雙變流器補償式UPS控制研究

摘要：文章介紹了三相雙變流器串并聯補償式UPS的工作原理，詳細討論了其基于同步旋轉坐標系下的控制系統方案，同時進一步提出一種改進控制策略．即在同步旋轉坐標系下采取PI加重復控制。仿真結果表明，該控制系統可以實現雙變流器串并聯補償式UPS全部控制功能。 Abstract：The paper introduces the operation principle and describes the control system scheme using Synchronous Reference Frame(SRF)of a three phase series parallel compensated 1ine interactive UPS system in detail，at the same time bring out a repetitive control under Synchronous Reference Frame. Simulation results verify this control system can make this kind of UPS carry out all of the control goals.
