A single-phase current vector control for a DSTATCOM installed in distribution systems

Abstract

This paper demonstrates an effective control technique for a Distribution STATic COMpensator, (DSTATCOM), as a custom power conditioner to mitigate the current fluctuation and voltage flicker in industrial distribution systems. The proposed control is newly utilized for a single-phase DSTATCOM, and it depends on a current vector control technique for generating the required reactive power. It is known that the current vector control is commonly implemented on a three-phase system to operate the three-phase DSTATCOM. The novelty in this paper is articulated in the implementation of the current vector control on a single-phase circuit to operate a single-phase DSTATCOM. The presented ideas are conveyed and approved through simulation results using MATLAB/SIMULINK along with a real time-domain model of the arc furnace.
