Description

Technical Field

[0001] The present application relates to the field of power distribution cabin control technology, and in particular to a power distribution cabin control method, system, intelligent terminal and storage medium. Background Art

[0002] In urban power distribution systems, two power supply paths are typically used for redundancy to ensure continuous power supply to critical load nodes. A power supply path is the current transmission path formed by the power supply transmitting electrical energy from the power source to the load node through the distribution cabinet. One of these two power supply paths is designated as the primary power supply path, responsible for powering the load node during daily operation; the other is designated as the auxiliary power supply path, which is in standby mode and provides backup power in the event of an anomaly or failure in the primary power supply path.

[0003] In the prior art, the power supply of the auxiliary power supply path and its corresponding distribution cabinet are usually disconnected and not in operation for a long time. In the event of a failure in the main power supply path, power supply must be switched through the auxiliary power supply path. However, since the distribution cabinet of the auxiliary power supply path is out of service for a long time, its internal components may have problems such as aging and poor contact, and there is a high risk of failure. Based on this situation, there is a high probability that the auxiliary power supply path will not be able to undertake the task of powering the load node in a timely and stable manner, resulting in power interruption of the load node, which in turn affects the continuous operation of the auxiliary node. Summary of the Invention

[0004] In order to provide stable power supply to load nodes and ensure the continuous operation of load nodes, the present application provides a distribution cabin control method, system, intelligent terminal and storage medium.

[0005] In a first aspect, the present application provides a power distribution shelter control method, which adopts the following technical solution:

[0006] A power distribution shelter control method, comprising:

[0007] collecting power supply operation parameters of the first power supply path in real time;

[0008] generating abnormality diagnosis data of the first power supply path when the power supply operation parameter does not meet the preset operation parameter;

[0009] Controlling the first power supply to be disconnected from the first power distribution shelter according to the abnormality diagnosis data;

[0010] Closing the control switch on the communication path to enable the second power supply to supply power to the first power distribution shelter;

[0011] The power supply strategy of the first power distribution shelter is adjusted according to the load demand of the load node.

[0012] By adopting the above technical solution, the power supply operating parameters of the first power supply path are collected in real time, and when the power supply operating parameters do not meet the preset operating parameters, abnormal diagnostic data of the first power supply path is generated. Then, according to the abnormal diagnostic data, the first power supply and the first distribution cabin are controlled to be disconnected and the second power supply is used to supply power to the first distribution cabin, thereby providing stable power supply to the load node to ensure the continuous operation of the load node.

[0013] Optionally, the step of adjusting the power supply strategy of the first power distribution shelter according to the load demand of the load node includes:

[0014] Obtaining a load level of the load node, where the load level includes a first load level, a second load level, and a third load level;

[0015] Determining whether the second power supply meets the load requirements of all the load nodes;

[0016] If not, generating a power supply list according to the load level;

[0017] providing priority and continuous power supply to the load nodes of the first load level according to the power supply list;

[0018] periodically supplying power to the load nodes of the second load level according to the power supply list;

[0019] Delayed power supply is provided to the load nodes of the third load level according to the power supply list.

[0020] By adopting the above technical solution, when the power supply capacity of the second power supply is insufficient to meet the needs of all load nodes, the load nodes can be powered with different strategies based on the load level. The load nodes of the first load level can be given priority for continuous power supply, the load nodes of the second load level can be powered periodically, and the load nodes of the third load level can be powered with delayed power supply. On the one hand, the normal operation of the load nodes of the first load level can be guaranteed, and on the other hand, the energy consumption of the remaining load nodes can be reduced, thereby improving the stability of the overall power supply.

[0021] Optionally, the step of obtaining the load level of the load node includes:

[0022] Obtaining device information of the load node;

[0023] Acquire corresponding device type information, working mode information and working period information according to the device information;

[0024] Performing weighted calculation based on the device type information, the working mode information, and the working period information to obtain a load score;

[0025] The load score is matched with a preset grade score interval to determine the load grade corresponding to the load node.

[0026] By adopting the above technical solution, it is possible to evaluate the degree of dependence of each load node on power supply based on the equipment information of the load node and perform weighted calculation according to factors such as equipment type, working mode and working period, and determine the load level by matching it with the preset grade scoring interval. This can more accurately reflect the degree of dependence of the load node on power supply, and help improve the power supply guarantee capability in the event of power anomalies or resource constraints.

[0027] Optionally, detecting in real time whether the power supply condition of the first power supply meets a preset power supply condition;

[0028] If so, obtaining a power supply restoration order based on the power supply list;

[0029] When the power supply operating parameters meet the preset operating parameters, controlling the control switch on the communication path to open the operation;

[0030] Controlling the first power supply to be connected to the first power distribution shelter in a closed manner;

[0031] The power supply to the load node is restored according to the power supply restoration sequence and in a soft start manner.

[0032] By adopting the above technical solution, when the conditions for restoring power to the first power supply meet the preset requirements, the power supply restoration order can be obtained according to the power supply list, and the load node can be restored to power according to the power supply restoration order and channel soft start method, which can prevent the sudden change of current from causing impact on the power supply system and equipment, reduce the risk of overload, and provide a smooth power supply restoration process to the load node, further improving the power supply stability of the distribution cabin.

[0033] Optionally, before executing the step of controlling the control switch on the communication path to turn on, controlling the first power distribution shelter to access a backup power supply;

[0034] Determining whether the backup power supply meets the power supply requirements of all the load nodes;

[0035] If so, executing a first power supply switching step, the first power supply switching step comprising: controlling the first power distribution shelter to use the backup power supply to supply power to the load node according to the power supply recovery sequence, and controlling the first power distribution shelter to stop using the second power supply to supply power to the load node according to the power supply recovery sequence;

[0036] If not, execute the second power supply switching step, which includes: controlling the first distribution cabin to use the backup power supply to power the load nodes of the first load level, and controlling the first distribution cabin to stop using the second power supply to power the load nodes of the first load level.

[0037] By adopting the above technical solution, the backup power supply can be used to ensure the continuous operation of the load nodes before the first power supply is restored, and different switching strategies can be selected according to the power supply capacity of the backup power supply: if the backup power supply can meet the needs of all load nodes, the backup power supply can be used to achieve seamless power switching of all load nodes; if the backup power supply cannot meet the needs of all load nodes, the reasonable allocation of power resources can be achieved by giving priority to ensuring the power supply of the first load level nodes.

[0038] Optionally, obtaining distribution values ​​of direct current and alternating current of the second power supply;

[0039] Obtaining current power supply type requirement information of all the load nodes;

[0040] Obtaining a power supply allocation value deviation based on the allocation value and the power type requirement information;

[0041] Determining whether the power distribution value deviation is greater than a preset deviation threshold;

[0042] If so, controlling the first power distribution shelter to distribute and adjust the DC power and AC power of the second power supply to obtain a matching power supply;

[0043] The first power distribution shelter is controlled to use the matching power supply to supply power to the load node.

[0044] By adopting the above technical solution, the distribution values ​​of DC and AC of the second power supply are obtained, and combined with the power type demand information of all current load nodes, the power supply distribution value deviation is calculated. When the power supply distribution deviation is greater than the preset deviation threshold, the distribution ratio of DC and AC of the second power supply is adjusted to ensure that different types of load nodes can obtain matching power supply resources, thereby improving the adaptability of the second power supply.

[0045] Optionally, obtaining the load node that cannot be matched with the matching power supply to obtain an unmatched node;

[0046] Acquiring power supply information according to the power type requirement information of the unmatched node;

[0047] Controlling the first power distribution shelter to access a backup power supply;

[0048] Performing a deployment operation on the backup power source according to the power supply information to obtain a backup matching power source that matches the unmatched node;

[0049] Control the first power distribution shelter to use the backup matching power supply to power the unmatched node.

[0050] By adopting the above technical solution, when the second power supply cannot provide power to all load nodes that meets their power type requirements, the unmatched nodes are obtained, and the power supply information is obtained according to their power type requirement information, and the backup power supply is deployed according to the power supply information, so that the backup power supply can be matched with the unmatched nodes, and a backup matched power supply is obtained. Finally, the backup matched power supply is used to power the unmatched nodes to meet the power supply requirements of the unmatched nodes and ensure the normal operation of all load nodes.

[0051] In a second aspect, the present application provides a power distribution shelter control system, which adopts the following technical solutions:

[0052] A power distribution shelter control system, comprising:

[0053] An acquisition module is used to obtain power supply operation parameters;

[0054] A memory, used to store a program of the power distribution shelter control method;

[0055] The program in the memory can be loaded and executed by the processor to implement the power distribution cabin control method.

[0056] By adopting the above technical solution, the power supply operating parameters of the first power supply path are collected in real time, and when the power supply operating parameters do not meet the preset operating parameters, abnormal diagnostic data of the first power supply path is generated. Then, according to the abnormal diagnostic data, the first power supply and the first distribution cabin are controlled to be disconnected and the second power supply is used to supply power to the first distribution cabin, thereby providing stable power supply to the load node to ensure the continuous operation of the load node.

[0057] In a third aspect, the present application provides a smart terminal that adopts the following technical solution:

[0060] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned power distribution shelter control methods.

[0061] In summary, this application includes at least one of the following beneficial technical effects:

[0062] By collecting the power supply operating parameters of the first power supply path in real time and generating abnormal diagnosis data of the first power supply path when the power supply operating parameters do not meet the preset operating parameters, the first power supply and the first power distribution cabin are disconnected according to the abnormal diagnosis data, and the second power supply is used to supply power to the first power distribution cabin, thereby providing stable power supply to the load node to ensure the continuous operation of the load node;

[0063] When the power supply capacity of the second power supply is insufficient to meet the needs of all load nodes, different strategies can be used to power the load nodes based on the load level. For example, the load nodes of the first load level are given priority and continuously powered, the load nodes of the second load level are periodically powered, and the load nodes of the third load level are delayed. On the one hand, the normal operation of the load nodes of the first load level can be guaranteed, and on the other hand, the power consumption of the remaining load nodes can be reduced, thereby improving the stability of the overall power supply.

[0064] When the second power supply cannot provide power to all load nodes that meets their power type requirements, the unmatched nodes are obtained, and the power supply information is obtained according to their power type requirement information. The backup power supply is deployed according to the power supply information so that the backup power supply can be matched with the unmatched nodes and a backup matched power supply is obtained. Finally, the backup matched power supply is used to power the unmatched nodes to meet the power supply requirements of the unmatched nodes and ensure the normal operation of all load nodes.

[0072] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0073] The embodiment of the present application discloses a method for controlling a power distribution shelter. Figure 1 , the distribution shelter control method includes:

[0074] Step S101: collecting power supply operation parameters of the first power supply path in real time.

[0075] The first power supply path refers to a power supply line that is supplied by the first power source and transmits power to each load node through the first distribution cabin, wherein the first power source is the power source that transmits power to the first distribution cabin. The first distribution cabin includes a transformer, an incoming line cabinet, a communication cabinet, a UPS (Uninterruptible Power Supply, uninterruptible power supply system), a feeder cabinet, and other key equipment for power conversion and distribution. Exemplarily, the first power source is the mains power supply of line A. The first power source is connected to the incoming line cabinet. The load node is the terminal power-consuming equipment connected to the feeder cabinet, such as a server, a lighting system, etc.

[0076] The power supply operation parameters refer to the power operation parameters at each node on the first power supply path, including the power supply conditions of the first power supply, the operating status parameters of the first distribution cabin, and the operating status parameters of the load node. Among them, the power supply conditions of the first power supply include: voltage, current, frequency, connectivity status, etc. The operating status parameters of the first distribution cabin include: input / output voltage and current of the transformer; switch status and load current of the incoming cabinet; connection status of the communication cabinet; input / output voltage, battery charge and discharge status, inverter mode, and bypass status of the UPS. The operating status parameters of the load node include: voltage, current, power, etc. of the load node. Various parameters are obtained by various sensors installed in the first distribution cabin.

[0077] The load nodes are also connected to a second power supply path, powered by a second power source, which transmits power to each load node through the second distribution cabin. The structure of the second distribution cabin can refer to that of the first distribution cabin. The second power source and the second distribution cabin are disconnected in normal operation. For example, the second power source can be the B-line mains power or a temporary external power source, such as a generator.

[0078] Step S102: generating abnormality diagnosis data of the first power supply path when the power supply operation parameter does not meet the preset operation parameter.

[0079] The preset operating parameter is a preset constant, which is a parameter range used to determine whether the first power supply path is in a normal operating state and can be adjusted according to actual needs.

[0080] Abnormal diagnostic data refers to the diagnostic result data obtained through system analysis when the power supply operating parameters deviate from the preset operating parameters, including abnormal data on the power supply conditions of the first power supply, abnormal data on the operating status parameters of the first distribution cabin, and abnormal data on the operating status parameters of the load node.

[0081] An abnormality judgment module is configured in the first power distribution cabin. This module is used to collect data on the first power supply path and perform real-time analysis. After an abnormality is triggered, the abnormality judgment module generates abnormality diagnostic data including abnormality type, occurrence location, measured value and time information.

[0082] For example, the mains power supply on line A is in a suspended power supply state, that is, the first power supply cannot provide power to the first distribution cabin. The system detects that the voltage of the first power supply is 0V, so the abnormal diagnostic data shows that the connectivity state in the power supply condition of the first power supply is a circuit breaker state.

[0083] Step S103: according to the abnormality diagnosis data, controlling the first power supply to be disconnected from the first power distribution shelter.

[0084] If the abnormality diagnosis data indicates that the voltage of the first power supply is abnormal, that is, the voltage of the first power supply is less than a preset voltage value, the system determines that the power currently provided by the first power supply cannot guarantee the normal operation of the load node and sends a circuit breaker command to the incoming cabinet, disconnecting the circuit breaker in the incoming cabinet from the first power supply. The preset voltage value is a preset constant and can be adjusted according to actual conditions.

[0085] Step S104: closing the control switch on the communication path to enable the second power supply to supply power to the first power distribution shelter.

[0086] A communication line is pre-installed between the communication cabinet in the first distribution cabin and the communication cabinet in the second distribution cabin, forming a communication path between the first distribution cabin, the communication line and the second distribution cabin, wherein there are communication switches at both ends of the communication line, and the communication switches are normally in the open state.

[0087] In some embodiments, a fault may occur in the second power distribution shelter, preventing the second power source from directly supplying power to the load node through the second power distribution shelter. By closing the control switch on the communication path, that is, closing the connection switches at both ends of the connection line, the current from the second power source is transmitted along the connection line to the first power distribution shelter, thereby supplying power to the first power distribution shelter.

[0088] Step S105: adjusting the power supply strategy of the first power distribution shelter according to the load demand of the load node.

[0089] Load demand refers to the power supply conditions required for the load node to operate normally, including parameters such as voltage, current, frequency, phase, and power type (AC or DC).

[0090] The power supply strategy is a method of distributing and regulating the power supply to the connected power supply through the first distribution cabin, which can be adjusted according to the load demand. The specific steps can be referred to Figure 2 Steps in the embodiment.

[0091] By adopting the above technical solution, the power supply operating parameters of the first power supply path are collected in real time, and when the power supply operating parameters do not meet the preset operating parameters, abnormal diagnostic data of the first power supply path is generated. Then, according to the abnormal diagnostic data, the first power supply and the first distribution cabin are controlled to be disconnected and the second power supply is used to supply power to the first distribution cabin, thereby providing stable power supply to the load node to ensure the continuous operation of the load node.

[0092] Reference Figure 2 The steps of adjusting the power supply strategy of the first power distribution shelter according to the load demand of the load node include:

[0093] Step S201: Obtain the load level of the load node, where the load level includes a first load level, a second load level, and a third load level.

[0094] The load level indicates the degree to which the load node relies on power supply during operation.

[0095] The first load level represents high-priority loads, which means that the equipment needs to ensure stable and continuous power supply during operation; the second load level represents medium-priority loads, which means that the power supply to the equipment can be temporarily interrupted during operation, but power supply needs to be restored first; the third load level represents low-priority loads, which means that in the case of insufficient power supply, power supply to the equipment can be delayed.

[0096] The specific steps for obtaining the load level of the load node can be found in Figure 3 Steps in the embodiment.

[0097] Step S202: Determine whether the second power source meets the load requirements of all load nodes.

[0098] The load demand of all load nodes is the sum of the load demands of all load nodes. If the second power source does not meet the load demands of all load nodes, step S203 is executed.

[0099] For example, there are load nodes 1, 2, and 3. The power of load node 1 during normal operation is 4000 W, the power of load node 2 during normal operation is 2000 W, and the power of load node 3 during normal operation is 1000 W. Therefore, the load power required by all load nodes is 7000 W. However, the output power of the second power supply is 5000 W. Therefore, the second power supply cannot meet the load requirements of all load nodes, so step S203 is executed.

[0100] Step S203: If not, generate a power supply list according to the load level.

[0101] On the other hand, if the second power source satisfies the load requirements of all load nodes, no operation is performed.

[0102] The power supply list is a prioritized power distribution list generated based on the load level of the load nodes. The power supply list lists the power supply priority of each load node and sorts the load nodes in descending order based on the load level.

[0103] Step S204: providing priority and continuous power supply to load nodes of the first load level according to the power supply list.

[0104] After obtaining the power supply list, the load nodes of the first load level in the power supply list are the highest priority power supply objects. The electric energy input by the second power supply is distributed through the first distribution cabin, and the load nodes of the first load level are given priority and continuous power supply.

[0105] For example, in the power supply list, load node 1 is a server, and the server needs to ensure continuous power supply during operation. Therefore, load node 1 can be used as the first load level. Load node 1 is located first in the power supply list, and load node 1 needs to be given priority and continuously powered.

[0106] Step S205: periodically supplying power to the load nodes of the second load level according to the power supply list.

[0107] Periodic power supply is an operation that provides power to a load node for a preset duration, then stops supplying power to the load node and resumes supplying power after a preset interval. Both the preset power supply duration and the preset interval are constants and can be adjusted based on actual needs.

[0108] For example, in the power supply list, load node 2 is an air conditioner, and the air conditioner can temporarily interrupt the power supply during operation. Therefore, load node 2 can be used as the second load level. After the power supply to load node 2 reaches the preset power supply time, the power supply to load node 2 is disconnected through the first distribution cabin, and after the preset interval time, the power supply to load node 2 is restored, and so on. The above steps are repeated to achieve periodic power supply to the load node.

[0109] Step S206: delay power supply to the load nodes of the third load level according to the power supply list.

[0110] Delayed power supply refers to the operation of supplying power to load nodes of a third load level based on remaining power resources while ensuring power supply to load nodes of a first load level.

[0111] For example, in the power supply list, load node 3 is a video wall. When the power supply is insufficient, the video wall can be temporarily shut down and the power supply to the video wall can be restored after sufficient power supply to achieve delayed power supply to the video wall.

[0112] By adopting the above technical solution, when the power supply capacity of the second power supply is insufficient to meet the needs of all load nodes, the load nodes can be powered with different strategies based on the load level. The load nodes of the first load level can be given priority for continuous power supply, the load nodes of the second load level can be powered periodically, and the load nodes of the third load level can be powered with delayed power supply. On the one hand, the normal operation of the load nodes of the first load level can be guaranteed, and on the other hand, the energy consumption of the remaining load nodes can be reduced, thereby improving the stability of the overall power supply.

[0113] Reference Figure 3 ,The steps of obtaining the load level of the load node include:

[0114] Step S301: Obtain device information of the load node.

[0115] Device information refers to the basic attribute information of the electrical equipment at the load node, including device model, rated power, and frequency of use.

[0116] The equipment information can be pre-saved in the database by the operator, and the equipment information corresponding to the load node can be obtained in the database.

[0117] Step S302: Obtain corresponding device type information, working mode information and working period information according to the device information.

[0118] The equipment type information refers to the type of equipment, and the type range can be preset by the operator, such as core control equipment, communication equipment, security equipment, and auxiliary equipment.

[0119] Operating mode information refers to the device's operating status, including continuous operation, intermittent operation, and on-demand operation. On-demand operation means the device doesn't have a fixed operating schedule and only starts when needed. The device's operating status type can be manually entered by the operator based on the device type and stored in the database.

[0120] Operating time information refers to the time periods during which a device is typically used throughout the day, including all-day, peak, and nighttime periods. Operating time information can be obtained from historical device operation records. Peak time periods represent peak electricity usage periods, such as 10:00 AM to 4:00 PM. For example, if device A's operating time in historical records is from 7:00 PM to 4:00 AM the following day, the nighttime period can be used as device A's operating time information.

[0121] Step S303: Perform weighted calculation based on the device type information, working mode information, and working period information to obtain a load score.

[0122] The load score is used to describe the degree of dependence of the equipment corresponding to the load node on power supply. The load level can be determined based on the load score.

[0123] set up:

[0124] T: device type information, α: device type information weight;

[0125] M: working mode information, β: working mode information weight;

[0126] P: working period information, γ: working period information weight;

[0127] Then the load score S=T×α+M×β+P×γ.

[0128] Among them, α+β+γ=1 is satisfied. The device type information weight α, the working mode information weight β, and the working period information weight γ are preset. For example, the device type information weight α can be set to 0.5, the working mode information weight β can be set to 0.3, and the working period information weight γ can be set to 0.2.

[0129] For example, core control equipment can be set to 100 points, communications equipment can be set to 80 points, support equipment can be set to 70 points, and auxiliary equipment can be set to 60 points. Continuous operation can be set to 100 points, intermittent operation can be set to 60 points, and on-demand operation can be set to 40 points. All-day time periods can be set to 100 points, peak time periods can be set to 80 points, and nighttime time periods can be set to 60 points.

[0130] For example, device B is an air conditioner, which is an auxiliary device. Its working mode is intermittent operation and its working time period is all day. Therefore, the load score of device B is S B =60×0.5+60×0.3+100×0.2=68. Device C is a printer, which is an auxiliary device. Its working mode is on-demand operation and its working time period is peak time. Therefore, the load score of device C is S C =60×0.5+40×0.3+80×0.2=58. Device D is a server, which is a core control device. Its working mode is continuous operation and its working time period is all day. Therefore, the load score of device D is S D =100×0.5+100×0.3+100×0.2=100.

[0131] Step S304: Match the load score with a preset grade score interval to determine the load grade corresponding to the load node.

[0132] The preset rating interval is a preset constant interval that can be adjusted according to actual needs. For example, the preset rating interval can be set to 80 to 100 points, 60 to 79 points, and below 60 points to represent the first load level, the second load level, and the third load level, respectively.

[0133] For example, the load score S of device D D =100 points, so device D is at the first load level, that is, the load node corresponding to device D is at the first load level. B It is 68 points, so device B is at the second load level, that is, the load node corresponding to device B is at the second load level.

[0134] By adopting the above technical solution, it is possible to evaluate the degree of dependence of each load node on power supply based on the equipment information of the load node and perform weighted calculation according to factors such as equipment type, working mode and working period, and determine the load level by matching it with the preset grade scoring interval. This can more accurately reflect the degree of dependence of the load node on power supply, and help improve the power supply guarantee capability in the event of power anomalies or resource constraints.

[0135] In the following embodiment, after a certain period of time, the power supply condition of the first power supply can meet the load requirements of all load nodes, so it is necessary to switch to the first power supply for power supply. The embodiment of the present application provides a power supply switching method, referring to Figure 4 , the method comprising:

[0136] Step S401: detecting in real time whether the power supply condition of the first power source meets the preset power supply condition.

[0137] The preset power supply condition is a preset judgment standard, which indicates the basic requirement that the first power source can be restored as the power supply, and can be adjusted according to actual needs.

[0138] For example, the preset power supply conditions may be set as: voltage within the range of 220V ± 11V (i.e., 209V to 231V), frequency maintained between 50Hz ± 0.5Hz, and voltage stability for at least 30 seconds. If the voltage of the first power source is detected to be 225V and the frequency is 50.2Hz, and these conditions are maintained for more than 40 seconds, it is determined that the power supply conditions of the first power source meet the preset power supply conditions, and step S402 may be executed.

[0139] Step S402: If yes, obtain the power supply recovery order based on the power supply list.

[0140] On the other hand, if the power supply condition of the first power source does not meet the preset power supply condition, the process of this embodiment is terminated.

[0141] The power restoration order represents the specific order in which power is restored to each load node through the first distribution shelter after a power source switchover. The power restoration order list has the same ranking for each load node, i.e., it is sorted in descending order based on load level.

[0142] Step S403: When the power supply operation parameters meet the preset operation parameters, the control switches on the communication paths are controlled to be turned on.

[0143] When the power supply operating parameters meet the preset operating parameters, it means that the first power supply can be used as the power supply to power the first distribution cabin, so the control switch on the control communication path is turned on to electrically connect the first power supply to the first distribution cabin.

[0144] Step S404: controlling the first power source to be connected to the first power distribution shelter.

[0145] The first power supply is connected to the circuit breaker in the incoming cabinet of the first power distribution shelter, and the first power supply supplies power to the first power distribution shelter by closing the circuit breaker.

[0146] Step S405: Restore power to the load node in a soft start manner according to the power restoration sequence.

[0147] A soft start strategy gradually increases the voltage or current when power is restored to the load node to control the startup current peak and avoid inrush currents that can damage equipment. This can be achieved using current limiters and inverters installed in the feeder cabinet.

[0148] The system sets startup delay and startup slope parameters for each load node. During power restoration, it delays the startup of each load node one by one according to the power restoration sequence, gradually increasing the power supply to ensure a smooth transition from low power to normal operating power. For example, the system can be configured to restore a load node every 2 seconds and control the startup current of each load node to no more than 1.5 times the rated value, thereby ensuring the stability of the overall power supply system and load safety.

[0149] By adopting the above technical solution, when the conditions for restoring power to the first power supply meet the preset requirements, the power supply restoration order can be obtained according to the power supply list, and the load node can be restored to power according to the power supply restoration order and channel soft start method, which can prevent the sudden change of current from causing impact on the power supply system and equipment, reduce the risk of overload, and provide a smooth power supply restoration process to the load node, further improving the power supply stability of the distribution cabin.

[0150] In the following embodiment, in the process of re-switching the first power supply as the power supply, there is a switching time gap. If the load node is in a running state, it may cause the load node to be powered off. In order to improve this situation, the embodiment of the present application provides a backup power supply access method, referring to Figure 5 , the method comprising:

[0151] Step S501: before executing the step of controlling the switch on the communication path to open, controlling the first power distribution shelter to access the backup power supply.

[0152] The backup power supply is a temporary backup power source. The backup power supply includes a generator set, a battery energy storage system, and a UPS system. The backup power supply is connected to the reserved backup interface of the cabinet of the first distribution cabin.

[0153] In order to prevent the load node from being unable to supply power after the control switch on the communication path is disconnected, causing the load node to shut down, the switch on the reserved backup interface is controlled to be closed so that the first distribution cabin is connected to the backup power supply.

[0154] Step S502: Determine whether the backup power supply meets the power supply requirements of all load nodes.

[0155] The acquisition of power supply requirements of all load nodes may refer to step S202 .

[0156] When the backup power supply meets the power supply requirements of all load nodes, step S503 is executed; when the backup power supply cannot meet the power supply requirements of all load nodes, step S504 is executed.

[0157] Step S503: If yes, execute the first power supply switching step, which includes: controlling the first distribution cabin to use the backup power supply to power the load node according to the power supply recovery sequence, and controlling the first distribution cabin to stop using the second power supply to power the load node according to the power supply recovery sequence.

[0158] If so, it means that the backup power supply meets the power supply requirements of all load nodes, so the first power supply switching step is executed. Among them, there are several feeder cabinets in the first distribution cabin, and each feeder cabinet is connected to the load node. According to the power supply recovery sequence, the feeder cabinet is controlled to access the loop connected to the backup power supply, so that the backup power supply can supply power to the corresponding feeder cabinet and the load node corresponding to the feeder cabinet. At the same time, after the backup power supply successfully supplies power to the feeder cabinet, the loop with the second power supply in the feeder cabinet is disconnected to avoid dual power supply at the same time. According to the power supply recovery sequence, the above steps are repeated to complete the power switching of each feeder cabinet one by one until all load nodes complete the switch from the second power supply to the backup power supply.

[0159] Step S504: If not, execute the second power supply switching step, which includes: controlling the first distribution cabin to use the backup power supply to power the load nodes of the first load level, and controlling the first distribution cabin to stop using the second power supply to power the load nodes of the first load level.

[0160] If not, it means that the backup power supply cannot meet the power supply needs of all load nodes, so the second power supply switching step is performed to ensure stable power supply to the load nodes of the first load level. Among them, the feeder cabinets corresponding to all load nodes of the first load level are obtained to obtain the target feeder cabinet. The target feeder cabinet is connected to the loop connected to the backup power supply, so that the backup power supply supplies power to the load nodes corresponding to the target feeder cabinet. At the same time, after the backup power supply successfully supplies power to the target feeder cabinet, the loop with the second power supply in the target feeder cabinet is disconnected. According to the power supply recovery sequence, the above steps are repeated to complete the power switching of each target feeder cabinet one by one until all load nodes of the first load level complete the switch from the second power supply to the backup power supply.

[0161] By adopting the above technical solution, the backup power supply can be used to ensure the continuous operation of the load nodes before the first power supply is restored, and different switching strategies can be selected according to the power supply capacity of the backup power supply: if the backup power supply can meet the needs of all load nodes, the backup power supply can be used to achieve seamless power switching of all load nodes; if the backup power supply cannot meet the needs of all load nodes, the reasonable allocation of power resources can be achieved by giving priority to ensuring the power supply of the first load level nodes.

[0162] In the following embodiment, when the second power supply is used to supply power to the first power distribution cabin, there may be a situation where some load nodes cannot operate normally due to the difference between the distribution values ​​of AC and DC in the second power supply and the distribution values ​​of AC and DC in the first power supply. In order to improve this problem, the embodiment of the present application provides a power distribution method, referring to Figure 6 , the method comprising:

[0163] Step S601: obtaining the distribution values ​​of the direct current and the alternating current of the second power source.

[0164] The distribution value refers to the power of the direct current and the power of the alternating current in the second power supply.

[0165] In this embodiment, the second power supply is an integrated power supply unit that has the ability to output DC and AC power simultaneously to supply load nodes with different power supply requirements. Two independent multi-function power meters are set in the incoming line cabinet, which can respectively obtain the power P of the DC power in the second power supply. dc and the AC power P ac .

[0166] Step S602: Obtain the power type requirement information of all current load nodes.

[0167] Power supply requirement information indicates the power type (AC or DC) and power required for normal operation of the load node. The operator can enter the device information corresponding to the load node into a database. This information includes parameters such as power type (AC or DC), rated voltage, rated current, and power. Therefore, when obtaining voltage requirement information, the database can be used to retrieve the power type and power required for normal operation of the load node.

[0168] Step S603: obtaining a power distribution value deviation based on the distribution value and the power type requirement information.

[0169] For all load nodes, sum the power of the corresponding power source type, including the total DC power and the total AC power. Subtract the DC power in the allocation value from the total DC power to obtain a DC deviation value, and subtract the AC power in the allocation value from the total AC power to obtain an AC deviation value. The DC deviation value and the AC deviation value are used to obtain the power distribution deviation value.

[0170] For example, there are load nodes 1-10. Load nodes 1 and 1-4 require DC power, with power requirements of 100 W, 200 W, 150 W, and 250 W, respectively. Therefore, the total power of the load nodes with DC power is 700 W. Load nodes 5-10 require AC power, with power requirements of 500 W, 300 W, 600 W, 400 W, 200 W, and 100 W, respectively. Therefore, the total power of the load nodes with AC power is 2100 W. The DC power of the second power supply is 1200 W, and the AC power is 1800 W. Therefore, the DC deviation is +500 W, and the AC deviation is -300 W.

[0171] Step S604: Determine whether the power distribution value deviation is greater than a preset deviation threshold.

[0172] The preset deviation threshold is a preset constant and can be adjusted according to actual needs. In this embodiment, the preset deviation threshold can be set to ±100W.

[0173] By comparing the DC deviation value and the AC deviation value in the power distribution deviation value with the preset deviation thresholds respectively, comparison results A1 and comparison results A2 are obtained. If the power distribution value deviation in comparison result A1 is greater than the preset deviation threshold or the power distribution value deviation in comparison result A2 is greater than the preset deviation threshold, it means that the power distribution value deviation is greater than the preset deviation threshold.

[0174] Step S605: If yes, control the first power distribution shelter to distribute and adjust the DC power and AC power of the second power supply to obtain a matching power supply.

[0175] On the other hand, if the power distribution value deviation is not greater than the preset deviation threshold, no operation is performed.

[0176] If so, the power distribution value deviation is greater than the preset deviation threshold, indicating that the current distribution of DC and AC power provided by the second power supply does not meet the power type requirements of all current load nodes. Therefore, the DC and AC power distribution of the second power supply needs to be adjusted. The incoming line cabinet is equipped with a DC / AC converter and an AC / DC converter, which can convert part of the DC power in the second power supply into DC power or convert part of the AC power into DC power, thereby obtaining a matching power supply.

[0177] For example, the DC power of the second power supply is 1200W, and the AC power is 1800W. The total DC power of all load nodes is 700W, and the total AC power is 2100W. A portion of the DC power is converted into AC power through a DC / AC converter, so that the AC power reaches at least 2100W. Specifically, the excess (1200W-700W)=500W in the DC power is efficiently converted through the DC / AC converter. Considering a conversion efficiency of 90%, it can actually be converted into 500W×0.9=450W of AC power, so that the AC power becomes 2250W, thereby meeting the power supply demand of 2100W of AC power and still retaining a certain power redundancy, thereby obtaining a matching power supply with a DC power of 700W and an AC power of 2250W.

[0178] Step S606: Control the first power distribution shelter to use a matching power supply to supply power to the load node.

[0179] Among them, the first distribution cabin has several feeder cabinets, and each load node is connected to a single feeder cabinet. After obtaining the matching power supply, the matching power supply is allocated according to the power type requirement information of the load node, and the corresponding load node is supplied with power through the feeder cabinet.

[0180] By adopting the above technical solution, the distribution values ​​of DC and AC of the second power supply are obtained, and combined with the power type demand information of all current load nodes, the power supply distribution value deviation is calculated. When the power supply distribution deviation is greater than the preset deviation threshold, the distribution ratio of DC and AC of the second power supply is adjusted to ensure that different types of load nodes can obtain matching power supply resources, thereby improving the adaptability of the second power supply.

[0181] In the following embodiment, after the AC and DC power of the second power supply are distributed and adjusted, there is still a problem that the matching power supply cannot meet the power type requirements of all load nodes. In order to improve this problem, the embodiment of the present application provides a backup power distribution method, referring to Figure 7 , the method comprising:

[0182] Step S701: Obtain a load node that cannot be matched with a matching power supply to obtain an unmatched node.

[0183] After executing step S606, the power of the feeder cabinet corresponding to each load node is obtained. If there is a mismatch with the required power of the load node, the load node is marked to obtain an unmatched node.

[0184] Step S702: obtaining power supply information according to the power type requirement information of the unmatched node.

[0185] Power supply information is represented by the difference between the power of the matching node at the current moment and the required power. For example, after using a matching power supply to supply power to the load nodes, there are load nodes a, b, and c. The power type required by load nodes a, b, and c is AC, and the power requirements are 600W, 500W, and 900W, respectively. The AC power of the matching power supply is 1800W. When the matching power supply is used to distribute power to load nodes a, b, and c, load node a receives 600W, load node b receives 500W, and load node c receives only 700W. Therefore, the power supply information indicates that the power type required by load node c is AC, and the difference between the power at the current moment and the required power is -200W.

[0186] Step S703: Control the first power distribution shelter to access the backup power supply.

[0187] The backup power supply is connected to the incoming cabinet in the first power distribution shelter via a circuit breaker. After executing step S702, the circuit breaker is closed, so that the first power distribution shelter is connected to the backup power supply. The backup power supply can be power provided by a generator.

[0188] Step S704: performing a deployment operation on the backup power source according to the power supply information to obtain a backup matching power source that matches the unmatched node.

[0189] The difference between the current power of the matching node and the required power is used to determine the power required by the backup power source, thereby obtaining the backup power source that matches the unmatched node. If the backup power source is a generator, and the required power type corresponding to the power supply information is DC, an AC / DC converter can be used to convert the generator power into DC.

[0190] For example, the power type required by load node c is AC power, and the difference between the current power and the required power is -200 W. Therefore, the generator needs to provide at least 200 W of power.

[0191] Step S705: Control the first power distribution shelter to use the backup matching power supply to supply power to the unmatched nodes.

[0192] After obtaining a backup power supply that matches the unmatched node, the feeder cabinet is controlled to access the power supply circuit of the backup power supply so that the power of the unmatched node reaches the required power.

[0193] By adopting the above technical solution, when the second power supply cannot provide power to all load nodes that meets their power type requirements, the unmatched nodes are obtained, and the power supply information is obtained according to their power type requirement information, and the backup power supply is deployed according to the power supply information, so that the backup power supply can be matched with the unmatched nodes, and a backup matched power supply is obtained. Finally, the backup matched power supply is used to power the unmatched nodes to meet the power supply requirements of the unmatched nodes and ensure the normal operation of all load nodes.
