DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0025] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0026] Embodiment 1: As described in the background technology, in actual processes, the site selection of a booster station in a mountain wind farm is restricted by factors such as the capacity of the wind farm and the terrain conditions of the site. This implementation method starts from the actual conditions and, in accordance with relevant regulations, provides a site selection method for a booster station in a mountain wind farm. The geometric dimensions of the booster station are determined by the capacity of the wind farm, and alternative site selection schemes for the booster station are proposed in accordance with the sensitive areas of the wind farm and the terrain restrictions within the site. This implementation method optimizes the alternative site selection schemes for the booster station, takes into account the weighted earthwork algorithm and the total length of the booster station from each unit, and optimizes the site selection scheme for the booster station in the mountain wind farm by comparing the total construction cost.

[0027] Specifically, the method for selecting a site for a booster station in a mountainous wind farm includes the following steps: Step 1: Determine the capacity and geometric dimensions of the booster station in a mountain wind farm. Generally, the capacity of the booster station in a wind farm is equal to the total capacity of the wind turbines connected to it. However, due to factors such as manufacturing specifications and expansion requirements, the design capacity of the booster station is often greater than the installed capacity of the wind farm. In this implementation, it is necessary to determine the capacity of the booster station transformer and land use indicators according to the capacity of the wind farm in accordance with relevant regulations. Here, the power consumption indicator table of a single wind turbine substation specified in the "Construction Land Standards for Wind Power Projects in ***" (Table 1) is taken as an example.

[0028] Table 1: Electricity consumption index table of substation for a single wind turbine.

[0029]

[0030] Step 2: Determine the limiting factors for the site selection of the mountain wind farm booster station. When selecting the site for the mountain wind farm booster station, it may be affected by a variety of limiting factors. This implementation method takes into account the influence of a variety of limiting factors, including whether there are sensitive areas and whether the terrain is flat. The limiting factors for the site selection of the mountain wind farm booster station considered in this implementation method are shown in Table 2.

[0031] Table 2: Limiting factors for site selection of booster stations in mountainous wind farms.

[0032]

[0033] Step 3: Determine the alternative site for the mountain wind farm booster station.

[0034] This implementation method comprehensively considers the boundary range of the wind farm, the determined machine site and various limiting factors of step 2, and establishes a digital elevation model (DEM) through a geographic satellite system or actual measurement. The DEM model is a kind of ordered numerical array ( x , y , z ) A solid ground model that characterizes the terrain elevation characteristics can effectively reflect the local terrain characteristics of a certain resolution and extract a variety of terrain surface features. Based on the model, the sites where booster stations are more suitable for building booster stations in the mountain wind farm area are delineated, and multiple alternative sites for booster stations in mountain wind farms are determined.

[0035] Step 4: Optimize the site selection of the booster station in the mountain wind farm.

[0036] The site selection optimization process mainly includes the comparison of earthwork volume and distance engineering volume of the alternative sites. This implementation method designs a weighted earthwork algorithm for the substation. Considering the possible complex terrain conditions in the mountains, the earthwork weighted algorithm mainly adopts the digital ground model method. Through the existing model three-dimensional coordinates (x , y , z ) Adjacent coordinate points are connected to generate a triangulated network to calculate the earthwork excavation volume of each triangular pyramid. The earthwork excavation volume of each triangular pyramid calculated by the software is superimposed to obtain the earthwork volume of the alternative site for the mountain wind farm booster station at the design elevation. Considering the influence of actual engineering factors, it is necessary to use the earthwork weighting factor to correct the calculation results. The earthwork weighting factor of this implementation method is mainly determined by terrain, environmental conditions, engineering requirements, and site factors.

[0037] (1); In the formula, e is the earthwork weighting factor; T is the terrain factor, which reflects the influence of different terrain characteristics on the earthwork volume estimation; S is the site factor, reflecting the influence of site factors such as soil type and soil quality; E It is the engineering factor, which reflects the influence of the actual conditions of the project on the earthwork estimate; En It is an environmental factor, which reflects the impact of environmental factors such as temperature and rainfall on earthwork estimation.

[0038] This implementation method establishes a weighted earthwork cost model based on the weighted earthwork algorithm of the substation. The weighted earthwork cost is mainly composed of the total excavation price, the total backfill price, the construction waste removal fee, taxes, etc. Among them, the total excavation price, the total backfill price and other items can be calculated by multiplying the corresponding earthwork volume obtained by the weighted earthwork algorithm with the corresponding unit price. The prices of other items can be obtained according to the actual construction site.

[0039] This implementation method designs a distance fitting method to calculate the distance engineering quantity. This method mainly uses the established DEM model to fit the calculation points of the distance engineering quantity. In order to improve the accuracy of the calculation, the fitting points that meet the conditions are automatically selected from the two points where the distance calculation is required, and the longer road engineering is fitted into a combination of multiple shorter roads. Taking the road A and G points to be calculated as an example, the fitting points B, C, D, E, and F are inserted in the road calculation process, and the distance calculation of road AE is converted into the sum of the distances of AB, BC, CD, DE, and EF. At the same time, considering the impact of model accuracy on the distance fitting results, the distance fitting coefficient is added for correction. The fitting distance calculation formula between any two is as follows: (2); In the formula, xA , yA,zA are the ordered numerical arrays of the DEM model of point A, xB , yB, zB They are the ordered numerical arrays of the DEM model of point B; l is the distance fitting coefficient.

[0040] This implementation method uses the distance fitting method to calculate the total distance between the booster station site and each unit. To meet the actual project requirements, the distance between the booster station site and each unit should be less than the longest connection distance of the corresponding collector line. On this basis, the road cost is determined by the road weighted cost coefficient and the road distance. The road weighted cost coefficient is the unit distance construction cost of the local road. Considering factors such as land acquisition cost, construction conditions, design cost, labor cost, and material cost, this implementation method sets a benchmark road cost coefficient to reflect the local road construction benchmark cost at the wind farm booster station site. Taking into account the different construction conditions of each section of road, the benchmark road cost coefficient is corrected to determine the road weight for each section of road. According to the distance engineering quantity calculation, this implementation method establishes a road weighted cost model: (3); (4); In the formula, Q Add weighted cost to roads; qi For the i Weighted cost coefficient of road section; Li For the i Distance of road section; αi For the i The terrain cost coefficient of the road section; βi is the slope cost coefficient of the i-th section of road; γi For the i Cost coefficient of road curvature; c is the base road cost coefficient; ei For the i Earthwork cost coefficient for road section.

[0041] On this basis, this implementation method establishes the optimization processing of alternative plans. This implementation method calculates the total cost according to the weighted earthwork cost model and the weighted road construction cost model, and calculates the unit kilometer cost price according to the ratio of the total cost to the distance engineering volume. Finally, according to the comparison of the total cost, the plan with the lowest total cost is selected as the recommended optimal plan.

[0042] The present invention comprehensively considers the site selection requirements for the booster station in a mountain wind farm, and proposes a site selection method for the booster station in a mountain wind farm, which helps to change the existing situation of relying on the experience of technical personnel to analyze the site selection of the booster station. It comprehensively considers factors such as wind farm capacity, booster station site selection restrictions, engineering earthwork weighted calculation, total distance calculation, etc., to obtain the optimal solution for the booster station in the mountain wind farm, and has good application prospects in actual engineering.
