[0002] When the wind turbines of a mountain wind farm are installed and arranged on a hillside, the safe operation of the wind turbines is the main issue that needs to be considered.
[0003] At present, in the existing technology, a common situation is that the boundary of the restrictive factor is located exactly at the watershed at the top of the mountain. In order to avoid the machine position occupying the restrictive factor, the wind turbine position must be fine-tuned in the direction of the mountain. In this case, the wind turbine position is located on the hillside, and the corresponding wind turbine hoisting platform may produce a higher excavation slope. The distance between the high slope and the wind turbine is manually judged, and when the distance between the high slope and the wind turbine is too small, it is possible to enter the safe operating envelope of the wind turbine blades, which will cause great safety hazards to the safe operation of the wind turbine. Usually, when designing the layout of wind turbines in mountain wind farms on hillsides, the number of elevation points and contour lines in the topographic map is large and irregularly distributed, resulting in a large workload and low efficiency for manual risk judgment and wind turbine positioning.

Figure 1 As shown, the method includes the following steps 101, 102, 103 and 104.
[0033] Step 101: Acquire on-site measured information of a target mountain wind farm, coordinate information of control points of the field leveling boundary line, and position information of wind turbine positions.
[0034] In this step, the field leveling line is the boundary line of the measurement range of the target mountain wind farm, the wind turbine position is the installation position of the wind turbine, and the position information includes the position coordinate point information.
[0035] Among them, the target mountain wind farm is a pre-acquired mountain where wind turbines need to be set up. When the target mountain wind farm is clear (that is, the target mountain wind farm has been determined and the wind turbine construction can be carried out), the on-site measured information is the three-dimensional elevation information of the wind turbine position of the target mountain wind farm obtained by means of drone aerial photography, lidar point cloud, etc., and this embodiment does not limit this; when the target mountain wind farm is unclear (that is, the target mountain wind farm has not been determined and the wind turbine construction has not yet started), the on-site measured information is obtained by modeling the elevation data captured by satellite downloaded from the topographic map data website, and this embodiment does not limit this.
[0036] Specifically, after obtaining the on-site measured information of the target mountain wind farm, data modeling is performed based on the on-site measured information to obtain data modeling results, and then the coordinates of each key control point of the field leveling boundary line of the target mountain wind farm are identified based on the data modeling results to obtain the coordinate information of the control points of the field leveling boundary line.
[0037] When the target mountain wind farm is clearly defined, the position information of the wind turbine position is clarified. The position information includes the position coordinate point information P (X, Y, Z) of the wind turbine position (where X represents the horizontal coordinate of the wind turbine position, Y represents the vertical coordinate of the wind turbine position, and Z represents the field elevation of the wind turbine position), the hub height, the wind turbine operating safety radius, and the altitude of the wind turbine's impeller center. The altitude of the wind turbine's impeller center is the sum of the hub height and the wind turbine's field elevation, which is not limited in this embodiment.
[0038] Step 102: Determine the three-dimensional terrain model of the target mountain wind farm based on the on-site measured information and the control point coordinate information, determine the safety envelope sphere range of the target mountain wind farm based on the machine position coordinate point information, and determine the wind turbine coordinate system of the target mountain wind farm based on the machine position information.
[0039] In this step, the three-dimensional terrain model is constructed based on on-site measured information and control point coordinate information, the safety envelope sphere range is the spatial safety envelope sphere range constructed based on the machine position information and with the machine position coordinate point information as the sphere center, and the wind turbine coordinate system is a polar coordinate system established based on the machine position information.
[0040] In a specific embodiment, the machine position information also includes the hub height of the wind turbine, the safe operating radius of the wind turbine and the altitude of the impeller center of the wind turbine; the control point coordinate information is a collection of point coordinate information of all key points of the field leveling boundary line; the three-dimensional terrain model of the target mountain wind farm is determined based on the on-site measured information and the control point coordinate information, including: determining the initial measurement site of the target mountain wind farm based on the on-site measured information; fitting the point coordinate information of all key points in the field leveling boundary line of the initial measurement site to determine the three-dimensional terrain model of the target mountain wind farm; determining the safety envelope sphere range of the target mountain wind farm based on the machine position coordinate point information of the machine position information, including: inputting the machine position coordinate point information, the hub height, the safe operating radius of the wind turbine and the altitude of the impeller center of the wind turbine into the construction software to obtain the safety envelope sphere range output by the construction software; wherein the construction software is software for sphere construction; determining the wind turbine coordinate system of the target mountain wind farm based on the machine position information, including: establishing the wind turbine coordinate system based on the machine position coordinate point information.
[0041] Specifically, after obtaining on-site measurement information, control point coordinate information, and turbine position information, the initial measurement site of the target mountain wind farm is determined based on the on-site measurement information. Then, the control point coordinate information is determined based on the coordinate information of all key points within the field boundary of the initial measurement site. The control point coordinate information is input into the construction software, which then fits the control point coordinate information to form a closed polygon and establishes a 1:1 data model. The three-dimensional terrain model of the target mountain wind farm is output by the construction software. The turbine position coordinate information, hub height, wind turbine operating safety radius, and turbine rotor center elevation are input into the construction software to obtain a safety envelope sphere. The construction software may, for example, be the Geospatial Data Abstraction Library (GDAL), which is not limited in this embodiment. The turbine position pole (X, Y) is determined based on the horizontal and vertical coordinates of the turbine position coordinate information. A ray projected from the turbine position pole toward due north is used as the polar axis to establish a wind turbine coordinate system, which is not limited in this embodiment.
[0042] Step 103 : determining a slope sweeping interval when it is determined that the wind turbine blades of the target mountain wind farm have a slope sweeping risk based on the three-dimensional terrain model, the safety envelope sphere range, and the wind turbine coordinate system.
[0043] In a specific embodiment, after determining the three-dimensional terrain model of the target mountain wind farm based on the on-site measured information and the control point coordinate information, determining the safety envelope sphere range of the target mountain wind farm based on the machine position coordinate point information of the machine position information, and determining the wind turbine coordinate system of the target mountain wind farm based on the machine position information, it also includes: determining the scanning ray and the rotation angle of the scanning ray; cutting the three-dimensional terrain model, the safety envelope sphere range and the wind turbine coordinate system according to the scanning ray and the rotation angle to obtain the target section; determining the absolute elevation of the ground line and the absolute elevation of the spatial safety envelope sphere of the target section; obtaining the elevation difference corresponding to the target section based on the difference between the absolute elevation of the ground line and the absolute elevation of the spatial safety envelope sphere corresponding to the target section; and determining whether the wind turbine blades of the target mountain wind farm have a slope sweeping risk based on the elevation difference corresponding to the target section and the elevation difference threshold.
[0044] In this step, the rotation angle of the scanning ray is a fixed rotation angle, and the fixed rotation angle is used as the step size. The smaller the rotation angle, the higher the calculation accuracy, which is not limited in this embodiment.
[0045] Specifically, after determining the wind turbine position extreme point, Figure 2 is a cross-sectional schematic diagram of the target mountain wind farm provided by the present invention, such as Figure 2 As shown, Figure 2The legend in the diagram includes the site level line, polar axis, section line, excavation slope, contour line, and wind turbine foundation. The area formed by the excavation slope and the long flat line is the initial measurement site. The contour line is a closed curve formed by connecting points of equal altitude on the target mountain wind farm. The wind turbine foundation is the range determined by the wind turbine position pole and the wind turbine blades. Sweep rays are emitted from the wind turbine position pole and rotated at a fixed angle. As the step size, rotate a ray uniformly counterclockwise (i.e. Figure 2 ), the three-dimensional terrain model, the safety envelope sphere range and the field level edge line are sectioned to obtain n sections, where n is a positive integer greater than or equal to 1. Any section can be a target section. For any target section, the absolute elevation of the ground line and the absolute elevation of the spatial safety envelope sphere of the target section are determined. The elevation difference corresponding to the target section is obtained based on the difference between the absolute elevation of the ground line and the absolute elevation of the spatial safety envelope sphere corresponding to the target section. The elevation difference corresponding to the target section and the elevation difference threshold are used to determine whether there is a risk of wind turbine blades in the target mountain wind farm sweeping.
[0046] Specifically, Figure 3 It is a cross-sectional analysis schematic diagram provided by the present invention, such as Figure 3 As shown, Figure 3 The red line in the figure indicates the hub height of the wind turbine, the radius of the small circle is the length of the wind turbine blade, and the radius of the large circle is the wind turbine safe operation radius. For any target profile, starting from the machine position coordinate point information P, read any point on the target profile one by one with a uniform step size d. Absolute elevation of the ground line at and the absolute elevation of the spatial safety envelope sphere at the corresponding position , and then according to any point on the target profile Absolute elevation of the ground line at and the absolute elevation of the spatial safety envelope sphere at the corresponding position The difference between them determines any point on the target profile The elevation difference at . Determine any point on the target profile The elevation difference at Is it greater than or equal to 0? If it is greater than or equal to 0, continue calculating The elevation difference at After traversing all step lengths d, if the obtained elevation differences are all greater than or equal to 0, it is determined that there is no risk of wind turbine blades colliding with the mountain at the current target profile Pn. If it is determined that there is no risk, the calculation continues to return to the blade collision situation of the target profile n+1 to determine whether there is a risk of wind turbine blades colliding with the mountain at the target profile n+1, until all n target profiles are judged.
[0047] exist If it is less than 0, further adopt the dichotomy method, with d / 2 as the new step size, at the previous point At the current calculation Insert new Point, and continue to calculate in a loop to get The coordinates of the point and The distance S1-n between the point and the pole and The absolute height H1-n of the point is recorded (such as Figure 3 After determining point E, take point E as the new starting point and continue forward with a new uniform step length. Read the absolute elevation of the ground lines one by one and the absolute elevation of the spatial safety envelope sphere at the corresponding position , the new uniform step size The advantage of this setting is that it can more accurately read the absolute elevation of the ground line of each point within the collision range. and the absolute elevation of the spatial safety envelope sphere at the corresponding position Continue to repeat the calculation of elevation difference and continue to calculate the absolute elevation of the ground line. and the absolute elevation of the spatial safety envelope sphere at the corresponding position Re-determine the elevation difference , determine the re-determined elevation difference Is it less than 0, in the re-determined elevation difference If it is less than 0, the current re-determined elevation difference is recorded. ; In the re-determined elevation difference If it is greater than or equal to 0, continue to use the binary search method with a step size of d / 2. At the current calculation Insert new Point, and continue to calculate in a loop to get The coordinates of the point and The distance between the point and the pole is S2-n and The absolute height H2-n of the point is recorded (such as Figure 3At this point, the yellow mountain between points C and E is the range of the mountain that intrudes into the safe edge of the wind turbine blade tip, thus confirming that the wind turbines in the target mountain wind farm are at risk of sweeping the slope during operation.
[0048] In the case of a slope sweep risk in any target section, the three-dimensional terrain model, the safety envelope sphere range and the field level edge line are further sectioned using the dichotomy method to As the new step length, insert a new section m between the previous section n-1 and the current section n, where m is a positive integer greater than or equal to 1. Then, for any newly inserted section, continue to determine the sweeping risk of section m, so as to obtain the starting position of blade sweeping, and record the angle between the section and the polar axis. After the blade sweeping starting position is obtained, the section is used as the new starting point and the new uniform step length is continued. Generate sweeping rays to slice through the 3D terrain model, the safety envelope sphere, and the field boundaries one by one. Should be less than The advantage of this setting is that the blade sweeping situation of the profile within the sweeping range can be read more accurately. In the process of cyclic determination of the sweeping risk, when the profile Pn does not have the risk of blade collision with the mountain again, the dichotomy method is used to As the step size, insert a new section m between the previous section n-1 and the current section n, and continue to determine whether there is a risk of slope sweeping in any section until the end position of the blade slope sweeping is obtained, and record the angle between the section and the polar axis When there is no blade sweep risk in all sections, it is determined that there is no blade sweep risk in the target mountain wind farm. When there is a risk of blade sweeping, determine the sweeping interval as .
[0049] Step 104 : Determine blade sweeping analysis results of wind turbines in the target mountainous wind farm according to the sweeping interval.
[0050] In a specific embodiment, determining the blade sweeping analysis results of the wind turbines in the target mountain wind farm based on the sweeping interval includes: determining the target earthwork volume of the target mountain wind farm based on the sweeping interval; wherein the target earthwork volume is the result of finite element mesh analysis of the sweeping interval; and determining the blade sweeping analysis results of the wind turbines in the target mountain wind farm based on the target earthwork volume.
[0051] In a specific embodiment, the target earthwork volume of a target mountain wind farm is determined based on the slope sweeping interval, including: determining the regional division angular step; dividing the slope sweeping interval into regions according to the regional division angular step to obtain a division profile; establishing a local coordinate system for the division profile; establishing a three-dimensional earthwork volume calculation model based on the local coordinate system; wherein the three-dimensional earthwork volume calculation model includes a slope cutting objective function and constraint conditions; and determining the target earthwork volume based on the slope cutting objective function and the constraint conditions.
[0052] Specifically, after determining the slope sweeping interval, , determine the preset area division angle step size as , the slope sweeping interval is divided into regions according to the regional division angle step, that is, according to The step size divides the sweeping interval into Q finite element calculation units, each finite element calculation unit corresponds to a risk profile (division profile) Pv (m=1, 2...Q). Then, a local coordinate system is established for each risk profile Pv, with the impeller center projection point O of the wind turbine as the origin, the section direction as the X axis, and the vertical direction as the Z axis. The area CE is discretized into Calculation nodes, each node corresponds to the coordinates (x_k, z_k), according to each node corresponding to the coordinates (x_k, z_k), the three-dimensional earthwork calculation model is established, the three-dimensional earthwork calculation model includes the slope cutting objective function and constraint conditions, the slope cutting objective function , constraints .in, for The slope cutting height of the point, for The influence area weight coefficient of the point, for The safety envelope elevation of the point, is a pre-set threshold parameter, is the safety margin, For example, it may be 0.5-1.0 meters, which is not limited in this embodiment.
[0053] After determining the three-dimensional earthwork calculation model, a relaxation variable is further introduced into the slope cutting objective function. , the augmented objective function is constructed as Then, the augmented objective function and constraint conditions are input into the model building software, and the ecological impact assessment model is established through the model building software. The ecological impact index is determined through the ecological impact assessment model. ,in, Represents the ecological sensitivity coefficient matrix, which is mainly used to identify vegetation types based on satellite images. For example, it can be , this embodiment does not limit this. For the unit ( ) of the excavation area, and finally according to the ecological impact index Constructing multi-objective optimization equations ,in, + =1, For example, it can be 0.6-0.8, For example, it can be 0.2-0.4. It represents the total earthwork volume of the initial measurement site of the target mountain wind farm. Finally, the target earthwork volume is obtained by solving the multi-objective optimization equation.
[0054] In a specific embodiment, a blade sweep analysis result of a wind turbine in a target mountain wind farm is determined based on a target earthwork volume, including: determining a three-dimensional slope cutting surface based on the target earthwork volume and slope cutting surface construction software; wherein the slope cutting surface construction software is software that spatially interpolates the divided profile based on the target earthwork volume to construct a continuous three-dimensional slope cutting surface; performing surface smoothing on the three-dimensional slope cutting surface to obtain a target three-dimensional slope cutting surface; determining a blade sweep analysis result based on the target three-dimensional slope cutting surface and surface analysis software; wherein the surface analysis software is software that analyzes the target three-dimensional slope cutting surface.
[0055] In this step, the slope cutting surface construction software may be, for example, a math library (a mathematical function library), a numpy library (an extension library used for scientific computing and data processing), etc., which is not limited in this embodiment.
[0056] The surface analysis software is software used to extract engineering parameters of a target three-dimensional slope cutting surface, which is not limited in this embodiment.
[0057] Specifically, after obtaining the target earthwork volume, the target earthwork volume and each profile are input into the slope cutting surface construction software. The slope cutting surface construction software uses the Kriging interpolation method (spatial autocovariance optimal interpolation method, a very useful address statistical gridding method) to spatially interpolate the optimal slope cutting elevation points of each profile to construct a continuous three-dimensional slope cutting surface. Then, the cubic spline function (a piecewise interpolation method that can generate a smooth and continuous curve) is applied to smooth the three-dimensional slope cutting surface to eliminate the sudden changes between adjacent profiles, and the curvature constraint condition is set as ,in, For example, 0.15-0.3 can be taken, and the corresponding slope ratio is 1:3.3-1:7, thereby obtaining the target three-dimensional slope cutting surface; finally, the target three-dimensional slope cutting surface is input into the surface analysis software to obtain the blade sweeping analysis result output by the curve analysis software.
[0058] In a specific embodiment, after obtaining the blade slope sweeping analysis results, the blade slope sweeping analysis results can be further verified for safety. The optimized terrain model after optimization is determined based on the blade slope sweeping analysis results, and then it is determined whether the optimized terrain model has a slope sweeping risk. If there is still a slope sweeping risk, the newly generated collision point coordinates are recorded, and the new collision point coordinates are added as constraints to solve the slope cutting objective function, and a new slope sweeping interval is determined, thereby determining a new blade slope sweeping analysis result, and the iteration is repeated until the collision risk position is completely eliminated.
[0059] For example, taking a 5MW wind turbine platform as an example, a drone equipped with a lidar scans a 200-meter range around the platform to obtain on-site measurement information with an accuracy of 0.2 meters, and determines the Figure 2 The network-like terrain in the image is extracted, and then the coordinate information of the 12 control points of the field leveling line is extracted based on the network-like terrain, and the hexagonal platform model is determined (i.e., a three-dimensional terrain model, the side length can be, for example, 15-18 meters, which is not limited in this embodiment). Then the hub height of the wind turbine of 90 meters and the safe operating radius of the wind turbine of 65 meters are input into the construction software to obtain the safe envelope sphere range. The obtained safe envelope sphere range is centered on the impeller of the wind turbine, and the coordinates of the center of the safe envelope sphere range are (X=253614.78, Y=3354872.56, Z=1532.6+90 meters). Then perform a profile analysis and set the rotation angle , a total of 72 target profiles were generated; slope intervals (slope intrusion) were found in the azimuth range of 112°-158° ( Figure 3 The maximum intrusion depth of the slope interval is 2.3 meters (at an azimuth of 135 degrees); the impact arc length range is 46 degrees (corresponding to a slope length of approximately 58 meters). After determining the slope interval, the target earthwork volume is further determined by subdividing the slope interval into 46 sections at 1 degree intervals; setting constraints: safety margin , with an ecological sensitivity coefficient of 0.7. An iterative calculation determined the target earthwork volume, with a total earthwork volume of V = 1,425 cubic meters, and 23 native trees preserved (to avoid a 5-meter safe operating radius for wind turbines). Finally, based on the target earthwork volume, the blade sweep analysis results for the target mountain wind farm were determined.
[0060] In a specific embodiment, the blade sweeping analysis results include a slope cutting range contour map, graded excavation parameters, and a material balance sheet; after determining the blade sweeping analysis results of the wind turbines of the target mountain wind farm based on the slope sweeping interval, it also includes: generating a slope cutting treatment construction drawing, a bill of quantities, and a three-dimensional visualization model of the risk area based on the slope cutting range contour map, graded excavation parameters, and the material balance sheet, and visualizing the slope cutting treatment construction drawing, the bill of quantities, and the three-dimensional visualization model of the risk area.
[0061] In this step, the interval of the slope cutting range contour map may be, for example, 1 meter, which is not limited in this embodiment.
[0062] The graded excavation parameters may include, for example, the slope height, bridleway width and comprehensive slope ratio of each graded excavation level. The slope height of each level may be, for example, less than or equal to 10 meters, the bridleway width may be, for example, greater than or equal to 2 meters, and the comprehensive slope ratio may be, for example, less than or equal to 1:1.5, etc. This embodiment does not limit this.
[0063] The material balance sheet may include, for example, the total excavation volume, the proportion of usable materials, and the amount of waste, etc. The proportion of usable materials may be greater than or equal to 70%, which is not limited in this embodiment.
[0064] Among them, the slope cutting construction drawings may include, for example, three-dimensional axonometric drawings, cross-sectional drawings, etc., the bill of quantities may include, for example, sub-item excavation volumes, support areas, ecological restoration areas, etc., and the three-dimensional visualization model of the risk area may include, for example, maximum collision depth, critical collision speed range, blade sweep frequency distribution and other annotations, which are not limited in this embodiment.
[0065] For example, the graded excavation parameters may be as shown in Table 1, and this embodiment does not limit this.
[0066] Table 1
[0067] Specifically, after determining the blade sweeping analysis results of the wind turbines in the target mountain wind farm according to the sweeping interval, the slope cutting construction drawings, bill of quantities and three-dimensional visualization model of the risk area are generated according to the slope cutting range contour map, graded excavation parameters and material balance sheet, and the slope cutting construction drawings, bill of quantities and three-dimensional visualization model of the risk area are visualized.
[0068] For example, during the graded excavation process, 6 sets of typical cross-section construction drawings (including three-dimensional axonometric relationship diagrams) can be generated, and graded excavation parameters can be output. The graded excavation parameters can be, for example, three-level excavation (8 meters per level), a 2-meter-wide horseway, and a final comprehensive slope ratio of 1:1.72. This embodiment does not limit this.
