[0017] The present invention generates a monitoring page corresponding to the graphic template by instantiating the generated graphic template, specifically by decomposing the elements in the station model into static elements and dynamic elements; copying the static elements in a blank template and binding the dynamic elements to generate the graphic template, thereby generating the corresponding monitoring page, reducing the graphic generation cycle, solving the problems of time-consuming, error-prone, irregular graphics and inconsistent display effects in manual drawing of power grid graphics, and making the drawn power grid graphics closer to the actual situation.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] Example of a method for automatically generating a monitoring page for a centralized control station based on a template: In view of the characteristics of a large number of substations connected to the centralized control station system, a wide monitoring range, and a large amount of access information, a single substation monitoring page has hundreds of pages. In order to quickly create monitoring pages, this embodiment designs a template-based centralized control station monitoring page automatic generation method, such as Figure 1 As shown, the specific steps are as follows: (1) Make model templates, interval wiring diagram templates and graphic templates.

[0020] Model template: Model template is a template system created for substation electrical model. First, it is classified in detail according to the type of electrical equipment. For different substation types, substation interval types, electrical equipment types, and measuring point types, a template system that meets all existing substation types is created. It is equivalent to the big data of substation model, covering and supporting various model requirements of substation. The models here are all for types, not the actual substation model. This template is used to make interval wiring diagram templates.

[0021] Bay wiring diagram template: The bay wiring diagram template is generated based on the actual bay diagram in the substation. The style of the substation bay wiring diagram is summarized and summarized, separated from the actual model, and the style features are extracted to construct a style template library. The template saves the type information of the electrical equipment, and associates the graphic information of the bay wiring diagram template with the actual equipment type through the model information of the model template. It not only has shape information, but also includes the equipment type information in the bay and the topological connection relationship between the equipment. It can also be said that the bay wiring diagram template is equivalent to the style big data of the bay wiring diagram. Figure 3 shown.

[0022] Graphic template: Graphic template summarizes the corresponding page types for hundreds of monitoring pages of substations, and makes a template for each type. Graphic template is used for instantiation to generate monitoring pages; Graphic template includes at least one of hundreds of page types required for main and auxiliary monitoring such as substation main wiring diagram, interval sub-diagram, plant wiring diagram, light-sign index diagram, secondary network structure, event list, AC / DC system fault recording diagram, fire monitoring homepage, fire alarm, etc., and contains all elements in the page, namely dynamic elements and static elements. For example, page background, page title, wiring diagram area, measurement data, light-sign information, hyperlink jump and other elements. The specific steps of generating graphic template are as follows: first, decompose the elements in the diagram into dynamic elements and static elements according to the characteristics of the diagram to be generated; copy static elements in the blank template and bind dynamic elements to generate graphic template, where dynamic elements refer to graphic elements related to the power model extracted from the same type of monitoring page, and static elements refer to graphic elements unrelated to the power model, that is, graphic elements that will not change in different pages due to different bound models; the power model is the modeling and analysis of the entire power system. The power model integrates multiple electrical models. For each electrical device in the power system (such as generators, transformers, transmission lines, etc.), corresponding electrical models need to be established to simulate their operating characteristics and behaviors, thereby forming a comprehensive simulation and analysis of the entire power system. This integration helps to fully understand the operating status and performance of the power system, so as to formulate more effective operation and planning strategies. Electrical model: usually refers to the modeling of specific parts of the electrical system (such as circuits, motors, transformers, etc.), focusing on the relationship and changes between electrical parameters (such as voltage, current, resistance, inductance, etc.). The site model is an important part of the power model. Site model: usually refers to the specific modeling of power facilities such as power plants and substations. These models describe in detail the equipment layout, operating conditions, energy conversion process, etc. in the site. In the power model, sites such as power plants and substations are key nodes for power production and distribution, and detailed site models need to be established to simulate their operating status and performance. It also includes a layout container, which is used to fix the area position of the blank template and replace the graphic information. The layout container is essentially composed of a rectangular area, which can be configured with relevant attributes. By parsing the attribute information, it is automatically replaced with the corresponding graphic information, and the graphics in the layout container are automatically arranged according to the configured layout method. Figure 2 As shown in the figure, the red rectangular boxes are various layout containers.

[0023] (2) Automatically generate graphics for the entire site.

[0024] Select the dynamic elements required by the model in the station and bind them to the blank template after copying the static elements. The dynamic element binding methods include at least one of direct association, algorithm association, layout association and conditional association; among them, direct association is to bind variables; algorithm association is to bind the jump path relationship between the configured page and the graphic template obtained by the algorithm; layout association is to obtain the template in the interval wiring diagram template that is closest to the topological relationship of the station model interval equipment, calculate the interval position through the spatial layout algorithm according to the interval wiring diagram template, and adjust the interval position according to the calculation result of the interval position before binding; conditional association is to bind the displayed conditions.

[0025] The process of obtaining the jump path relationship between the configured page and the graphic template through the algorithm includes: obtaining the model information of the graphic template and the dynamic hyperlink attribute of the configured page, judging whether the model of the configured page and the graphic template is related, and if not, directly generating the jump path based on the basic path; if relevant, calculating the model association relationship, and generating a dynamic model path related to the model based on the model association relationship. Figure 6 shown.

[0026] The specific process of adjusting the interval position is: divide the interval spacing equally by obtaining the busbar position and length in the basic graphic layout; judge whether there is overlap between the intervals: if there is no overlap after dividing the interval spacing equally, it is the final interval position; if there is overlap after dividing the interval spacing equally, adjust the number of intervals on both sides of the busbar and divide the interval spacing equally again until there is no overlap between the intervals. Figure 7 shown.

[0027] Among them, the data bound by direct association includes page name and four remote control data; the data bound by algorithm association includes jump path; the data bound by layout association includes wiring diagram; the data bound by conditional association includes light-emitting signboard. For example, when the bound data is light-emitting signboard, the corresponding display condition is the grid container condition for displaying the light-emitting signboard position in the graphic template.

[0028] The actual implementation method of the automatic generation method of the centralized control station monitoring page based on the template is as follows: Take A centralized control station as an example: In the construction of A centralized control station, the actual model of the substation is modeled according to the model provided by the centralized control center. After the modeling is completed, the monitoring page is drawn. According to the monitoring page layout requirements of A, a set of graphic templates are made, including main wiring diagram, interval sub-diagram, protection light sign diagram, interval light sign diagram and dozens of other graphic templates. The following takes the main wiring diagram and interval diagram as examples.

[0029] ① The main wiring diagram mainly displays the connection status of the electrical equipment of the whole station, the status of the electrical equipment, and some important electrical measurement values. When making the main wiring diagram template, according to the characteristics of the main wiring diagram, the elements of the main wiring diagram are decomposed into background elements, page title elements, hyperlink jump elements, wiring diagram elements, and some important electrical measurement elements. According to the layout requirements, the high-voltage side, medium-voltage side, low-voltage side, and main transformer of the main wiring diagram are divided into four areas, and the layout container is used to fix the positions of the four areas. The page title dynamically binds the substation name variable in the variable system (such as A centralized control station ${stationname}$ main wiring diagram). The hyperlink jump element only needs to be configured to bind the page type to jump, such as the plant station directory, light-emitting sign index diagram, AC / DC system diagram, and the electrical measurement value is bound by the type condition of the electrical quantity (such as meatypeid =31).

[0030] ② The interval sub-diagram mainly displays the electrical equipment connection status, electrical equipment status, and some important electrical measurement values ​​of this interval. When making the interval sub-diagram template, according to the characteristics of the interval sub-diagram, the elements of the interval sub-diagram are decomposed into background elements, page title elements, hyperlink jump elements, interval wiring diagram elements, some important electrical measurement elements, protection and measurement light signs, etc. According to the layout requirements, the position of the interval wiring diagram is fixed using the layout container, and the page title is dynamically bound to the variables in the variable system (such as A centralized control station ${stationname}$${bayname}$ diagram). The hyperlink jump element only needs to be configured to bind the page type to jump, such as the plant station directory, light sign index diagram, AC and DC system diagram, and the electrical measurement value is bound through the type condition of the electrical quantity (such as meatypeid=31). The protection and measurement light signs are conditionally bound through the grid container configuration (such as meatype=304&sigalclass =1001).

[0031] After the graphic template is made, the whole station graphics are automatically generated. Take the main wiring diagram of station A and station B and the 220kV line 1 interval diagram as examples: Read the graphic template information of the main wiring diagram, and directly replace the variable information in the graphic template with the actual value, for example, ${stationname}$ is replaced with station B; the hyperlink jump element calculates the hyperlink page path according to the configured page type, and binds it to the generated main wiring diagram; the electrical measurement value searches the model for the corresponding type of electrical quantity through the configured conditions to instantiate the specific electrical quantity, thereby binding the actual measurement value (such as the configured accident total, abnormal total and other types of signals, you can go to the model library to find the point of this type, and directly bind the model after finding it). For the wiring diagram elements, first according to the model given by the centralized control center, take the model of a single interval as the unit, and match the optimal solution in the interval wiring diagram template through the topological relationship, that is, the interval wiring diagram template that best fits the current model. After all interval templates are successfully matched, the relative position of each interval can be calculated according to the layout container and spatial layout algorithm in the main wiring diagram, and dynamically adjusted to prevent overlapping and crossing related problems. After adjustment, the relative position of the adjusted interval is bound, because the drawing is made in intervals, which greatly avoids the overlap of electrical equipment and the occurrence of cross-connection on site. Specific graphic templates such as Figure 4 As shown, the bound graphic template is as follows Figure 5 shown.

[0032] The specific process of generating interval sub-diagrams is the same as that of the main wiring Figure 1 However, the protection and control light-sign information displayed in the interval sub-diagram cannot be fully displayed due to the large number. According to the grid container conditions configured in the graphic template, the light-sign signals that meet the conditions in the database are directly bound and displayed in the grid container according to the configured display method. At the same time, it meets the needs of folding and expanding display when there are too many light-sign signals.

[0033] Example of a device for automatically generating monitoring pages of a centralized control station based on a template: The present invention also provides a device for automatically generating a monitoring page for a centralized control station based on a template, the device comprising a memory and a processor, and a computer program stored in the memory and running on the processor, the processor being used to execute computer program instructions stored in the memory to implement a method for automatically generating a monitoring page for a centralized control station based on a template. The specific process has been described in detail in the embodiment of the method for automatically generating a monitoring page for a centralized control station based on a template, and will not be repeated here. Among them, the processor can select a processing device such as a microprocessor MCU, a programmable logic device FPGA, etc., and the memory can select a storage device such as a mobile hard disk, a read-only memory (ROM), and a random access memory (RAM).

[0034] Specific implementation methods are given above, but the present invention is not limited to the described implementation methods. The basic idea of ​​the present invention lies in the above basic scheme. For ordinary technicians in this field, it does not take creative work to design various deformed models, formulas, and parameters according to the teachings of the present invention. Changes, modifications, substitutions, and variations of the implementation methods without departing from the principles and spirit of the present invention still fall within the scope of protection of the present invention.
