| Abstract: | Stator interturn short circuit is a frequent fault in the operation process of doubly-fed induction generator.In the paper,law of the magnetic properties after occurrence of stator interturn short circuit fault is analyzed firstly.Then,multi-loop mathematical model is utilized for simulating and calculating interturn short circuit faults under various circumstances. The simulation results are studied deeply.The rotor-side current and stator-side current are analyzed through frequency spectrum.Response measures of generator stator interturn short circuit is formulated. |
