[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] The substation equipment status display method based on the digital twin substation provided in the embodiment of the present application can be applied to computer devices such as terminals and servers. Among them, the terminal is but not limited to various personal computers, laptops, smart phones, tablet computers and portable wearable devices, and the portable wearable device can be a head-mounted device, etc. The server can be implemented as an independent server or a server cluster composed of multiple servers.

[0033] In one embodiment, Figure 1 As shown, a method for displaying substation equipment status based on a digital twin substation is provided, and the method may include the following steps:

[0034] Step S101, obtaining a monitoring image obtained by monitoring substation equipment in a substation;

[0035] In this step, real-time video monitoring of the substation equipment in the substation can be performed to obtain monitoring images.

[0036] In some embodiments, such as Figure 2 As shown, step S101 may specifically include:

[0037] Step S201, acquiring an image obtained by monitoring a substation device in a substation as an original image;

[0038] Step S202, graying the original image to obtain a grayscale image;

[0039] Step S203, performing image enhancement and image filtering processing on the grayscale image to obtain a monitoring image.

[0040] This embodiment mainly performs preprocessing on the images obtained by monitoring to obtain a monitoring image. Specifically, in step S201, a color image obtained by monitoring the substation equipment in the substation can be obtained as an original image. Since the color image occupies a large amount of storage space and affects the execution speed, the original image can be grayed in step S202 and converted into a gray image. After the grayscale transformation, the dynamic range of the image pixels is increased, the contrast of the image is expanded, and the image is clearer and easier to identify. On this basis, in step S203, the gray image is enhanced and filtered to obtain a monitoring image. Specifically, for image enhancement processing, the image pixels can be normalized by using the mat2gray function, that is, the pixel value range is changed from [0,255] to [0,1]. By drawing the image grayscale histogram, the pixel grayscale of the desired target is stretched. The grayscale value histogram is used to enhance the image through piecewise linear transformation, in order to improve the image contrast clarity and brightness uniformity. For image filtering processing, the image noise is random and will drown the image features. Specifically, the adaptive median filter can be used to remove the noise. An n×n window filter Y is set and placed in the image. The image is scanned and the size of the central pixel of the window is used to determine whether it is a pixel. When the noise attributes of all pixels in the image are determined, the noise is removed to obtain a filtered image. This embodiment preprocesses the image of the surveillance video through image enhancement and image filtering, completely retains the image information, and improves the image contrast.

[0041] Step S102, identifying whether the substation equipment is in an abnormal working state according to the monitoring image;

[0042] This step uses monitoring images to intelligently analyze whether the monitored substation equipment is in an abnormal working state.

[0043] Step S103: if the substation equipment is in an abnormal working state, determining the grid area corresponding to the substation equipment in the digital twin substation;

[0044] In this step, the digital twin substation can be pre-divided into multiple grid areas, and each substation equipment in the substation can correspond to a digital twin device in the digital twin substation. The grid area where the digital twin device is located in the digital twin substation is the grid area corresponding to its corresponding substation equipment in the digital twin substation, and each grid area corresponds to a user terminal, which is mainly responsible for taking corresponding processing measures when the substation equipment corresponding to the grid area is in an abnormal working state. Specifically, when it is identified that the substation equipment is in an abnormal working state, the grid area corresponding to it in the digital twin substation can be searched and determined according to the equipment identification number corresponding to the substation equipment, or the grid area corresponding to it in the digital twin substation can be determined by image processing technology. As an example, the mean shift segmentation algorithm can be used to quickly identify the equipment area under the monitoring video and effectively locate the grid area where the equipment is located. The specific steps may include:

[0045] 1) Let Xi and Di represent the input and output of the feature space respectively, where i∈[1,n], n represents the total number of pixels of the input image I, and use the pixel coordinates and pixels of the image to initialize X j k＝0 .

[0046] 2) Calculate the weighted average position using the following iterative calculation formula:

[0047]

[0048] Where g is h r and h s The Gaussian kernel function is Perform iterative calculations until That is, the mean shift length is lower than the given threshold ε Th until.

[0049] 3) D i As a result of image filtering, let

[0050] 4) In D i In the equation, the spatial distance is less than h. s And the color distance is less than h r points, divide them into a cluster, and form a cluster set of the input image {C P} P＝1,2,...,m (m is the number of clusters), each area on the image corresponds to a corresponding cluster.

[0051] 5) Each cluster corresponds to a category label, which is used to mark the image.

[0052] 6) Set the minimum area of ​​the region to Area in advanceTH , then merge the area into the most similar neighborhood. After completing all the above processes, the segmentation result of the mean shift algorithm can be obtained. By segmenting the device outline, the grid area where the device is located is determined.

[0053] Regarding the division of the grid area, in some embodiments, before step S103, the grid area may be divided by the following steps, specifically including:

[0054] The power supply area corresponding to the digital twin substation is divided into multiple plots; based on the multiple plots and in accordance with the upper limit of the number of grids determined by the number of plots, multiple initial grid area division schemes are generated; according to the preset division target evaluation, evaluation results corresponding to each initial grid area division scheme are obtained; according to the evaluation results corresponding to each initial grid area division scheme, a target grid area division scheme is determined; and the power supply area corresponding to the digital twin substation is divided into multiple grid areas using the target grid area division scheme.

[0055] In this embodiment, the power supply area corresponding to the digital twin substation can be divided into multiple plots according to the set size and each plot can be numbered. The basic attributes of all plots, feeders, distribution transformers and interconnection lines in the power supply area can be counted, and then based on the multiple plots and according to the upper limit of the number of grids determined by the number of plots, multiple initial grid area division schemes are generated, that is, the upper limit of the number of grids (the upper limit of the number of grids) is set according to the total number of divided plots, and a certain number of initial grid area division schemes are generated based on the multiple plots and according to the upper limit of the number of grids, thereby further reducing the number of cross-grid lines as much as possible, and ensuring the current interconnection. The preset division target of the grid area is to keep the feeder lines in the same grid as much as possible, and the line distribution transformers in the same grid as much as possible. According to the preset division target, based on the basic attributes of the blocks, feeders, distribution transformers and tie lines counted above, the evaluation results corresponding to each initial grid area division scheme are evaluated, and then the target grid area division scheme can be determined according to the evaluation results. The grid area division scheme can also be further iterated and updated, and finally the best grid division scheme is found as the target grid area division scheme. After obtaining the target grid area division scheme, multiple grid areas can be divided in the power supply area corresponding to the digital twin substation. The scheme of this embodiment can reasonably divide the grid areas that are convenient for each user to manage the relevant substation equipment and handle abnormal conditions in a timely manner.

[0056] Step S104, sending information indicating that the substation equipment is in an abnormal working state to the user terminal corresponding to the grid area, and presenting the status indicator light of the grid area corresponding to the substation equipment in the digital twin substation with a prompt effect corresponding to the abnormal working state.

[0057] This step is mainly to know that the substation equipment is in an abnormal working state. On the one hand, the information indicating that the substation equipment is in an abnormal working state is sent to the user terminal corresponding to the grid area so as to promptly inform and remind them to take corresponding processing measures. On the other hand, in the digital twin substation, the status indicator light of the grid area corresponding to the substation equipment is presented with the prompt effect corresponding to the abnormal working state, so as to intuitively present the abnormal working state of the substation equipment to the relevant users.

[0058] In some embodiments, the abnormal operating state may include a test state, a maintenance state, or a fault state.

[0059] Based on this, further, in step S104, the status indicator lights of the grid area corresponding to the substation equipment in the digital twin substation are presented with prompt effects corresponding to the abnormal working state, specifically including:

[0060] When the abnormal working state is the test state, the status indicator light is presented in orange; when the abnormal working state is the maintenance state, the status indicator light is presented in yellow; when the abnormal working state is the fault state, the status indicator light is presented in red. That is, if the substation equipment is monitored to be in the test state, the status indicator light of the corresponding grid area in the digital twin substation will be orange, if the equipment is in the maintenance state, the status indicator light will be yellow; if the equipment is in the fault state, the status indicator light will be red. In addition, if the equipment is in a normal state, the status indicator light can be green.

[0061] In some embodiments, the edge of the digital twin device corresponding to the substation device in the digital twin substation is also preset with an edge marking line, and the initial identification state of the edge marking line may be transparent; the above method may also include the following steps:

[0062] If the substation equipment is in an abnormal working state, the edge marking line in the digital twin substation will be changed to the target identification state corresponding to the abnormal working state.

[0063] In this embodiment, the edge of the digital twin device corresponding to the substation equipment in the digital twin substation can be pre-processed by special boundary treatment, an edge marking line is preset at the edge, and its initial marking state is set to invisible transparent, so that it does not affect the presentation of other information in the digital twin substation in the initial state. When it is detected that the substation equipment is in an abnormal working state, the edge marking line is changed to a target marking state corresponding to the abnormal working state in the digital twin substation. For example, the transparent color can be changed to a visible color such as orange, yellow or red (corresponding to the target marking state). As for the specific color and its correspondence with the abnormal working state, it can be set according to the actual situation, or it can be set in the same way as the status indicator light of the aforementioned grid area. After the substation equipment resumes the normal working state, the edge marking line can be changed to transparent. Through the scheme of this embodiment, the abnormal working state of the substation equipment can be further intuitively presented in the digital twin substation with the help of the edge of the corresponding digital twin device.

[0064] In addition, the edge identification of the substation equipment in the monitoring image can be specially processed. Specifically, for boundary processing, the Prewitt operator can be used to use a 3×3 template to perform grayscale difference on the pixel points in the monitoring image to find the edge. The grayscale value of the pixel is mainly for the upper, lower, left and right points of the pixel. Then the grayscale difference is added, which can make the noise smoother to a certain extent, completely extract the edge of the substation equipment in the monitoring image, and set a transparent marking line for the edge of the substation equipment in the monitoring image. The actual steps can include: input monitoring image; Gaussian filter preprocessing; based on the dimension of the Prewitt operator, add templates in the directions of 45° and 135°; OTSU obtains dynamic thresholds; extracts the image edge according to the obtained threshold, and sets an invisible transparent marking line at the edge of the equipment. In this way, the effect of specializing the edge identification of the substation equipment in the monitoring image is achieved.

[0065] The above-mentioned substation equipment status display method based on the digital twin substation provided by the present application obtains the monitoring image obtained by monitoring the substation equipment in the substation, identifies whether the substation equipment is in an abnormal working state according to the monitoring image, and if the substation equipment is in an abnormal working state, determines the grid area corresponding to the substation equipment in the digital twin substation, sends the information representing that the substation equipment is in an abnormal working state to the user terminal corresponding to the grid area, and presents the status indicator light of the grid area corresponding to the substation equipment in the digital twin substation with the prompt effect corresponding to the aforementioned abnormal working state. This scheme combines digital twin and image monitoring and recognition technology. When the substation equipment is monitored to be in an abnormal working state, the information representing that the equipment is in an abnormal state is sent to the user terminal corresponding to the grid area of ​​the digital twin substation, so that the abnormal state alarm information is accurately transmitted to the corresponding user terminal in time so as to inform the user to take corresponding processing measures in time, and the status indicator light of the grid area corresponding to the equipment in the digital twin substation is presented with the prompt effect corresponding to the abnormal state in which it is located, and the abnormal state of the equipment and the area where it is located are intuitively transmitted to the user in the digital twin substation.
