This paper develops the full order models of doubly-fed induction generator (DFIG) with series grid-side converter aiming to derive its stability region on the PQ-plane. The stability region on the PQ-plane is given and reveals that the DFIG with series grid-side converter is a feasible solution for wind turbines connected to unbalanced voltage grids. The configuration of DFIG's with series grid side...
This paper proposes and describes the controllers for doubly-fed induction generators (DFIG) with series grid side converter. It is demonstrated that with series grid side converter instead of a conventional shunt grid side converter the DFIG stator voltage can be kept balanced even under heavy unbalance grid voltages. Therefore, in this way it is avoided the undesired effects such as torque oscillations...
Increasing penetration of the large wind farm in the system has forced the power system policy makers to develop new electricity grid codes which are required for the wind power generator to fulfill the same requirements as conventional power plants. In this paper, a series connected grid side converters with conventional doubly-fed induction generator (DFIG) scheme is explored to suit the grid code...
With the increased penetration of wind power in the system having new electricity grid code, it is required for the wind power generator to fulfill the same requirements as conventional power plants. In this paper, series and parallel connected grid side converters with conventional doubly fed induction generator (DFIG) scheme is explored to suit the Grid Code Requirements (GCRs) during static and...
