[0052] With the continuous deepening of smart grid construction, substations, as the core components of the power system, have a direct impact on the stability and reliability of the power grid with their operating efficiency and intelligence level. In related technologies, the traditional substation drawing design and management methods have problems such as long manual drawing time, low efficiency, easy errors, poor flexibility, and difficulty in real-time updating. It is difficult to fully, quickly and accurately reflect the complexity, diversity, and real-time nature of substation internal drawings, and it is difficult to meet the needs of rapid response and precise management of substations.

[0053] Based on the above problems, the present invention provides a method and system for generating a main wiring diagram of a substation, aiming to realize fast, accurate and multi-style automatic generation of the main wiring diagram of the substation through automation means, thereby improving the operation and management efficiency of the substation.

[0054] Example 1

[0055] See also Figure 1 As shown, it is a schematic diagram of a flow chart of a method for generating a main wiring diagram of a substation provided by the present invention, wherein the method for generating a main wiring diagram of a substation can be combined with Figure 1 The steps shown are explained below:

[0056] Step 101: Use a machine learning algorithm to extract features from basic data of multiple devices in the substation to obtain multi-level features.

[0057] The multi-level affinity features are used to characterize the physical connection relationship, logical hierarchical relationship and functional dependency relationship between the multiple devices.

[0058] In some embodiments of the present invention, a machine learning algorithm may be used to perform data analysis and feature mining on basic data of multiple devices in a substation, thereby obtaining multi-level features. Here, feature extraction refers to data analysis and feature mining.

[0059] The multiple devices in the substation may refer to the main devices of the substation, including but not limited to: transformers, switches, circuit breakers, busbars, bay unit devices, etc. Correspondingly, the basic data of the multiple devices include but are not limited to: device locations, connection relationships, attribute information, etc.

[0060] Here, the substation is an electric power facility in the power system that transforms voltage, receives and distributes electric energy, controls the flow of electricity and adjusts voltage. It connects power grids of various voltage levels through its transformers.

[0061] It should be noted that machine learning algorithms are data- and experience-based algorithms that automatically discover patterns, rules, and associations in data by learning and analyzing large amounts of data, and use these patterns and rules to perform tasks such as prediction, classification, or optimization. The goal of machine learning algorithms is to extract useful information and knowledge from data and apply it to new unknown data.

[0062] In some embodiments of the present invention, the machine learning algorithm may be an algorithm based on statistical principles or an algorithm based on neural networks, and the present invention does not impose any limitation on this. Here, a machine learning algorithm may be used to extract features based on basic data between multiple devices in a substation, such as actual device data, electrical information of topological data, connection information, etc., to obtain multi-level affinity features; wherein, the voltage level may be used as a feature of the layout position and graphic rendering of high, medium and low voltages for feature extraction; the device type may be used as an electrical characteristic and a feature of graphic rendering for feature extraction; the topological structure between devices and connected devices, and between devices may be used as a relationship feature for feature extraction, thereby obtaining multi-level affinity features.

[0063] In some embodiments of the present invention, multi-level affinity features are used to characterize the physical connection relationship, logical hierarchical relationship and functional dependency relationship between multiple devices, that is, multi-level affinity features are used to describe the closeness between multiple devices in a substation, and this closeness can be reflected in terms of the physical connection level, logical level and functional level.

[0064] In some embodiments of the present invention, the physical connection relationship between multiple devices in a substation may refer to the actual connection characteristics between multiple devices, for example: the equipment connection structure relationship between busbars determines the wiring mode of the busbar, such as bus coupling, bridging, single bus, double bus, segmentation, bypass and other wiring modes; the equipment connection structure relationship between transformers and busbars may determine line transformer groups, internal bridges, external bridges, etc. The logical hierarchical relationship between multiple devices in a substation refers to stratifying the logical relationship of multiple devices in a substation according to the order of structural complexity, for example, transformers and busbars are regarded as first-layer devices, the connecting lines connected thereto are regarded as second-layer devices, branches and convergence devices are regarded as third-layer devices, and so on. The functional dependency relationship between multiple devices in a substation can be used to express, for example: the incoming and outgoing lines are connected to circuit breakers, and the dependency relationship of device connections is clarified according to the main functional characteristics of the equipment.

[0065] In some embodiments of the present invention, the above step 101 may be implemented by the following steps 1011 and 1012 (not shown in the figure):

[0066] Step 1011: pre-process the basic data to obtain intermediate data.

[0067] In some embodiments of the present invention, preprocessing includes, but is not limited to, data cleaning, data error correction, data format conversion and other preprocessing operations.

[0068] Step 1012: Use the machine learning algorithm to extract features from the intermediate data to obtain the multi-level affinity features.

[0069] In this way, the basic data of multiple devices in the substation, such as device location, connection relationship, attribute information, etc., are preprocessed, and then the preprocessed data is subjected to feature extraction using a machine learning algorithm to obtain multi-level affinity features. In this way, the efficiency and accuracy of obtaining multi-level affinity features can be improved.

[0070] Step 102: construct multiple in-station equipment topology models that match the multi-level affinity features.

[0071] In some embodiments of the present invention, the extracted multi-level affinity features can be comprehensively analyzed to identify key nodes, connection paths, connection density and other information corresponding to multiple devices, so as to construct multiple in-station equipment topology models corresponding to the substation with the help of this information.

[0072] In some embodiments of the present invention, various in-station equipment topology models include but are not limited to: single mother model, single mother segmented model, single mother with bypass model, single mother segmented with bypass model, dual mother model, dual mother segmented model, dual mother segmented with bypass model, line transformer group model, 3 / 2 wiring model, and bridge wiring model.

[0073] Here, each of the multiple in-station device topology models can be customized with different graphic display styles and layout designs according to the wiring method between devices.

[0074] In some embodiments of the present invention, the above step 102 may be implemented by the following steps 1021 and 1022 (not shown in the figure):

[0075] Step 1021: Analyze the multi-level affinity features to obtain key nodes, connection paths, and connection densities corresponding to the multiple devices.

[0076] In some embodiments of the present invention, the connection paths corresponding to multiple devices may refer to the main connection paths between device 1 and device 2 in multiple devices, for example: the main path from transformer to inlet and outlet as the line transformer group connection method; the path from transformer to device connection between buses; the path from bus to device connection between buses; the path from bus to inlet and outlet, etc. At the same time, the connection density corresponding to the multiple devices can determine the dense area corresponding to the multiple devices based on the connection density, and the dense devices in the dense area need to be adjusted or processed in layout.

[0077] Step 1022: construct the multiple in-station equipment topology models based on the key nodes, the connection paths, and the connection density.

[0078] In some embodiments of the present invention, a variety of different in-station equipment topology models are established based on the acquired information: key nodes, the connection paths and the connection density, so that the main wiring diagram of the substation corresponding to the subsequent output based on the variety of different in-station equipment topology models can be realized.

[0079] In this way, feature analysis and modeling are performed through multi-level affinity features. That is, based on the key nodes, connection paths and connection densities corresponding to multiple devices obtained based on feature analysis, various in-station equipment topology models are efficiently constructed, thereby providing a parameter basis for the subsequent generation of the substation main wiring diagram.

[0080] Step 103: Based on the multiple in-station equipment topology models, the multiple devices are laid out and connected to generate a main wiring diagram of the substation.

[0081] In some embodiments of the present invention, suitable layout algorithms (such as hierarchical layout, grid layout, etc.) can be used for automatic layout. At the same time, in the layout process, the mutual relationship between multiple devices in the substation (multiple in-station equipment topology models are already available) and spatial constraints can also be considered to further ensure that the generated substation main wiring diagram has a clear structure and distinct levels. In addition, according to the attributes and connection relationships of multiple devices in the substation, graphic elements such as connection lines and annotation information can be automatically drawn to form the final substation main wiring diagram.

[0082] In some embodiments of the present invention, before executing the above step 103, the following step A1 may be executed first:

[0083] Step A1: Acquire the spatial constraint relationship between the multiple devices.

[0084] In some embodiments of the present invention, the spatial constraint relationship between multiple devices includes but is not limited to: spatial distance constraints, spatial partition constraints, spatial shape constraints, and spatial pattern constraints, for example: the distance between device 1 and device 2 must be greater than a preset distance, etc.

[0085] Correspondingly, the above step 103 can be implemented by following the following step A2:

[0086] Step A2: Based on the spatial constraint relationship and the multiple in-station equipment topology models, the multiple devices are laid out and connected to generate the main wiring diagram of the substation.

[0087] In some embodiments of the present invention, the attributes and connection relationships between multiple devices can be obtained based on the spatial constraint relationships and the mutual relationships between multiple devices corresponding to multiple in-station equipment topology models, thereby realizing automatic drawing of connection lines, marking information, etc. to obtain the main connection diagram of the substation.

[0088] In this way, by making use of the spatial constraint relationship between multiple devices and various in-station equipment topology models, corresponding layout and connection can be carried out to generate a substation main wiring diagram with a clear structure and distinct levels.

[0089] In some embodiments of the present invention, after executing step 103 of "laying out and connecting the multiple devices based on the multiple in-station device topology models to generate the substation main wiring diagram", the following step B may also be executed:

[0090] In response to receiving a control operation directed to a user interaction interface, adjusting the substation main wiring diagram based on a control instruction carried by the control operation to obtain an adjusted substation main wiring diagram;

[0091] Wherein, the user interaction interface at least includes a display area for displaying the main wiring diagram of the substation.

[0092] In some embodiments of the present invention, the user interaction interface can be displayed on the relevant display module, and the user interaction interface can include not only: a display area for displaying the main wiring diagram of the substation, but also: a control menu area, etc. The user display interface can allow relevant operating users in the substation to partially modify and adjust the generated main wiring diagram of the substation to carry out expansion, monitoring and other services.

[0093] Here, the control operation for the user interaction interface includes, but is not limited to: control operations generated by related touch, control operations generated by operating an external input device (such as a mouse) of the system where the user interaction interface is located, etc.

[0094] In some embodiments of the present invention, the control operation on the user interaction interface includes, but is not limited to: local adjustment operation on the substation main wiring diagram, display brightness adjustment operation on the substation main wiring diagram, control operation of scaling the substation main wiring diagram, etc.

[0095] In this way, by combining the control operation of the user interaction interface and adjusting the main wiring diagram of the substation, the user can make partial modifications and adjustments to the automatically generated in-station diagram, thereby updating the in-station diagram in a timely manner, thereby improving the operation and management efficiency of the substation.

[0096] Refer to the above description, such as Figure 2As shown, it is a schematic diagram of the components of the device corresponding to the method for generating the main wiring diagram of a substation provided by the present invention. The device can be composed of: a data input module 201, a data preprocessing module 202, a feature extraction module 203, a feature analysis module 204, a topology modeling module 205, an automatic layout module 206, a graphics drawing module 207 and a user interaction module 208. Here, firstly, the data input module 201 can be used to collect basic data of multiple devices in the substation, so that the data preprocessing module 202 can perform preprocessing operations such as data cleaning, error correction, and format conversion on the collected basic data of multiple devices; secondly, the basic data after the preprocessing operation can be The multi-level affinity features are input into the feature extraction module 203 for extraction, so that the extracted multi-level affinity features are input into the feature analysis module 204 for feature analysis to obtain analysis results; then, the analysis results are input into the topology modeling module 205 for model construction to obtain various in-station equipment topology models, and the various in-station equipment topology models obtained are successively laid out and connected by the automatic layout module 206 and the graphics drawing module 207 to obtain the substation main wiring diagram; here, the obtained substation main wiring diagram can be further input into the user interaction module 208 to enable the relevant operation user to make relevant adjustments and modifications to the obtained substation main wiring diagram.
