This method and device can provide a method for automatically determining whether a distribution network's power supply radius is too long for a selected distribution network area. This method and device can improve the efficiency and accuracy of determining whether a power supply radius is too long, help reduce the errors and error probability caused by manual determination, and significantly reduce costs. A detailed description is provided below.

[0075] Example 1

[0076] See also Figure 1 , Figure 1 This is a flow chart of a method for automatically determining if a power distribution network power supply radius is too long, disclosed in an embodiment of the present invention. Figure 1 The described method can be applied to a device for automatically determining that the power supply radius of a distribution network is too long. The device can be an independent device or integrated into a power supply and distribution network system, which is not limited in the embodiment of the present invention. Figure 1 As shown, the method for automatically determining that the power supply radius of the distribution network is too long may include the following operations:

[0077] 101. Determine the target judgment area of ​​the distribution network.

[0078] In the embodiment of the present invention, first, a target determination area in the distribution network where power supply radius determination is required needs to be selected. The target determination area may be selected manually or automatically, which is not limited in the embodiment of the present invention.

[0079] 102. Determine the topology of the distribution network corresponding to the target determination area.

[0080] In the embodiment of the present invention, according to the determined target determination area, a topological structure analysis is performed on the distribution network in the target determination area to resolve the line connection path of the distribution network.

[0081] 103. Determine, based on the topological structure, a target power supply device in a target determination area and at least one connection cabinet belonging to the same power supply feeder as the target power supply device.

[0082] In an embodiment of the present invention, after determining the topological structure of the distribution network, the target power supply equipment in the distribution network and the connection cabinet belonging to the same power feeder as the target power supply equipment are determined. It should be noted that the number of connection cabinets is not limited to only one, and can be multiple.

[0083] 104. Calculate the power supply radius of the target power supply equipment based on the preset GIS map information.

[0084] In an embodiment of the present invention, based on preset GIS map information associated with the distribution network, the length of the cable segment traced upward from the feed cabinet to the outlet switch of the target power supply equipment is the power supply radius of the target power supply equipment.

[0085] 105. Determine whether the length of the power supply radius meets the preset requirements.

[0086] It can be seen that the method described in the embodiment of the present invention can provide a method for automatically determining whether the power supply radius of the distribution network in a selected distribution network area is too long, which can improve the efficiency and accuracy of determining whether the power supply radius is too long, and is conducive to reducing the errors and error probabilities caused by manual judgment, thereby greatly reducing costs.

[0087] In an optional embodiment, determining the target determination area of ​​the power distribution network may include the following operations:

[0088] Determine whether there is power supply equipment and a connection cabinet connected to the power supply equipment in the selected distribution network area;

[0089] When the judgment result is yes, it is determined whether there is an incomplete branch on the power supply feeder of the power supply equipment, wherein the incomplete branch is used to indicate that the selected power supply network area fails to include a complete power supply line of the power supply equipment;

[0090] When an incomplete branch is detected, a prompt is given to reselect the distribution network area;

[0091] When it is determined that no incomplete branch exists, the selected distribution network area is determined as the target determination area.

[0092] In an embodiment of the present invention, in order to accurately determine the target determination area, it is first determined whether there is power supply equipment and a communication cabinet connected to the power supply equipment in the selected distribution network area. When a communication cabinet exists, it means that there is at least one power supply radius in the selected distribution network area. At this time, it is determined whether there is an incomplete branch in the power supply feeder of the power supply equipment. The incomplete branch is used to characterize that the selected power supply network area fails to include the complete power supply line of the power supply equipment. When the incomplete branch exists, it means that the selected target area fails to include the complete power supply line of the target power supply equipment, and the distribution network area needs to be reselected; when the incomplete branch does not exist, the selected distribution network area can be determined as the target determination area.

[0093] It can be seen that the method described in the embodiment of the present invention can provide a way to determine the complete power supply feeder of the distribution network to accurately determine the complete power supply radius of the target power supply equipment, which can improve the accuracy of determining whether the power supply radius is too long, and is conducive to reducing the errors and error probabilities caused by manual judgment, thereby greatly reducing costs.

[0094] In yet another optional embodiment, determining the topology of the distribution network corresponding to the target determination area may include the following operations:

[0095] Determine a tree-coded distribution network topology model corresponding to the target determination area, the distribution network topology model including power supply equipment, power consumption equipment and circuit connection relationship;

[0096] According to the distribution network topology model, the distribution network architecture topology analysis is performed on the target determination area to obtain the topology structure of the distribution network corresponding to the target determination area.

[0097] In an embodiment of the present invention, a distribution network topology model is first determined. This distribution network topology model is in a tree-coded format and includes power supply equipment, power consumption equipment, and circuit connection relationships. The power supply equipment corresponds to the target power supply equipment described above, the power consumption equipment corresponds to the interconnection cabinet described above, and the circuit connection relationship corresponds to the circuit connection path between the target power supply equipment and at least one interconnection cabinet. Based on the determined distribution network topology model, a distribution network architecture topology analysis is performed on the determined target determination area to obtain the distribution network topology corresponding to the target determination area.

[0098] It can be seen that the method described in the embodiment of the present invention can perform a topological architecture analysis of the distribution network in the target judgment area through the distribution network topology model to obtain an accurate grid topology structure, which is conducive to accurately determining the complete and accurate power supply radius of the target power supply equipment, further improving the efficiency and accuracy of determining whether the power supply radius is too long, reducing the errors and error probabilities caused by manual judgment, and greatly reducing costs.

[0099] In yet another optional embodiment, determining the target power supply device in the target determination area and at least one tie cabinet belonging to the same power feeder as the target power supply device according to the topology may include the following operations:

[0100] According to the topology structure, the power supply relationship of the target power supply equipment is analyzed to obtain the power supply relationship result corresponding to the target power supply equipment;

[0101] The power supply path is tracked based on the power supply relationship results in combination with the spatial characteristics of the GIS map, and at least one contact cabinet belonging to the same power feeder as the target power supply equipment is determined.

[0102] In this embodiment of the present invention, after determining the topology of the distribution network in the target determination area, a power supply relationship analysis is performed based on this topology to obtain a power supply relationship result corresponding to the target power supply device. This power supply relationship result is used to accurately characterize the feeder line of the target power supply device. Simultaneously, the power supply relationship is further traced using a GIS map to track the actual power supply path and identify at least one contact cabinet that shares the same power feeder line as the target power supply device.

[0103] It can be seen that the method described in the embodiment of the present invention can combine the power supply relationship and GIS map information to accurately determine the target power supply equipment and the communication cabinet of the target power supply equipment in the target judgment area, which is conducive to accurately determining the complete and accurate power supply radius of the target power supply equipment, further improving the efficiency and accuracy of the judgment of excessive power supply radius, reducing the errors and error probabilities caused by manual judgment, and greatly reducing costs.

[0104] In another optional embodiment, calculating the power supply radius of the target power supply device according to preset GIS map information may include the following operations:

[0105] Calculate the trunk length between each contact cabinet and the target power supply equipment based on the preset GIS map information;

[0106] The power supply radius of the target power supply equipment is determined based on the lengths of all trunk sub-trunks.

[0107] In an embodiment of the present invention, the trunk sub-length between each communication cabinet and the target power supply equipment is calculated through GIS map information. It should be noted that when the corresponding trunk sub-length lines between the communication cabinets are repeated, deduplication processing is required to ensure that the line is calculated only once, and then all the trunk sub-lengths after deduplication processing are added together to obtain the power supply radius of the target power supply equipment.

[0108] It can be seen that the device described in the embodiment of the present invention can combine GIS map information to obtain the trunk lengths between all communication cabinets and the target power supply equipment, and automatically remove duplicates at the same time, accurately calculate the complete and accurate power supply radius of the target power supply equipment, further improve the efficiency and accuracy of determining whether the power supply radius is too long, reduce the errors and error probability caused by manual judgment, and greatly reduce costs.

[0109] Example 2

[0110] See also Figure 2 , Figure 2 This is another flow chart of automatically determining that the power supply radius of a distribution network is too long, disclosed in an embodiment of the present invention. Figure 2 The described method can be applied to a device for automatically determining that the power supply radius of a distribution network is too long. The device can be an independent device or integrated into a power supply and distribution network system, which is not limited in the embodiment of the present invention. Figure 2 As shown, the method for automatically determining that the power supply radius of the distribution network is too long may include the following operations:

[0111] 201. Determine the target determination area of ​​the distribution network.

[0112] 202. Determine the topology of the distribution network corresponding to the target determination area.

[0113] 203. Determine, based on the topological structure, a target power supply device in a target determination area and at least one connection cabinet belonging to the same power supply feeder as the target power supply device.

[0114] 204. Calculate the power supply radius of the target power supply equipment based on the preset GIS map information.

[0115] 205. Determine a power supply radius threshold of the target power supply device.

[0116] In the embodiment of the present invention, determining the power supply radius threshold of the target power supply device may include the following operations:

[0117] Determine the calculation factors and the weight coefficient corresponding to each calculation factor according to the preset power supply radius calculation model, where the calculation factors include one or more combinations of the voltage level of the target power supply equipment, user terminal density, number of power supply phases, wire type, and economic current density;

[0118] A weighted calculation is performed on the target power supply device based on all calculation factors to calculate the power supply radius threshold of the target power supply device.

[0119] In an embodiment of the present invention, the preset power supply radius calculation model includes calculation factors and weight coefficients corresponding to each calculation factor, wherein the calculation factors include one or more combinations of the voltage level of the target power supply equipment, the user terminal density, the number of power supply phases, the wire type, and the economic current density. It should be noted that the calculation factors may also include other parameters, which are not limited by the embodiment of the present invention. At the same time, the various parameters of the calculation factors can be original values ​​or unit values ​​after conversion, which are also not limited by the embodiment of the present invention. Furthermore, the target power supply equipment is weightedly calculated according to all the calculation factors, and the power supply radius threshold can be obtained.

[0120] For example, the voltage level is 10 kV (corresponding unit quantity is 1), the user terminal density is 5 unit quantities, the number of power supply phases is 3 (corresponding unit quantity is 3), the wire type is Class I (corresponding unit quantity is 2), and the economic current density is 10 unit quantities. Among them, the weight coefficients corresponding to the voltage level, user terminal density, number of power supply phases, wire type, and economic current density are 0.1, 0.2, 0.3, 0.2, and 0.2, respectively. The corresponding total unit quantity is calculated to be 4.4. According to the preset correspondence between the unit quantity and the power supply radius (km) (for example, a 1:1 correspondence), the power supply radius threshold is 4.4 km.

[0121] Further optionally, the power supply radius threshold may be pre-set. For example, if the power supply radius of the distribution network with the default voltage level of 10kV is greater than 3km, and the power supply radius of the distribution network with the default voltage level of 20kV is greater than 6km, it is judged to be too long.

[0122] 206. Determine whether the length of the power supply radius meets the preset requirements.

[0123] In the embodiment of the present invention, for other descriptions of steps 201 to 204 and step 206, please refer to the detailed description of steps 101 to 105 in the first embodiment respectively, and the embodiment of the present invention will not be repeated.

[0124] It can be seen that the method described in the embodiment of the present invention can provide a method for calculating an accurate power supply radius threshold of the target power supply equipment through multiple calculation factors to accurately determine whether the actual power supply radius of the target power supply equipment is too long, which is conducive to improving the efficiency and accuracy of determining whether the power supply radius is too long, reducing the errors and error probability caused by manual judgment, and greatly reducing costs.

[0125] In an optional embodiment, determining whether the length of the power supply radius meets a preset requirement, the method may further include:

[0126] When it is determined that the length of the power supply radius does not meet the preset requirements, the target power supply path corresponding to the power supply radius is marked on the GIS map according to the mapping relationship between the power supply path and the GIS map.

[0127] In an embodiment of the present invention, when it is determined that the length of the power supply radius does not meet the preset requirements, for example, the 10Kv power supply radius exceeds the power supply radius threshold of 4.4Km, the target power supply path of the power supply radius is marked on the GIS map according to the mapping relationship between the power supply path and the GIS map to remind the staff that this section of the line is unreasonable.

[0128] It can be seen that the method described in the embodiment of the present invention can mark abnormal lines through the mapping relationship between power supply paths and GIS maps to alert staff to unreasonable power supply lines, which is conducive to improving the user experience of the solution.

It should be noted that the automatic determination device for the power distribution network power supply radius being too long refers to the steps in the automatic determination method for the power distribution network power supply radius being too long described in Example 1 and Example 2. The detailed description will not be repeated in this embodiment.

[0135] The judgment module 305 is used to judge whether the length of the power supply radius meets the preset requirements.

[0136] It can be seen that the device described in the embodiment of the present invention can provide a method for automatically determining whether the power supply radius of the distribution network in a selected distribution network area is too long, which can improve the efficiency and accuracy of determining whether the power supply radius is too long, and is conducive to reducing the errors and error probabilities caused by manual judgment, thereby greatly reducing costs.

[0137] In an optional embodiment, if Figure 4 As shown, the device may also include:
