应用于MMC环流抑制的准PR控制器参数设计
Designing of parameters for quasi proportional-resonance controller applying to MMC circulation suppression
摘要
Abstract
Modular Multilevel Converter(MMC)phase-to-phase voltage imbalance results in internal generation of three-phase current.To restrain the circulation,an equivalent model of MMC circulation is firstly established,and the parameters of quasi PR controller are designed in the stationary coordinate system,and the influence of the parameters of quasi PR controller on the restraining characteristics of the MMC circulation is analyzed.In order to verify the proposed strategy,a PSCAD/EMTDC simulation model is built and tested on the 35 kV·A five-level MMC prototype.The results show that the designed quasi PR controller can suppress the internal circulation of MMC effectively.关键词
