基于比例重复的T型三电平并网变换器控制研究
Control Strategy Research of T-type Three-level Grid-converter with Repetitive-proportion
摘要
Abstract
The work mechanism and mathematical model of T-type three level converters were detail analyzed,in view of that the traditional PI control strategy can not meets the requirement of system high-performance index,at the same time,and proportion of quasi resonant design of control system is too cumbersome. The control strategy named proportion and repetitive compound strategy with voltage feed-forward decoupling was adopted in the current inner loop to achieve the interconnection of the rectifier unit power factor control. The detailed theoretical analysis and design were given. To test and verify the feasibility of the control strategy ,a complete system simulation model and experimental platform were built,the results show that the design and the control strategy can effectively improve the system performance,the input current THD get improved significantly,the control strategy is simple and easy digital realization,the system dynamic and static characteristics are good.关键词
