Description

Technical Field

[0001] The present application relates to the field of electrochemical energy storage technology, and in particular to an electrochemical energy storage early warning-alarm-fire extinguishing linkage method. Background Art

[0002] Electrochemical energy storage is a technology that uses chemical reactions to store and release electrical energy. It plays a vital role in the modern energy system. On the power generation side, electrochemical energy storage can smooth the fluctuations in renewable energy output and improve the stability of the power grid; on the power grid side, electrochemical energy storage can achieve peak shaving and valley filling, frequency regulation and other functions; and on the user side, electrochemical energy storage can reduce user costs and provide backup power support.

[0003] However, due to their structural characteristics, electrochemical energy storage batteries are easily affected by electrical abuse, mechanical abuse, and thermal abuse, which can lead to thermal runaway. Once thermal runaway occurs, it is very easy to produce chain reactions such as jet fire and explosion. Due to the particularity of electrochemical energy storage systems, the significant characteristics of electrochemical energy storage system accidents are that the accidents develop quickly, the accidents are very harmful, the post-event alarm and intervention effects are not obvious, and the batteries are very easy to reignite and cause chain explosions. At present, the fire monitoring of electrochemical energy storage systems is mainly based on smoke alarms and temperature sensors, which can only warn after the accident, and cannot accurately warn of the occurrence of thermal runaway. Fires caused by thermal runaway of electrochemical energy storage systems are extinguished by ordinary fire extinguishing methods, and no targeted fire extinguishing measures are set, resulting in low safety of electrochemical energy storage systems.

[0107] Specifically, the normalization processing of all parameters in the model is performed through the preset first fixed coefficient and the second fixed coefficient, so that each parameter is within the same value range.

[0108] Specifically, the greater the fire risk value, the greater the possibility of a fire occurring in the current monitoring sub-region.

[0109] Specifically, judging whether to generate an alarm instruction according to all the fire risk values includes:

[0110] Presetting a first fire risk value threshold F1 and a second fire risk value threshold F2, and F1 < F2;

[0111] If f i <F1, the i-th monitoring sub-region does not generate an alarm instruction at the current monitoring time node;

[0112] If F1 < f i <F2, the i-th monitoring sub-region is an abnormal sub-region at the current monitoring time node, and it is judged whether to generate an alarm instruction according to the equipment operation parameters of the abnormal sub-region;

[0113] If f i >F2, the i-th monitoring sub-region generates a first-level alarm instruction at the current monitoring time node, and the i-th monitoring sub-region is set as a fire sub-region.

[0114] Specifically, the first fire risk value threshold and the second fire risk value threshold can be set according to historical parameters.

[0115] Specifically, the first-level alarm instruction means that there is an open fire in the current monitored sub-region. The corresponding fire extinguishing strategy needs to be immediately activated to prevent the further spread of the fire.

[0116] Specifically, the fire extinguishing strategy is set according to the alarm instruction, including:

[0117] Obtain all the fire sub-regions at the current monitoring time node;

[0118] Establish a fire sub-region sequence A1 according to all the first-level alarm instructions at the current monitoring time node, A1 = (a 11 , a 12 ... a 1i ... a 1n1 ), where a 1i is the i-th fire sub-region; n1 is the number of fire sub-regions;

[0123] Generate the first-level fire extinguishing strategy at the current monitoring time node according to all the first-level fire extinguishing sub-paths and all the control sub-strategies.

[0124] Specifically, the fire sub-region refers to the monitored sub-region where there is a fire at the current monitoring time node. The spraying speed of the corresponding fire extinguishing sub-module is set according to the fire risk value corresponding to a single fire sub-region. Through the rapid response of each fire extinguishing sub-module, the fire trend can be controlled in time.

[0125] Specifically, by analyzing the position parameters of all the fire sub-regions, multiple first-level fire extinguishing sub-paths are determined, and fire extinguishing operations are carried out along the fire extinguishing paths by manual or drone to prevent the further spread of the fire in the fire sub-region and affect the adjacent monitored sub-regions. Control the fire in time and reduce the overall fire loss.

[0126] Specifically, by iteratively optimizing the historical fire protection parameters, the corresponding processing model is established, and the best first-level fire extinguishing sub-path can be quickly determined according to the real-time all fire sub-regions and the parameters of standby personnel and standby equipment, and the fire that has occurred can be effectively controlled in the shortest time.

[0127] It is understandable that in the above embodiments, multiple monitoring points are set within a single monitoring sub-region to collect gas concentration parameters, temperature change parameters, and image parameters within the monitoring sub-region, alarm for the area where a fire occurs, and at the same time quickly determine the corresponding fire extinguishing strategy, improving the efficiency of fire handling for electrochemical energy storage devices and reducing losses caused by fires.

[0128] In a preferred embodiment of the embodiments of the present application, determining whether to generate an alarm instruction according to the device operation parameters of the abnormal sub-region includes:

[0141] Specifically, the operating indexes include, but are not limited to, voltage fluctuation, current fluctuation, remaining life of the equipment, temperature change on the surface of the equipment and other parameters.

[0142] Specifically, the larger the operating abnormal value is, the greater the possibility of abnormal operation and fire caused by the electrochemical energy storage equipment in the corresponding radiation area is.

[0143] It can be understood that in the above embodiments, by collecting the operating parameters of the electrochemical equipment in each radiation area, secondary judgment is carried out, early warning is given to the equipment sub-module with abnormal operation in time, and replacement or maintenance is carried out by means of patrol inspection, so as to avoid fire caused by abnormal operation or aging of the equipment. The overall fire risk is reduced.

[0144] In the preferred embodiment of the present application, judging whether to generate an alarm instruction for the target abnormal sub-region according to all abnormal operation values includes:

[0149] If k > K1, the target abnormal sub-region generates a second-level alarm instruction and generates a second-level fire extinguishing strategy for the target abnormal sub-region according to the second-level alarm instruction.

[0150] Specifically, all parameters in the model are normalized by presetting a fifth fixed coefficient and a sixth fixed coefficient, so that each parameter is within the same value range.

[0151] Specifically, the larger the inspection evaluation value is, the greater the possibility of a fire occurring in the current abnormal sub-region.

[0152] Specifically, a first-level warning instruction means that there are some electro-chemical energy storage devices operating abnormally in the current abnormal sub-region, and inspections are required to promptly repair the abnormal devices to prevent fires caused by abnormal device operation.

[0156] Setting the working parameters of the fire extinguishing sub-module in the target abnormal sub-region according to the inspection evaluation value.

[0157] Specifically, a second-level alarm instruction means that a fire may occur at any time in the current abnormal sub-region. By setting the working parameters of the corresponding fire extinguishing sub-module, the abnormal sub-region is cooled down to prevent sudden fires. At the same time, the abnormal operation values of each radiation region are analyzed to generate an inspection strategy, and corresponding second-level fire extinguishing sub-paths are generated according to the inspection strategy. Staff members repair each electro-chemical energy storage device according to the second-level fire extinguishing sub-path and preprocess possible fires to reduce fire losses.

[0158] It can be understood that in the above embodiment, the abnormal sub-region is determined by diagnosing the operating status of each monitoring sub-region, and by analyzing the device operation parameters of each abnormal sub-region, potential fire risks are promptly warned and inspected, reducing the probability of fire occurrence and ensuring the safe operation of electro-chemical energy storage devices.

[0159] According to the first concept of the present application, by establishing multiple monitoring sub-regions, the electro-chemical energy storage devices are monitored in a partitioned manner, and multiple monitoring points are set in a single monitoring sub-region to collect gas concentration parameters, temperature change parameters, and image parameters in the monitoring sub-region, alarm for the area where a fire occurs, and at the same time quickly determine the corresponding fire extinguishing strategy, improving the fire handling efficiency for electro-chemical energy storage devices and reducing fire losses.

[0160] According to the second concept of the present application, the abnormal sub-region is determined by diagnosing the operating status of each monitoring sub-region, and by analyzing the device operation parameters of each abnormal sub-region, potential fire risks are promptly warned and inspected, reducing the probability of fire occurrence and ensuring the safe operation of electro-chemical energy storage devices.

[0161] The above are only the preferred embodiments of the present application.
