Description

Technical Field

[0001] This invention belongs to the field of substation monitoring and visualization technology, and relates to a method for visualizing monitoring data of prefabricated substations. Background Technology

[0002] Visualizing monitoring data from prefabricated substations is an important manifestation of enterprise digital transformation. However, key issues include how to establish the associated attributes of electrical vector diagrams and how to quickly achieve data interaction between monitoring data and visualized elements.

[0003] Based on this characteristic, the relationships between visual elements in electrical vector diagrams are typically established by reading the visualization element association relationships defined in third-party files. When sensing data interacts with visual elements, the monitoring data addresses are first processed through relationship mapping before being pushed to the visual elements. This method of establishing electrical element association relationships largely depends on the level of human expertise and lacks the versatility for batch-establishing visual element association relationships in electrical vector diagrams. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a method for visualizing monitoring data of prefabricated substations, so as to solve the problem of visualizing electrical vector diagrams and sensing data of prefabricated substations. This method simplifies the establishment of the association relationship between graphic elements in the electrical vector diagrams, and establishes a binding relationship between monitoring data and visualized graphic elements before data interaction, thereby improving the timeliness of interaction between monitoring data and visualized graphic elements.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for visualizing monitoring data from a prefabricated substation includes the following steps:

[0007] S1: Add the required visual elements and edit the relevant attributes in the electrical vector diagram of the box-type substation according to the layer order, build the binding relationship between the monitoring object and the monitoring data, and form a visual information table by the binding relationship and the electrical vector diagram.

[0008] In step S1, the required visual elements are added in layer order, introducing the concept of layers and standardizing the layer space position of each visual element, as well as the editable attributes of different elements.

[0009] In step S1, a visualization information table is formed, which records the binding relationship between the monitored object elements and the monitoring data, as well as the electrical vector diagram information. Information on elements in the electrical vector diagram that need to be changed is added through the visualization information table.

[0010] S2: Synchronize the changed information in the visualization information table to the electrical vector diagram, and save the monitoring data addresses required for sensing data interaction as address set J.

[0011] S3: Establish the association relationship of visual elements: In the electrical vector diagram, the switching equipment elements and the circuit elements establish a many-to-one association relationship based on their positional relationship; the circuit elements and the monitoring object elements establish a one-to-many association relationship based on the relevant element attributes of the circuit elements; the main circuit elements and the branch circuit elements establish a one-to-many association relationship based on the electrical transmission relationship.

[0012] S4: When interacting with the sensing data and the visual elements, parse the sensing data recorded in the address set J, update the data of the monitoring object elements of the electrical vector diagram, and dynamically update the status of the electrical elements according to the established association relationship of the visual elements.

[0013] Furthermore, step S1 specifically includes the following steps:

[0014] S11: Defines the layers of the electrical vector diagram of the box-type substation. The order from the bottom layer to the top layer is the static object layer, the line layer, the monitoring object layer, and the switchgear layer. The layers other than the static object layer are called dynamic object layers.

[0015] S12: The static object layer includes the primary system wiring diagram of the prefabricated substation; the line layer includes line elements; the monitoring object layer includes monitoring object elements such as current, voltage, temperature, power, and frequency; and the switchgear layer includes electrical elements with opening / closing attributes such as circuit breakers, disconnectors, and grounding switches. Elements with electrical equipment attributes in the electrical vector diagram are called electrical elements, and all elements can be called visualization elements.

[0016] S13: Attributes required for visual element editing. Element attributes include element ID, coordinates, animation, layer, group, and related elements.

[0017] S14: Establish the binding relationship between the monitored object graphic elements and the monitoring data address, traverse the visual graphic elements, bind the binding relationship and the modified information to the corresponding visual graphic elements, and then construct the visual information table from the visual graphic elements.

[0018] Furthermore, step S2 specifically includes the following steps:

[0019] S21: Traverse the visualization information table, save the changed image data as an information object, and store the information object in the shared data set G; traverse the monitoring object layer, find the corresponding information object in the shared data set G by the ID of the monitoring object element in the layer, replace the ID of the monitoring object element with the address of the monitoring data, and modify the other visual elements in the electrical vector diagram whose information has been changed.

[0020] S22: Extract the monitoring object primitive information from the shared data set G, and save the corresponding monitoring data address to the address set J.

[0021] Furthermore, in step S21, the monitoring object element ID is replaced, and a row of data in the visualization information table is stored as an object j. i Where i = 0, 1, 2, 3, ...; The corresponding object j is found based on the ID of the monitored object element in the electrical vector diagram. i Replace the ID of the monitored object's graphic element with j i The address of the monitoring data; create an address set J, and put the found j i The address is stored in address set J.

[0022] Furthermore, in step S3, the association relationship of the visualized graphic elements is established, specifically including: there are one or more switch equipment graphic elements on the line graphic element, and a many-to-one association relationship is established between the switch equipment graphic element and the line graphic element; one or more monitoring object graphic element IDs can be added to the relevant graphic element attributes of the line graphic element to establish a one-to-many association relationship between the line graphic element and the monitoring object graphic element; there is also an association between the total line graphic element and the branch line graphic element in the electrical transmission relationship, and a one-to-many association relationship is established between the total line graphic element and the branch line graphic element.

[0023] Step S3 specifically includes the following steps:

[0024] S31: First, group the visual elements and process the visual elements within a group;

[0025] S32: The top left corner of the electrical vector diagram is the origin of the coordinate system. Line elements with inflection points are copied to generate new line elements. The new line elements are segmented according to the inflection points, and the segmented line elements are divided into vertical and horizontal line elements. Line elements without inflection points are directly divided into vertical or horizontal line elements.

[0026] S33: Determine the correlation between switchgear elements and circuit elements;

[0027] 1) For vertical route elements, the following two conditions should be met:

[0028] a. The midpoint of the upper and lower boundaries of the switchgear element is located between the midpoints of the endpoints of the line element;

[0029]

[0030] b. The horizontal coordinate of the circuit diagram element is located between the horizontal coordinates of the left and right boundaries of the switch equipment diagram element;

[0031] x[SW gm ]l <x[CUR gm ]<x[SW gm ] r

[0032] 2) For horizontal lines, the following two conditions must be met:

[0033] a. The horizontal coordinate of the midpoint of the upper and lower boundaries of the switchgear element is located between the two horizontal coordinates of the circuit element;

[0034]

[0035] b. The vertical coordinate of the circuit diagram element is located between the vertical coordinates of the left and right boundaries of the switchgear diagram element;

[0036] y[SW gm ] r <y[CUR gm ]<y[SW gm ] l

[0037] Where x and y represent the horizontal and vertical coordinates of the electrical element, respectively; the upper, lower, left, and right boundaries of the element are represented by u, d, l, and r; CUR represents the circuit element, and SW represents the switchgear element; gm represents the element with group g and sequence number m, where m = 0, 1, 2, 3, 4, 5…., 0 represents the element on the main line in the group, and 1, 2, 3, 4, 5…. represents the element on the branch line in the group; for example, y[CUR gm ] d This represents the ordinate of the line element with serial number m in group g.

[0038] 3) If a switchgear element has been associated with a segmented line element, then associate the switchgear element with the line element before segmentation.

[0039] S34: Traverse the line elements in the line layer, and classify the line elements into line elements with non-empty related attributes and line elements with empty related attributes based on whether the related attribute of the line element is empty; for line elements with non-empty related attribute, establish an association relationship with the monitored object elements using the related attribute of the line element; for line elements with empty related attribute, construct a one-to-many association relationship between line elements and monitored object elements using the electrical transmission relationship that the input current and output current of the line node are equal.

[0040] Furthermore, in step S4, data visualization is implemented, with three states: offline, online abnormal, and online normal. These three states are quickly expressed by switching visualization layers. It is determined whether the data of the box-type substation is online. If it is not online, all layers are hidden. If it is online but there is no data push, the static object layer is displayed and the dynamic object layer is closed. If it is online and there is data push, both the static and dynamic object layers are displayed. Then, the monitoring data is parsed according to the address set J and pushed to the monitoring object elements with the corresponding IDs. According to the association relationship of the elements, the associated switchgear elements and line elements change according to their animation and other attributes.

[0041] The beneficial effects of this invention are as follows: This method standardizes the layers and visual elements within the layers of the electrical vector diagram in a prefabricated substation, laying the foundation for subsequent batch operations on these visual elements. Simultaneously, by introducing a visualization information table, it records the binding relationship between monitored object elements and monitoring data, as well as information on visual elements that need modification. Before visualization interaction, the changed information in the visualization information table is synchronized to the electrical vector diagram; this allows the visual elements in the electrical vector diagram to establish relationships between elements based on their attributes and electrical transmission relationships, reducing the difficulty of establishing these relationships; and the binding relationship between visual elements and monitoring data, along with the relationships between visual elements themselves, improves the interaction speed when monitoring data interacts with visual elements. This invention reduces the development difficulty of visualizing monitoring data in prefabricated substations and improves the level of digitization in prefabricated substations.
