STATCOM for enhancement of voltage stability of a DFIG driven wind turbine

摘要

Wind farms are introduced in larger and larger quantities in power systems all over the world. Hence, it becomes more and more vital to be able to perform power system studies, including wind farm behavior, and it demands modeling of wind farms. This paper deals with the implementation of FACTS controller called static synchronous compensator STATCOM to improve the performance of the grid connected wind farms. The essential feature of the STATCOM is that it has the ability to absorb or inject fastly the reactive power with power grid. Therefore the voltage regulation of the power grid with STATCOM FACTS device is achieved. Moreover restoring the system stability after severe disturbance is achieved by using the STATCOM. to validate the usage of STATCOM a simulated model is designed when subjected to sudden load variation. The results prove the effectiveness of the controller in restoring the system stability.
