Description

Technical Field

[0001] This invention relates to the field of integrated energy system planning, and more particularly to a method, system, and medium for determining the number of wind turbines to be installed on a site. Background Technology

[0002] Wind energy is an inexhaustible and clean renewable energy source. Depending on the needs, wind energy can be converted into other forms of energy, such as mechanical energy, electrical energy, and thermal energy. As reserves of mineral resources such as coal, oil, and natural gas are dwindling, wind energy will play an increasingly important role in future energy development and utilization. However, the installation locations for wind turbines have not been accurately analyzed; simply calculating the number of turbines based on general methods leads to wasted funds. Therefore, a suitable method needs to be proposed to solve this problem.

[0003] Given the irrationality of existing calculations for the number of wind turbines to be installed, a method for the layout and calculation of wind turbines for regions with different shapes is needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for determining the number of wind turbines to be installed on a site. This method uses graphics of different shapes to simulate the actual area, thereby simulating the number of wind turbines. This method can solve the problem of inaccurate calculation of the number of wind turbines under conventional methods, and helps to better calculate the number of wind turbines.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A method for determining the number of wind turbines to be installed on a site includes:

[0007] Step 1: Obtain the safe footprint and diameter of the single wind turbine to be installed based on the height of the wind turbine; and obtain the land boundary line file of the site where the wind turbine is to be installed; wherein, the land boundary line file includes the boundary line graphic and the boundary line coordinates; determine the shape of the boundary line graphic based on the boundary line graphic, and obtain the side length / radius length;

[0008] Step 2: Based on the boundary line diagram, if the boundary line diagram is not a rectangle, triangle, or circle, divide the site boundary diagram into combinations of rectangles, triangles, or circles; if the boundary line diagram is a rectangle, triangle, or circle, determine whether the side length / diameter of the boundary line diagram is divisible by the safe diameter of a single wind turbine; if it is divisible, calculate the number of wind turbines that can be installed based on the divisible data; if it is not divisible, consider redundancy based on the divisible data, and increase the number of wind turbines that can be installed according to the remainder after division.

[0009] Furthermore, step two specifically includes:

[0010] Square: When the boundary line obtained in step one is a square, determine whether the side length and the safe diameter of a single wind turbine satisfy condition one:

[0011]

[0012] In the formula, [] represents the rounding symbol, L represents the side length of the square, and D represents the diameter of the area occupied by the wind turbine.

[0013] If so, continue the assessment. Is it divisible? If it is divisible, it is assumed that the wind turbines can be arranged neatly, and the number of wind turbines that can be installed is:

[0014]

[0015] If it is not divisible, there is redundancy, and At that time, the number of wind turbines that can be installed is:

[0016]

[0017] If it is not divisible and contains redundancy, determine whether condition two is satisfied:

[0018]

[0019] If the requirements are met, the number of wind turbines that can be installed is:

[0020]

[0021] Otherwise, determine whether condition three is met:

[0022]

[0023] The number of wind turbines that can be installed is:

[0024]

[0025] Rectangle: When the bounding line obtained in step one is a rectangle, determine whether the length and width are divisible by the safe diameter of a single wind turbine. If so, the number of wind turbines that can be installed is:

[0026]

[0027] Where Mw is the number of wind turbines, A is the length of the rectangle, B is the width of the rectangle, and D is the diameter of the area occupied by the wind turbines.

[0028] If it is not divisible, and condition four is met:

[0029]

[0030] The number of wind turbines that can be installed is:

[0031]

[0032] If the length and width are not divisible by the diameter of the wind turbine's footprint, and condition five is satisfied:

[0033]

[0034] The number of wind turbines that can be installed is:

[0035]

[0036] If the length and width are not divisible by the diameter of the wind turbine's footprint, and condition six is ​​satisfied:

[0037]

[0038] The number of wind turbines that can be installed is:

[0039]

[0040] If the length and width are not divisible by the diameter of the wind turbine's footprint, and condition seven is satisfied:

[0041]

[0042] The number of wind turbines that can be installed is:

[0043]

[0044] Circular: When the boundary line obtained in step one is circular, determine whether the diameter of the boundary line is divisible by the safe diameter of a single wind turbine. If it is divisible, the number of wind turbines that can be installed is:

[0045]

[0046] Where n represents the number of layers arranged radiating outwards from the center point of the circular boundary line of the site. C represents the radius of the boundary line diagram, and R represents the radius of the area occupied by the wind turbine.

[0047] If it is not divisible and condition eight is satisfied:

[0048]

[0049] The number of wind turbines that can be installed is:

[0050]

[0051] Equilateral triangle: When the boundary line obtained in step one forms an equilateral triangle, the number of wind turbines that can be installed is:

[0052]

[0053] Where L represents the side length of the triangle, and n represents the number of rows.

[0054] Isosceles right triangle: When the boundary line obtained in step one is an isosceles right triangle, the number of wind turbines that can be installed is:

[0055]

[0056] Where L represents the length of the right-angled side, and n represents the number of layers.

[0057] Other: When the boundary line graphic obtained in step one does not belong to any of the above graphics, the site boundary graphic is divided into a combination of the previous graphics, and then the number of wind turbines that can be installed is calculated using the aforementioned method on the divided graphics.

[0058] Preferably, in step one, a safe footprint radius of 1.5 times the height of the wind turbine is used to obtain the diameter and footprint of a single wind turbine.

[0059] Furthermore, the boundary line graphic is selected from one of the following shapes: square, rectangle, circle, and triangle.

[0060] Furthermore, when the area is determined to be a square and is divisible or satisfies condition one, individual wind turbines are arranged from the outside to the inside along the boundary line of the range, based on the calculated number of wind turbines.

[0061] When the shape is determined to be square and condition 2 is met, based on the calculated number of wind turbines, first arrange the wind turbines along the edge of the range line, and then add a wind turbine in the middle of the arranged wind turbines.

[0062] When the shape is determined to be square and condition three is met, based on the calculated number of wind turbines, first arrange the wind turbines along the boundary line, and then add wind turbines intersectingly in the empty spaces inside the arranged wind turbines.

[0063] Furthermore, when the shape is determined to be rectangular and can be divided evenly or satisfy condition four, wind turbines are arranged along the length and width of the rectangular range line according to the calculated number of wind turbines.

[0064] When the shape is determined to be rectangular and condition five is met, based on the calculated number of wind turbines, wind turbines are first arranged simultaneously along the length and width of the rectangular range line. At this time, there is a gap in the length direction, and the wind turbines are arranged in a crisscross pattern along the width direction in the gap.

[0065] When the shape is determined to be rectangular and condition six is ​​met, based on the number of wind turbines calculated, wind turbines are first arranged simultaneously along the length and width of the rectangular range line. At this time, there is a gap in the width direction, and the wind turbines are arranged in a crisscross pattern along the length direction in the gap.

[0066] When the shape is determined to be rectangular and condition seven is met, based on the calculated number of wind turbines, wind turbines are first arranged simultaneously along the length and width of the rectangular boundary line. At this time, there is space in both the length and width directions, and in the space, they are arranged in a crisscross pattern along both the length and width directions.

[0067] Furthermore, when the circle is determined to be circular and divisible, based on the calculated number of wind turbines, the center point of the circle of the site boundary line is taken as the center of a wind turbine, and the wind turbines are arranged outward from the center point.

[0068] When the shape is determined to be circular and condition eight is met, based on the calculated number of wind turbines, the center point of the circle of the site boundary line is used as the center of a wind turbine, and wind turbines are arranged outward from the center point; if there is a margin, an additional wind turbine is added between every two wind turbines in the outermost layer.

[0069] Furthermore, when the shape is determined to be an equilateral triangle, based on the calculated number of wind turbines, one corner is selected to determine the position of the first wind turbine, and then the remaining wind turbines are arranged in sequence.

[0070] Furthermore, when the triangle is determined to be an isosceles right triangle, the position of the first wind turbine is determined by selecting an angle based on the calculated number of wind turbines, and then the remaining wind turbines are arranged in sequence.

[0071] A second aspect of the invention discloses a system for determining the number of wind turbines to be installed on a site, comprising:

[0072] The land use boundary line and single wind turbine footprint module are used to obtain the safe footprint area and diameter of the single wind turbine to be installed based on the height of the wind turbine; and to obtain the land use boundary line file of the site where the wind turbine is to be installed; and to determine the shape of the boundary line graphic based on the boundary line graphic, and obtain the side length / radius length.

[0073] The segmentation module is used to segment the site area graphic into a combination of rectangles, triangles, or circles when the boundary line graphic does not belong to one of the three categories: rectangle, triangle, or circle.

[0074] The calculation module is used to calculate the number of wind turbines that can be installed within the current land use boundary line based on the shape of the defined boundary line graphic.

[0075] The layout module is used to maximize the number of wind turbines to be arranged based on the shape of the defined boundary line graphic and the number of wind turbines that can be installed.

[0076] A third aspect of the present invention is to provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the calculation method for determining the number of wind turbines to be installed on a site as described in the foregoing scheme.

[0077] A fourth aspect of the present invention provides an electronic device comprising a memory and a processor. The memory stores a computer program, and the processor is communicatively connected to the memory. When the computer program is invoked, the calculation method for determining the number of wind turbines to be installed on a site, as described in the foregoing scheme, is executed.

[0078] Compared with the prior art, the beneficial effects of the present invention are:

[0079] The method described in this invention is very effective in calculating the number of wind turbines to be installed at a site. It can maximize the number and effectiveness of wind turbines installed without affecting the lives of surrounding residents. Attached Figure Description

[0096] To make the objectives, technical solutions, beneficial effects, and significant advancements of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings provided in the examples of the present invention. Obviously, all the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0097] It should be noted that the wind turbine installation site involved in this invention is located in a flat area. Furthermore, the floor area of ​​the wind turbine mentioned herein is determined based on the height of the wind turbine, taking into account the foundation area and ensuring that the rotating blades do not interfere with each other. Moreover, this invention primarily relates to determining the maximum number of wind turbines that can be installed on a given site.

[0098] like Figure 1 As shown, a method for determining the number of wind turbines to be installed on a site includes:

[0099] Step 1: Determine the region;

[0100] S11: Determine the footprint of the single wind turbine to be installed.

[0101] When calculating the footprint of a wind turbine, considering that the footprint is mainly determined by the height of the wind turbine, the following calculation is performed:

[0102] A safe length for the footprint radius is selected as 1.5 times the height of the wind turbine. The footprint area of ​​a single wind turbine is calculated as follows:

[0103] Sw = π * (1.5 * h) 2 (Equation 1)

[0104] In the formula, Sw is the footprint of a wind turbine, and h is the height of the wind turbine. The footprint obtained here is circular, so the diameter of the footprint of a single wind turbine can be obtained according to Equation 2.

[0105] D = 1.5h * 2 = 3h (Equation 2)

[0106] Where D represents the diameter of the footprint of a single wind turbine, and h represents the height of the wind turbine.

[0107] As shown in the attached diagram, the footprint of the wind turbine is represented by circles. The small gap between adjacent circles in the diagram is only for illustrative purposes to distinguish between them; in actual calculations, no gap is set between adjacent wind turbine footprints.

[0108] S12: The user selects a site within the venue for setting up multiple wind turbines and obtains the land use boundary line file of the site; wherein, the land use boundary line file includes a boundary line graphic and boundary line coordinates; the boundary line graphic is a graphic formed by the bounding boundary lines, such as when the boundary line graphic is a square, the boundary lines are the square frame lines, and the bounding boundary line graphic is a square.

[0109] The shape of the boundary line is manually determined based on the obtained boundary line graphic. If the boundary line graphic is square, the side length L of the square boundary line is obtained using the distance measurement tool in AutoCAD software, and then step S is executed. 正方形 If the shape is rectangular, use the distance measurement tool in AutoCAD to obtain the length and width of the rectangular boundary lines, and then proceed to step S. 长方形 If the shape is circular, use the distance measurement tool in AutoCAD to obtain the radius, and then proceed to step S. 圆形 If the shape is triangular, use the distance measurement tool in AutoCAD to obtain the side lengths, and then proceed to step S. 三角形 If none of the above shapes are met, proceed to step S. 其他 .

[0110] Step 2: Calculate the required number of fans based on the area.

[0111] 1. Square S 正方形 :

[0112] When step S12 determines that the selected site boundary line is a square, determine whether the side length value obtained in step S12 and the site diameter value obtained in step S11 satisfy condition one:

[0113]

[0114] In the formula, [] represents the rounding symbol, L represents the side length of the square, and D represents the diameter of the area occupied by the wind turbine.

[0115] If so, continue the assessment. Is it divisible? If so, the side length of the square is an integer multiple of the diameter of the area occupied by the wind turbine. Assuming the wind turbines can be arranged neatly, the number of wind turbines that can be installed is:

[0116]

[0117] Where Mw represents the number of wind turbines.

[0118] With a determined number of wind turbines, arranging them inwards from the square's boundary line, along the square's side lines, can achieve the following: Figure 2 The 2x2 arrangement shown.

[0119] Thus obtain such Figure 2 The diagram shows a 2x2 arrangement of wind turbines.

[0120] If it is not divisible and there is redundancy, and At that time, the number of wind turbines that can be installed is:

[0121]

[0122] The values ​​obtained in this way and Figure 2 As shown, except that there is empty space inside the square frame area.

[0123] If the result is not divisible and contains redundancy, continue to check if condition two is met:

[0124]

[0125] Number of wind turbines that can be installed:

[0126]

[0127] Using step S 正方形 -1 First, arrange the wind turbines along the sides of the square, then add another wind turbine in the middle of the arranged turbines to maximize resource utilization. The arrangement is as follows: Figure 3 As shown.

[0128] Otherwise, determine whether condition three is met:

[0129]

[0130] The number of wind turbines that can be installed is:

[0131]

[0132] Arrangement as Figure 4 As shown, the wind turbines are first arranged along the square boundary line. After the arrangement is completed, the remaining space is filled by cross-compensation, thereby maximizing the number of wind turbines installed.

[0133] 2. Rectangle S 长方形 :

[0134] When step S12 determines that the selected site boundary line is rectangular, it checks whether the length and width values ​​obtained in step S12 are divisible by the diameter of the wind turbine's footprint. If they are divisible, the wind turbines are considered to be able to be arranged neatly, and the number of wind turbines that can be installed is:

[0135]

[0136] Where Mw is the number of wind turbines, A is the length of the rectangle, B is the width of the rectangle, and D is the diameter of the area occupied by the wind turbines.

[0137] Based on the number of wind turbines obtained, the turbines are arranged directly along the length and width of the rectangular area to achieve the following layout: Figure 5 The arrangement shown.

[0138] If the length and width are not divisible by the diameter of the wind turbine's footprint, and both have redundancy, and condition four is satisfied:

[0139]

[0140] The number of wind turbines that can be installed is:

[0141]

[0142] [] represents the integer part number.

[0143] Based on the number of wind turbines obtained, the turbines are arranged along the length and width of the rectangular area simultaneously to achieve the desired layout. Figure 6 The arrangement shown.

[0144] If the length and width are not divisible by the diameter of the wind turbine's footprint, and condition five is satisfied:

[0145]

[0146] The number of wind turbines that can be installed is:

[0147]

[0148] Based on the number of wind turbines obtained, the turbines are initially arranged along both the length and width of the rectangle. Since there is excessive space along the length of the rectangle, they are then arranged in a crisscross pattern along the width of the rectangle to achieve the desired arrangement. Figure 7 The arrangement shown.

[0149] If the length and width are not divisible by the diameter of the wind turbine's footprint, resulting in redundancy, and condition six is ​​satisfied:

[0150]

[0151] The number of wind turbines that can be installed is:

[0152]

[0153] Based on the number of wind turbines obtained, the turbines are initially arranged along both the length and width of the rectangle. Since there is excessive space in the width direction, they are then arranged in a staggered pattern along the length of the rectangle in the remaining spaces, thus achieving the desired arrangement. Figure 8 The arrangement shown.

[0154] If the length and width are not divisible by the diameter of the wind turbine's footprint, and condition seven is satisfied:

[0155]

[0156] The number of wind turbines that can be installed is:

[0157]

[0158] Based on the number of wind turbines obtained, the turbines are initially arranged along the length and width of the rectangle. Since there is excess space in both the length and width, they are then interleaved along both the length and width of the rectangle in these spaces. Finally, a wind turbine is added at the last intersection point to achieve the desired arrangement. Figure 9 The arrangement shown.

[0159] 3. Circular S 圆形 :

[0160] When step S12 determines that the selected site boundary line is circular, it checks whether the diameter obtained in step S12 is divisible by the diameter of the wind turbine's footprint. If it is divisible, the wind turbines are considered to be able to be arranged neatly, and the number of wind turbines that can be installed is:

[0161]

[0162] in,

[0163] In the formula, n represents the number of layers that spread outward from the center point of the circle of the site boundary line, C represents the radius of the circle, and R represents the radius of the area occupied by the wind turbine.

[0164] Arrangement methods include: such as Figure 10As shown, the center point of the circular boundary line of the site is used as the center of a wind turbine. First, place the center of the first black circle (representing the wind turbine's footprint) at the center of the larger circle. Arrange a second layer of circles around this black circle, and repeat this process until the entire interior of the larger circle is filled. For each layer, smaller circles are arranged in a hexagonal close-packed arrangement. The hexagonal close-packed arrangement means arranging the smaller circles into a tightly filled hexagonal grid, which maximizes the use of the circular space, minimizes the distance between the centers, and prevents overlap.

[0165] If the diameter is not divisible by the diameter of the wind turbine's footprint, resulting in redundancy, and condition eight is satisfied:

[0166]

[0167] The number of wind turbines that can be installed is:

[0168]

[0169] in, n represents the number of the outer circles of the black circle located at the center point.

[0170] Using the center point of the circular boundary line of the site as the center of a wind turbine, first place the center of the first black circle (as the footprint of the wind turbine) at the center of the larger circle. Arrange a second layer of circles around this black circle, and repeat this process. Then, begin adding one between the two outermost wind turbines, thus obtaining... Figure 11 The arrangement shown.

[0171] 4. Triangle S 三角形 :

[0172] When S12 in step one determines that the selected site boundary line is a triangle, since the area of ​​each circle is fixed, the number of circles placed depends not only on the shape of the triangle, but also on the area of ​​each circle and the arrangement of the circles.

[0173] When the site boundary line is an equilateral triangle, determine whether the side length of the equilateral triangle obtained in step S12 is divisible by the diameter of the wind turbine's footprint. If it is divisible, it is considered that the wind turbines can be arranged neatly, and the number of wind turbines that can be installed is:

[0174]

[0175] Where L represents the side length of the triangle, and n represents the number of rows.

[0176] To determine the number of wind turbines, first, based on the fact that the side length of the equilateral triangle is the radius of the area occupied by the wind turbine, select an angle to determine the position of the first wind turbine. Then, arrange them sequentially to obtain the total number of wind turbines, thus obtaining the following... Figure 12 The arrangement shown.

[0177] If the side length of an equilateral triangle is not divisible by the diameter of the area occupied by the wind turbine, resulting in redundancy, the number of wind turbines that can be installed is:

[0178]

[0179] Where n represents the number of rows in the permutation.

[0180] The results show that the number of wind turbines calculated using the equilateral triangle method is the same regardless of whether there is redundancy.

[0181] When the site boundary line is an isosceles right triangle, determine whether the length of the right-angled side of the isosceles triangle obtained in step S12 is divisible by the diameter of the area occupied by the wind turbine. If it is divisible, it is considered that the wind turbines can be arranged neatly, and the number of wind turbines that can be installed is:

[0182]

[0183] Where L represents the length of the right-angled side, and n represents the number of layers.

[0184] Based on the number of wind turbines obtained, the location of the first wind turbine is determined by using the side length of the isosceles right triangle as the radius of the area occupied by the wind turbine. Then, the turbines are arranged sequentially along the right-angled sides, with additional turbines added in other locations, thus obtaining the following... Figure 13 The arrangement shown.

[0185] If the length of the right-angled side of an isosceles triangle is not divisible by the diameter of the area occupied by the wind turbine, resulting in redundancy, the number of wind turbines that can be installed is:

[0186]

[0187] Where L represents the length of the right-angled side, and n represents the number of rows.

[0188] The results show that the number of wind turbines calculated using isosceles triangles is the same regardless of whether there is redundancy.

[0189] 5. Other S 其他 :

[0190] When S12 in step one determines that the selected site boundary line graphic is "other", that is, the previous few set graphics cannot be used for approximate calculation, the site boundary line graphic needs to be divided into a combination that is close to the previous graphics. Then, the number of wind turbines is calculated using the previous method on the divided graphics.

[0191] Example 1

[0192] like Figure 14 As shown, two areas in a certain community are to be equipped with wind turbines. The boundary line of area A is a triangle, while the boundary line of area B is another shape. The specific calculation method for area A is as follows:

[0193] Step 1: Select area A as the test object. The two sides of area A are 120m and 123m respectively, and the hypotenuse is 170m.

[0194] Step 2: Select a footprint diameter D of 30m for the wind turbine generator.

[0195] Step 3: Region A is approximately an isosceles right triangle, therefore the calculation method for isosceles right triangles can be used. The approximate leg L of region A is then 120m.

[0196] Calculations show that the length of the right-angled side of the isosceles triangle is not divisible by the diameter of the wind turbine's footprint, indicating redundancy.

[0197] To proceed with the calculations, first calculate the cumulative number.

[0198]

[0199] Then the number of wind turbines was obtained as follows:

[0200]

[0201] Although there is redundancy in the side length during the calculation, the amount of redundancy will not affect the change in the number of wind turbines.

[0202] Step 4: The final number of wind turbines that can be installed is 6.

[0203] Area B is U-shaped (the black square in the diagram represents a house, and this is an area where wind turbines cannot be added). Therefore, in step one, it was determined that this shape does not conform to any of the following: circle, square, rectangle, or triangle. Step S is then executed. 其他 ;

[0204] Step 1: Select area B as the test object. The four side lengths of area B are 81m, 62m, 82m, and 61m, and the side length of the small house in the middle is 30m.

[0205] Step 2: Select a radius of 15m for the footprint of the wind turbine;

[0206] Step 3: After approximating region B, it needs to be divided into three regions: B1, B2, and B3. Region B1 is a rectangle with a length of 60m and a width of 20m; region B2 is a square with a side length of 30m; and region B3 is a rectangle with a length of 60m and a width of 30m. Figure 15 As shown. The following is a calculation of the number of wind turbines:

[0207] Region B1 has width redundancy, because Therefore, the number of wind turbines that can be installed is 0.

[0208] Region B2 has no redundancy; calculations are performed on it.

[0209]

[0210] There is no redundancy, so only one wind turbine can be installed in area B2.

[0211] Region B3 has no redundancy; calculations are performed on it.

[0212]

[0213] Therefore, two wind turbines can be installed in area B3.

[0214] Step 4: Add the three regions together to calculate the final number of wind turbines that can be installed, which is 3.

[0215] Although preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these are within the scope of protection of the present invention.
