Voltage Flicker Mitigation Using VSC-Based STATCOM to Improve Power Quality

In electrical arc furnaces (EAF) load, one of the most extreme force quality issues is the voltage flicker. Because of the current advances in the semiconductor industry and as a result, compensators are emerging based on voltage source transformers, the use of FACTS devices has gradually been observed to compensate for voltage flashing. This paper is to review the present status of the simulation and usage of present control advances of STATCOM utilized in distribution systems to alleviate the fluctuating voltage. It was found that continued research and development efforts in this area are still required to improve the performance of systems, establish techniques to accurately predict their production and reliably integrate them with other power quality disorders. The adequacy of STATCOM utilizing Fuzzy and conventional PI controller has been analyzed. Here by using MATLAB/Simulink platform the simulation is being done and the performance is examined. By the simulation outputs it shows that fuzzy logic controller works better than the conventional controller.
