Implementation of STATCOM in a Doubly Fed Induction Machine Based Wind Park

Abstract

Voltage stability is crucial for keeping doubly fed induction generator-equipped wind farms operating without interruption during grid outages. This research studies the implementation of a shunt-connected static compensator to ensure the continual operation of a DFIG-equipped turbine tied to the ac power network during grid fluctuations. The control schemes of the rotor-side converter and grid-side converter of the DFIG, as well as that of the STATCOM with and without fractional order proportional integral, are appropriately designed and integrated. The network system is simulated in MATLAB/SIMULINK. The outcomes demonstrate enhances transient voltage and frequency stability, active and reactive power controls, by implementing the proposed STATCOM control with a wind park for continual operations during grid disturbances.
