Research on Suppression Method of Circulating Current for Modular Multilevel Converter
摘要
Abstract
The modular multilevel converter (MMC) had been widely studied and applied in the medium and high voltage direct current (HVDC) transmission system.The existence of internal circulation was an important phenomenon in MMC.According to the mechanism of MMC topology and its internal circulation,its three-phase circulation was divided into 2 DC components based on negative-sequence coordinate transformation of double fundamental frequency.And a circulating current suppressing controller was designed.The simulation results showed that the cotroller could effectively suppress the circulation of arm current and reduced the distortion of waveform without negative impacts on MMC external output AC voltage and current.关键词
