A novel ann based harmonics mitigation and monitoring approach of shunt active power filter

Abstract

A new approach to monitor the power quality terms like harmonics, voltage sag or swell, flicker etc., in the distributed power system using shunt active power filter (SAPF) and controlling the filter using Artificial Neural Network (ANN) has been proposed in this paper. Harmonics are identified and mitigated using MOSFET based SAPF and controlled by ANN. Power quality has been monitored in the online for the domestic electronic applications. Comparing to PI controller ANN has better performance. Performance of the proposed technique has been shown in the Simulation results based on the parameter Total Harmonic Distortion (THD). Simulation has been done in MATLAB simulink. Online Monitoring has been carried out using PHP and SQL server.
