Single Phase Harmonic Mitigation Using Particle Swarm Optimization in Shunt Adaptive Power Filter

Abstract

Purpose – These load sources are the main cause of generating harmonics, generating power loss in the transmission system and electrical equipment system, as well as reducing the life of electrical equipment, reducing the accuracy of electrical measuring devices, and reducing the signal transmission of communication devices. Methodology/Approach – This study applies the Particle swarm optimization (PSO) algorithm to DC-link capacitor voltage control based on the Proportional-integral (PI) control algorithm to determine the reference current. MATLAB/Simulation 2019a is used to simulate research results. Findings – The harmonic compensation performance of the SAPF circuit gives good results and meets the standard for total harmonic distortion (THD) of less than 5%. Originality/Value of paper – Bridge rectifiers with RL load and Non-linear load with active RC are applied in a single-phase power supply. The single-phase voltage source inverter is used to shunt the adaptive power filter (SAPF) to compensate for reactive power and current harmonics.
