Abstract-In this paper, voltage sag compensation of point of common coupling (PCC) using a new structure of fault current limiter (FCL) is proposed. The proposed structure prevents voltage sag and phase angle jump of substation PCC after fault occurrence. This structure has a simple control method. Using semiconductor switch (IGBT or GTO) at dc current rout leads to fast operation of the proposed FCL and consequently, dc reactor value is reduced. On the other hand, the proposed structure reduces total harmonic distortion (THD) on load voltage and it has low ac losses in the normal operation. As a result, other feeders which are connected to the substation PCC will have good power quality. Analytical analysis, simulation results using PSCAD/EMTDC software and experimental results are presented to validate effectiveness of this structure.
