Abstract :
The impact of Static Synchronous Compensator (STATCOM) to the small signal stability of the integration of a large wind farm is studied. First, STATCOM controller with Supplementary Damping Control System (SDCS) is proposed, to enhance damping of power system. And the simulation model is designed in DIgSILENT /PowerFactory. Second, a large scale wind farm equipped with Doubly Fed Induction Generator (DFIG) is established, where a STATCOM is utilized to improve the small signal stability. Finally, it can be concluded from the simulated results that the STATCOM with SDCS is very effective to stabilize the studied system under disturbance conditions.
