Abstract
One of the chief methods used to overcome voltage dip problems in doubly fed induction generator (DFIG)-based wind turbines is low voltage ride through (LVRT) capability. In order to solve such voltage dip problems during symmetrical and asymmetrical grid faults, this study presents a novel enhanced dynamic modeling approach for LVRT in DFIG. Positive and negative sequence models, along with natural and forcing flux models were used to enhance the proposed LVRT capability strategy for a DFIG. In addition, electro-motor-force (EMF) was applied for the enhancement of the stator and rotor circuit model. The novel stator-rotor dynamic modeling was also used in boosting the transient stability operation against three phase and two phase faults. When the proposed dynamic modeling was applied, the system was stabilized within a short amount of time and the oscillations ceased.
