The sliding mode control for a series active power filter to improve power quality (Thai)

Abstract

This paper outlines causes of the power quality problem especially those which occur with a three-phase voltage. The problem solving methods involving use of a sliding mode control technique with a series active filter to improve such power quality are reviewed. The basic concept of sliding mode control including a flowchart of the voltage compensation technique is described. And finally, the technique is tested to solve some case studies of power quality problems through computer simulation in order to show its efficiency and capability.
