柔性低频输电系统高频谐振问题研究
Research on high-frequency resonance in flexible low-frequency AC transmission systems
摘要
Abstract
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 nonlin-ear 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 in-vestigates 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.关键词
