A Novel Design of UPQC with Kalman Filter for Mitigation of Voltage and Current Disturbances


Article Preview

In this project proposed a new concept of optimal utilization of a unified power quality conditioner. The series inverter of the UPQC is controlled to perform simultaneous voltage sag/swell compensation and load reactive power sharing with the shunt inverter. Kalman filter is designed to remove the harmonic components of the supply voltage and load current. The proposed method operates both in the time and frequency domains allowing the selective compensation of voltage and current harmonics with fast dynamical responses. The simulation is conducted by using MATLAB/SIMULINK. The simulation result shows the proposed UPQC has a good effect in the mitigation of the voltage sag.
