摘要:

锂电池储能系统是构建新型电力系统,实现双碳战略目标的关键支撑,但锂离子电池储能系统的消防安全问题成为了制约储能系统大规模推广的关键瓶颈,现有基于固定建筑物式的传统气体灭火系统适用性不强,无法扑灭锂离子电池火灾及抑制复燃。本工作面向典型预制舱式锂离子电池储能系统,基于多层协同预警技术和不同防护灭火策略实现了对储能系统的靶向消防防控装备开发。首先,基于烟/温感探测器、可燃气体传感器、Pack温度传感器构建了多层协同的预警技术,实现对电气火灾、锂离子电池火灾的精准预警。其次,在现有七氟丙烷灭火系统基础上增加锂电池火灾专用抑制系统,满足国标电气场所消防设计要求的同时保障锂电池火灾抑制需求。通过主管道、应急管道、喷嘴的布局定位安装,所设计的抑制系统支持Pack级主动防护,能将锂离子电池抑制剂输送到Pack,实现对锂离子电池火灾的早期扑灭并能多次启动,抑制锂离子电池火灾复燃及蔓延。灭火系统和抑制系统协同作战,各自发挥优势,全方位保障锂离子电池储能系统的安全。

Abstract:

Lithium-ion battery energy storage system has a fire safety problem that has become a key bottleneck restricting its large-scale promotion. The existing traditional gas fire extinguishing system based on fixed buildings has low fire extinguishing efficiency. Thus, this research work aimed at developing a prefabricated cabin-type lithium-ion battery energy storage system. Here, a targeted fire prevention and control equipment for an energy storage system was developed based on multi-layer collaborative early warning technology and different protection and fire-extinguishing strategies. First, a combustible gas sensor and Pack temperature sensor, which is an accurate, reliable, economical and practical multi-layer early warning technology, were built based on smoke/temperature detector. Second, lithium-ion battery fire-suppression system was added based on a heptafluoropropane fire-suppression system to meet the requirements of fire suppression of lithium batteries and the national standard electrical and fire protection design. The designed fire-fighting equipment supports multiple start of multi-point packs, which can effectively inhibit the re ignition of lithium battery fire. The combination of a fire-extinguishing system and a fire-suppression system ensure the safety of lithium battery energy storage system in all aspects.
