuit faults (SWITSCF) are a prevalent flaw of theirs. In this paper, a DFIG has been modeled by the finite element method (FEM) in the healthy state and in the faulty state. Several simulations have been carried out for different number of inter turn short-circuit faults (NSWITSCF) to see their effects on the DFIG performance. SWITSCF modifies the impedance, which affects the current amplitudes and phases. As a consequence, the current is asymmetric where a negative sequence component is observed. SWITSCF gives the cause of the existence of the short-circuit current that generates an additional magnetic field. This will make the magnetic circuit largely saturated. Furthermore, with the NSWITSCF increasing, these negative effects appear stronger and move away from a healthy state.
