Dynamic Compensation of Real and Reactive Power in Wind Farms using STATCOM

Publication date: Available online 25 July 2016 Source:Perspectives in Science Author(s): Shahzad Ahsan, A.S. Siddiqui The dynamic stability of Squirrel Cage Induction Generators (SCIG) based wind turbines may be improved by Static Synchronous Compensator (STATCOM). At the time of starting of wind farm and during short circuit fault the voltage of bus connecting the wind farm reduces drastically (Chen, 2005). A controller for the STATCOM has been developed with its capability to coordinate between the positive and the negative sequences of the grid voltage. This paper investigates effects of Squirrel Cage Induction Generator (SCIG) in combination with a Static Synchronous Compensator (STATCOM) under normal and during fault condition (Inwai et al., 2005). The results show that the STATCOM can regulate the fast changing voltage at the point of common coupling between the wind farm and the grid in normal and during fault condition. Also it can supply the active power during the short circuit fault condition.
