jee.11.1.13673 ANT Colony Optimization Based Shunt Active Power Filter For Harmonic Compensation Shubhendra Yadav Satyendra Singh Journal on Electrical Engineering 2230–7176 11 1 19 26 https://doi.org/10.26634/jee.11.1.13673 ACO (Ant Colony Optimization), Controlled Rectifier, Hysteresis Current Controller, PI Controller, p-q Theory, Shunt Active Harmonic Filter This paper presents a comprehensive study on the performance of Shunt Active Harmonic Filter (SAHF) for harmonic compensation, where Ant Colony Optimization technique is used for optimization purpose. This optimization technique operates for the optimal PI control parameters which regulate the DC link voltage. Instantaneous real and reactive power (p-q) theory is used for calculating compensating currents. The simulation results show that Shunt Active Harmonic Filter (SAHF) for six pulse controlled rectifier proves to be very effective in mitigation of the harmonics present for various firing angles. The simulation is carried out with the help of MATLAB-SIMULINK tool box. July - September 2017 Copyright © 2017 i-manager publications.
