Synchronous Reference Frame with Finite Impulse Response Filter for Operation of Single-phase Shunt Active Power Filter

Abstract

Power Quality (PQ) has been recognized as one of the main issues in electricity supply worldwide after the invention of nonlinear load. In 2017, PQ problem leads to significant economic losses in the Pan European region. Therefore, Active Power Filter has been developed during the past two decades to improve the harmonic compensation, reactive power, and voltage balance. In this research, the evaluation of the Synchronous Reference Frame (SRF) method is done under nonlinear load condition. The objective of this research is to modify the harmonic extraction algorithm based on SRF concepts for the application of single-phase shunt active power filter (SAPF) in harmonics mitigation and evaluate the performance of it. The performance of the SAPF that used SRF is evaluated and verified using MATLAB/Simulink. Besides that, the proposed SRF will be benchmarked with several existing techniques. The results are verified using MATLAB/Simulink with the aid of Powergui in the SimPower System block. Powergui has a built in Fast Fourier Transform (FFT) analysis tool that could perform harmonic analysis. With the aid of this tool, the Total Harmonic Distortion (THD) value can be viewed in the block. This research does achieve the THD value of the power system keeps under the limit set by IEEE standard 519.
