High-order harmonic resonance phenomena of a voltage-sourced converter in cable system

This paper presents high-order harmonic resonance phenomena of voltage-sourced converters (VSC). When a voltage-sourced converter is connected to a power system with cables, there is a possibility that minute high-order harmonic voltages of a voltage-sourced converter are magnified by a series resonance and a parallel resonance, and high-order harmonic resonance phenomena are determined by this study. The cause of high-order harmonic resonance phenomena is investigated and elucidated by the analysis using EMTP. In addition, it is verified that high-order harmonic resonance phenomena occur as a practical matter. © 2004 Wiley Periodicals, Inc.
