New grid codes demand the wind turbine systems to ride through recurring grid faults. In this paper, the performance of the doubly Ffed induction generator (DFIG) wind turbine system under recurring symmetrical grid faults is analyzed. The mathematical model of the DFIG under recurring symmetrical grid faults is established. The analysis is based on the DFIG wind turbine system with the typical low-voltage...
Ride-through capabilities of the Doubly-Fed Induction Generator (DFIG) during grid fault have been studied a lot. However, the thermal performance of the power device during this transient period is seldom investigated. In this paper, the DFIG performance in terms of the stator flux evolution and the rotor voltage during the balanced grid fault is firstly addressed. By using the traditional demagnetizing...
