[0001] This invention relates to the technical field of power facility layout analysis, and in particular to a method and system for power facility layout analysis based on land spatial planning. Background Technology

[0002] Power facility layout analysis is an intelligent planning and decision-making process that integrates multi-source data to design the spatial location and form of the power system under the constraints of the national land spatial planning system, so as to achieve the coordinated goals of energy security, ecological protection and intensive and efficient use of space.

[0003] In the process of power facility layout analysis, the first step is to conduct on-site surveys manually, collect and manually overlay various maps and planning documents, and visually identify resource-rich areas and load centers on paper or basic electronic maps based on professional experience. Then, preliminary site and route plans are sketched by hand. Subsequently, through repeated consultations with multiple management departments, and relying on simplified calculations, empirical formulas and analogies, the load is manually estimated, power is balanced and the plan is adjusted to draw up formal power facility layout drawings and explanatory reports.

[0004] In the process of power facility layout analysis, the steps of manual on-site surveys, calculations, and scheme adjustments are too cumbersome and time-consuming, which reduces the efficiency of power facility layout analysis. Summary of the Invention

[0009] By adopting the above technical solutions, the specifications of auxiliary equipment and the location of auxiliary equipment can be obtained by analyzing the natural power generation load, thereby achieving refined reinforcement of the flexibility and reliability of the power system and improving the proactive adaptability of the planning scheme to the fluctuations of new energy sources.

S35: Use the markup layout specification as the layout specification.

[0011] By adopting the above technical solutions, the detection layout specifications are updated by analyzing the marked area, detection area, mobile device specifications, and underground layout characteristics. This allows for the introduction of mobile device adjustment and undergrounding strategies for dynamic resolution, ensuring that the layout plan complies with spatial control requirements and effectively guaranteeing the spatial feasibility and implementability of the planning results.

[0012] Optionally, methods for updating the detection layout specifications include: S40: Identify the underground layout equipment corresponding to the preset underground layout features and other equipment from the equipment specifications; S41: Based on the specifications of the testing equipment, other equipment, and underground layout equipment, to obtain matching equipment; S42: Retrieve the mating setting position of the mating equipment from the inspection layout specifications; S43: Combine and coordinate the location and underground layout equipment to obtain the underground layout range; S44: Collect soil testing information within the underground layout area; S45: Combine soil testing information with the underground layout scope to obtain underground layout specifications; S46: Update the inspection layout specifications based on underground layout specifications and underground layout equipment.

[0015] By adopting the above technical solution, the layout specifications are updated in real time through analysis of surrounding environmental information and layout specifications, thereby improving the feasibility of layout specification formation.

[0016] Optionally, methods for updating layout specifications include: S60: Determine whether the surrounding wind speed exceeds the baseline withstand wind speed; S61: If the surrounding wind speed does not exceed the baseline wind speed, continue uploading the layout specifications; S62: When the surrounding wind speed exceeds the benchmark wind speed, the difference between the surrounding wind speed and the benchmark wind speed is calculated as the wind speed deviation value. S63: The direction of change is detected based on layout specifications, wind speed deviation, and surrounding environmental information; S64: Update layout specifications based on detected change direction.

[0017] By adopting the above technical solutions and analyzing the surrounding environmental information to obtain new layout specifications, it is possible to design diversion channels to reduce the impact of surrounding wind on power facilities, thereby further improving the safety, environmental adaptability and long-term operational reliability of power facility layout analysis.

[0018] Alternatively, methods for updating layout specifications also include: S70: Retrieve the reference change direction of peripheral cables from the layout specifications; S71: Compare the detection change direction with the baseline change direction to update the layout specifications and upload them by detecting the change direction, or update the layout specifications by the baseline change direction. S72: Establish an environmental model based on surrounding environmental information; S73: Update the reference wind speed based on the direction of reference change; S74: Combine the environmental model, surrounding wind speed, and baseline wind speed to obtain the diversion specifications, and update the layout specifications based on the diversion specifications.

[0019] By adopting the above technical solution, the layout specifications are updated by comparing the inclusion of the detected change direction with the baseline change direction, thereby enabling the setting of drainage channels to actively optimize the local microclimate.

[0023] By adopting the above technical solutions, the initial diversion specifications of the diversion channel are adjusted to obtain the optimal diversion channel parameters. Then, by linking the layout of underground facilities and intelligently planning the coordinated construction sequence, the safety of the power facility layout is improved, and the intensive and efficient construction of the project and the minimization of ecological disturbance are further realized, thereby enhancing the overall economy and feasibility of the power facility layout.

Figure 2 This is a flowchart of a method for updating layout specifications according to an embodiment of the present invention. Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1 This application discloses a method for analyzing the layout of power facilities based on land spatial planning, including the following steps: S10: Data collection and detection area.

[0030] The detection area refers to the area where power facilities can be laid out, which can be obtained after pre-entry by the operator.

[0031] S11: Identify the range of natural clusters based on the detection area and the preset power generation type.

[0032] The power generation type is defined by technicians based on the region's natural resources, including photovoltaic, wind power, hydropower, and thermal fuels (around ports, docks, and coal mines).

[0033] The natural cluster range refers to the boundary area within the detection region that includes power generation types. This is determined by retrieving raster data from the National Meteorological Information Center database showing an annual average total solar radiation ≥ X kWh / m², and vector zoning data showing wind power density ≥ Y W / m² from the wind energy resource detailed survey database. The range of continuous polygons formed by overlay analysis and spatial clustering of the above data layers with the "Three Zones and Three Lines" land spatial data layer in GIS is defined as the natural cluster range.

[0034] In this embodiment, X and Y are threshold values ​​set by technicians to enable participation in natural power generation.

[0035] S12: Obtain the range of clusters to be used by detecting the region and the range of natural clusters.

[0036] Cluster usage range refers to the load area that requires power supply from electrical facilities. This is achieved by accessing the detailed land use planning database and extracting spatial distribution data for planned residential, commercial, and industrial construction land. Combined with population statistics and economic development forecasts, the projected power load for each planned plot is calculated using land use simulation or spatial load density index methods. The load data is then spatialized into a "load density heat map" on a GIS platform. Continuous areas on the map where the load density exceeds a preset threshold (e.g., 20 MW / km²) are designated as the cluster usage range.

[0037] Using the detailed land spatial planning database, land use simulation method, or spatial load density index method is common knowledge to those skilled in the art, and will not be elaborated here.

[0038] S13: Collect usage load and natural detection parameters of the cluster range.

[0039] The load used refers to the maximum load value predicted within the cluster scope, with reference to the maximum power load predicted in S12 as the load used.

[0040] Natural detection parameters refer to key performance indicators that quantify the resources and development conditions of each natural cluster. These parameters differ for different cluster types. Natural detection parameters can be obtained by the operator through data processing and analysis using other software.

[0041] For example, for photovoltaic clusters, the annual equivalent utilization hours (h) and the daily output fluctuation rate (% / min) are collected. The data comes from historical data of regional meteorological stations and output reports of photovoltaic power generation simulation software (such as PVsyst).

[0042] S14: Obtain the natural device specifications based on the natural detection parameters and the natural cluster range.

[0043] Natural equipment specifications refer to a list of core technical parameters for the power generation equipment required to develop natural clusters. Natural equipment specifications are determined by matching natural detection parameters (such as equivalent utilization hours) with the area of ​​the corresponding natural cluster from a pre-defined equipment lookup table. Natural equipment specifications include: the total installed capacity (MWp) and model of photovoltaic modules, the single-unit capacity (MW) and number of wind turbines, or the installed capacity (MW) and model of hydropower stations, etc.

[0044] The equipment comparison table stores the natural equipment specifications corresponding to different natural detection parameters and natural cluster ranges. The parameters in the equipment comparison table are set in advance by those skilled in the art based on actual conditions and will not be elaborated here.

[0045] S15: Obtain the natural power generation load based on the natural equipment specifications and natural detection parameters.

[0046] Natural power generation load refers to the load data formed after the power generation equipment of each natural cluster is connected to the grid. The load data generated by power system production simulation software (such as DigSILENT PowerFactory, PSASP) or dedicated wind and solar resource time series generation tools, characterized by the fluctuation characteristics of natural detection parameters, is used as the natural power generation load.

[0047] S16: Obtain the remaining variable load based on natural power generation load and usage load.

[0048] Residual variable load refers to the net load power that power facilities still need to output through conventional power sources, energy storage, or regional mutual assistance after deducting natural generation output. Under the condition of a unified time point, the total generation curve is obtained by summing all the natural cluster generation load curves generated in S15. Then, by comparing the total natural generation load with the total usage load, the net load that needs to be balanced by the system is obtained as the residual variable load.

[0049] The method for obtaining the remaining variable load is common knowledge to those skilled in the art and will not be elaborated here.

[0050] S17: Obtain the specifications of the testing equipment based on the remaining variable load.

[0051] The specifications of testing equipment refer to the specifications of the facilities required for the safe and stable operation of power facilities. The specifications of testing equipment are matched from the equipment comparison table by the remaining variable load.

[0052] The equipment comparison table stores the specifications of the testing equipment corresponding to the remaining variable load, which will not be elaborated here.

[0053] S18: A marked area is formed by comparing the specifications of the detection equipment with those of the natural equipment.

[0054] The marked area refers to the spatial area required for the installation of each piece of equipment in the power facility. A rule-based adaptive layout algorithm is adopted: taking the footprint of the equipment specifications as input, the area allowed for construction in the national land space plan as the boundary, and the minimum safe distance between equipment as a constraint, a greedy algorithm is used to perform the initial layout, generate the initial land boundary patches of each equipment, and set them together to form the marked area.

[0055] In this embodiment, the adaptive layout algorithm and the greedy algorithm are common knowledge to those skilled in the art, and will not be described in detail here.

[0056] S19: Merge the marked area, detection area, natural equipment specifications, and detection equipment specifications to form a layout specification, and upload the layout specification.

[0057] The layout specification refers to the final output specification used for arranging power facilities. It is obtained by analyzing the marked area and the detection area, and combining the installation location and other parameter data of the natural equipment specification and the detection equipment specification. The layout specification is then uploaded to the operator's terminal for the operator to view.

[0058] The verification methods for marked regions include: S20: Form a natural load curve based on natural power generation load and preset detection duration.

[0059] The testing duration is the time set by the technicians for conducting load testing.

[0060] The natural load curve refers to the two-dimensional curve formed by each natural generating load within the detection period. The curve is formed by retrieving the data of each natural generating load detected within the detection period from the power system production simulation software.

[0061] S21: Obtain the natural load type by comparing the natural load curve with the preset variation characteristics.

[0062] The variation characteristics are the power generation fluctuation curve characteristics of the natural power generation cluster set by technicians, such as volatility (wind power), periodicity (photovoltaics), and stability (hydropower, nuclear power, or coal power).

[0063] Natural load type refers to the type of power generation corresponding to a natural power generation cluster. By comparing the shape and variation characteristics of the natural load curve, the type corresponding to the variation characteristics that are consistent with the natural load curve is taken as the natural load type.

[0064] S22: Retrieve the auxiliary equipment specifications corresponding to the natural load type from the testing equipment specifications.

[0065] The auxiliary equipment specifications refer to the equipment that assists and coordinates with the natural power generation clusters of the natural load type. For example, when the natural load type is fluctuating, the auxiliary equipment specifications are those of the collection station / boost station. In this embodiment, the natural load type and the corresponding equipment are pre-mapped, which will not be elaborated here.

[0066] The specifications of the equipment corresponding to the natural load type are retrieved from the specifications of the testing equipment as auxiliary equipment specifications.

[0067] S23: Combine the auxiliary equipment specifications with the marked area to obtain the detection auxiliary position.

[0068] The detection auxiliary position refers to the various positions in the marked area where auxiliary equipment can be installed. Referring to S18, the position of the device corresponding to the specifications of the auxiliary equipment is retrieved from each marked area as the detection auxiliary position.

[0069] S24: Update the natural load curve based on the detection auxiliary location and auxiliary equipment specifications.

[0070] A new natural load curve for S20 is regenerated by installing auxiliary equipment of the specified specifications at each auxiliary testing location and resimulating the natural power generation load.

[0071] S25: Compare the natural load curve with the preset reference load curve to obtain the marker auxiliary position.

[0072] The baseline load curve is a load curve set by technicians to meet the requirements for safe operation of power facilities, with fluctuations within the permissible range.

[0073] The auxiliary marking position refers to the detection auxiliary position where the natural load curve and the reference load curve are consistent. By comparing the consistency between each natural load curve and the reference load curve, the detection auxiliary position corresponding to the natural load curve that is consistent with the reference load curve is taken as the auxiliary marking position.

[0074] S26: Update the marked area based on the marker auxiliary position and auxiliary equipment specifications.

[0075] Re-execute S18 after setting the auxiliary marking position and auxiliary equipment specifications to form a new marking area.

[0076] Methods for forming layout specifications include: S30: Compare the intersection of the marked area and the detection area to obtain the area outside the detection area.

[0077] The out-of-bounds area refers to the portion of the marked area that extends beyond the detection area. This is determined by performing spatial intersection analysis between the marked area and the detection area on the GIS (Geographic Information System) platform. The system automatically calculates the portion of the marked area that falls outside the detection area as the out-of-bounds area. The method of spatial intersection analysis on the GIS platform is common knowledge to those skilled in the art and will not be elaborated upon here.

[0078] S31: Retrieve the specifications of movable equipment within the marked range from the specifications of the testing equipment.

[0079] Mobile device specifications refer to device specifications that can change position. There are auxiliary device specifications with fixed positions in the marked area. Other devices besides auxiliary device specifications are retrieved from the marked range, and the device specifications that can be installed by changing position are taken as mobile device specifications.

[0080] S32: Combine the specifications of natural equipment, testing equipment, and movable equipment to obtain the testing layout specifications.

[0081] The detection layout specification refers to a comprehensive layout plan that includes all equipment (fixed and movable) and their initial positional relationships, including the plans corresponding to each movable device in different positions. The initial layout specification plan for each position is formed by inputting the specifications of the natural equipment, the detection equipment, and the movable devices into a 3D spatial model, and thus serves as the detection layout specification.

[0082] S33: Identify the layout area from the detected layout specifications.

[0083] The layout area refers to the space occupied by all devices in the detection layout specification. The layout area is identified by detecting the layout specification.

[0084] S34: Compare the inclusion of the layout area and the detection area to obtain the marked layout specifications, or combine the detection equipment specifications with the preset underground layout features to update the detection layout specifications, and obtain the marked layout specifications again.

[0085] Underground layout features are the equipment features of electrical facilities that are permitted to be installed underground, as defined by technical personnel.

[0086] The marking layout specification refers to the detection layout specification corresponding to the layout area that does not exceed the detection area. By analyzing the inclusion between each layout area and the detection area, the detection layout specification corresponding to the layout area included by the detection area is taken as the marking layout specification.

[0087] When none of the layout areas are included in the detection area, the new detection layout specifications are obtained by analyzing the specifications of the detection equipment and the underground layout characteristics, and the new layout areas are marked to obtain the layout specifications.

[0088] S35: Use the markup layout specification as the layout specification.

[0089] Use the markup layout specification as the layout specification.

[0090] Methods for updating the detection layout specifications include: S40: Identify the underground layout equipment and other equipment corresponding to the preset underground layout features from the detection equipment specifications.

[0091] Underground layout equipment refers to equipment that can be installed underground. Underground layout equipment is defined as equipment whose underground layout characteristics are identified from the specifications of the testing equipment.

[0092] Other equipment refers to equipment that cannot be installed underground. Equipment that is not designated for underground layout in the testing equipment specifications is considered other equipment.

[0093] S41: Based on the specifications of the testing equipment, other equipment and underground layout equipment to obtain matching equipment.

[0094] Matching equipment refers to other equipment that is connected to the underground layout equipment. Matching equipment is identified from the specifications of the testing equipment as other equipment that has a direct electrical connection (such as through cables or busbars) with the underground layout equipment.

[0095] S42: Retrieve the mating setting position of the mating equipment from the inspection layout specifications.

[0096] The matching setting position refers to the location where the matching equipment is installed. The matching setting position is obtained by retrieving the installation position of the matching equipment from the detection layout specifications.

[0097] S43: Combine and coordinate the location and underground layout equipment to obtain the underground layout range.

[0098] The underground layout scope refers to the area where underground equipment can be installed. By reading the footprint of the underground equipment and considering the need for underground cable trenches or pipe corridors to connect it with various matching locations, a minimum outer envelope polygon that can include the underground parts of all related equipment and connecting channels is generated in GIS as the underground layout scope.

[0099] S44: Collect soil testing information for the underground layout area.

[0100] Soil testing information refers to information about the soil within the underground layout area, including soil type, groundwater level depth, and shear wave velocity. This information can be retrieved from the urban engineering geological database.

[0101] S45: Combine soil testing information with the underground layout scope to obtain underground layout specifications.

[0102] The underground layout specification refers to the specifications for the layout of underground equipment. The underground layout specification is determined by matching the soil test information with the underground layout range from the equipment comparison table.

[0103] For example, if the soil type is soft soil and the groundwater level is high, the requirements of "foundation pit support is required" and "waterproofing grade is P8" will be automatically added to the underground layout specifications.

[0104] The equipment comparison table stores different soil testing information and underground layout specifications corresponding to the underground layout range, which will not be elaborated here.

[0105] S46: Update the inspection layout specifications based on underground layout specifications and underground layout equipment.

[0106] The underground layout specifications and underground layout equipment are incorporated into the inspection layout specifications to form a new inspection layout specification.

[0107] The methods for verifying layout specifications also include: S50: Collect environmental information about the surrounding area of ​​the marked area.

[0108] Surrounding environmental information refers to information about the environment surrounding the marked area, including temperature and humidity, wind direction and speed, surrounding topography, and surrounding trees. This can be achieved by accessing the gridded historical meteorological dataset from the National Meteorological Information Center to obtain typical annual wind speed, wind direction sequence, ambient temperature, and humidity data for the center of the marked area. The digital elevation model from the national land spatial information platform can be used to obtain surrounding terrain slope and aspect data. By interpreting high-resolution remote sensing satellite imagery and combining it with image recognition algorithms, the distribution and height information of vegetation (trees) within a certain buffer distance around the area are identified and integrated into the surrounding environmental information.

[0109] S51: Retrieve the surrounding wind speed from the surrounding environmental information.

[0110] The surrounding wind speed refers to the wind speed in the environment surrounding the marked area. It is determined by retrieving the maximum wind speed value from the surrounding environment information.

[0111] S52: Retrieve the baseline wind speed for external cables from the layout specifications.

[0112] The reference wind speed refers to the maximum wind speed that a cable exposed to the environment can withstand. It is determined by retrieving the model, diameter, tension, and safety factor of the external cable from the layout specifications, and then matching the reference wind speed from the equipment reference table based on the model, diameter, tension, and safety factor.

[0113] The equipment comparison table stores the reference wind speeds corresponding to the different models, diameters, tensions, and safety factors of external cables, which will not be elaborated here.

[0114] S53: Update layout specifications by comparing the surrounding wind speed with the baseline wind speed.

[0115] New layout specifications are derived by analyzing the extent to which the surrounding wind speed exceeds the baseline wind speed.

[0116] Methods for updating layout specifications include: S60: Determine whether the surrounding wind speed exceeds the baseline wind speed tolerance.

[0117] By determining whether the surrounding wind speed exceeds the baseline wind speed, it is possible to determine whether the peripheral cables in the layout specifications will experience abnormalities due to environmental influences.

[0118] S61: If the surrounding wind speed does not exceed the baseline wind speed, continue uploading the layout specifications.

[0119] If the surrounding wind speed does not exceed the baseline wind speed, it means that there will be no abnormality in the external cables, so continue to upload the layout specifications.

[0120] S62: When the surrounding wind speed exceeds the reference wind speed, the difference between the surrounding wind speed and the reference wind speed is calculated as the wind speed deviation value.

[0121] The wind speed deviation value refers to the deviation between the surrounding wind speed and the reference wind speed. When the surrounding wind speed does not exceed the reference wind speed, it indicates that the external cable is prone to abnormality. The wind speed deviation value is calculated by the difference between the surrounding wind speed and the reference wind speed.

[0122] S63: The direction of change is detected based on layout specifications, wind speed deviation, and surrounding environmental information.

[0123] The direction of change detection refers to the direction in which the path of the external cable is adjusted to reduce the impact of the surrounding wind on the external cable. This is done by retrieving the surrounding wind direction from the surrounding environment information and the path of the external cable from the layout specifications, calculating the angle between the path and the surrounding wind direction, and then matching the angle with the wind speed deviation value from the equipment reference table as the direction of change detection.

[0124] The equipment reference table stores the detection change direction corresponding to different included angles and wind speed deviation values. When the included angle remains unchanged, the larger the wind speed deviation value, the greater the detection change direction, which will not be elaborated here.

[0125] S64: Update layout specifications based on detected change direction.

[0126] New layout specifications are obtained by analyzing the direction of changes detected.

[0127] Reference Figure 2 Other methods for updating layout specifications include: S70: Retrieve the reference change direction of peripheral cables from the layout specifications.

[0128] The reference change direction refers to the direction in which the peripheral cable can be changed within the layout specification. Since there are still structures that can be changed within the layout specification, the reference change direction of the peripheral cable is retrieved from the layout specification.

[0129] S71: Compare the detection change direction with the baseline change direction to update the layout specifications and upload them, or update the layout specifications using the baseline change direction.

[0130] By analyzing the inclusion of the detected change direction and the reference change direction, when the reference change direction includes the detected change direction, it indicates that changes to the peripheral cables can be made. In this case, the layout specifications are updated and uploaded based on the detected change direction.

[0131] If the reference change direction does not include the detection change direction, it means that changes to peripheral cables cannot be made, and the layout specifications are updated using the reference change direction.

[0132] S72: Establish an environmental model based on surrounding environmental information.

[0133] An environmental model refers to a three-dimensional numerical computational model used for high-precision wind field simulation. By meshing the surrounding environmental information, a three-dimensional virtual geographic environment containing surface roughness information is constructed in computational fluid dynamics software. The methods for establishing three-dimensional numerical computational models are common knowledge to those skilled in the art and will not be elaborated upon here.

[0134] S73: Update the reference wind speed based on the reference change direction.

[0135] The correction factor is matched from the equipment reference table by the reference change direction, and the product of the correction factor and the reference wind speed is calculated as the new reference wind speed.

[0136] After changing the peripheral cable according to the reference change direction, the peripheral cable's ability to withstand wind speed is enhanced. Although the wind speed in the surrounding environment is still greater than the updated reference wind speed, it can reduce the design of subsequent drainage channels.

[0137] The equipment reference table stores correction coefficients corresponding to different reference change directions. The larger the reference change direction, the closer the external cable is to the surrounding wind direction, and the larger the correction coefficient. This will not be elaborated here.

[0138] S74: Combine the environmental model, surrounding wind speed, and baseline wind speed to obtain the diversion specifications, and update the layout specifications based on the diversion specifications.

[0139] The diversion specification refers to the specification of the ecological guideway designed to change the local wind field and reduce the wind speed at the cable. The diversion specification is obtained by analyzing the environmental model, the surrounding wind speed and the benchmark wind speed, and then the diversion specification is added to the layout specification to form a new layout specification.

[0140] Methods for obtaining traffic specifications include: S80: Update the environment model by setting the layout specifications.

[0141] The environment model will be regenerated based on the layout specifications corresponding to the direction of the baseline change.

[0142] S81: Retrieve the detected wind direction from the environmental model.

[0143] The detected wind direction refers to the wind direction of the surrounding environment, which is obtained by retrieving the detected wind direction from the environmental model (refer to the surrounding wind direction in S63).

[0144] S82: Determine the tolerance range of peripheral cables based on the detected wind direction and layout specifications.

[0145] The bearing capacity refers to the range of wind that the external cable can withstand under the detected wind direction. The bearing capacity is determined by retrieving the distribution range of the external cable in the layout specifications based on the detected wind direction.

[0146] S83: The direction of airflow is determined based on the detected wind direction and the available airflow range.

[0147] The diversion direction refers to the main extension direction of the guide channel. In this embodiment, the diversion channel is formed by clearing trees around the power facilities to indirectly change the wind force blowing towards the external cables. By performing fluid dynamics simulation analysis on the detected wind direction and the bearing range, the design direction of the diversion channel that affects the wind force under the detected wind direction and within the bearing range is taken as the diversion direction.

[0148] Simulation analysis in fluid mechanics is common knowledge to those skilled in the art and will not be elaborated upon here.

[0149] S84: Combine the drainage direction, environmental model, and preset initial drainage specifications to obtain each initial drainage channel.

[0150] The initial drainage specifications are the initial dimensions of the drainage channel design set by the technicians, for example, a design specification of 50 meters wide and 100 meters long with the drainage direction as the central axis.

[0151] The initial drainage channel refers to each drainage channel simulated in the environmental model with the drainage direction and initial drainage specifications at each location. By taking the drainage direction at each location as the central axis and simulating the design in the environmental model with the initial drainage specifications, the drainage channel designed in the environmental model is defined as the initial drainage channel.

[0152] S85: Simulate the new ambient wind speed corresponding to each initial diversion channel from the environmental model.

[0153] After designing each initial flow channel of S84, the environmental model is regenerated and the wind speed is simulated. The wind speed value of the simulated surrounding environment is retrieved from the regenerated environmental model as the surrounding wind speed.

[0154] S86: Compare the new ambient wind speed with the baseline wind speed and combine them with the initial diversion channel to obtain the marked diversion channel.

[0155] A marked guide channel refers to an initial guide channel where the new ambient wind speed matches the baseline wind speed. By analyzing the consistency between the new ambient wind speed and the baseline wind speed, the initial guide channel corresponding to the new ambient wind speed that matches the baseline wind speed is designated as the marked guide channel.

[0156] S87: Use the specifications marked in the environmental model as the drainage specifications.

[0157] The specifications marked in the environmental model for the drainage channel are used as the drainage specifications.

[0158] The methods for verifying layout specifications also include: S90: Compare the new ambient wind speed with the baseline withstand wind speed to define the initial diversion channel corresponding to the minimum ambient wind speed as the detection diversion channel.

[0159] The detection channel refers to the initial channel that has the greatest impact on the surrounding wind speed. By analyzing the consistency between the new surrounding wind speed and the reference wind speed, if the new surrounding wind speed is still inconsistent with the reference wind speed, the initial channel corresponding to the minimum surrounding wind speed is defined as the detection channel.

[0160] S91: Based on the direction of flow, detect changes in the initial flow specifications of the flow channel to re-simulate the surrounding wind speed.

[0161] Using the direction of airflow as the axis, the initial specifications of the detection channel are parametrically adjusted, for example, by gradually increasing its width or changing its starting or ending position to make it funnel-shaped. Each adjustment is followed by a re-run of the CFD simulation in the environmental model to obtain the new ambient wind speed.

[0162] S92: Calculate the difference in ambient wind speed before and after the update as the changed wind speed value.

[0163] The variable wind speed value refers to the improvement in the surrounding wind speed each time the initial diversion specification of the detection diversion channel is changed. Each time the specification is adjusted and changed using S91, the new surrounding wind speed is recorded and the difference between the surrounding wind speed before and after the update is calculated as the variable wind speed value.

[0164] S93: Calculate the quotient of the wind speed deviation value and the variable wind speed value as the correction coefficient.

[0165] The correction factor refers to the proportion of wind speed change offset by a unit change in specifications. It is calculated by dividing the wind speed deviation value by the changed wind speed value to obtain the correction factor, so as to facilitate rapid subsequent adjustment of specifications.

[0166] S94: Combine the initial drainage specifications before and after the update with the correction coefficient to obtain the detection drainage specifications.

[0167] The test diversion specification refers to the final specification of the diversion channel when the improvement in the surrounding wind speed is consistent with the wind speed deviation value. The final diversion channel specification is obtained by analyzing the initial diversion specifications and correction coefficients before and after the update.

[0168] For example: if the initial diversion specifications before and after the update are a 10-meter increase in width, a 1-m / s decrease in wind speed, and a wind speed deviation that needs to be reduced by 5m / s, then it is estimated that the width needs to be increased by about 50 meters.

[0169] S95: Retrieve the detection drainage range from the detection drainage specifications.

[0170] The detection and diversion range refers to the land boundary range of the optimized guideway, which is obtained by retrieving the detection and diversion range from the detection and diversion specifications.

[0171] S96: Compare the overlap between the diversion area and the underground layout area to obtain the overlap area.

[0172] The overlapping area refers to the area where the detection diversion area and the underground layout area overlap. By analyzing the overlap between the detection diversion area and the underground layout area, the area where the space overlaps between the detection diversion area and the underground layout area is taken as the overlapping area.

[0173] S97: Based on the overlapping area, underground layout equipment, and detection diversion specifications, the diversion formation sequence and diversion specifications are obtained to update the layout specifications.

[0174] The diversion formation sequence refers to the actual construction sequence of the diversion channels based on the tested diversion specifications. If there is overlap, a joint construction plan should be developed: within the overlapping area, the clearing work of the guide channel can be carried out simultaneously with the excavation of the foundation pit and the transportation of earthwork for underground facilities, achieving dual purposes with a single disturbance. This construction sequence is recommended as the diversion formation sequence, and the tested diversion specifications are included as diversion specifications and incorporated into the layout specifications along with the diversion formation sequence to guide the construction organization design.
