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 data element driven dynamic arrangement method and system for a substation digital model. 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 its 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:

[0003] 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 and time-consuming, and is prone to errors due to human error, resulting in low design efficiency.

[0004] Isolation and irrelevance: equipment arrangement and conductor (such as busbar, downlead, jumper) connection are two separate steps. After completing equipment positioning, designers need to manually select equipment connection terminals for conductor connection. When the position of a device changes, the conductor connected to the device will not be automatically updated and must be manually adjusted, resulting in repetitive work and connection errors.

[0005] Lack of inheritance and integrity: distribution devices are usually 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 and optimization is very high.

[0006] 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 reconfigure a large number of parameters according to the specific parameters of new projects (such as voltage level, equipment size, site conditions), which cannot achieve rapid parameterization adaptation and automatic generation of typical schemes.

[0007] 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

[0008] 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.

[0009] Another purpose of the present application is to realize the automation, intelligence and standardization of power distribution device design by constructing a complete system of parameterized and vectorized data elements, converting design specifications, device interfaces and spatial constraints into computable data to drive the automatic arrangement and update of a three-dimensional digital model.

[0010] 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:

[0011] 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;

[0012] S2, establishing an associated mapping relationship between the device interface elements and the arrangement control elements, and storing in an associated relationship library;

[0013] S3, obtaining global driving parameters, the global driving parameters comprising voltage levels and main wiring structures;

[0014] 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;

[0015] 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;

[0016] 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;

[0017] 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.

[0018] 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.

[0019] 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 setback distance between devices and roads or walls.

[0020] 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.

[0021] Further, in step S5, the pre-prepared interval template library pre-stores interval templates corresponding to voltage levels and main wiring structures.

[0022] 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:

[0023] S51, based on the number of intervals and the size of the site, calculate the optimal row-column arrangement and spacing of the intervals through adaptive layout, and generate an interval array;

[0024] S52, for each interval instance in the interval array, call the default arrangement rule in the interval template corresponding to the interval instance, and instantiate the devices in the interval template device list;

[0025] 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, calculating the position of each device in the interval local coordinate system by a constraint solving method, and performing global conflict detection.

[0026] The goal in step S5 is to determine the optimal position of all power devices in a given three-dimensional space (which can also be understood as an interval area), to ensure that it fully meets 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:

[0027] 1), input data:

[0028] The interval template object contains the list of devices to be arranged, the default topology connection relationship; the association relationship library provides the set of arrangement control elements associated with each device type; the 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.

[0029] 2) Preprocessing: formalized mathematical expression of constraints

[0030] First, abstract text specifications such as "safety clearance" are converted into mathematical constraints, and each mathematical constraint is expressed as an inequality or equation.

[0031] (1) Distance constraint:

[0032] Distance(Geometry_A,Geometry_B)≥D_min.

[0033] Where Geometry_A and Geometry_B are the outer bounding box or precise collision body of devices A and B. D_min is the minimum safety distance obtained from the association relationship library according to the device type and voltage level.

[0034] (2) Phase alignment constraint:

[0035] 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 three-phase device terminals are arranged in the correct order, facilitating conductor connection.

[0036] (3) Connection relationship constraint:

[0037] Abs(Device_A.terminal_position.y-Busbar.position.y)≤Tolerance; this constraint forces the device's wiring terminal and the busbar's suspension point to be within a certain tolerance range at the same height, creating conditions for smooth connection of subsequent conductors.

[0038] (4) Boundary constraint:

[0039] IsInside(Device_A,Operating_Zone)==True&&IsOutside(Device_AForbidden_Zone)==True; ensures that the device is located within the operating channel, while not exceeding the fence or entering the lifting forbidden zone.

[0040] 3) Solution process

[0041] The two-stage strategy of initial layout generation, conflict detection, and iterative solving is adopted, as follows, which clearly shows the complete closed-loop process from problem initialization to final solution verification:

[0042] (1) Construct the constraint satisfaction problem:

[0043] According to the input, define a variable set V = {V_pos_i, V_rot_i} representing the position and rotation for all devices within the current bay, and extract all related constraints from the association library to build a complete constraint satisfaction problem.

[0044] (2) Rule-based initial layout generation:

[0045] Before starting the iterative solving, an initial guess is provided according to heuristic rules to speed up convergence. Rule example: IF Device_Type == "Circuit Breaker" THEN Place Near The Front Center(Device).

[0046] This stage will use the default placement rules in the bay template to quickly generate a layout that roughly conforms to engineering conventions, which will have constraint conflicts.

[0047] (3) Conflict detection and iterative solving:

[0048] Detect conflicts in the layout of the previous step and optimize.

[0049] Conflict detection: Use the Separating Axis Theorem or spatial partitioning data structures (such as BVH trees) for collision detection, and list all device pairs that violate distance constraints, while checking other types of constraint violations.

[0050] After detecting conflicts, convert the conflicts into an optimization problem, with the goal of minimizing the degree of violation of all constraints.

[0051] The objective function is to minimize: Minimize(ΣViolation_Score(Constraint_i)), i.e., minimize the score of all violated constraints.

[0052] Solving method:

[0053] If the constraints are differentiable, use Newton's method to quickly find a local optimal solution, use sequential quadratic programming algorithms to handle nonlinear constraints, and when the solution space is complex and multi-peak, use genetic algorithms to find a global optimal solution or an approximate optimal solution.

[0054] Fine-tune the positions (V_pos_i) and rotations (V_rot_i) of the devices to generate a new layout with fewer conflicts.

[0055] (4) Loop iteration:

[0056] Conflict detection is performed again for the new layout, and the process of step (3) is looped until a solution satisfying all constraints is found or a maximum number of iterations is reached, and a current optimal solution is returned.

[0057] 4) Output and integration

[0058] Output: The final output is the final pose of each device, i.e., a transformation matrix containing [X, Y, Z, RotX, RotY, RotZ].

[0059] Three-dimensional model generation: After receiving the pose data, the final pose is applied to the corresponding parameterized device model, and an accurate device model is instantiated at the specified position in the three-dimensional scene.

[0060] Data association: Each instantiated device model still maintains the association with the device interface elements and arrangement control elements, providing data for subsequent conductor connection and dynamic updating.

[0061] Further, in step S6, generating a conductor connection model specifically includes the following steps:

[0062] S61, traversing the interval template elements to identify pairs of device interface points that need to be connected;

[0063] S62, according to the voltage level, current value, spatial distance and interface type of the device interface point pair, matching the optimal conductor and fitting type from the conductor rule library;

[0064] S63, according to the spatial coordinates of the device interface point pair, automatically calculating the shape and size of the conductor, and generating and assembling the three-dimensional digital model of the conductor and fitting.

[0065] Further, in step S7, the dynamic association update is incremental, 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 objects are recalculated and model updated.

[0066] In a second aspect, the present application provides a data element driven dynamic arrangement system for a substation digital model, which includes a data element management module, a parameter receiving and analysis module, an intelligent arrangement generation module, a conductor automatic connection module and a dynamic update engine.

[0067] The data element management module is used to build a core data element library for driving the three-dimensional arrangement of the power distribution device, the core data element library including a device interface element, an arrangement control element and a bay template element; and an associated mapping relationship between the device interface element and the arrangement control element is established and stored in an associated relationship library;

[0068] The parameter receiving and analyzing module is used to acquire and analyze global driving parameters, and match corresponding bay templates from a preset bay template library; the bay template library is generated after fixing the bay template element;

[0069] 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 bay template and the associated relationship library by a constraint solving method, and the position of a device in the three-dimensional arrangement model is determined by parameterization driving of the device interface element and the arrangement control element;

[0070] 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 bay template element in combination with the three-dimensional arrangement model;

[0071] The dynamic updating engine is used to respond to a modification operation, and schedule and execute dynamic associated updating.

[0072] In a third aspect, the application further provides 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 implement the data element driving-based dynamic arrangement method of the digital model of a transformer substation.

[0073] Compared with the prior art, the application has at least the following beneficial effects:

[0074] Improved design efficiency: based on the global driving parameters, corresponding bay templates are matched from a preset bay template library; and according to the bay template and the associated relationship library, a three-dimensional arrangement model of the power distribution device is automatically calculated and generated, which completely liberates designers from repetitive manual dragging and adjusting work, shortens the design scheme generation from hours to minutes, and improves the efficiency by more than one order of magnitude;

[0075] 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.

[0076] Strong association and inheritance: a full associated data driving chain from global parameters to a single device is established through a dynamic arrangement structure, any modification can be propagated and inherited, which realizes "one modification, whole linkage", greatly facilitates design scheme iteration and optimization.

[0077] Excellent reusability and adaptability: The interval template and data element system are designed to enable typical design schemes to be refined and reused efficiently. New projects only need to adjust key parameters to quickly generate adapted new schemes, achieving the unification of standardization and customization.

[0078] Laying the foundation for digital twinning: The three-dimensional digital model produced by this method is "alive" and driven by intelligent data models, rather than "dead" (static) geometry. The rich structured data elements contained in the three-dimensional digital model can be seamlessly transferred to the construction and operation stages, providing a perfect high-precision and high-fidelity initial model for building a digital twinning body for the substation.

[0079] Further, defining the equipment interface as a parameterized vector point carrying specific attributes helps to achieve standardization and accurate quantification of the equipment interface, providing geometric shapes and data for automatic positioning, docking, and automatic connection of conductors.

[0080] Further, converting design specifications in text form (such as safety clearance) into parameterized and vectorized buffer constraints makes abstract specification clauses into quantifiable spatial rules that can be recognized and processed by computers, providing spatial constraint basis for subsequent automatic arrangement and conflict detection.

[0081] Further, by creating a structured interval template data set, the device configuration, connection relationship, and arrangement rules of a specific interval are modularized and templated, allowing the interval to be called and instantiated as a complete and reusable unit, improving the efficiency and standardization of layout design.

[0082] Further, by pre-storing interval templates for voltage levels and main wiring structures, a template library is formed, allowing the system to quickly match and call corresponding standardized design schemes based on design input conditions, ensuring the normativity and adaptability of the design.

[0083] Further, through adaptive layout optimization for overall space utilization, rapid generation of equipment through template instantiation, and accurate calculation of the position of each device under rule constraints and conflict-free conditions through constraint solving, the whole automatic three-dimensional layout from the overall to the local is realized, driven by rules.

[0084] Further, based on rule-based conductor automatic generation, by identifying connection point pairs, matching standard parts in the rule library, and automatically calculating the shape and size, the selection, modeling, and assembly automation of conductors are realized, significantly improving the efficiency and accuracy of conductor design.

[0085] Further, an incremental update mechanism is adopted, when the design is modified, only the affected part will be recalculated and updated, instead of starting from scratch, greatly improving the efficiency of large-scale model modification and iterative design, and ensuring the consistency of the internal correlation of the model.

[0094] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are some of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0095] The application realizes full automation, correlation and intelligent design of power distribution devices from device 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.

[0096] REFERENCE Figure 1 The application provides a substation digital model dynamic arrangement method based on data element driving, comprising the following steps:

[0097] S1, constructing a data element system

[0098] Establish a core data element library for driving the three-dimensional layout of the power distribution device, refer to Figure 2 The core data element library includes:

[0099] Device interface element: Extract the positioning reference points and wiring terminal points in the three-dimensional digital model of various devices in the substation (such as circuit breakers, disconnectors, transformers, arresters, bushings). The positioning reference points and 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.

[0100] Layout control element: Parameterize and vectorize the requirements in design regulations and specifications regarding safety clearance, operation and maintenance channel, and transportation distance. Specifically including: 1) Minimum electrical distance between devices (such as phase-to-phase distance, device-to-ground distance), minimum distance between device and framework and support, device-to-road / wall setback, minimum width of operation and maintenance channel; 2) Define the layout control element as a directional vector buffer zone. For example, define a vector space area that is outward from the device shell, perpendicular to the device surface, and has a set value (safety clearance) length. Any other device or conductor must not intrude into the vector space area.

[0101] Bay template element: Define "bay" as the basic design unit of the power distribution device. A bay template is a structured data set, including: 1) Device composition list, i.e. all device types and quantities contained in the bay; 2) Topological connection relationship: define the logical connection relationship between devices within the bay and between devices and busbars; 3) Default layout rule: the default relative position relationship of all devices within a bay of a certain type; 4) Associated driving parameters including key parameters for driving the layout of the bay, such as voltage level, device model sequence, refer to Figure 3 .

[0102] S2, establish data association and driving mechanism

[0103] Force the association between the device interface elements defined in S1 and the layout control elements. For example, associate the wiring terminal of a circuit breaker with the "minimum ground distance of flexible conductor" control element; associate the outer contour of the circuit breaker body with the "minimum electrical distance between devices" control element.

[0104] Store the association relationship in a unified association relationship library to form a "device interface-control element" mapping matrix. This mapping matrix is the basis for subsequent automated layout and conflict detection calculations.

[0105] S3, define dynamic layout structure

[0106] The core of the present application is to define a dynamic arrangement structure, which is an object-oriented, hierarchical data structure in computer memory, including:

[0107] Power distribution device layer: the highest level, including the global parameters of the entire power distribution device area, such as coordinate origin, rotation angle, voltage level and bus configuration method.

[0108] Bay array layer: an array composed of multiple bay instance objects. Each bay instance is a specific embodiment of the bay template defined in S1, and the position of the bay instance is dynamically calculated by its row and column number (i, j) in the array.

[0109] Bay instance layer: each bay instance is an intelligent object, including: 1) parameterized device set: the set of all device instances in the bay. The initial position of each device instance is not an absolute coordinate, but a local coordinate relative to the bay it is in; 2) local layout control element set: the layout control elements that need to be followed within the bay; 3) connection relationship network: the conductor connection logic between devices automatically generated based on topological connection relationship.

[0110] Global layout control element layer: layout control elements that act on the entire power distribution device area, such as road boundaries, fence boundaries, hoisting areas.

[0111] S4, parameter-driven and automatic generation

[0112] User input or selection of key driving parameters, such as voltage level U, main wiring structure S, number of bays N, site length and width L x W.

[0113] The system automatically matches the corresponding bay template from the bay template library according to the voltage level U and the main wiring structure S.

[0114] According to the number of bays N and the site length and width L x W, an adaptive layout algorithm is used to automatically calculate the optimal row-column arrangement method and spacing of the bays, and to instantiate the bay instances. The adaptive layout algorithm can be based on a genetic algorithm or a constraint satisfaction algorithm optimizer.

[0115] For each bay instance, the system calls its built-in default layout rules to automatically place the devices inside it. The device placement process is a constraint solving process: the system takes the device interface point as the control point and the layout control element as the constraint condition to automatically calculate the optimal position of each device, ensuring that all constraints are satisfied simultaneously without any conflicts.

[0116] S5, automatic conductor connection

[0117] After all the devices are arranged, the conductor connection relationship network of each bay instance is traversed.

[0118] For each pair of device interface points that need to be connected, select the appropriate conductor type (such as aluminum busbar, steel-cored aluminum stranded wire) and connecting hardware from the conductor rule library according to its type (such as tube terminal, soft wire terminal), voltage level, current size, etc.

[0119] Generate a three-dimensional digital model of the conductor that meets the mechanical and electrical requirements, and accurately connect it to the interface points of the two devices.

[0120] S6, dynamic association update

[0121] When the user modifies any global driving parameter (such as changing the voltage level, adjusting the number of intervals, moving the busbar position), the modification action will trigger an incremental update event.

[0122] Instead of pushing down to redesign, the change impact is passed layer by layer along the hierarchical relationship of the substation equipment and conductor dynamic layout structure, and only the affected parts are recalculated and updated.

[0123] For example, modifying the busbar height will trigger the recalculation of the suspension point positions of all devices connected to the busbar, then trigger the adaptive adjustment of the positions of these devices, and finally trigger the automatic update of the conductors connected to these devices.

[0124] The entire process is data-driven and automatically completed without human intervention, perfectly realizing the "inheritance" of the design.

[0125] Take the design of a 1000kV outdoor GIS distribution device as an example

[0126] S101, data preparation phase

[0127] Create a new project in the system, set the voltage level to 1000kV, and select the one-and-a-half breaker connection as the main connection. The system background automatically loads the data element library preloaded for this voltage level and connection mode, and references Figure 5 ,

[0128] S102, parameter input and driving

[0129] Input the basic site size and interval requirements, which are the core driving parameters. For example, the basic site size is 500m x 90m, and the interval requirement is 8 outgoing line intervals and 4 main transformer incoming line intervals.

[0130] S103, automatic generation of layout

[0131] Refer to Figure 4 and Figure 6 , and perform "automatic layout" as follows:

[0132] 1) According to the voltage level and the wiring mode, match the "1000kV outgoing line interval" template and the "1000kV main transformer incoming line interval" template from the interval template library;

[0133] 2) Call the adaptive layout algorithm to perform optimization 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 outgoing line intervals arranged on the same side, 4 main transformer incoming line intervals arranged on the other side, the outgoing line interval and the main transformer incoming line interval 51m, the outgoing line bushing spacing and the main transformer incoming line bushing spacing 50m, and the outgoing line structure spacing and the main transformer incoming line structure spacing 55m.

[0134] 3) According to the calculation results, the system instantiates 12 interval objects, i.e. 8 outgoing 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.

[0135] 4) For each interval instance, the system reads the default arrangement rules and device list in the corresponding interval template, and arranges the device models corresponding to the GIS, voltage transformer and surge arrester in turn. The position of each device model is determined in real time by the constraint solving method: for example, when calculating the position of the GIS, the vector buffer constraints defined by the body, outgoing line bushing, surge arrester, voltage transformer, structure and adjacent phase-to-phase arrangement control elements need to be satisfied at the same time. For each device corresponding constraint, all devices are arranged, and after all devices are placed, global conflict detection is automatically performed to ensure that there is no collision.

[0136] S104, automatic connection of conductors

[0137] After the device arrangement is completed, the system starts the conductor connection module, which arranges the connection between the conductors to obtain a conductor connection model:

[0138] 1) Scan the connection relationship network of each interval to identify the device interface point pairs that need to be connected.

[0139] 2) For the connection between the surge arrester and the voltage transformer, select a 6063G Φ200 / 180 aluminum alloy tubular busbar, and automatically generate a continuous three-dimensional tubular busbar model according to the coordinates of the device terminal plate interface points.

[0140] 3) For the connection between devices, select a four-split expanded diameter heat-resistant aluminum alloy conductor according to the voltage and current values, specifically JLHNK58K-1600 conductor, and automatically generate the corresponding soft conductor model, including accurate curvature and sag, and automatically assemble the matching fittings such as strain clamps and device clamps, refer to Figure 8 .

[0141] S105, dynamic adjustment, refer to Figure 7 .

[0142] 1) After the arrangement of the wiring is completed and the review is finished, if the interval needs to be adjusted, the designer only needs to modify the control element of the interval in the interval array management interface of the system, and the modification triggers a dynamic association update event.

[0143] 2) The system identifies that the interval type is changed, and automatically replaces the original template with the "outgoing interval" template.

[0144] 3) The system automatically calculates the arrangement of the equipment in the new template (such as the outgoing interval template and the incoming interval template), adjusts the local layout of the interval and the adjacent interval, automatically deletes the original connection conductor, and generates a new conductor connection model.

[0145] Based on the same technical concept, the application can also provide a data element driven dynamic arrangement system of a digital model of a substation, 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.

[0146] The data element management module is used to construct a core data element library for driving the three-dimensional arrangement of a 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.

[0147] The parameter receiving and analyzing module is used to acquire and analyze the global driving parameters.

[0148] The intelligent arrangement generation module is used to execute the constraint solving and generate the three-dimensional arrangement model.

[0149] The conductor automatic connection module is used to automatically generate the conductor connection model of each device in the three-dimensional arrangement model according to the interval template element and in combination with the three-dimensional arrangement model.

[0150] The dynamic update engine is used to respond to the modification operation, and schedule and execute the dynamic association update.

[0151] 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 the digital model of the substation.

[0152] 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 storage of 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, etc. Among them, the random access memory can include resistance random access memory (ReRAM) and dynamic random access memory (DRAM).

[0153] The application not only greatly improves the design efficiency, but more importantly, ensures the accuracy and standardization of the design results in a data-driven manner. 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.

[0154] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
