Description

Technical Field

[0001] The present invention relates to the technical field of circuit mapping, and in particular to an automatic mapping method and system for a secondary circuit digital model. Background Art

[0002] The process layer secondary circuits of the protection and automation devices in the smart substation are physically connected through optical fibers, and the information exchange between devices is realized by virtual terminal circuits. At present, the process layer network of the smart substation uses optical fiber networking extensively, and the normal communication of the optical fiber network is a prerequisite for the normal operation of the secondary equipment. Due to the complexity of the optical fiber network and the non-standard optical fiber identification, it is difficult to ensure that the optical fiber can be correctly networked according to the design requirements during the project implementation. When problems are found or inspections are carried out, the corresponding optical fiber cannot be quickly found and relevant information cannot be viewed. Smart substations use optical fiber connections to transmit digital messages (except for tripping circuits), and the "visible" and "tangible" secondary circuits of conventional stations become "invisible" and "intangible" virtual circuits. In addition, the secondary circuits of substations mostly use number plates to indicate the voltage circuit number, current circuit number, outlet circuit number and terminal number, and express the circuit principle and wiring through corresponding paper drawings for construction commissioning and operation and maintenance operations. With the construction and operation and maintenance of smart substations, the following problems exist in the commissioning, operation and maintenance of relay protection in smart substations:

[0003] In various stages of infrastructure construction, commissioning, operation and maintenance, renovation and expansion, there are many optical fibers, little information on conventional labels, many types of drawings, large search workload, and easy loss. For conventional substations, on-site operators mainly look for corresponding circuits in the drawings by flipping through the label information. Due to the small space in the panel cabinet, various number plates and cable plates are easily squeezed and deformed, which brings great inconvenience to the on-site work; for smart substations, on-site operators need to use various tool software to find the principles and details of the secondary circuit in the SCD file and virtual terminal diagram, which is inefficient and very easy to make mistakes, seriously affecting the work efficiency of the operators. Summary of the invention

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a method for automatically drawing a secondary circuit digital model, the method comprising steps S101 to S104, wherein:

[0044] Step S101: acquiring multiple types of secondary design original files related to the substation, and extracting area division information from the secondary design original files, so as to acquire a first area filled with drawing information according to the area division information;

[0045] It should be noted that in this step, the original files of the secondary design include six categories, namely, substation room panel layout, panel cabinet layout, cabinet component diagram, device backplane diagram, terminal strip diagram, and secondary schematic diagram. In order to extract the area division information, it is necessary to compare and analyze the characteristics of these six types of frames. The substation room panel layout frame, panel cabinet layout frame, cabinet component diagram frame, device backplane diagram frame and secondary schematic diagram frame can share one frame. The terminal strip diagram frame needs to use a different frame because the drawing height requirements are significantly different from other drawings.

[0046] In addition, in some embodiments, the frame recognition is performed on each type of secondary design original file to obtain the frame coordinate information of each secondary design original file, and five first areas are delineated according to the frame coordinate information, and the five first areas are respectively used to fill in the description of the cabinet to which the drawing belongs and the name of the drawing type, the description of the substation to which the drawing belongs, the drawing number, the drawing page number, and the number of drawing pages. The description of the cabinet to which the drawing belongs is obtained through the desc description attribute value of the Cubicle element in the substation physical configuration description file, and the description of the substation to which the drawing belongs is obtained through the desc description attribute value of the Substation element in the substation physical configuration description file. The drawing number is filled in according to V1.00 by default, the page number increases sequentially starting from the number 01, and the number of pages is filled in according to the total number of drawings. For example, Figure 2 shown.

[0047] Step S102: creating symbol libraries corresponding to the types of the secondary design original files respectively, wherein the symbol libraries include a symbol library for the layout diagram of a substation room, a symbol library for the layout diagram of a panel cabinet, a symbol library for the components in a cabinet, a symbol library for the back panel diagram of a device, a symbol library for the terminal block diagram, and a symbol library for the secondary schematic diagram, and any of the symbol libraries includes at least one symbol;

[0048] like Figure 3 As shown, regarding the creation of a small room screen layout symbol library, it includes small room symbols and screen cabinet symbols; regarding the typical screen cabinet layout diagram, the creation of a screen cabinet layout symbol library is completed, which includes the screen cabinet front cabinet symbol, screen cabinet rear cabinet symbol, equipment symbols and various component symbols; regarding the typical cabinet component diagram, the creation of the cabinet component diagram symbol library is completed, which includes air switch symbols, pressure plate symbols, button symbols and handle symbols, etc.; regarding the typical device backplane diagram, the creation of the device backplane diagram symbol library is completed, which includes board symbols, board optical port symbols, board network port symbols and board terminal symbols; regarding the typical terminal strip diagram, the creation of the terminal The creation of a diagram symbol library includes terminal block symbols, single-layer terminal block one-piece terminal symbols and double-layer terminal block one-piece terminal symbols; the creation of a secondary schematic symbol library is completed for typical secondary schematics, which includes AC current analog sampling symbols, AC voltage analog sampling symbols, DC current analog sampling symbols, DC voltage analog sampling symbols, switch input symbols, normally open node switch output symbols, normally closed node switch output symbols, RS232 serial port symbols, RS485 serial port symbols, relay coil symbols, normally open contact symbols, normally closed contact symbols and resistor symbols, etc.

[0049] In addition, it should be noted that symbols include electronic component symbols and device symbols, and the electronic component symbols or the device symbols include graphic information and text information, the graphic information includes graphic shape and graphic type, and the text information includes text content corresponding to the graphic shape and coordinate information of the text content. Exemplarily, the graphic shape refers to a graphic composed of lines such as straight lines, circles, and arcs, and each combination of graphic shapes will define a coordinate insertion point. The graphic type refers to the meaning represented by the graphic, such as: relay node graphic type, relay coil graphic type, and resistor graphic type; the text content refers to the name or number of the meaning represented by the graphic shape, and the coordinate information of the text content refers to the position of the starting point of the lower left corner of the text relative to the center point of the graphic shape.

[0050] Step S103: obtaining a substation physical configuration description file, and disassembling the substation physical configuration description file level by level, wherein the disassembly result includes multi-level element names;

[0051] In this step, the substation physical configuration description file used is in XML file format, which describes the equipment configuration diagram, schematic diagram, and wiring diagram of the secondary panel cabinet or secondary equipment, and includes the physical capabilities of the equipment such as boards and ports, as well as the design configuration files for the physical connections between the wiring terminals in the electrical equipment.

[0052] By disassembling the configuration file level by level, we can get the multi-level element names, such as Figure 4 As shown in the figure, each level of elements includes: a Substation element and a PartTemplates element; a Substation element contains one or more Region elements and Bay elements; a Region element contains one or more Cubicle elements; a Bay element contains one or more Cable elements and references to multiple DeviceRef elements; a Cable element contains zero or more Core elements; a Cubicle element represents a cabinet, and the cabinet element contains one FunctionArea element, one or more DeviceRef elements, and a FunctionArea element. e (device or component), one or more Core elements; Device elements contain one or more Part (component) elements; Part elements contain zero or more Pin (connection point) elements and Component (component) elements; PartTemplates (component template library) is a collection of PartTemplate elements, containing one or more PartTemplate (component template) elements; PartTemplate elements represent the template of a certain model of components, and PartTemplate elements contain zero or more PinTemplate (connection point template) elements and ComponentTemplate (component template) elements.

[0053] Step S104: configuring at least one first-level element name for each type of secondary design original file based on the preset drawing rule, and calling corresponding symbols from the symbol library according to the configured at least one first-level element name, and determining the coordinate position of each symbol according to the preset origin selection rule, and generating a layout diagram according to the first area and the coordinate position of each symbol

[0054] It should be noted that if the drawing to be drawn is a small room screen layout diagram, the screen cabinet elements are matched according to the screen cabinet symbols to obtain the first attribute value and the second attribute value in the screen cabinet elements according to the matching results, and the first attribute value includes the screen cabinet depth value and the screen cabinet width value, and the second attribute value includes the coordinate information of the screen cabinet; then, the depth dimension and width dimension in the required generated drawing are instantiated according to the screen cabinet depth value and the screen cabinet width value, and the placement position of the screen cabinet in the required generated drawing is calculated according to the coordinate information of the screen cabinet.

[0055] If a cabinet layout diagram is drawn, the cabinet height and cabinet width of the front cabinet symbol and the rear cabinet symbol in the cabinet layout diagram are instantiated according to the value of the height (cabinet height) attribute and the width (cabinet width) value of the Cubicle (cabinet) element; the height and width of the device symbol and each component symbol in the cabinet layout diagram are instantiated according to the value of the height (device or component height) attribute and the width (device or component width) attribute of the Device (device or component) element; the actual placement position of the device or component in the cabinet is calculated according to the value of the horizontalCoordinate (relative position horizontal coordinate within the same cabinet) attribute and the verticalCoordinate (relative position vertical coordinate within the same cabinet) attribute of the Device (device or component) element.

[0056] If the component diagram inside the cabinet is drawn, the values ​​in each component symbol in the component diagram inside the cabinet are instantiated according to the value of the name (the number of the device or component in the panel cabinet) attribute and desc (device or component description) of the Device (equipment or component) element, the value of the no (terminal or connection point number) attribute of the Port (terminal) element, and the number of the opposite connection terminal retrieved from the Core (internal connection) element.

[0057] If the device backplane diagram is drawn, the values ​​in the board symbol, board port symbol and board terminal symbol in the device backplane diagram are instantiated according to the value of the name attribute (the number of the device or component in the panel) of the Device (equipment or component) element, the value of the slot attribute (board or sub-component number) of the Board (board) element, the value of the no (terminal or connection point number) attribute of the Port (terminal) element, and the number of the opposite connection terminal retrieved from the Core (internal connection) element.

[0058] If the terminal strip diagram is drawn, the terminal strip symbols and terminal strip terminal symbols in the terminal strip diagram are instantiated according to the value of the name (number of the device or component in the panel cabinet) attribute of the Device (equipment or component) element, the value of the slot (board or sub-component number) attribute of the Board (board) element, the value of the no (terminal or connection point number) attribute of the Port (terminal) element, the opposite side connection terminal number retrieved from the Core (internal connection) element, and the connection information of the terminal retrieved from the Cable (cable) element. If the secondary schematic logic drawing is drawn, the values ​​of each electronic component symbol are instantiated according to the values ​​of the attributes under the Cable (cable) element and the Core (cable core) element, the number of connecting lines in the secondary schematic is calculated according to the number of Core (cable core) elements, and the values ​​of each symbol are instantiated according to the ComponentTemplate (component template) element.

[0059] In addition, in some embodiments, the position of each symbol is the basis for realizing two-dimensional automatic mapping, but there are currently few methods and tools that can directly generate location files, and there is also a lack of guiding specification files for defining location files. It is extremely difficult to manually fill in location files. This embodiment defines the substation two-dimensional location file modeling, which includes a Substation element; the Substation element includes one or more Region elements; the Region element includes one or more Cubicle elements; the Cubicle element includes one or more Devices.

[0060] The coordinate calculation method of the substation room panel layout diagram is to use the upper left corner of the room as the two-dimensional coordinate reference origin. The upper left corner of the panel cabinet in the room is used as the relative two-dimensional coordinate calculation point after the panel cabinet is placed. The position of the panel cabinet can be defined by three elements: the shaftDirection element of the panel cabinet door direction attribute, the horizontalCoordinate element of the horizontal coordinate attribute, and the verticalCoordinate element of the vertical coordinate attribute.

[0061] The method for calculating the position coordinates of equipment or components on the panel cabinet layout diagram is to calculate them according to the cabinet symbol in front of the panel cabinet and the cabinet symbol in back of the panel cabinet respectively, with the upper left corner of the panel cabinet as the reference origin of the two-dimensional coordinates. The equipment or components in the panel cabinet take a point on the symbol as the relative two-dimensional coordinate calculation point based on the defined equipment symbol and each component symbol. The calculation points are defined differently according to the different graphic shapes that make up the symbols. Generally, there are three definition methods: take the upper left corner of the largest outer frame as the relative two-dimensional coordinate calculation point, take the top center of the largest outer frame as the relative two-dimensional coordinate calculation point, or take the exact center of the graphic shape as the relative two-dimensional coordinate calculation point.

[0062] After the input of the location file and the substation physical configuration description file is completed, drawings can be generated intelligently. The number of drawings is generated by calculation: according to the number of Region elements contained in the substation Substation element, the number of substation room layout drawings that need to be drawn is obtained; according to the number of Cubicle elements contained in the Region element, the number of cabinet layout drawings that need to be drawn is obtained; according to the number of Device (when representing components) in the Cubicle element, the number of component drawings in each cabinet is obtained, and it is stipulated that if the number of a certain component exceeds the frame area, the large number of components will be drawn separately, for example, if the number of pressure plates exceeds 27, a separate drawing will be created; according to the number of Device (when representing equipment) in the Cubicle element, the number of device backplane drawings that need to be drawn is obtained; according to the position of the terminal row, the left terminal row diagram and the right terminal row diagram are drawn, and the terminal row that exceeds the frame area is stipulated to be drawn separately; according to the FunctionArea element, the circuit type is divided to obtain the number of secondary schematics.

[0063] According to the determined number of drawings, the drawing frames in the drawing frame library are called, and the values ​​of the reserved areas of the drawing frames are instantiated and filled in according to the corresponding attribute values ​​in the substation physical configuration description file. The drawing page number and the number of drawing pages are calculated based on the total number of drawings.

[0064] The symbols in the symbol library are called according to the location file, placed according to the location coordinates, and the text content in the symbol is instantiated and filled in according to the corresponding attribute values ​​in the substation physical configuration description file.

[0065] Take the generation of terminal strip diagram as an example to illustrate. According to the above process, each symbol in the terminal strip diagram is instantiated according to the physical configuration description file of the substation, including the terminal strip name taking the name attribute value of the Device element, the terminal strip description taking the desc attribute value of the Device element, the terminal strip terminal number taking the name attribute value of the SubDevice, the terminal strip terminal description taking the desc attribute value of the SubDevice, and the inter-cabinet cable taking the attribute values ​​of the Cable element and the Core element. The terminal strip symbol is instantiated as follows: Figure 5 shown.

[0066] The present invention constructs a secondary cable and optical cable loop model with a full-loop display function, and adopts a substation secondary electrical loop modeling method to model the traditional secondary electrical loop drawing information, so that operation and maintenance personnel no longer need to rely on paper drawings for related maintenance and troubleshooting work, such as troubleshooting secondary electrical loop faults, and directly view the secondary loop diagram through a model file visualization tool, thereby replacing the traditional method of searching for the principles and details of the secondary circuit in SCD files and virtual terminal diagrams through various tool software, thereby greatly improving the work efficiency of operation and maintenance personnel.
