Nowadays, there is a tendency to increase the capacity of wind turbines, multilevel converter is a realistic alternative in such high power applications. As the wind power penetration continues to increase, grid codes have been revised to require wind farms to operate as conventional power plants. This paper proposes a reconfiguration scheme of control strategies for doubly fed induction generator...
Nowadays, there is a tendency to increase the power of wind turbines. Multilevel converter is a realistic alternative in such high power applications. As the most widely used variably speed wind turbine, doubly fed induction generators (DFIG) are very sensitive to grid disturbances. Moreover, grid codes have been revised to require wind turbines to provide Low Voltage Ride-Through (LVRT) ability....
Nowadays, the most widely used variable speed wind turbine type for unites above 1MW is doubly fed induction generator (DFIG). Because of the relative small rating of the power converters, wind turbines based on the DFIG are very sensitive to grid disturbances, especially to voltage dips during grid faults. In this paper, two control strategies of the stator flux, including a synchronous approach...
This paper presents a general modeling and an experimental validation of a doubly fed induction generator (DFIG) based wind conversion system (WCS). The wind conversion system has been briefly presented. Then, the d q control of the grid side converter (GSC) has been detailed theoretically. Moreover, the decoupled active and reactive powers control of the DFIG has been presented. The last is carried...
Nowadays, the most widely used variable speed machine for wind turbine above 1 MW is the doubly fed induction generator (DFIG). As the wind power penetration continues to increase, wind turbines are required to provide Low Voltage Ride-Through (LVRT) capability. Crowbars are commonly used to protect the power converters during voltage dips. Its main drawback is that the DFIG absorbs reactive power...
Nowadays, the wind market is dominated by doubly fed induction generator (DFIG) based wind turbines. However, they are very sensitive to grid faults due to the small rated power converters and direct connection to the grid. In order to improve its Low Voltage Ride-Through (LVRT) capability, this paper proposes a modified vector control strategy of the DFIG by considering the dynamics of stator flux...
Nowadays, the most widely used variable speed wind turbine type for units above 1 MW is doubly fed induction generator (DFIG). As the wind power penetration continues to increase, wind turbines are required to remain connected during grid faults to ride-through the faults. This paper gives a control oriented modeling of DFIG wind turbines by using causal ordering graph (COG). The control system consists...
