[0028] As the single-unit capacity of wind turbines continues to increase, the length of their blades also continues to increase. This long and flexible structure is more sensitive to wind loads, and its geometric shape will change significantly during operation. The traditional Prandtl tip-loss calculation method is based on the basic principles of fluid mechanics and has high theoretical accuracy, but it does not consider the influence of geometric shape changes on tip loss during the calculation process, making it difficult to accurately predict the tip loss of large-deformation blades.

[0029] To this end, the calculation method for the tip loss of a wind turbine blade provided in this application includes: obtaining the lift information of the wind turbine blade under the condition of no deformation; obtaining the lift information of the wind turbine blade under the deformed condition; correcting the lift information of the wind turbine blade under the deformed condition to obtain the corrected lift information; and determining the tip loss of the wind turbine blade under the deformed condition based on the lift information of the wind turbine blade under the condition of no deformation and the corrected lift information. This application corrects the lift information of the wind turbine blade under the deformed condition and solves the tip loss of the large-deformation blade based on the lift information of the wind turbine blade under the condition of no deformation and the corrected lift information, which can effectively improve the calculation accuracy of the lift information in the case of large geometric deformation of the blade, and then ensure the accuracy of the tip loss calculation, providing a solid and reliable basis for the evaluation of the aerodynamic performance of the wind turbine unit.

[0030] Refer to the appendix Figure 1 , Figure 1 which is a schematic diagram of the main steps of the calculation method for the tip loss of a wind turbine blade according to an embodiment of this application. As Figure 1 shown, the calculation method for the tip loss of a wind turbine blade in the embodiment of this application mainly includes the following steps S101 to S104.

[0031] Step S101: Obtain the lift information of the wind turbine blade under the condition of no deformation.

[0032] In this embodiment, the lift information of the wind turbine blade under the condition of no deformation refers to the lift information of each cross-section position of the wind turbine blade without considering the blade deformation.

[0033] Step S102: Obtain the lift information of the wind turbine blade under the deformed condition.

[0034] In this embodiment, the lift information of the wind turbine blade under the deformed condition refers to obtaining the lift information of each cross-section position of the wind turbine blade under the deformed condition by using the same blade parameters as in step S101 and considering the blade deformation.

[0035] Step S103: Correct the lift information of the wind turbine blade under the deformed condition to obtain the corrected lift information.

[0036] In this embodiment, in the case of large geometric deformation of the blade, the lift information of the wind turbine blade under the deformed condition is corrected to obtain the corrected lift information.

[0037] Step S104: Determine the tip loss of the wind turbine blade under the deformed condition based on the lift information of the wind turbine blade under the condition of no deformation and the corrected lift information.

[0038] Based on the method described in the above steps S101 to S104, the present application corrects the lift information of the fan blade under deformed conditions, and calculates the tip loss of the large-deformation blade based on the lift information under non-deformed conditions and the corrected lift information, which can more accurately reflect the tip loss of the blade in the deformed state and provide a reliable reference for the evaluation of the aerodynamic performance of the wind turbine.

[0039] The following further elaborates on steps S101 to S104 respectively.

[0040] Regarding step S101, in one embodiment, the obtaining of the lift information of the fan blade under non-deformed conditions includes: obtaining the blade parameters of the fan blade; performing a simulation on the fan blade based on the blade parameters of the fan blade to determine the lift information of the fan blade under non-deformed conditions.

[0041] Specifically, the blade parameters of the fan blade include information such as blade length, maximum chord length, and hub radius of the wind turbine. Assume the blade length of the fan blade is x meters, the maximum chord length is y meters, and the hub radius of the wind turbine is h meters. The fan blade under non-deformed conditions is as Figure 2 shown. Based on the blade parameters of the fan blade, without considering the blade deformation, a simulation is performed on the fan blade to determine the lift information of the fan blade under non-deformed conditions.

[0042] In one embodiment, the performing a simulation on the fan blade based on the blade parameters of the fan blade to determine the lift information of the fan blade under non-deformed conditions includes: performing three-dimensional modeling on the fan blade based on the blade parameters of the fan blade, setting the computational domain, and dividing the first computational domain grid; setting the simulation parameters, and performing a simulation on the first computational domain grid to determine the lift information of the fan blade under non-deformed conditions.

[0043] Specifically, based on the blade parameters of the fan blade, a simulation is performed on the fan blade to determine the lift information of the fan blade under non-deformed conditions. Specifically, the Gambit software is used to perform three-dimensional blade modeling on the fan blade. A cuboid region is set as the computational domain, with a width and height of 6x meters and a length of l meters (where l is much larger than x, indicating that the computational domain is large enough in the length direction to reduce the influence of boundary effects on the simulation results). The grid is divided within the computational domain to form the first computational domain grid.

[0044] Import the mesh of the first computational domain into ANSYS-Fluent software and set the simulation parameters. The simulation parameters include the angular velocity of the wind turbine rotor being ω degrees per minute, the incoming flow velocity being v m / s, with the direction perpendicular to the wind turbine plane. The two sides of the computational domain are respectively a velocity inlet and a pressure outlet, and the four sides are symmetry boundaries. Through CFD simulation, obtain the lift force L at the cross-section of the wind turbine blade at a distance r from the blade root under non-deformed conditions. 0 (r), and the first computational domain is as Figure 3 shown.

[0045] Regarding step S102, in one embodiment, obtaining the lift force information of the wind turbine blade under deformed conditions includes: obtaining the blade parameters and deformation parameters of the wind turbine blade; based on the blade parameters and deformation parameters of the wind turbine blade, simulating the wind turbine blade to determine the lift force information of the wind turbine blade under deformed conditions.

[0046] Specifically, the blade parameters of the wind turbine blade are the same as those in step S101. The deformation parameters of the wind turbine blade can be set such that deformation occurs at the position of the n% part starting from the blade tip. Considering the deformation of the blade, based on the blade parameters and deformation parameters of the wind turbine blade, simulate the wind turbine blade to determine the lift force information of the wind turbine blade under deformed conditions.

[0047] In one embodiment, based on the blade parameters and deformation parameters of the wind turbine blade, simulating the wind turbine blade to determine the lift force information of the wind turbine blade under deformed conditions includes: based on the blade parameters and deformation parameters of the wind turbine blade, performing 3D modeling on the wind turbine blade and setting the computational domain, and dividing the mesh of the second computational domain; setting the simulation parameters and simulating the mesh of the second computational domain to determine the lift force information of the wind turbine blade under deformed conditions.

[0048] Specifically, based on the blade parameters and deformation parameters of the wind turbine blade, perform 3D modeling on the wind turbine blade. And set a computational domain with the same size as the computational domain in step S101, and divide the mesh within this computational domain to form the mesh of the second computational domain.

[0049] Import the mesh of the second computational domain into ANSYS-Fluent software and set the simulation parameters, which are the same as the simulation parameters in step S101. Through CFD simulation, obtain the lift force L at the cross-section of the wind turbine blade at a distance r from the blade root under deformed conditions. 1 (r). The wind turbine blade under deformed conditions is as Figure 3 shown.

[0050] For step S103, in one embodiment, the lift information of the fan blade under the deformation condition is corrected to obtain the corrected lift information, including: considering the influence of the change of the projection area under the deformation condition on the tip loss, based on the angle between the blade tangent at a preset position of the fan blade under the deformation condition and the corresponding position of the fan blade under the non-deformation condition, the lift information of the fan blade under the deformation condition is corrected to obtain the corrected lift information.

[0051] Specifically, the theoretical calculation formula for the lift of the airfoil section of the blade section when it is not deformed is:

[0052] Where dL is the lift at the cross-sectional position, ρ is the air density, v is the incoming wind speed, and C l is the lift coefficient, c is the chord length of the airfoil, and dr is the length of the infinitesimal airfoil section at this section.

[0053] Considering the influence of the deformation of the fan blade, the tip part of the airfoil section deviates from the wind wheel plane, resulting in a change in the projection area when calculating the lift. Considering the influence of the projection area change on the tip loss under the deformation condition, the angle between the blade tangent at the distance r from the blade root after the blade deformation and the original blade is set to γ. Based on the angle γ between the blade tangent at the distance r from the blade root of the fan blade under the deformation condition and the corresponding position of the fan blade (i.e., the original blade) under the non-deformation condition, the calculation formula for the lift of the airfoil after the deformation section is obtained:

[0054] Among them, γ is the angle between the blade tangent line at the distance r from the blade root under the deformation condition and the original blade.

[0055] In order to eliminate the influence of the change of the projected area on the tip loss, it is necessary to convert the lift information L1(r) of the fan blade under the deformation condition. The calculation formula is: L' 1 (r) = L 1 (r) / cosγ

[0056] Among them, L' 1 (r) is the corrected lift information, L 1 (r) is the lift information of the fan blade under deformation condition.

[0057] For step S104, in one embodiment, determining the tip loss of the fan blade under the deformation condition based on the lift information of the fan blade under the non-deformation condition and the corrected lift information includes: determining an additional tip loss factor based on the lift information of the fan blade under the non-deformation condition and the corrected lift information; determining the tip loss factor of the fan blade under the deformation condition based on the additional tip loss factor.

[0058] Specifically, the tip loss in this embodiment refers to the tip loss factor.

[0059] Based on the lift information L 0 (r) of the wind turbine blade under the condition of no deformation and the corrected lift information L' 1 (r), the additional tip loss factor is determined, and the calculation formula is: α 附加 = L' 1 (r) / L 0 (r)

[0060] Based on the determined additional tip loss factor, the tip loss factor of the wind turbine blade under the deformation condition is determined.

[0061] In one embodiment, the determining the tip loss factor of the wind turbine blade under the deformation condition based on the additional tip loss factor includes: determining the Prandtl tip loss factor based on the Prandtl tip loss calculation method; and determining the tip loss factor of the wind turbine blade under the deformation condition based on the Prandtl tip loss factor and the additional tip loss factor.

[0062] Specifically, the Prandtl tip loss calculation method is used to calculate the tip loss factor under the condition of no deformation, denoted as α t . And based on the Prandtl tip loss factor and the additional tip loss factor, the tip loss factor of the wind turbine blade under the deformation condition is determined, and the calculation formula is as follows: F = α t ×α 附加

[0063] where F is the tip loss factor of the wind turbine blade under the deformation condition.

[0064] Refer to the appendix Figure 5 , Figure 5 is a schematic diagram of the detailed step flow of the calculation method of the tip loss of the wind turbine blade according to an embodiment of the present application; as Figure 5 shown, in this embodiment, the calculation method of the tip loss of the wind turbine blade includes the following steps:

[0065] Assume that the wind turbine blade is an ideal straight blade under the condition of no deformation, and obtain the Prandtl tip loss factor α t , and use the blade rotation CFD simulation to simulate the actual state of the blade in the flow field, and calculate the lift information of each cross-section position of the blade under the condition of no deformation through the simulation.

[0066] Considering the blade deformation situation, use the blade rotation CFD simulation to simulate the actual state of the blade in the flow field, and calculate the lift information of each cross-section position under the deformation condition through the simulation.

[0067] Considering the influence of the change in the projected area under the deformation condition on the tip loss, the lift information at each section position under the calculated deformation condition is corrected to obtain the corrected lift information.

[0068] According to the ratio of the corrected lift information to the lift information at each section position of the blade under the non-deformed condition, an additional tip loss factor is determined. Finally, based on the Prandtl tip loss factor α t and the additional tip loss factor, the total tip loss factor of the wind turbine blade under the deformation condition is determined.

[0069] The method for calculating the tip loss of a wind turbine blade considering the deformation condition provided by this application can correct the existing tip loss calculation method when the blade undergoes large geometric deformations, improve the accuracy of tip loss calculation, and provide a reliable reference for the assessment of the aerodynamic performance of wind turbines.
