Ventilation, water and gas fire-fighting linkage control method for energy storage power station

Abstract

The invention relates to a fire control technology for an energy storage power station, in particular to a ventilation, water and gas fire-fighting linkage control method for an energy storage power station. The method is characterized in that firstly, linkage control of a ventilation system and a fire-fighting system is combined, and when fire-fighting measures are started, the ventilation systemis closed; secondly, double fire-fighting measures of gas fire-fighting and water fire-fighting are adopted to carry out fire extinguishing control aiming at different fire conditions, specifically,if the temperature monitored through a temperature monitor is higher than T1, an alarm is adopted, after a smoke alarm monitors the smoke, the gas fire-fighting is adopted, and if the temperature monitor monitors that the temperature still further rises to T2, the water fire-fighting is started; and finally, a battery cabinet is taken as a unit, module type independent control is carried out, anda fan is controlled according to various monitors by logic 'or'. The method has the advantages that under the condition that it is ensured that a ventilation pipeline and the non-faulty battery cabinet are not affected, the loss is greatly reduced, and the influence on the operation of the energy storage power station is reduced.

Description

technical field [0001] The invention relates to a fire control technology for an energy storage power station, in particular to a linkage control method for ventilation, water and gas fire protection for an energy storage power station. Background technique [0002] In the energy storage power station, according to the specifications and requirements of operation safety, it is necessary to set up a ventilation system and a fire-fighting system. The fire-fighting system either uses a separate gas fire-fighting or a separate water fire-fighting system. The ventilation system adopts the bottom-in and top-out way to arrange ventilation ducts and air outlets. Therefore, space for the ventilation system needs to be reserved at the upper and lower parts of the energy storage power station, and the ducts and inlets required for the fire protection system are generally arranged under the upper ventilation ducts. , the outlets and pipes of the fire protection system are distributed ab...

Problems solved by technology

[0004] 1) Although the ventilation system and the fire protection system are installed independently, they both face the space inside the battery cabinet and are in a connected state. Since the fire protection system mostly uses water for fire protection, when the fire protection system is started, the ventilation system is often not closed, resulting in The fire-fighting water flows into the ventilation system, interfering with the operation of the ventilation system, and even causing a short circuit of the fan in the ventilation system, which expands the impact of the fire. In addition, the electrochemical substances in the battery cabinet may flow into the ventilation pipe with the fire-fighting water, contaminating and blocking the ventilation system

Moreover, since the ventilation system is connected to each battery cabinet, the fire water may flow into the side cabinet through the ventilation duct, causing a short circuit in the adjacent battery cabinet, and even causing a fire in the side cabinet.

[0005] 2) When the fire-fighting system uses gas fire-fighting alone, although gas fire-fighting is the preferred fire-fighting method for battery cabinets, the cost of gas-fired fire-fighting is high and it is difficult to achieve comprehensive installation. In existing energy storage power stations, gas-fired fire-fighting only uses isolated combustion media. In this way, It is easy to cause the battery that has already ignited to be unable to fully cool down, and it may also cause the release of combustion accelerants (such as oxygen) inside the battery to form chemical spontaneous combustion, so it is difficult to be widely used, making water fire protection the main fire protection solution for energy storage power stations

[0006] 3) The fire protection scheme of the energy storage power station is based on water fire protection. However, water fire protection is a destructive scheme. After starting, the whole cabinet battery will be scrapped due to water ingress, and it is easy to leak to the side cabinet or even the entire battery room

If the water fire protection is started only because of a small temperature rise or a small part of the battery failure, it is easy to lose the big because of the small loss, which not only causes economic losses, but also affects the continuous operation of the energy storage power station; and the replacement of the whole cabinet battery It is cumbersome and will directly affect the operation of the energy storage station

[0007] 4) Since the passages and pipes of the ventilation system and the fire protection system each occupy part of the space of the energy storage power station, the space utilization rate is low
