Fire early alarm system and method for energy storage power station

Abstract

The invention discloses a fire early alarm system and a method for an energy storage power station. The system comprises one or more battery compartments, a monitoring room, an energy storage converter and a fire extinguishing system, a battery management system, a battery switch and an energy storage battery that are arranged in the battery compartments The battery compartments are provided witha data collection control unit, a gas detector and a mobile camera. The monitoring room is provided with an image recognition and data interaction server, wherein the data collection control unit, theimage recognition and data interaction server, the battery management system, the energy storage converter and the fire extinguishing system of the energy storage power station exchage information. The system establishes a three-level early alarm system by monitoring combustible gas in the battery compartments and image data, and can discover a thermal runaway phenomenon and a fire hazard of theenergy storage battery in time. The method sends local and remote operation control commands according to a predetermined strategy, improving intelligent degree of the fire early alarm in the energy storage power station, ensuring sensitivity, reliability and real-time performance of the early alarm effect.

Description

technical field [0001] The invention relates to the field of energy storage technology, in particular to an intelligent fire warning system and method for an electrochemical energy storage power station. Background technique [0002] Energy storage technology realizes the time-space transfer of energy and the secondary distribution of power flow and energy flow. Under the background of increasingly serious global energy problems, energy storage provides a new idea for the consumption of renewable energy and is an important aspect of green energy construction. technical means. Therefore, the rapid promotion of power system energy storage business, on the one hand, enriches the service scenarios of the power grid itself, such as peak regulation, frequency regulation, backup, and emergency response to accidents, and on the other hand, it also has far-reaching social effects and demonstration significance. [0003] In recent years, electrochemical energy storage power stations ...

AI Technical Summary

Problems solved by technology

The large-scale construction of energy storage power stations has brought new challenges to the safe production of power systems. The main reason for energy storage safety accidents is that lithium batteries are flammable, accompanied by thermal runaway. Fire accidents have caused great harm to the development of energy storage power stations. Impact

[0004] Although the battery compartment of the existing electrochemical energy storage power station is equipped with battery temperature monitoring, smoke detection, and temperature detection monitoring, due to the low resolution of the infrared and visible light cameras and the fixed installation method, it is impossible to detect the temperature of the battery after thermal runaway in time. Combustible gas after sudden change and safety valve opening cannot realize early fire monitoring and early warning
