分析了现有DC?BANK抗“晃电”直流支撑系统中蓄电池组的变压方案。针对某型具体DC?BANK系统中系统参数的设定，提出传统系统中蓄电池利用率低的问题。针对蓄电池本身的放电特性及DC?BANK系统对蓄电池组的使用实际，提出采用一种对蓄电池组输出电压进行升降压变换的方案来解决现有系统中不能充分发挥蓄电池性能的不足。仿真证明电路性能达到预定指标，实现了对蓄电池组输出电压的升降压变换和延长系统的设计支撑时间的目的，解决了传统DC?BANK抗“晃电”直流支撑系统中蓄电池组性能不能充分发挥的不足。

The voltage transformation scheme of battery set in DC support system used in available DC?BANK anti?shake system is analyzed. The low use rate of the battery in traditional systems is discovered in parameter setting of a DC?BANK sys?tem. According to the discharging characteristics of battery and the DC?BANK system’s requirement to batteries,a buck?boost conversion scheme for battery output voltage is adopted to improve use rate of battery. Simulation results indicate that the design is able to achieve the assumed index that the stable buck?boost conversion of output voltage of the battery group is realized and the system support time is lengthened. In other words,the deficiency that battery property cannot be fully used in traditional DC?BANK anti?shake system has been solved.
