Description

Technical Field

[0001] This invention relates to the field of power system automation technology, and in particular to a method and system for generating primary wiring diagrams for relay protection and control devices. Background Technology

[0002] The primary wiring diagram of a relay protection control device is used to display internal information of the device. While its appearance is based on the substation's overall primary main wiring diagram, there are significant differences in function and storage methods. Currently, the primary wiring diagram for relay protection devices is primarily drawn by developers using designated tools based on the shape of the substation's primary wiring diagram. This method is time-consuming, and due to variations in manual drawing, it cannot guarantee a high degree of consistency between the diagram displayed on the device and the original design. This issue stems from the high design difficulty of the primary wiring diagram for relay protection control devices and the substation's primary main wiring diagram... Figure 1 The problem of poor consistency is addressed by traditional methods that rely on machine learning to train models using large amounts of data to identify the types and locations of elements on the primary wiring diagram of a substation. However, this traditional approach has significant drawbacks. First, different substations may display the same elements differently due to inconsistent design styles, resulting in a lack of universality in the model parameters. Second, machine learning methods require substantial data and computing power, and the human resources required for data creation far exceed those of traditional manual drawing of primary wiring diagrams. Summary of the Invention

[0003] The purpose of this invention is to solve at least one technical problem in the background art and to provide a method and system for generating primary wiring diagrams of relay protection control devices.

[0004] To achieve the above objectives, the present invention provides a method for generating a primary wiring diagram of a relay protection control device, comprising: Based on the device bay information, extract the sub-diagram of the primary wiring diagram required for the current device from the primary wiring diagram of the substation. Image preprocessing is performed on the extracted sub-image to obtain primitive information contained in the image, including: position information, structural information and pixel value information; The obtained graphic element information and the standard graphic element information in the substation graphic element library are compared for similarity in turn. Based on the comparison results, the graphic element type of the graphic element information is determined. Based on the correspondence between the standard graphic element information in the substation graphic element library and the graphic element information required by the primary wiring diagram of the current device, a graphic element mapping table is constructed, and the graphic element file path corresponding to the graphic element information of the current device is found from the constructed graphic element mapping table; Write the location information and element type from the element information into the element file to obtain the device's primary wiring diagram.

[0005] According to one aspect of the present invention, the image preprocessing operation on the cropped sub-image to obtain primitive information contained in the image includes: position information, structural information, and pixel value information, including: Adaptive threshold binarization is applied to the extracted primary wiring diagram sub-image to generate a binary image; Perform median filtering on the binary image to remove discrete noise. Connectivity region labeling and feature map information extraction are performed on the binary image after median filtering to obtain the location information, structural information and pixel value information of each qualified connected component.

[0006] According to one aspect of the present invention, the step of sequentially comparing the obtained graphic element information with the standard graphic element information in the substation graphic element library for similarity is as follows: The graphic element information and the standard graphic element information in the substation graphic element library are compared sequentially by calculating the peak signal-to-noise ratio and structural similarity.

[0007] According to one aspect of the present invention, determining the primitive type of primitive information based on the comparison result includes: Similarity values ​​are obtained based on the calculation of peak signal-to-noise ratio and structural similarity; Select the element type of the standard element information with the highest similarity value to the current element information from the substation element library, and use it as the element type of the current element information.

[0008] According to one aspect of the present invention, it further includes: setting a minimum threshold for similarity values; when the similarity values ​​of the current device element information and all standard element information in the substation element library do not reach the minimum threshold, the current element information is determined to be a fake element, and the generation process of the device primary wiring diagram is stopped.

[0009] According to one aspect of the present invention, the step of constructing an element mapping table based on the correspondence between the standard element information in the substation element library and the element information required for the current device primary wiring diagram is as follows: The standard graphic element information used in the substation primary wiring diagram design process and the graphic element information used in the device primary wiring diagram generation process are constructed into a graphic element mapping table according to the graphic element type correspondence.

[0010] According to one aspect of the present invention, the step of writing the position information and element type from the element information into the element file to obtain the device primary wiring diagram is as follows: The element type and location information are written into the element file in a format that the device can parse, so that the element mapping table is used as the correspondence to generate the device primary wiring diagram based on the substation primary wiring diagram.

[0011] To achieve the above objectives, the present invention also provides a primary wiring diagram generation system for relay protection control devices, comprising: The device primary wiring diagram sub-diagram acquisition module extracts the required primary wiring diagram sub-diagram of the current device from the substation primary wiring diagram based on the device bay information. The primitive information acquisition module performs image preprocessing on the captured sub-image to obtain the primitive information contained in the image, including: position information, structural information and pixel value information; The element type determination module compares the obtained element information with the standard element information in the substation element library in turn for similarity, and determines the element type of the element information based on the comparison results. The element file path determination module constructs an element mapping table based on the correspondence between the standard element information in the substation element library and the element information required by the primary wiring diagram of the current device. It then searches the constructed element mapping table to find the element file path corresponding to the element information of the current device. The device primary wiring diagram acquisition module writes the location information and element type from the element information into the element file to obtain the device primary wiring diagram.

[0012] To achieve the above objectives, the present invention also provides an electronic device, including a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the relay protection control device primary wiring diagram generation method as described above.

[0014] According to the present invention, the present invention identifies the primary wiring diagram of a substation using a general image preprocessing method to obtain the position and features of the graphic elements. Based on the identified graphic elements and the data in the template library, similarity judgment is performed, thereby achieving efficient image conversion and generation with relatively low manpower and computing power costs.

[0015] This invention uses less prior data to achieve rapid one-time wiring diagram conversion and generation, which greatly reduces the computing power required for image recognition, while ensuring the fault tolerance of the recognition results.

[0016] This invention replaces the traditional method of manually drawing primary wiring diagrams, greatly improving design efficiency and standardization, and reducing the difficulty of primary wiring diagram design. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely one preferred embodiment of the invention and are only used to explain the invention. They do not limit the scope of protection of the invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0036] Example 1 Methods for generating primary wiring diagrams for relay protection control devices, including: Based on the device bay information, extract the sub-diagram of the primary wiring diagram required for the current device from the primary wiring diagram of the substation. Image preprocessing is performed on the extracted sub-image to obtain primitive information contained in the image, including: position information, structural information and pixel value information; The obtained graphic element information and the standard graphic element information in the substation graphic element library are compared for similarity in turn. Based on the comparison results, the graphic element type of the graphic element information is determined. Based on the correspondence between the standard graphic element information in the substation graphic element library and the graphic element information required by the primary wiring diagram of the current device, a graphic element mapping table is constructed, and the graphic element file path corresponding to the graphic element information of the current device is found from the constructed graphic element mapping table; Write the location information and element type from the element information into the element file to obtain the device's primary wiring diagram.

[0037] In this embodiment, the sub-diagram of the primary wiring diagram required by the current device is extracted from the primary wiring diagram of the substation based on the device interval information. That is, based on the substation interval to which the current device belongs, the sub-diagram information required by the current device is extracted from the primary wiring diagram of the entire substation, which serves as the basis for drawing the primary wiring diagram of the device and provides a data source for subsequent image preprocessing.

[0038] Image preprocessing involves taking the extracted sub-image of the substation's primary wiring diagram as input, performing adaptive threshold binarization segmentation on the input image to generate a binary image; then performing median filtering to remove discrete noise; finally, performing connected component labeling and feature map information extraction to obtain the primitive information corresponding to each qualified connected component, including: location information, structural information, and pixel value information.

[0039] In this embodiment, adaptive threshold binarization segmentation involves dividing the image to be processed into sub-blocks of a specified size and calculating the image mean for each sub-block. and standard deviation Based on this, the binarization segmentation threshold is calculated. This allows for the use of different thresholds for each region in the image, achieving higher precision segmentation.

[0040] Median filtering for noise reduction addresses the issue that isolated points often appear in the original binary image during design and printing. Some larger isolated points are marked as primitives during connected component labeling, significantly impacting program complexity. Therefore, median filtering is used after binarization to remove these isolated points, leaving only the primitive components in the image.

[0041] Connected component labeling: After binarization, the effective information in the entire image is labeled. The primitives are extracted one by one by the connected component labeling method, so as to perform subsequent operations.

[0042] Feature map information extraction and connected region labeling: Each primitive and its adjacent regions are selected by bounding box. Then, the coordinate value of the upper left corner of the primitive is extracted as the position of the current primitive. Edge information and pixel value information are extracted as the graphic features of the current primitive for subsequent feature matching.

[0043] In this embodiment, similarity comparison is performed by constructing a final evaluation index system using Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity (SSIM), both commonly used in image processing. PSNR assesses image quality by measuring the error between the reconstructed image (source information) and the reference image (standard primitives). SSIM primarily evaluates the perceptual similarity of images, focusing particularly on the similarity of brightness, contrast, and structural information. Combining these two metrics yields a more accurate similarity discrimination formula. .

[0044] In this embodiment, the primitive type is determined by comparing the primitive information corresponding to the extracted connected components with the standard primitive information in the substation primitive library using a similarity discrimination framework. A similarity value is obtained by calculating the peak signal-to-noise ratio and structural similarity. The primitive type with the highest similarity value to the current primitive information is selected from the library as the type identification result for the current primitive. Simultaneously, a minimum threshold is set. If the similarity between the current primitive and all primitives in the library does not reach the minimum threshold, the current primitive is determined to be a false primitive, and no further operations are performed.

[0045] In this embodiment, the element mapping table is constructed by creating a mapping table between the standard element information used in the substation primary wiring diagram design process and the element information used in the device primary wiring diagram drawing process. This mapping relationship resolves the issue of non-standard elements caused by inconsistencies in element design specifications between two different fields. For drawings provided by different design firms, only the mapping table needs to be modified to extend the method, without requiring a complete overhaul of the model and method, greatly enhancing the versatility of this approach.

[0046] In this embodiment, the device generates a wiring diagram in one step. After determining the specific category of the current graphic element based on its type, it finds the corresponding graphic element file path in the graphic element mapping table. Combining this with the position information of the current graphic element obtained from image preprocessing, it sequentially writes the graphic element type, graphic element position (position information), and adjacent rectangle information (i.e., the width and height of the adjacent rectangle of the graphic element; for example, width = X-coordinate of the rightmost point of the graphic element - X-coordinate of the leftmost point of the graphic element; height = Y-coordinate of the bottommost point of the graphic element - Y-coordinate of the topmost point of the graphic element) into a file in a format that the device can parse. Figure 2 As shown, this method enables the automatic generation and conversion of substation primary wiring diagrams to device primary wiring diagrams, using a mapping table of graphic elements as the correspondence.
