Description

Technical Field

[0001] This disclosure relates to the field of energy storage power station control technology, and in particular to an emergency stop control method, system and storage medium for an energy storage power station. Background Technology

[0002] Emergency shutdown of an energy storage power station refers to the rapid disconnection of the energy storage system in the event of an emergency to protect the safety of equipment and personnel, while preventing the fault from escalating or causing a greater impact on the power grid. The above-mentioned emergency shutdown operation is usually executed in coordination by automatic protection systems and manual triggering, thereby achieving effective protection for the safe operation of the energy storage power station.

[0003] In existing emergency shutdown schemes for energy storage power stations, simple centralized hard-wired connections or complete reliance on software communication are often employed. For example, all emergency push buttons (EMPB) are typically connected in series or parallel to a single main control loop, ultimately managed and controlled globally through a central safety controller. If this central safety controller fails or communication is interrupted, the entire emergency shutdown scheme can malfunction, posing a significant safety hazard to the entire energy storage power station. Furthermore, the emergency shutdown control of individual energy storage units (e.g., individual energy storage containers) is disconnected from the overall emergency shutdown of the power station, failing to consider emergency shutdown control strategies holistically from the perspective of the overall safe operation of the energy storage power station. Summary of the Invention

[0004] The purpose of this disclosure is to provide an emergency stop control method, system, and storage medium for an energy storage power station. When any emergency stop control button in the energy storage power station is triggered, local shutdown control can be executed immediately, and the generated emergency stop control event can be used to determine whether there are other areas in the energy storage power station that require emergency stop protection, thereby effectively improving the overall safety of the energy storage power station.

[0005] To address the aforementioned technical problems, the first aspect of this disclosure provides an emergency stop control method for an energy storage power station, which may specifically include: when the emergency stop control button of the energy storage power station is triggered, controlling the energy storage power station facilities within the emergency stop control range of the triggered emergency stop control button to shut down urgently, and generating an emergency stop control event; determining the corresponding emergency stop protection range based on the emergency stop control event and the real-time operating status of the energy storage power station; and controlling the energy storage power station facilities within the emergency stop protection range to shut down urgently when the emergency stop protection range is larger than the emergency stop control range.

[0006] In one possible implementation of the first aspect above, determining the corresponding emergency stop protection range based on the emergency stop control event and the real-time operation status of the energy storage power station includes: synchronizing the emergency stop control event to the station-side emergency stop controller of the energy storage power station based on at least two redundant transmission links, wherein the station-side emergency stop controller is used to control the emergency shutdown of all energy storage power station facilities; and determining the first protection range corresponding to the emergency stop control event based on the matching between the real-time operation status of the energy storage power station and the emergency stop control strategy preset by the station-side emergency stop controller, wherein the emergency stop protection range includes the first protection range.

[0007] In one possible implementation of the first aspect mentioned above, the real-time operation status of the energy storage power station includes real-time operating parameter information of all energy storage power station facilities and / or real-time environmental information of the energy storage power station.

[0008] In one possible implementation of the first aspect above, when the triggered emergency stop control button has an upper-level emergency stop controller, the corresponding emergency stop protection range is determined based on the emergency stop control event and the real-time operation status of the energy storage power station. This includes: synchronizing the emergency stop control event to the upper-level emergency stop controller based on at least two redundant transmission links, wherein the upper-level emergency stop controller is associated with all emergency stop control buttons within a preset geographical area; and determining a second protection range corresponding to the emergency stop control event based on the matching between the real-time operation status of the energy storage power station within the preset geographical area and the preset emergency stop control strategy of the upper-level emergency stop controller, wherein the emergency stop protection range includes the second protection range.

[0009] In one possible implementation of the first aspect above, when the emergency stop control button is associated with at least one energy storage unit of the energy storage power station, the upper-level emergency stop controller is used to control the emergency shutdown of all energy storage units within a preset geographical area; the real-time operating status within the preset geographical area includes real-time operating parameter information of all energy storage units within the preset geographical area.

[0010] In one possible implementation of the first aspect above, controlling the emergency shutdown of the energy storage power station facility within the emergency stop control range of the triggered emergency stop control button includes: controlling a circuit breaker connected to the triggered emergency stop control button to perform a circuit breaking operation; and / or controlling the portion of the power conversion system of the energy storage power station located within the emergency stop control range to perform a shutdown operation.

[0011] In one possible implementation of the first aspect above, when the emergency stop protection range is larger than the emergency stop control range, controlling the emergency shutdown of the energy storage power station facilities within the emergency stop protection range includes: determining the energy storage power station facilities within the emergency stop protection range that have not been shut down in an emergency, based on the difference between the emergency stop protection range and the emergency stop control range, and determining the emergency stop controller corresponding to the energy storage power station facilities within the emergency stop protection range that have not been shut down in an emergency; and issuing an emergency stop control command to the emergency stop controller to control the emergency shutdown of the energy storage power station facilities within the emergency stop protection range that have not been shut down in an emergency.

[0012] In one possible implementation of the first aspect above, the emergency stop control method for such energy storage power station further includes: acquiring a fire alarm generated by the whole-station fire protection system of the energy storage power station; controlling the emergency shutdown of the energy storage power station facilities within the coverage area of ​​the fire alarm based on the fire alarm; or controlling the emergency shutdown of all energy storage power station facilities.

[0013] The second aspect of this disclosure provides an emergency stop control system for an energy storage power station, which may specifically include: an emergency stop control unit, used to control the emergency stop facilities within the emergency stop control range of the triggered emergency stop control button to shut down urgently when the emergency stop control button of the energy storage power station is triggered, and to generate an emergency stop control event; an emergency stop protection unit, used to determine the corresponding emergency stop protection range based on the emergency stop control event and the real-time operating status of the energy storage power station; the emergency stop control unit is also used to control the emergency stop of the energy storage power station facilities within the emergency stop protection range when the emergency stop protection range is greater than the emergency stop control range.

[0014] A third aspect of this disclosure provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the steps of the emergency stop control method for the energy storage power station provided in the first aspect.

[0015] The technical solution provided in this disclosure enables immediate local shutdown control when any emergency stop control button in the energy storage power station is triggered. Based on the generated emergency stop control event, it determines whether there are other areas in the energy storage power station requiring emergency stop protection, effectively improving the overall safety of the energy storage power station. Furthermore, in this technical solution, when the emergency stop control button is triggered, the generated emergency stop control event is synchronized to the station and the upper-level emergency stop controller via redundant transmission. Based on the preset emergency stop control strategy and the actual operating conditions of the energy storage power station, a precise and reasonable emergency stop protection range can be determined. This allows for rapid and effective local isolation in the event of an emergency fault, preventing the escalation of abnormal situations and maximizing the overall operational safety of the energy storage power station.

Detailed Implementation

[0018] In existing emergency shutdown schemes for energy storage power stations, simple centralized hard-wired connections or complete reliance on software communication are often employed. For example, all emergency stop control buttons are typically connected in series or parallel to a single main control loop, ultimately managed and controlled globally through a central safety controller. If this central safety controller fails or communication is interrupted, the entire emergency shutdown scheme can malfunction, posing a significant safety hazard to the energy storage power station. To address these technical problems, some embodiments of this disclosure provide an emergency stop control method, system, and storage medium for energy storage power stations. This method enables immediate local shutdown control when any emergency stop control button in the energy storage power station is triggered, and determines whether other areas requiring emergency stop protection exist based on the generated emergency stop control event, effectively improving the overall safety of the energy storage power station.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the various embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details are provided in the embodiments of this disclosure to facilitate a better understanding of the disclosure. However, the technical solutions claimed in this disclosure can be implemented even without these technical details and various variations and modifications based on the following embodiments. The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of this disclosure. The various embodiments can be combined with and referenced by each other without contradiction.

[0020] In some embodiments of this disclosure, Figure 1 A flowchart illustrating an emergency stop control method for an energy storage power station is shown, as follows: Figure 1 As shown, process 100 may specifically include the following steps: Step 110: When the emergency stop control button of the energy storage power station is triggered, the energy storage power station facilities within the emergency stop control range of the triggered emergency stop control button are controlled to shut down urgently, and an emergency stop control event is generated. In some embodiments, the emergency stop control button of the energy storage power station can be a physical button or a virtual button; the emergency stop control button can be triggered based on the interactive operation of the operation and maintenance personnel (such as pressing, pressing, etc.), or it can be triggered based on the operation status monitoring system of the energy storage power station when some monitoring data of the energy storage power station is abnormal (such as when some operating states of the energy storage power station meet the abnormal emergency stop conditions, etc.), which is not limited here. It is understood that when the emergency stop control button of the energy storage power station is triggered, it indicates that at least some areas of the energy storage power station have an emergency fault situation, and corresponding emergency stop measures need to be taken to prevent the emergency fault from escalating, which is not limited here.

[0021] In some embodiments, the emergency stop control button in the energy storage power station has a corresponding emergency stop control range. That is, the emergency stop control button can control the energy storage power station facilities within the emergency stop control range to perform an emergency shutdown. The energy storage power station facilities may include energy storage devices, operation monitoring devices, power conversion devices, etc., which are not limited here. In some embodiments, during the process of controlling the emergency shutdown of the energy storage power station facilities within the emergency stop control range of the triggered emergency stop control button, it may specifically include controlling one or more circuit breakers connected to the triggered emergency stop control button to perform a circuit breaking operation, and / or controlling the part of the power conversion system of the energy storage power station located within the emergency stop control range to perform a shutdown operation, such as disconnecting the AC / DC side switches of the power conversion system in the corresponding area of ​​the emergency stop control range, etc., which are not limited here. In some embodiments, the above-mentioned emergency shutdown control operation is implemented locally by the emergency stop control button through hard-wired connection control or other means. Even if the emergency stop control button experiences an abnormal situation such as a communication failure with the central safety controller, local emergency shutdown control can be executed immediately when the emergency stop control button is triggered, effectively ensuring the safety response capability of the energy storage power station in the event of an abnormal fault.

[0022] In some embodiments, the generated emergency stop control event may specifically include the triggering method of the emergency stop control button (e.g., triggered manually by maintenance personnel, or triggered because some operating states of the energy storage power station meet abnormal emergency stop conditions), the triggering time of the emergency stop control button, the emergency stop control range of the emergency stop control button, and whether all energy storage power station facilities within the emergency stop control range have completed emergency shutdown control, etc. Users can select the content included in the emergency stop control event according to the actual control needs of the energy storage power station, which is not limited here. It is understood that the generated emergency stop control event can reflect the actual situation record of the energy storage power station when the emergency stop control button is triggered, providing a data foundation for the subsequent determination of the emergency stop protection range and the analysis of the causes of energy storage power station faults.

[0023] Step 120: Based on the emergency stop control event and the real-time operation of the energy storage power station, determine the corresponding emergency stop protection range. It is understandable that when an emergency stop control event occurs, the emergency stop control button triggered by maintenance personnel may not completely eliminate or isolate the current fault situation at the energy storage power station. Therefore, it is necessary to further determine the emergency stop protection range that the energy storage power station can currently completely eliminate or isolate the current fault situation based on the emergency stop control event and the real-time operation of the energy storage power station, ensuring the safety of the non-faulty parts of the energy storage power station. The determination of the emergency stop protection range will be explained in detail later and will not be elaborated upon here.

[0024] Step 130: If the emergency stop protection range is larger than the emergency stop control range, control the emergency shutdown of the energy storage power station facilities within the emergency stop protection range. It is understood that if the emergency stop protection range determined based on the emergency stop control event is the same as the emergency stop control range corresponding to the triggered emergency stop control button, it means that triggering the emergency stop control button is sufficient to ensure effective isolation of the abnormal fault, and no additional emergency stop control is required. However, when the emergency stop protection range determined based on the emergency stop control event is larger than the emergency stop control range corresponding to the triggered emergency stop control button, it means that an additional emergency shutdown of the energy storage power station facilities needs to be performed outside the emergency stop control range of the triggered emergency stop control button. How to achieve emergency shutdown of the energy storage power station facilities within the emergency stop protection range will be explained in detail later and will not be elaborated here. It is understandable that through the above process 100, when any emergency stop control button in the energy storage power station is triggered, local shutdown control is immediately executed. Based on the generated emergency stop control event, it is determined whether there are other areas in the energy storage power station that require emergency stop protection. This elevates the isolated emergency stop control button triggering to an analysis of the emergency stop control needs of the entire energy storage power station, accurately identifying the energy storage power station facilities that require emergency stop protection, thereby effectively improving the overall safety of the energy storage power station. The technical solution of this disclosure will be further explained below with reference to specific embodiments.

[0025] In some embodiments of this disclosure, Figure 2 A flowchart illustrating how to determine the corresponding emergency stop protection range based on emergency stop control events and the real-time operation of the energy storage power station is shown, as follows: Figure 2 As shown, process 200 may specifically include the following steps: Step 210: Based on at least two redundant transmission links, synchronize the emergency stop control events to the station-side emergency stop controller of the energy storage power station. In some embodiments, the station-side emergency stop controller can be used to control the emergency shutdown of all energy storage power station facilities. Specifically, in some embodiments, the station-side emergency stop controller can be implemented based on the energy storage power station's Supervisory Control and Data Acquisition (SCADA) system, a programmable logic controller (PLC) with security certification, or an embedded security system. It can acquire the emergency stop control events generated when each emergency stop control button in the energy storage power station is triggered, and summarize, analyze, and store these emergency stop control events. No limitation is made here. In some embodiments, each emergency stop control button in the energy storage power station can be connected to the station-side emergency stop controller via direct or indirect connection to achieve timely synchronization of emergency stop control events. In some embodiments, the communication connection between the emergency stop control button and the station-side emergency stop controller can be based on at least two redundant transmission links. The redundant transmission links can be set according to the deployment environment and / or scale of the energy storage power station, and can be either more flexible wireless transmission links or wired transmission links with higher transmission stability, without limitation. By setting at least two redundant transmission links, the situation where emergency stop control events cannot be synchronized in a timely manner due to communication failure between the emergency stop control button and the station-side emergency stop controller can be greatly avoided.

[0026] Step 220: Based on the matching between the real-time operation status of the energy storage power station and the preset emergency stop control strategy of the station-side emergency stop controller, determine the first protection range corresponding to the emergency stop control event. In some embodiments, the emergency stop protection range may include the first protection range. In some embodiments, the emergency stop control strategy may be preset in the station-side emergency stop controller and derived from summarizing materials such as the historical operation status and safety operation requirements of the energy storage power station, reflecting the emergency stop control needs of the energy storage power station under different fault scenarios. In some embodiments, the real-time operation status of the energy storage power station may include real-time operation parameter information of all energy storage facilities in the energy storage power station and / or real-time environmental information of the energy storage power station. The real-time operating parameters of the energy storage power station facilities reflect the actual operating status of each device in the energy storage power station. By judging whether the real-time operating parameters deviate from the normal operating values, it can be determined whether the abnormal fault of the energy storage power station exceeds the emergency stop control range corresponding to the emergency stop control button. The real-time environmental information can specifically include the wind force level, humidity, and weather conditions of the environment where the energy storage power station is located. When abnormal faults such as fires occur in some energy storage units of the energy storage power station, the overall risk level faced by the energy storage power station can be accurately assessed by combining external environmental information. In some embodiments, specifically, in the process of determining the emergency stop protection range corresponding to the emergency stop control event, the real-time operating parameters of all energy storage power station facilities and / or the real-time environmental information of the energy storage power station can be obtained first. Then, based on the obtained real-time operating parameters and / or real-time environmental information, they can be matched with the emergency stop control strategy preset by the station-end emergency stop controller. Based on the matching results, the risk level of the emergency stop control event can be determined, and then the emergency stop protection range can be determined based on the risk level. For example, if only a single isolated emergency stop control event occurs within an energy storage power station over a period of time, and the real-time operation of all energy storage power station facilities is normal, the preset emergency stop control strategy can determine if the emergency stop control event can eliminate or isolate the energy storage power station's fault. The risk level is low, and there is no need to further expand the emergency stop protection scope beyond the existing emergency stop control range. Alternatively, if multiple emergency stop control events occur simultaneously at an energy storage power station, and the energy storage power station facilities associated with these events exhibit abnormal deviations in their operating data, the preset emergency stop control strategy can determine if a regional fault has occurred at the energy storage power station. The current emergency stop control has not completely eliminated or isolated the energy storage power station fault, resulting in a medium risk level. In this case, the emergency stop protection scope needs to be expanded, and all associated energy storage power stations should be controlled to execute emergency shutdown. Furthermore, if an emergency stop control event occurs at an energy storage power station, and an external fire is discovered in the area where the energy storage power station is located, accompanied by increased wind, the preset emergency stop control strategy can determine if the energy storage power station is currently facing an extremely high safety risk, resulting in a high risk level. In this case, all facilities of the energy storage power station need to be immediately controlled to execute emergency shutdown. No further limitations are specified here.

[0027] In some embodiments of this disclosure, furthermore, when a triggered emergency stop control button has an upper-level emergency stop controller, in addition to synchronizing the emergency stop control event to the station-level emergency stop controller, the application of the emergency stop control can also be synchronized to the upper-level emergency stop controller. This achieves multi-path synchronous redundant reporting of the emergency stop control event, ensuring that the triggering status of any emergency stop control button in the energy storage power station can be promptly detected by the energy storage power station. In some embodiments of this disclosure, Figure 3 This illustrates another flowchart for determining the corresponding emergency stop protection range based on emergency stop control events and the real-time operation of the energy storage power station, as shown below. Figure 3 As shown, process 300 may specifically include the following steps: Step 310: Based on at least two redundant transmission links, synchronize the emergency stop control event to the upper-level emergency stop controller. In some embodiments, the upper-level emergency stop controller is associated with all emergency stop control buttons within a preset geographical area. It is understood that the implementation of step 310 above does not conflict with the implementation of step 320 in the aforementioned embodiments: if the upper-level emergency stop controller of the emergency stop control button is the station-side emergency stop controller, or if the emergency stop control button does not have an upper-level emergency stop controller, then process 200 provided in the aforementioned embodiments can be directly executed to achieve timely synchronous reporting of emergency stop control events; if the emergency stop control button has other upper-level emergency stop controllers that are not station-side emergency stop controllers, then the emergency stop control event can be synchronously synchronized to the upper-level emergency stop controller, and the upper-level emergency stop controller can determine the emergency stop protection range. In some embodiments, for large-scale energy storage power stations, multiple hierarchical emergency stop controllers can be set up hierarchically and distributed between the emergency stop control button and the station-side emergency stop controller to achieve regionalized and refined emergency stop control of the energy storage power station, avoiding the generation of all emergency stop protection ranges being implemented by the station-side emergency stop controller, which is not limited here.

[0028] Step 320: Based on the matching between the real-time operation status of the energy storage power station within a preset geographical area and the preset emergency stop control strategy of the upper-level emergency stop controller, determine the second protection range corresponding to the emergency stop control event. In some embodiments, the emergency stop protection range may include the second protection range. In some embodiments, specifically, when the emergency stop control button is associated with at least one energy storage unit of the energy storage power station, the upper-level emergency stop controller can be used to control the emergency shutdown of all energy storage units within the preset geographical area; correspondingly, in the implementation of step 320 above, when an emergency stop control button is triggered, real-time operating parameter information of all energy storage units within the preset geographical area can be obtained. The above acquisition action can be implemented by the upper-level emergency stop controller, and is not limited here. In some embodiments, further, the real-time operating parameter information of all energy storage units within a preset geographical area can be matched with the preset emergency stop control strategy of the upper-level emergency stop controller. Based on the matching results, the risk level of the emergency stop control event is determined, and then a second protection range is determined based on the risk level. For example, if multiple emergency stop control events occur within a preset geographical area over a period of time, and the real-time operating status of the energy storage units within the preset geographical area fluctuates from normal operating conditions, the preset emergency stop control strategy can be used to determine that there are energy storage power station faults within the preset geographical area that have not been completely eliminated or isolated, resulting in a high risk level. Therefore, the emergency stop protection range needs to be expanded, and all energy storage power stations within the preset geographical area can be controlled to perform emergency shutdowns. This is not limited here. In some embodiments, the upper-level emergency stop controller can be configured to determine the emergency stop protection range only based on the real-time operating parameter information of the energy storage power station facilities within the preset geographical area, thereby reducing the computational load of the upper-level emergency stop controller and the coupling between the upper-level emergency stop controller and the energy storage power station. In other embodiments, the specific implementation of step 320 can also be carried out in the same way as step 220 in the aforementioned embodiments, and is not limited here. In some embodiments, the second protection range generated by the upper-level emergency stop controller can be synchronously reported to the station-level emergency stop controller as an updated emergency stop control event, without limitation. In some embodiments, when there is a difference between the second protection range determined by the upper-level emergency stop controller and the first protection range determined by the station-level emergency stop controller, in order to ensure the overall safety of the energy storage power station, the union of the first protection range and the second protection range can be taken as the emergency stop protection range, without limitation.

[0029] In some embodiments of this disclosure, further, Figure 4 A schematic diagram illustrating a process for controlling the emergency shutdown of energy storage power station facilities within the emergency stop protection range is shown, such as... Figure 4 As shown, process 400 may specifically include the following steps: Step 410: Based on the difference between the emergency stop protection range and the emergency stop control range, identify the energy storage power station facilities that have not been shut down in an emergency within the emergency stop protection range, and identify the emergency stop controllers corresponding to the energy storage power station facilities that have not been shut down in an emergency within the emergency stop protection range.

[0030] Step 420: Issue an emergency stop control command to the emergency stop controller to control the emergency shutdown of energy storage power station facilities that have not yet shut down within the emergency stop protection range. It is understood that, given a corresponding emergency stop controller, the issuance of emergency stop control commands can be based on a hierarchical distributed emergency stop controller topology. The following will further explain and illustrate the emergency stop control method for energy storage power stations provided in this disclosure with reference to specific embodiments.

[0031] In some embodiments, Figure 5 This diagram illustrates a hierarchical distributed configuration of emergency stop control buttons in an energy storage power station. Figure 5 As shown, it may specifically include a local emergency stop control layer 510, a regional emergency stop control layer 520, and a station-side emergency stop control layer 530. In some embodiments, such as Figure 5 As shown, the local emergency stop control layer 510 may include a plurality of first emergency stop control buttons 511 for local emergency stop control of at least some facilities of the energy storage power station; specifically, the first emergency stop control buttons 511 may be physical buttons and are located at key locations of each energy storage unit in the energy storage power station, such as the door of the energy storage container, near the power conversion system, etc., without limitation. In some embodiments, such as Figure 5 As shown, the regional emergency stop control layer 520 may include a plurality of second emergency stop control buttons 521 and the same number of regional emergency stop controllers 522. Each regional emergency stop controller is connected to a corresponding second emergency stop control button 521 and an associated plurality of first emergency stop control buttons 511, and is capable of receiving emergency stop control events provided by the first emergency stop control buttons 511 and determining the corresponding emergency stop protection range, and / or reporting the received emergency stop control events to the station-side emergency stop control layer. In some embodiments, such as Figure 5 As shown, the station-side emergency stop control layer 530 may include a third emergency stop control button 531 and a station-side emergency stop controller 532. The third emergency stop control button 531 is used to control the emergency stop of the entire station. The station-side emergency stop controller 532 is connected to each first emergency stop control button 511, second emergency stop control button 521, and area emergency stop controller 522, respectively. It is used to acquire emergency stop control events for the entire station and issue emergency stop control commands according to the determined emergency stop protection range. This is not limited here. It is understood that, through methods such as... Figure 5The layered distributed topology design shown enables coordinated emergency stop control and rapid response across the entire energy storage power station, significantly improving the overall safety of the station. In some embodiments, users can also set up multiple hierarchical regional emergency stop control layers to achieve more refined regional emergency stop control, while reducing the computational control burden on each regional emergency stop controller; this is not limited here.

[0032] In some embodiments of this disclosure, the emergency stop control method for an energy storage power station, in addition to enabling global emergency stop control of the energy storage power station based on the triggering status of the hierarchically distributed emergency stop control buttons, also supports linkage with other safety control systems of the energy storage power station to further enhance the overall safety of the energy storage power station. In some embodiments, the emergency stop control method for an energy storage power station may further include the following steps: while continuously monitoring the triggering status of each emergency stop control button of the energy storage power station, acquiring the fire alarm generated by the station-wide fire protection system of the energy storage power station; the above acquisition action can be implemented by the station-side emergency stop controller provided in the foregoing embodiments through a communication connection with the station-wide fire protection system, and is not limited here. In some embodiments, further, based on fire alarms, emergency shutdown of energy storage power station facilities within the coverage area of ​​the fire alarm can be controlled, or emergency shutdown of all energy storage power station facilities can be controlled. For example, when the whole-station fire protection system generates a fire alarm in some areas of the energy storage power station, the station-end controller can determine one or more area emergency stop control units according to the area where the fire alarm occurred and send shutdown control commands to these area emergency stop control units, which can realize timely emergency stop control in emergency scenarios. For another example, when the whole-station fire protection system finds that the area in the energy storage power station where the fire alarm occurs is greater than a preset threshold, the station-end controller can consider that the entire energy storage power station is facing a high safety risk at this time, and execute the whole-station shutdown control of the energy storage power station accordingly. Specifically, the shutdown control command can be sent to all area controllers in the form of broadcast, and the shutdown operation can be executed by all area controllers. This is not limited here.

[0033] In some embodiments of this disclosure, Figure 6 A schematic diagram of an emergency stop control system for an energy storage power station is shown, as follows: Figure 6As shown, the system may specifically include an emergency stop control unit 610 and an emergency stop protection unit 620. In some embodiments, the emergency stop control unit 610 may be used to control the emergency stop of the energy storage power station facilities within the emergency stop control range of the triggered emergency stop control button when the emergency stop control button of the energy storage power station is triggered, and generate an emergency stop control event. In some embodiments, the emergency stop protection unit 620 may be used to determine the corresponding emergency stop protection range based on the emergency stop control event and the real-time operating status of the energy storage power station. In some embodiments, the emergency stop control unit 610 may also be used to control the emergency stop of the energy storage power station facilities within the emergency stop protection range when the emergency stop protection range is larger than the emergency stop control range. In some embodiments, the specific functional implementation of the above-mentioned emergency stop control unit 610 and emergency stop protection unit 620 can be implemented with reference to the various steps in the emergency stop control method of the energy storage power station provided in the foregoing embodiments, and will not be elaborated here.

[0034] Some embodiments of this disclosure also relate to an electronic device, such an emergency stop control device, which can be configured as a station-side controller provided in the embodiments of this disclosure, or as a regional controller provided in the embodiments of this disclosure, etc., and is not limited thereto. In some embodiments, Figure 7 A schematic diagram of the structure of an electronic device is shown, such as... Figure 7 As shown, the electronic device includes at least one processor 710 and a memory 720 communicatively connected to the at least one processor. The memory 720 stores instructions that can be executed by the at least one processor 710. The instructions are executed by the at least one processor 710 to enable the at least one processor 710 to perform the various steps in the emergency stop control method of the energy storage power station provided in the foregoing embodiments.
