2.2 Fire Characteristics of Electrochemical Energy Storage Power Station Electrochemical energy storage power station mainly consists of energy storage unit, power conversion system, battery management system and power grid equipment.
The information between the fire control room and each energy storage station can be transmitted by optical cable or wireless communication, and based on the communication protocol DL/T634.5101 and DL/T634.5104,the relevant secondary equipment is deployed in the security II area.
suppression equipment may or may not be provided as an integral part of an ESS, or it may be optional. Depending on the case, the ESS shall comply with all applicable performance requirements in the standard with and/or without the fire detection and fire suppression equipment in place and operational.
However, a number of fires occurred in recent years have shown that the existing regulations do not show sufficient recogni- tion of the fire risks of energy storage systems and specific fire early warning methods and fire-fighting measures have not yet been developed.
A fixed firefighting system does not stop an already occurring thermal runaway sequence within a battery module, but it can prevent fire spread from module to module, or from pack to pack, or to adjacent combustibles within the space. The afected module is likely to be fully lost, but the adjacent modules can be saved.
Setting up minimum separation from walls, openings, and other structural elements. The National Fire Protection Association NFPA 855 Standard for the Installation of Stationary Energy Storage Systems provides the minimum requirements for mitigating hazards associated with ESS of diferent battery types.
