Özet:

The integration ratio of wind farms to the grid is increased tremendously derived by the need for cleaner and renewable energy. However, the stability of the grid is a major concern due to large wind and other renewable resource-based power plants. Thus, wind turbine generators must adhere to the regulations of other conventional forms of generation. To boost stability, especially voltage-based, Flexible AC Transmission Systems such as Static Var Compensators (SVC) or Static Synchronous Compensator (STATCOM) are put in the vicinity of the wind farm's connection point to the grid. This study is intended to model and simulate dynamically a wind farm using the Doubly Fed Induction Generator (DFIG) turbine type and STATCOM under faulty conditions. The model is implemented inside the DigSILENT Power Factory simulation tool. The results show that STATCOM can improve the voltage stability of wind farms at the point of connection to the grid.
