摘要
文章介绍了三相双变流器串并联补偿式UPS的工作原理,详细讨论了其基于同步旋转坐标系下的控制系统方案,并进一步提出一种改进控制策略.即在同步旋转坐标系下采取PI加重复控制。仿真结果表明,该控制系统可以实现双变流器串并联补偿式UPS全部控制功能。
The paper introduces the operation principle and describes the control system scheme using Synchronous Reference Frame(SRF)of a three phase series parallel compensated line interactive UPS system in detail,at the sametime bring out a repetitive controlunder Synchronous Reference Frame.Simulation results verify this control system can make this kind of UPS carry out all of the control goals.
