In the normal operation of the double-fed induction wind generator, the stator winding interturn short circuit is one of the most common fault, using the finite element method (fem) analysis of doubly-fed induction generator, and with the aid of finite element analysis software ANSOFT Maxwell 2D module to established simulation model of doubly-fed induction generator, Through analysis and simulation the eddy current loss in the process of motor running, get the method to minimize eddy current loss.The normal operation of motor and malfunctions under different degrees are simulated. The failure conditions are analyzed as well. Severe breakdowns can directly affect the electromagnetic field and magnetic flux of a fault phase or fault phases, which can no longer make motor’s magnetic field and its magnetic flux distribution symmetrical.
