Performance analysis of interline unified power quality conditioner (IUPQC) with PI and fuzzy controllers

Todays power distribution system suffers with quality and continuity of the power. Interline Unified Power Quality Conditioner (IUPQC) is combo of Series and shunt connected second order devices for enhance the power quality(PQ) in distribution system. The paper compares efficiency of IUPQC with Fuzzy Logic (FL) and Proportional Integral (PI) Controller in PQ enhancement in two feeder utilization system. The proposed IUPQC provides compensation in Voltage disturbances like sag/swell and reduction in Total Harmonic distraction. The efficiency of the proposed configuration has been verified and compared with PI and FL Controllers configuration through simulation studies using MATLAB/SIMULINK.
