Unbalanced Grid

This paper uses dynamic equivalent circuits to study the impact of the unbalanced grid voltage on a Doubly Fed Induction Generator (DFIG) and draws the curves between the voltage unbalance factor (VUF) and the output characteristics of DFIG. A mathematical model of the grid and rotor side converters (GSC and RSC, respectively) is given in the stationary αβ reference frame under unbalanced network voltage conditions, which could be used in the coordinated control of the GSC and RSC. Finally, simulation studies on a 1.5MW DFIG can verify the feasibility of the proposed coordinated control strategy which can be used to improve the performance and stability of the whole wind power generation system.
