Description

TECHNICAL FIELD

[0001] The present application relates to the field of three-dimensional digital design of substations and power engineering information technology, and particularly relates to a method and system for dynamic arrangement of a substation digital model based on data element driving. BACKGROUND

[0002] With the rapid development of smart grids and digital twin technology, substation engineering design is undergoing a profound transformation from two-dimensional CAD to full life cycle three-dimensional digital design. In the three-dimensional digital design of substations, the distribution device area is the most equipment-intensive, most complex connection, and largest design workload part, and the design quality and efficiency directly affect the quality and progress of the entire project. Currently, the mainstream three-dimensional digital design process of substations has the following problems: Manual and inefficient: designers need to manually drag individual equipment models, such as circuit breakers, disconnectors, and current transformers, from a model library, and manually adjust the safety clearance between equipment, the distance between equipment phases, the distance between equipment and busbars, frames, and supports, and the setback distance between equipment and roads or walls according to design regulations. This process is tedious, repetitive, time-consuming, and prone to errors due to human error, resulting in low design efficiency.

[0003] Isolation and irrelevance: equipment arrangement and conductor (such as busbars, downlead, and jumpers) connection are two separate steps. After completing equipment positioning, designers need to manually select equipment connection terminals for conductor connection. When a device position changes, the conductor connected to the device will not automatically update and must be manually adjusted, resulting in repetitive work and potential connection errors.

[0004] Lack of inheritance and integrity: distribution devices are typically composed of multiple identical or similar compartments (such as outgoing line compartments and busbar equipment compartments). Existing technologies lack management of compartments as a whole design unit. When modifying a compartment's parameters or type, other similar compartments will not change, and when adjusting the scheme, designers must manually modify each compartment repeatedly, which cannot achieve associated updates of "changing one place changes everywhere", and the cost of scheme iteration optimization is extremely high.

[0005] Poor reusability of typical schemes: although design units have accumulated a large number of typical design schemes, these schemes are mostly static and fixed three-dimensional digital model blocks. When reused, designers still need to manually adjust and reconstruct based on the specific parameters (such as voltage level, equipment size, and site conditions) of new projects, which cannot achieve rapid parameterization adaptation and automatic generation of typical schemes.

[0006] The root cause of the problem is that the prior art fails to convert design rules, device properties and spatial geometry into structured data elements that are computer-recognizable, computable and drivable, and to establish strong logical associations between the structured data elements. The present application aims to solve the above problems. SUMMARY

[0007] The primary purpose of the present application is to provide a data element-driven dynamic arrangement method and system for a digital model of a substation, to solve the problems of low design efficiency, poor correlation, lack of modification inheritance and difficulty in reusing typical schemes in the prior art.

[0008] Another purpose of the present application is to convert design specifications, device interfaces and spatial constraints into computable data by constructing a complete system of parameterized and vectorized data elements, to drive the automatic arrangement and update of a three-dimensional digital model, and to realize the automation, intelligentization and standardization of power distribution device design.

[0009] To achieve the above purpose, in a first aspect, the present application provides a data element-driven dynamic arrangement method for a digital model of a substation, comprising the following steps: S1, constructing a core data element library for driving three-dimensional arrangement of a power distribution device, the core data element library comprising: device interface elements, arrangement control elements and bay template elements; S2, establishing an associated mapping relationship between the device interface elements and the arrangement control elements, and storing in an associated relationship library; S3, obtaining global driving parameters, the global driving parameters comprising voltage levels and main wiring structures; S4, based on the global driving parameters, matching corresponding bay templates from a pre-set bay template library; the bay template library is a fixed generation of bay template elements; S5, according to the bay template and the associated relationship library, generating a three-dimensional arrangement model of a power distribution device in a given three-dimensional space by a constraint solving method; the positions of devices in the three-dimensional arrangement model are determined by parameterization driving of the device interface elements and the arrangement control elements; S6, automatically generating a conductor connection model connecting devices in the three-dimensional arrangement model in combination with the three-dimensional arrangement model and the bay template elements; S7, modifying any object in the global driving parameters or the three-dimensional arrangement model, triggering dynamic association update, and automatically updating all affected three-dimensional arrangement models and conductor connection models based on the associated mapping relationship.

[0010] Further, in step S1, the device interface element includes positioning reference points and terminal points extracted from the three-dimensional digital model of the device, and the positioning reference points and terminal points are defined as parameterized vector points carrying unique ID, type, interface direction and connection specification attributes.

[0011] Further, in step S1, the arrangement control element is generated as follows: the safety clearance in the design specification and the operation channel requirement are parameterized and vectorized to form a directional vector buffer zone constraint; the vector buffer zone constraint includes the minimum electrical distance between devices, the minimum distance between devices and the frame and support, and the retreat distance between devices and roads or walls.

[0012] Further, in step S1, the interval template element is a structured data set defining the interval unit in the power distribution device, and the structured data set includes a device composition list, a topology connection relationship, a default arrangement rule and associated driving parameters.

[0013] Further, in step S5, the pre-prepared interval template library pre-stores interval templates corresponding to voltage levels and main wiring structures.

[0014] Further, in step S5, the three-dimensional arrangement model of the power distribution device is calculated by a constraint solving method in a given three-dimensional space, which includes the following steps: S51, based on the number of intervals and the size of the site, the optimal row-column arrangement and spacing of the intervals are calculated by adaptive layout to generate an interval array; S52, for each interval instance in the interval array, the default arrangement rule in the interval template corresponding to the interval instance is called to instantiate the devices in the device list of the interval template; S53, taking the interface element of the device as the control point and the arrangement control element associated with the device as the constraint condition, the position of each device in the interval local coordinate system is calculated by a constraint solving method, and global conflict detection is performed.

[0015] The goal in step S5 is to determine the optimal positions of all power devices in a given three-dimensional space (which can also be understood as an interval area), to ensure that they fully meet the design specification (i.e. constraint condition), and to optimize space utilization and connection efficiency as much as possible. The following examples are explained in detail: 1), input data: The interval template object contains a list of devices to be arranged, a default topology connection relationship; the association relationship library provides a set of arrangement control elements associated with each device type; global parameters include the origin of the interval local coordinate system, the voltage level (used to determine the specific constraint value), and the site boundary.

[0016] 2), preprocessing: formal mathematical expression of constraints First, abstract text specifications, such as "safety clearance", are converted into mathematical constraints, each of which is expressed as an inequality or equation.

[0017] (1) Distance constraint: Distance(Geometry_A,Geometry_B) ≥ D_min.

[0018] Where Geometry_A and Geometry_B are the outer bounding cubes or precise collision bodies of Device A and B. D_min is the minimum safety distance obtained from the association library according to the device type and voltage level.

[0019] (2) Phase sequence alignment constraint: Device_A.Phase_i.terminal_position.x < Device_A.Phase_j.terminal_position.x, for horizontally arranged three-phase devices, to ensure that phase i is on the left of phase j. This constraint ensures that the terminals of three-phase devices are arranged in the correct order, facilitating conductor connection.

[0020] (3) Connection relationship constraint: Abs(Device_A.terminal_position.y - Busbar.position.y) ≤ Tolerance; This constraint forces the terminals of the device and the suspension points of the busbar to be within a certain tolerance range, creating conditions for smooth connection of conductors.

[0021] (4) Boundary constraint: IsInside(Device_A, Operating_Zone) == True && IsOutside(Device_AForbidden_Zone) == True; Ensure that the device is located in the operating channel, and does not exceed the fence or enter the lifting forbidden zone.

[0022] 3) Solution process The two-stage strategy of initial layout generation, conflict detection and iterative solution is adopted, as follows, which clearly shows the complete closed-loop process from problem initialization to final solution verification: (1) Construction of constraint satisfaction problem: According to the input, define a variable set V = {V_pos_i, V_rot_i} representing position and rotation for all devices in the current interval, and extract all relevant constraints from the association library to build a complete constraint satisfaction problem.

[0023] (2) Rule-based initial layout generation: Before starting the iterative solving, an initial guess is provided according to heuristic rules to accelerate the convergence. Rule example: IF Device_Type=="Circuit Breaker" THEN Place_Near_The_Front_Center(Device).

[0024] This stage will use the default placement rules in the interval template to quickly generate a layout that roughly conforms to engineering conventions, which will have constraint conflicts.

[0025] (3) Conflict detection and iterative solving: Detect conflicts in the layout of the previous step and optimize.

[0026] Conflict detection: Use the Separating Axis Theorem or spatial partitioning data structures such as BVH trees for collision detection, and list all pairs of devices that violate distance constraints, while checking other types of constraint violations.

[0027] After detecting conflicts, convert the conflicts into an optimization problem, aiming to minimize the degree of violation of all constraints.

[0028] The objective function is to minimize: Minimize(ΣViolation_Score(Constraint_i)), that is, to minimize the score of all violated constraints.

[0029] Solving method: If the constraints are differentiable, use Newton's method to quickly find a local optimal solution, use sequential quadratic programming algorithm to handle nonlinear constraints, when the solution space is complex and multi-peak, use genetic algorithm to find global optimal solution or approximate optimal solution.

[0030] Fine-tune the position (V_pos_i) and rotation (V_rot_i) of the device to generate a new layout with fewer conflicts.

[0031] (4) Loop iteration: Again, perform conflict detection on the new layout, where the process of step (3) is looped until a solution that satisfies all constraints is found or the maximum number of iterations is reached, and a current optimal solution is returned.

[0032] 4) Output and integration Output: The final output is the final pose of each device, that is, a transformation matrix containing [X, Y, Z, RotX, RotY, RotZ].

[0033] Three-dimensional model generation: After receiving the pose data, apply the final pose to the corresponding parameterized device model, and instantiate the precise device model at the specified position in the three-dimensional scene.

[0034] Data association: each instantiated device model still retains the association relationship with the device interface element and the arrangement control element, providing data for subsequent conductor connection and dynamic update.

[0035] Further, in the step S6, the conductor connection model generation specifically includes the following steps: S61, traverse the interval template element, and identify the device interface point pairs that need to be connected; S62, according to the voltage level, current value, spatial distance and interface type of the device interface point pair, match the optimal conductor and fitting type from the conductor rule library; S63, according to the spatial coordinates of the device interface point pair, automatically calculate the form and size of the conductor, and generate and assemble the three-dimensional digital model of the conductor and the fitting.

[0036] Further, in the step S7, the dynamic association update is incremental update, which is specifically implemented as: the modification operation generates an update event, the update event is propagated downward along the preset dynamic arrangement structure hierarchical relationship, and the affected interval, device and conductor object are recalculated and model updated.

[0037] In a second aspect, the present application provides a data element driven dynamic arrangement system of a substation digital model, which comprises a data element management module, a parameter receiving and analyzing module, an intelligent arrangement generation module, a conductor automatic connection module and a dynamic update engine. The data element management module is used to construct a core data element library for driving the three-dimensional arrangement of the power distribution device, the core data element library comprises device interface elements, arrangement control elements and interval template elements; and an association mapping relationship between the device interface elements and the arrangement control elements is established and stored in an association relationship library; The parameter receiving and analyzing module is used to obtain and analyze global driving parameters, and match corresponding interval templates from a preset interval template library; the interval template library is generated after the interval template elements are fixed; The intelligent arrangement generation module is used to calculate and generate a three-dimensional arrangement model of the power distribution device in a given three-dimensional space according to the interval template and the association relationship library through a constraint solving method, and the device positions in the three-dimensional arrangement model are determined by parameterized driving of the device interface elements and the arrangement control elements; The conductor automatic connection module is used to automatically generate a conductor connection model of each device in the three-dimensional arrangement model according to the interval template elements and the three-dimensional arrangement model; The dynamic update engine is used to respond to the modification operation, and schedule and execute the dynamic association update.

[0038] In a third aspect, the present application can also provide a computer readable storage medium, wherein a computer program is stored in the computer readable storage medium, and the computer program is executed by a processor to implement the data element driven dynamic arrangement method of the substation digital model.

[0039] Compared with the prior art, the present application has at least the following beneficial effects: Improved design efficiency: based on the global driving parameters, the corresponding interval template is matched from the pre-set interval template library; and according to the interval template and the correlation relationship library, the three-dimensional arrangement model of the power distribution device is automatically calculated and generated, so that the designer is completely liberated from repetitive manual dragging and adjusting work, the design scheme generation is shortened from the hour level to the minute level, and the efficiency is improved by more than one order of magnitude. Internal quality assurance: all arrangement parameters are automatically calculated and generated based on standardized data elements and constraint conditions, which fundamentally avoids human errors and ensures that the design results are 100% consistent with safety regulations and quality standards.

[0040] Strong correlation and inheritance: a full correlation data driven chain from global parameters to individual devices is established through the dynamic arrangement structure, any modification can be propagated and inherited, and the "one modification, whole linkage" is realized, which greatly facilitates the iteration and optimization of the design scheme.

[0041] Excellent reusability and adaptability: the interval template and the data element system are designed, so that the typical design scheme can be deposited and efficiently reused, and the new project only needs to adjust the key parameters to quickly generate an adapted new scheme, realizing the unification of standardization and customization. Lay the foundation for digital twin: the three-dimensional digital model generated by the method is "alive", which is an intelligent model driven by data, rather than a "dead" (static) geometric body. The three-dimensional digital model contains rich structured data elements, which can be seamlessly transmitted to the construction and operation stages, and provides a perfect high-precision and high-fidelity initial model for building a substation digital twin.

[0042] Further, the equipment interface is defined as a parameterized vector point carrying specific attributes, which helps to realize the standardization and accurate quantification of the equipment interface, and provides geometric shapes and data for automatic positioning, docking and automatic connection of conductors of the equipment.

[0043] Further, the design specification in the form of text (such as safety clearance) is converted into a parameterized and vectorized buffer constraint, so that the abstract specification clause becomes a quantifiable spatial rule that can be recognized and processed by a computer, providing spatial constraint basis for subsequent automatic arrangement and conflict detection.

[0044] Further, by creating structured bay template data set, the device configuration, connection relationship and arrangement rule of specific bay are modularized and templated, so that the bay can be quickly called and instantiated as a complete and reusable unit, improving the efficiency and standardization of arrangement design.

[0045] Further, by pre-storing voltage level and bay template of main wiring structure, bay template library is formed, so that the system can quickly match and call the corresponding standardized design scheme according to the design input conditions, ensuring the standardization and adaptability of the design.

[0046] Further, by adaptive layout optimization of overall space utilization, the device is quickly generated through template instantiation, and finally the position of each device is accurately calculated and ensured to be conflict-free under the rule restriction by using constraint solving, realizing the full-automatic three-dimensional arrangement from the whole to the local and driven by rules.

[0047] Further, based on rule-based conductor automatic generation, by identifying connection point pairs, matching standard parts in rule library and automatically calculating shape size, the selection, modeling and assembly automation of the conductor are realized, significantly improving the efficiency and accuracy of conductor design.

[0048] Further, an incremental updating mechanism is adopted, when the design is modified, only the affected part will be recalculated and updated, instead of starting from scratch, which greatly improves the efficiency of large-scale model modification and iterative design, and ensures the consistency of the internal correlation of the model.

[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0058] The present application realizes full automation, correlation and intelligent design of power distribution devices from equipment layout to conductor connection by constructing a parameterized and vectorized data element system, and is suitable for three-dimensional digital design platforms of substations of various voltage levels.

[0059] Reference Figure 1 The present application provides a data element driven dynamic layout method of a substation digital model, comprising the following steps: S1, constructing a data element system A core data element library driving three-dimensional layout of power distribution devices is established, and reference Figure 2 The core data element library comprises: Device interface element: extracting positioning reference points and wiring terminal points in three-dimensional digital models of various devices (such as circuit breakers, disconnectors, transformers, arresters and bushings) in substations, wherein the positioning reference points and the wiring terminal points are not ordinary geometric points, but parameterized vector points carrying unique ID, type (such as support type / hanging type, ABC three-phase), interface direction and connection specification attributes.

[0060] Layout control element: parameterizing and vectorizing requirements about safety clearance, operation and maintenance channel and transportation distance in design regulations and specifications. Specifically, it comprises: 1) minimum electrical distance between devices (such as phase-to-phase distance, device-to-ground distance), minimum distance between devices and framework and support, device-to-road / wall setback distance, minimum width of operation and maintenance channel; 2) defining the layout control element as a directional vector buffer zone. For example, a vector space area is defined, which is outward from the device shell, perpendicular to the device surface, and has a set value (safety clearance) of length, and any other device or conductor cannot intrude into the vector space area.

[0061] Space Template Element: Define "space" as the basic design unit of electrical distribution equipment. A space template is a structured data set, including: 1) Equipment list: all the types and quantities of equipment contained in the space; 2) Topology connection relationship: define the logical connection relationship between the equipment in the space, and between the equipment and the busbar; 3) Default layout rule: the default relative position relationship of all the equipment in a certain type of space; 4) Associated driving parameters include key parameters that drive the layout of the space, such as voltage level, equipment model sequence, reference Figure 3 .

[0062] S2, Establish data association and driving mechanism Forcedly associate the equipment interface element defined in S1 with the layout control element. For example, associate the wiring terminal of a circuit breaker with the "minimum ground distance of soft conductor" control element; associate the outer contour of the circuit breaker body with the "minimum electrical distance between equipment" control element.

[0063] Store the association relationship in a unified association relationship library to form a "equipment interface-control element" mapping matrix. This mapping matrix is the basis for subsequent automatic layout and conflict detection calculations.

[0064] S3, Define dynamic layout structure The core of the invention is to define a dynamic layout structure, which is an object-oriented, hierarchical data structure in computer memory, including: Distribution equipment layer: the highest level, including global parameters of the entire distribution equipment area, such as coordinate origin, rotation angle, voltage level and busbar configuration mode.

[0065] Space array layer: an array composed of multiple space instance objects. Each space instance is a specific implementation of the space template defined in S1, and the position of the space instance is dynamically calculated by its row and column number (i, j) in the array.

[0066] Space instance layer: each space instance is an intelligent object, including: 1) Parameterized equipment set: a collection of all device instances in the space. The initial position of each device instance is not an absolute coordinate, but a local coordinate relative to its space; 2) Local layout control element set: layout control elements that need to be followed within the space; 3) Connection relationship network: automatically generated conductor connection logic between devices based on topology connection relationship.

[0067] Global layout control element layer: layout control elements that act on the entire distribution equipment area, such as road boundaries, fence boundaries, hoisting areas.

[0068] S4, Parameter-driven and automatic generation User inputs or selects key driving parameters, such as voltage class U, main wiring structure S, bay number N, site length and width L x W.

[0069] The system automatically matches corresponding bay templates from the bay template library according to the voltage class U and the main wiring structure S.

[0070] According to the bay number N and the site length and width L x W, the adaptive layout algorithm is used to automatically calculate the optimal row-column arrangement and spacing of the bays, and to instantiate and generate bay instances. The adaptive layout algorithm can be based on a genetic algorithm or a constraint satisfaction algorithm optimizer.

[0071] For each bay instance, the system calls its built-in default placement rules to automatically place the devices inside it. The device placement process is a constraint solving process: the system takes the device interface points as control points and the arrangement control elements as constraint conditions to automatically calculate the optimal position of each device, ensuring that all constraints are met simultaneously without any conflicts.

[0072] S5, conductor automatic connection After all the device placement is completed, the conductor connection relationship network of each bay instance is traversed.

[0073] For each pair of device interface points that need to be connected, according to their types (such as tube terminal, soft wire terminal), voltage class, and current size, the appropriate conductor type (such as aluminum tube bus, steel-cored aluminum stranded wire) and connecting hardware are selected from the conductor rule library.

[0074] A three-dimensional digital model of the conductor that meets the mechanical and electrical requirements is generated and accurately connected to the interface points of the two devices.

[0075] S6, dynamic association update When the user modifies any global driving parameter (such as changing the voltage class, adjusting the bay number, or moving the busbar position), the modification action will trigger an incremental update event.

[0076] Instead of pushing down and redesigning, the change impact is passed layer by layer along the hierarchical relationship of the substation equipment and conductor dynamic arrangement structure, and only the affected parts are recalculated and updated.

[0077] For example, modifying the busbar height will trigger the recalculation of the suspension point positions of all devices connected to the busbar, and then trigger the adaptive adjustment of the positions of these devices, and finally trigger the automatic update of the conductors connected to these devices.

[0078] The entire process is automatically completed by data-driven without human intervention, perfectly realizing the "inheritance" of the design.

[0079] Taking the design of a 1000kV outdoor GIS distribution device as an example S101, data preparation stage A new project is created in the system, and the voltage level is set to 1000 kV, and the main wiring selection is one and a half breaker wiring. The system background automatically loads the data element library preset for the voltage level and wiring mode, and references Figure 5 , S102, parameter input and driving Input the basic size of the site and the spacing requirement, and the basic size of the site and the spacing requirement as the core driving parameter. For example, the basic size of the site is 500m x 90m, and the spacing requirement is 8 out-of-line intervals and 4 main transformer incoming line intervals.

[0080] S103, automatic generation of layout Reference Figure 4 and Figure 6 , through "automatic layout". Perform the following operations: 1) According to the voltage level and the wiring mode, match the "1000 kV out-of-line interval" template and the "1000 kV main transformer incoming line interval" template from the interval template library; 2) Call the adaptive layout algorithm to optimize the calculation with the site size as the boundary and the interval template size and the minimum channel requirement as the constraint. The adaptive layout algorithm outputs the optimal layout: 8 out-of-line intervals arranged on the same side, 4 main transformer incoming line intervals arranged on the other side, 51m out-of-line interval and main transformer incoming line interval, 50m out-of-line sleeve distance and main transformer incoming line sleeve distance, and 55m out-of-line frame distance and main transformer incoming line frame distance.

[0081] 3) According to the calculation results, the system instantiates 12 interval objects, i.e. 8 out-of-line intervals and 4 main transformer incoming line intervals, and arranges them into an interval array according to the calculated coordinates to obtain 12 interval instances.

[0082] 4) For each interval instance, the system reads the default layout rules and device list in its corresponding interval template, and arranges the corresponding device models of GIS, voltage transformer and surge arrester in turn. The position of each device model is determined in real time by constraint solving method: for example, when calculating the position of GIS, it needs to satisfy the vector buffer zone constraints defined by the body, out-of-line sleeve, surge arrester, voltage transformer, frame and adjacent phase-to-phase multiple layout control elements at the same time. For each device corresponding to the constraint, all devices are arranged, and after all devices are placed, global conflict detection is automatically performed to ensure that there is no collision.

[0083] S104, automatic connection of conductors After the device layout is completed, the system starts the conductor connection module, which connects the conductors between the devices to obtain the conductor connection model: 1) Scan the connection relationship network of each interval to identify the device interface point pairs that need to be connected.

[0084] 2) For the connection between the lightning arrester and the voltage transformer, a 6063G Φ200 / 180 aluminum alloy tubular bus is selected, and a continuous three-dimensional tubular bus model is automatically generated according to the coordinates of the terminal plate interface point of the device.

[0085] 3) For the connection between devices, a four-split expanded diameter heat-resistant aluminum alloy conductor, specifically JLHNK58K-1600 conductor, is selected according to the voltage and current values, and a corresponding soft conductor model is automatically generated, including accurate curvature and sag, and automatically assembling matching fittings such as strain clamps and device clamps, as shown in Figure 8 .

[0086] S105, dynamic adjustment, as shown in Figure 7 .

[0087] 1) After the layout is completed and reviewed, if the bay needs to be adjusted, the designer only needs to modify the control elements of the bay in the bay array management interface of the system, and this modification triggers a dynamic association update event.

[0088] 2) The system recognizes the change of the bay type and automatically replaces the original template with the "outgoing line bay" template.

[0089] 3) The system automatically calculates the arrangement of the devices in the new template (such as the outgoing line bay template and the incoming line bay template), adjusts the local layout of the bay and adjacent bays, and automatically deletes the original connection conductor, generating a new conductor connection model.

[0090] Based on the same technical concept, the application can also provide a data element driven dynamic layout system for a substation digital model, which includes a data element management module, a parameter receiving and analysis module, an intelligent layout generation module, a conductor automatic connection module, and a dynamic update engine. The data element management module is used to build a core data element library for driving the three-dimensional layout of the power distribution device, and the core data element library includes device interface elements, layout control elements, and bay template elements. The association mapping relationship between the device interface elements and the layout control elements is established and stored in the association relationship library. The parameter receiving and analysis module is used to obtain and analyze the global driving parameters. The intelligent layout generation module is used to execute the constraint solving and generate the three-dimensional layout model. The conductor automatic connection module is used to automatically generate the conductor connection model of each device in the three-dimensional layout model according to the bay template element and the three-dimensional layout model. The dynamic update engine is used to respond to the modification operation, schedule and execute the dynamic association update.

[0091] In addition, the application can also provide a computer readable storage medium, and the computer readable storage medium stores a computer program, and the computer program is executed by a processor to realize the data element driven dynamic arrangement method of a digital model of a substation.

[0092] The computer readable storage medium can include computer storage medium and communication medium. The computer storage medium includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information such as computer readable instructions, data structures, program modules or other data. The computer readable storage medium can include read only memory (ROM), random access memory (RAM), solid state disk (SSD) or optical disk. Among them, the random access memory can include resistance random access memory (ReRAM) and dynamic random access memory (DRAM).

[0093] The application not only greatly improves the design efficiency, but more importantly, ensures the accuracy and standardization of the design results through the data driven method. The three-dimensional digital model generated by the method contains structured data information, providing a high-quality data basis for subsequent digital construction and intelligent operation and maintenance, and effectively supporting the whole life cycle digital management of the substation. The application has been verified in a test project, showing good application prospect and popularization value.

[0094] The above is only the preferred embodiment of the application, but the protection scope of the application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the application, which should be covered within the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
