Impact of Connected Flicker Sources on DFIG Performance

Doubly Fed Induction Generator (DFIG) has become the most popular wind turbine generator that has been installed worldwide since a decade ago. It cannot be denied that the expansion of loads might be increased from time to time which might also influence the performance of DFIG. Moreover, at the same time, Fault Ride Through (FRT) must also be complied by the grid-connected DFIG. In this paper, an investigation of Flicker Disturbance on DFIG Performance is studied. The flicker disturbance could be sourced from pulsating loads such as arc furnace, compressor, and welding machine loads, it will affect the industrial production process and could cause fatigue due to loss of concentration as a contribution of eye epileptic when working under rapid blinking light. Additionally, when significant flicker sources connected to the system with DFIG, the FRT such as voltage profile at PCC and DC-Link might cause the protection system operates to disconnect the DFIGs from the grid.
