Description

Technical Field

[0001] This application relates to the technical field of smart grids, and particularly to a method and system for optimizing equipment layout in the design of power transmission and transformation projects. Background Art

[0002] With the increasing demand for electricity, traditional power transmission and transformation project designs are gradually facing many challenges, especially in equipment layout and space utilization. Currently, the design of power transmission and transformation projects usually relies on manual experience for layout, and the process of collecting design drawing information and regional division lacks automation, resulting in problems such as unreasonable space utilization, redundant configuration, and low layout efficiency in equipment layout. Even when using computer-aided design (CAD) software, these tools are mainly limited to the drawing of two-dimensional drawings and lack intelligent optimization functions, making it difficult to achieve automated and refined equipment layout in complex environments. The optimization of equipment layout directly affects the operation efficiency of power transmission and transformation projects. Especially in the smart grid architecture, unreasonable equipment layout may lead to low power transmission efficiency, energy waste, frequent equipment failures, thereby increasing operation and maintenance costs and reducing the stability and intelligence level of the power grid system.

It should be understood that this application is not limited by the exemplary embodiments described here. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts belong to the scope of protection of this application. Additionally, it should be noted that for the sake of description, only the parts related to this application are shown in the accompanying drawings rather than all of them.

[0025] Embodiment 1. Please refer to the attached Figure 1 , this application provides a method for optimizing the equipment layout in the design of power transmission and transformation projects. Among them, the method for optimizing the equipment layout in the design of power transmission and transformation projects is executed by a system for optimizing the equipment layout in the design of power transmission and transformation projects. The method for optimizing the equipment layout in the design of power transmission and transformation projects specifically includes the following steps:

[0026] S100: Obtain the design drawing information and distribution characteristic data of the target power transmission and transformation project, and based on the distribution characteristic data, divide the design drawing information into regions to obtain N power transmission and transformation project regions.

[0027] Furthermore, S100 of this application includes:

[0028] Based on the distribution characteristic data, map and label the design drawing information to obtain the transmission and transformation project design distribution data; obtain the engineering area division factor set, where the engineering area division factor set includes equipment function, terrain boundary, load density, and equipment safety level; according to the engineering area division factor set, analyze and identify the transmission and transformation project design distribution data to obtain the transmission and transformation project factor parameter set; based on the transmission and transformation project factor parameter set, divide the design drawing information into regions to obtain N transmission and transformation project regions.

[0029] Specifically, obtain the design drawing information of the target transmission and transformation project, that is, the drawing that describes the overall layout, equipment installation location, wiring path, key nodes, etc. of the transmission and transformation project, which contains all equipment layouts, design specifications, electrical connections, etc. of the substation, and is usually made using design tools such as CAD. The design drawings of the transmission and transformation project may include the locations of equipment such as transformers, circuit breakers, grounding systems, cable channels, control rooms, etc., as well as the distribution of current and voltage. The distribution characteristic data is the data information that describes the spatial, functional, load and other characteristics of each equipment in the design drawing, which describes the distribution, functional requirements and operating conditions of these equipment in the physical space, such as the location, capacity, type of the equipment, etc. Based on this, the distance between equipment, power demand, operating environment, etc. can be determined.

[0030] According to the distribution characteristic data, map and label the design drawing information, associate the distribution characteristic data with the corresponding positions in the design drawing, and map these data onto the drawing through a mapping and labeling tool (such as GIS software). For example, label the rated power of the transformer or the safety level of the circuit breaker on the design drawing to ensure that there is a clear correspondence between the functional characteristics and positions of each equipment, forming a standardized design drawing.

[0031] Obtain the engineering area division factor set, that is, the key factor set for dividing the transmission and transformation project area, and determine how to divide the entire transmission and transformation project area in the design drawing into multiple functional areas or sub-areas according to specific requirements, including equipment function, terrain boundary, load density, equipment safety level, etc. According to the equipment function, the roles or functions of different equipment can be determined. For example, equipment such as transformers, circuit breakers, and switches undertake different tasks; according to the terrain boundary, the impact of the natural environment and land use on the power grid layout can be determined; according to the load density, the power demand per unit area within the region can be determined; according to the equipment safety level, the safety guarantee required for the equipment can be determined.

[0032] According to the factor set of project area division, the design distribution data of the power transmission and transformation project is parsed and identified to identify the key parameters therein and perform identification, including information such as the function, type, load, etc. of each device within the area. Parsing and identification is to apply the factor set of project area division (such as load density, device function, etc.) to the design distribution data to identify and classify each device and the area where it is located. That is, according to the factor set of project area division, the area where each device is located is parsed to identify parameters such as the device function, load demand, safety level, etc. of each area. After analysis according to the factor set of project area division, a factor parameter set of the power transmission and transformation project is obtained, including detailed information such as the electrical equipment configuration, function, load demand, etc. of each area.

[0033] According to the factor parameter set of the power transmission and transformation project, the entire power transmission and transformation project area on the design drawing is divided to obtain N power transmission and transformation project areas, where N represents the number of divided areas and is a positive integer. Here, mainly based on the design drawing and distribution characteristic data, combined with factors such as device function, terrain, load density, and safety level, the area is divided. Each area has its own characteristics in terms of function, device requirements, load density, etc., and can be configured and optimized for equipment targeted. Through area division and load density analysis, the most suitable equipment can be configured in different areas, thereby improving the overall stability and operation efficiency.

[0034] Furthermore, the present application further includes the following steps:

[0035] According to the precision requirement of the power transmission and transformation project area division, set the area grid division density; perform area grid division on the design drawing information according to the area grid division density to obtain the power transmission and transformation project grid area; perform clustering analysis on the power transmission and transformation project grid area based on the factor parameter set of the power transmission and transformation project to obtain the grid area clustering result; perform boundary division adjustment on the design drawing information based on the grid area clustering result to obtain the N power transmission and transformation project areas.

[0036] Specifically, according to the precision requirement of the power transmission and transformation project area division, that is, the requirement for the degree of detail of the power transmission and transformation project area division, set the density of grid division. The higher the grid division density, the more detailed the area division, and the equipment and load information within each area can more accurately reflect the actual situation. If the precision requirement is low, the grid division density can be set low. For example, if the project complexity is high and the load demand within the area is high, usually a higher grid division density is adopted to set a smaller grid size, such as a 10-meter × 10-meter grid.

[0037] The entire design drawing is meshed according to the regional grid division density to obtain the grid area of the power transmission and transformation project, that is, the small areas obtained through regional grid division. For the grid area of the power transmission and transformation project on the design drawing, the grid areas are divided into different categories through clustering analysis algorithms (such as K-means clustering, DBSCAN, etc.), and the areas with similar characteristics are grouped together. That is to say, according to equipment functions, terrain boundaries, load density, equipment safety levels, etc., clustering analysis is performed on the grid areas, and they are grouped according to the similarity of the parameter sets.

[0038] According to the results of the clustering analysis, that is, the clustering results of the grid areas, the boundary division of the design drawing information is adjusted, the equipment and functions of the same type of areas are merged, and the area size and layout are optimized according to load density, safety requirements, etc. For example, after clustering analysis, a certain area has a high load density and its equipment functions are relatively complex. It may be necessary to expand the division boundary of this area and arrange more redundant equipment in this area. For areas with low load density, the boundary of this area may be reduced and redundant equipment may be reduced.

[0039] Through grid division and clustering analysis, N optimized power transmission and transformation project areas are obtained. Each area is optimized and adjusted according to factors such as its functional requirements, load density, and safety level to improve the efficiency and reliability of the overall layout. Through detailed grid division and clustering analysis, the specific requirements of each area are accurately reflected. Within each area, equipment can be reasonably configured according to factors such as load density and safety requirements, avoiding unnecessary redundant configurations and improving the utilization efficiency of resources.

[0040] S200: Invoke the layout data space of the power transmission and transformation project through the smart grid, perform effect evaluation fitting on the layout data space of the power transmission and transformation project, and construct a layout simulation module for the power transmission and transformation project.

[0041] Furthermore, S200 of this application includes:

[0042] According to the layout data space of the power transmission and transformation project, determine the characteristic data of the power transmission and transformation project, equipment layout data, and corresponding layout effect data; construct an evaluation index set for the layout effect of the power transmission and transformation project, perform an impact degree evaluation on the evaluation index set for the layout effect of the power transmission and transformation project, and determine an impact factor set for the evaluation index; based on the impact factor set for the evaluation index and the evaluation index set for the layout effect of the power transmission and transformation project, perform effect weighted evaluation on the corresponding layout effect data to obtain equipment layout effect data; perform simulation effect fitting on the characteristic data of the power transmission and transformation project, equipment layout data, and the equipment layout effect data, and construct the layout simulation module for the power transmission and transformation project.

[0043] Furthermore, this application also includes the following steps:

[0044] Perform association impact data mining based on the above-mentioned evaluation index set for the layout effect of the power transmission and transformation project to obtain a data set of layout effect indexes for the power transmission and transformation project; perform positive normalization processing on the data set of layout effect indexes for the power transmission and transformation project to obtain a standard data set of layout effect indexes for the power transmission and transformation project; perform ratio value calculation and information entropy calculation on the standard data set of layout effect indexes for the power transmission and transformation project to obtain an information entropy set of layout effect indexes for the power transmission and transformation project; perform entropy weight calculation on the evaluation index set for the layout effect of the power transmission and transformation project based on the information entropy set of layout effect indexes for the power transmission and transformation project to determine the impact factor set of the evaluation indexes for the effect.

[0045] Specifically, call the data space of the layout of the power transmission and transformation project through the smart grid to obtain all information related to the power transmission and transformation project, including equipment layout, functional requirements, load requirements, regional characteristics, etc. The data space of the layout of the power transmission and transformation project contains all design information, equipment layout, functional requirements, load information, etc. in the power transmission and transformation project. According to the data space of the layout of the power transmission and transformation project, determine the characteristic data of the power transmission and transformation project, equipment layout data, and corresponding layout effect data. Among them, the characteristic data is the data describing the basic characteristics of the power transmission and transformation project, such as voltage level, capacity, line length, etc.; the equipment layout data includes equipment location, quantity, type, connection method, etc.; the layout effect data includes actual effect data such as load distribution, equipment interval, and safety.

[0046] Define a series of evaluation indexes according to the requirements and actual working conditions of the power transmission and transformation project to measure the equipment layout effect, that is, the evaluation index set for the layout effect of the power transmission and transformation project. Evaluate the influence degree of the evaluation index set for the layout effect of the power transmission and transformation project to identify the key factors affecting the layout effect.

[0047] First, perform association impact data mining on the evaluation index set for the layout effect of the power transmission and transformation project, analyze the relationships between various factors (such as equipment layout, load density, safety, etc.) in the design of the power transmission and transformation project, and extract the factors that have a significant impact on the layout effect. Conduct a correlation analysis on various factors in the design of the power transmission and transformation project, mine the correlations between factors, and obtain a data set of layout effect indexes for the power transmission and transformation project. Association impact data mining is a method of analyzing the correlations between different variables through data mining technology. By mining the relationships between equipment layout and other design factors, identify which factors have an important impact on the layout effect.

[0048] Perform positive normalization processing on the data set of layout effect indexes for the power transmission and transformation project, and standardize the data to a unified range (such as 0 to 1) to eliminate the influence of dimensional differences during calculation. Positive normalization processing is a data preprocessing method, usually used to process data with different dimensions. Positive normalization is to convert the values of each data according to certain rules into the same range (usually between 0 and 1) to eliminate the influence of dimensions on comparison.

[0049] Calculate the proportional values for the standard power transmission and transformation project effectiveness index dataset, process different evaluation indicators according to relative proportions. Usually, compare the data of each indicator with other data to calculate its relative proportion, and determine which indicators have a greater impact on the whole and which have a smaller impact. For each indicator, calculate the proportional value through the proportional relationship between its standardized value and the standardized values of other indicators. Based on the proportional values, calculate the information entropy of each evaluation indicator to measure its contribution to the overall layout optimization. The calculation of information entropy can reveal which indicators have a greater impact on the system and which have a smaller impact. Information entropy calculation is a measure to evaluate the uncertainty or amount of information, and to assess the information contribution of each evaluation indicator in the equipment layout. After completing the calculation of proportional values and information entropy, obtain the information entropy value set (i.e., information entropy set) of each evaluation indicator, which reflects the contribution and influence of each indicator.

[0050] According to the information entropy value of each indicator, calculate its weight to obtain the influence factor set of evaluation indicators. Entropy weight calculation is to calculate the information entropy of each indicator to obtain the weight of each evaluation indicator. A larger weight indicates a greater impact on the layout effect. Through data mining and standardization processing, accurately identify the key factors affecting the layout effect. Through information entropy calculation and entropy weight calculation, the influence of each evaluation indicator can be quantified, ensuring that the optimization process focuses on the most critical indicators, avoiding over-reliance on unimportant factors, discovering potential problems and making adjustments in the early stage, thereby improving the overall efficiency and stability of the equipment layout and reducing the later maintenance cost.

[0051] According to the influence factor set of the effectiveness evaluation indicators and the evaluation indicator set of the power transmission and transformation project layout effect, conduct weighted evaluation on the corresponding layout effect data to obtain the score of this layout effect. Multiply the score of each evaluation indicator by its corresponding influence factor, and then calculate the weighted average value to form a comprehensive layout effect score. According to the characteristic data of the power transmission and transformation project, equipment layout data and equipment layout effect data, conduct simulation effect fitting to construct a power transmission and transformation project layout simulation module, which is used to simulate and evaluate the effects of different layout schemes, so as to determine the deficiencies of the schemes and conduct targeted optimization. Through the analysis and simulation fitting of the power transmission and transformation project layout data space, the effects of different layout schemes can be evaluated to ensure that the finally selected scheme can maximize the system operation efficiency, reduce energy consumption, improve safety and optimize space utilization.

[0052] S300: Use the power transmission and transformation project layout simulation module based on the power transmission and transformation project layout data space to sequentially optimize the equipment layout for the N power transmission and transformation project areas, and determine the equipment layout schemes for the N power transmission and transformation areas.

[0053] Furthermore, S300 of this application includes:

[0054] Based on the design distribution data of the N power transmission and transformation project areas, traversing and matching analysis is sequentially carried out in the power transmission and transformation project layout data space to obtain N area-adapted equipment layout schemes; the power transmission and transformation project layout simulation module is used to respectively carry out simulation evaluation on the N area-adapted equipment layout schemes to obtain the simulation effects of the N area layout schemes; based on the simulation effects of the N area layout schemes, iterative search and optimization are carried out on the N area-adapted equipment layout schemes to determine the power transmission and transformation area equipment layout schemes for the N areas.

[0055] Specifically, according to the design distribution data of the N power transmission and transformation project areas, that is, the equipment layout scheme and its spatial distribution of each area, which cover information such as equipment type, location, and function allocation of each area. According to the design distribution data, traversing the power transmission and transformation project layout data space, the area-adapted equipment layout schemes corresponding to each area are matched, that is, the N area-adapted equipment layout schemes. Each adapted equipment layout scheme is a scheme suitable for the current area in the power transmission and transformation project layout data space, and multiple equipment layout schemes may be matched for each area.

[0056] The N area-adapted equipment layout schemes are respectively input into the power transmission and transformation project layout simulation module for simulation evaluation to determine the actual effects of these schemes. Based on the simulation effects of the N area layout schemes, iterative search and optimization are carried out on the N area-adapted equipment layout schemes, that is, the scheme with the best overall effect among all the schemes is found, and the power transmission and transformation area equipment layout schemes for the N areas are determined. These schemes are the best equipment layout schemes for the current area after simulation verification. By quickly screening out multiple reasonable layout schemes through traversing and matching analysis, and through simulation evaluation and iterative optimization, the finally obtained equipment layout scheme can ensure the efficiency and safety of the power transmission and transformation project during actual operation, and ensure the obtainment of an efficient, stable and safe power transmission and transformation project layout scheme.

[0057] S400: Based on the power transmission and transformation area equipment layout schemes for the N areas, three-dimensional modeling is carried out to generate an initial engineering equipment layout model, and abnormal identification and marking are carried out on the initial engineering equipment layout model to obtain equipment layout abnormal feature information.

[0058] Furthermore, S400 of this application includes:

[0059] According to the application safety standards for power transmission and transformation projects, determine the abnormal identification rules for equipment layout. The abnormal identification rules for equipment layout include equipment distance constraints, equipment distribution constraints, and power operation constraints. Perform abnormal identification and detection on the initial engineering equipment layout model according to the abnormal identification rules for equipment layout to obtain a set of abnormal points for equipment layout. Perform type identification and abnormal scoring on the set of abnormal points for equipment layout to obtain a set of abnormal point features, and fuse the set of abnormal point features into a list to obtain the abnormal feature information for equipment layout.

[0060] Specifically, according to the equipment layout plans of N power transmission and transformation project areas in N power transmission and transformation areas, determine the equipment positions, equipment spacing, load requirements, safety standards, etc. in each area. Input the equipment layout plans of the N areas into 3D modeling software to accurately display the equipment positions, sizes, and relationships between equipment in 3D space. Each equipment is placed according to the requirements of the layout plan in terms of position and size to form a complete 3D model. The initial engineering equipment layout model is the equipment layout model generated for the entire power transmission and transformation project area through 3D modeling technology, which shows the specific positions, spacings, installation directions, etc. of all equipment in the entire area.

[0061] Obtain the application safety standards for power transmission and transformation projects, that is, the safety specifications and standards that guide the design, construction, and operation processes of power transmission and transformation projects, to ensure that power equipment and the power grid meet the requirements in terms of safety, stability, reliability, etc. during operation. According to the safety standards of power transmission and transformation projects, set the abnormal identification rules for equipment layout, covering the safety distance between equipment (equipment distance constraints), the rationality of equipment distribution (equipment distribution constraints), and the load requirements and operation restrictions of the power system (power operation constraints). The abnormal identification rules for equipment layout are the standards and conditions used to judge whether the equipment layout meets the design requirements, and help to discover potential safety hazards or unreasonable layout situations.

[0062] According to the abnormal identification rules for equipment layout, perform abnormal identification and detection on the initial engineering equipment layout model to find all places that do not meet the safety standards. For example, input the positions and types of all equipment in the power transmission and transformation project area into a computer simulation system. According to the abnormal identification rules for equipment layout, it is judged that the spacing between some transformers and distribution equipment is less than the specified value, and these will be marked as abnormal points. The set of abnormal points for equipment layout is the position set of all detected abnormal points in the initial equipment layout model, and these points represent the problems or non-compliant places in the layout, such as too close equipment distance, unreasonable distribution, etc.

[0063] Identify the types of abnormal points in the equipment layout set to determine the specific abnormality here, such as abnormal equipment distance, abnormal equipment distribution, abnormal power operation, etc. Each point will be classified according to its location area, equipment type, and its relationship with other equipment. The types of abnormalities can be identified based on preset design rules, such as equipment spacing requirements, load-bearing limits, safety regulations, etc. Score each abnormal point according to the type and severity of each abnormal point, usually determined by the impact of the abnormality on equipment safety, performance, maintenance, etc. For example, an abnormality with insufficient spacing may pose a greater safety hazard to the equipment, so the score is higher; while an abnormality with a slightly overloaded load has a lower score.

[0064] The abnormal point feature set refers to the set of all key information describing the abnormal point, including the type of abnormality, severity of abnormality, scope of influence, recommended improvement measures, etc. For example, the feature set of an identified abnormal point includes: type of abnormality: insufficient equipment spacing, severity: high, abnormal impact: will cause adjacent equipment to malfunction, recommendation: increase the equipment spacing to 5m. Perform list fusion on the abnormal point feature sets, merge the abnormal point feature information from multiple sources into a comprehensive list, and comprehensively evaluate the features of all abnormal points. After multiple abnormal points (such as insufficient equipment spacing, overload, etc.) undergo type identification and scoring, their respective feature sets will be collected into a list, and the features of all abnormal points will be merged according to certain rules, such as sorting by type, severity, etc.

[0065] By determining the rules for identifying equipment layout abnormalities according to safety standards, automatically identify the abnormal points in the layout model, perform scoring and feature information fusion, timely discover problems that may lead to equipment failures, overloads, or safety hazards, and prioritize solving high-risk layout problems to ensure overall safety and stability.

[0066] S500: Based on the equipment layout abnormal feature information, perform global optimization analysis on the initial engineering equipment layout model to determine the equipment layout plan for the power transmission and transformation project.

[0067] Furthermore, S500 of this application includes:

[0068] Perform global optimization analysis on the initial engineering equipment layout model based on the equipment layout abnormal feature information to obtain the optimization threshold of the equipment layout plan parameters; according to the optimization threshold of the equipment layout plan parameters, initialize the population of the equipment layout plan; use the power transmission and transformation project layout simulation module to perform optimization integration output within the population of the equipment layout plan to determine the equipment layout plan for the power transmission and transformation project.

[0069] Randomly select and evaluate within the population of equipment layout plans using the power transmission and transformation project layout simulation module to obtain the simulation effects of multiple layout plans; expand the population of equipment layout plans through crossover and mutation according to the simulation effects of the multiple layout plans to obtain an updated population of equipment layout plans; perform global iterative optimization within the updated population of equipment layout plans until a preset termination condition is reached to determine the equipment layout plan for the power transmission and transformation project.

[0070] Specifically, based on the abnormal feature information of equipment layout, perform global optimization analysis on the initial engineering equipment layout model. After considering all abnormal feature information, through a global optimization method (such as genetic algorithm, particle swarm optimization, etc.), comprehensively optimize the equipment layout to ensure that the layout parameters of all equipment can reach the best state while meeting the constraint conditions. The abnormal feature information of equipment layout includes all abnormal problems that may affect equipment layout. Global optimization based on this can adjust the layout targeted to ensure that the final layout plan meets the design standards.

[0071] According to the results of global optimization analysis, determine the optimization thresholds for each parameter of the equipment layout plan. The optimization threshold refers to the parameter range or constraint conditions of the equipment layout plan, and all plans must be adjusted within these threshold ranges. For example, the optimization threshold for equipment spacing may be from 5 meters to 10 meters, and the optimization threshold for load distribution may be from 80% to 100%, etc.

[0072] Initialize the population of equipment layout plans according to the optimization thresholds of the equipment layout plan parameters, that is, generate a series of equipment layout plans to form the initialized population of equipment layout plans. Each layout plan in the population is a possible configuration of equipment layout, including a certain number of equipment, equipment spacing, load distribution, etc. parameters, and meets the requirements of the optimization thresholds.

[0073] Use the power transmission and transformation project layout simulation module to perform simulation evaluation on each plan in the population of equipment layout plans, simulate the effects of different layout plans in the actual project, and evaluate the feasibility and performance of each plan. Optimize and adjust each layout plan according to the simulation results, and finally output an optimal layout plan. The integrated output of optimization refers to that in the optimization process, through continuous adjustment and iteration, finally output a comprehensively optimized equipment layout plan. This output result has undergone multiple simulations and evaluations and can meet all design requirements and performance indicators.

[0074] Specifically, a solution is randomly selected from the population of equipment layout solutions and input into the substation and transmission line project layout simulation module for simulation. The functions of the equipment, their coordination with each other, load distribution, spatial layout, safety, etc. are simulated to evaluate the operation effect in the actual project, and the simulation effects of multiple layout solutions are obtained. The purpose of random selection is to increase diversity during the optimization process and avoid falling into local optimal solutions. Through random selection, more possible layout solutions can be explored.

[0075] Based on the simulation effects of multiple layout solutions, the population of equipment layout solutions is expanded through crossover and mutation to generate new layout solutions, thereby increasing the diversity of the population of equipment layout solutions. The crossover operation generates new solutions by exchanging some parameters of two solutions; the mutation operation is to make small random adjustments to certain parameters. The purpose of crossover and mutation is to prevent the optimization process from stagnating at local optimal solutions and to expand the solution space. For example, two layout solutions are selected, and according to the simulation effects of the solutions, their equipment spacing and load distribution parameters are crossed to obtain a new layout solution, ensuring adjustment in a more optimal direction; then, the two layout solutions are mutated to make them more in line with the optimization goal.

[0076] Based on the solutions expanded through crossover and mutation, the population of equipment layout solutions is updated to obtain an updated population of equipment layout solutions. Global iterative optimization is performed within the updated population of equipment layout solutions, and the optimal layout solution is searched through multiple rounds of iteration. In each round of iteration, each layout solution in the current population is evaluated, and solutions with better performance are selected for crossover and mutation, and then a new population is formed for the next round of optimization until the preset termination conditions (such as the number of iterations, error threshold, etc.) are reached. The preset termination conditions are the stop conditions set during the optimization process, which determine when to stop the iteration, including a fixed number of iterations, the achievement of the optimization goal, the error being less than the preset threshold, etc. After multiple rounds of iteration and optimization, an optimal equipment layout solution is finally determined. This solution meets the design requirements in terms of equipment spacing, load distribution, safety, etc., and can achieve efficient, safe, and low-energy consumption operation in the actual project.

[0077] Exemplarily, assume that the population of equipment layout solutions contains 4 layout solutions. After simulating these four solutions, the simulation effect scores obtained are: Solution 1 is 75, Solution 2 is 85, Solution 3 is 90, and Solution 4 is 70. The two relatively poor solutions, Solution 1 and Solution 4, are crossed and mutated to adjust the position of the distribution cabinet and the equipment spacing, and then simulated again. The simulation effect scores obtained are: Solution 5 is 81, Solution 6 is 80, Solution 7 is 93, and Solution 8 is 79. Through multiple rounds of iterative optimization, the layout solution with the highest score is finally selected.

[0078] The equipment layout simulation module randomly selects, cross - mutates and expands the population of equipment layout schemes for the transmission and transformation project, and performs iterative optimization to improve the equipment layout design efficiency of the transmission and transformation project, optimize the design scheme, enhance the safety and operation efficiency of the overall power system, and finally determine the optimal equipment layout scheme that meets all design standards and performance requirements.
