- Abstract:
- Under the background of carbon peaking and carbon neutralization, renewable energy such as wind and light will gradually become the dominant energy. However, its power generation is discontinuous and unstable, which requires to install energy storage facilities. Lithium iron phosphate battery energy storage prefabricated cabin is widely used in the market. However, lithium iron phosphate batteries have high risk of thermal runaway and fire hazard, and the current fire protection design standards are low. The fire characteristics of lithium iron phosphate battery and the applicability of fire extinguishing medium were investigated, and water-based fire extinguishing agent was determined to be more suitable to be selected as the extinguishing medium. Based on the results of fire water mist extinguishing test of lithium iron phosphate battery module in energy storage power station and the lessons of fire accident in energy storage power station, the fire water supply measures suitable for lithium iron phosphate battery energy storage prefabricated cabin were explored, and the relevant design parameters were proposed. Combined with engineering examples, the design scheme of fire water supply system for lithium iron phosphate battery energy storage prefabricated cabin was determined: a water mist fire extinguishing system was installed in the energy storage prefabricated cabin, and an external cooling water system was installed in the fire cabin and adjacent cabins.
