According to different needs, wind energy can be converted into other forms of energy, such as mechanical energy, electrical energy, thermal energy, etc. As the storage of mineral resources such as coal, oil, and natural gas is decreasing, wind energy will play an increasingly important role in the development and utilization of energy in the future. However, the installation location of wind turbines has not been accurately analyzed. Only through general calculations to obtain the number of wind turbines will cause a waste of funds. A suitable method needs to be proposed to solve this problem.

[0096] In order to make the purpose, technical solution, beneficial effects and significant progress of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention is clearly and completely described below in conjunction with the drawings provided in the examples of the present invention. Obviously, all the described embodiments are only partial embodiments of the present invention, rather than all embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0097] It should be noted that the wind turbine installation site involved in the present invention is located in a flat area. Moreover, the floor area of ​​the wind turbine involved in the article is determined according to the height of the wind turbine, taking into account the foundation area of ​​the wind turbine and the fact that the blades do not affect each other when rotating. Moreover, the present invention mainly involves determining the maximum number of wind turbines in a site.

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

[0099] Step 1: Region determination;

[0100] S11: Determine the area occupied by a single wind turbine to be installed

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

[0102] Select 1.5 times the height of the wind turbine as the safe length of the footprint radius, and the footprint of a single wind turbine is calculated as follows:

[0103] Sw=π*(1.5*h) 2 (Formula 1)

[0104] Where 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 footprint diameter of a single wind turbine is obtained according to Formula 2.

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

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

[0107] As shown in the attached figure, the area occupied by the wind turbine is represented by a circle. There is a small gap between adjacent circles in the figure, which is only for the purpose of illustration to distinguish two adjacent circles. In actual calculation, no gap is set between the areas occupied by two adjacent wind turbines.

[0108] S12: The user selects a site in the site for setting up a plurality of wind turbines, and obtains a land use boundary line file of the site; wherein the land use boundary line file includes a boundary line figure and a boundary line coordinate; the boundary line figure is a figure formed by the boundary lines, for example, when the boundary line figure is a square, the boundary line is a square frame line, and the boundary line figure formed by the boundary lines is a square;

[0109] The shape of the range line figure is manually determined according to the obtained range line figure. If the shape of the range line figure is a square, the side length L of the square range line is obtained by using the distance measurement tool of the AUTOCAD software, and then step S is executed. 正方形 ; If the shape is a rectangle, use the distance measurement tool of the AUTOCAD software to obtain the length and width of the rectangle range line, and then execute step S 长方形 ; If the shape is a circle, use the distance measurement tool in the AUTOCAD software to obtain the radius, and then execute step S 圆形 ; If the shape is a triangle, use the distance measurement tool in the AUTOCAD software to obtain the side length, and then execute step S 三角形 ; If none of the above shapes meet the requirements, execute step S 其他 .

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

[0111] 1. Square S 正方形 :

[0112] When S12 in step 1 determines that the selected site boundary line figure is a square, it is determined whether the side length value obtained in step S12 and the floor area diameter value obtained in step S11 meet condition 1:

[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 yes, continue to judge Is it divisible? If it is divisible, the side length of the square is an integer multiple of the diameter of the wind turbine. It is assumed that the wind turbines can be arranged neatly. The number of wind turbines that can be installed is:

[0116]

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

[0118] When the number of wind turbines is determined, the wind turbines are arranged from the square range line inward and along the square side line to obtain the following: Figure 2 The 2*2 arrangement shown.

[0119] Thus obtaining Figure 2 The layout diagram of the wind turbines shown is a 2*2 arrangement.

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

[0121]

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

[0123] If it cannot be divided evenly and there is redundancy, continue to determine whether the second situation is met:

[0124]

[0125] The number of wind turbines that can be installed:

[0126]

[0127] Using step S 正方形 -1 First, the wind turbines are arranged along the edges of the square, and then a wind turbine is added in the middle of the arranged wind turbines to maximize resource utilization. The arrangement is as follows: Figure 3 shown.

[0128] Otherwise, determine whether condition 3 is met:

[0129]

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

[0131]

[0132] Arrange as Figure 4 As shown, the wind turbines are first arranged along the range lines of the square, and after the arrangement is completed, the vacant spaces are cross-compensated along the vacant spaces, so that the number of installed wind turbines is maximized.

[0133] 2. Rectangular S 长方形 :

[0134] When the selected site boundary line figure is determined to be a rectangle in step 1 S12, it is determined whether the length and width values ​​obtained in step S12 are divisible by the diameter of the wind turbine footprint. If they are divisible, it is considered that the wind turbines can be arranged neatly, and the number of wind turbines that can be installed is:

[0135]

[0136] Among them, 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 turbine.

[0137] According to the number of wind turbines obtained, the wind turbines are arranged directly along the length and width directions of the rectangular range line during arrangement, so as to obtain the following: Figure 5 Arrangement shown.

[0138] If the length and width are not divisible by the diameter of the wind turbine, there is redundancy and condition 4 is met:

[0139]

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

[0141]

[0142] Among them, [] represents the rounding symbol.

[0143] According to the number of wind turbines obtained, when arranging, the wind turbines are also arranged directly along the length and width directions of the range line of the rectangle at the same time, so as to obtain the following Figure 6 Arrangement shown.

[0144] If the length and width are not divisible by the diameter of the wind turbine, there is redundancy and condition 5 is met:

[0145]

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

[0147]

[0148] According to the number of wind turbines obtained, the wind turbines are first arranged along the length and width of the rectangular range line. At this time, there is too much space in the length of the rectangle, so they are arranged crosswise along the width direction in the spare space, so as to obtain the following: Figure 7 Arrangement shown.

[0149] If the length and width are not divisible by the diameter of the wind turbine, there is redundancy and condition 6 is met:

[0150]

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

[0152]

[0153] According to the number of wind turbines obtained, the wind turbines are first arranged along the length and width directions of the rectangular range line. At this time, there is too much space in the width direction of the rectangle, so they are arranged crosswise along the length direction in the spare space, so as to obtain the following: Figure 8 Arrangement shown.

[0154] If the length and width are not divisible by the diameter of the wind turbine, there is redundancy and condition seven is met:

[0155]

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

[0157]

[0158] According to the number of wind turbines obtained, the wind turbines are first arranged along the length and width of the rectangle. At this time, there is too much space in the length and width of the rectangle, so they are arranged crosswise in the spare space along the length and width, and a wind turbine can be added at the last intersection position, so as to obtain the following: Fig. 9 Arrangement shown.

[0159] 3. Circular S 圆形 :

[0160] When the selected site boundary line figure is determined to be a circle in step 1 S12, it is determined whether the diameter obtained in step S12 is divisible by the diameter of 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:

[0161]

[0162] in,

[0163] Where n represents the number of layers diffused from the circular center point of the site boundary line to the edge line, C represents the radius of the circle, and R represents the radius of the wind turbine.

[0164] Arrangement methods include: Fig.10As shown, the center point of the circle of the site boundary line is used as the center of a wind turbine. First, the center of the first black circle (which occupies the area of ​​the wind turbine) is placed at the center of the large circle. The second layer of circles is arranged around the black circle, and the process is repeated until the entire large circle is filled. When arranging each layer, small circles are placed in a hexagonal close-packed arrangement. Hexagonal close-packed arrangement means arranging small circles into a tightly packed hexagonal grid, which can maximize the use of the circular space, minimize the distance between the centers of the circles, and do not overlap.

[0165] If the diameter is not divisible by the diameter of the wind turbine, there is redundancy and condition eight is met:

[0166]

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

[0168]

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

[0170] Take the center point of the circle of the site boundary line as the center of a wind turbine. First, place the center of the first black circle (as the wind turbine) at the center of the large circle. Arrange the second layer of circles around the black circle and repeat this process. Then start adding one between the two outermost wind turbines to obtain the following: Fig.11 Arrangement shown.

[0171] 4. Triangle S 三角形 :

[0172] When S12 in step 1 determines that the selected site boundary line figure 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 figure is an equilateral triangle, it is determined whether the side length of the equilateral triangle obtained in step S12 is divisible by the diameter of 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:

[0174]

[0175] Among them, L represents the side length of the triangle, n represents the number of rows,

[0176] To obtain the number of wind turbines, first select an angle to determine the position of the first wind turbine based on the side length of the equilateral triangle as the radius of the wind turbine, and then arrange the wind turbines in sequence to obtain the number of wind turbines, so as to obtain Fig.12 Arrangement shown.

[0177] If the side length of the equilateral triangle and the diameter of the wind turbine are not divisible by an integer and there is redundancy, the number of wind turbines that can be installed is:

[0178]

[0179] Among them, n represents the number of rows.

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

[0181] When the site boundary line figure is an isosceles right triangle, it is determined whether the length of the right angle side of the isosceles triangle obtained in step S12 is divisible by the diameter of 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] Among them, L represents the length of the right angle side, n represents the number of arrangement layers,

[0184] According to the number of wind turbines obtained, the position of the first wind turbine is determined based on the side length of the isosceles right triangle as the area radius of the wind turbine, and then arranged along the right angle side in turn, and supplemented in other places, so as to obtain the following: Fig.13 Arrangement shown.

[0185] If the length of the right angle side of the isosceles triangle and the diameter of the wind turbine are not divisible by an integer, there is redundancy, and the number of wind turbines that can be installed is:

[0186]

[0187] Among them, L represents the length of the right angle side, n represents the number of rows,

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

[0189] 5. Other S 其他 :

[0190] When S12 in step 1 determines that the selected site boundary line figure is other, that is, the first few set figures cannot be used for approximate calculation, it is necessary to first segment the site boundary line figure into a combination close to the previous figures, and then use the previous method to calculate the number of wind turbines on the segmented figures.

[0191] Example 1

[0192] like Fig.14 As shown in the figure, there are two areas in a certain community where wind turbines are to be installed. The boundary line graph of area A is a triangle, and the boundary line graph of area B is other graphs. 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 the diameter D of the wind turbine as 30m.

[0195] Step 3: Area A is approximately an isosceles right triangle, so the calculation method of isosceles right triangle can be used for calculation. Then the approximate right-angle side L of Area A is 120m.

[0196] According to calculations, the length of the right angle side of the isosceles triangle and the diameter of the wind turbine are not divisible by an integer and there is redundancy.

[0197] Directly calculate, first calculate the cumulative number

[0198]

[0199] Then the number of wind turbines is

[0200]

[0201] Although there is redundancy in the side length during calculation, the amount of redundancy does 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 in the shape of a "concave" character (the black square in the figure indicates a house and is an area where wind turbines cannot be added). That is, in step 1, it is determined that the shape does not conform to any of the following: circle, square, rectangle, and triangle. Step S is executed. 其他 ;

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

[0205] Step 2: Select the radius of the wind turbine as 15m;

[0206] Step 3: After approximating area B, segment it. First, segment it into three shapes, namely area B1, area B2 and area B3. Area B1 is a rectangle with a length of 60m and a width of 20m, area B2 is a square with a side length of 30m, and area B3 is a rectangle with a length of 60m and a width of 30m. Fig.15 As shown. The number of wind turbines is calculated as follows:

[0207] There is width redundancy in the B1 region due to Then the number of wind turbines that can be installed is 0.

[0208] There is no redundancy in the B2 area, so calculate it

[0209]

[0210] There is no redundancy, so 1 wind turbine can be installed in area B2.

[0211] There is no redundancy in the B3 area, so calculate it

[0212]

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

[0214] Step 4: Add the three areas together and finally get the number of wind turbines that can be installed is 3.
