Description

Technical Field

[0001] This invention relates to the field of power transmission line engineering technology, and in particular to a method and apparatus for determining the degree of variation in power transmission line engineering. Background Technology

[0002] As the design depth, optimization, and other constraints on route selection increase in existing transmission line projects, the actual construction route of the transmission lines differs significantly from the route planned during the environmental impact assessment (EIA) stage, leading to major project changes. Consequently, the significant alterations to the transmission line plan prevent the project from passing the environmental protection acceptance inspection upon completion. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method and device for determining the degree of change in transmission line engineering, which can determine the degree of change in transmission line engineering and realize accurate quantification and intelligent early warning of the degree of change in transmission line.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] A method for determining the degree of variation in a power transmission line project includes:

[0006] Obtain the primary geographic information of the power transmission line project and the secondary geographic information of the environmental impact assessment of the power transmission line project;

[0007] Based on the first geographic information and the second geographic information, determine the change information between the first geographic information and the second geographic information;

[0008] The degree of change in the transmission line project is determined based on the aforementioned change information.

[0009] Optionally, obtaining the first geographical information of the power transmission line project includes:

[0010] Obtain the coordinates of the first path, the name of the first electromagnetic and noise sensitive point, and the names of the ecologically sensitive areas along the first line, including nature reserves, scenic spots, and drinking water source protection areas, during the transmission line construction drawing stage of the transmission line project.

[0011] Optionally, obtaining the second geographic information for the environmental impact assessment of the transmission line project includes:

[0012] Obtain the coordinates of the second path, the name of the second electromagnetic and noise sensitive point, and the names of the ecologically sensitive areas along the second line, including nature reserves, scenic spots, and drinking water source protection areas, during the environmental impact assessment phase of the power transmission line project.

[0013] Optionally, determining the change information between the first geographic information and the second geographic information based on the first geographic information and the second geographic information includes:

[0014] The first variation in path length during the construction drawing stage compared to the environmental impact assessment stage is determined based on the first path coordinates and the second path coordinates.

[0015] The second variation range is determined based on the first path coordinates and the second path coordinates, which shows the cumulative length of the lateral displacement of the line in the construction drawing stage exceeding the set value compared to the environmental impact assessment stage.

[0016] Based on the first and second electromagnetic and noise sensitive point names, determine the third change range of the electromagnetic and acoustic environment sensitive targets added in the construction drawing stage compared to the environmental impact assessment stage.

[0017] Based on the names of the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the first route and the names of the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the second route, the fourth change in the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the route is determined in the construction drawing stage compared to the environmental impact assessment stage.

[0018] The change information is determined based on the relationship between the first change range and the first set interval, the second change range and the second set interval, the third change range and the third set interval, and the fourth change situation and the fourth set situation.

[0019] Optionally, determining the change information based on the relationship between the first change magnitude and the first set interval, the second change magnitude and the second set interval, the third change magnitude and the third set interval, and the fourth change condition and the fourth set condition includes:

[0020] If the first change exceeds the first set range, the second change exceeds the second set range, the third change exceeds the third set range, or the fourth change meets any of the conditions of the fourth set condition, the change information is determined to be a major change.

[0021] If any one of the following conditions is met: the first change range meets the first set range, the second change range meets the second set range, or the third change range meets the third set range, the change information is determined to be a major change warning.

[0022] If the three conditions are met—the first change range being less than the first set interval, the second change range being less than the second set interval, and the third change range being less than the third set interval—the change information is determined to be an allowed change.

[0023] Optionally, the first change range is the percentage increase in path length during the construction drawing stage compared to the environmental impact assessment stage relative to the total path length during the environmental impact assessment stage.

[0024] The second variation range is the percentage of the cumulative length of the lateral displacement of the route in the construction drawing stage exceeding the set value compared to the environmental impact assessment stage, relative to the total path length in the environmental impact assessment stage.

[0025] The third variation range is the percentage of electromagnetic and acoustic environmental sensitive targets added in the construction drawing stage compared to the environmental impact assessment stage, relative to the total number of electromagnetic and acoustic environmental sensitive targets in the environmental impact assessment stage.

[0026] The fourth change is whether there are any newly added ecologically sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the route during the construction drawing stage compared to the environmental impact assessment stage.

[0027] Optionally, determining the degree of change in the transmission line project based on the change information includes:

[0028] Based on the change information, the degree of change in the transmission line project is determined as a major change, a major change warning, or a permissible change.

[0029] The present invention also provides a device for determining the degree of variation in power transmission line engineering, comprising:

[0030] The acquisition module is used to acquire the first geographic information of the transmission line project and the second geographic information of the environmental impact assessment of the transmission line project;

[0031] The processing module is used to establish a three-dimensional real-scene model based on the first geographic information and the second geographic information; determine the change information between the first geographic information and the second geographic information based on the three-dimensional real-scene model; and determine the degree of change of the power transmission line project based on the change information.

[0032] The present invention also provides a computing device, comprising: a processor and a memory storing a computer program, wherein the computer program, when executed by the processor, performs the method described above.

[0033] The present invention also provides a computer-readable storage medium storing instructions that, when executed on a computer, cause the computer to perform the method described above.

[0034] The above-described solution of the present invention has at least the following beneficial effects:

[0035] The present invention utilizes a four-dimensional index—path length change rate, cumulative percentage of lateral displacement exceeding limits, proportion of newly added sensitive targets, and intrusion status of ecologically sensitive areas—to comprehensively quantify the degree of change. Post-completion inspection is initiated at the construction drawing stage, avoiding the discovery of problems only during the acceptance phase. A 25%-30% warning range is set, allowing for minor adjustments to the path within technically reasonable limits, reducing unnecessary environmental impact assessment changes. The addition of ecologically sensitive areas directly triggers a major change warning, ensuring that regulatory red lines are not crossed. This shifts from passive rectification to proactive optimization significantly reduces engineering risks. The combination of quantitative indicators and flexible thresholds supports scientific decision-making and reduces human error. The automated process of warning → optimization → release achieves a highly efficient closed loop for change management. Attached Figure Description

[0038] Figure 3 This is a schematic diagram of the module of the transmission line engineering variation determination device of the present invention. Detailed Implementation

[0039] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0040] like Figure 1 As shown, an embodiment of the present invention provides a method for determining the degree of variation in a power transmission line project, including:

[0041] Step 11: Obtain the first geographic information of the transmission line project and the second geographic information of the environmental impact assessment of the transmission line project;

[0042] Step 12: Determine the change information between the first geographic information and the second geographic information based on the first geographic information and the second geographic information;

[0043] Step 13: Determine the degree of change in the transmission line project based on the change information.

[0044] This invention determines the degree of change in power transmission line projects by comparing first and second geographic information, achieving accurate quantification and intelligent early warning of the degree of change in power transmission lines, and significantly improving the compliance and economy of the project.

[0045] Specifically, in step 11, obtaining the first geographical information of the power transmission line project includes:

[0046] Obtain the coordinates of the first path, the name of the first electromagnetic and noise sensitive point, and the names of the ecologically sensitive areas along the first line, including nature reserves, scenic spots, and drinking water source protection areas, during the transmission line construction drawing stage of the transmission line project.

[0047] In step 11, obtaining the second geographical information for the environmental impact assessment of the transmission line project includes:

[0048] Obtain the coordinates of the second path, the name of the second electromagnetic and noise sensitive point, and the names of the ecologically sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the second line in the environmental impact assessment stage of the power transmission line project.

[0049] In an optional embodiment of the present invention, step 12, determining the change information between the first geographic information and the second geographic information based on the first geographic information and the second geographic information, includes:

[0050] Step 121: Determine the first change in path length in the construction drawing stage compared to the environmental impact assessment stage based on the first path coordinates and the second path coordinates.

[0051] Step 122: Determine the second variation range of the cumulative length of the lateral displacement of the line in the construction drawing stage compared to the environmental impact assessment stage that exceeds the set value based on the first path coordinates and the second path coordinates.

[0052] Step 123: Determine the third variation range of the electromagnetic and acoustic environment sensitive targets added in the construction drawing stage compared to the environmental impact assessment stage based on the first electromagnetic and noise sensitive point names and the second electromagnetic and noise sensitive point names.

[0053] Step 124: Based on the names of the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the first route and the names of the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the second route, determine the fourth change in the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the route during the construction drawing stage compared to the environmental impact assessment stage.

[0054] Step 125: Determine the change information based on the relationship between the first change range and the first set interval, the second change range and the second set interval, the third change range and the third set interval, and the fourth change situation and the fourth set situation.

[0055] In this embodiment, the increase in path length (first variation) is quantified to intuitively reflect the environmental impact of changes in project scale. Analysis of cumulative lateral displacement length (second variation) accurately identifies key sections where the construction route deviates from the environmental impact assessment design. Identification of newly added sensitive targets (third variation) enables dynamic tracking of electromagnetic / noise sensitive points, allowing for timely detection of omissions in the environmental impact assessment. Analysis of changes in ecologically sensitive areas (fourth variation) ensures that protection measures for special areas such as nature reserves are updated synchronously to avoid ecological damage. Through multi-dimensional data fusion analysis, quantitative assessment and intelligent judgment of engineering design changes are achieved.

[0056] In an optional embodiment of the present invention, step 125, determining the change information based on the relationship between the first change amplitude and the first set interval, the second change amplitude and the second set interval, the third change amplitude and the third set interval, and the fourth change situation and the fourth set situation, includes:

[0057] Step 1251: If the first change range exceeds the first set range, the second change range exceeds the second set range, the third change range exceeds the third set range, or the fourth change condition meets any of the conditions of the fourth set condition, the change information is determined to be a major change.

[0058] Step 1252: If any one of the following conditions is met: the first change range meets the first set interval, the second change range meets the second set interval, or the third change range meets the third set interval, the change information is determined to be a major change warning.

[0059] Step 1253: If the three conditions of the first change range being less than the first set interval, the second change range being less than the second set interval, and the third change range being less than the third set interval are met, the change information is determined to be allowed to change.

[0060] Specifically, the first change is the percentage increase in path length during the construction drawing stage compared to the environmental impact assessment stage, relative to the total path length during the environmental impact assessment stage.

[0061] The second variation range is the percentage of the cumulative length of the lateral displacement of the route in the construction drawing stage exceeding the set value compared to the environmental impact assessment stage, relative to the total path length in the environmental impact assessment stage.

[0062] The third variation range is the percentage of electromagnetic and acoustic environmental sensitive targets added in the construction drawing stage compared to the environmental impact assessment stage, relative to the total number of electromagnetic and acoustic environmental sensitive targets in the environmental impact assessment stage.

[0063] The fourth change is whether there are any newly added ecologically sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the route during the construction drawing stage compared to the environmental impact assessment stage.

[0064] The first set range is 25%-30%, the second set range is 25%-30%, the third set range is 25%-30%, and the fourth set situation is that there are newly added ecologically sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the route in the construction drawing stage compared with the environmental impact assessment stage.

[0065] In this embodiment, if any change indicator exceeds the limit (path length exceeding 30%, cumulative lateral displacement exceeding 30%, new sensitive points exceeding 30%, or new ecologically sensitive areas), it is judged as a major change. This avoids situations where a single indicator fails to meet the standard while other indicators are severely exceeded, thus preventing missed detection. The addition of ecologically sensitive areas directly triggers a major change, ensuring that regulatory red lines are not crossed. An early warning is triggered when any change indicator is between 25% and 30%. This allows design units to fine-tune the path within a technically reasonable range, avoiding unnecessary optimization costs due to a "one-size-fits-all" approach. If all change indicators are less than 25% and no new sensitive areas are added, the change is deemed permissible. Low-risk projects are quickly approved, shortening the approval cycle.

[0066] Specifically, the percentage of the cumulative length of the lateral displacement exceeding the set value during the construction drawing stage compared to the environmental impact assessment stage, relative to the total path length during the environmental impact assessment stage (the second variation range), includes:

[0067] according to The lateral displacement of the route determined during the construction drawing stage compared to the route determined during the environmental impact assessment stage.

[0068] Among them, L i The lateral displacement of the route during the construction drawing stage and the route during the environmental impact assessment stage, (x i y i (m) represents the coordinates of each point on the route during the construction drawing stage. i n i ) represents the coordinates of each point on the route during the environmental impact assessment stage, and i is the index value of each point, i = 1, 2, 3, ..., n;

[0069] according to The cumulative length by which the lateral displacement of the route during the construction drawing stage exceeds the set value compared to the route during the environmental impact assessment stage.

[0070] Where, ∑L 超 L represents the cumulative length by which the lateral displacement of the route during the construction drawing stage exceeds a set value compared to the route during the environmental impact assessment stage. i L represents the lateral displacement of the route during the construction drawing stage and the route during the environmental impact assessment stage. 阈 Here, i is a set value (specifically, 500m), and i is the index value of each point, i = 1, 2, 3, ..., n;

[0071] according to The second variation is determined by the percentage of the cumulative length of the lateral displacement exceeding the set value during the construction drawing stage compared to the environmental impact assessment stage, relative to the total path length during the environmental impact assessment stage.

[0072] Where P is the percentage of the cumulative length of the lateral displacement of the route in the construction drawing stage exceeding the set value compared to the environmental impact assessment stage, relative to the total path length in the environmental impact assessment stage (second variation range), ∑L 超 L represents the cumulative length by which the lateral displacement of the route during the construction drawing stage exceeds a set value compared to the route during the environmental impact assessment stage. 环总长 This refers to the path length during the environmental impact assessment stage.

[0073] In this embodiment, the second variation range, by quantifying the cumulative impact of excessive lateral displacement, provides a scientific and efficient environmental compliance assessment tool for transmission line projects. This is further enhanced by its synergistic effect with other indicators.

[0074] In an optional embodiment of the present invention, step 13, determining the degree of change in the transmission line project based on the change information, includes:

[0075] Step 131: Determine the degree of change in the transmission line project based on the change information as a major change, a major change warning, or a permissible change.

[0076] When the changes to a transmission line project are considered significant, a warning will be issued regarding the construction drawing route. The construction unit should provide feedback to the design unit, which should then optimize the route during the construction drawing design phase. The design unit should conduct a comprehensive assessment with the construction unit from technical, environmental, economic, and constraining factors to determine the final construction route.

[0077] When the degree of change in a transmission line project reaches the warning level for major changes, an early warning will be issued for the construction drawing route plan. The construction unit should provide feedback on the results to the design unit, and the design unit should optimize and adjust the route plan during the construction drawing design stage to bring the construction drawing route plan within the warning line to prevent major changes in the final construction route plan.

[0078] If the degree of change in the transmission line project is within the permissible range, then the route plan is approved.

[0079] In this embodiment, the approach shifts from reactive post-completion rectification to proactive optimization during the construction drawing phase, significantly reducing project risks. Quantitative indicators and flexible thresholds support scientific decision-making and reduce human error. An automated process of early warning → optimization → release achieves a highly efficient closed loop for change management.

[0080] This invention achieves comprehensive quantification of the degree of change through four-dimensional indicators: path length change rate, cumulative percentage of lateral displacement exceeding limits, proportion of newly added sensitive targets, and intrusion status of ecologically sensitive areas. Post-completion inspection is initiated at the construction drawing stage, avoiding problems being discovered only during acceptance. A 25%-30% warning range is set, allowing for minor adjustments to the path within technically reasonable limits, reducing unnecessary environmental impact assessment changes. The addition of ecologically sensitive areas directly triggers a major change warning, ensuring that regulatory red lines are not crossed. This shifts from passive rectification to proactive optimization, significantly reducing project risks. The combination of quantitative indicators and flexible thresholds supports scientific decision-making and reduces human error. An automated process of warning → optimization → release achieves a highly efficient closed loop for change management.

[0081] like Figure 2 As shown, a specific implementation process of the present invention is as follows:

[0082] First, the construction unit collects the coordinates of the first path, the name of the first electromagnetic and noise sensitive point, and the names of ecologically sensitive areas such as nature reserves, scenic spots and drinking water source protection areas along the first line (first geographic information) during the construction drawing stage of this transmission line, imports them into the map software, and names them as the XXX project construction drawing path.

[0083] Secondly, the construction unit collects the coordinates of the second route, the names of the second electromagnetic and noise sensitive points, and the names of the ecologically sensitive areas (second geographic information) of nature reserves, scenic spots and drinking water source protection areas along the second route during the environmental impact assessment stage of the transmission line. It then imports this information into the map software and names it the "XXX Project Environmental Impact Assessment Route".

[0084] The program for judging major changes to transmission lines is initiated. The software will then determine whether there have been major changes to the transmission line route plan in the construction drawings based on the pre-set judgment conditions for major changes to transmission lines.

[0085] 1. If there are no major changes to the transmission line route or the route change does not reach the warning threshold, the route plan is approved and the system indicates that the route plan is feasible.

[0086] II. If the change in the transmission line route has reached the warning standard for a major change, that is, when comparing the construction drawing stage plan with the environmental impact assessment plan, the changes in the construction drawing stage plan compared to the environmental impact assessment plan have met the following conditions:

[0087] 1. The path length during the construction drawing stage increases by more than 25% to 30% compared to the path length in the environmental impact assessment.

[0088] 2. The cumulative length of the lateral displacement of the construction drawing route exceeding 500 meters exceeds 25% to 30% of the length of the environmental impact assessment route plan.

[0089] 3. Due to changes in the construction drawing route, the number of newly added electromagnetic and acoustic environmentally sensitive targets exceeds 25% to 30% of the number of environmental impact assessment route options.

[0090] If a warning is issued regarding the construction drawing route plan, indicating that a major change is imminent, the construction unit should provide feedback to the design unit. The design unit should then optimize and adjust the route plan during the construction drawing design phase, bringing it within the warning line to prevent major changes to the final construction route plan.

[0091] If the change in the transmission line route meets the criteria for a significant change, that is, a comparison between the construction drawing stage plan and the environmental impact assessment plan shows that the changes in the construction drawing stage plan compared to the environmental impact assessment plan have met the following conditions:

[0092] 1. The path length in the construction drawing stage increased by more than 30% compared to the path length in the environmental impact assessment.

[0093] 2. The cumulative length of the lateral displacement of the construction drawing exceeding 500 meters exceeds 30% of the length of the environmental impact assessment route plan.

[0094] 3. Due to changes in the construction drawing route, the number of newly added electromagnetic and acoustic environmentally sensitive targets exceeded 30% of the number of environmental impact assessment route options.

[0095] 4. Due to changes in the construction drawing route plan, the route enters new ecologically sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas.

[0096] If a warning is issued regarding the construction drawing route, indicating a significant change has occurred, the construction unit should report the results to the design unit. The design unit should then optimize the route during the construction drawing design phase, conducting a comprehensive assessment with the construction unit from technical, environmental, economic, and constraining factors to determine the final construction route. If the optimized route no longer constitutes a significant change, the construction unit should proceed with construction work based on the optimized construction drawings. If the adjusted route still constitutes a significant change, but a comprehensive assessment from technical, environmental, economic, and constraining factors deems the proposed solution more reasonable, the construction unit should simultaneously initiate the environmental impact assessment (EIA) preparation process based on the optimized route in the construction drawings to prevent issues during the acceptance process.

[0097] This invention enables automatic judgment of major changes to transmission lines, replacing manual measurement and judgment. It achieves high-precision, automated judgment, reducing the possibility of misjudgments caused by human error. This saves project investment and shortens project completion time. By intervening early in the judgment of major changes, this invention prevents and reduces the occurrence of major changes in transmission line projects, enabling construction units to optimize line routes, save project investment, and shorten project acceptance cycles. Furthermore, if a major change to the line route occurs, the invention allows for simultaneous environmental impact assessment (EIA) work during the construction drawing stage, based on the final construction route, without affecting subsequent environmental protection acceptance upon project completion or the commencement of second-phase project work.

[0098] like Figure 3 As shown, an embodiment of the present invention provides a device 30 for determining the degree of variation in a power transmission line project, comprising:

[0099] Module 31 is used to acquire the first geographic information of the transmission line project and the second geographic information of the environmental impact assessment of the transmission line project.

[0100] Processing module 32 is used to determine the change information between the first geographic information and the second geographic information based on the first geographic information and the second geographic information; and to determine the degree of change of the power transmission line project based on the change information.

[0101] Optionally, obtaining the first geographical information of the power transmission line project includes:

[0102] Obtain the coordinates of the first path, the name of the first electromagnetic and noise sensitive point, and the names of the ecologically sensitive areas along the first line, including nature reserves, scenic spots, and drinking water source protection areas, during the transmission line construction drawing stage of the transmission line project.

[0103] Optionally, obtaining the second geographic information for the environmental impact assessment of the transmission line project includes:

[0104] Obtain the coordinates of the second path, the name of the second electromagnetic and noise sensitive point, and the names of the ecologically sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the second line in the environmental impact assessment stage of the power transmission line project.

[0105] Optionally, determining the change information between the first geographic information and the second geographic information based on the first geographic information and the second geographic information includes:

[0106] The first variation in path length during the construction drawing stage compared to the environmental impact assessment stage is determined based on the first path coordinates and the second path coordinates.

[0107] The second variation range is determined based on the first path coordinates and the second path coordinates, which shows the cumulative length of the lateral displacement of the line in the construction drawing stage exceeding the set value compared to the environmental impact assessment stage.

[0108] Based on the first and second electromagnetic and noise sensitive point names, determine the third change range of the electromagnetic and acoustic environment sensitive targets added in the construction drawing stage compared to the environmental impact assessment stage.

[0109] Based on the names of the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the first route and the names of the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the second route, the fourth change in the ecologically sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the route is determined in the construction drawing stage compared to the environmental impact assessment stage.

[0110] The change information is determined based on the relationship between the first change range and the first set interval, the second change range and the second set interval, the third change range and the third set interval, and the fourth change situation and the fourth set situation.

[0111] Optionally, determining the change information based on the relationship between the first change magnitude and the first set interval, the second change magnitude and the second set interval, the third change magnitude and the third set interval, and the fourth change condition and the fourth set condition includes:

[0112] If the first change exceeds the first set range, the second change exceeds the second set range, the third change exceeds the third set range, or the fourth change meets any of the conditions of the fourth set condition, the change information is determined to be a major change.

[0113] If any one of the following conditions is met: the first change range meets the first set range, the second change range meets the second set range, or the third change range meets the third set range, the change information is determined to be a major change warning.

[0114] If the three conditions are met—the first change range being less than the first set interval, the second change range being less than the second set interval, and the third change range being less than the third set interval—the change information is determined to be an allowed change.

[0115] Optionally, the first change range is the percentage increase in path length during the construction drawing stage compared to the environmental impact assessment stage relative to the total path length during the environmental impact assessment stage.

[0116] The second variation range is the percentage of the cumulative length of the lateral displacement of the route in the construction drawing stage exceeding the set value compared to the environmental impact assessment stage, relative to the total path length in the environmental impact assessment stage.

[0117] The third variation range is the percentage of electromagnetic and acoustic environmental sensitive targets added in the construction drawing stage compared to the environmental impact assessment stage, relative to the total number of electromagnetic and acoustic environmental sensitive targets in the environmental impact assessment stage.

[0118] The fourth change is whether there are any newly added ecologically sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the route during the construction drawing stage compared to the environmental impact assessment stage.

[0119] Optionally, determining the degree of change in the transmission line project based on the change information includes:

[0120] Based on the change information, the degree of change in the transmission line project is determined as a major change, a major change warning, or a permissible change.
