Description

Technical Field

[0001] This invention relates to the field of energy storage safety control technology, and in particular to a method and system for the coordinated optimization of fire extinguishing system and liquid cooling system in an energy storage power station. Background Technology

[0002] As energy storage power stations develop towards higher capacity, higher power density, and integration, higher requirements are placed on safety control regarding heat accumulation, heat diffusion suppression, and fire handling within the battery compartment. Related safety control technologies are gradually evolving from single temperature monitoring and independent fire-fighting measures to a comprehensive monitoring and control approach that combines battery cluster temperature, liquid cooling circuit status, fire-fighting pipeline connectivity, and zoned operation information. Existing solutions typically maintain battery thermal balance through a liquid cooling system, and in the event of thermal anomalies or fire risks, the fire-fighting system performs targeted spraying, liquid injection, or release of extinguishing media to meet the basic safety requirements for energy storage unit operating temperature control and anomaly handling.

[0003] In application scenarios where liquid cooling systems and fire protection systems share some flow channels or media resources, existing control methods are mostly based on independent triggering of liquid cooling circulation state or fire injection state. Usually, flow channel switching is directly performed based on temperature anomalies or fire signals in the target area. However, insufficient consideration is given to the heating trend of adjacent zones, the overlap of shared flow channel paths, the limitation of media state, and feedback correction after handling. When the target zone needs rapid liquid injection and adjacent zones still need to maintain protective liquid cooling, the lack of coordinated constraints on switching and scheduling conditions makes it difficult for fire injection and liquid cooling circulation to form a continuous and matched control link in the same shared path. Summary of the Invention

[0004] In view of the aforementioned existing problems, the present invention is proposed.

[0005] Therefore, this invention provides a method for the coordinated optimization of fire extinguishing system and liquid cooling system in energy storage power stations to solve the problem of difficulty in coordinating the scheduling of fire-fighting liquid injection and protective liquid cooling in shared flow channels.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: In a first aspect, the present invention provides a method for the coordinated optimization of a fire extinguishing system and a liquid cooling system in an energy storage power station, comprising: collecting operational data of the energy storage power station and data of the shared flow channel for liquid cooling fire extinguishing, and performing time synchronization and zonal association to obtain coordinated monitoring data; matching the correspondence between the monitoring zones and the shared flow channel for liquid cooling fire extinguishing in the coordinated monitoring data, and determining the liquid cooling usage status and fire extinguishing usage status of the shared cooling fire extinguishing medium to obtain zonal coordinated status data; based on the zonal coordinated status data, identifying the risks of thermal anomalies in each zone, and marking the anomaly concentration area and the heat-affected area as the target zone and adjacent zones, respectively, to obtain the risk status; and based on the risk status, identifying... The working mode of the shared liquid-cooled fire extinguishing medium is determined, and the liquid-cooled circulation and fire injection scheduling of the shared cooling extinguishing medium are performed to obtain the medium scheduling results. Based on the medium scheduling results, the liquid-cooled fire extinguishing medium corresponding to the target zone is controlled to enter the corresponding working state. When there are adjacent monitoring zones, the liquid-cooled fire extinguishing medium corresponding to the adjacent zones is controlled to maintain the liquid-cooled circulation state, thus obtaining the liquid-cooled fire extinguishing collaborative control strategy. Based on the liquid-cooled fire extinguishing collaborative control strategy, the working state control of the target zone and the protective liquid-cooled control of the adjacent zones are executed. Execution feedback data is collected, and the scheduling conditions of the shared cooling extinguishing medium and the switching conditions of the shared liquid-cooled fire extinguishing medium are corrected to obtain the collaborative optimization control parameters.

[0007] As a preferred embodiment of the collaborative optimization method for the fire extinguishing system and liquid cooling system of the energy storage power station described in this invention, the specific steps for obtaining the collaborative monitoring data are as follows: Collect operational data of the energy storage power station and data of the liquid-cooled fire-fighting common channel. Time-align the operational data of the energy storage power station and the data of the liquid-cooled fire-fighting common channel according to the collection time. Then, remove abnormal data and fill in missing data after time alignment to obtain synchronous monitoring data. Based on the monitoring zone number, the liquid-cooled fire protection common channel number, and the installation correspondence between the liquid-cooled fire protection common channel and the monitoring zone, the synchronous monitoring data is partitioned and merged to obtain collaborative monitoring data.

[0008] As a preferred embodiment of the collaborative optimization method for the fire extinguishing system and liquid cooling system of the energy storage power station described in this invention, the specific steps for obtaining the partitioned collaborative state data are as follows: Based on collaborative monitoring data, the installation location of each monitoring zone and the connection location of the liquid-cooled fire protection common flow channel are read. The supply liquid path, return liquid path and fire injection liquid path corresponding to the same monitoring zone are merged to obtain the flow channel path of the zone. Based on the zoned flow path, the continuity of supply and return liquid in the liquid cooling circulation state is identified and the liquid cooling available path is marked. The continuity of directional liquid injection in the zoned flow path in the fire-fighting liquid injection state is identified and the fire-fighting available path is marked. Based on the available paths for liquid cooling and fire protection, the liquid cooling and fire protection usage status of the shared cooling and extinguishing media are divided into available status, restricted status, and unavailable status to obtain the media status results. Write the zone flow path, liquid cooling available path, fire protection available path, medium status results, and the zone thermal change status of the corresponding monitoring zone into the corresponding monitoring zone to obtain the zone collaborative status data.

[0009] As a preferred embodiment of the collaborative optimization method for the fire extinguishing system and liquid cooling system of the energy storage power station described in this invention, the step of identifying the risk of thermal anomalies in each monitoring zone based on the zoned collaborative status data, and marking the anomaly concentration area and the heat-affected area as the target zone and adjacent zones respectively, to obtain the risk status, is as follows: Based on the zone collaborative status data, the zone thermal change status of each monitoring zone is compared with the preset normal thermal status to obtain the zone thermal anomaly degree. Based on the degree of thermal anomaly in each zone, and combined with the available liquid cooling paths, the thermal anomaly suppression status of each monitoring zone is identified, and the monitoring zones where the degree of thermal anomaly continues to increase and the thermal anomaly suppression status decreases are marked as anomaly concentration areas. Based on the areas of concentrated anomalies, the heating change trends of the monitoring zones surrounding the areas of concentrated anomalies are identified. Combined with the flow path of the zones, the surrounding monitoring zones that have heating change trends and are associated with the flow path of the areas of concentrated anomalies are marked as areas affected by heat. The area with concentrated anomalies is designated as the target zone, and the area affected by heat is designated as the adjacent zone. The risk status is obtained based on the degree of thermal anomaly in the target zone and the heat change trend in the adjacent zones.

[0010] As a preferred embodiment of the collaborative optimization method for the fire extinguishing system and liquid cooling system of the energy storage power station described in this invention, the specific steps for obtaining the medium scheduling result are as follows: Based on the risk status, the degree of thermal anomaly in the target zone is correlated with the thermal change trend of adjacent zones to determine the zone's treatment level. Based on the zoning treatment level, combined with the liquid cooling available path, fire protection available path and media status results, the working mode of the liquid cooling fire protection common flow channel corresponding to the target zone is identified to obtain the flow channel mode result. When the flow channel mode result is liquid cooling circulation mode, liquid cooling circulation scheduling is performed on the common cooling fire extinguishing medium, and the common cooling fire extinguishing medium is allocated to the liquid cooling available path corresponding to the target zone. When the flow channel mode result is the fire injection mode, fire injection scheduling is performed on the common cooling fire extinguishing medium, and the common cooling fire extinguishing medium is allocated to the fire available path corresponding to the target zone. Based on the heating change trend of adjacent zones, protective liquid cooling scheduling is performed on the liquid cooling available paths corresponding to adjacent zones. The flow channel pattern results, liquid cooling circulation scheduling, fire injection scheduling and protective liquid cooling scheduling are combined to obtain the medium scheduling results.

[0011] As a preferred embodiment of the collaborative optimization method for the fire extinguishing system and liquid cooling system of the energy storage power station described in this invention, the specific steps of controlling the liquid cooling fire-fighting common flow channel corresponding to the target zone to enter the corresponding working state according to the medium scheduling result are as follows: When the flow channel mode result is the fire injection mode, the fire injection scheduling information is extracted from the medium scheduling result. The target zone is used as the associated object, and the fire injection scheduling information is written into the fire available path corresponding to the target zone and used as the injection switching path. Close the return liquid channel related to liquid cooling circulation return in the liquid injection switching path, and open the injection channel related to fire-fighting liquid injection in the liquid injection switching path to obtain the target flow channel status; According to the target flow channel status, the common cooling and extinguishing medium is switched from the liquid cooling circulation direction to the fire injection direction to obtain the target injection state. The liquid-cooled fire common flow channel in the target injection state is marked as the fire injection state.

[0012] As a preferred embodiment of the collaborative optimization method for the fire extinguishing system and liquid cooling system of the energy storage power station described in this invention, the liquid cooling fire extinguishing shared flow channel corresponding to adjacent zones is kept in liquid cooling circulation state to obtain a liquid cooling fire extinguishing collaborative control strategy. The specific steps are as follows: Extract the protective liquid cooling scheduling information corresponding to adjacent partitions from the media scheduling results. Using adjacent partitions as the associated objects, write the protective liquid cooling scheduling information into the liquid cooling available path corresponding to the adjacent partitions and keep it as a loop path. Based on the partitioned flow path, the overlapping paths between the circulation holding path and the liquid injection switching path are isolated and controlled, and the liquid supply channel and liquid return channel in the circulation holding path are opened to obtain the status of adjacent flow paths. Based on the adjacent flow channel status, the shared cooling extinguishing medium is controlled to maintain the liquid cooling circulation direction in adjacent zones to obtain the adjacent liquid cooling status. The target liquid injection status and the adjacent liquid cooling status are synchronized and arranged to generate a liquid cooling fire protection collaborative control strategy.

[0013] As a preferred embodiment of the collaborative optimization method for the fire extinguishing system and liquid cooling system of the energy storage power station described in this invention, the specific steps of executing the injection of the common cooling extinguishing medium in the target zone and the protective liquid cooling control of adjacent zones according to the liquid cooling fire extinguishing collaborative control strategy are as follows: Based on the liquid-cooled fire-fighting collaborative control strategy, the injection channel is opened, and the common cooling fire-extinguishing medium is controlled to enter the target zone according to the target injection state to obtain the target injection execution state; According to the liquid-cooled fire-fighting collaborative control strategy, the supply and return channels corresponding to the circulation path are kept connected, and the shared cooling and extinguishing medium is circulated in adjacent zones according to the adjacent liquid-cooled status to obtain the adjacent liquid-cooled execution status. The execution status of the target injection and the execution status of adjacent liquid cooling are jointly verified, and the changes in the handling of the target partition and the changes in the protection of adjacent partitions are collected to obtain execution feedback data.

[0014] As a preferred embodiment of the collaborative optimization method for the fire extinguishing system and liquid cooling system of the energy storage power station described in this invention, the steps for obtaining collaborative optimization control parameters by modifying the shared cooling fire extinguishing medium scheduling conditions and the liquid cooling fire-fighting shared flow channel switching conditions are as follows: The execution feedback data is partitioned and assigned, and the disposal changes corresponding to the target partition are taken as the target feedback data, and the protection changes corresponding to the adjacent partitions are taken as the adjacent feedback data. When the target feedback data indicates that the change in the handling of the target zone has not met the preset handling requirements, calculate the fire injection maintenance time and write the fire injection maintenance time into the common cooling extinguishing medium dispatch conditions. When the adjacent feedback data indicates that the protection changes of the adjacent zones have not met the preset protection requirements, the liquid cooling cycle holding time is calculated and written into the liquid cooling fire protection common flow channel switching conditions to obtain the collaborative optimization control parameters.

[0015] Secondly, this invention provides a collaborative optimization system for a fire suppression system and a liquid cooling system in an energy storage power station, comprising: a collaborative monitoring data generation module for collecting operational data of the energy storage power station and data of the shared liquid cooling fire suppression channel, and performing time synchronization and zonal association to obtain collaborative monitoring data; a zonal collaborative status data module for matching the correspondence between the monitoring zonals and the shared liquid cooling fire suppression channel in the collaborative monitoring data, and determining the liquid cooling usage status and fire suppression usage status of the shared cooling fire suppression medium to obtain zonal collaborative status data; a risk status module for identifying the risk of thermal anomalies in each monitoring zonal based on the zonal collaborative status data, and marking the anomaly concentration area and the heat-affected area as the target zonal and adjacent zonals respectively to obtain the risk status; and a medium scheduling module. The module is used to identify the working mode of the shared liquid-cooled fire extinguishing medium based on the risk status, and to perform liquid-cooled circulation scheduling and fire injection scheduling of the shared cooling extinguishing medium to obtain the medium scheduling result; the liquid-cooled fire extinguishing collaborative control strategy module is used to control the liquid-cooled fire extinguishing medium corresponding to the target zone to enter the corresponding working state according to the medium scheduling result, and to control the liquid-cooled fire extinguishing medium corresponding to the adjacent zone to maintain the liquid-cooled circulation state, to obtain the liquid-cooled fire extinguishing collaborative control strategy; the collaborative optimization control module is used to execute the injection of shared cooling extinguishing medium in the target zone and the protective liquid cooling control in the adjacent zone according to the liquid-cooled fire extinguishing collaborative control strategy, collect execution feedback data, and correct the shared cooling extinguishing medium scheduling conditions and the liquid-cooled fire extinguishing medium switching conditions in real time to obtain the collaborative optimization control parameters.

[0016] The beneficial effects of this invention are as follows: by synchronously arranging the injection switching path of the target zone and the circulation maintenance path of adjacent zones based on the media scheduling results, the coordinated control of the fire-fighting injection state and the protective liquid cooling state in the common flow channel is realized, so that the target zone can obtain continuous fire-fighting media injection, while adjacent zones maintain liquid cooling circulation protection to suppress the spread of thermal anomalies to the surrounding area and maintain the thermal stability of the zone, ultimately improving the continuous control capability and safety coordination capability of the energy storage power station in the abnormal handling process.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Reference Figures 1-4 As an embodiment of the present invention, this embodiment provides a method for the coordinated optimization of a fire extinguishing system and a liquid cooling system in an energy storage power station, comprising the following steps: S1. Collect operating data of the energy storage power station and data of the liquid-cooled fire protection shared flow channel, and perform time synchronization and zone association to obtain collaborative monitoring data.

[0026] S1.1. Collect the operating data of the energy storage power station and the liquid-cooled fire protection shared channel data. Time-align the operating data of the energy storage power station and the liquid-cooled fire protection shared channel data according to the collection time. Then, remove abnormal data and fill in missing data after time alignment to obtain synchronous monitoring data.

[0027] Specifically, when collecting energy storage power station operation data and liquid-cooled fire protection shared channel data, the energy storage power station operation data corresponding to each monitoring zone and the liquid-cooled fire protection shared channel data associated with the same monitoring zone are acquired synchronously, and the collection time is recorded for the energy storage power station operation data and the liquid-cooled fire protection shared channel data; the energy storage power station operation data and the liquid-cooled fire protection shared channel data are sorted according to the collection time, and the energy storage power station operation data and the liquid-cooled fire protection shared channel data with the same collection time or adjacent collection time are grouped into the same time slice to form time-aligned data; Abnormal data is removed from the time-aligned data. Invalid content that exceeds the acquisition range, has duplicate acquisition time, or has an abnormal acquisition order is deleted. Missing data is supplemented by valid content from adjacent acquisition times within the same monitoring zone. This ensures that the energy storage power station operation data and the liquid-cooled fire protection shared flow channel data within the same time slice remain corresponding and complete, resulting in synchronous monitoring data.

[0028] S1.2. Based on the monitoring zone number, the liquid-cooled fire protection common channel number, and the installation correspondence between the liquid-cooled fire protection common channel and the monitoring zone, the synchronous monitoring data is partitioned and merged to obtain collaborative monitoring data.

[0029] Specifically, based on synchronous monitoring data, the monitoring zone number is used as the basis for zoning. The operating data of energy storage power stations belonging to the same monitoring zone number in the synchronous monitoring data are categorized into the corresponding monitoring zone. Then, the liquid-cooled fire-fighting common flow channel number is used as the basis for flow channel zoning. The liquid-cooled fire-fighting common flow channel data belonging to the same liquid-cooled fire-fighting common flow channel number in the synchronous monitoring data are categorized into the corresponding liquid-cooled fire-fighting common flow channel. According to the installation correspondence between the liquid-cooled fire-fighting common flow channel and the monitoring zone, the operating data of energy storage power stations in the corresponding monitoring zone are associated and merged with the liquid-cooled fire-fighting common flow channel data in the corresponding liquid-cooled fire-fighting common flow channel. Synchronous monitoring data with inconsistent monitoring zone numbers, liquid-cooled fire-fighting common flow channel numbers, and installation correspondence are excluded. This ensures that the operating status in the same monitoring zone and the status of the corresponding liquid-cooled fire-fighting common flow channel form a zone correspondence, resulting in collaborative monitoring data.

[0030] S2. Match the monitoring zones with the common flow channels of liquid-cooled fire extinguishing based on the collaborative monitoring data, and determine the liquid-cooled usage status and fire-fighting usage status of the common cooling and extinguishing medium to obtain the zone collaborative status data.

[0031] S2.1. Based on collaborative monitoring data, read the installation location of each monitoring zone and the connection location of the liquid-cooled fire protection common flow channel, merge the supply liquid path, return liquid path and fire injection liquid path corresponding to the same monitoring zone to obtain the zone flow channel path.

[0032] Specifically, based on collaborative monitoring data, and using the monitoring zone number and the liquid-cooled fire-fighting common flow channel number as the corresponding basis, the installation location of each monitoring zone and the connection location of the liquid-cooled fire-fighting common flow channel are obtained. The installation location of each monitoring zone comes from the energy storage power station operation data that has been merged into zones in the collaborative monitoring data, and the connection location of the liquid-cooled fire-fighting common flow channel comes from the liquid-cooled fire-fighting common flow channel data that has been merged into zones in the collaborative monitoring data. Then, according to the installation correspondence between the liquid-cooled fire-fighting common flow channel and the monitoring zone, the liquid supply path, liquid return path, and fire-fighting injection path that have a connection relationship with the same monitoring zone are grouped into the same monitoring zone, and the path contents that do not have an installation correspondence relationship or inconsistent connection locations with the same monitoring zone are excluded, so that the liquid supply path, liquid return path, and fire-fighting injection path corresponding to the same monitoring zone form a complete path set, and the zone flow channel path is obtained.

[0033] S2.2. Based on the zoned flow path, identify the continuity of supply and return liquid in the liquid cooling circulation state and mark the liquid cooling available path. Identify the directional liquid injection continuity in the zoned flow path in the fire-fighting liquid injection state and mark the fire-fighting available path.

[0034] Specifically, after obtaining the flow path of the zone, the starting and ending positions, connection direction and path closure status of the supply path and return path within the same monitoring zone are checked according to the merging results of the supply path, return path and fire injection path in the flow path of the zone. When the supply path can deliver the common cooling extinguishing medium to the corresponding monitoring zone, and the return path can guide the common cooling extinguishing medium from the corresponding monitoring zone back to the liquid-cooled fire-fighting common flow channel, and there is no disconnection, reverse connection, or occupation by the fire-fighting injection path between the supply path and the return path, the flow channel path of the corresponding zone is marked as a liquid-cooled usable path; then the starting position, injection direction, and end connection position of the fire-fighting injection path in the same monitoring zone are checked. When the fire-fighting injection path can directionally introduce the common cooling extinguishing medium from the liquid-cooled fire-fighting common flow channel into the corresponding monitoring zone, and the fire-fighting injection path does not rely on the return path to form a circulating return, the flow channel path of the corresponding zone is marked as a fire-fighting usable path.

[0035] It should be noted that the common cooling extinguishing medium is a water-based liquid medium that can be used as a cooling medium in liquid-cooled circulation mode and as an extinguishing medium in fire-fighting liquid injection mode. The common cooling extinguishing medium includes deionized water, low conductivity water-based coolant, or water-based coolant with flame-retardant and cooling effects.

[0036] S2.3. Based on the available liquid cooling path and the available fire protection path, the liquid cooling usage status and fire protection usage status of the shared cooling and extinguishing medium are divided into available status, restricted status and unavailable status to obtain the medium status results.

[0037] Specifically, the shared cooling extinguishing medium is matched with the liquid cooling available path of the corresponding monitoring zone. When the shared cooling extinguishing medium can be supplied and returned along the liquid cooling available path, the liquid cooling usage status of the shared cooling extinguishing medium is classified as available. When the return flow of liquid is restricted in the available liquid cooling path, the liquid cooling usage status of the shared cooling extinguishing medium is classified as a restricted state; when the available liquid cooling path is missing or the supply and return flow is interrupted, the liquid cooling usage status of the shared cooling extinguishing medium is classified as an unavailable state. Next, the shared cooling and extinguishing medium is matched with the available fire-fighting paths of the corresponding monitoring zones. When the shared cooling and extinguishing medium can be directed into the corresponding monitoring zone along the available fire-fighting paths, the fire-fighting usage status of the shared cooling and extinguishing medium is classified as available. When the available fire-fighting paths are partially connected but the directional injection is restricted, the fire-fighting usage status of the shared cooling and extinguishing medium is classified as restricted. When the available fire-fighting paths are missing or the directional injection is interrupted, the fire-fighting usage status of the shared cooling and extinguishing medium is classified as unavailable, thus obtaining the medium status result.

[0038] S2.4. Write the zone flow path, liquid cooling available path, fire protection available path, medium status results, and the zone thermal change status of the corresponding monitoring zone into the corresponding monitoring zone to obtain the zone collaborative status data.

[0039] Specifically, the corresponding monitoring zone is used as the writing object, and the flow path of the zone is written into the corresponding monitoring zone to represent the belonging relationship between the liquid supply path, liquid return path and fire injection path in the corresponding monitoring zone. The available liquid cooling paths and fire-fighting paths are written into the corresponding monitoring zones to characterize the path availability of the corresponding monitoring zones under liquid cooling circulation and fire-fighting injection conditions; the media status results are written into the corresponding monitoring zones to characterize the liquid cooling and fire-fighting usage status of the shared cooling and extinguishing media within the corresponding monitoring zones. The thermal change status of the corresponding monitoring zone is written into the corresponding monitoring zone by the operation data of the energy storage power station in the collaborative monitoring data. This is used to characterize the thermal change of the corresponding monitoring zone and form the collaborative status data of the zone, which simultaneously includes channel affiliation, path availability, medium availability and thermal change.

[0040] S3. Based on the partitioned collaborative status data, risk identification is performed on the thermal anomaly changes in each partition, and the areas with concentrated anomalies and areas affected by heat are marked as the target partition and adjacent partitions, respectively, to obtain the risk status.

[0041] S3.1. Based on the partitioned collaborative status data, the partitioned thermal change status of each monitoring partition is compared with the preset normal thermal status to obtain the degree of partitioned thermal anomaly.

[0042] Specifically, taking each monitoring zone as the processing object, the thermal change status of the zone in the zone collaborative status data is compared with the normal thermal status of the corresponding monitoring zone to obtain the thermal deviation of the zone thermal change status relative to the normal thermal status. The normal thermal status comes from the energy storage power station operation data collected during the normal operation of the energy storage power station and is used to represent the allowable thermal change reference range of the corresponding monitoring zone under normal operation. The thermal deviation is compared with the thermal anomaly threshold, which is derived from the operating data of the energy storage power station collected during normal operation. When the thermal deviation does not reach the thermal anomaly threshold, the corresponding monitoring zone is marked as a normal thermal change state. When the thermal deviation reaches the thermal anomaly threshold, the corresponding monitoring zone is marked as a thermal anomaly state. When the thermal deviation reaches the preset thermal anomaly threshold and shows an increasing trend in adjacent collection time, the corresponding monitoring zone is marked as a continuous thermal anomaly state, thus obtaining the degree of thermal anomaly in the zone.

[0043] It should be noted that the thermal anomaly threshold is derived from the operating data of the energy storage power station collected during normal operation. The thermal change status of each monitoring zone under normal operating conditions is extracted, and the thermal change status of the zone is compared with the normal thermal status of the corresponding monitoring zone to obtain the normal thermal deviation record. The effective fluctuations caused by changes in charging and discharging conditions in the normal thermal deviation record are retained, and the invalid fluctuations caused by abnormal collection are removed. Based on the processed normal thermal deviation record, the maximum allowable thermal deviation range of the corresponding monitoring zone under normal operating conditions is obtained, and the maximum thermal deviation range is used as the thermal anomaly threshold of the corresponding monitoring zone.

[0044] S3.2. Based on the degree of thermal anomaly in each zone, and combined with the available liquid cooling paths, the thermal anomaly suppression status of each monitoring zone is identified, and the monitoring zones where the degree of thermal anomaly continues to increase and the thermal anomaly suppression status decreases are marked as anomaly concentration areas.

[0045] Specifically, the degree of thermal anomaly in the zone during the continuous acquisition time is compared before and after, and the thermal anomaly suppression is judged in combination with the available liquid cooling path of the corresponding monitoring zone. When there is an available liquid cooling path in the corresponding monitoring zone, and the degree of thermal anomaly in the zone changes from a normal thermal change state to a thermal anomaly state, or from a thermal anomaly state to a continuous thermal anomaly state, it indicates that the available liquid cooling path has failed to suppress the increase in the degree of thermal anomaly in the zone, and the thermal anomaly suppression of the corresponding monitoring zone is marked as a decrease. When there is no available liquid cooling path for the corresponding monitoring zone, and the thermal anomaly level of the zone is in a thermal anomaly state or a continuous thermal anomaly state, it indicates that the corresponding monitoring zone lacks liquid cooling suppression conditions, and the thermal anomaly suppression status of the corresponding monitoring zone is also marked as decreasing; monitoring zones marked as decreasing in thermal anomaly suppression status and whose thermal anomaly level continues to rise during continuous acquisition time are marked as anomaly concentration areas.

[0046] S3.3. Based on the abnormal concentration area, identify the heating change trend of the monitoring zone around the abnormal concentration area, and in combination with the flow path of the zone, mark the surrounding monitoring zone that has a heating change trend and is associated with the flow path of the abnormal concentration area as the heating affected area.

[0047] Specifically, taking the area of ​​concentrated anomalies as the center, the surrounding monitoring zones adjacent to the area of ​​concentrated anomalies are selected according to the installation location of each monitoring zone in the collaborative monitoring data, and the thermal change status of the surrounding monitoring zones during the continuous acquisition time is compared before and after. When the thermal change state of the surrounding monitoring zone changes from a normal thermal change state to a thermal anomaly state, or when the thermal deviation of the surrounding monitoring zone shows an increasing trend during the continuous acquisition time, it is determined that the surrounding monitoring zone has a thermal change trend. The surrounding monitoring zones with heat change trends are checked against the flow paths of the zones. If the surrounding monitoring zones and the abnormal concentration areas share the same liquid supply path, liquid return path, or fire injection path in the flow paths of the zones, or if the surrounding monitoring zones and the abnormal concentration areas are respectively connected to the same liquid-cooled fire-fighting shared flow path, then it is determined that there is a flow path association between the surrounding monitoring zones and the abnormal concentration areas. The surrounding monitoring zones that simultaneously meet the conditions of having heat change trends and having flow path associations are marked as heat-affected areas.

[0048] S3.4. Take the area with concentrated anomalies as the target zone and the area affected by heat as the adjacent zone. Based on the degree of thermal anomaly in the target zone and the trend of heat change in the adjacent zones, obtain the risk status.

[0049] Specifically, the area with concentrated anomalies is designated as the target zone, the area affected by heat is designated as the adjacent zone, the target zone is designated as the main risk object, and the adjacent zone is designated as the object of diffusion and impact. The degree of thermal anomaly in the target zone and the trend of thermal change in the adjacent zone are organized accordingly. When the target zone is in a thermal anomaly state or a continuous thermal anomaly state, and the adjacent zone has a trend of thermal change, the target zone and the adjacent zone are written into the risk status together. When the target zone is in a thermal anomaly state or a continuous thermal anomaly state, but no adjacent zones are marked, the target zone is written into the risk status separately to obtain the risk status for subsequent identification of the working mode of the liquid-cooled fire protection shared flow channel.

[0050] S4. Based on the risk status, identify the working mode of the shared liquid-cooled fire extinguishing channel, and perform liquid-cooled circulation scheduling and fire injection scheduling for the shared cooling extinguishing medium to obtain the medium scheduling results.

[0051] S4.1. Based on the risk status, the degree of thermal anomaly in the target partition is correlated with the thermal change trend of adjacent partitions to determine the partition handling level.

[0052] Specifically, the target zone and adjacent zones in the risk state are the processing objects. The degree of thermal anomaly of the target zone is used as the main judgment criterion, and the thermal change trend of adjacent zones is used as the diffusion judgment criterion. When the thermal anomaly level of the target partition is in a thermal anomaly state, and the risk status does not include adjacent partitions with a trend of thermal change, it indicates that the thermal anomaly of the target partition is still in a stage that can be suppressed by liquid cooling circulation, and the target partition is classified into the liquid cooling circulation treatment level. When the thermal anomaly level of the target zone is a continuous thermal anomaly state, or when the risk state includes adjacent zones with a trend of thermal change, it indicates that the thermal anomaly of the target zone has a trend of continuous aggravation or spread to the surrounding area. The target zone is then classified into a fire-fighting liquid injection treatment level. The liquid cooling circulation treatment level or the fire-fighting liquid injection treatment level is used as the corresponding zone treatment level for the target zone to obtain the zone treatment level.

[0053] S4.2. Based on the zoning treatment level, combined with the available liquid cooling path, available fire protection path and media status results, the working mode of the liquid cooling fire protection common flow channel corresponding to the target zone is identified to obtain the flow channel mode result.

[0054] Specifically, the zoning treatment level is matched with the liquid cooling available path, fire protection available path and media status result corresponding to the target zoning. When the zoning treatment level is the liquid cooling circulation treatment level, and there is a liquid cooling available path in the target zoning, and the liquid cooling usage status in the media status result is available or restricted, the liquid cooling fire protection common flow channel corresponding to the target zoning is identified as liquid cooling circulation mode. When the zoning treatment level is fire-fighting liquid injection treatment level, and there is a fire-fighting available path in the target zoning, and the fire-fighting usage status in the medium status result is available or restricted, the liquid-cooled fire-fighting common flow channel corresponding to the target zoning will be identified as fire-fighting liquid injection mode. When the zoning treatment level is fire injection treatment level but the fire available path is missing, or the fire use status in the medium status result is unavailable, the liquid-cooled fire common flow channel corresponding to the target zoning will not enter the fire injection mode for the time being, and the liquid-cooled available path corresponding to the target zoning will be retained for liquid-cooled circulation control; the liquid-cooled circulation mode or fire injection mode will be used as the flow channel mode result corresponding to the target zoning.

[0055] S4.3. When the flow channel mode result is liquid cooling circulation mode, liquid cooling circulation scheduling is performed on the common cooling extinguishing medium, and the common cooling extinguishing medium is allocated to the liquid cooling available path corresponding to the target zone.

[0056] Specifically, when the flow channel mode result is liquid cooling circulation mode, the liquid cooling available path corresponding to the target partition is used as the scheduling object, the liquid supply path and liquid return path in the liquid cooling available path are kept in a connected state, and the fire injection path corresponding to the target partition is kept from participating in the injection. The shared cooling extinguishing medium is introduced into the target zone along the liquid supply path corresponding to the target zone, and then the shared cooling extinguishing medium after passing through the target zone is guided back to the liquid-cooled fire-fighting common flow channel along the liquid return path corresponding to the target zone, so that the shared cooling extinguishing medium forms a liquid-cooled circulation flow direction within the target zone; after the liquid-cooled circulation flow direction is formed, the thermal anomaly degree of the target zone is continuously suppressed, and the shared cooling extinguishing medium is distributed to the liquid-cooled available path corresponding to the target zone, thus completing the liquid-cooled circulation scheduling of the shared cooling extinguishing medium.

[0057] It should be noted that liquid cooling circulation scheduling refers to controlling the supply and return process of the common cooling extinguishing medium in the available liquid cooling path when the target zone can still suppress thermal anomalies through liquid cooling. This allows the common cooling extinguishing medium to enter the target zone along the supply path and then return to the common liquid cooling fire channel along the return path, thereby circulating and cooling the target zone.

[0058] S4.4. When the flow channel mode result is the fire injection mode, fire injection scheduling is performed on the common cooling fire extinguishing medium, and the common cooling fire extinguishing medium is allocated to the fire available path corresponding to the target zone.

[0059] Specifically, when the flow channel mode result is the fire injection mode, the fire available path corresponding to the target zone is used as the fire injection scheduling object, the return path in the liquid cooling available path corresponding to the target zone is isolated from the liquid cooling circulation state, and then the fire available path corresponding to the target zone is connected to the liquid cooling fire shared flow channel. Based on the continuity of directional liquid injection along the available fire-fighting paths, the common cooling extinguishing medium is controlled to enter the target zone from the liquid-cooled common fire-fighting channel, and the common cooling extinguishing medium is kept flowing directionally towards the target zone along the available fire-fighting paths. During the directional flow, the target zone no longer performs the liquid-cooled circulation between the supply path and the return path. Instead, the available fire-fighting paths take on the function of injecting the common cooling extinguishing medium, distributing the common cooling extinguishing medium to the available fire-fighting paths corresponding to the target zone.

[0060] It should be noted that fire-fighting liquid injection scheduling refers to controlling the directional injection process of the common cooling extinguishing medium in the available fire-fighting path when the thermal anomaly in the target zone can no longer be suppressed by liquid cooling circulation alone. This prevents the common cooling extinguishing medium from flowing back in the liquid cooling circulation manner, but instead directs it into the target zone along the fire-fighting liquid injection path for liquid injection extinguishing and continuous cooling.

[0061] S4.5. Based on the heating change trend of adjacent zones, perform protective liquid cooling scheduling on the liquid cooling available paths corresponding to adjacent zones, and merge the flow channel mode results, liquid cooling circulation scheduling, fire injection scheduling and protective liquid cooling scheduling to obtain the medium scheduling results.

[0062] Specifically, the heating trend of adjacent zones is used as the basis for processing, and protective liquid cooling scheduling is carried out on the liquid cooling available paths corresponding to adjacent zones. When there is a trend of heat change in adjacent zones, the supply and return paths of the liquid cooling available paths in the adjacent zones are kept connected, and the shared cooling extinguishing medium is controlled to maintain the liquid cooling circulation direction in the adjacent zones, so that the adjacent zones can suppress the trend of heat change through liquid cooling circulation, and obtain the protective liquid cooling scheduling situation. The flow channel pattern results corresponding to the target zone, the liquid cooling circulation scheduling or fire-fighting liquid injection scheduling corresponding to the flow channel pattern results, and the protective liquid cooling scheduling corresponding to the adjacent zones are merged according to the target zone and the adjacent zones, so that the treatment method of the target zone and the protection method of the adjacent zones are corresponding, and the media scheduling results are obtained.

[0063] It should be noted that the liquid cooling circulation scheduling is used to characterize the circulation distribution of the shared cooling extinguishing medium in the available liquid cooling path when the target zone is in liquid cooling circulation mode. Firefighting fluid injection scheduling is used to characterize the directional injection of shared cooling extinguishing media into the available firefighting paths when the target zone is in firefighting fluid injection mode. The protective liquid cooling scheduling is used to characterize the protective circulation of shared cooling extinguishing media in the corresponding liquid cooling available paths of adjacent zones when there is a trend of heating change in adjacent zones.

[0064] S5. Based on the media scheduling results, control the liquid-cooled fire protection shared flow channel corresponding to the target zone to enter the corresponding working state, and when there are adjacent monitoring zones, control the liquid-cooled fire protection shared flow channel corresponding to the adjacent zone to maintain the liquid-cooled circulation state, thus obtaining the liquid-cooled fire protection collaborative control strategy.

[0065] S5.1. When the flow channel mode result is the fire injection mode, extract the fire injection scheduling information from the medium scheduling result, take the target zone as the associated object, write the fire injection scheduling information into the fire available path corresponding to the target zone, and use it as the injection switching path.

[0066] Specifically, when the flow channel mode result is the fire injection mode, the fire injection scheduling information corresponding to the target zone is extracted from the medium scheduling result, and the fire injection scheduling information is written into the fire available path corresponding to the target zone, with the target zone as the associated object. During the writing process, the injection direction, injection sequence and injection maintenance requirements in the fire injection scheduling information are respectively mapped to the starting connection position, path connection sequence and end import position in the fire available path, so that the fire injection scheduling information and the path used to import the common cooling extinguishing medium in the target zone form a one-to-one correspondence. The validity of the available fire-fighting paths after the fire-fighting liquid injection scheduling is verified. When the available fire-fighting paths can introduce the common cooling fire-fighting medium from the liquid-cooled fire-fighting common flow channel into the target zone according to the fire-fighting liquid injection scheduling, the available fire-fighting paths after the fire-fighting liquid injection scheduling are used as the injection switching paths, which are then used to control the liquid-cooled fire-fighting common flow channel corresponding to the target zone to switch from the liquid-cooled circulation direction to the fire-fighting liquid injection direction.

[0067] S5.2. Close the return liquid channel related to liquid cooling circulation return liquid in the liquid injection switching path, and open the injection channel related to fire-fighting liquid injection in the liquid injection switching path to obtain the target flow channel status.

[0068] Specifically, the return channels related to the liquid-cooled circulation return in the injection switching path are closed to prevent the common cooling extinguishing medium from returning to the common liquid-cooled fire-fighting flow channel along the return direction of the target zone, thus preventing the common cooling extinguishing medium from entering the liquid-cooled circulation return direction during fire-fighting injection. Then, the injection channels related to fire-fighting injection in the injection switching path are opened to connect the common liquid-cooled fire-fighting flow channel to the directional injection direction of the target zone, adjusting the flow direction of the common cooling extinguishing medium from the original liquid-cooled circulation direction to the fire-fighting injection direction. The status of the closure of the return channels and the opening of the injection channels are checked. When the return channels are closed and the injection channels are open, the common liquid-cooled fire-fighting flow channel corresponding to the target zone is recorded as the target flow channel status. The target flow channel status is used to indicate that the injection switching path has the flow channel conditions to inject fire-fighting fluid into the target zone.

[0069] S5.3. According to the target flow channel status, control the common cooling fire extinguishing medium to switch from the liquid cooling circulation direction to the fire injection direction to obtain the target injection state, and mark the liquid cooling fire common flow channel in the target injection state as the fire injection state.

[0070] Specifically, according to the channel status of the target flow channel, where the return liquid channel is closed and the injection liquid channel is open, first stop the common cooling fire extinguishing medium from participating in the liquid cooling circulation along the corresponding return liquid channel of the target zone, then control the common cooling fire extinguishing medium to enter the injection switching path, and flow from the liquid-cooled fire common flow channel to the target zone along the fire injection direction; During the process of the shared cooling fire extinguishing medium entering the injection switching path, it is checked whether the shared cooling fire extinguishing medium is still flowing back along the liquid cooling circulation direction, and it is checked whether the shared cooling fire extinguishing medium continuously enters the target zone along the fire injection direction. When the liquid cooling circulation direction is blocked and the fire-fighting injection direction remains connected, the directional injection state of the common cooling extinguishing medium in the target zone is taken as the target injection state, and the liquid-cooled fire-fighting common flow channel in the target injection state is marked as the fire-fighting injection state.

[0071] S5.4. Extract the protective liquid cooling scheduling information corresponding to adjacent partitions from the media scheduling results. Using adjacent partitions as the associated objects, write the protective liquid cooling scheduling information into the liquid cooling available path corresponding to the adjacent partitions and keep it as a loop path.

[0072] Specifically, the protective liquid cooling scheduling information corresponding to the adjacent zones is extracted from the media scheduling results, and the adjacent zones are used as the merging objects. The protective liquid cooling scheduling information is written into the liquid cooling available path corresponding to the adjacent zones. During the writing process, the protective liquid cooling scheduling information is mapped to the supply path and return path in the liquid cooling available path. The supply direction and return direction of the shared cooling extinguishing medium in the adjacent zones are retained, and the flow direction content that conflicts with the fire injection direction of the target zone is excluded. The available liquid cooling paths after the protective liquid cooling scheduling information is written are checked for connectivity. When the available liquid cooling paths can maintain the supply and return circulation of the shared cooling extinguishing medium in adjacent zones, the available liquid cooling paths after the protective liquid cooling scheduling information is written are used as circulation maintenance paths for subsequent control of the liquid cooling fire protection common flow channels corresponding to adjacent zones to maintain the liquid cooling circulation state.

[0073] S5.5. Based on the partitioned flow path, isolate and control the overlapping paths between the circulation holding path and the liquid injection switching path, and open the liquid supply channel and the liquid return channel in the circulation holding path to obtain the status of adjacent flow paths.

[0074] Specifically, based on the flow path of the zone, the path position of the circulation maintenance path and the liquid injection switching path is checked. The connected part that belongs to both the circulation maintenance path and the liquid injection switching path is used as the isolation control object, and the connected position in the circulation maintenance path leading to the liquid injection switching path is closed to block the common cooling extinguishing medium from the liquid cooling circulation direction of the adjacent zone to the fire injection direction of the target zone. Open the supply and return channels in the circulation path, ensuring that the shared cooling extinguishing medium enters the adjacent zone along the supply channel corresponding to the adjacent zone and returns to the liquid-cooled fire protection common flow channel along the return channel corresponding to the adjacent zone. After isolation control and channel opening, check the supply direction, return direction, and injection switching path direction in the circulation path. When the supply and return channels of the circulation path remain connected, and the connecting part between the circulation path and the injection switching path is in an isolated state, record the liquid-cooled fire protection common flow channel corresponding to the adjacent zone as the adjacent flow channel state.

[0075] S5.6. According to the adjacent flow channel status, control the shared cooling extinguishing medium to maintain the liquid cooling circulation direction in the adjacent zones, obtain the adjacent liquid cooling status, synchronize the target liquid injection status and the adjacent liquid cooling status, and generate a liquid cooling fire protection collaborative control strategy.

[0076] Specifically, according to the status of adjacent flow channels, the supply and return channels in the circulation path are kept in a connected state, and the common cooling extinguishing medium is controlled to enter the adjacent zone along the supply channel and then return to the liquid-cooled fire protection common flow channel along the return channel. At the same time, the isolation between the circulation path and the injection switching path is maintained to avoid the liquid-cooled circulation flow in the adjacent zone from interfering with the fire injection flow in the target zone. When the shared cooling extinguishing medium continuously circulates in adjacent zones according to the supply and return directions, and the liquid-cooled fire-fighting shared flow channel corresponding to the adjacent zone has not switched to the fire-fighting injection direction, the liquid-cooled fire-fighting shared flow channel corresponding to the adjacent zone is recorded as the adjacent liquid-cooled state; the target injection state and the adjacent liquid-cooled state are synchronously arranged according to the correspondence between the target zone and the adjacent zone, so that the target zone maintains the fire-fighting injection state and the adjacent zone maintains the liquid-cooled circulation state, thereby generating a liquid-cooled fire-fighting collaborative control strategy.

[0077] S6. Based on the liquid-cooled fire protection collaborative control strategy, execute the working status control corresponding to the target zone and the protective liquid-cooled control of adjacent zones, collect execution feedback data, and correct the shared cooling fire extinguishing medium scheduling conditions and the liquid-cooled fire protection shared flow channel switching conditions to obtain collaborative optimization control parameters.

[0078] S6.1. Based on the liquid-cooled fire-fighting collaborative control strategy, the injection channel is opened, and the shared cooling fire-extinguishing medium is controlled to enter the target zone according to the target injection state to obtain the target injection execution state.

[0079] Specifically, according to the target injection status of the target zone in the liquid-cooled fire-fighting collaborative control strategy, the injection channel in the injection switching path is opened, and the return channel related to the liquid-cooled circulation return is kept closed, so that the common cooling fire extinguishing medium no longer returns to the common liquid-cooled fire-fighting flow channel along the liquid-cooled circulation direction, but enters the target zone along the fire-fighting injection direction. During the process of the shared cooling extinguishing medium entering the target zone, the continuity of the flow of the shared cooling extinguishing medium in the injection switching path and the entry status in the target zone are checked according to the injection direction and injection maintenance requirements corresponding to the target injection state. When the shared cooling extinguishing medium continues to enter the target zone along the injection channel and the injection switching path has not restored the liquid cooling circulation return direction, the ongoing shared cooling extinguishing medium injection process in the target zone is recorded as the target injection execution status.

[0080] S6.2. In accordance with the liquid-cooled fire-fighting collaborative control strategy, the supply and return channels corresponding to the circulation path are kept connected, and the shared cooling and extinguishing medium is circulated in adjacent zones according to the adjacent liquid-cooled status to obtain the adjacent liquid-cooled execution status.

[0081] Specifically, according to the adjacent liquid cooling status corresponding to adjacent zones in the liquid cooling fire protection coordinated control strategy, the liquid supply channel and liquid return channel in the circulation maintenance path are kept in a connected state, and the isolation state between the circulation maintenance path and the liquid injection switching path is maintained. After the supply channel is connected, the common cooling extinguishing medium is controlled to enter the adjacent zone along the supply channel in the circulation maintenance path. After the return channel is connected, the common cooling extinguishing medium is controlled to return to the liquid-cooled fire-fighting common flow channel along the return channel in the circulation maintenance path, forming a continuous liquid-cooled circulation flow in the adjacent zone. During the circulation of the shared cooling extinguishing medium, the entry direction of the liquid supply channel, the return direction of the liquid return channel, and the isolation status between the circulation maintenance path and the injection switching path are checked. When the shared cooling extinguishing medium can maintain the liquid supply and return circulation in the adjacent zone, and the shared cooling extinguishing medium does not enter the fire injection direction corresponding to the target zone, the protective liquid cooling circulation process in the adjacent zone is recorded as the adjacent liquid cooling execution status.

[0082] S6.3. Perform collaborative verification of the target injection execution status and the adjacent liquid cooling execution status, and collect the handling changes of the target partition and the protection changes of the adjacent partitions to obtain execution feedback data.

[0083] Specifically, the target injection execution status and the adjacent liquid cooling execution status are checked together. First, it is checked whether the common cooling extinguishing medium in the target zone enters the target zone along the injection channel according to the target injection execution status. Then, it is checked whether the common cooling extinguishing medium in the adjacent zone maintains liquid cooling circulation along the supply channel and return channel according to the adjacent liquid cooling execution status. At the same time, it is checked whether the isolation status between the injection channel and the circulation path is maintained effectively. When there is no path occupancy conflict between the injection channel of the target zone and the circulation path of the adjacent zone, and the fire injection direction of the target zone does not affect the liquid cooling circulation direction of the adjacent zone, continue to collect the changes in the treatment of the target zone after the injection of the shared cooling extinguishing medium, and collect the changes in the protection of the adjacent zone after the protective liquid cooling control. The change in the handling of the target zone is used to represent the thermal anomaly changes of the target zone after fire injection, and the change in the protection of adjacent zones is used to represent the thermal changes of adjacent zones after liquid cooling circulation. The change in the handling of the target zone and the change in the protection of adjacent zones are organized according to the corresponding zones to obtain the execution feedback data.

[0084] S6.4. Perform partitioning and attribution processing on the execution feedback data, taking the disposal changes corresponding to the target partition as the target feedback data, and taking the protection changes corresponding to the adjacent partitions as the adjacent feedback data.

[0085] Specifically, taking the target partition and adjacent partitions as the belonging objects, the handling changes of the target partition in the execution feedback data are attributed to the target partition, and the protection changes of the adjacent partition in the execution feedback data are attributed to the adjacent partition. According to the correspondence between the target zone and adjacent zones in the liquid-cooled fire-fighting collaborative control strategy, the handling changes of the target zone and the target injection execution status are sorted out to reflect the thermal anomaly changes of the target zone after the injection of the common cooling fire extinguishing medium, and the handling changes corresponding to the target zone are used as target feedback data. The protection changes of adjacent zones are correlated with the adjacent liquid cooling execution status to reflect the heat changes of adjacent zones after protective liquid cooling control, and the protection changes corresponding to adjacent zones are used as adjacent feedback data.

[0086] S6.5. When the target feedback data indicates that the change in the treatment of the target zone does not meet the preset treatment requirements, calculate the fire injection maintenance time and write the fire injection maintenance time into the common cooling extinguishing medium scheduling conditions. When the adjacent feedback data indicates that the change in the protection of the adjacent zone does not meet the preset protection requirements, calculate the liquid cooling circulation maintenance time and write the liquid cooling circulation maintenance time into the liquid cooling fire common flow channel switching conditions to obtain the collaborative optimization control parameters.

[0087] Specifically, the changes in the response data in the target feedback data are compared with the response requirements. When the target feedback data indicates that the target zone is still in a thermal anomaly state or a continuous thermal anomaly state, or the response changes in the target zone have not fallen back to the range corresponding to the response requirements, the fire injection maintenance time of the target zone is calculated based on the difference between the thermal deviation corresponding to the target feedback data and the thermal anomaly threshold corresponding to the target zone, and the fire injection maintenance time is written into the common cooling extinguishing medium dispatch conditions. The protection changes in the adjacent feedback data are compared with the protection requirements. When the adjacent feedback data indicates that the adjacent zone still has a trend of heat change, or the protection change of the adjacent zone has not fallen back to the range corresponding to the protection requirements, the liquid cooling cycle maintenance time of the adjacent zone is calculated according to the heat change trend corresponding to the adjacent feedback data, and the liquid cooling cycle maintenance time is written into the liquid cooling fire common flow channel switching condition. The common cooling fire extinguishing medium scheduling condition after writing the fire injection maintenance time and the liquid cooling fire common flow channel switching condition after writing the liquid cooling cycle maintenance time are used together as the collaborative optimization control parameters.

[0088] It should be noted that the handling requirements are the operating data of the energy storage power station and historical thermal anomaly handling records collected during the normal operation of the energy storage power station, used to characterize the thermal anomaly reduction requirements that the target zone needs to achieve after the injection of the shared cooling and extinguishing medium; the protection requirements are the operating data of the energy storage power station and historical protective liquid cooling control records collected during the normal operation of the energy storage power station, used to characterize the thermal change suppression requirements that adjacent zones need to achieve after protective liquid cooling control.

[0089] It should also be noted that the modification to the fire-fighting fluid injection maintenance requirement can be expressed as: ; in, Indicates the first Duration of fire-fighting fluid injection for each target zone Indicates the first Basic fire-fighting fluid injection time for each target zone Indicates the first Thermal deviation in the target feedback data corresponding to each target partition Indicates the first The thermal anomaly threshold (with the same dimensions as the thermal deviation) corresponds to each target partition. This indicates the correction factor for the duration of fire-fighting fluid injection (extracted from historical thermal anomaly handling records). Indicates the target partition number.

[0090] The correction relationship for fire-fighting fluid injection maintenance requirements is expressed as follows: ; in, Indicates the first The duration of liquid cooling cycle maintenance after correction for adjacent zones Indicates the first Duration of liquid cooling cycle before correction of adjacent partitions Indicates the adjacent partition numbers, This represents the correction factor for the liquid cooling cycle duration (extracted from historical protective liquid cooling control records). Indicates the first The normalized heating trend in the adjacent feedback data corresponding to each adjacent partition.

[0091] This embodiment also provides a collaborative optimization system for a fire suppression system and a liquid cooling system in an energy storage power station, including: a collaborative monitoring data generation module, used to collect operating data of the energy storage power station and data of the shared liquid cooling fire suppression channel, and to perform time synchronization and zonal association to obtain collaborative monitoring data; a zonal collaborative status data module, used to match the collaborative monitoring data with the correspondence between the monitoring zonals and the shared liquid cooling fire suppression channel, and to determine the liquid cooling usage status and fire suppression usage status of the shared cooling fire suppression medium to obtain zonal collaborative status data; a risk status module, used to identify the risk of thermal anomalies in each monitoring zonal based on the zonal collaborative status data, and to mark the anomaly concentration area and the heat-affected area as the target zonal and adjacent zonal, respectively, to obtain the risk status; and a media scheduling module. The system is used to identify the working mode of the shared liquid-cooled fire extinguishing medium based on the risk status, and to perform liquid-cooled circulation scheduling and fire injection scheduling of the shared cooling extinguishing medium to obtain the medium scheduling result; the liquid-cooled fire extinguishing collaborative control strategy module is used to control the liquid-cooled fire extinguishing medium corresponding to the target zone to enter the corresponding working state according to the medium scheduling result, and to control the liquid-cooled fire extinguishing medium corresponding to the adjacent zone to maintain the liquid-cooled circulation state, to obtain the liquid-cooled fire extinguishing collaborative control strategy; the collaborative optimization control module is used to execute the injection of shared cooling extinguishing medium in the target zone and the protective liquid cooling control in the adjacent zone according to the liquid-cooled fire extinguishing collaborative control strategy, collect execution feedback data, and correct the shared cooling extinguishing medium scheduling conditions and the liquid-cooled fire extinguishing medium switching conditions in real time to obtain the collaborative optimization control parameters.

[0092] In summary, this invention achieves coordinated control of fire-fighting liquid injection status and protective liquid cooling status in a shared flow channel by simultaneously arranging the liquid injection switching path of the target zone and the circulation maintenance path of adjacent zones based on the media scheduling results. This enables the target zone to receive continuous fire-fighting media injection, while adjacent zones maintain liquid cooling circulation protection to suppress the spread of thermal anomalies to the surrounding area and maintain the thermal stability of the zones. Ultimately, this improves the continuous control capability and safety coordination capability of the energy storage power station during anomaly handling.

The method for coordinated optimization of the fire extinguishing system and liquid cooling system of an energy storage power station as described in claim 8, characterized in that, The modified shared cooling extinguishing medium scheduling conditions and liquid-cooled fire-fighting shared flow channel switching conditions are used to obtain collaborative optimization control parameters. The specific steps are as follows: The execution feedback data is partitioned and assigned, and the disposal changes corresponding to the target partition are taken as the target feedback data, and the protection changes corresponding to the adjacent partitions are taken as the adjacent feedback data. When the target feedback data indicates that the change in the handling of the target zone has not met the preset handling requirements, calculate the fire injection maintenance time and write the fire injection maintenance time into the common cooling extinguishing medium dispatch conditions. When the adjacent feedback data indicates that the protection changes of the adjacent zones have not met the preset protection requirements, the liquid cooling cycle holding time is calculated and written into the liquid cooling fire protection common flow channel switching conditions to obtain the collaborative optimization control parameters.

The risk status module is used to identify the risk of thermal anomalies in each monitoring zone based on the zone collaborative status data, and to mark the areas of concentrated anomalies and areas affected by heat as the target zone and adjacent zones, respectively, to obtain the risk status. The media scheduling module is used to identify the working mode of the common flow channel for liquid-cooled fire extinguishing based on the risk status, and to perform liquid-cooled circulation scheduling and fire injection scheduling for the common cooling and extinguishing media to obtain the media scheduling results. The liquid-cooled fire protection collaborative control strategy module is used to control the liquid-cooled fire protection common flow channel corresponding to the target zone to enter the corresponding working state according to the media scheduling result, and to control the liquid-cooled fire protection common flow channel corresponding to the adjacent zone to maintain the liquid-cooled circulation state, so as to obtain the liquid-cooled fire protection collaborative control strategy. The collaborative optimization control module is used to execute the injection of common cooling extinguishing medium in the target zone and the protective liquid cooling control of adjacent zones according to the liquid-cooled fire protection collaborative control strategy. It collects execution feedback data and corrects the scheduling conditions of common cooling extinguishing medium and the switching conditions of common liquid-cooled fire protection channels in real time to obtain collaborative optimization control parameters.
