Description

Technical Field

[0001] The present application relates to the field of electrical engineering, and in particular, to a method and device for determining a cable path, and an electronic device. Background Art

[0002] In a photovoltaic power station, all equipment in the photovoltaic plant (strings, combiner boxes, box-type transformers) need to be connected by cables. Cables are generally laid underground by trenching or trough-type bridges. Different cable routing paths have a great impact on the construction cost of the power station and the convenience of construction and operation and maintenance. Therefore, the routing path design of low-voltage cables is crucial.

[0003] Currently, optimization algorithms based on the economic cost model of low-voltage paths exist in this field. These optimization designs are based on a single variable, economic cost. However, these path optimization methods based on the economic cost model of low-voltage cables fail to comprehensively consider the convenience of on-site construction and subsequent operation and maintenance. The optimization results often pose significant challenges on-site, potentially leading to increased on-site construction processes, increased waste, and longer construction cycles.

[0004] To address the above-mentioned problems, no effective solutions have been proposed so far.

[0037] Figure 2 is a flow chart of a cable path determination method according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0038] Step S202, determining multiple cable paths in the target area;

[0039] Step S204, determining the economic cost and construction workload of each of the multiple cable paths;

[0040] Step S206 : determining a target cable path from the plurality of cable paths based on economic cost and construction workload.

[0041] Through the above steps, a path optimization model based on the multi-dimensional factors of cost and construction convenience was established. By determining multiple cable paths in the target area; determining the economic cost and construction workload of each cable path in the multiple cable paths; and determining the target cable path from the multiple cable paths based on the economic cost and construction workload, the purpose of constructing a comprehensive multi-variable optimization model was achieved, thereby achieving the technical effect of simultaneously meeting the economic requirements and the construction convenience requirements, and further solving the technical problem that the existing technology does not comprehensively consider the convenience of on-site construction and subsequent operation and maintenance, and may introduce an increase in on-site construction processes.

[0042] In step S202 of the cable path determination method, multiple cable paths are determined in the target area, specifically including the following steps:

[0043] Step S212: obtaining terrain information and equipment information of the target area, wherein the terrain information includes the non-routable area in the target area, and the equipment information includes the coordinates of the strings, combiner boxes, and box-type transformers in the target area;

[0044] Step S214: generating a plurality of cable paths corresponding to the target area based on the terrain information and the equipment information.

[0045] In an embodiment of the present application, a comprehensive multi-variable optimization model is constructed, and the equipment information and terrain information of the target area are input into the optimization model, which can quickly generate a variety of low-voltage path topology structures, wherein the input equipment information includes string coordinates, junction box coordinates and box transformer coordinates, and the terrain area of the target area includes non-routable areas.

[0046] Specifically, taking a single array of a string mountain power station as an example, assuming that the array equipment includes: 1 box-type transformer and 17 string inverters, when quickly generating multiple low-voltage path topologies based on a low-voltage path optimization algorithm, such as the minimum spanning tree algorithm, multiple low-voltage path sets L1…L n , where the low-voltage path set L1 contains information on the starting and ending point coordinate data of each path. A pair of starting and ending points are combined into a path, and the connection relationship between all starting and ending points forms a tree structure, where the root node of the tree is the location of the box transformer, and the intermediate nodes and leaf nodes of the tree are the locations of the string inverters, or the intersections of the paths, which are called virtual nodes in the example of this application.

[0047] In step S206 of the cable path determination method, a target cable path is determined from multiple cable paths based on economic cost and construction convenience, which specifically includes the following steps:

[0048] Step S222, determining the economic cost and construction workload of each of the plurality of cable paths;

[0049] Step S224: determining an economic cost score corresponding to each cable path based on the economic cost corresponding to each cable path, wherein the higher the economic cost, the greater the economic cost score;

[0050] Step S226, determining a construction workload score corresponding to each cable path based on the construction workload corresponding to each cable path, wherein the greater the construction workload, the higher the construction workload score;

[0051] Step S228, determining a comprehensive evaluation score for each cable route based on the economic cost score and construction workload score corresponding to each cable route;

[0052] Step S230 : According to the comprehensive evaluation scores, a cable path with the lowest comprehensive evaluation score is determined from among the multiple cable paths as a target cable path.

[0053] In steps S222 to S230, the number of path bends is checked and locally adjusted for the generated low-voltage path topology, and the economic cost of the adjusted low-voltage path is evaluated. The economic cost of each adjusted cable path includes at least one of the following: the cable cost, trenching cost, bridge cost, and pile foundation cost corresponding to each cable path. The construction convenience of the adjusted low-voltage path is evaluated, and the key parameters of construction convenience are extracted, that is, the construction engineering quantity includes the following parts: (1) the total length of the low-voltage construction path, wherein the path length affects the construction engineering quantity. The shorter the path, the better. The shorter the path, the smaller the construction engineering quantity and the trenching / bridge laying engineering quantity; (2) the number of bends in the low-voltage construction path, wherein the fewer the number of bends in the construction path, the better. The more bends, the more times the bridge is cut and spliced, and the more construction waste is generated. Similarly, in trenching scenarios, more bends will make excavator operations more difficult. (3) The number of branches in the low-voltage construction path. Similarly, the fewer branches in the construction path, the better. More branches will increase the workload of the bridge or trenching. By calculating the economic cost score and the construction workload score, a comprehensive evaluation score is obtained. Based on the comprehensive evaluation score, the cable path with the lowest comprehensive evaluation score is determined from multiple cable paths as the target cable path.

[0054] In step S228, a comprehensive evaluation score for each cable route is determined based on the economic cost score and construction workload score corresponding to each cable route. This score is obtained by: receiving a construction impact factor selected by the target object; and determining a comprehensive evaluation score based on the construction impact factor, the economic cost score, and the construction workload score. The comprehensive evaluation score is equal to the difference between the economic cost score multiplied by the construction impact factor and the construction workload score multiplied by a preset value and the construction impact factor. The preset value is a number greater than zero, for example, 1.

[0055] Specifically, the calculation formula for the comprehensive evaluation score is as follows:

[0056] O i =E i ×f+(X i +Y i +Z i )×(1-f)

[0057] Among them, O i It represents the comprehensive evaluation score, f represents the construction impact factor, the default value is 0.8, and it can be flexibly adjusted according to the project situation. i represents the economic cost score, X i +Y i +Z i represents the construction quantity score, X i 、Y i 、Z i Respectively represent the subcategory quantities of construction quantities.

[0058] In the above step S224, the economic cost score corresponding to each cable path is determined based on the economic cost corresponding to each cable path, which specifically includes the following steps:

[0059] Step S302, determining the maximum economic cost and the minimum economic cost from the economic costs corresponding to the various cable paths;

[0060] Step S304, determining the cost difference between the maximum economic cost and the minimum economic cost;

[0061] Step S306: Determine the economic cost score corresponding to each cable path based on the economic cost and cost difference corresponding to each cable path, wherein the economic cost score corresponding to each cable path is equal to the ratio of the economic cost of each cable path minus the minimum economic cost to the cost difference.

[0062] Figures 3a to 3d The schematic diagram of the scheme corresponding to four low-voltage paths is shown. Specifically, in steps S302 to S304, the specific calculation method of the economic cost score corresponding to each cable path is described as follows:

[0063] Step 1: Take out Figures 3a to 3d For any of the low-voltage path sets L1 in any scheme, take out each path from the root node, calculate the length of the path, the cable selection, and the bridge selection, and then calculate the cost of the path based on the unit price of the cable and bridge. The paths that have completed the calculation are removed from the L1 set, and the cycle is repeated until all L1 is taken. The sum of the costs of all paths in L1 is recorded as e1.

[0064] Step 2: Loop out the multiple low-pressure paths generated in the first step and calculate the economic cost of the low-pressure path for each solution, which are recorded as: e1…e n ;

[0065] Step 3: Calculate the economic cost score of each option according to the following formula:

[0066]

[0067] Among them, E i represents the economic cost score, e min represents the minimum value of the sum of the economic costs of the cable paths in all options, x max It represents the maximum value of the sum of the economic costs of the cable paths in all options.

[0068] In the above step S226, the construction work quantity score corresponding to each cable path is determined based on the construction work quantity corresponding to each cable path, which specifically includes the following steps:

[0069] Step S402: determining multiple sub-category quantities of the construction quantity corresponding to each cable path, wherein the sub-category quantities include at least one of the following: the total length of the cable path, the total number of branches of the cable path, and the total number of bends in the cable path;

[0070] Step S404: determining a target subcategory engineering quantity score corresponding to each cable path based on the target subcategory engineering quantity corresponding to each cable path, wherein the target subcategory engineering quantity is any one of multiple subcategory engineering quantities;

[0071] Step S406: Determine the construction quantity score corresponding to the cable path based on the quantity scores of each target subcategory corresponding to the cable path, wherein the construction quantity score of the cable path is equal to the sum of the quantity scores of each target subcategory.

[0072] In steps S402 to S406, the construction difficulty corresponding to each cable route needs to be analyzed. The construction difficulty is expressed by the construction work quantity. The construction work quantity includes multiple sub-categories of work quantities, specifically including the following parts:

[0073] (1) Total length of the cable path

[0074] Step 1: Take out Figures 3a to 3d For any of the low-voltage path sets L1 in the solution, starting from the root node, traverse each path in breadth-first order and calculate the length of the path. The sum of the lengths of all paths in L1 is recorded as the total actual path length of the solution, which is recorded as x1.

[0075] Step 2: Loop out each low-pressure path solution and calculate the low-pressure path length of each solution, which are recorded as: x1…x n , and then calculate the construction convenience coefficient 1 according to the following formula:

[0076]

[0077] Among them, X i Indicates the construction work quantity corresponding to the total length of the cable path, x min Indicates the minimum value of the total cable path length, x max Indicates the maximum value of the total cable path length.

[0078] (2) Total number of branches in the cable path

[0079] Step 1: Take out Figures 3a to 3d The low-voltage path set L1 of any scheme starts from the root node and traverses each node in breadth-first order to determine whether there is a child node. If not, do not process it. If there is a child node, count the number of its child nodes n1, and the number of branches of the node m1 = n1 2 (Here n1 2 It is used to reflect that the more branches there are, the greater the construction difficulty is). Then, each child node is traversed and the number of branches of each child node is counted until all nodes are calculated. The sum of the branch coefficients of all nodes in L1 is recorded as the total number of branches of the scheme, which is recorded as y1.

[0080] Step 2: Loop out each low-pressure path solution and calculate the total number of low-pressure path branches for each solution, which are recorded as: y1…y n , and then calculate the construction convenience coefficient 2 according to the following formula:

[0081]

[0082] Among them, Y i Indicates the construction work quantity corresponding to the total number of branches of the calculated cable path, y min Indicates the minimum value among the total number of cable path branches, y max Indicates the maximum value among the total number of cable path branches.

[0083] (3) The total number of bends in the cable path

[0084] Step 1: Take out Figures 3a to 3d The low-voltage path set L1 of any scheme starts from the root node and traverses each path i1 according to the breadth-first order to determine whether there is a directly connected path. If not, do not process it. If so, take out all the paths i1 directly connected to it. 1_neighbor .

[0085] Step 2: Take out i 1_neighbor There is a path j1 in the path i1, and the paths j1 and i1 have three vertices (a, b, c). Use the vector to calculate the angle θ between j1 and i1, and judge whether θ is greater than the preset angle value. The preset angle value can be set according to experience, such as 10°. If θ is greater than the preset angle value, the number of bends is recorded as 1, otherwise the number of bends is recorded as 0. Loop through i 1_neighbor For each path in, calculate each path j i The number of bends formed with i1.

[0086] Step 3: Take out i 1_neighbor A path j1 in the L1 path is traversed downward in a loop according to the Step 1 method until all L1 paths are processed. The sum of the number of bends in all paths is recorded as the total number of path bends in the solution, which is recorded as z1.

[0087] like Figure 4 The diagram below shows the description vector calculation method. According to the input information, the path i1, j1 has three vertices a(x1, y1), b(x2, y2), and c(x3, y3). The calculation formula is as follows:

[0088] ba vector: (x2-x1, y2-y1), bc vector: (x3-x2, y3-y2),

[0089] in:

[0090]

[0091]

[0092]

[0093]

[0094] Step 4: Loop out each low-pressure path solution and calculate the total number of path bends for each solution according to the above steps, which are recorded as: z1…z n , and then calculate the construction convenience coefficient 3 according to the following formula:

[0095]

[0096] Among them, Z i Indicates the construction workload corresponding to the total number of bends in the cable path, z min Indicates the minimum value of the total number of bends in the cable path, z max Indicates the maximum number of bends in the cable path.

[0097] In the above step S404, the target sub-category engineering quantity score corresponding to each cable path is determined based on the target sub-category engineering quantity corresponding to each cable path, which specifically includes the following steps:

[0098] Step S502, determining the maximum engineering quantity and the minimum engineering quantity from the target sub-category engineering quantities corresponding to each cable path;

[0099] Step S504, determining the engineering quantity difference between the maximum engineering quantity and the minimum engineering quantity;

[0100] Step S506: Determine the target subcategory engineering quantity score corresponding to each cable path based on the target subcategory engineering quantity and engineering quantity difference corresponding to each cable path, wherein the target subcategory engineering quantity score corresponding to each cable path is equal to the ratio of the target subcategory engineering quantity of each cable path minus the minimum engineering quantity to the engineering quantity difference.

[0101] The above steps S502 to S506 correspond to X i 、Y i 、Z i The calculation formula, that is, the calculation formula for each sub-category of construction project quantity, will not be repeated here.

[0102] In the above cable path determination method, the minimum value of the comprehensive evaluation score among the various schemes is found, that is, Omin is found, and the cable path corresponding to the minimum value of the comprehensive evaluation score is used as the target cable path. Figures 3a to 3d The economic cost score of the solution in the experiment is calculated by inputting the experimental test data as follows:

[0103] e1=596528, e2=620282, e3=195193, e4=176132, E1=1, E2=0.947, E3=0.043, E4=0

[0104] The calculation results of the construction quantity rating are as follows:

[0105] x1=1084, x2=851, x3=852, x4=904, X1=1, X2=0, X3=0.004, X4=0.227

[0106] y1=42, y2=24, y3=24, y4=28, Y1=1, Y2=0, Y3=0, Y4=0.222

[0107] z1=36, z2=19, z3=19, z4=17, Z1=1, Z2=0.105, Z3=0.105, Z4=0

[0108] The default value of the construction impact factor f is set to 0.8, and the comprehensive evaluation score calculation results are as follows:

[0109] O1=1×0.8+(1+1+1)×0.2=1.4,

[0110] O2=0.947×0.8+(0+0+0.105)×0.2=0.7786,

[0111] O3=0.043×0.8+(0.004+0+0.105)×0.2=0.0562,

[0112] O4=0×0.8+(0.227+0.222+0)×0.2=0.0898

[0113] According to the above case, it can be seen that only the economic cost of Plan 4 is the lowest. After comprehensively considering the economic cost and construction workload, Plan 3 has the lowest comprehensive score. Therefore, the best plan is: Plan 3.

[0114] This embodiment of the application integrates multiple dimensions of construction convenience to create an optimized solution that better matches actual site conditions, avoiding the unconstructability caused by optimizing for a single economic metric. By performing a comprehensive, multivariable computer optimization of the low-voltage cable routing for a photovoltaic power station, the resulting solution meets both economic and construction convenience requirements.
