Description

Technical Field

[0001] The present invention relates to the technical field of substations, and particularly to a method and device for extracting and managing inspection points of a substation, and a computer program product. Background Art

[0002] With the continuous advancement of power grid operation modes such as intelligent substations, unattended substations, and centralized monitoring of substation operation, the auxiliary monitoring device of the substation, as one of the important technical means necessary for power grid intelligence and safe production, provides an important guarantee for the safe and stable operation of the power grid.

[0003] Currently, for the management of inspection points in substations, the orientation of the camera is remotely adjusted on-site, and according to the relationship between the picture and the inspection position, the heading angle, pitch angle, and magnification of the camera are obtained and stored and managed as the pre-set positions of the equipment inspection points. The stored data is the inspection pre-set positions, including data on the inspected equipment, inspection cameras, the heading angle and pitch angle of the inspection cameras, and the magnification; the inspection pre-set positions lack GIS three-dimensional space coordinates of the inspection points, the normal orientation of the inspection points, the inspectable included angle of the inspection points, inspection categories, inspection weights, etc. Such inspection pre-set positions have the following problems:

[0004] When the substation has been in operation for a certain period of time during operation, the components of the camera equipment gradually become weak, and the actual operating angle of the equipment has an error value compared with the theoretical angle, resulting in the inspection not being able to be completed according to the real set angle, and it is necessary to manually operate the camera on-site to re-adjust all the pre-set positions, with a very large workload;

[0005] The original camera pre-set positions were set on-site based on the inspection relationship between the already deployed cameras and the equipment. In this way, the on-site camera layout was carried out using work experience, and it was impossible to use algorithms to complete the camera layout design with maximum economy and maximum effect. The camera layout design required repeated on-site sampling and planning in and out of the substation, resulting in a long camera layout and construction period. Due to reasons such as the tallness of substation equipment, the existing camera layout and substation safety risk assessment are both manually estimated, and it is impossible to perform fine and reliable verification of the safety distance. When the substation experiences meteorological disasters such as strong winds, hailstorms, large-scale rain and snow, when the substation inspection cameras are updated and installed, using the existing camera inspection pre-set management method, it is necessary to re-obtain the values of all the inspection pre-set positions on-site, with a very large workload.

[0006] Therefore, the existing camera pre-set positions cannot be applied to application scenarios such as camera equipment update and modification of camera maintenance parameters, resulting in changes to the camera, and the pre-set positions need to be re-set and extracted, causing problems such as large management difficulty, large resource investment, and inability to use the device to verify the data accuracy.

[0033] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required in the embodiment descriptions. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0034] Figure 1 It is a flowchart of a substation inspection point extraction and management method in an embodiment of the present invention.

[0035] Figure 2 It is a structural diagram of a substation inspection point extraction and management device in another embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The detailed description of the drawings is intended to be an illustration of the current embodiments of the present invention, rather than representing the only form in which the present invention can be implemented. It should be understood that the same or equivalent functions can be completed by different embodiments intended to be included within the spirit and scope of the present invention.

[0037] Refer to Figure 1 , an embodiment of the present invention provides a substation inspection point extraction and management method, including the following steps:

[0038] Step S10, initialize the three-dimensional digital twin scene of the substation, and load the substation equipment and ledger information and the three-dimensional model of the inspection points;

[0039] Specifically, a three-dimensional digital model corresponding to the actual substation is created, namely, the digital twin scenario. This scenario is a virtual replica that includes all the equipment and structures of the substation; meanwhile, the equipment ledger information of the substation (including equipment type, location, status, etc.) and the three-dimensional models of the inspection points are loaded into this digital twin scenario, so that operators can set and manage the inspection points in a virtual environment.

[0040] Step S20: In response to the user's operation of placing the three-dimensional model of the inspection point, automatically obtain the normal plane of the three-dimensional model of the inspection point, and set the normal plane as the orientation normal direction of the inspection point;

[0041] Specifically, the user can adjust the position of the inspection point model in the three-dimensional digital twin scenario, and the execution device of the method will automatically identify and obtain the normal plane of the inspection point model. This normal plane represents the orientation of the inspection point, and setting this normal plane as the orientation normal direction of the inspection point ensures that the inspection camera can monitor in the correct direction.

[0042] Step S30: Obtain the user's setting or modification of the inspection point type and inspection point weight of the three-dimensional model of the inspection point;

[0043] Specifically, the user can classify the inspection points according to needs, such as key equipment, general equipment, etc., and set different inspection weights to indicate the monitoring importance of each inspection point. The execution device of the method will record the user's setting or modification of these parameters for application in subsequent inspection management.

[0044] Step S40: Adjust the three-dimensional space parameters of the inspection point according to the placed three-dimensional model of the inspection point and the set or modified inspection point data;

[0045] Specifically, the execution device of the method will adjust the three-dimensional space parameters of the inspection point, including coordinate position, orientation angle, etc., according to the position of the inspection point model placed by the user and the data such as the inspection point type and weight set by the user, so as to ensure that the spatial position and attributes of the inspection point match the actual monitoring requirements.

[0046] Step S50: Store the orientation normal direction, inspection point type, inspection point weight, and three-dimensional space parameters;

[0047] Specifically, the execution device of the method stores all the key information of the inspection points, including the normal direction of orientation, the type of inspection points, the weight of inspection points, and three-dimensional space parameters, etc., into the database. These stored data will be used to guide the actual layout of inspection cameras and inspection work, ensuring the safe and stable operation of the substation. In this way, it is convenient to query, update, and manage data, greatly improving the efficiency and accuracy of inspection point management.

[0048] In summary, the method of this embodiment realizes the accurate extraction and management of inspection points by initializing the three-dimensional digital twin scene of the substation, effectively avoiding the problem of inspection angle deviation caused by factors such as equipment aging and installation errors in the traditional pre-set position method. At the same time, by automatically obtaining the normal plane of the inspection points and the user-defined type and weight of the inspection points, the flexibility and accuracy of the inspection point setting are improved, and the optimization of the camera layout is realized. In addition, this method reduces the workload of manually adjusting the pre-set position of the camera on-site, reduces the management difficulty and resource investment, and ensures efficient application in scenarios such as camera equipment update or maintenance parameter modification, thus improving the safety and reliability of the execution device of the substation monitoring method.

[0049] In some embodiments, the type of inspection points is classified according to the different characteristics of the equipment and areas to be inspected in the substation, including at least one of equipment status inspection points, instrument reading points, temperature monitoring points, safety protection inspection points, insulator inspection points, and grounding device inspection points.

[0050] Specifically, during the inspection process of the substation, different equipment and areas have different inspection requirements and safety requirements. Therefore, the type of inspection points is classified according to the different characteristics of the equipment and areas to be inspected in the substation.

[0051] The following are the explanatory notes for each type of inspection point:

[0052] Equipment status inspection points: These types of inspection points mainly target the main equipment in the substation, such as transformers, circuit breakers, disconnectors, etc., and are used to check whether the appearance of the equipment is damaged, whether the components are loose, and whether the operating status is normal, etc.

[0053] Instrument reading points: These points are specifically used to read the readings of various instruments, such as voltmeters, ammeters, wattmeters, etc., to ensure that the electrical parameters are within the normal range and to detect and handle abnormal situations in a timely manner.

[0054] Temperature monitoring points: During the operation of the substation, equipment may generate heat due to the passage of current. Temperature monitoring points are used to monitor the temperature of key parts of the equipment (such as joints, contacts, transformer windings, etc.) to prevent equipment damage caused by overheating.

[0055] Safety protection checkpoints: These points focus on the safety protection facilities of the substation, such as fences, warning signs, fire-fighting equipment, etc., to ensure that these safety protection measures are in good condition and can effectively prevent safety accidents.

[0056] Insulator checkpoints: Insulators are important insulating components in the substation. The checkpoints are used to regularly check whether the insulators have cracks, dirt, damage, etc., to prevent electrical failures caused by insulator failure.

[0057] Earthing device checkpoints: The earthing device is crucial for ensuring the safety of the substation. These checkpoints are used to check whether the connections of the earthing device are firm and whether the earthing resistance is within the specified range, to ensure that fault current can be effectively introduced into the ground in case of a fault.

[0058] By classifying these inspection points according to different inspection requirements, the work of inspectors can be more effectively guided, ensuring that every important equipment and area can receive appropriate attention and inspection. Such classification also helps to conduct targeted data recording and analysis in the execution device of the inspection management method, improving the efficiency and accuracy of the inspection work.

[0059] In some embodiments, the weight of the inspection point refers to different weight values assigned according to the importance, fault risk, and maintenance difficulty of the substation equipment or area; the weight of the inspection point for key equipment or areas that may cause significant impact or loss in case of a fault is set to a high weight; for sub-critical equipment or areas, where the fault impact is relatively small but still requires regular inspection, the weight of the inspection point is set to a medium weight; for general equipment or areas, where the fault impact is small, the weight of the inspection point is set to a low weight.

[0060] Specifically, the setting of the weight of the inspection point is to distinguish the priorities and attention levels of different equipment and areas in the inspection management of the substation. The following is a detailed explanation of the weight of the inspection point:

[0061] High weight: High-weight inspection points are usually assigned to key equipment or areas that may have a significant impact on the operation of the substation or cause losses in case of a fault; these equipment and areas may be the core parts of the substation, such as main transformers, high-voltage circuit breakers, busbars, control and protection devices, etc.; since the failure of these equipment or areas may lead to the paralysis of the entire substation or even the power grid, they need to be inspected most frequently and strictly; the setting of high weight ensures that inspectors will give priority attention to these key points and give priority consideration in resource allocation and emergency plans;

[0062] Medium weight: Medium-weight inspection points are applicable to those devices or areas that, although not the most critical, are still important; failures in these devices or areas may not immediately paralyze the execution device of the entire method, but will still have a certain impact on the stable operation of the substation, or may lead to the loss of local functions; for example, auxiliary transformers, low-voltage distribution devices, and some secondary switchgear may be given medium weights; these points need to be inspected regularly, but compared with high-weight points, the inspection frequency and strictness can be appropriately reduced;

[0063] Low weight: Low-weight inspection points generally refer to those devices or areas with less impact on failures; these devices or areas may include some auxiliary facilities, non-critical building structures, environmental monitoring points, etc.; although failures in these points will not have a serious impact on the operation of the substation, they still need to be inspected regularly to maintain overall safety and environmental standards; the setting of low weight means that the inspection of these points can be relatively less, but they cannot be completely ignored;

[0064] By setting weights for different inspection points, the operation and maintenance management of the substation can be made more refined, which helps inspection personnel allocate inspection resources and work priorities according to the weights, thereby improving inspection efficiency and ensuring the safe and stable operation of the substation; at the same time, the execution device of this weight method also helps to prioritize the normal operation of the most important devices and areas in the case of limited resources.

[0065] In some embodiments, the three-dimensional space parameters include the optimal inspection distance range and inspection angle range of the camera, and the inspection angle range includes the horizontal angle range and the vertical angle range.

[0066] Specifically, in the embodiment, the three-dimensional space parameters are set to ensure that the camera can monitor the inspection points in the substation in the best way;

[0067] The optimal inspection distance range of the camera defines the ideal distance range between the camera and the device or area to be monitored. The optimal distance range ensures that the camera can clearly capture the details of the target object, while avoiding a narrow field of view due to too close a distance or blurred images due to too far a distance. This range can be determined according to the resolution of the camera, the focal length of the lens, the light conditions, and the specific characteristics of the object to be monitored.

[0068] The horizontal angle range refers to the viewing angle range that the camera can cover in the horizontal direction. This parameter ensures that the camera can capture the entire picture or key parts of the inspection point, and important monitoring information will not be missed due to angle limitations; for example, for a device that needs to be comprehensively monitored, the horizontal angle range of the camera should be wide enough to cover the entire side of the device.

[0069] The vertical angle range refers to the viewing angle range that the camera can cover in the vertical direction. This parameter is equally important as it ensures that the camera can observe the inspection points from different heights, including the top, bottom, and middle parts of the equipment. For some equipment that requires up-and-down inspection, such as insulators, the setting of the vertical angle range is particularly crucial.

[0070] By setting these three-dimensional space parameters, precise control of the camera layout can be achieved, ensuring that each inspection point can be effectively monitored.

[0071] Refer to Figure 2 , Another embodiment of the present invention further provides a substation inspection point extraction and management device, including:

[0076] A point data storage module 5 for storing the normal direction of the orientation, inspection point type, inspection point weight, and three-dimensional space parameters.

[0077] In some embodiments, the inspection point type is classified according to the different characteristics of the equipment and areas to be inspected in the substation, including at least one of equipment status inspection points, instrument reading points, temperature monitoring points, safety protection inspection points, insulator inspection points, and grounding device inspection points.

[0078] In some embodiments, the inspection point weight refers to different weight values assigned according to the importance, failure risk, and maintenance difficulty of the substation equipment or area; the weight of the inspection point of key equipment or areas that may cause significant impact or loss in the event of a failure is set to a high weight; for the inspection points of sub-critical equipment or areas where the failure impact is relatively small but still requires regular inspection, the weight is set to a medium weight; for the inspection points of general equipment or areas with a small failure impact, the weight is set to a low weight.

[0079] In some embodiments, the three-dimensional space parameters include the optimal distance range and the inspection angle range of the camera, and the inspection angle range includes a horizontal angle range and a vertical angle range.
