Research on high-frequency resonance in flexible low-frequency AC transmission systems
Flexible low frequency AC transmission system employ power electronic converters， particularly modular multilevel matrix converters （M3C）， to enable low-frequency operation. These converters demonstrate highly nonlinear dynamic characteristics during grid-connected operation， and their interaction w...

| description | Flexible low frequency AC transmission system employ power electronic converters， particularly modular multilevel matrix converters （M3C）， to enable low-frequency operation. These converters demonstrate highly nonlinear dynamic characteristics during grid-connected operation， and their interaction with AC transmission systems can potentially trigger high-frequency resonance phenomena. Based on an actual engineering case study， this paper investigates the mechanism of high-frequency resonance occurring on the low-frequency side of LFAC transmission systems. The analysis incorporates field test data and results obtained from real-time digital simulator （RTDS）， while systematically examining factors that may influence resonance characteristics. |
