Voltage stability enhancement of DFIG based wind farm during fault using STATCOM

Abstract

Voltage stability is prominent thinking to keep DFIG-based windfarm during the grid disturbances. This paper inspects the employment of STATCOM to overwhelmed the voltage stability problem for DFIG based wind farm linked to a distribution network. This investigation includes the execution of a Static Synchronous Compensator (STATCOM) as a dynamic reactive power compensator at the Point of Common Coupling (PCC) to maintain the steady voltage during and after the disturbances. The established system is simulated in MATLAB/Simulink and the results show that the STATCOM upgrades the voltage stability and thus helps the wind turbine system to remain in service during grid faults.
