摘要:

变电站中,蓄电池组作为站内直流电源,其性能及可靠性对变电站供电系统的正常工作起着至关重要的作用。蓄电池组电池数量庞大,电池之间难免存在个体差异,在充放电过程中易造成电压不均衡,从而影响蓄电池组的整体性能,因此对电池组采取电压均衡措施具有重要意义。本文讨论了几种实际应用中常用的电池组电压均衡方案,在分析比较的基础上提出了一种新颖的能量变换均衡法,并通过仿真分析了该方案的可行性。

Abstract:

Accumulator system, which can be used as DC sources of power substations, is of great significance to the power supplying system. However, the imbalance of voltages between different batteries is a restraining factor to the overall performance of accumulator system. Three different kinds of voltage balancing methods are discussed in the article, based on which a novel balancing method with DC-DC converter is proposed, and then the practicability of the method is analyzed through simulation.

Key words: Accumulator, DC-DC converter, energy loss, voltage balance
