Abstract

To address the issue of high-frequency circulating current (HFCC) in a multi-machine parallel UPQC system, an equivalent model for zero-sequence circulating current (ZSCC) is devised following a thorough analysis of ZSCC pathways. According to different excitation sources, ZSCC is divided into two classes: switching ZSCC and mixed ZSCC. The causes and characteristics of HFCC are analyzed, and the reduction measures are put forward. Finally, a simulation model has been constructed using Matlab/Simulink software to validate the accuracy and efficacy of the HFCC model analysis and reduction techniques.
