摘要:

针对传统串联型直流电源存在单体电池开路,影响整组电池供电可靠性及蓄电池必须脱离母线核容的问题,提出一种基于蓄电池守护组件的新型直流电源系统。系统通过蓄电池守护组件提高直流电源系统供电可靠性,并具备蓄电池在线核容等功能。依照相关规程,对某110 kV变电站进行方案实施,系统试验结果及运行情况符合设计预期,证明所提方案具有应用、推广价值。

Abstract:

In response to problem single battery open circuit in traditional series DC power supply to lead to decrease the reliability of the entire battery power supply and require the battery to detach from the bus core capacity.A new DC power supply system based on the battery guard component is proposed.The system improves the reliability of the DC power supply system through battery protection components,and has functions such as online battery capacity verification.According to relevant regulations,a scheme for a 110 kV substation is implemented.The system test results and operating conditions meet the design expectations,which can prove that the proposed scheme has application and promotion value.

Key words: battery guard, DC power supply, online battery capacity detect, substation
