Abstract: Fault at transmission or Distribution level cause transient voltage sag in entire system or large part of it. Disturbances such as voltage sag, swell, short duration interruption, transient and harmonic occurs. Fault on 11Kv system or at load point affects voltage profile of other feeders. Unsymmetrical fault effect on distribution line and voltage restoration using DSTATCOM which is a custom power device. This paper deals with two control methods such as PI controller and Fuzzy logic controller implemented for the injection of current. The proposed method is implemented by using MATLAB/SIMULINK.
Keywords: Dstatcom, Voltage Sag, FIS, PI Controller, Matlab Simulink.
