[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] The method for inspecting distribution network lines provided in this application embodiment can be applied to, for example, Figure 1 The application environment shown includes a power distribution network, comprising at least one power distribution station 102 and multiple power distribution devices 104. The power distribution station 102 communicates with the automated power distribution devices 104 via a network. The power distribution station 102 can be implemented using a standalone computer or a cluster of multiple computers. The power distribution devices include electrical components within the power distribution network. The lines in the power distribution network can be represented using a single-line diagram. A single-line diagram is an electrical wiring diagram that uses prescribed graphics or symbols to represent the actual connection method of the main electrical components in a 10 / 20kV power distribution line, with an equivalent single line. Electrical components may include, but are not limited to, various substations, ring main units, busbars, switches, disconnectors, transformers, distributed power plants, generator trucks, and conductors. The system single-line diagram is based on the single-line diagram, combining connected lines onto a single diagram, with the dispatcher manually updating the equipment status based on reports from on-site operators; the real-time single-line diagram is based on the system single-line diagram, with the equipment status automatically updated by data uploaded from the automated distribution network equipment.

[0028] In one embodiment, such as Figure 2 As shown, a method for inspecting distribution network lines is provided, which can be applied to... Figure 1 Taking the distribution network master station as an example, the following steps are included:

[0029] Step 201: If there are no abnormal loops in the system single-line diagram of the distribution network line, check whether the system single-line diagram is consistent with the real-time single-line diagram of the distribution network line.

[0030] In a distribution network, a closed loop refers to a direct connection between at least two power sources. This can easily lead to excessive inrush current, causing equipment damage. An open loop, on the other hand, means that there is a break point between every two power sources in the distribution network, meaning that no two power sources are directly connected. This avoids the problem of excessive inrush current causing equipment damage.

[0031] Under normal circumstances, distribution network lines should operate in an open-loop state, and there should be no closed loops in the system single-line diagram. Therefore, when inspecting distribution network lines, the distribution network master station first checks for abnormal closed loops in the system single-line diagram. If an abnormal closed loop is found in the system single-line diagram, the distribution network master station directly determines that the inspection result indicates an anomaly in the distribution network line and takes corresponding measures, such as outputting alarm information. If no abnormal closed loop is found in the system single-line diagram, the distribution network master station continues with other checks.

[0032] Because the system single-line diagram is manually updated by the dispatcher based on reports from field operators, while the real-time single-line diagram is automatically updated by data uploaded from the automated distribution network equipment, inconsistencies between the system single-line diagram and the real-time single-line diagram are prone to occur. If distribution network equipment with inconsistent statuses remains undetected for an extended period, it may lead to power outages or even equipment damage. In practical applications, manual inspections can be used to eliminate inconsistencies; however, this method is relatively inefficient. Therefore, in this embodiment, upon detecting an inconsistency between the system single-line diagram and the real-time single-line diagram, the distribution network master station performs the following steps for further inspection to promptly identify the source of the inconsistency, thereby resolving the problem and ensuring the normal operation of the distribution network.

[0033] Step 202: If the system single-line diagram is found to be inconsistent with the real-time single-line diagram, the traversal tree algorithm is used to detect whether the inconsistent target distribution network equipment is on the backbone line.

[0034] Inconsistencies between the system single-line diagram and the real-time single-line diagram can include anomalies in both main trunk lines and branch lines. Main trunk line anomalies occur less frequently but have a wider impact, affecting many users and impacting planned line operations and fault handling, requiring urgent intervention. Branch line anomalies, on the other hand, occur more frequently but have a smaller impact, affecting fewer users, and can be resolved by checking the operational status of on-site equipment, allowing for planned and orderly handling. Therefore, when an inconsistency is detected between the system single-line diagram and the real-time single-line diagram, the distribution network master station can detect whether the target distribution network equipment is on the main trunk line, and then take appropriate measures based on whether the target equipment is on the main trunk line or a branch line.

[0035] The distribution network master station can detect whether a target distribution network device is on the backbone line using a traversal tree algorithm: starting from the target distribution network device, the master station traverses the system single-line diagram to find the distribution network devices connected to the target device; then, based on the found distribution network devices, it determines whether the target distribution network device is on the backbone line. It should be noted that in practical applications, other methods can also be used to detect whether a target distribution network device is on the backbone line, and this application embodiment does not limit this approach.

[0036] Step 203: If the target distribution network equipment is on the main line, the distribution network line is checked according to the system single-line diagram and the real-time single-line diagram to obtain the inspection results.

[0037] The inspection results are used to indicate whether there are any abnormalities in the distribution network lines.

[0038] If the target distribution network equipment is on the main line, it indicates that the target distribution network equipment has a significant impact on the distribution network line. Therefore, further investigation is needed to determine the cause of the inconsistency.

[0039] The distribution network master station can check for undervoltage devices and abnormal loops in the system single-line diagram, as well as for issues such as undervoltage devices and abnormal loops in the real-time single-line diagram, thereby obtaining the inspection results regarding whether there are any abnormalities in the distribution network lines. This application embodiment does not impose detailed limitations on the inspection process; it can be configured according to actual conditions.

[0040] In the above embodiments, if there are no abnormal loops in the system single-line diagram of the distribution network line, the consistency between the system single-line diagram and the real-time single-line diagram of the distribution network line is checked. If an inconsistency is detected between the system single-line diagram and the real-time single-line diagram, a traversal tree algorithm is used to detect whether the inconsistent target distribution network equipment is on the main line. If the target distribution network equipment is on the main line, the distribution network line is checked according to the system single-line diagram and the real-time single-line diagram to obtain the check result. This embodiment of the application performs multi-faceted checks on the distribution network line based on the system single-line diagram and the real-time single-line diagram, which can avoid equipment damage caused by abnormal loops, discrepancies between equipment status and actual conditions, etc. Therefore, it can improve the security of the distribution network and ensure its normal operation.

[0041] In one embodiment, such as Figure 3 As shown, the process of detecting whether inconsistent target distribution network devices are on the backbone line using the traversal tree algorithm described above may include the following steps in an embodiment of this application:

[0042] Step 301: Based on the pre-established distribution network equipment model, the traversal tree algorithm is used to determine the connection relationship of the target distribution network equipment in the system single-line diagram.

[0043] The distribution network equipment model includes at least one of the following: equipment identifier, connection point identifier, and line identifier of the target distribution network equipment.

[0044] In this embodiment of the application, a distribution network equipment model can be pre-established in the distribution network master station based on data from a Geographic Information System (GIS). The distribution network equipment model is shown in formula (1):

[0045] Ai=[ID, Node1, Node2, Line, State, Event]----------------(1)

[0046] Where Ai represents the i-th distribution network device, ID is the unique identifier of the distribution network device, Node1 and Node2 are the connection point numbers of the distribution network device, Line is the line name to which the distribution network device belongs, State is the operating status of the distribution network device, and Event is the work log number associated with the distribution network device. The value corresponding to the connection point of the 10kV bus within the substation can be set to a fixed value of 0, while the values ​​corresponding to the connection points of other distribution network devices can all be set to values ​​greater than 0. It should be noted that the parameters in the distribution network device model are not limited to those described in the above embodiment; if the distribution network device has other connection points, they can also be represented by Node.

[0047] The distribution network equipment model includes connection point numbers. Since the same number indicates a physical connection, a tree traversal algorithm can be used to find the connection point with the same connection point number as the target distribution network equipment, and then the connection relationship of the target distribution network equipment can be determined based on the found connection point.

[0048] During the search process, the distribution network master station can use the search function shown in formula (2):

[0049] y=f(x)----------------------------------------(2)

[0050] Here, f is the tree traversal function, a self-nested function; x is the input parameter, representing the connection point of the target distribution network device to be searched; and y is the output result, where y = 0 indicates that the searched connection point is connected to an in-station switch, and y = 1 indicates that the searched connection point is not connected to an in-station switch. The in-station switch is typically the incoming switch of the power station; therefore, being connected to an in-station switch can be understood as being connected to the power source.

[0051] Step 302: Determine whether the target distribution network equipment is on the main line based on the connection relationship.

[0052] After determining the connection relationship of the target distribution network equipment, the distribution network master station can determine whether the target distribution network equipment is on the main line based on whether the distribution network equipment connected to the target distribution network equipment has an in-station switch.

[0053] In one embodiment, the process of determining whether the target distribution network equipment is on the trunk line may include: if all connection points of the target distribution network equipment are connected to the substation switch, then the target distribution network equipment is determined to be on the trunk line; if at least one connection point of the target distribution network equipment is not connected to the substation switch, then the target distribution network equipment is determined not to be on the trunk line.

[0054] In determining whether the target distribution network equipment is on the main line, the distribution network master station can use the main line determination function shown in formula (3):

[0055] Y=f(Node1i)+f(Node2i)----------------------(3)

[0056] Where f is the tree traversal function in formula (2), the value of f(Node1i) indicates whether the first connection point of the i-th target distribution network device is connected to the station switch, and the value of f(Node2i) indicates whether the second connection point of the i-th target distribution network device is connected to the station switch. Since the value corresponding to the connection point of the station bus is set to 0, if the first connection point of the i-th target distribution network device is connected to the station switch, then f(Node1i) is 0; if the first connection point of the i-th target distribution network device is not connected to the station switch, then f(Node1i) can be 1. Similarly, if the second connection point of the i-th target distribution network device is connected to the station switch, then f(Node2i) is 0; if the second connection point of the i-th target distribution network device is not connected to the station switch, then f(Node2i) can be 1.

[0057] Understandably, if Y is 0, it means that all connection points of the target distribution network equipment are connected to the substation switch, thus determining that the target distribution network equipment is on the main line. If Y is 1, it means that one connection point of the target distribution network equipment is not connected to the substation switch, thus determining that the target distribution network equipment is on the branch line. If Y is 2, it means that none of the connection points of the target distribution network equipment are connected to the substation switch, thus determining that the target distribution network equipment is disconnected from the network.

[0058] In the above embodiments, based on a pre-established distribution network equipment model, a traversal tree algorithm is used to determine the connection relationship of the target distribution network equipment in the system single-line diagram; based on the connection relationship, it is determined whether the target distribution network equipment is on the main line. This application embodiment determines whether the target distribution network equipment is on the main line by using a distribution network equipment model and a traversal tree algorithm, thereby determining the scope and extent of the impact of the inconsistency between the system single-line diagram and the real-time single-line diagram, and then taking corresponding measures to ensure the normal operation of the distribution network.

[0059] In one embodiment, such as Figure 4 As shown, the process of detecting the connection relationship of the target distribution network equipment in the system single-line diagram using the above-mentioned traversal tree algorithm may include the following steps in the embodiments of this application:

[0060] Step 3011: Use a tree traversal algorithm to search for the first distribution network device connected to the target distribution network device.

[0061] Based on a pre-established distribution network equipment model, a traversal tree algorithm is used for traversal search. For example, the search function f(x) is called to traverse and search the connection points Node1i of the target distribution network equipment, obtaining the first connection point with the same number as the connection point Node1i. The first distribution network equipment to which the first connection point belongs is set B = {B1, B2, ..., Bn}, and the numbers of the second connection points on the other side of the first distribution network equipment Bi form a set N = {N1, N2, ..., Nn}.

[0062] Step 3012: Use a tree traversal algorithm to search for the second distribution network device connected to the first distribution network device.

[0063] After the first distribution network device is found, the search function f(x) is called to traverse and search the second connection point on the other side of the first distribution network device to obtain the third connection point with the same number as the second connection point, and the second distribution network devices to which the third connection point belongs are grouped into a set.

[0064] Step 3013: If the searched distribution network devices meet the preset conditions, the search ends.

[0065] Following the steps outlined above, each branch is traversed and searched to determine if the found distribution network devices meet the preset conditions. If they do not meet the preset conditions, it indicates that the branch has not ended, and the search function is repeatedly called to perform the traversal search. If the found distribution network devices meet the preset conditions, it indicates that the branch has ended, and the search for that branch is terminated.

[0066] The preset conditions include: the connection point number on the other side of the distribution network device is empty; the distribution network device is a terminal device, that is, no connection point with the same connection point number as the distribution network device can be found; the distribution network device is an intra-site gateway, and the connection point value of the distribution network device is 0.

[0067] Step 3014: Based on the search results, determine the connection relationship of the target distribution network device in the system single-line diagram.

[0068] Based on the search results, all distribution network devices connected to the target distribution network device can be identified, thereby determining the connection relationship of the target distribution network device in the system single-line diagram.

[0069] In the above embodiments, a traversal tree algorithm is used to search for the first distribution network device connected to the target distribution network device; a traversal tree algorithm is also used to search for the second distribution network device connected to the first distribution network device; the search ends when the searched distribution network devices meet preset conditions; and the connection relationship of the target distribution network device in the system single-line diagram is determined based on the search results. This embodiment uses a traversal tree algorithm, which can search for all distribution network devices connected to the target distribution network device in the system single-line diagram, thereby accurately determining the connection relationship of the target distribution network device and thus judging the impact of the target distribution network device on the distribution network line. Compared with manual inspection, the traversal tree algorithm used in this embodiment is faster, more efficient, and more accurate.

[0070] In one embodiment, if an inconsistency is found between the system single-line diagram and the real-time single-line diagram, and if the target distribution network device is determined to be on the backbone line, then the distribution network line needs to be checked according to both the system single-line diagram and the real-time single-line diagram. Figure 5 As shown, the process of checking the distribution network lines based on the system single-line diagram and the real-time single-line diagram to obtain the inspection results may include the following steps:

[0071] Step 401: Determine whether there are any devices that are underpressured in the system single-line diagram.

[0072] Among them, the under-pressure equipment is the equipment that is not properly powered.

[0073] The distribution network master station checks if there are any devices in the system single-line diagram that are not properly powered. If no devices are found to be undervoltage, it indicates that the inconsistency between the system single-line diagram and the real-time single-line diagram is not caused by device undervoltage, and the distribution network master station checks other items. If devices are found to be undervoltage, it indicates that the inconsistency between the system single-line diagram and the real-time single-line diagram may be caused by device undervoltage, and the distribution network master station executes step 402 for further investigation.

[0074] Step 402: If there are undervoltage devices in the system single-line diagram, determine whether the undervoltage devices are within the preset power outage range.

[0075] If there are devices with undervoltage in the system single-line diagram, the distribution network master station determines whether the devices with undervoltage are within the preset power outage range. If the devices with undervoltage are not within the preset power outage range, step 403 is executed; if the devices with undervoltage are within the preset power outage range, step 404 is executed.

[0076] Step 403: If the undervoltage equipment is not within the preset power outage range, then the inspection result is determined to be an abnormality in the distribution network line.

[0077] If the equipment experiencing a power outage is not within the preset outage range, it indicates that the power outage is not planned and may be caused by an abnormality. Therefore, the distribution network master station can confirm that the inspection results indicate that there is an abnormality in the distribution network line.

[0078] Step 404: If the undervoltage equipment is within the preset power outage range, then the inspection result is determined to be that the distribution network line is normal.

[0079] If the power outage of the equipment is within the preset power outage range, it indicates that the power outage is a planned power outage rather than an abnormal power outage. Therefore, the distribution network master station can confirm that the inspection result is that the distribution network line is normal.

[0080] In the above embodiments, it is determined whether there is a power failure device in the system single-line diagram; if there is a power failure device in the system single-line diagram, it is determined whether the power failure device is within the preset power outage range; if the power failure device is not within the preset power outage range, the inspection result is determined to be an anomaly in the distribution network line; if the power failure device is within the preset power outage range, the inspection result is determined to be normal in the distribution network line. This application embodiment determines the inspection result by checking for power failure and the preset power outage range, which can identify the reasons for the inconsistency between the system single-line diagram and the real-time single-line diagram, thereby taking corresponding measures to ensure the normal operation of the distribution network.

[0081] In one embodiment, such as Figure 6 As shown, after determining whether there are any undervoltage devices in the system single-line diagram, if there are no undervoltage devices in the system single-line diagram, the process of checking the distribution network lines based on the system single-line diagram and the real-time single-line diagram to obtain the inspection results may also include the following steps:

[0082] Step 501: If there is no under-pressure device in the system single-line diagram, then determine whether there is a loop closure anomaly in the real-time single-line diagram.

[0083] If no under-voltage device is found in the system single-line diagram, it indicates that the inconsistency between the system single-line diagram and the real-time single-line diagram may not be caused by device under-voltage. In this case, the distribution network master station determines whether there is a loop closure anomaly in the real-time single-line diagram. If there is a loop closure anomaly in the real-time single-line diagram, the distribution network master station executes step 502; if there is no loop closure anomaly in the real-time single-line diagram, the distribution network master station executes step 505.

[0084] Step 502: If there is a loop closure anomaly in the real-time single-line graph, check whether the loop closure duration exceeds the preset duration threshold.

[0085] If a loop closure anomaly is confirmed in the real-time single-line diagram, the distribution network master station can determine whether the anomaly is caused by operational requirements or by an inherent malfunction based on the loop closure duration. The distribution network master station checks whether the loop closure duration exceeds a preset threshold. If the loop closure duration exceeds the preset threshold, the distribution network master station executes step 503; if the loop closure duration does not exceed the preset threshold, the distribution network master station executes step 504.

[0086] The preset duration threshold can be determined based on the loop closing time required for the operation of the distribution network, and this application embodiment does not limit this.

[0087] Step 503: If the loop closing time exceeds the preset time threshold, the inspection result is determined to be an anomaly in the distribution network line.

[0088] If the loop closure time exceeds the preset time threshold, it indicates that the loop closure anomaly may be caused by an anomaly. Therefore, the distribution network master station determines that the inspection result is that there is an anomaly in the distribution network line.

[0089] Step 504: If the loop closing time does not exceed the preset time threshold, the inspection result is determined to be that the distribution network line is normal.

[0090] If the loop closure time does not exceed the preset time threshold, it indicates that the loop closure anomaly is caused by operational requirements. Therefore, the distribution network master station determines that the inspection result is that the distribution network line is normal.

[0091] Step 505: If there is no loop closure anomaly in the real-time single-line diagram, the inspection result is obtained based on whether there is a pressure loss device in the real-time single-line diagram.

[0092] If the real-time single-line diagram does not show any loop closure anomalies, it indicates that the inconsistency between the system single-line diagram and the real-time single-line diagram may not be caused by loop closure anomalies. The distribution network master station then further determines whether there are any undervoltage devices in the real-time single-line diagram. If there are undervoltage devices in the real-time single-line diagram, it indicates that the inconsistency between the system single-line diagram and the real-time single-line diagram may be caused by undervoltage devices, thus confirming an anomaly in the distribution network line. If there are no undervoltage devices in the real-time single-line diagram, it can be determined that the inconsistency between the system single-line diagram and the real-time single-line diagram is due to the system single-line diagram not being updated.

[0093] In the above embodiments, if no undervoltage device is found in the system single-line diagram, it is determined whether there is a loop closure anomaly in the real-time single-line diagram; if there is a loop closure anomaly in the real-time single-line diagram, it is checked whether the loop closure duration exceeds a preset duration threshold; if the loop closure duration exceeds the preset duration threshold, the inspection result is determined to be an anomaly in the distribution network line; if the loop closure duration does not exceed the preset duration threshold, the inspection result is determined to be normal in the distribution network line; if there is no loop closure anomaly in the real-time single-line diagram, the inspection result is obtained based on whether there is an undervoltage device in the real-time single-line diagram. This application embodiment uses the real-time single-line diagram to find the reasons for the inconsistency between the system single-line diagram and the real-time single-line diagram, thereby taking corresponding measures to ensure the normal operation of the distribution network.

[0094] In one embodiment, if the inspection result indicates an anomaly in the distribution network line, an alarm message is output. Furthermore, different alarm messages are output for distribution network line anomalies detected at different stages. For example... Figure 7 As shown, the inspection method for distribution network lines is applied to... Figure 1 Taking the distribution network master station as an example, the embodiments of this application may include the following steps:

[0095] Step 601: Detect abnormal loops in the system single-line diagram of the distribution network line; if yes, proceed to step 602; if no, proceed to step 603.

[0096] Step 602: Confirm that the inspection result shows that there is an abnormality in the distribution network line, and output the first alarm information.

[0097] The first alarm message is used to alert the user that the system's single-line diagram is abnormally looping, and its importance level is urgent.

[0098] The distribution network master station outputs the first alarm information, which can be either a pop-up alarm window or an alarm sound. This application embodiment does not limit the output method.

[0099] After the distribution network master station outputs the first alarm information, it can output the most recent closing switch operation record of the distribution network line and the title of the relevant work log. Users can verify the authenticity and cause of the alarm content based on the operation record and work log.

[0100] Step 603: Check whether the system single-line diagram is consistent with the real-time single-line diagram of the distribution network line; if yes, proceed to step 604; if no, proceed to step 605.

[0101] Step 604: Confirm that the inspection result shows the distribution network line is normal.

[0102] Step 605: Use a tree traversal algorithm to detect whether the inconsistent target distribution network equipment is on the backbone line; if not, proceed to step 606; if yes, proceed to step 607.

[0103] Step 606: Confirm that the inspection result shows that there is an abnormality in the distribution network line, and output the second alarm information.

[0126] In the above embodiments, the distribution network master station first detects abnormal loops in the system single-line diagram of the distribution network line. If an abnormal loop exists, the inspection result is determined to be an anomaly in the distribution network line, and a first alarm message is output. If no abnormal loop exists, the system single-line diagram is checked to see if it is consistent with the real-time single-line diagram of the distribution network line. If they are consistent, the inspection result is determined to be normal in the distribution network line. If they are inconsistent, a traversal tree algorithm is used to detect whether the inconsistent target distribution network device is on the trunk line. If it is not on the trunk line, the inspection result is determined to be an anomaly in the distribution network line, and a second alarm message is output. If it is on the trunk line, it is determined whether there is a voltage-loss device in the system single-line diagram. If there is a voltage-loss device in the system single-line diagram, it is determined whether the voltage-loss device is within the preset power outage range. If the voltage-loss device is not within the preset power outage range, the inspection result is determined to be an anomaly in the distribution network line, and a third alarm message is output. If the voltage-loss device is within the preset power outage range, the inspection result is determined to be normal in the distribution network line. If there is no voltage-loss device in the system single-line diagram, it is determined whether there is an abnormal loop in the real-time single-line diagram. If a loop closure anomaly is detected, the loop closure duration is checked to see if it exceeds a preset duration threshold. If the loop closure duration exceeds the preset duration threshold, the inspection result is determined to be an anomaly in the distribution network line, and a fourth alarm message is output. If the loop closure duration does not exceed the preset duration threshold, the inspection result is determined to be normal in the distribution network line. This embodiment of the application performs multi-faceted checks on the distribution network line based on the system single-line diagram and real-time single-line diagram. The checks are automatically performed by the distribution network master station, resulting in high speed, high efficiency, and better accuracy. Furthermore, alarm messages are output after anomalies are detected, facilitating user verification of the cause and appropriate handling, thereby improving the safety of the distribution network and ensuring its normal operation.
