It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0030] Embodiment 1

[0031] Figure 1This is a flowchart of a low-voltage area topology drawing method provided according to the first embodiment of the present invention. This embodiment is applicable to the case of visually displaying the low-voltage area topology. The method can be executed by a low-voltage area topology drawing device. The low-voltage area topology drawing device can be implemented in the form of hardware and / or software. The data search system can be configured in a server or a user terminal. Figure 1 As shown, the method includes:

[0032] Step 110: Obtain a low-voltage area topology and a geographical location map corresponding to the low-voltage area topology.

[0033] Among them, the low-voltage area topology can be the topological characteristics of the low-voltage distribution network area, which can include the connection relationship and position relationship between a transformer and its electrical equipment, etc. The low-voltage area topology can be determined based on an advanced measurement extraction system or generated by using a user voltage and a distribution transformer for similar comparison. In the embodiment of the present invention, the method for generating the low-voltage area topology is not described here. The geographic location map can be an image or graph that displays geographic phenomena in two-dimensional or multi-dimensional form according to certain rules. The geographic location map can include a regional map with a low-voltage distribution network. The number of geographic location maps can be one or more, and the geographic location maps can be pre-stored.

[0034] In an embodiment of the present invention, when it is necessary to visualize the low-voltage substation topology, the pre-generated low-voltage substation topology can be read, and the geographical location map corresponding to the low-voltage substation topology can be read. It can be understood that there can be a corresponding relationship between the geographical location map and the low-voltage substation topology, and the corresponding relationship can be pre-configured by the user or determined by the actual geographical location. For example, the geographical location map is a map of city A, and the low-voltage substation topology is also generated by the electrical equipment in city A, then the geographical location map can correspond to the low-voltage substation topology. For another example, the city where the low-voltage substation is located can be obtained based on the low-voltage substation topology, and the map found according to the city can be used in the atlas as the geographical location map corresponding to the low-voltage substation topology.

[0035] Step 120: Determine the identification legend and identification line according to the topological metadata of the low voltage substation topology.

[0036] Among them, topological metadata can be a constituent element of the low-voltage area topology, each topological metadata can correspond to a user device, and the topological metadata can include information about the current user device and association information with other devices. For example, the topological metadata can include information such as the area identification information, asset number, power supply side asset number, and device attribute information of the power device. There can be one or more topological metadata in the low-voltage area topology. The identification legend and identification line can be elements for visually displaying the low-voltage area topology. The identification legend can be used to display the attribute information of each power device in the low-voltage area topology, and the identification line can be used to display the relationship information between different power devices in the low-voltage area topology.

[0037] Specifically, each topology metadata in the low-voltage substation topology can be extracted, and the corresponding identification legend can be determined based on the information identifying the attributes of the electrical equipment in the topology metadata, and the corresponding identification line can be determined based on the relationship information between different electrical equipment in the topology metadata. For example, the corresponding identification legend can be determined according to the type of electrical equipment included in the topology metadata, and the identification line can be determined based on the type of wire connected to other electrical equipment in the topology metadata. It can be understood that the type of user equipment and the type of wire are only examples and are not limited. Information such as the user type, substation, meter box type, seal type, safety hazard, etc. of the user equipment can also be used to determine the identification line or identification legend.

[0038] Step 130: Draw the identification legend and identification line on the geographic location map according to the spatial location of the topological metadata.

[0039] The spatial location may be information about the location of the electrical equipment in the real world corresponding to the topological metadata, and the spatial location may include information such as the spatial coordinates or place names of the electrical equipment.

[0040] In an embodiment of the present invention, information identifying the spatial location, such as place names or spatial coordinates, can be extracted from each topological metadata, and the information can be used to determine the area where each topological metadata corresponds to the geographical location map. An identification legend and identification lines of the corresponding topological metadata can be drawn in the area, thereby realizing the generation of low-voltage substation topology.

[0041] In an embodiment of the present invention, a low-voltage substation topology and a geographical location map corresponding to the low-voltage substation topology are obtained, identification legends and identification lines corresponding to different topology metadata in the low-voltage substation topology are determined, and the identification legends and identification lines are drawn in the geographical location map according to the spatial position of the topology metadata, thereby realizing visual drawing of the low-voltage substation topology, facilitating users to optimize and transform the low-voltage distribution network based on the low-voltage substation topology, reducing the difficulty of power grid operation and maintenance, and thus improving user experience.

[0042] Embodiment 2

[0043] Figure 2 1 is a flow chart of a method for drawing a low voltage area topology according to the second embodiment of the present invention. This embodiment is a specific implementation based on the above embodiment. Figure 2 As shown, the method includes:

[0044] Step 210: determine the low voltage area topology according to the user specified parameters, wherein the user specified parameters at least include identification information of the low voltage area topology.

[0045] Among them, the user-specified parameters can be the information of the low-voltage substation topology that the user selects to be displayed, which can be input by user voice or text information, and the identification information can be information that identifies different low-voltage substation topologies, which can include the transformer name, transformer number, power grid area name, etc.

[0046] In an embodiment of the present invention, user-specified parameters input by a user can be received, identification information of the low-voltage substation topology included in the user-specified parameters can be extracted, and one or more pre-stored low-voltage substation topologies can be read according to the identification information to perform candidate visualization drawing.

[0047] Further, based on the above-mentioned embodiments of the invention, the low-voltage substation topology includes topological metadata of at least one electrical device, and the topological metadata includes at least substation identification information, asset number, power supply side asset number and device attribute information.

[0048] In an embodiment of the present invention, the low-voltage substation topology can be composed of one or more topology metadata, and each topology metadata can correspond to an electrical equipment in a substation. Each topology metadata may include relevant information of the electrical equipment, including but not limited to substation identification information, asset number, power supply side asset number and equipment attribute information.

[0049] Step 220: Determine the power grid area corresponding to the low voltage substation topology.

[0050] The power grid area may be information identifying a low-voltage substation area, and the power grid area may specifically be a transformer substation name or a power supply area name, etc.

[0051] In the embodiment of the present invention, the grid area to which it belongs can be determined based on the information included in the low-voltage area topology. For example, the asset number of the transformer in the low-voltage area topology can be obtained, and the power supply area corresponding to the asset number can be used as the grid area.

[0052] Step 230: Search for a geographical location map corresponding to the power grid area in a preset map set.

[0053] Among them, the preset atlas can be a collection of geographical location maps of different areas of the power grid network, and the preset atlas can be divided according to different power grid areas. For example, the preset atlas can include geographical location maps of different cities, or the preset atlas can include geographical location maps of different power stations.

[0054] Specifically, a geographic location map can be searched in a preset map set according to the power grid area corresponding to the low-voltage area topology, and the found geographic location map can correspond to the low-voltage area topology. It can be understood that the preset map set can be configured by the user as needed. For example, the user can configure geographic location maps of different accuracies in the preset map set as needed.

[0055] Step 240: extract the type of electrical equipment and wire diameter included in each topology metadata in the low-voltage area topology.

[0056] The type of electric equipment may be information reflecting the type of electric equipment, and the type of electric equipment may be marked based on the type name or number, and the type of electric equipment may include a metering terminal, a concentrator, a single-phase meter, a three-phase meter, a T-junction, a pole, etc. The wire diameter may be the wire diameter of the low-voltage wire connected to the electric equipment.

[0057] In the embodiment of the present invention, the type of electric equipment and the wire diameter may be extracted from the topology metadata of the low voltage substation topology, wherein the type of electric equipment and the wire diameter may belong to the device attribute information of the electric equipment.

[0058] Step 250: Search the preset configuration file for the identification legend corresponding to the type of electrical equipment and the identification line type corresponding to the wire diameter, wherein the type of electrical equipment includes at least one of the following: single-phase meter, three-phase meter, line branch point, line inflection point, and electric pole.

[0059] The preset configuration file may be a file for determining the identification legend and the type of the identification line. The preset configuration file may include the correspondence between the identification legend and the type of electrical equipment, and the correspondence between the type of the identification line and the wire diameter. The preset configuration file may be changed according to user needs. The type of the identification line may be the type of conductive wire diameter of the electrical equipment. Figure 3 , you can use dashed or solid lines to identify different wire diameters.

[0060] In an embodiment of the present invention, a preset configuration file can be read into the memory, and the identification legend associated with the type of the electrical device and the identification line type corresponding to the wire diameter can be found in the preset configuration file. Figure 4 , different identification legends can correspond to electrical equipment of different types of electrical equipment.

[0061] Step 260: Determine the color of the marking line corresponding to the line diameter according to the preset red, yellow and blue rings.

[0062] The preset red, yellow, and blue rings may be information for determining the colors of marking lines of different line diameters. The colors in the preset red, yellow, and blue rings are determined based on the three primary colors of red, yellow, and blue. Generally, 12 main colors are provided, and adjacent hues are located in similar positions. Figure 5 , different colors in the preset red, yellow and blue rings can be configured for one type of wire diameter respectively.

[0063] Specifically, the color of the wire diameter configuration can be found in the preset red, yellow, and blue rings, and the color can be used as the identification line color. It is understandable that the preset red, yellow, and blue rings can also be set in the above-mentioned preset configuration file in the form of configuration parameters.

[0064] Step 270: The corresponding longitude and latitude coordinates in each topology metadata are used as the spatial position.

[0065] In the embodiment of the present invention, the longitude and latitude coordinates in each topology metadata may be extracted and used as device attribute information of different electrical devices. The longitude and latitude coordinates may be used as the spatial position of the corresponding user device.

[0066] Step 280: Search the image coordinates corresponding to the spatial position in the geographic location map.

[0067] The image coordinates may be the coordinates of a location in a geographical location map. Based on different types of geographical location maps, the image coordinates may be two-dimensional coordinates or multi-dimensional coordinates.

[0068] In the embodiment of the present invention, a location point corresponding to a spatial location may be searched in a geographical location map, and the two-dimensional coordinates or multi-dimensional coordinates of the location point determined by the geographical location map may be used as image coordinates.

[0069] Step 290: Draw a logo legend and a logo line corresponding to the topological metadata in the geographic location map according to the image coordinates.

[0070] Specifically, an identification legend of the topological metadata can be drawn at the corresponding position of the geographic location map according to the image coordinates, and different identification legends can be connected using identification lines corresponding to their topological metadata. It can be understood that the identification line can include the identification line type and identification line color determined by the above process.

[0071] The embodiment of the present invention determines the low-voltage substation topology corresponding to the user-specified parameters, extracts the power grid area corresponding to the low-voltage substation topology, searches for the geographical location map corresponding to the power grid area in a preset map set, extracts the power equipment type and line diameter of the topological metadata in the low-voltage substation topology, searches for the identification legend corresponding to the power equipment type and the identification line type corresponding to the line diameter in the preset configuration file, searches for the identification line color corresponding to the line diameter in the preset red, yellow and blue rings, uses the longitude and latitude coordinates in the topological metadata as the spatial position, determines the image coordinates of the spatial position in the geographical location map, draws the identification legend and identification line corresponding to the topological metadata on the geographical location map according to the image coordinates, and realizes the visual drawing of the low-voltage substation topology, which is convenient for users to optimize and transform the low-voltage distribution network based on the low-voltage substation topology, can reduce the difficulty of power grid operation and maintenance, and thus improve the user experience.

[0072] Further, based on the above-mentioned embodiment of the invention, the color of the marking line corresponding to the line diameter is determined according to the preset red, yellow and blue rings, including:

[0073] The mapping relationship between the color and the line diameter in the preset red, yellow and blue rings is extracted, wherein the colors corresponding to adjacent large and small line diameters belong to the same color group; the color corresponding to the line diameter is determined as the identification line color according to the mapping relationship.

[0074] Among them, the mapping relationship can be a correspondence between wire diameters and different colors, and the correspondence can be stored in association with the preset red, yellow, and blue rings. Wire diameters of similar thickness in the mapping relationship can belong to the same color system. For example, the mapping relationship may include: yellow corresponds to 10 square millimeters, yellow-orange corresponds to 16 square millimeters, orange corresponds to 25 square millimeters, red-orange corresponds to 35 square millimeters, red corresponds to 50 square millimeters, purple corresponds to 70 square millimeters, purple corresponds to 95 square millimeters, blue-purple corresponds to 120 square millimeters, blue corresponds to 150 square millimeters, cyan corresponds to 185 square millimeters, and green corresponds to 240 square millimeters.

[0075] In the embodiment of the present invention, the mapping relationship between the color and the wire diameter in the preset red, yellow and blue ring can be read, and the corresponding color can be determined according to the acquired wire diameter and the mapping relationship, and the color can be used as the identification line color. The colors corresponding to wire diameters of similar thickness in the preset red, yellow and blue ring are similar and can belong to the same color system.

[0076] Further, based on the above-mentioned embodiment of the invention, the identification line colors included in the preset red, yellow and blue rings correspond to at least 11 commonly used line diameters.

[0077] In an embodiment of the present invention, the preset red, yellow and blue rings may correspond to 11 commonly used wire diameters, which may include 10 square millimeters, 16 square millimeters, 25 square millimeters, 35 square millimeters, 50 square millimeters, 70 square millimeters, 95 square millimeters, 120 square millimeters, 150 square millimeters, 185 square millimeters, 240 square millimeters, etc.

[0078] In an exemplary embodiment, line and equipment identification can be visualized based on the low-voltage substation topology, and line information can be identified to distinguish wire diameters and the number of line phases, intuitively displaying line bottleneck problems; equipment information can be identified to distinguish single-phase meters, three-phase meters, line branch points, line turning points, and poles, intuitively displaying meter or user locations, and restoring the line direction that is consistent with actual site conditions to the greatest extent possible.

[0079] (1) Substation line information identification

[0080] Line information includes the size of the conductor wire diameter and the number of line phases. There are many types of actual substation wire diameters. The red, yellow, blue and cold tones are used to change in sequence to distinguish the changes in wire diameter from small to large. 11 common wire diameter specifications are set and marked with different colors. Wires of adjacent large and small wire diameters belong to the same color group to facilitate the distinction of color mutations in the substation line topology. The number of phases of the low-voltage user line in the substation is divided into single-phase power supply and three-phase four-wire power supply according to the different power supply methods. Different line types are designed to indicate the number of line phases. Solid lines are defined to indicate three-phase four-wire power supply, and dotted lines are defined to indicate single-phase power supply.

[0081] (2) Identification of equipment in the substation

[0082] The actual substation equipment includes single-phase meters, three-phase meters, distribution transformer terminals, concentrators, and T nodes used to identify line turning points, branch points, poles or street codes. Different icons are displayed for different equipment through keyword definitions, including color, shape and other designs, to visually and quickly distinguish different types of equipment. And according to actual needs, keyword icon definitions can be added to expand the icon display.

[0083] (3) Joint identification display of substation equipment and line information

[0084] According to the above-mentioned identification method, in the low-voltage topology diagram of the substation area, all the lines and equipment in the substation area are identified and connected in combination with the actual on-site information, which can clearly distinguish the diameter of each branch line, the change of the wire diameter, the equipment status of each node, accurately grasp the direction of the main line and branch line of the substation area, restore the actual low-voltage grid structure of the substation area, and draw the low-voltage substation area topology diagram as shown in the figure.
