[0053] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application 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 only used to explain the present application and are not used to limit the present application.

[0054] In one embodiment, as Figure 1 shown, a method for verifying the safety distance of substation equipment is provided. In this embodiment, the application of this method to a terminal is taken as an example for illustration. It can be understood that this method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is realized through the interaction between the terminal and the server. Among them, the terminal can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server can be realized by an independent server or a server cluster composed of multiple servers. In this embodiment, the method includes the following steps:

[0055] It should be noted that the verification method provided in the present application can be applied to the verification of the safety distance between any two substation equipment in a substation.

[0056] Step S110, obtain the substation equipment models corresponding to the two substation equipment to be verified; the distance between the substation equipment models is in a preset ratio to the actual distance between the corresponding two substation equipment.

[0057] Among them, the substation equipment can be understood as various component equipment in a substation. There are various types of substation equipment, such as transformer types, switch types, four small devices types, reactive power device types of equipment, and there are also other equipment and auxiliary devices, such as wave traps, insulators, high-voltage bushings, lead wires, grounding devices, secondary equipment, high-voltage DC equipment, etc. These equipment are collectively referred to as substation equipment.

[0058] Among them, the substation equipment model can be a three-dimensional model of the substation equipment.

[0059] In a specific implementation, relevant dimensional parameter information of two power transformation equipment to be verified and the actual distance between the two power transformation equipment can be obtained first. Based on the dimensional parameter information and the actual distance, power transformation equipment models of the two power transformation equipment are constructed in a three-dimensional model construction platform according to a preset ratio. And the ratio between the distance between the two constructed power transformation equipment models and the actual distance between the two power transformation equipment is the same as the ratio between the dimensional parameters of the power transformation equipment models and the actual dimensional parameters of the power transformation equipment.

[0060] Step S120: Perform a topological structure extraction process on each power transformation equipment model to obtain the topological structures corresponding to the two power transformation equipment respectively.

[0061] Among them, the topological structure enables the acquisition and processing of geometric body data without the 2D or 3D representation of the geometric body.

[0062] In a specific implementation, a topological structure extraction process can be performed on each power transformation equipment model through a topological structure application program (such as OpenCascade, the OCC platform, a geometric modeling basic software platform) to obtain the topological structures corresponding to the two power transformation equipment respectively.

[0063] Step S130: Determine the bounding box corresponding to each power transformation equipment according to the topological structure; the bounding box is a geometric body that can accommodate the power transformation equipment and is simpler than the power transformation equipment.

[0064] Among them, the bounding box is an algorithm for solving the optimal bounding space of a discrete point set. Its basic idea is to approximately replace a complex geometric object with a geometric body (called the bounding box) with a slightly larger volume and slightly simpler characteristics. Methods for determining the bounding box can include AABB, OBB, etc. Among them, the AABB bounding box is a simple hexahedron, and each side is parallel to a coordinate plane. The rectangular bounding box is not necessarily a cube, and its length, width, and height can be different from each other; while the OBB method determines the size and direction of the box according to the geometric shape of the object itself, and the box does not need to be perpendicular to the coordinate axes, so that the most suitable and most compact containing box can be selected.

[0065] In a specific implementation, for the determination of the bounding box corresponding to any power transformation equipment, a group of direction vectors of the topological structure corresponding to the power transformation equipment can be determined first, and then multiple support planes of the topological structure when each direction vector is used as the normal vector are determined respectively; the bounding box corresponding to the power transformation equipment is obtained according to each support plane.

[0066] Step S140: Verify the safety distance between the two power transformation equipment according to the bounding box.

[0067] In a specific implementation, the distance between two power transformation devices may include a horizontal distance and a vertical distance. Therefore, it is necessary to verify the horizontal distance and / or vertical distance between the two power transformation devices. More specifically, for the verification of the horizontal distance, it is necessary to determine verification points on the bounding boxes corresponding to the two power transformation devices in the horizontal direction, calculate the distance between the two verification points, and use it as the horizontal distance between the two power transformation devices. For the verification of the vertical distance, it is necessary to determine verification points on the bounding boxes corresponding to the two power transformation devices in the vertical direction, calculate the distance between the two verification points, and use it as the vertical distance between the two power transformation devices. Finally, compare the horizontal distance with the reference distance in the horizontal direction to obtain the verification result of the horizontal distance, compare the vertical distance with the reference distance in the vertical direction to obtain the verification result of the vertical distance, and use the verification results of the horizontal distance and the vertical distance as the verification result of the safety distance between the two power transformation devices.

[0068] In the above method for verifying the safety distance of power transformation devices, after obtaining the power transformation device models corresponding to the two power transformation devices to be verified, by extracting the topological structures of the power transformation device models, the topological structures corresponding to the two power transformation devices are obtained. Further, according to the topological structures, the bounding boxes of each power transformation device are determined, and the safety distance between the two power transformation devices is verified according to the bounding boxes. This method determines the bounding boxes through the topological structures, can obtain bounding boxes with higher accuracy, and is closer to the contours of the power transformation devices, so that the distance between the power transformation devices can be verified more accurately.

[0069] In an exemplary embodiment, in the above step S120, the extraction process of the topological structures of each power transformation device model to obtain the topological structures corresponding to the two power transformation devices can be implemented in the following manner: import each power transformation device model into the topological structure application program to obtain the point information of each power transformation device model; through the topological structure application program, perform model restoration processing on the point information to obtain the topological structure corresponding to each power transformation device.

[0070] Among them, the topological structure application program is an application program that can extract the topological structure of the model. For example, the topological structure application program can be OpenCascade, that is, the OCC platform, a basic geometric modeling software platform, which is an open-source kernel, provides parametric models, and provides feature extraction of geometric models.

[0071] In a specific implementation, after importing the power transformation device model into the topological structure application program, the topological structure application program reads the point information of the power transformation device model by components, and based on the obtained point information, obtains triangular faces, and assembles the triangular faces into a solid, thereby realizing the restoration of the model through the point information and obtaining the topological structure of the power transformation device model.

[0072] In this embodiment, the topological structure of the substation equipment model is extracted through the OpenCascade platform. The OpenCascade platform is more lightweight and is an open-source platform, which can obtain a bounding box with higher precision, so as to more accurately verify the distance between substation equipment.

[0073] In an exemplary embodiment, in the above step S130, according to the topological structure, the bounding box corresponding to each substation equipment is determined, including: for any substation equipment, determining a set of direction vectors of the topological structure corresponding to the substation equipment; respectively determining multiple support planes of the topological structure when each direction vector is used as the normal vector; and using the polyhedron formed by the support planes as the bounding box corresponding to the substation equipment.

[0074] In specific implementation, a set of direction vectors including multiple directions is selected. For example, if the direction vectors are in 4 directions, the formed bounding box can be a regular tetrahedron. Another example is that the set of direction vectors can include six direction vectors along the positive and negative directions of the three coordinate axes. At this time, the formed bounding box will be a hexahedron aligned with the coordinate axes. Then, multiple support planes of the topological structure corresponding to the substation equipment when each direction vector is used as the normal vector are respectively determined, and the polyhedron formed by the multiple support planes is used as the bounding box.

[0075] In this embodiment, multiple support planes of the topological structure corresponding to the substation equipment are determined through direction vectors in multiple directions to determine the bounding box corresponding to the substation equipment, so that the determined bounding box can be closer to the shape characteristics of the substation equipment itself and improve the accuracy of the determined bounding box.

[0076] In an exemplary embodiment, as Figure 2 shown, in the above step S140, according to the bounding box, the safety distance between two substation equipments is verified, which can be achieved through the following steps:

[0077] Step S210, determining the verification points on the bounding boxes corresponding to the two substation equipments respectively;

[0078] Step S220, performing an equal-proportion conversion on the distance between the verification points corresponding to the two substation equipments according to a preset ratio to obtain the actual distance between the two substation equipments;

[0079] Step S230, when the actual distance does not meet the benchmark distance requirement between the two substation equipments, marking the two substation equipments.

[0080] Further, in an exemplary embodiment, step S210 includes: when verifying the horizontal distance between two power transformation devices, determining the rightmost point on the bounding box corresponding to the left power transformation device as the verification point, and determining the leftmost point on the bounding box corresponding to the right power transformation device as the verification point; when verifying the horizontal distance between two power transformation devices, determining the lowermost point on the bounding box corresponding to the upper power transformation device as the verification point, and determining the uppermost point on the bounding box corresponding to the lower power transformation device as the verification point.

[0081] In a specific implementation, after determining the verification points on the bounding boxes corresponding to the two power transformation devices respectively, the distance between the verification points on the bounding boxes corresponding to the two power transformation devices can be further obtained. Since the distance between the verification points is in a preset proportion to the actual distance between the two power transformation devices, therefore, the distance between the verification points also needs to be converted proportionally to obtain the actual distance between the two power transformation devices. When it is detected that the actual distance does not meet the requirement of the reference distance between the two power transformation devices, that is, when the actual distance is less than the reference distance, the two power transformation devices are marked and the corresponding log is output.

[0082] For example, taking the verification of the safety distance between a building and a power line as an example, for the vertical distance, when the voltage level of the power line is below 1 kV, the reference distance (i.e., the safety distance) is 2.5 meters; when the voltage level of the power line is 1 - 10 kV, the reference distance is 3 meters; when the voltage level of the power line is 35 kV, the reference distance is 4 meters; when the voltage level of the power line is 60 - 110 kV, the reference distance is 5 meters. For the horizontal distance, when the voltage level of the power line is below 1 kV, the reference distance is 1 meter; when the voltage level of the power line is 1 - 10 kV, the reference distance is 1.5 meters; when the voltage level of the power line is 35 kV, the reference distance is 3 meters; when the voltage level of the power line is 60 - 110 kV, the reference distance is 4 meters.

[0083] In this embodiment, by determining the verification points on the bounding boxes corresponding to the two power transformation devices and verifying the safety distances between the two power transformation devices in the horizontal and vertical directions based on the distance between the verification points, the accuracy and speed of passing the safety distance verification can be improved.

[0084] In an exemplary embodiment, before step S120 performs topological structure extraction processing on each power transformation device model to obtain the topological structures corresponding to the two power transformation devices respectively, it further includes: determining the file type of the power transformation device model; when the file type of the power transformation device model is a preset type, performing topological structure extraction processing on each power transformation device model to obtain the topological structures corresponding to the two power transformation devices respectively.

[0085] In specific implementation, there are various application programs for constructing substation equipment models, including topology structure application programs (such as OpenCascade, OCC platform, a geometric modeling basic software platform) and conventional 3D model construction application programs (such as CAD, etc.). The substation equipment model constructed through the topology structure application program can directly represent the topology structure of the substation equipment, while the substation equipment model constructed through the conventional 3D model construction application program needs to be processed by the topology structure application program to obtain the topology structure. Among them, the preset type represents the file type of the model constructed through the conventional 3D model construction application program. Therefore, before performing the topology structure extraction process on each substation equipment model, the file type of the substation equipment model can be determined first. If the file type of the substation equipment model is the file type corresponding to the model constructed through the conventional 3D model construction application program, then perform the topology structure extraction process on each substation equipment model to obtain the topology structures corresponding to the two substation equipments respectively. If the file type of the substation equipment model is the file type corresponding to the substation equipment model constructed through the topology structure application program, then the substation equipment model can represent the topology structure and there is no need to perform the topology structure extraction process again.

[0086] For example, for substation equipment such as insulator strings, terminal boards, and flanges, they can be created through the interfaces provided by the OPENCASCADE platform. However, substation equipment such as arresters, transformers, and circuit breakers need to be created through conventional 3D model construction application programs, and the resulting file models can be fbx or ifc. The models created by the conventional 3D model construction application program can also be directly read through the interfaces provided by the OPENCASCADE platform. Therefore, whether it is a substation equipment model constructed through the conventional 3D model construction application program or a substation equipment model created based on the interfaces of the OPENCASCADE platform, they can all be represented by the topology structure provided by the OPENCASCADE platform.

[0087] In this embodiment, by determining the file type of the substation equipment model, when the file type is the preset type, the step of performing the topology structure extraction process on the substation equipment model is executed, and when the file type is not the preset type, the step of performing the topology structure extraction process on the substation equipment model is not required, thereby avoiding waste of processing resources.

[0088] In another exemplary embodiment, as Figure 3 shown, a method for verifying the safety distance of substation equipment is provided. In this embodiment, the method includes the following steps:

[0089] Step S310, obtain the substation equipment models corresponding to the two substation equipments to be verified and the file type of the substation equipment model;

[0090] Step S320: When the file type of the substation equipment model is the preset type, import each substation equipment model into the topology structure application program to obtain the point information of each substation equipment model;

[0091] Step S330: Through the topology structure application program, perform model restoration processing on the point information to obtain the topology structure corresponding to each substation equipment;

[0092] Step S340: According to the topology structure, determine the bounding box corresponding to each substation equipment; the bounding box is a geometric body that can accommodate the substation equipment and is simpler than the substation equipment;

[0093] Step S350: Determine the verification points on the bounding boxes corresponding to the two substation equipments respectively;

[0094] Step S360: According to the preset ratio, perform equal-ratio conversion on the distance between the verification points corresponding to the two substation equipments to obtain the actual distance between the two substation equipments;

[0095] Step S370: When the actual distance does not meet the benchmark distance requirement between the two substation equipments, mark the two substation equipments.

[0096] The substation equipment safety distance verification method provided in this embodiment, after obtaining the substation equipment models corresponding to the two substation equipments to be verified, extracts the topology structures of the two substation equipments respectively by performing topology structure extraction on the substation equipment models, further determines the bounding boxes of each substation equipment according to the topology structures, and verifies the safety distance between the two substation equipments according to the bounding boxes. This method can more accurately verify the distance between substation equipments by using the bounding box to replace the substation equipment.

Unless there is a clear description in this article, the execution of these steps has no strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages do not necessarily have to be executed at the same time, but can be executed at different times.
