Distribution System Power Quality Improvement using IRP Theory

Abstract

A shunt active power filter is suggested in this study. In power plants, there are different power electronic converters, which leads to power quality problems including harmonic noise and voltage swings that decrease the life of the equipment. Shunt active power filters decrease harmonics, voltage swings, and the insistence for reactive power from nonlinear loads in 1-ph (2 wire), 3-ph with neutral (4 wire), and 3-ph without neutral (3 wire). Using the pq theory, the reference compensating current is retrieved. The simulation results verified MATLAB 2015a software. Different MATLAB results are verified during the steady-state and dynamic state. The simulation results are verified output voltage, output current and THD.
