Technical Field
[0001] The present invention relates to the technical field of wind power generation, and in particular to a method, device, equipment and medium for determining an equivalent wind speed of an impeller plane. Background Art
[0002] With the development of the times, the development of wind power projects has become increasingly critical. In order to meet the wind conditions in medium and low wind speed areas, wind turbines have shown a significant trend towards large-scale development, with the diameter of the impeller gradually expanding to 200 meters or even larger. In traditional methods, when the impeller diameter is about 100 meters, the wind speed at the hub height can basically represent the overall wind speed in the impeller plane. However, for wind turbines with an impeller diameter of more than 200 meters, the distance between the hub and the blade tip is close to 100 meters, and the wind speed at the hub can no longer effectively represent the wind speed of the entire impeller plane, resulting in a large deviation in the power generation estimate.
[0003] In the prior art, the wind speed at the impeller is mostly calculated by using a single-point wind speed value at the center of the hub or a wind shear effect model to calculate the equivalent wind speed on the impeller plane. However, the prior art only considers the impact of wind shear on the vertical wind speed. Therefore, it is difficult to accurately describe the actual wind speed on the impeller plane by using a single-point wind speed value at the center of the hub or a wind shear effect model using an equivalent wind speed algorithm. This makes it easier to cause errors in power generation assessment when the wind turbine power generation needs to be accurately calculated, leading to misjudgment of wind farm investment and construction. Summary of the invention
[0004] The present invention provides a method, device, equipment and medium for determining the equivalent wind speed of an impeller plane, so as to solve the problem in the prior art that a single-point wind speed value at the center of a hub is used to represent the impeller wind speed or that a wind shear effect model of an equivalent wind speed algorithm is used, and only the influence of wind shear on the vertical wind speed is considered, and it is difficult to accurately describe the actual wind speed of the impeller plane, which makes it more likely to cause errors in power generation evaluation in the early stage of power generation evaluation. The technical solution of the present invention obtains simulated wind speed data through fluid mechanics software, and also considers the influence of wind direction deflection on wind speed in the horizontal direction, and further determines the target equivalent wind speed of the impeller plane based on the simulated wind speed data and the attribute parameters of the target impeller, thereby improving the accuracy of the equivalent wind speed, thereby providing a good basis for accurately estimating power generation.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] In view of the above problems in the prior art, the present invention provides a method for determining the equivalent wind speed of an impeller plane. Figure 1 : is a flow chart of the method for determining the equivalent wind speed of the impeller plane provided by the present invention, such as Figure 1 As shown, the method includes the following steps 110 and 120.
[0025] Step 110: input the wind farm data corresponding to the target impeller into computational fluid dynamics software or wind farm simulation software to obtain simulated wind speed data output by the computational fluid dynamics software or the wind farm simulation software.
[0026] Specifically, the wind farm data corresponding to the target impeller can be input into the computational fluid dynamics software (CFD) to obtain the simulated wind speed data output by the computational fluid dynamics software. The CFD software can be, for example, Fluent, OpenFOAM, or other computational fluid dynamics software, and the embodiment of the present invention does not make any specific limitations here. The wind farm data corresponding to the target impeller can also be input into the wind farm simulation software to obtain the simulated wind speed data output by the wind farm simulation software. The wind farm simulation software can be, for example, Meteodyn WT, WindFarmer, or other wind farm simulation software, and the embodiment of the present invention does not make any specific limitations here.
[0027] The simulated wind speed data may be a data file in dat format, and the simulated wind speed data may be parsed in subsequent steps to obtain three-dimensional grid data containing wind speed information (i.e., wind speed data of multiple simulated points). Optionally, after obtaining the simulated wind speed data, the simulated wind speed data may be preprocessed to filter out invalid data.
[0028] In one embodiment, the wind farm data includes terrain information, surface roughness and meteorological data of the wind farm corresponding to the target impeller.
[0029] Specifically, the wind farm data includes the topographic information, surface roughness and meteorological data of the wind farm corresponding to the target impeller, and the meteorological data may include wind speed and direction. That is, the topographic information, surface roughness and meteorological data of the wind farm corresponding to the target impeller may be input into computational fluid dynamics software or wind farm simulation software to obtain simulated wind speed data.
[0030] In the above embodiment, the terrain information, surface roughness and meteorological data of the wind farm corresponding to the target impeller are input into the computational fluid dynamics software or the wind farm simulation software, so that more accurate simulated wind speed data can be obtained.
[0031] Step 120: Determine a target equivalent wind speed of an impeller plane corresponding to the target impeller based on the simulated wind speed data and the property parameters of the target impeller.
[0032] In one embodiment, the attribute parameters include: the impeller radius of the target impeller and the coordinates of the center point of the target impeller; The step of determining a target equivalent wind speed of an impeller plane corresponding to the target impeller based on the simulated wind speed data and the property parameters of the target impeller comprises: Determining a plurality of target sampling points belonging to the impeller plane based on the coordinates of the center point, the impeller radius and a preset sampling interval; Based on all the target sampling points and the simulated wind speed data, a target equivalent wind speed of an impeller plane corresponding to the target impeller is determined.
[0033] Specifically, the attribute parameters of the target impeller include the impeller radius of the target impeller and the coordinates of the center point of the target impeller. The coordinates of the center point of the target impeller can be obtained by simple calculation based on the ground point coordinates of the fan corresponding to the target impeller and the hub height of the target impeller. The coordinate system corresponding to the above coordinates can be, for example, the China Geodetic Coordinate System 2000 (CGCS2000), or other coordinate systems, which are not specifically limited in the embodiments of the present invention.
[0034] Furthermore, a plurality of target sampling points belonging to the impeller plane can be determined based on the coordinates of the center point, the impeller radius and the preset sampling interval. The preset sampling interval may include the horizontal axis interval and vertical axis interval The preset sampling interval can be set as needed, and the embodiment of the present invention does not make any specific limitation here. For example, Figure 2 is a schematic diagram of the impeller plane provided by the present invention, such as Figure 2 As shown, the red circle is the impeller plane, the intersection of the black grid is the sampling point, and the sampling point within the impeller plane is the target sampling point.
[0035] After a plurality of target sampling points belonging to the impeller plane are determined, a target equivalent wind speed of the impeller plane corresponding to the target impeller may be determined based on all the target sampling points and the simulated wind speed data.
[0036] In the above embodiment, based on the coordinates of the center point, the impeller radius and the preset sampling interval, a plurality of target sampling points belonging to the impeller plane are determined, which lays a foundation for determining the equivalent wind speed of the impeller plane.
[0037] In one embodiment, the determining of a plurality of target sampling points belonging to the impeller plane based on the coordinates of the center point, the impeller radius and a preset sampling interval comprises: Determine a plurality of initial sampling points according to a preset sampling interval; For each of the initial sampling points, based on the coordinates of the initial sampling point and the coordinates of the center point, a Euclidean distance between the initial sampling point and the center point is determined; when the Euclidean distance is less than the impeller radius, the initial sampling point is determined as the target sampling point.
[0038] Specifically, multiple initial sampling points can be determined according to a preset sampling interval, such as Figure 2 As shown, the intersections of all black grids are initial sampling points. Furthermore, it is necessary to filter the sampling points belonging to the impeller plane. Therefore, for each initial sampling point, the Euclidean distance between the initial sampling point and the center point can be determined based on the coordinates of the initial sampling point and the coordinates of the center point. Euclidean distance to the center point of the impeller plane It can be determined by the following formula: in, , and Indicates the initial sampling point The coordinates of , and Indicates the coordinates of the center point.
[0039] Furthermore, in this Euclidean distance Smaller than the impeller radius In the case of In the case of Determine the target sampling point.
[0040] In the above embodiment, for each initial sampling point, the Euclidean distance between the initial sampling point and the center point is determined based on the coordinates of the initial sampling point and the coordinates of the center point, and then when the Euclidean distance is less than the impeller radius, the initial sampling point is determined as the target sampling point, which can accurately complete the screening of the initial sampling points and obtain the target sampling point belonging to the impeller plane.
[0041] In one embodiment, the simulated wind speed data includes wind speed data of a plurality of simulated points; The step of determining a target equivalent wind speed of an impeller plane corresponding to the target impeller based on all the target sampling points and the simulated wind speed data comprises: Determine the target wind speed data corresponding to each of the target sampling points based on the wind speed data of all the simulation points and a preset interpolation method; The target equivalent wind speed of the impeller plane corresponding to the target impeller is determined based on the target wind speed data corresponding to all the target sampling points.
[0042] Specifically, the simulated wind speed data may include wind speed data of multiple simulated points. For example, on the impeller plane, there is a simulated point every fifty meters, and each simulated point has corresponding wind speed data. After all target sampling points belonging to the impeller plane are determined, the target wind speed data corresponding to all target sampling points can be determined based on the wind speed data of all simulated points and the preset interpolation method. The preset interpolation method can be, for example, the natural neighbor interpolation method, the bilinear interpolation method, the spline interpolation method, or other interpolation methods, which are not specifically limited in the embodiments of the present invention.
[0043] Furthermore, the target equivalent wind speed of the impeller plane corresponding to the target impeller may be determined based on the target wind speed data corresponding to all target sampling points.
[0044] In the above embodiment, the target wind speed data corresponding to all target sampling points are determined based on the wind speed data of all simulation points and the preset interpolation method. The preset interpolation method can smoothly interpolate the simulated wind speed data, thereby reducing the discrete error of part of the simulated wind speed data. Further, the target equivalent wind speed of the impeller plane corresponding to the target impeller is determined based on the target wind speed data corresponding to all target sampling points, so that the target equivalent wind speed can more accurately reflect the wind speed characteristics of the entire impeller plane, thereby better evaluating the power generation of the wind turbine, and the method of the present invention is simpler and more reliable than the prior art.
[0045] In one embodiment, the determining the target wind speed data corresponding to each of the target sampling points based on the wind speed data of all the simulation points and a preset interpolation method includes: The target sampling point coincident with the simulation point is determined as the first target sampling point, and the remaining target sampling points are determined as the second target sampling points; For each of the first target sampling points, determining the wind speed data of the simulation point corresponding to the first target sampling point as the target wind speed data corresponding to the first target sampling point; Based on the wind speed data of all the simulation points, the target wind speed data corresponding to all the second target sampling points are determined by the preset interpolation method.
[0046] Specifically, the simulation point may or may not coincide with the target sampling point. The target sampling point that coincides with the simulation point may be determined as the first target sampling point, and the remaining target sampling points may be determined as the second target sampling points.
[0047] For each first target sampling point, the wind speed data of the simulation point corresponding to the first target sampling point can be determined as the target wind speed data corresponding to the first target sampling point, that is, when the simulation point coincides with the target sampling point, the wind speed data of the simulation point is determined as the target wind speed data of the target sampling point.
[0048] Furthermore, based on the wind speed data of all simulation points, the target wind speed data corresponding to all second target sampling points can be determined by a preset interpolation method, that is, by interpolating the wind speed data of all simulation points, the target wind speed data of all target sampling points that do not overlap with the simulation points can be obtained.
[0049] In the above embodiment, for the target sampling point that coincides with the simulation point, the target wind speed data of the target sampling point can be directly determined without interpolation processing. For the target sampling point that does not coincide with the simulation point, the target wind speed data of the target sampling point needs to be obtained through interpolation calculation, which ensures that the target wind speed data corresponding to each target sampling point is smoother and more reasonable.
[0050] In one embodiment, determining the target equivalent wind speed of the impeller plane corresponding to the target impeller based on the target wind speed data corresponding to all the target sampling points includes: Determine the total area of the impeller plane corresponding to the target impeller based on the impeller radius; Determine the sampling point grid area corresponding to the target sampling point based on the preset sampling interval; The target equivalent wind speed of the impeller plane corresponding to the target impeller is determined based on the total area, the target wind speed data corresponding to all the target sampling points and the sampling point grid area.
[0051] Specifically, for the target sampling point , can be based on the impeller radius Determine the total area of the impeller plane corresponding to the target impeller , that is .
[0052] The sampling point grid area corresponding to the target sampling point can also be determined based on the preset sampling interval , the process can be expressed by the following formula: in, Indicates the horizontal axis interval in the preset sampling interval, Indicates the vertical axis interval in the preset sampling interval, for example, you can preset and Both are 10 meters.
[0053] Furthermore, based on the total area , the target wind speed data corresponding to all target sampling points and the sampling point grid area, determine the target equivalent wind speed of the impeller plane corresponding to the target impeller The target equivalent wind speed It can be determined by the following formula: in, Indicates target sampling points, represents the total number of target sampling points, Indicates The target wind speed data corresponding to the target sampling points.
[0054] In the above embodiment, the target equivalent wind speed is determined based on the total area of the impeller plane, the target wind speed data corresponding to the target sampling point, and the sampling point grid area. It can more accurately reflect the wind speed characteristics of the impeller plane, making it easier to accurately evaluate the power generation of the wind turbine.
[0055] The method for determining the equivalent wind speed of the impeller plane provided by the present invention inputs the wind farm data corresponding to the target impeller into the computational fluid dynamics software or the wind farm simulation software to obtain the simulated wind speed data output by the computational fluid dynamics software or the wind farm simulation software; based on the simulated wind speed data and the attribute parameters of the target impeller, the target equivalent wind speed of the impeller plane corresponding to the target impeller is determined. The simulated wind speed data obtained by the technical solution of the present invention through the fluid dynamics software not only considers the influence of the wind shear in the vertical direction on the wind speed, but also considers the influence of the wind direction deflection in the horizontal direction on the wind speed, and further determines the target equivalent wind speed of the impeller plane based on the simulated wind speed data and the attribute parameters of the target impeller, thereby improving the accuracy of the equivalent wind speed, thereby providing a good basis for accurately estimating the power generation.
