[0040] Example 1:

[0041] like Figure 1 As shown, this embodiment provides a method for generating a power supply topology structure, including:

[0042] S101, obtaining a power supply topology structure, wherein the power supply topology structure includes node attributes of switch nodes and device nodes, the node attributes of the switch nodes include on / off signals and power supply amounts, and the node attributes of the device nodes include energized signals and power consumption.

[0043] In this embodiment, the power supply topology refers to the physical connection method and network layout between devices and switches during the process of transmitting and distributing electrical energy from the power source to end-user load devices. Devices include, but are not limited to, power supply devices and load devices. Power supply devices include, but are not limited to, high-voltage distribution equipment, low-voltage distribution equipment, transformers, UPS (Uninterruptible Power Supply), and primary and standby power supply input devices. A switch node refers to the node corresponding to a switch in the power supply topology, and a device node refers to the node corresponding to a device in the power supply topology.

[0044] Specifically, S101: obtaining a power supply topology structure, including steps S1011 to S1014:

[0045] S1011, obtain the device information, device association information, power connection configuration information, power signals and power consumption, on-off signals and power supply of all switches of all devices, among which the power connection configuration information includes the switches through which power is transmitted between the device itself and the power supply and their connection relationship.

[0046] Specifically, the device information includes location information, building name, room number and device tag, and the device association information includes an upper-link device tag and a lower-link device tag.

[0047] Specifically, the on-off signal includes one of the following: on and off, and the energized signal includes one of the following: energized and de-energized.

[0048] In this embodiment, the device association information refers to the connection relationship between the device itself and other devices. Each device that needs to access the network (i.e., join the power supply network) is assigned a network access label, and the device information management system generates its own device label for each device. After the device wiring configuration is completed, it is necessary to take a photo, scan, and upload the device label of the device itself and the device label of the connected device (including the upper and lower devices). After scanning and uploading the device label of the device itself and the device label of the connected device, the device information management system can be used to query and verify the device itself and the connected device to avoid label errors of the device itself and the connected device; if the verification is correct, the device information, device association information, live signal and power consumption of the device are obtained, and the device information, device association information, live signal and power consumption of the device are updated to the device management system; if there is an error in the verification, return to the device information management system to correct the device information (i.e., the device label of the device itself and the connected device), and take a photo, scan, upload, query and verify again.

[0049] Each device is connected to at least one switch. Therefore, after the device wiring configuration is completed, this embodiment also obtains the device's power connection configuration information and the switch's on / off signal and power supply, and uploads the power connection configuration information and the switch's on / off signal and power supply to the device information management system for storage. Figure 2 As shown, the two switches connecting the devices can be divided into switches at the power input end and switches at the power output end. According to the relationship between the devices connected to the two switches and the current, the switch at the power input end is used to control the current flowing to the current device (i.e. Figure 2 The switch at the power output is used to control the current flowing out of the current device (i.e. Figure 2 Output power in). And a device connected to a switch such as Figure 3 shown.

[0050] This embodiment takes the power supply network of a communication room including high-voltage distribution equipment, low-voltage distribution equipment, transformers, UPS, load equipment and their switches as an example, and obtains equipment information, equipment association information, power connection configuration information, live signals and power consumption of the high-voltage distribution equipment, low-voltage distribution equipment, transformers, UPS, load equipment, as well as the on-off signals and power supply of the switches of the high-voltage distribution equipment, low-voltage distribution equipment, transformers, UPS, and load equipment from the equipment information management system.

[0051] It should be noted that since a device may be a power supply directly connected to a power source or a load connected to multiple power supplies, the number of upstream and downstream devices in each device varies, leading to a varying number of upstream and downstream device tags. To address the difficulty in managing an excessive number of upstream and downstream device tags, this embodiment further consolidates these excessively large numbers of upstream and downstream device tags into upstream and downstream device group tags, respectively. These upstream and downstream device group tags are used to represent multiple upstream and downstream device tags, respectively.

[0052] S1012: Determine the switch and the device as a switch node and a device node respectively.

[0053] S1013 , determining the on / off signal and the power supply as node attributes of the switch node, and determining the energized signal and the power consumption as node attributes of the device node.

[0054] In this embodiment, high-voltage power distribution equipment, low-voltage power distribution equipment, transformers, UPS, load equipment, and their switches are respectively determined as device nodes and switch nodes. Device information, device association information, power connection configuration information, energized signals, and power consumption of the high-voltage power distribution equipment, low-voltage power distribution equipment, transformers, UPS, and load equipment are determined as node attributes of the device nodes. The on / off signals and power consumption of the switches of the high-voltage power distribution equipment, low-voltage power distribution equipment, transformers, UPS, and load equipment are determined as node attributes of the switch nodes.

[0055] S1014 , based on the device association information and the power connection configuration information, associate the device nodes and the switch nodes to generate a power supply topology.

[0056] In this embodiment, the low-voltage power distribution equipment includes but is not limited to: low-voltage power distribution equipment 1 (i.e., LVDS-Main), low-voltage power distribution equipment 2 (i.e., LVDS-UPSInput) and low-voltage power distribution equipment 3 (i.e., LVDS-UPSOutput), and the load equipment includes but is not limited to: load equipment 1 (i.e., LOAD-DB-Server), load equipment 2 (i.e., LOAD-Network-Core) and load equipment 3 (i.e., LOAD-CRAC-2) as an example. Table 1 shows the equipment association information and power connection configuration information of the high-voltage distribution equipment (i.e., HVD-1), low-voltage distribution equipment, transformer (i.e., TX-1), UPS (i.e., UPS-1), and load equipment. SW-HVD-In refers to the 10 kV vacuum circuit breaker (main incoming line switch) of HVD-1, SW-TX-HV refers to the load switch on the high-voltage side of TX-1, SW-TX-LV refers to the frame circuit breaker on the low-voltage side of TX-1, SW-LVDS-Main-In refers to the main incoming line frame circuit breaker of LVDS-Main, SW-LVDS-Feed-UPS refers to the outgoing line circuit breaker of LVDS-Main (feeding to LVDS-UPSInput), SW-LVDS-Feed-CRAC2 refers to the outgoing line circuit breaker of LVDS-Main (feeding to LOAD-CRAC-2), SW-LVDS-UPSInput-In refers to the main incoming line frame circuit breaker of LVDS-UPSInput, and SW-UPS-Input Refers to the UPS-1 input circuit breaker, SW-UPS-Output refers to the UPS-1 output circuit breaker, SW-LVDS-UPSOutput-In refers to the LVDS-UPSOutput main incoming frame circuit breaker, SW-LVDS-Feed-DBServer refers to the LVDS-UPSOutput outgoing circuit breaker (feeding power to LOAD-DB-Server), SW-LVDS-Feed-NetCore refers to the LVDS-UPSOutput outgoing circuit breaker (feeding power to LOAD-Network-Core), SW-Load-CRAC2-In refers to the LOAD-CRAC-2 main power input switch / circuit breaker, SW-Load-DBServer-In refers to the LOAD-DB-Server cabinet main input switch / circuit breaker, and SW-Load-NetCore-In refers to the LOAD-Network-Core cabinet main input switch / circuit breaker.

[0057] Table 1 Equipment association information and power connection configuration information

[0058]

[0059]

[0060] Based on the device association information and power connection configuration information of the high-voltage distribution equipment (i.e., HVD-1), low-voltage distribution equipment, transformer (i.e., TX-1), UPS (i.e., UPS-1), and load equipment, a global power supply topology is generated. Local power supply topologies can also be generated based on the building name or room number. This embodiment improves the accuracy of the power supply topology by acquiring five dimensions of data: device association information, on / off signals, energized signals, power supply, and power consumption.

[0061] Optionally, after S1012: determining the switch and the device as a switch node and a device node, respectively, and before S1014: associating the device node and the switch node based on the device association information and the power connection configuration information to generate a power supply topology, the method for generating a power supply topology further includes:

[0062] S1015 , naming the device node based on the location information, the building name, the room number, the device tag, the upstream device tag, and the downstream device tag.

[0063] In this embodiment, Figure 4 As shown, the naming information of the device node includes but is not limited to: location information (i.e. Figure 4 Location code in ), building name (i.e. Figure 4 Building name code in ), room number (i.e. Figure 4 Room number code in), device tag (i.e. Figure 4 The local device code in the Figure 4 The upper device (group) code in the Figure 4 Downlink device (group) code in ).

[0064] S1016, determine the level of the switch node corresponding to the i-th switch through which power is transmitted between the device itself and the power supply as the i-th level, and name the switch node according to the device label and the level of the switch node, where i = 1, 2, ..., N, where N represents a positive integer greater than 1.

[0065] In this embodiment, taking the power connection configuration information shown in Table 1 as an example, SW-LVDS-Main-In, SW-LVDS-Feed-UPS, and SW-LVDS-Feed-CRAC2 are all switches of the low-voltage power distribution equipment 1 (i.e., LVDS-Main). According to the switch sequence through which power is transmitted between the low-voltage power distribution equipment 1 and the power supply (i.e., power supply → switch of the high-voltage power distribution equipment → switch of the transformer → switch of the low-voltage power distribution equipment 1), it can be determined that the level of the switch node corresponding to the switch of the low-voltage power distribution equipment 1 is the third level, and then the switch node corresponding to the switch of the low-voltage power distribution equipment 1 can be named LVDS-Main-3. The naming information of the device node in this embodiment integrates the location triplet (building + room + device label) to achieve accurate mapping of the physical location and the logical node. The naming information of the switch node can directly reflect its sequential position in the power supply path, realize the explicitness of the topological path, and facilitate subsequent early warning and planning.

[0066] S102: Identify a topology anomaly in the power supply topology structure.

[0067] In this embodiment, a topological anomaly refers to an error in the topological relationship. For example, in actual conditions, the switch of low-voltage power distribution equipment 1 should be connected to the switches of low-voltage power distribution equipment 2 and low-voltage power distribution equipment 3, respectively. However, the power supply topology shows that the switch of low-voltage power distribution equipment 1 is connected to the switch of low-voltage power distribution equipment 2, and the switch of low-voltage power distribution equipment 2 is connected to the switch of low-voltage power distribution equipment 3. Therefore, in the power supply topology, there is an error in the topological relationship between the switches of low-voltage power distribution equipment 1, low-voltage power distribution equipment 2, and low-voltage power distribution equipment 3. If there is an error in the topological relationship, correspondingly, at least one of the on-off signal, power consumption signal, power supply amount, and power consumption corresponding to the topological relationship will reflect an abnormal situation. Therefore, this embodiment identifies the topological anomaly of the power supply topology by comparing the on-off signal of the switch, the relationship between the on-off signal and the power consumption signal, and the power supply amount and power consumption.

[0068] Specifically, S102: identifying a topology anomaly in the power supply topology structure, including steps S1021 to S1026:

[0069] S1021, determining whether the on / off signals of the first node and the second node are on and off in sequence, wherein the first node refers to any switch node in the power supply topology structure, and the second node refers to the switch node connected to the first node.

[0070] S1022 : In response to the on / off signals of the first node and the second node being on and off in sequence, determining that the topology abnormality includes the first node and the second node.

[0071] In this embodiment, in actual situations, the switch of the low-voltage power distribution equipment 1 is connected to the switches of the low-voltage power distribution equipment 2 and the low-voltage power distribution equipment 3, respectively. Then, the on-off signals of the switches of the low-voltage power distribution equipment 1, the low-voltage power distribution equipment 2 and the low-voltage power distribution equipment 3 should be all on, all off or on, off and off in sequence, such as Figure 5 、 Figure 6 and Figure 7 As shown, the switch of the low-voltage power distribution equipment 1 is Figure 5 、 Figure 6 and Figure 7 The upper switch in the circuit breaker, the switch of the high voltage distribution equipment 2 and the low voltage distribution equipment 3 is Figure 5 、 Figure 6 and Figure 7 The lower switch in .

[0072] In this embodiment, the first node is a switch node corresponding to the switch of the low-voltage power distribution device 3, the second node is a switch node corresponding to the switch of the low-voltage power distribution device 2, and the switch of the low-voltage power distribution device 1 is connected to the switch of the low-voltage power distribution device 2, and the switch of the low-voltage power distribution device 2 is connected to the switch of the low-voltage power distribution device 3. Figure 8 As shown, if the switches of low-voltage power distribution equipment 2 and low-voltage power distribution equipment 3 (i.e. Figure 8 The on-off signals of the switch nodes corresponding to the upper switch and the lower switch in the LV power distribution equipment are off and on in sequence. It can be concluded that there is an unreasonable phenomenon in the transmission of power between the switch nodes corresponding to the switches of the low-voltage power distribution equipment 1, the low-voltage power distribution equipment 2 and the low-voltage power distribution equipment 3, that is, power is transmitted on the line where power cannot be transmitted. Therefore, there must be an error in the topological relationship between the switch nodes corresponding to the switches of the low-voltage power distribution equipment 2 and the low-voltage power distribution equipment 3.

[0073] S1023, determining whether the power signal of the third node and the on / off signal of the fourth node are energized and off in sequence, wherein the third node refers to any device node in the power supply topology structure, and the fourth node refers to the switch node connected to the third node.

[0074] S1024 , in response to the energized signal of the third node and the on / off signal of the fourth node being energized and off in sequence, determining that the topology abnormality includes the third node and the fourth node.

[0075] In this embodiment, similarly, there is an error in the topological relationship between the switch nodes corresponding to the switches of the low-voltage power distribution equipment 2 and the low-voltage power distribution equipment 3. If the on-off signal of the switch of the low-voltage power distribution equipment 2 is off, then there is no power transmission in the line between the switch of the low-voltage power distribution equipment 2 and the low-voltage power distribution equipment 2. Therefore, the energized signal of the low-voltage power distribution equipment 2 should be de-energized. If the energized signal of the low-voltage power distribution equipment 2 is energized, there must be an error in the topological relationship between the device nodes and switch nodes corresponding to the low-voltage power distribution equipment 2 and its switches.

[0076] S1025 , determining whether the power difference between the power supply of the first node and the power consumption of the fifth node is greater than a preset value, where the fifth node refers to all device nodes connected to the first node.

[0077] S1026 : In response to the difference in power supply of the first node and power consumption of the fifth node being greater than a preset value, determining that the topology abnormality includes the first node and the fifth node.

[0078] In this embodiment, taking the example that the on-off signal and the energized signal of the low-voltage power distribution equipment 1 and its switch are both on and energized, the difference in power between the power supply of the switch of the low-voltage power distribution equipment 1 and the power consumption of the low-voltage power distribution equipment 1 should be within the power loss range (that is, less than or equal to the preset value). If the power supply of the switch of the low-voltage power distribution equipment 1 is 145,000 and the power consumption of the low-voltage power distribution equipment 1 is 45,000, it can be seen that the difference in power between the power supply of the switch of the low-voltage power distribution equipment 1 and the power consumption of the low-voltage power distribution equipment 1 is not within the power loss range. Obviously, there are other devices in the switch of the low-voltage power distribution equipment 1.

[0079] If the switches of low-voltage distribution equipment 1, low-voltage distribution equipment 2 and low-voltage distribution equipment 3 in the power supply topology are all switch A, the power supply of switch A is 145000, and the power consumption of low-voltage distribution equipment 1, low-voltage distribution equipment 2 and low-voltage distribution equipment 3 are 14469, 189562 and 5962 respectively, it is obvious that there is an error in the topological relationship between the device nodes corresponding to low-voltage distribution equipment 1, low-voltage distribution equipment 2 and low-voltage distribution equipment 3 and the switch node of switch A.

[0080] It should be noted that, if in actual conditions, the connection relationship, on-off signal, and energized signal of the low-voltage power distribution equipment 1, low-voltage power distribution equipment 2, and low-voltage power distribution equipment 3 and their switches are consistent with those shown in the power supply topology, and the relationship between the power supply and the power consumption is normal, then there is no topological anomaly in the power supply topology. If the on-off signals of the switch nodes corresponding to the switches of the low-voltage power distribution equipment 1 and the low-voltage power distribution equipment 2 in the power supply topology without topological anomaly are on and off in sequence, then a power supply anomaly alarm is issued for the switches of the low-voltage power distribution equipment 1 and the low-voltage power distribution equipment 2; if the energized signals and on-off signals of the device nodes and switch nodes corresponding to the low-voltage power distribution equipment 1 and its switches in the power supply topology without topological anomaly are de-energized and on in sequence, then a power supply anomaly alarm is issued for the low-voltage power distribution equipment 1 and its switches.

[0081] S103 , performing topology correction on the topology anomaly of the power supply topology structure to obtain a target power supply topology structure.

[0082] In this embodiment, a correct topology relationship is obtained by performing a topology relationship check on the topology anomaly of the power supply topology structure; and then, based on the correct topology relationship, a topology correction is performed on the topology anomaly of the power supply topology structure to obtain a target power supply topology structure.

[0083] Specifically, S103: performing topology correction on the topology anomaly of the power supply topology structure to obtain the target power supply topology structure, including steps S1031 to S1033:

[0084] S1031, in response to the topology anomaly including the first node, the switch corresponding to the first node is connected to a dummy load with a preset power consumption, and the switch node corresponding to the switch whose power supply increment is equal to the preset power consumption is determined as the switch node connected to the first node in the target power supply topology structure.

[0085] In this embodiment, the topological relationship between the switch nodes corresponding to the switches of the low-voltage power distribution equipment 2 and the low-voltage power distribution equipment 3 is wrong as an example. Figure 9 As shown, the switch of the low voltage distribution equipment 3 (ie Figure 9 The corresponding lower-level switch in the low-voltage power distribution equipment 1 is connected to a dummy load with a preset power consumption, and the power supply increment of the switch of the low-voltage power distribution equipment 1 is found to be equal to the preset power consumption. The switch node corresponding to the switch of the low-voltage power distribution equipment 1 is corrected to the switch node connected to the upper link of the switch node corresponding to the switch of the low-voltage power distribution equipment 1.

[0086] S1032, in response to the topology anomaly including the third node, a dummy load with a preset power consumption and a device corresponding to the third node are connected in parallel, and the switch node corresponding to the switch whose power supply increment is equal to the preset power consumption is determined as the switch node connected to the third node in the target power supply topology structure.

[0087] In this embodiment, the topological relationship between the device nodes and switch nodes corresponding to the low-voltage power distribution equipment 2 and its switches is wrong as an example. Figure 10 As shown, a dummy load with preset power consumption and a low-voltage power distribution device 2 (i.e. Figure 10 A single device in the low-voltage power distribution device 2), find the switch node corresponding to the switch whose power supply increment is equal to the preset power consumption, and determine the switch node corresponding to the switch whose power supply increment is equal to the preset power consumption as the switch node connected to the low-voltage power distribution device 2.

[0088] S1033, in response to the topology anomaly including the fifth node, a dummy load with a preset power consumption and a device corresponding to the sixth node are connected in parallel, and the switch node corresponding to the switch whose power supply increment is equal to the preset power consumption is determined as the switch node connected to the sixth node in the target power supply topology structure, wherein the sixth node refers to any device node in the fifth node.

[0089] In this embodiment, low-voltage power distribution equipment 1, low-voltage power distribution equipment 2 and low-voltage power distribution equipment 3 are taken as examples. Figure 11 As shown, the dummy loads with preset power consumption and the low-voltage power distribution equipment 1, low-voltage power distribution equipment 2 and low-voltage power distribution equipment 3 (i.e. Figure 11 A single device in the circuit), find the switch node corresponding to the switch whose power supply increment is equal to the preset power consumption, and determine the switch nodes corresponding to the switch whose power supply increment is equal to the preset power consumption as the switch nodes connected to low-voltage distribution equipment 1, low-voltage distribution equipment 2 and low-voltage distribution equipment 3 respectively.

[0090] This embodiment provides a method for generating a power supply topology structure. By using on / off signals, power supply, energized signals, and power consumption, a three-level error correction mechanism is constructed for switch state conflict detection, abnormal power consumption device detection, and power supply-power consumption imbalance detection. This mechanism can comprehensively identify topology anomalies and then comprehensively correct the power supply topology structure, thereby improving the accuracy of the power supply topology structure and accurately and effectively generating the power supply topology structure.

[0091] Example 2:

[0092] like Figure 12 As shown, this embodiment provides a method for early warning of power supply anomalies. The method for early warning of power supply anomalies includes:

[0093] S201 , obtaining a target power supply topology structure, wherein the target power supply topology structure includes node attributes of switch nodes and device nodes, the node attributes of switch nodes include on / off signals and power supply amounts, and the node attributes of device nodes include energized signals and power consumption.

[0094] It should be noted that obtaining the target power supply topology specifically includes: taking the power supply network of the communication room including high-voltage distribution equipment, low-voltage distribution equipment, transformers, UPS, load equipment and their switches as an example, obtaining the equipment information, equipment association information, power connection configuration information, live signals and power consumption of the high-voltage distribution equipment, low-voltage distribution equipment, transformers, UPS, load equipment, as well as the on-off signals and power supply of the switches of the high-voltage distribution equipment, low-voltage distribution equipment, transformers, UPS, and load equipment from the equipment information management system.

[0095] High-voltage power distribution equipment, low-voltage power distribution equipment, transformers, UPS, load equipment, and their switches are identified as device nodes and switch nodes, respectively. Device information, device association information, power connection configuration information, live signals, and power consumption of high-voltage power distribution equipment, low-voltage power distribution equipment, transformers, UPS, and load equipment are identified as device node attributes. On / off signals and power consumption of the switches of high-voltage power distribution equipment, low-voltage power distribution equipment, transformers, UPS, and load equipment are identified as switch node attributes.

[0096] A global power supply topology is generated based on the device association information and power connection configuration information of high-voltage distribution equipment (i.e., HVD-1), low-voltage distribution equipment, transformer (i.e., TX-1), UPS (i.e., UPS-1), and load equipment. A local power supply topology can also be generated based on the building name or room number.

[0097] A topological anomaly refers to an error in the topological relationship. For example, in actual situations, the switch of low-voltage distribution equipment 1 should be connected to the switches of low-voltage distribution equipment 2 and low-voltage distribution equipment 3, respectively. However, the power supply topology shows that the switch of low-voltage distribution equipment 1 is connected to the switch of low-voltage distribution equipment 2, and the switch of low-voltage distribution equipment 2 is connected to the switch of low-voltage distribution equipment 3. Therefore, in the power supply topology, there is an error in the topological relationship between the switches of low-voltage distribution equipment 1, low-voltage distribution equipment 2, and low-voltage distribution equipment 3. If there is an error in the topological relationship, correspondingly, at least one of the on-off signal, power consumption signal, power supply amount, and power consumption corresponding to the topological relationship will reflect an abnormal situation. Therefore, this embodiment identifies the topological anomaly of the power supply topology by comparing the on-off signal of the switch, the relationship between the on-off signal and the power consumption signal, and the power supply amount and power consumption.

[0098] S202: Identify power supply anomalies in the target power supply topology.

[0104] S2024 , in response to the energized signal of the third node and the on / off signal of the fourth node being de-energized and on in sequence, determining that the power supply abnormality includes the third node and the fourth node.

[0105] S203: Issue an abnormality warning for power supply abnormality of the target power supply topology.

[0106] In this embodiment, if in actual conditions, the connection relationship, on-off signal, and energized signal of the low-voltage power distribution equipment 1, low-voltage power distribution equipment 2, and low-voltage power distribution equipment 3 and their switches are consistent with those shown in the power supply topology, and the relationship between the power supply and the power consumption is normal, then there is no topological anomaly in the power supply topology. If the on-off signals of the switch nodes corresponding to the switches of the low-voltage power distribution equipment 1 and the low-voltage power distribution equipment 2 in the power supply topology without topological anomaly are on and off in sequence, then a power supply anomaly alarm is issued to the switches of the low-voltage power distribution equipment 1 and the low-voltage power distribution equipment 2; if the energized signals and on-off signals of the device nodes and switch nodes corresponding to the low-voltage power distribution equipment 1 and its switches in the power supply topology without topological anomaly are de-energized and on in sequence, then a power supply anomaly alarm is issued to the low-voltage power distribution equipment 1 and its switches.
