[0007] The actual load of each of the optional power supply devices is calculated based on the power request data received by the target power supply system and the power transmission path.

[0008] The power capacity of the target power supply system is determined based on all the actual loads.

[0009] In an alternative approach, the method further includes:

[0010] Determine the connection relationships between the optional power supply devices and the direction of power transmission;

[0011] The power transmission path is determined based on the connection relationship and the direction of power transmission.

[0012] In an alternative approach, the method further includes:

[0013] The power supply request time series sent to the target power supply system is filtered according to the request processing progress to obtain the power supply request data.

[0014] In an alternative approach, the method further includes:

[0015] Based on the power transmission path, a transmission initiation device, a transmission termination device, and an upstream power supply device corresponding to each of the multiple optional power supply devices are determined from among the multiple optional power supply devices; wherein, the transmission initiation device is the optional power supply device directly connected to the power request sender; the transmission termination device is the optional power supply device directly connected to the mains power; and the upstream power supply device is another optional power supply device that sends the power request data to the current optional power supply device;

[0016] Starting from the transmission initiation device and ending at the transmission termination device, the actual load of each optional power supply device is determined sequentially based on the actual load of the upstream power supply device corresponding to each optional power supply device.

[0017] In an alternative approach, the method further includes:

[0018] The actual load of the optional power supply device is determined based on the sum of the actual loads of all the upstream power supply devices corresponding to the optional power supply device.

[0019] In an alternative approach, the method further includes:

[0020] Determine the device type of the optional power supply equipment;

[0021] The actual load of each of the optional power supply devices is determined according to the sum of the device type and the actual load.

[0022] In an alternative approach, the method further includes:

[0023] Determine the load performance indicators and design parameters corresponding to the optional power supply equipment based on the equipment type;

[0024] Based on the load performance index, feature extraction is performed on the sum of the actual loads to obtain the actual index values;

[0025] The actual load is obtained by calculating based on the actual index value and the design parameters.

[0026] According to another aspect of the present invention, a power supply system capacity calculation device is provided, comprising:

[0027] The first determining module is used to determine the power transmission path between multiple optional power supply devices in the target power supply system;

[0028] The calculation module is used to calculate the actual load of each of the optional power supply devices based on the power supply request data received by the target power supply system and the power transmission path.

[0029] The second determining module is used to determine the power capacity of the target power supply system based on all the actual loads.

[0030] According to another aspect of the present invention, a power supply system capacity calculation device is provided, comprising:

[0031] The processor, memory, communication interface, and communication bus are provided, wherein the processor, memory, and communication interface communicate with each other via the communication bus.

[0033] According to another aspect of the present invention, a computer-readable storage medium is provided, the storage medium storing at least one executable instruction that causes a power supply system capacity calculation device to perform the operation of the power supply system capacity calculation method as described in any of the preceding claims.

[0034] This invention addresses the issue of determining power transmission paths between multiple selectable power supply devices in a target power supply system. Each power supply device processes mains power so that it can be processed by the next level of power supply device. After processing through multiple levels of power supply devices, the power can be output to communication equipment rooms, etc. The power transmission path reflects the hierarchical relationship of the power load between the power supply devices. Based on the power request data received by the target power supply system and the power transmission path, the actual load of each selectable power supply device is calculated. The power capacity of the target power supply system is determined based on all the actual loads, thus differentiating it from the prior art where the power supply system capacity calculation is performed in a single step. Generally, calculations can only be performed on specific indicators of some core equipment. However, the power supply system is a whole, and the safety of some equipment does not represent the power supply safety of the entire system. This leads to poor accuracy in calculating the power supply system capacity. The present invention addresses this by considering the target power supply system as a whole and transmitting power request data step by step among all available power supply equipment in the system according to the power transmission path. The data is then distributed or aggregated among upstream and downstream equipment at each level, thereby obtaining the capacity of each available power supply equipment. Finally, the capacity of the entire system can be calculated from the entire process, improving the accuracy of power supply system capacity calculation and effectively ensuring the power supply safety of the communication equipment room.

[0035] The above description is merely an overview of the technical solutions of the embodiments of the present invention. In order to better understand the technical means of the embodiments of the present invention and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0041] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0042] Before describing the embodiments of the present invention, the prior art and its problems will be explained:

[0043] With the rapid development of communication technology and the increasing power consumption of equipment, the bottleneck of power capacity has become increasingly prominent. The huge losses caused by power outages in communication equipment rooms are frequently reported in the news. Therefore, telecommunications operators have increasingly higher requirements for the management of communication equipment rooms, making it particularly important to achieve system-level capacity calculation and capacity early warning within these rooms.

[0044] Existing power system capacity calculation methods mainly include: in the field of power communication, calculating the capacity index of the battery pack by obtaining the number of rectifier modules and battery packs of the communication power supply; in the field of communication equipment rooms, calculating the capacity index of a single device by obtaining the attribute information of the independent equipment in the equipment room; each independent device only calculates its current capacity index to reflect the current load level of the device.

[0045] The problem lies in that the existing methods only calculate the capacity indicators of some devices in the communication machine room, and do not cover all devices in the machine room. However, the power supply system of the communication machine room is a whole, and the power supply safety of some devices in the system cannot reflect the system-level capacity early warning situation. Secondly, the capacity calculation of each existing power supply device is independent, only calculating the current capacity indicator, which cannot measure the load degree of the current device from multiple dimensions (such as the time dimension and the physical link dimension), so the calculated indicator is not accurate enough. Furthermore, the existing methods do not form a general calculation method for multiple types of power supply devices, which is not conducive to refined management.

[0046] Therefore, the existing capacity calculation of the power supply system in the communication machine room has the problems of low accuracy and insufficient intelligence, which leads to the failure to guarantee the power supply safety of the machine room.

[0047] Relevant terms are explained as follows:

[0048] Power distribution: a link in the power system that is directly connected to users and distributes electric energy to users. The power distribution system consists of distribution substations, high-voltage distribution lines, distribution transformers, low-voltage distribution lines and corresponding control and protection devices.

[0049] UPS: Uninterruptible Power Supply, which is an uninterruptible power supply containing an energy storage device. It is mainly used to provide uninterrupted power for some devices that have high requirements for power supply stability. When the mains input is normal, the UPS stabilizes the mains and supplies it to the load for use. At this time, the UPS is an AC voltage stabilizer, and at the same time, it charges the built-in battery; when the mains power is interrupted (accidental power failure), the UPS immediately converts the DC electric energy of the battery through an inverter to continuously supply 220V AC power to the load, so that the load maintains normal operation and protects the software and hardware of the load from damage. UPS equipment usually provides protection against excessively high or excessively low voltage.

[0050] Small busbar: a common line for control power supply, signal power supply, protection power supply, AC voltage, AC power supply, etc.

[0051] High and low voltage power distribution cabinet: a power distribution device used for electric energy distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switch cabinets, then step down the voltage through transformers, and then lead out from the low-voltage side of the transformers to the low-voltage power distribution cabinets.

[0052] High-voltage power distribution cabinet: a switchgear used in the high-voltage part of the power supply system, which is a power distribution device for electric energy distribution, control, metering and cable connection. Generally, power stations and substations use high-voltage switch cabinets, then step down the voltage through transformers, and then connect to the low-voltage switch cabinets.

[0053] High-voltage incoming line cabinet: A high-voltage cabinet that disconnects the high-voltage incoming power supply. It is not actually a true incoming line cabinet. Generally, the incoming line is connected to the isolation cabinet, but it has a circuit breaker (vacuum) that can disconnect the incoming power supply, so it is called an incoming line cabinet.

[0054] High-voltage outgoing switchgear: Used for distributing and transmitting electrical energy, it is generally connected to transformers or high-voltage electrical equipment (motors) and high-voltage compensation equipment and other specialized equipment.

[0055] Low-voltage outgoing switchgear: Used for distributing and transmitting electrical energy. Unlike high-voltage outgoing switchgear, it is directly connected to the distribution box through busbar trunking and cables to supply power to the equipment that needs to use it. The switch is usually a molded case circuit breaker.

[0056] Figure 1 A flowchart of a power supply system capacity calculation method provided in an embodiment of the present invention is shown. This method is executed by a computer processing device. The computer processing device may include a mobile phone, a laptop computer, etc.

[0057] like Figure 1 As shown, the method includes the following steps:

[0058] Step 10: Determine the power transmission path between multiple optional power supply devices in the target power supply system.

[0059] In one embodiment of the present invention, the target power supply system may be one or more power supply physical links corresponding to communication equipment rooms. One end of the power supply physical link is connected to the mains power to receive the input of the mains power, and the other end is connected to the module to be powered in the communication equipment room to output the processed power to the module to be powered. Considering that the power supply equipment may be located in multiple equipment rooms, such as a target power supply system that can output to multiple communication equipment rooms (which can be achieved by setting up multiple column cabinets), the target power supply system may also correspond to multiple communication equipment rooms.

[0060] Optional power supply equipment is a device that processes and transmits electrical energy. Optional power supply equipment can receive mains power or electrical energy processed by other optional power supply equipment, and output electrical energy. It can output to other optional power supply equipment for secondary processing, or directly output to the device to be powered.

[0061] Specifically, the optional power supply equipment may include at least one of the following processing equipment commonly used in communication equipment rooms for power supply: DC power supply cabinet, AC power supply cabinet, AC busbar, DC distribution cabinet, DC system, AC extension cabinet, UPS system, AC distribution panel, UPS input distribution cabinet, primary low-voltage outgoing cabinet, secondary low-voltage outgoing cabinet, secondary low-voltage incoming cabinet, primary low-voltage incoming cabinet, primary low-voltage generator, transformer, secondary high-voltage outgoing cabinet, secondary high-voltage incoming cabinet, primary high-voltage outgoing cabinet, high-voltage generator, primary high-voltage incoming cabinet, etc.

[0062] In one embodiment of the present invention, the power transmission path is used to characterize the relationship between power input and output among multiple optional power supply devices. For example, the mains power is input to the primary high-voltage incoming cabinet, the primary high-voltage incoming cabinet outputs power to the primary high-voltage outgoing cabinet and the high-voltage generator respectively, and then the primary high-voltage incoming cabinet outputs power to the primary high-voltage outgoing cabinet and the high-voltage generator outputs power to the secondary high-voltage outgoing cabinet.

[0063] It is easy to understand that the transmission of electrical energy is from the mains power to the power supply equipment of the distant user, then to the power supply equipment of the nearby user, and finally to the user who sent the power supply request. On the other hand, the electrical load is sent by the user to the power supply equipment of the nearby user, then to the power supply equipment of the distant user, and finally to the mains power. Therefore, the connection relationship of each power supply equipment in the transmission path of electrical energy and the transmission path of electrical load are the same, but the connection direction is opposite.

[0064] In one embodiment of the present invention, the connections and directions of power transmission (i.e., input and output relationships) between all optional power supply devices in the target power supply system are first analyzed to obtain the power transmission path. Therefore, step 10 further includes:

[0065] Step 101: Determine the connection relationship between the optional power supply devices and the direction of power transmission.

[0066] In one embodiment of the present invention, the connection relationship can be a direct connection between two devices. The direction of power transmission is used to characterize the input and output of power between two directly connected optional power supply devices. For example, in the above example, the primary high-voltage incoming cabinet outputs power to the primary high-voltage outgoing cabinet and the high-voltage generator respectively. Then the direction of power transmission is from the primary high-voltage incoming cabinet to the primary high-voltage outgoing cabinet.

[0067] Step 102: Determine the power transmission path based on the connection relationship and the power transmission direction.

[0068] In one embodiment of the present invention, multiple optional power supply devices are connected according to their connection relationships, and then the connections between the optional power supply devices are directionally marked based on the power transmission direction, thereby obtaining a multi-level power transmission path between the user to be powered and the mains power. In another embodiment of the present invention, the obtained power transmission path can be as follows: Figure 2 As shown, where, Figure 2 The arrows in the diagram indicate the direction in which power request data is sent, i.e., the opposite direction of power transmission.

[0069] Step 20: Calculate the actual load of each of the optional power supply devices based on the power supply request data received by the target power supply system and the power transmission path.

[0070] In one embodiment of the present invention, power supply request data is sent by the power-receiving party (such as various modules in a communication room) to the target power supply system. Specifically, it may be sent to the final output node of the power transmission path, such as at least one column head cabinet.

[0071] The power transmission path can be viewed as a water flow system for power transmission. The optional power supply equipment that receives power (i.e. sends power to the load) can be viewed as the upstream of the water flow system, while the optional power supply equipment that receives the load (i.e. sends power) can be viewed as the downstream of the water flow system.

[0072] It's easy to understand that water flows downstream, and at each node, the flow can branch out into multiple streams. Generally, in the absence of multiple branches, the downstream flow is greater than the upstream flow. Therefore, based on the flow of electrical energy (analogous to water), each available power supply device can be considered a node where electrical energy converges and / or branches out. When the loads of power supply devices from multiple upstream nodes converge to the current power supply device, the load of that current power supply device can be determined by the sum of the loads of all upstream devices to which it converges. The load of the current power supply device may then flow to at least one downstream device; that is, its load can be split and distributed to various downstream devices.

[0073] Therefore, when performing load calculations, considering that the direction of load flow is opposite to the direction of power transmission, the actual load of each selectable power supply device can be obtained by accumulating the load layer by layer from the power supply device closest to the user (meaning the power supply device with the fewest connection jumpers) according to the power transmission path.

[0074] Therefore, in one embodiment of the present invention, the process of determining power supply request data may include:

[0075] Step 201: Filter the power supply request time series sent to the target power supply system according to the request processing progress to obtain the power supply request data.

[0076] In one embodiment of the present invention, considering that the target power supply system generally requires a certain time period to process power supply requests, that is, after the power supply request is input, it will enter a queue. The power supply system will approve and process the power supply requests in the queue in the order of sending time, such as supplying power after approval or refusing to supply power if the approval is not approved.

[0077] Therefore, if only the impact of the current batch of power supply requests on the load of the target power supply system is determined, even if the current capacity is below the alarm threshold, there may still be insufficient capacity leading to safety accidents in the future if there are a large number of unprocessed power supply requests in the queue. Therefore, in order to improve the safety of the target power supply system, it is possible to include all unprocessed power supply requests in the capacity calculation of the target power supply system.

[0078] Specifically, power requests that have not yet been approved can be filtered out from the power request time series based on the request processing progress to obtain power request data for load calculation. The power request time series includes power requests arranged in chronological order of their sending time.

[0079] In one embodiment of the present invention, step 20 further includes:

[0080] Step 202: Determine the transmission start device, transmission end device, and upstream power supply device corresponding to each of the multiple optional power supply devices from the power transmission path; wherein, the transmission start device is the optional power supply device directly connected to the power request sender; the transmission end device is the optional power supply device directly connected to the mains power; and the upstream power supply device is another optional power supply device that sends the power request data to the current optional power supply device.

[0081] In one embodiment of the present invention, reference is made to... Figure 2 Taking the UPS system as an example of the current optional power supply equipment, its upstream power supply equipment includes AC small busbars, AC extension cabinets and AC row head cabinets. For the UPS input distribution cabinet, the secondary low-voltage outgoing cabinet and the primary low-voltage outgoing cabinet respectively, the UPS system is one of its upstream power supply equipment.

[0082] Step 203: Starting from the transmission initiation device and ending at the transmission termination device, determine the actual load of each optional power supply device in sequence according to the actual load of the upstream power supply device corresponding to each optional power supply device.

[0083] In one embodiment of the present invention, the combination continues... Figure 2 The transmission initiation equipment includes three types: AC small busbars, AC rack-end cabinets, and DC rack-end cabinets. Multiple units of each type of transmission initiation equipment can be used. Transmission termination equipment includes... Figure 2 The primary high-voltage incoming cabinet. For example, when the optional power supply equipment is the primary low-voltage outgoing cabinet, its actual load is determined based on the actual loads of the four types of equipment: the UPS input distribution cabinet, the UPS system, the AC distribution panel, and the secondary low-voltage incoming cabinet.

[0084] In one embodiment of the present invention, step 203 further includes:

[0085] Step 210: Determine the actual load of the optional power supply device based on the sum of the actual loads of all the upstream power supply devices corresponding to the optional power supply device.

[0086] In one embodiment of the present invention, the sum of the actual loads of all the upstream power supply devices can be used as the input load of the current optional power supply device. Then, the corresponding performance index conversion and calculation are performed on the input load according to the device type of the current optional power supply device to obtain the actual load of the current optional power supply device.

[0087] Therefore, in one embodiment of the present invention, step 210 further includes:

[0088] Step 211: Determine the device type of the optional power supply device.

[0089] In one embodiment of the present invention, the device type may be a power supply device, such as a UPS system or a DC power distribution cabinet.

[0090] Step 212: Determine the actual load of each of the optional power supply devices according to the sum of the device type and the actual load.

[0091] In one embodiment of the present invention, the sum of the actual loads of all upstream devices is processed according to the device type to obtain the actual load of the current device. The processing may include determining the load calculation method based on the device type, and extracting and calculating information from the sum of the actual loads according to the load calculation method to obtain the actual load.

[0092] Step 212 also includes:

[0093] Step 2121: Determine the load performance indicators and design parameters corresponding to the optional power supply equipment according to the equipment type.

[0094] In one embodiment of the present invention, the load performance index is used to evaluate the load performance of the power supply equipment. It can be set according to national standards and the standards of suppliers and manufacturers, such as charging power, charging current, expected current and capacity utilization ratio.

[0095] Step 2122: Extract features from the sum of the actual loads based on the load performance indicators to obtain the actual indicator values.

[0096] In one embodiment of the present invention, all information included in the sum of the actual loads is extracted according to the parameters required for calculating the load performance index. The actual index value is obtained by calculating according to the calculation formula corresponding to the performance formula based on the extracted information.

[0097] Step 2123: Calculate the actual load based on the actual index value and the design parameters.

[0098] In one embodiment of the present invention, the design parameters may be design threshold values ​​for certain indicators of the optional power supply equipment, such as rated capacity, design current, etc. After obtaining the actual indicator values, the actual load is determined based on the comparison between the actual indicator values ​​and the design parameters, such as battery pack capacity utilization ratio = battery full capacity discharge test capacity / rated capacity, reserved current (load) = design current - cumulative current (load), etc.

[0099] Step 30: Determine the power capacity of the target power supply system based on all the actual loads.

[0100] In one embodiment of the present invention, the device capacity of each optional power supply device can be determined according to the actual load of each optional power supply device, and the power capacity of the target power supply system can be determined according to the device capacity of all optional power supply devices.

[0101] Specifically, the power capacity of the target power supply system can be obtained by normalizing the capacity of all available power supply equipment according to their equipment type, or by weighting and summing them according to their corresponding weights.

[0102] In another embodiment of the present invention, the power supply safety level of the target power supply system can be determined based on the power capacity of the target power supply system, and an alarm warning can be issued. The power supply safety level can be determined based on the matching result of each actual load with the corresponding equipment load threshold, or it can be determined based on the matching result of the total load of the target power supply system and the corresponding total threshold of the system.

[0103] In another embodiment of the present invention, the process of calculating the capacity of the power supply system can also be as follows:

[0104] First, the load transfer algorithm between optional power supply devices will be explained:

[0105] Considering the complex link involved in transferring load from the power supply unit to the mains, the load transfer can be split or merged based on the connection relationships between lower-level and higher-level node devices in the link. It should be noted that since the direction of load transfer is opposite to the direction of power transmission, the lower-level node device is the upstream power supply device in the aforementioned embodiment, while the upper-level node device is the currently optional power supply device that receives the load input from the upstream power supply device in the aforementioned embodiment.

[0106] Specifically, in a one-to-one relationship, the load is directly passed from the lower-level node to the upper-level node; in a one-to-many relationship, the load is split according to the different device types of the upper-level node. When multiple lower-level loads are passed to the same current node, load merging is performed at the current node. Link hierarchy description: e.g. Figure 2 As shown, the arrow starts at the lower level and points to the upper level.

[0107] Specifically, the entire link transmission process is as follows:

[0108] 1.1 Based on information from the same site, filter current electricity applications and historical electricity applications under review, and merge the electricity loads according to whether they are transmitted to the same power supply unit.

[0109] 1.2 The load from step 1.1 can be divided into three parts based on the different devices to which it is transmitted: DC rack head load, AC rack head load, and AC busbar load.

[0110] 1.3 When the DC distribution cabinet transfers load, it also splits the load according to the different connected devices at the upper level. It can be divided into two parts: the DC distribution cabinet load and the DC system load.

[0111] 1.4 When the DC distribution cabinet transfers load, it directly transfers the load to the DC system.

[0112] 1.5 Combine the loads transferred to the DC system in steps 1.3 and 1.4, and then transfer the DC system loads to the AC distribution panel.

[0113] 1.6 When the AC distribution panel transmits load, the load is split according to the different connected equipment at the upper level. It can be divided into two parts: the secondary low-voltage outgoing cabinet load and the primary low-voltage outgoing cabinet load.

[0114] 1.7 When the AC extension cabinet transfers load, it also splits the load according to the different connected devices at the upper level, which can be divided into two parts: the AC extension cabinet load and the UPS system load.

[0115] 1.8 When the AC busbar is used for load transfer, the load is directly transferred to the UPS system.

[0116] 1.9 When the AC extension cabinet is transferring load, it directly transfers the load to the UPS system.

[0117] 1.10. Combine the loads passed to the UPS system in steps 1.7, 1.8, and 1.9, and then split the loads according to the different connected devices of the UPS system. The loads can be divided into three parts: the UPS input distribution cabinet load, the secondary low-voltage outgoing cabinet load, and the primary low-voltage outgoing cabinet load.

[0118] 1.11 When the UPS input distribution cabinet transmits load, the load is split according to the different connected devices at the upstream level, and can be divided into two parts: the secondary low-voltage outgoing cabinet load and the primary low-voltage outgoing cabinet load.

[0119] 1.12. Combine the loads transferred to the secondary low-voltage outgoing cabinet in steps 1.6, 1.10, and 1.11, and then transfer the loads directly to the secondary low-voltage incoming cabinet.

[0120] 1.13 When the secondary low-voltage incoming cabinet transfers load, it directly transfers the load to the primary low-voltage outgoing cabinet.

[0121] 1.14. Combine the loads passed to the primary low-voltage outgoing cabinet in steps 1.6, 1.10, 1.11, and 1.13, and then pass the loads to the primary low-voltage incoming cabinet. If there is a primary low-voltage generator in the link, the loads need to be passed to the primary low-voltage generator at the same time.

[0122] 1.15. The primary low-pressure oil pump, as the terminal device, directly participates in capacity calculation and does not require further transmission.

[0123] 1.16 When the primary low-voltage incoming switchgear is transferring load, it directly transfers the load to the transformer.

[0124] 1.17 When a transformer transmits load, the load is split according to the different connected equipment at the upper level, and can be divided into two parts: the load of the secondary high-voltage outgoing cabinet and the load of the primary high-voltage outgoing cabinet.

[0125] 1.18 When the secondary high-voltage outgoing cabinet transfers load, it directly transfers the load to the secondary high-voltage incoming cabinet. If there is a high-voltage generator in the link, the load needs to be transferred to the high-voltage generator at the same time.

[0126] 1.19 When the secondary high-voltage incoming cabinet transfers load, it directly transfers the load to the primary high-voltage outgoing cabinet.

[0127] 1.20. Combine the loads transferred to the primary high-voltage outgoing cabinet in steps 1.16 and 1.18, and then transfer the loads to the primary high-voltage incoming cabinet. If there is a high-voltage generator in the link, the loads need to be transferred to the high-voltage generator at the same time.

[0128] 1.21. The high-pressure oil pump, as the terminal device, directly participates in the capacity calculation and does not need to be transmitted further.

[0129] 1.22. The primary high-voltage incoming switchgear, as the terminal equipment, directly participates in capacity calculation and does not require further transmission.

[0130] Next, let's discuss based on... Figure 2The algorithm for calculating the capacity of each node in a power transmission link is explained below:

[0131] Based on the similarity of device capacity calculations within the link nodes, the nodes are categorized into three types: power load query nodes, DC power supply unit nodes, and DC system nodes. Each type of node has a specific capacity calculation method tailored to its characteristics. Each link node performs multi-dimensional capacity index calculations using this method, and then determines the alarm level based on index thresholds. This provides a comprehensive overview of the current device capacity load from multiple perspectives, including the calculation methods for the following types of node devices:

[0132] 2.1 Electricity load query node:

[0133] 2.1.1 Input Data: Power Consumption Warning Information (applicationPowerUp), Data Center Information (equipmentRoom), Site Information (site)

[0134] 2.1.2 Outgoing Data: The outgoing data structure is encapsulated according to {key: [val1, val2, val3, val4]}, where the key is composed of key information from the parent node, in the form of "H or N / System Name / Device Type / Device Number / Branch Number / Terminal Number". H and N indicate whether the current device is a current or historical device; System Name indicates the system to which the current device belongs; Device Type indicates the device type of the connected lower-level node; Device Number indicates the device number of the connected lower-level node; Branch Number indicates the device branch of the connected lower-level node; Terminal Number indicates the terminal number of the connected lower-level node. val1 represents the pre-increase load of the current device, val2 represents the pre-increase current of the current device, val3 represents the charging current of the current device, and val4 represents the charging power of the current device. The final format of the outgoing data is: {H or N / System Name / Device Type / Device Number / Branch Number / Terminal Number: [Pre-increase Load, Pre-increase Current, Charging Current, Charging Power]}

[0135] It should be noted that the electricity load query node refers to the node device directly connected to the user. It is the source and starting point of the load input of the target power supply system, so the electricity load query needs to start from this point.

[0136] 2.1.3 Detailed steps for capacity calculation:

[0137] 1) Inquire about the current electricity consumption project and the historical electricity consumption projects under approval, and then search for the power supply cabinet based on the project.

[0138] 2) Define a variable mapN to store the pre-incremental load transmitted to the grid head cabinet for this power consumption. Iterate through the grid head cabinets for this power consumption, retrieve the pre-incremental load transmitted to the grid head cabinet, and accumulate the loads transmitted to the same grid head cabinet and the same branch number, and store them in the variable mapN.

[0139] 3) Define a variable mapH to store the pre-incremental loads transmitted to the grid head cabinet in history. Query the historical power consumption items and their corresponding power consumption cabinets, traverse the power consumption cabinets, retrieve the pre-incremental loads transmitted to the grid head cabinet, accumulate the loads transmitted to the same grid head cabinet and the same branch number, and store them in mapH.

[0140] 4) Compare the key of mapN with the key of mapH. Add the pre-increment load in mapH with the same key to mapN and delete the data from mapH.

[0141] 5) Merge the mapN and mapH sets and pass them to the next node.

[0147] 2) Loop through the map collection passed from the lower level to this level, query the equipment information of the DC row head cabinet according to the key of the map, and then query the corresponding upper level information of the DC row head cabinet.

[0148] 3) Determine whether the device is the one that is used for this power consumption based on whether the key contains the N flag. If it is the device used for this power consumption, the load transmitted to the DC distribution cabinet or DC distribution panel will be stored in mapN.

[0149] 4) Calculate the following capacity indicators and determine whether to interrupt subsequent capacity calculations.

[0150] <1> Retrieve from the database the equipment's design capacity, operating voltage, current, specifications, target thresholds, cable cross-section, number of cables, cable length, fixed voltage drop, and cable current carrying capacity.

[0151] <2> Design current = Design capacity / Operating voltage.

[0152] <3> Pre-increase current = Pre-increase load / Operating voltage.

[0153] <4> Current capacity = Current current * Operating voltage.

[0154] <5> Expected capacity = Current capacity + Expected increase in load.

[0155] <6> Expected current = Current current + Expected increase current.

[0156] <7> Cable voltage drop calculation current carrying capacity = S (cable cross section) * 57 * fixed voltage drop * number of cables / (2 * L (cable length)).

[0157] <8> Cable current carrying capacity = current carrying capacity of a single cable * number of cables.

[0158] <9> Design capacity load factor = Expected capacity / Design capacity.

[0159] <10> Switch load factor = expected current / specification.

[0160] <11> If the expected current is greater than or equal to the design current, interrupt subsequent capacity calculations.

[0161] <12> If the design current is greater than or equal to the specification, interrupt subsequent capacity calculations.

[0162] <13> If the design current is greater than or equal to the cable's current carrying capacity, discontinue subsequent capacity calculations.

[0163] <14> If the design current is greater than or equal to the current carrying capacity calculated by the cable voltage drop, the subsequent capacity calculation should be interrupted.

[0164] <15> Cumulative current (load) = expected capacity.

[0165] <16> Reserved current (load) = Index threshold (design capacity load rate threshold ratio * equipment design capacity) - cumulative current (load).

[0166] 5) If it is a historical electrical device, the load transmitted to the DC distribution cabinet or DC distribution panel will be stored in mapH.

[0175] 3) Iterate through the map collection passed from the lower level to this level, and query the corresponding DC system number based on the DC distribution panel information in the key. Then, based on whether the key contains the N flag, decide whether to store the pre-increase load and pre-increase current in mapSystemN or mapSystemH, thus converting the pre-increase load and pre-increase current from the DC distribution panel level to the DC system level.

[0176] 4) Loop through the mapSystemN set for this electricity consumption, and based on the system information contained in the key, query the equipment information contained in the system.

[0179] <3> Select the batteries and calculate the corresponding battery discharge test capacity = ∑(discharge test capacity of all batteries in the same DC system).

[0180] <4> Select rectifier cabinets and calculate the total current of the corresponding switching power supply modules = ∑(number of rectifier modules in all rectifier cabinets of the same DC system × rectifier module specifications).

[0181] <5> Calculate the charging current of the system = ∑(the total capacity of all battery packs in the DC system) / 10, and store it in mapSystemN.

[0182] <6> The system's charging power is calculated as charging current × battery equalization voltage, and then stored in mapSystemN.

[0183] <7> Expected current = Current current + Expected increase current.

[0184] <8> Current current switching power supply load capacity ratio = current current / total current of switching power supply module.

[0185] <9> Expected current switching power supply load capacity ratio = Expected current / Total current of switching power supply module.

[0186] <10> Battery pack capacity utilization ratio = Battery full capacity discharge test capacity / Rated capacity.

[0187] <11> Current DC system capacity ratio = Current current / Design current.

[0188] <12> Expected DC system capacity ratio = Expected current / Design current.

[0189] <13> Cumulative current (load) = Expected current.

[0190] <14> Reserved current (load) = Design current - Accumulated current (load).

[0191] 5) Based on the connection information of the DC power system, the data transmitted to the AC power distribution panel is stored in mapN. If the corresponding key exists in the set, the data is directly accumulated.

[0192] 6) Iterate through the mapSystemH set of historical power consumption data. Based on the system information contained in the key, query the device information contained in the system, iterate through the devices contained in the system, filter the battery banks, calculate the system charging current = ∑(the total capacity of all battery banks in the DC system) / 10, and store it in mapSystemH. Calculate the system charging power = charging current × battery equalization voltage, and store it in mapSystemH.

[0193] 7) Based on the upstream information of the historical DC power system, the data transmitted to the AC distribution panel is stored in mapH. If the corresponding key exists in the set, the data is directly accumulated.

[0197] 2.5 The data structure and capacity calculation process for the incoming and outgoing data of UPS system nodes, transformer nodes, and high-voltage generator nodes are the same as those in step 2.3, and will not be repeated here.

[0198] This invention addresses the issue of determining power transmission paths between multiple selectable power supply devices in a target power supply system. Each power supply device processes mains power so that it can be processed by the next level of power supply device. After processing through multiple levels of power supply devices, the power can be output to communication equipment rooms, etc. The power transmission path reflects the hierarchical relationship of the power load between the power supply devices. Based on the power request data received by the target power supply system and the power transmission path, the actual load of each selectable power supply device is calculated. The power capacity of the target power supply system is determined based on all the actual loads, thus differentiating it from the prior art where the power supply system capacity calculation is performed in a single step. Generally, calculations can only be performed on specific indicators of some core equipment. However, the power supply system is a whole, and the safety of some equipment does not represent the power supply safety of the entire system. This leads to poor accuracy in calculating the power supply system capacity. The present invention addresses this by considering the target power supply system as a whole and transmitting power request data step by step among all available power supply equipment in the system according to the power transmission path. The data is then distributed or aggregated among upstream and downstream equipment at each level, thereby obtaining the capacity of each available power supply equipment. Finally, the capacity of the entire system can be calculated from the entire process, improving the accuracy of power supply system capacity calculation and effectively ensuring the power supply safety of the communication equipment room.

[0203] The operation process of the power supply system capacity calculation device provided in this embodiment of the invention is largely the same as that of the aforementioned method embodiment, and will not be repeated here.

[0204] The power supply system capacity calculation device provided in this embodiment of the invention determines the power transmission path between multiple optional power supply devices in a target power supply system. The power supply devices process mains power so that it can be processed by the next level of power supply devices. After processing by multiple levels of power supply devices, the power can be output to communication equipment rooms, etc., for power supply. The power transmission path reflects the hierarchical relationship of the power load between the power supply devices. Based on the power request data received by the target power supply system and the power transmission path, the actual load of each optional power supply device is calculated. The power capacity of the target power supply system is determined based on all the actual loads, thus distinguishing it from the prior art in which power supply systems are calculated... Traditional capacity calculations can only be performed on specific indicators of some core equipment.

[0211] Specifically, program 510 can be called by processor 502 to cause the power supply system capacity calculation device to perform the following operations:

[0212] Determine the power transmission path between multiple optional power supply devices in the target power supply system;

[0213] The actual load of each of the optional power supply devices is calculated based on the power request data received by the target power supply system and the power transmission path.

[0214] The power capacity of the target power supply system is determined based on all the actual loads.

[0215] The operation process of the power supply system capacity calculation device provided in this embodiment of the invention is largely the same as that of the aforementioned method embodiment, and will not be repeated here.

[0216] The power supply system capacity calculation device provided in this embodiment of the invention determines the power transmission path between multiple optional power supply devices in a target power supply system. The power supply devices process mains power so that it can be processed by the next level of power supply devices. After processing by multiple levels of power supply devices, the power can be output to communication equipment rooms, etc., for power supply. The power transmission path reflects the hierarchical relationship of the power load between the power supply devices. Based on the power request data received by the target power supply system and the power transmission path, the actual load of each optional power supply device is calculated. The power capacity of the target power supply system is determined based on all the actual loads, thus distinguishing it from the prior art in which power supply systems are calculated... Traditional capacity calculations can only be performed on specific indicators of some core equipment. However, the power supply system is a whole, and the safety of some equipment does not represent the power supply safety of the entire system. This leads to poor accuracy in power supply system capacity calculation. This invention addresses this issue by considering the target power supply system as a whole and transmitting power request data step by step among all available power supply equipment in the system according to the power transmission path. The data is then distributed or aggregated between upstream and downstream equipment at each level, thereby obtaining the capacity of each available power supply equipment. Finally, the entire system capacity can be calculated from the entire process, improving the accuracy of power supply system capacity calculation and effectively ensuring the power supply safety of communication equipment rooms.

[0217] This invention provides a computer-readable storage medium storing at least one executable instruction. When the executable instruction is executed on a power supply system capacity calculation device, the power supply system capacity calculation device performs the power supply system capacity calculation method in any of the above-described method embodiments.

[0218] Specifically, the executable instructions can be used to cause the power supply system capacity calculation device to perform the following operations:

[0219] Determine the power transmission path between multiple optional power supply devices in the target power supply system;

[0220] The actual load of each of the optional power supply devices is calculated based on the power request data received by the target power supply system and the power transmission path.

[0223] The executable instructions stored in the computer storage device provided in this embodiment of the invention determine the power transmission path between multiple optional power supply devices in a target power supply system. The power supply devices process mains power so that it can be processed by the next level of power supply devices. After processing by multiple levels of power supply devices, the power can be output to communication equipment rooms, etc., for power supply. The power transmission path reflects the hierarchical relationship of the power load transmission between power supply devices. Based on the power request data received by the target power supply system and the power transmission path, the actual load of each optional power supply device is calculated. The power capacity of the target power supply system is determined based on all the actual loads, thus distinguishing it from the prior art where power is transmitted through multiple stages of power supply. Power system capacity calculations typically only target specific indicators of core equipment. However, a power supply system is a whole, and the safety of some equipment does not guarantee the overall power supply security. This leads to inaccurate capacity calculations. This invention addresses this by considering the entire target power supply system and transmitting power request data step-by-step through all available power supply devices according to the power transmission path. This involves splitting or aggregating power between upstream and downstream devices at each level, thereby obtaining the capacity of each available power supply device.
