摘　　要：针对配网自动化终端DTU柜蓄电池内部存在不一致性,重复过充与过放导致蓄电池寿命缩短的问题,提出了一种基于变压器和振荡电路的高频脉冲工作方式下的双向能量转移均衡系统。此系统通过简单的操作实现电量从高电量单体电池向低电量单体电池的转移。将所提出的电池均衡系统应用于两节串联蓄电池并进行了仿真试验,结果表明,此均衡系统在速度、效率方面取得了良好的均衡性能。The present work seeks a solution to the inconsistency among batteries in data transfer unit which causes repeated overcharge and overdischarge,and consequently,shortening of the battery life.An equalization system,which is based on the high-frequency pulse working mode of transformer and oscillation circuit and enables bi-directional energy transfer,is proposed.This system realizes the transfer of power from battery with high state of charge to single battery with low state of charge via a plain mechanism.By applying the proposed system to the equalization of two series-connected batteries,the simulative experiment is carried out,the results of which verifies the satisfactory performance of the system in the aspects of both balance speed and efficiency.
