一种基于蓄电池抽头分组的守护型直流电源系统及其控制策略OA

The traditional DC power supply system adopts a series connection structure of batteries,which has problems such as low reliability,high energy consumption of manual battery capacity,and safety hazards.A guardian DC power supply system based on battery tap grouping and its control strategy are proposed without changing the traditional DC system structure.By grouping and boosting parallel batteries to achieve redundant power supply to the bus,the problem of bus voltage loss caused by single battery failure in the battery pack is solved.The reliability of DC bus power supply is improved.At the same time,a protective DC power supply system's automatic capacity allocation strategy is proposed to reduce energy loss during manual capacity allocation and improve the maintenance efficiency of DC power supply equipment.
