Stabilization of pitch controlled wind turbine induction generator by STATCOM

This paper, presents a pitch controlled Wind Turbine Generation System (WTGS) which is used in practice now a days, to have optimum power flow and to reduce overloading of wind turbine when higher wind speeds are available. Also, a pitch control system is used for stabilization of the wind turbine at grid faults. Application of Static Synchronous Compensator (STATCOM) and static capacitor bank is presented to enhance transient performance of grid connected pitch controlled wind farm. A simple control strategy for STATCOM is adopted, where only measurement of rms voltage at induction generator (IG) terminal is needed. It is observed that STATCOM gives better performance than static capacitor bank.
