This paper offers a new auxiliary damping control approach based on the wide area measurement system (WAMS) totally to depress sub-synchronous resonance (SSR) in doubly-fed induction generator (DFIG), which is primarily based on wind farms linked to series capacitive compensated transmission networks. In addition, wide area measurement systems have caused their use in power systems with the advancement of technology. However, the delay in sending measurement signals is considered as an important point in spite of all of its benefits if this latency could go to pot the damping overall performance of control approach. This paper presents a fuzzy approach damping controller (FLWADC) to mitigate SSR for the time delay. The FLWADC is a supplementary signal at the stator voltage of the gird-side converter (GSC) of DFIG- based wind farms FLWADC executed by using voltage and the present day of compensating series capacitive because of its established robustness against input sign versions inside the proposed manipulated approach. The effectiveness and validity of the proposed additional damping control were verified on a modified version of the IEEE first benchmark model via time simulation analysis by using Matlab/Simulink.
