变电站蓄电池并列输出技术在贵州电网应用研究

Application of substation battery parallel output technology in Guizhou Power Grid

提出蓄电池并列输出技术,即把单节蓄电池与匹配的AC/DC充电模块、DC/DC升压模块等设计为"智能蓄电池模块",再通过多个模块并联后,为变电站直流负载供电。采用并列输出技术后可以解决串联方式下诸多问题,并大大提升直流系统运行可靠性。文章对蓄电池并列输出技术核心模块进行研究,并分析其应用方式和产生经济效益,为后续该技术具体实施和推广应用提供有力参考。

Put forward battery parallel output technique, smart battery module, which was designed by single battery, AC/DC module, DC/DC module. By using battery parallel output technology, the above mentioned problems in series batteries were smoothed out, and the workload and the cost of maintaining series batteries can be greatly reduced; moreover, the reliability of substation DC system was greatly enhanced. The core modules and application of battery parallel output technology were discussed, and the economic benefit was also analyzed. This paper would be helpful for the technology＇ s application and implementation in Guizhou Power Grid.
