Description

Technical Field

[0001] This invention belongs to the field of prefabricated substation design technology, specifically, it relates to a portable simulation substation construction device and method suitable for prefabricated substations. Background Technology

[0002] With the rapid development of urban power grids, the construction of substations has entered a fierce stage, but it faces a series of increasingly severe land-related problems, including extremely limited or irregular land availability, difficulties in land acquisition, and high land costs. During the decision-making phase, due to the lack of involvement of professional consulting firms, clients often rely on past experience, frequently leading to unresolved land-related issues during later research phases, resulting in a waste of initial investment in human, financial, and material resources. Furthermore, prefabricated substations primarily rely on design firms for electrical schemes, which are often highly specialized and lack physical implementation, making rapid simulation of substation construction impossible. Therefore, even with modular prefabricated substations, it is difficult to quickly assess whether the land conditions are suitable when facing extremely irregular land use. In conclusion, urban substation construction faces land acquisition difficulties, and the potential for unfeasible land-related problems during the decision-making phase of substation construction remains undetected. Summary of the Invention

[0003] The primary objective of this invention is to overcome the shortcomings and deficiencies of existing technologies and provide a portable simulation substation device suitable for prefabricated substations. This device is simple in structure, portable, and can achieve rapid simulation substation construction and adapt to different sites.

[0004] The second objective of this invention is to provide a simulation construction method suitable for prefabricated substations.

[0005] The objective of this invention is achieved through the following technical solution: a portable simulation substation construction device suitable for prefabricated substations, comprising several magnetic blocks and a metal plate for attracting the magnetic blocks. The magnetic blocks are projected according to a preset ratio based on the prefabricated substation. Each magnetic block is printed with the electrical design content of the corresponding prefabricated substation, including the scale of electrical equipment, parameter package name, price, and splicing edge information. The magnetic blocks have three different background colors, and the magnetic blocks with different background colors are used to represent different land occupation conditions of the corresponding prefabricated substations. The metal plate contains land boundary information.

[0006] Preferably, the background color of the magnetic blocks includes red, green and transparent. Red magnetic blocks are used to indicate the ground layout of the corresponding prefabricated cabin, green magnetic blocks are used to indicate the ground layout of the corresponding prefabricated cabin or are arranged on the red magnetic blocks, and transparent magnetic blocks are used to indicate that the corresponding prefabricated cabin does not require a ground layout.

[0007] Preferably, the preset ratio is in the range of 1:200 to 1:40.

[0008] Preferably, the magnetic block is a rectangular magnetic block.

[0009] Preferably, the metal plate has a size greater than 297mm by 420mm.

[0010] Preferably, the parameter package name includes the device type and quantity, and the device type is represented by Pinyin.

[0011] Preferably, the price includes the price of electrical equipment and prefabricated modules, but excludes the price of civil engineering and land.

[0012] Preferably, the frame of the transparent magnetic block is a stretchable frame.

[0013] A simulation construction method applicable to prefabricated substations, using the aforementioned apparatus, includes the following steps:

[0014] S1. Print the land boundary of the proposed substation on the drawing according to the selected scale, and place the drawing on a metal plate;

[0015] S2. Select the required magnetic blocks according to the construction scale of the proposed substation;

[0017] S4. Determine whether all red and green magnetic blocks have been placed within the land boundary:

[0018] If so, it means the land use is feasible, and we can proceed to the next step;

[0020] S5. Arrange transparent magnetic blocks within the land boundary area;

[0021] S6. Calculate the total construction cost of the substation by combining all the magnetic blocks arranged on the drawings.

[0022] Preferably, the formula for calculating the total construction cost of the substation in step S6 is:

[0023] Z = ∑P 红色 +∑P 绿色 +∑P 透明 ,

[0024] Where Z represents the total construction cost of the substation, ∑P 红色 ,∑P 绿色 ,∑P 透明 These represent the prices on the panels for all red blocks, all green blocks, and all transparent blocks, respectively.

[0025] The present invention has the following advantages and effects compared with the prior art:

[0045] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0046] Example 1

[0047] like Figure 1-15As shown, a portable simulation substation construction device suitable for prefabricated substations includes several magnetic blocks and a metal plate for attracting the magnetic blocks. The magnetic blocks are projected according to a preset ratio based on the prefabricated substation. Each magnetic block is printed with the corresponding electrical design content of the prefabricated substation, including the scale of electrical equipment, parameter package name, price, and splicing edge position information. The magnetic blocks have three different background colors, and the magnetic blocks with different background colors are used to represent different land occupation conditions of the corresponding prefabricated substation. The metal plate contains land boundary information.

[0048] Specifically, the portable simulation substation device of this invention first forms rectangular magnetic blocks by miniaturizing the projection of modular prefabricated modules according to a preset ratio (this invention only considers the length and width of the prefabricated modules, not the height, to solve the land use problem); then, the electrical design details of each unit module of the prefabricated substation are printed on the panel of the magnetic blocks, so that the magnetic blocks can be manually assembled and spliced ​​on a metal plate. The electrical design details include the scale of electrical equipment (including equipment information and wiring), parameter package names, the position of the splicing edge (i.e., the side of the seamless splicing between modules), and the manufacturing dimensions of the magnetic blocks. The parameter package name includes the equipment type and quantity, where the equipment type is represented by pinyin, for example... Figure 2 ZB-ft-1 indicates that the equipment type is a split-type main transformer, and the quantity of main transformers is 1 unit; the price includes the price of electrical equipment and unit compartments, but excludes the price of civil engineering and land, such as Figure 2 The price in the middle is 1.55 million;

[0049] In actual engineering projects, when multiple prefabricated modules of the same model are spliced ​​into a modular prefabricated module, the splicing is mainly carried out by expanding the length and width of the module. In order to better meet the needs of on-site assembly, the magnetic block panel also includes the position information of the splicing edge.

[0050] In this embodiment, iron plate is used as the metal plate, which is low in cost and easy to manufacture. The size of the metal plate is greater than 297mm x 420mm. Specifically, in application, the metal plate needs to be used to clamp a standard design drawing (standard size is 3A, i.e., 297mm x 420mm), therefore the size of the metal plate should be larger than this size. This design ensures the practicality and convenience of the device.

[0051] The specific operation of the projection involves projecting the modular prefabricated cabin according to a preset ratio and ensuring stable magnetic adsorption, thereby effectively controlling the footprint error. The preset ratio can be selected according to actual needs, with a range of 1:200 to 1:40. In this embodiment, the preset ratio is set to 1:100 to clearly display the information on the magnetic panel. Figures 2-15 The actual dimensions of the magnetic block are in mm. Figure 2The actual dimensions are 10500mm x 8100mm. When manufactured at a 1:100 scale, the magnetic block's dimensions are 105mm x 810mm. This device is simple in structure, portable, and low in manufacturing cost. It materializes the prefabricated cabin, simplifies the footprint, enables rapid simulation of substation construction, and solves the land use problem for substations.

[0052] The background color of the magnetic blocks includes red, green and transparent. Red magnetic blocks are used to indicate the ground layout of the corresponding prefabricated cabin, green magnetic blocks are used to indicate the ground layout of the corresponding prefabricated cabin or the layout on the red magnetic blocks (i.e., a two-layer layout), and transparent magnetic blocks are used to indicate that the corresponding prefabricated cabin does not require a ground layout (i.e., the layout on the red or green magnetic blocks).

[0053] Specifically, the purpose of this invention is to solve the land use problem, therefore it also considers whether the prefabricated modules occupy land: if they must be laid on the ground, then they occupy land. In this embodiment, red, green, and transparent background colors are used to represent land occupation (ground-based), land-occupying (can be laid on the ground or on a second floor), and no land occupation, respectively. Figure 1 As shown in Figure (a), a concentrated layout is used for relatively regular plots of land. The area within the red dashed line represents the plot area (the red dashed line indicates the land boundary). Red rectangles represent red magnetic blocks, green rectangles represent green magnetic blocks, and black rectangles represent transparent magnetic blocks. The borders of the transparent magnetic blocks are stretchable, meaning they can be stretched or shortened within a set range, offering great flexibility.

[0054] In Figures (a) and (b), by flexibly using three different magnetic block layouts, the site layout can be completed within the land boundary. In practical applications, three other different colors can be used to distinguish the different land occupation of each prefabricated module unit, depending on the requirements.

[0055] In this embodiment, the construction of a 35kV substation was simulated to obtain... Figures 2-15 The diagram shows the detailed drawings of the magnetic blocks corresponding to the modular prefabricated unit compartments. The red magnetic blocks include the main transformer unit compartment and the switchgear unit compartment, the green magnetic blocks include the station service transformer unit compartment and the grounding transformer unit compartment, and the transparent magnetic blocks include the secondary equipment unit compartment. In practical applications, designers can select the appropriate unit compartments according to the electrical scale and equipment selection.

[0056] Example 2

[0057] like Figure 16 The diagram shows a schematic flow chart of a simulated substation construction method applicable to prefabricated substations, using the apparatus described in Example 1, including the following steps:

[0058] S1. Print the land boundary of the proposed substation on the drawing according to the selected scale, and place the drawing on a metal plate;

[0059] S2. Select the required magnetic blocks according to the construction scale of the proposed substation;

[0060] S3. Arrange red magnetic blocks and green magnetic blocks sequentially within the land boundary area, wherein the green magnetic blocks are arranged independently on the drawing or on top of the red magnetic blocks;

[0061] S4. Determine whether all red and green magnetic blocks have been placed within the land boundary:

[0062] If so, it means the land use is feasible, and we can proceed to the next step;

[0063] If not, it means the land use is not feasible, and the website construction operation will be terminated;

[0064] S5. Arrange transparent magnetic blocks within the land boundary area;

[0065] S6. Calculate the total construction cost of the substation by combining all the magnetic blocks arranged on the drawings.

[0066] Specifically, in this embodiment, the selected ratio is set to 1:100, and the land boundary of the proposed substation (see...) is... Figure 1 Print out a drawing (marked by the red dotted line) at a 1:100 scale and place it flat on the metal plate. If all the required red and green magnetic blocks can be placed within the area marked by the red line, the site is feasible; otherwise, it is not. If the site is feasible, then arrange the transparent magnetic blocks. The borders of the transparent magnetic blocks are stretchable (they can be extended or shortened within a set range) and can be adjusted according to actual needs. Figure 16 As shown, in this embodiment, the dimensions of the transparent magnetic block are: length 80mm to 140mm and width 40mm to 100mm. The size range can be selected according to the actual electrical scale and land area, and it can also be flexibly stretched during the construction and layout.

[0067] The formula for calculating the total construction cost of the substation in step S6 is as follows:

[0068] Z = ∑P 红色 +∑P 绿色 +∑P 透明 ,

[0069] Where Z represents the total construction cost of the substation, ∑P 红色 ,∑P 绿色 ,∑P 透明 Let P represent the prices on the panels for all red, all green, and all transparent magnetic blocks, respectively. 透明 The cost needs to be estimated based on the actual size of the prefabricated cabin corresponding to the transparent magnetic block.

[0070] In summary, the simulation construction method for prefabricated substations provided by this invention is simple to operate, greatly improves the efficiency of simulation construction, and facilitates the timely detection of land use issues by combining and splicing various magnetic blocks within the land boundary.

[0071] The above embodiments are preferred embodiments of the present invention and are not intended to limit the present invention. Any changes or other equivalent substitutions made without departing from the technical solution of the present invention are included within the protection scope of the present invention.
