储能装置故障检测及重组技术的研究

摘要

蓄电池组和超级电容器组等储能装置是由大量的单体元件通过串、并联构成的,由于单体元件的性能不一致,为这些储能装置的安全、可靠运行带来了不利的影响.具有故障检测及自动重组功能的储能装置,可以实时对其内部的单体元件进行检测,并在发生故障后,自动利用备用储能单元和重组母线替换掉故障元件,实现重组功能,进而可以有效提高储能装置的整体性能,更好地满足实际需求.%Some energy storage devices, such as battery pack and super - capacitor banks, consist of a lot of monomers which are in series and parallel. These monomers are not the same in performance, that had a adverse impact for energy storage devices safe and reliable operation. The energy storage device with fault detection and restructuring can detect each monomer on real time, and replace the fault monomer with the backup unit automatically. So it can effectively improve the performance of energy storage devices, to better meet the actual demand.
