[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Currently, in the relevant technical field, the design of wind farm turbine hoisting platforms is largely based on manual selection. With the continuous development of the new energy sector, the requirements for selecting hoisting platform locations are gradually increasing. This requires not only platform size but also the integration of wind turbine layout and relevant topographical and geological conditions. For example, there is a lack of automatic design of hoisting platform locations and design parameters based on certain data. This makes it difficult to clearly determine the rationality of hoisting platform placement and the amount of work required, resulting in limited operability.

[0040] To address this issue, various embodiments of the present invention are provided for a method for automatically designing a wind farm unit hoisting platform. This method provides a highly operable method for generating a wind farm hoisting platform with automatic design capabilities. While ensuring accurate analysis of selected wind turbine hoisting requirements and calculation of wind farm hoisting platform engineering quantities, it reduces reliance on experience and improves hoisting platform design efficiency. This method allows for the design requirements to be met with minimal engineering effort, automatically designing the hoisting platform based on the turbine model and geological topography.

[0041] The embodiment of the present invention provides a method for automatically designing a wind farm unit hoisting platform, referring to Figure 1 , Figure 1 The figure is a flow chart of an embodiment of the method for automatically designing a hoisting platform for a wind farm unit according to the present invention.

[0042] In this embodiment, the method for automatically designing a wind farm unit hoisting platform includes the following steps:

[0043] 1) Platform size design

[0044] Because the lifting platform's shape varies greatly, the initial design phase can be simplified to a fixed rectangular form. Considering that unit capacity, hub height, and crane size are generally proportional to blade length, the lifting platform's dimensions can be controlled based on blade length and equipment stacking pattern.

[0045] By establishing a database that can be continuously maintained and updated, the size of the lifting platform can be directly obtained based on the selected equipment stacking type and the blade length.

[0046] 2) Design of the initial plane position of the platform

[0047] By automatically retrieving the center coordinates of the camera, according to the platform size determined in the previous step, Figure 2 As shown, the platform is arranged with the long side as the east (when A≥B, side A is the east) and the platform centroid as the center of the machine position, which is the initial position of the platform.

[0048] 3) Initial platform elevation design

[0049] Considering that the platform design elevation control is different in mountainous, plain and tidal flat areas, the platform elevation can be controlled in advance.

[0050] 4) Final platform plane position design

[0051] Based on the initial elevation determined in 3) and the initial position determined in 2), the proposed platform is automatically rotated 5° counterclockwise around the center of the platform, forming a new platform calculation unit. The cut and fill volume for each unit is calculated. The volume includes both cut and fill, and slopes are not considered. All 72 units are rotated 360°, and the angle with the minimum cut and fill volume is used as the final planar position.

[0052] 5) Final platform elevation design

[0053] According to the final plane position determined in 4), set the excavation slope ratio and backfill slope ratio, and automatically adjust the platform design elevation.

[0054] According to the general rules for selecting the location of the lifting platform, the elevation with the smallest excavation difference is selected as the final design elevation.

[0055] This embodiment provides a method for automatically designing a hoisting platform for wind farm turbines. This method enables rapid iteration of multiple solutions and recommends the hoisting platform solution with the highest engineering effort based on the LCOE optimization principle. Wind farm design engineers can quickly design matching technical solutions, improving work efficiency. This method is highly practical and fills a gap in the field of automated design and engineering quantity calculation for wind farm turbine hoisting platforms.

[0056] In order to explain the present application more clearly, a specific example of an automatic design method for a wind farm unit hoisting platform is proposed.

[0057] In this embodiment, a method for automatically designing a wind farm unit hoisting platform includes the following specific implementation steps.

[0058] 1) Platform size design

[0059] Because the lifting platform's shape varies greatly, the initial design phase can be simplified to a fixed rectangular form. Considering that unit capacity, hub height, and crane size are generally proportional to blade length, the lifting platform's dimensions can be controlled based on blade length and equipment stacking pattern.

[0060] By establishing a database that can be continuously maintained and updated, the size of the lifting platform can be directly obtained based on the selected equipment stacking type and the blade length.

[0061] Equipment is not stacked on the platform, and all equipment on the platform can be lifted as soon as it arrives; recommended platform dimensions are given based on blade length.

[0062] Some equipment is stacked on the platform, considering stacking the tower nacelle and other small equipment, and the remaining equipment can be hoisted as it arrives; the recommended platform size is given according to the blade length.

[0063] All equipment is stacked on the platform, considering all unit equipment. After the vehicle is in place, it is hoisted in sequence. The recommended platform size is given according to the blade length.

[0064] 2) Design of the initial plane position of the platform

[0065] By automatically retrieving the center coordinates of the camera, according to the platform size determined in the previous step, Figure 2 As shown, the platform is arranged with the long side as the east (when A≥B, side A is the east) and the platform centroid as the center of the machine position, which is the initial position of the platform.

[0066] 3) Initial platform elevation design

[0067] Considering that the platform design elevation control is different in mountainous, plain and tidal flat areas, the platform elevation can be controlled in advance.

[0068] ① Project the foundation outline onto the terrain, offsetting the lowest point elevation downward by Xm (X as input). This serves as the initial elevation. The subsequent design elevation in step 5) should not exceed this design elevation. This method is primarily applicable to mountainous wind farms where foundations cannot be located in backfill areas and platform elevation is affected by foundation location.

[0069] ② Project the foundation outline onto the terrain, and use the average elevation of the lowest and highest points as the initial elevation. The subsequent 5) design elevation can be adjusted up or down. This is mainly applicable to plain areas, where the foundation elevation requirements are not high, and the main consideration is the working conditions of the platform earthwork balance.

[0070] ③ Project the foundation contour onto the terrain, offsetting the corresponding highest point elevation upward by Xm (X is the input) as the initial elevation. The subsequent design elevation in step 5) should not be lower than this design elevation. This is primarily applicable to tidal flat wind farms, where the design elevation cannot be lower than the construction water level or flood level.

[0071] 4) Final platform plane position design

[0072] Automatically calculate the cut and fill volume of the proposed platform based on the initial elevation determined in 3) and the initial position determined in 2). The proposed platform is rotated 5° counterclockwise with the center point of the machine position as the center of the circle, and the cut and fill volume is calculated as a new platform unit. The project volume includes cut and fill, and the slope can be ignored. Rotate 360° to calculate all 72 units and take the angle with the minimum cut and fill volume as the final plane position, such as Figure 3 shown.

[0073] 5) Final platform elevation design

[0074] According to the final plane position determined in 4), set the excavation slope ratio and backfill slope ratio, and automatically adjust the platform design elevation.

[0075] If the first elevation control method is selected in 3), the cut and fill quantities are calculated based on the initial elevation plus the slope, and the elevation is automatically adjusted downward by 0.5m as a unit based on the initial elevation and the cut and fill quantities are calculated. The calculation is repeated 20 times, and the cut and fill difference, cut quantity - fill quantity, is taken. The smallest elevation is used as the final design elevation, and this solution is the final platform design solution.

[0076] If the second elevation control method is selected in 3), the cut and fill quantities are calculated based on the initial elevation plus the slope, and the elevation is automatically adjusted upward by 0.5m as a unit based on the initial elevation and the cut and fill quantities are calculated six times. The elevation is automatically adjusted downward by 0.5m as a unit based on the initial elevation and the cut and fill quantities are calculated 14 times. The cut and fill difference, cut quantity - fill quantity, is taken as the final design elevation. This solution is the final platform design solution.

[0077] If the third elevation control method is selected in 3), theoretically the initial elevation is the final elevation, and the cut and fill quantities are calculated by adding the slope, which is the final platform design scheme.

[0078] 6) Other project designs

[0079] This area is mainly used to fill in other engineering items that need to be set up for each platform, such as replacement fill, retaining walls, drainage ditches, surface layer of crane area, etc. The sub-item name, unit, and engineering quantity need to be manually input, and only the single unit quantity needs to be entered.

[0080] 7) Provide a bill of quantities based on the final platform design parameters, including: land area, topsoil clearance, earth excavation, stone excavation, backfill, and others.

[0081] Engineering quantity algorithm:

[0082] Land area: Sum the land area of ​​each platform obtained in 5) to get the total land area of ​​the platform for the project.

[0083] Topsoil cleaning: The surface clearing area should be consistent with the land area.

[0084] Excavation: Sum the excavation volume of each platform obtained in 5) to obtain the total excavation volume of the project platform, and calculate the excavation quantity based on the preset soil-rock ratio.

[0085] Stone excavation: Sum the excavation volume of each platform obtained in 5) to obtain the total excavation volume of the project platform, and calculate the amount of stone excavation based on the preset soil-rock ratio.

[0086] Fill: Sum up the fill volume of each platform obtained in 5) to obtain the total fill and excavation volume of the platform for the project.

[0087] Others: If the sub-item name, unit, and project quantity are entered according to 6), fill in the corresponding form. The project quantity should be the input single unit quantity multiplied by the total number of wind turbines.

[0088] This embodiment provides a method for automatically designing a hoisting platform for wind farm turbines. This method enables rapid iteration of multiple solutions and recommends the hoisting platform solution with the highest engineering effort based on the LCOE optimization principle.
