[0002] In modern society, electricity supply is one of the key factors in maintaining the normal operation of various infrastructures. With the acceleration of urbanization and the improvement of industrialization, the demand for electricity is constantly increasing, making the stability and reliability of the power supply system particularly important.

[0003] In existing technologies, emergency power supply systems typically rely on pre-set switching mechanisms. By monitoring the overall status of the main power source, it is determined whether to switch to the backup power source. When a main power source failure is detected, the entire line is directly switched to a single type of backup power source, such as a diesel generator set, to supply power to the electrical equipment on the entire line.

[0004] However, this method usually cannot accurately locate the fault, resulting in an inaccurate switching process and may even cause unnecessary power outages. The power supply mode is also relatively simple and has low compatibility, which may not be able to cope with complex fault scenarios. Summary of the Invention

[0046] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0048] A 10kV power distribution system is a common medium-voltage system widely used in industrial, commercial, and urban power distribution. Inevitably, during the process of supplying power to electrical equipment, the power distribution system may experience faults due to various reasons such as line short circuits, equipment damage, external forces, and natural disasters, leading to large-scale power outages. To ensure that critical equipment and facilities can continue to operate when the main power source fails, a corresponding emergency power supply system is generally set up for the power distribution system. This emergency power supply system is required to switch to a suitable backup power source within a very short time to avoid huge losses caused by power outages.

[0049] In one possible example, a diesel generator set is combined with a mains transformer, and an automatic transfer switch (ATS) is used to automatically switch to a backup power source in the event of a fault, so as to ensure power supply to critical loads.

[0050] In another possible example, an energy storage array consisting of electric vehicle power batteries is combined with a diesel generator, and a main / backup power supply mode is achieved through a dual power switching device.

[0051] However, the aforementioned emergency power supply solutions typically employ a combination of manual inspection and monitoring systems to detect power line faults. When the monitoring system detects an anomaly, manual intervention is usually required for troubleshooting and handling, lacking automated control methods and resulting in a slow emergency response speed. Furthermore, they fail to achieve refined circuit monitoring and emergency response, only supporting preset primary / backup switching strategies. These strategies typically use different switching methods for each power source, leading to low compatibility, limited scalability, and a lack of real-time load dynamic optimization capabilities. Therefore, emergency power supply capabilities require further optimization and improvement.

[0052] To address the aforementioned issues, this application provides an emergency power supply control method. This method acquires real-time monitoring data of key nodes in the power supply line accurately and promptly, and quickly locates faulty lines and determines fault information based on this data. Then, according to the fault information, it controls emergency power supply equipment to supply power to the target electrical equipment via a preset interface. At least three different types of emergency power supplies are provided, making the emergency response more flexible and rapid. This allows for more efficient and precise control of emergency power supply equipment for power switching, thereby reducing the impact of line faults. Furthermore, the preset interface in this application uses a unified universal power interface protocol, enhancing the compatibility and scalability of the emergency power supply. More emergency power supply equipment can be added based on actual power demand, better meeting practical needs.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0054] It should be noted that the executing entity of the emergency power supply control method provided in this application embodiment can be an emergency power supply control device, which can be deployed in an emergency power supply system. This emergency power supply system can be mounted on electronic devices such as computers and servers; this application embodiment does not impose any limitations. This application embodiment uses an emergency power supply control device as an example for detailed explanation.

[0055] Figure 1 This is a flowchart illustrating an emergency power supply control method provided in an embodiment of this application. Figure 1 As shown, the emergency power supply control method provided in this application embodiment may include:

[0056] S101. Obtain real-time monitoring data of each preset key node in the power supply line of the main power supply; wherein, the power supply line includes multiple segmented lines; the real-time monitoring data is used to indicate the actual power supply status of the segmented lines associated with the preset key nodes.

[0057] For example, the main power source can be the mains power supplied by a power plant, etc., and this application embodiment is not limited to this. In a power supply system, the main power supply line is usually composed of multiple segmented lines, and different electrical devices can be connected to each segmented line. In order to effectively monitor the power supply status of the power supply line, monitoring equipment, such as current sensors, voltage sensors, temperature sensors, and other necessary data acquisition devices, can be installed at preset key nodes of the power supply line to collect monitoring data in real time and transmit it to the emergency power supply control device of this application embodiment through fiber optic communication networks, etc.

[0058] The preset key nodes are nodes that play an important role in the power supply line, such as substations, branch points, or other important power transmission nodes. Real-time monitoring data may include electrical parameters such as voltage, current, power factor, and frequency; this application embodiment is not limited to these parameters, as they can all be collected by monitoring equipment. By using real-time monitoring data on the segmented lines associated with the preset key nodes, the actual power supply status of that segmented line can be determined more accurately, thereby helping to identify faulty lines and their fault information.

[0059] S102. Based on real-time monitoring data, determine the fault information of the faulty line; the faulty line is a segment of the power supply line with abnormal power supply.

[0060] For example, once real-time monitoring data is collected, analyzing this data can identify anomalies in the power supply lines. Faulty lines refer to those sections of the line experiencing abnormal power supply, which may manifest as low voltage, high current, abnormal frequency, etc., leading to power supply abnormalities. By analyzing the real-time monitoring data, detailed fault information such as the time of the fault, the specific location of the faulty line, the fault type (e.g., short circuit, open circuit, busbar undervoltage), the fault duration, and possible causes can be determined.

[0061] Optionally, in one possible embodiment, determining the fault information of the faulty line based on real-time monitoring data may include:

[0062] S1. Perform anomaly analysis on the real-time monitoring data to identify abnormal data in the real-time monitoring data;

[0063] S2. Based on the node identification information of the abnormal data, determine the preset key node corresponding to the abnormal data, and determine the segmented line associated with the preset key node corresponding to the abnormal data as the faulty line.

[0064] S3. Perform data analysis and processing on abnormal data to determine the fault information of the faulty line.

[0065] For example, anomaly detection algorithms such as threshold detection, statistical analysis, and machine learning models can be used to analyze real-time monitoring data to identify abnormal data that deviates from the normal range. These abnormal data may include low voltage, high current, frequency fluctuations, etc. Once abnormal data is detected, it can be marked to indicate the presence of a fault.

[0066] Understandably, each piece of abnormal data has its corresponding node identifier, which is used to determine from which critical node the abnormal data was collected. Therefore, based on the node identifier of the abnormal data, the preset critical node corresponding to the abnormal data can be identified, thereby determining the faulty line.

[0067] Furthermore, in-depth data analysis of abnormal data can determine the nature and cause of the fault, thereby identifying detailed fault information. For example, by analyzing the temporal trends of abnormal data, the occurrence time, duration, and presence of periodic or sudden characteristics of the fault can be identified. Pattern recognition techniques (such as machine learning algorithms) can be used to identify specific patterns in abnormal data, which may be associated with known fault types. Statistical methods (such as mean, standard deviation, and correlation analysis) can be applied to quantify the characteristics of abnormal data and compare them with data under normal operating conditions. Then, based on the analysis results, the specific type of fault can be determined. For example, a voltage drop may indicate a short circuit, a current overload may indicate overload operation, and frequency anomalies may indicate synchronization problems. Using a predefined fault type library or model to match the analysis results can identify the most likely fault type. Based on the fault type, the fault duration can also be estimated, and possible causes of the fault can be analyzed.

[0068] By analyzing real-time monitoring data, abnormal data can be identified first, followed by fault information. This effectively identifies and diagnoses faults in power supply lines, improving the accuracy and timeliness of fault detection and facilitating faster and more accurate emergency power supply.

[0069] Optionally, in one possible embodiment, step S3, performing data analysis on the abnormal data to determine the fault information of the faulty line, may include:

[0070] S31. Determine the feature similarity between abnormal data and historical fault data; feature similarity is used to indicate the degree of similarity between the data characteristics of abnormal data and the data characteristics of historical fault data.

[0071] S32. If the feature similarity is greater than or equal to the preset threshold, then the fault information corresponding to the historical fault data is determined as the fault information of the faulty line.

[0072] For example, key features can be extracted from abnormal data. These features may include the values ​​and trends of parameters such as voltage, current, frequency, and power factor. Similarly, corresponding features can be extracted from historical fault data. Then, similarity measurement methods such as Euclidean distance, cosine similarity, and dynamic time warping are used to calculate the feature similarity between the abnormal data and the historical fault data. This feature similarity can be a numerical value representing the degree of similarity between the features of the abnormal data and the features of the historical fault data. A high feature similarity indicates that the features of the abnormal data are very similar to the features of a certain historical fault data, which may mean that the current fault and the historical fault have the same or similar causes and manifestations.

[0073] A preset threshold is a standard used to determine whether the similarity is high enough. This threshold can be set based on historical data analysis, expert experience, or experimental results. The setting of the threshold needs to balance the risks of false alarms and false negatives. The feature similarity between the abnormal data and historical fault data is compared with the preset threshold. If the feature similarity is greater than or equal to the preset threshold, the current abnormal data is considered to be very similar to a certain historical fault data. Therefore, the fault information corresponding to that historical fault data can be directly used as the fault information of the current faulty line.

[0074] This application embodiment can quickly and accurately determine fault information by calculating the feature similarity between abnormal data and historical fault data. Utilizing the experience of historical data can also improve the efficiency and accuracy of fault diagnosis, which helps to reduce fault handling time and improve the reliability of fault diagnosis.

[0075] S103. Based on the fault information of the faulty line, control the emergency power supply equipment to supply power to the target electrical equipment through a preset interface; the emergency power supply equipment includes at least one of the following: main power supply using a backup line, energy storage equipment, and power generation equipment.

[0076] For example, after identifying the faulty line, the system can quickly switch to emergency power supply mode based on the fault information to ensure continuous power supply to the target electrical equipment. The preset interface uses a unified and standardized universal power interface protocol. This interface can be a physical connection (such as a specific power plug, power interface, etc.) and / or a communication protocol (such as Modbus, CAN bus, etc.), designed to ensure seamless integration between different types of emergency power supply equipment and the target electrical equipment, achieving compatibility, operability, and scalability between different devices. In this embodiment, the emergency power supply equipment may include a main power supply using a backup line, energy storage devices, and generators.

[0077] Among them, the backup line refers to the redundant line of the main power supply line, which is used to start when the main power supply line fails and supports automatic ring network switching (switching time <100ms). Energy storage equipment refers to portable devices that store electrical energy and can supply power externally. It can adopt a hybrid technology of lithium batteries and supercapacitors, balancing fast response (switching time <10ms) and long endurance (>4 hours). It can be a standalone device such as a battery or super buffer capacitor, or it can be an energy storage device mounted on other equipment, such as the battery in an electric vehicle. Power generation equipment refers to equipment with power generation function, such as diesel generators, gas generators, and generator vehicles, which support seamless grid connection (synchronization time <15s).

[0078] After obtaining fault information about the faulty line, and based on this information, the system can automatically control emergency power supply equipment via a preset interface to quickly provide power to the target electrical equipment, reducing the time and impact of power outages. The target electrical equipment may include all electrical equipment on the faulty line, or it may only include equipment requiring emergency power; this embodiment does not impose any limitations. When the target electrical equipment only includes equipment requiring emergency power, the emergency power supply equipment and the target power supply equipment can be identified first, and then the emergency power supply equipment can be controlled to supply power to the target equipment.

[0079] Optionally, in one possible embodiment, controlling emergency power supply equipment to supply power to the target electrical equipment through a preset interface based on the fault information of the faulty line may include:

[0080] S10. Based on the fault information of the faulty line, determine the emergency power supply equipment;

[0081] S20. Determine the target electrical equipment based on the power grid topology information and the first preset priority information of the faulty line; the power grid topology information is used to indicate the distribution of electrical equipment on the faulty line, and the first preset priority information is used to indicate the power consumption sequence of each electrical equipment during the power outage.

[0082] S30. Control the emergency power supply equipment to supply power to the target electrical equipment through the preset interface.

[0083] For example, appropriate emergency power supply equipment can be selected based on the fault type indicated by the fault information of the faulty line and the capacity, response speed, availability and operating cost of the available emergency equipment.

[0084] Optionally, in one possible embodiment, step S10, determining the emergency power supply equipment based on the fault information of the faulty line, may include:

[0085] S11. If the fault information indicates that the faulty line is a busbar undervoltage, then the main power supply of the backup line is determined to be the emergency power supply equipment.

[0086] S12. If the fault information indicates that the faulty line is a short circuit, then the energy storage device is determined to be an emergency power supply device.

[0087] S13. If the fault information indicates that the faulty line is open, then the power generation equipment is determined to be an emergency power supply equipment.

[0088] For example, bus voltage loss typically refers to a drop in voltage on the bus to an unacceptable level, possibly due to an upstream power supply failure or a problem with the bus itself. This failure affects all downstream equipment connected to that bus. In the event of a bus voltage loss, the most immediate emergency measure is to switch to a backup line. These backup lines are usually pre-configured and exist in parallel with the main power supply. The main power supply to the backup line can be quickly connected to restore the bus to its normal voltage level, thereby restoring power to the downstream equipment.

[0089] A line short circuit occurs when current flows through an unexpected path in a line, typically causing a current surge and a voltage drop. Short circuit faults require rapid isolation to prevent equipment damage and the spread of the fault. Energy storage devices can respond quickly and provide stable power output. Therefore, when a short circuit is identified, energy storage devices can be selected as emergency power supplies. This allows them to immediately provide power to critical loads after the short circuit is isolated, ensuring the continued operation of important equipment.

[0090] A circuit break refers to an interruption in the current path, preventing power from being transmitted to downstream equipment. This type of fault can be caused by physical disconnection, equipment malfunction, or human error, and usually results in a prolonged power outage. Power generation equipment, such as diesel or gas generators, can operate independently of the power grid, providing continuous power output. Therefore, in the event of a circuit break, power generation equipment can be selected as an emergency power supply to provide power to affected equipment until the fault is repaired.

[0091] This application selects the most suitable emergency power supply equipment based on the specific type of fault. This targeted emergency response strategy improves the flexibility and reliability of the system, ensuring effective power support under various fault conditions.

[0092] Furthermore, based on the power grid topology information of the faulty line and the first preset priority information, the target electrical equipment can also be identified. The power grid topology information provides detailed information about the power supply network structure and the distribution of electrical equipment. By analyzing the power grid topology information, it can be determined which electrical equipment is located on the faulty line and affected. The first preset priority information defines the power supply order for each electrical device during a power outage, typically based on factors such as the importance of the equipment and its impact on business operations. Based on the first preset priority information, it can also be determined which electrical devices should receive priority power supply under emergency power conditions. For example, generally, hospitals have priority > residents > industries. In certain special scenarios, such as data centers, important exams, important competitions, and important meetings, higher priorities may be given. Combining the power grid topology information and the first preset priority information, the target electrical equipment requiring emergency power supply can be identified. Specifically, these devices are usually those critical to business continuity, such as critical servers, medical equipment, and communication equipment.

[0093] Once the emergency power supply equipment and the target electrical equipment are identified, the emergency power supply equipment can be controlled to supply power to the target electrical equipment through a preset interface to ensure the normal power supply of the target electrical equipment.

[0094] Optionally, in one possible embodiment, step S30, controlling the emergency power supply equipment to supply power to the target electrical equipment through a preset interface, may include:

[0095] The emergency power supply equipment is connected to the target electrical equipment through a preset interface, and the emergency power supply equipment is controlled to discharge to the target electrical equipment.

[0096] For example, a control signal can be sent to the emergency power supply equipment through a preset interface to instruct it to start supplying power to the target electrical equipment. The control signal may include parameters such as connection command, discharge start command, and set discharge current and voltage to control the connection between the emergency power supply equipment and the target electrical equipment and ensure that the power supply process meets the needs of the target electrical equipment.

[0097] This control mechanism based on a preset interface improves system compatibility and operational efficiency, reduces the need for human intervention, and enhances the reliability and emergency response capabilities of the power system. It enables rapid response in the event of a fault, ensuring continuous power supply to critical equipment. Furthermore, due to the versatility of the preset interface, various emergency power supply devices can be added promptly to meet power loads when power supply is insufficient.

[0098] The emergency power supply control method provided in this application significantly improves the accuracy and timeliness of fault detection by real-time monitoring of key nodes in the power supply line, ensuring rapid fault identification and location. By intelligently selecting emergency power supply equipment and target electrical equipment, it optimizes resource allocation and utilization efficiency, providing stable power assurance for critical electrical equipment. Preset interfaces also enhance the flexibility of emergency power supply, enabling compatibility, operability, and scalability between different devices. The emergency power supply control method provided in this application, from various aspects, achieves multi-source collaborative emergency power supply, improving the response accuracy, reliability, and scalability of emergency power supply, and reducing the impact of power supply failures.

[0099] For example, after emergency power supply is initiated for the target electrical equipment, the status of the emergency power supply equipment and the target electrical equipment can be continuously monitored, and discharge parameters can be adjusted as needed to optimize the power supply effect. Optionally, based on the above embodiments, in one possible embodiment, the emergency power supply control method provided in this application embodiment may further include:

[0100] S100: Real-time acquisition of the remaining power of emergency power supply equipment and the actual power consumption of target electrical equipment;

[0101] S200. Based on the remaining power, actual power consumption, and second preset priority information, the target electrical equipment is re-determined; the second preset priority information is used to indicate the power consumption sequence of each electrical equipment when the power supply capacity of the emergency power supply equipment is insufficient.

[0102] For example, after emergency power supply is initiated for the target electrical equipment, the remaining power of the emergency power supply equipment can be continuously monitored, such as the battery level of energy storage devices, the available capacity of backup lines, and the fuel reserves of power generation equipment, to accurately understand the current status and sustainable power supply capacity of the emergency power supply equipment. Simultaneously, the actual power consumption of the target electrical equipment is monitored; by acquiring actual power consumption data, the current power demand can be assessed. Then, based on the real-time acquired remaining power and actual power consumption, it can be assessed whether the current emergency power supply equipment can meet the continuous power demand of all target electrical equipment. If the power supply capacity is insufficient, the list of target electrical equipment can be dynamically adjusted according to the second preset priority information, prioritizing power supply to high-priority equipment and temporarily interrupting or reducing power supply to low-priority equipment.

[0103] This dynamic adjustment optimizes emergency power supply strategies, ensuring that limited power resources are allocated to the most critical electrical equipment. This helps maximize the effectiveness of emergency power supply equipment, extend the uptime of critical equipment, and reduce negative impacts on business operations.

[0104] For example, Figure 2This is a schematic diagram of the architecture of an emergency power supply system provided in an embodiment of this application. Figure 2 As shown, based on the emergency power supply control method provided in this application embodiment, the power parameters at each preset key node 210 can be monitored in real time. Then, based on the real-time monitored data, the faulty line and fault information can be determined. Thus, the main power supply of the backup line 230, or an energy storage device, or a generator can be controlled via the preset interface 220 to supply power to the target electrical equipment. For example, if a short circuit occurs in a segment of the line associated with the preset key node 210, the energy storage device can be controlled via the preset interface 220 to provide emergency power to the electrical equipment 21~2n.

[0105] For example, Figure 3 This is a flowchart illustrating another emergency power supply control method provided in an embodiment of this application. Figure 3 As shown, the emergency power supply control method provided in this application embodiment may include:

[0106] S301. Obtain real-time monitoring data of each preset key node in the power supply line of the main power supply.

[0107] The power supply line includes multiple segmented lines; real-time monitoring data is used to indicate the actual power supply status of the segmented lines associated with preset key nodes.

[0108] S302. Determine the fault information of the faulty line based on real-time monitoring data.

[0109] Among them, the faulty line is the section of the power supply line where the power supply is abnormal.

[0110] S303. Based on the power grid topology information of the faulty line and the first preset priority information, determine the target electrical equipment.

[0111] Among them, the power grid topology information is used to indicate the distribution of electrical equipment on the faulty line, and the first preset priority information is used to indicate the power consumption sequence of each electrical device during the power outage.

[0112] S304. Based on the fault information of the faulty line, activate the emergency power supply equipment.

[0113] S3041. If the fault information indicates that the faulty line is a busbar undervoltage, then initiate a Level 1 response and activate the backup line of the main power supply through a preset interface.
