Research on Electrical Power System with Analysis of Fault Operation State Magnetic Field about DFIG in Wind Power

Abstract:

Doubly-fed Induction Generator (DFIG) is an important equipment in electrical power system. Operation state of DFIG is complex: it works at subsynchronism, synchronization and hypersynchrony state. Electromagnetic field is various. There is winding on stator and rotor, it’s more possible for fault to happen. Text discuss structure of DFIG, finite element method (FEM) model including stator rotor and air-gap is created, typical magnetic field is calculated including normal operation state, turn-to-turn and single-phase short-circuit happened, result is analysed, distribution discipline of multiple magnetic field is obtained. It provide the evidence to early failure prediction, basic data to develop and design high-capacity generator, optimize structure and magnetic field analysis of DFIG.
