Abstract

The invention provides a fire warning method for a battery prefabricated cabin of a lithium iron phosphate energy storage power station, and relates to the field of fire protection. A fire alarm controller, a fire detection alarm system and a fire extinguishing system which are connected to the fire alarm controller, a BMS battery management system, and a combustible gas explosion-proof system connected to the BMS battery management system are arranged in the battery prefabricated cabin. A combustible gas monitoring device is added to the fire detection alarm system, alarm thresholds in earlywarning and later warning stages are set respectively during combustible gas monitoring, and the combustible gas explosion-proof system and the fire extinguishing system are controlled to act in different alarm stages respectively. Through two-stage multi-level fire warning set according to combustible gas monitoring, the accuracy and reliability of thermal runaway detection warning for lithium iron phosphate batteries are improved, and safe operation of an energy storage system is guaranteed.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a fire warning method for a battery prefabricated cabin of a lithium iron phosphate energy storage power station. Background technique [0002] The lithium iron phosphate battery itself has safety issues that cannot be ignored. In large-scale energy storage applications, the increase in the quality, quantity, capacity, and energy density of batteries will greatly increase the possibility and danger of accidents. In addition, there are fewer on-site personnel in energy storage applications. If it is unreasonable, there may be a chain disaster affecting the overall system, which will have an impact on the power quality and stability of the local power grid. Lithium iron phosphate batteries will release obvious characteristic parameters before thermal runaway occurs. Through the changes of these characteristic parameters, it can be judged whether the battery is about to experience th...
