Abstract
This article presents a digital control strategy based three-phase Active Harmonic Current Compensation (AHCC) to enhance power quality in the distribution power system. A Synchronous Reference Frame (SRF) theory is applied to extract the fundamental and harmonic components from the distorted line currents. A simple and efficient unit vector method is adopted in the synchronous reference frame controller without use of phase locked loop for vector orientation. The AHCC is implemented with Voltage Source Inverter (VSI) and its gate control switching pulses are generated from Space Vector Modulation (SVM) technique with dead band time of 4.8μs. The projected SRF with direct current control SVM technique is validated through MATLAB program and also coded by assembly language for digital hardware implementation. The digital controller is experimentally evaluated through TMS320F240 digital signal processor for 10kVA rating of active harmonic current compensation system.
