Problems solved by technology

Once a safety problem occurs, it often causes a chain reaction of battery combustion, leading to a loss of control and heavy losses
[0004] 2) In the battery energy storage system, the voltage of the battery pack is generally above 700V, and the high-voltage DC system puts forward extremely high requirements for system insulation and protection; All may cause insulation drop, resulting in electric leakage, sparking, and cable contact resistance increase heating, etc., causing safety accidents
[0005] 3) In the grid-side battery energy storage system, the complex system often produces a harsh electromagnetic environment, which leads to false alarms and malfunctions of the system, and unpredic

Abstract

The invention discloses a wireless technology-based fire extinguishing system for an energy storage station. The fire extinguishing system is composed of all or parts of equipment such as a wireless fire alarm controller, a wireless fire detector, a wireless manual fire alarm button, a wireless fire acousto-optic alarm, a wireless module and a wireless repeater; a LoRa wireless communication function of the system is compounded into each component in the system to be realized; and based on fire characteristics of a lithium battery, an online early warning decision system, a multi-combination high-sensitivity detection system, a total-flooding automatic fire extinguishing system, a long-time protection cooling system, a manual backup means and other omnibearing, multi-angle and comprehensive control schemes are adopted. The fire extinguishing system has the functions of fire real-time detection and automatic fire extinguishing of the energy storage station.

Description

technical field [0001] The application belongs to the field of electric power system fire protection, and mainly relates to a wireless fire protection system for an energy storage station and a control method thereof. Background technique [0002] The battery energy storage system is composed of battery pack, battery management system BMS, energy storage converter PCS, air conditioner, dynamic environment monitoring, rack and accessories. In addition to the possible electrical safety of the energy storage converter PCS, air conditioner, and dynamic environment monitoring, the battery pack has become the biggest safety hazard. The potential safety hazards in the energy storage system are as follows: [0003] 1) In the battery energy storage system, the battery capacity of the battery pack is often as high as MWH, and in a container or a local space, the energy density is extremely high; in a local area, the capacity is as high as tens to hundreds of MWH. Once a safety probl...
