Dynamic Model of DFIG Under Grid Faults

This chapter analyzes the dynamic model of doubly fed induction generator (DFIG) under grid fault, including the model under voltage dips, during voltage recoveries, and under recurring grid faults. The dynamic model of a DFIG under voltage dips with three operation conditions—with rotor open circuit, with normal vector control, and with the rotor‐side crowbar are investigated. Both symmetrical grid fault and asymmetrical grid fault are included. For the dynamic model of the DFIG during voltage recovery and under recurring grid faults, the analysis is based on common fault ride‐through strategies of the DFIG, that is, using rotor crowbar under voltage dips but normal control method under voltage recoveries. For DFIG under recurring grid faults, the influences of the recurring fault parameters on the performance of DFIG are analyzed, which includes the voltage dip level and the grid fault angle of the first voltage dip, as well as the duration between two faults.
