Zusammenfassung: | The doubly fed induction generator (DFIG) is an important component of wind turbine systems. It is necessary to identify incipient faults quickly. This paper proposes a complete simulation model of DFIG in wind turbine about inter-turn short circuit fault at stator windings, which is based on multi-circuit theory. A detail analysis about simulation results is presented, especially about short circuit current. By analysis, the apparent 150 Hz, 450 Hz and current phase angle difference are taken as fault features and the fault phase also can be detected by phase angle difference. Both simulated results and experimental results of emulated inter-turn short circuit fault by paralleling a resistance with phase A are carried out. They verify the preceding analysis results. Moreover, their coincidence certificates this model is good and simulation results of inter-turn short circuit fault are correct. |
