研究了蓄电池储能系统中闪弧危险的计算方法。缺乏国际统一标准，加上可预见的越来越多的使用BESS，使这个问题非常有趣，特别是由于实际涉及到电弧闪光危险与BESS维护操作。一个锂离子电池电路模型，由TERNA（意大利输电系统运营商）进行的实验短路测试和非线性电弧电阻模型的基础上，用于评估与电弧闪光相关的入射能量。然后，提出并讨论了能够将入射能量降低到安全值8 cal/cm 2以下并基于安装快速熔断器的高效和具有成本效益的解决方案。
This paper deals with the arc-flash haz ard calculation in battery energy storage systems (BESSs). The lack of international harmonized standards, coupled with a foreseeable increasing use of BESSs, makes this subject very interesting, especially due to the practical involvements related to arc-flash hazard associated with BESS maintenance operation. A Li-ion battery circuit model, based on experimental short-circuit tests conducted by TERNA (the Italian transmission system operator) and a non-linear arc resistance model are used to assess the incident energy related to arc-flash. Efficient and cost-effective solutions, able to reduce incident energy below the safe value 8 cal/cm2 and based on the installation of fast-acting fuses, are then proposed and discussed.
