DSTATCOM with Artificial Intelligent Controller for Voltage Sag Mitigation

Abstract: Fault at 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 Fuzzy logic controller implemented for the distributed system. The proposed method is implemented by using MATLAB/SIMULINK.

Keywords: DSTATCOM, Voltage sag, FIS, MATLAB SIMULINK.
