The singular terms "a" or "this" can also include plural forms.

[0028] As the capacity of individual wind turbine units continues to increase, their blade lengths also increase. This long, flexible structure is more sensitive to wind loads, and its geometry undergoes significant changes during operation. The traditional Prandtl tip loss calculation method is based on fundamental principles of fluid mechanics and has high theoretical accuracy. However, it does not consider the impact of geometric changes on tip loss during the calculation process, making it difficult to accurately predict the tip loss of blades with large deformations.

[0029] Therefore, the method for calculating the tip loss of wind turbine blades provided in this application includes: obtaining lift information of the wind turbine blade under undeformed conditions; obtaining lift information of the wind turbine blade under deformed conditions; correcting the lift information of the wind turbine blade under deformed conditions to obtain corrected lift information; and determining the tip loss of the wind turbine blade under deformed conditions based on the lift information of the wind turbine blade under undeformed conditions and the corrected lift information. This application corrects the lift information of the wind turbine blade under deformed conditions and solves for the tip loss of blades with large deformation based on the lift information of the wind turbine blade under undeformed conditions and the corrected lift information. This effectively improves the accuracy of lift information calculation even when the blade undergoes significant geometric deformation, thereby ensuring the accuracy of tip loss calculation and providing a solid and reliable basis for evaluating the aerodynamic performance of wind turbine units.

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

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

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

[0033] Step S102: Obtain the lift information of the wind turbine blades under deformation conditions.

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

[0035] Step S103: Correct the lift information of the wind turbine blades under the deformation conditions to obtain the corrected lift information.

[0036] In this embodiment, when the blade undergoes significant geometric deformation, the lift information of the wind turbine blade under deformation conditions is corrected to obtain the corrected lift information.

[0037] Step S104: Based on the lift information of the wind turbine blade under the undeformed condition and the corrected lift information, determine the tip loss of the wind turbine blade under the deformed condition.

[0038] Based on the methods described in steps S101 to S104 above, this application corrects the lift information of wind turbine blades under deformation conditions, and calculates the tip loss of blades with large deformation based on the lift information under no deformation conditions and the corrected lift information. This can more accurately reflect the tip loss of blades under deformation conditions and provide a reliable reference for the evaluation of the aerodynamic performance of wind turbine units.

[0039] Steps S101 to S104 will be further explained below.

[0040] Regarding step S101, in one embodiment, obtaining the lift information of the wind turbine blade under no deformation conditions includes: obtaining the blade parameters of the wind turbine blade; simulating the wind turbine blade based on the blade parameters of the wind turbine blade to determine the lift information of the wind turbine blade under no deformation conditions.

[0041] Specifically, the blade parameters of a wind turbine blade include blade length, maximum chord length, and wind turbine hub radius. Assuming the wind turbine blade length is x meters, the maximum chord length is y meters, and the wind turbine hub radius is h meters, the wind turbine blade under no deformation conditions is as follows: Figure 2 As shown, based on the blade parameters of the wind turbine blades, without considering blade deformation, a simulation is performed on the wind turbine blades to determine the lift information of the wind turbine blades under the condition of no deformation.

[0042] In one embodiment, the step of simulating the wind turbine blade based on the blade parameters of the wind turbine blade to determine the lift information of the wind turbine blade under no deformation conditions includes: performing a three-dimensional model of the wind turbine blade based on the blade parameters of the wind turbine blade, setting a computational domain, and dividing a first computational domain mesh; setting simulation parameters, simulating the first computational domain mesh, and determining the lift information of the wind turbine blade under no deformation conditions.

[0043] Specifically, based on the blade parameters of the wind turbine blades, simulations are performed to determine the lift information of the wind turbine blades under deformation-free conditions. Specifically, a 3D model of the wind turbine blades is created using Gambit software. 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). A mesh is then created within the computational domain to form the first computational domain mesh.

[0044] The first computational domain mesh was imported into ANSYS-Fluent software, and simulation parameters were set. These parameters included a rotor rotational angular velocity of ω degrees / minute, an incoming wind speed of v meters / second, and a direction perpendicular to the rotor plane. The computational domain was divided into a velocity inlet and a pressure outlet on either side, and a symmetrical boundary. Through CFD simulation, the lift L0(r) at a section r from the blade root of the wind turbine blade under undeformed conditions was obtained. The first computational domain is shown below. Figure 3 As shown.

[0045] Regarding step S102, in one embodiment, obtaining the lift information of the wind turbine blade under deformation conditions includes: obtaining the blade parameters and deformation parameters of the wind turbine blade; and simulating the wind turbine blade based on the blade parameters and deformation parameters to determine the lift information of the wind turbine blade under deformation 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 to the position where the blade deforms from the tip of the blade at a position of n%. Considering the deformation of the blade, the wind turbine blade is simulated based on the blade parameters and deformation parameters to determine the lift information of the wind turbine blade under deformation conditions.

[0047] In one embodiment, the step of simulating the wind turbine blade based on the blade parameters and deformation parameters of the wind turbine blade to determine the lift information of the wind turbine blade under deformation conditions includes: performing a three-dimensional model of the wind turbine blade based on the blade parameters and deformation parameters of the wind turbine blade, setting a computational domain, and dividing a second computational domain mesh; setting simulation parameters, simulating the second computational domain mesh, and determining the lift information of the wind turbine blade under deformation conditions.

[0048] Specifically, a three-dimensional model of the wind turbine blades is created based on their blade parameters and deformation parameters. A computational domain of the same size as the computational domain in step S101 is set up, and a mesh is generated within this computational domain to form a second computational domain mesh.

[0049] The second computational domain mesh was imported into ANSYS-Fluent software, and the simulation parameters were set to be the same as those in step S101. Through CFD simulation, the lift L1(r) at the section of the wind turbine blade at a distance r from the blade root under deformation conditions was obtained. The wind turbine blade under deformation conditions is shown below. Figure 3 As shown.

[0050] Regarding step S103, in one embodiment, the step of correcting the lift information of the wind turbine blade under the deformation condition to obtain the corrected lift information includes: considering the influence of the change in projected area under the deformation condition on the tip loss, and based on the angle between the blade tangent at a preset position of the wind turbine blade under the deformation condition and the corresponding position of the wind turbine blade under the non-deformation condition, correcting the lift information of the wind turbine blade under the deformation condition to obtain the corrected lift information.

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

[0052]

[0053] Where dL is the lift force at the cross-section, ρ is the air density, v is the incoming wind speed, and C l denoted as lift coefficient, c as airfoil chord length, and dr as the length of the micro-element airfoil segment at this cross-section.

[0054] Considering the influence of wind turbine blade deformation, the airfoil section at the blade tip deviates from the rotor plane, resulting in a change in the projected area when calculating lift. Taking into account the impact of this change in projected area on tip loss under deformation conditions, the angle between the blade tangent at a distance *r* from the blade root after deformation and the original blade is set as γ. Based on the angle γ between the blade tangent at a distance *r* from the blade root under deformation conditions and the corresponding position of the wind turbine blade under undeformed conditions (i.e., the original blade), the formula for calculating the lift of the deformed airfoil section is obtained as follows:

[0055]

[0056] Wherein, γ is the angle between the tangent of the blade at a distance r from the leaf root under deformation conditions and the original blade.

[0057] To eliminate the impact of projected area changes on tip loss, the lift information L1(r) of the wind turbine blades under deformation conditions needs to be recalculated. The calculation formula is as follows:

[0058] L'1(r)=L1(r) / cosγ

[0059] Where L'1(r) is the corrected lift information, and L1(r) is the lift information of the wind turbine blade under deformation conditions.

[0060] Regarding step S104, in one embodiment, determining the tip loss of the wind turbine blade under deformed conditions based on the lift information of the wind turbine blade under the undeformed condition and the corrected lift information includes: determining an additional tip loss factor based on the lift information of the wind turbine blade under the undeformed condition and the corrected lift information; and determining the tip loss factor of the wind turbine blade under deformed conditions based on the additional tip loss factor.

[0061] Specifically, in this embodiment, leaf tip loss refers to the leaf tip loss factor.

[0062] Based on the lift information L0(r) of the wind turbine blade under undeformed conditions and the corrected lift information L'1(r), the additional tip loss factor is determined, and the calculation formula is as follows:

[0063] α 附加 =L'1(r) / L0(r)

[0064] Based on the determined additional tip loss factor, the tip loss factor of the wind turbine blade under deformation conditions is determined.

[0065] In one embodiment, determining the tip loss factor of the wind turbine blade under deformation conditions 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 deformation conditions based on the Prandtl tip loss factor and the additional tip loss factor.

[0066] 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 Based on Prandtl's tip loss factor and the additional tip loss factor, the tip loss factor of the wind turbine blade under deformation conditions is determined, and the calculation formula is as follows:

[0067] F = α t ×α 附加

[0068] Where F is the tip loss factor of the wind turbine blade under deformation conditions.

[0069] See appendix Figure 5 , Figure 5 This is a detailed flowchart illustrating the steps of a method for calculating the tip loss of a wind turbine blade according to an embodiment of this application; as shown below. Figure 5 As shown, in this embodiment, the method for calculating the tip loss of the wind turbine blades includes the following steps:

[0070] Assuming the wind turbine blades are ideal, straight blades under no deformation conditions, obtain the Prandtl tip loss factor α. t We used blade rotation CFD simulation to simulate the actual state of the blade in the flow field, and calculated the lift information of each cross section of the blade under the condition of no deformation.

[0071] Considering blade deformation, blade rotation CFD simulation is used to simulate the actual state of the blade in the flow field, and the lift information of each cross-section position under deformation conditions is calculated through simulation.

[0072] Furthermore, considering the influence of the change in projected area under deformation conditions on tip loss, the lift information at each cross-sectional position under the calculated deformation conditions is corrected to obtain the corrected lift information.

[0073] Based on the ratio of the corrected lift information to the lift information at each cross-sectional position of the blade under undeformed conditions, the additional tip loss factor is determined. Finally, based on the Prandtl tip loss factor α... t The total tip loss factor of the wind turbine blade under deformation conditions is determined by the addition of the tip loss factor.

[0074] The tip loss calculation method for wind turbine blades considering deformation conditions provided in this application can correct existing tip loss calculation methods when the blade undergoes large geometric deformation, improve the accuracy of tip loss calculation, and provide a reliable reference for the aerodynamic evaluation of wind turbine units.
