| 摘 要： | 介绍了一种基于超导储能(SMES)的并联处理不间断供电系统(UPS),该系统仅采用一套双向电流型变流器,利用超导线圈作为直流侧储能元件,可对多项电能质量指标进行综合调节.作者根据装置的结构特点和工作原理,提出了一种基于电源电流"预补偿"的解耦和前馈补偿控制策略,并通过样机实验验证了该装置结构和文中提出的控制方法的有效性.

| Abstract: | A superconducting magnetic energy storage (SMES) based parallel processing uninterruptible powersupply (UPS), which can realize multiple power qualityconditioning functions, is described. In this device only one bi-directional current source converter is employed andSMES coil is used as storage component. In accordancewith the structural feature and working principle of thedevice, a decoupling and feed forward compensatingcontrol strategy based on the pre-compensation for supply current is presented. By means of the experiment withprototype model, the effectiveness of the presented control method and the structure of this device are verified. |
