[0026] As an example, the environmental turbulence correction method for a wind turbine generator set according to an exemplary embodiment of the present disclosure may be executed by an electronic device with data processing capabilities, for example, a terminal (such as a personal notebook, a desktop, etc.), a server (such as an independent server, a server cluster, a cloud platform, etc.), or a wind farm controller or a unit controller. The present disclosure does not limit this.

[0027] Reference Figure 1In step S101, the sectors where each unit in the wind farm is located are determined from multiple sectors of the target unit.

[0028] The wind farm is the wind farm where the target unit is located. The target unit can be any unit in the wind farm, and the above-mentioned units are the other units in the wind farm except the target unit.

[0029] As an exemplary embodiment, the above-mentioned wind farm is a large wind farm. As an example, the design standard IEC 61400-1 for wind turbines defines a large wind farm as follows: 1) from the wind turbine under consideration to the edge of the wind farm, the number of wind turbines is not less than 5; 2) the spacing between rows perpendicular to the incoming wind direction is less than 3D (D is the diameter of the turbine rotor).

[0030] As an exemplary embodiment, the environmental turbulence correction method for a wind turbine generator set according to an exemplary embodiment of the present disclosure may also include: sector division for the target unit. As an example, a 360-degree circular angle with the target unit as the center may be divided (e.g., evenly divided) into a plurality of sectors, for example, it may be divided into 4 sectors, each sector containing 90°. It should be understood that more or fewer sectors may be obtained according to actual needs. In addition, as an example, sector division may be performed according to the dominant wind energy direction of the target unit to try to assign the dominant wind energy direction to the same sector.

[0031] As an exemplary embodiment, Figure 2 As shown, step S101 may include: steps S201 to S203.

[0032] Reference Figure 2 In step S201, the coordinates of the positions of each unit in a Euclidean coordinate system with the position of the target unit as the origin are determined.

[0033] As an exemplary embodiment, the geographic coordinates of the target unit may be , the geographic coordinates of the jth unit other than the target unit can be , in the Euclidean coordinate system with the geographic coordinates of the target unit as the origin, the coordinates of the jth unit can be Here, j is an integer greater than 0 and less than the total number of units in the wind farm.

[0034] In step S202, the coordinates of each unit in the Euclidean coordinate system are converted into coordinates in the polar coordinate system.

[0035] As an exemplary embodiment, the Euclidean coordinate system with the geographic coordinates of the target unit as the origin can be converted into a polar coordinate system, and the coordinates of other units in the polar coordinate system can be obtained. As an example, for the jth unit other than the target unit, the coordinates in the polar coordinate system ( , ) can be:

[0036] (1)

[0037] in, represents the radius coordinate, Represents angular coordinates.

[0038] In step S203, the sectors where the various units are located are determined based on the coordinates of the various units in the polar coordinate system and the ranges of the various sectors of the target unit.

[0039] As an exemplary embodiment, the sector to which the polar angle corresponding to each unit belongs can be determined based on the polar angle of each unit in the polar coordinate system and the angular range boundary of each sector in the polar coordinate system, thereby determining the sector in which each unit is located.

[0040] return Figure 1 In step S102, based on the position information of the units in each sector relative to the target unit, a virtual machine unit arrangement array with equal row spacing and equal column spacing in each sector is constructed.

[0041] Specifically, for each sector, based on the position information of the units in the sector relative to the target unit, a virtual machine group arrangement array with equal row spacing and equal column spacing (that is, a virtual machine group arrangement array with equal density and regular arrangement) is constructed for the sector. The equal row spacing means that the distance between rows in the virtual machine group arrangement array is equal, and the equal column spacing means that the distance between columns in the virtual machine group arrangement array is equal.

[0042] It should be understood that the virtual unit arrangement array of each sector is virtually constructed for the purpose of performing environmental turbulence correction for the target unit, and is not the actual unit arrangement in the wind farm. In fact, the virtual unit arrangement array of the sector is different from the actual unit arrangement in the sector. Specifically, the total number of virtual units in the virtual unit arrangement array of the sector ( ) may not be equal to the total number of actual units in the sector (N), and the specific layout may also be quite different.

[0043] As an exemplary embodiment, the position information of the units in the sector relative to the target unit may include: the coordinates of each unit in the sector in a Euclidean coordinate system with the position of the target unit as the origin.

[0044] As an exemplary embodiment, the virtual machine group arrangement array of the Ith sector is a rectangular array with P rows and Q columns of virtual machine groups, the rows of the rectangular array are perpendicular to the axis of the Ith sector, and the columns of the rectangular array are parallel to the axis. Here, I is an integer greater than 0 and less than or equal to the total number of sectors of the target group, that is, the Ith sector is any sector.

[0045] As an example, the axis of the Ith sector may be the bisector of the Ith sector.

[0046] As an example, the angle (ie, azimuth) corresponding to the axis of the Ith sector may be , the analytical expression of the axis of the Ith sector can be:

[0047] (2)

[0048] (3)

[0049] Among them, y represents the ordinate, k represents the slope, and x represents the abscissa.

[0050] As an example, the values ​​of P and Q satisfy the constraints determined based on N, where N represents the total number of units (actual units rather than virtual units) in the Ith sector. As an example, the constraints may include: P Q (P Q= ) is greater than or equal to N; and / or, the smaller of P and Q is greater than or equal to P The difference between Q and N. For example, constraints may include: , .

[0051] As an exemplary embodiment, the position coordinates of the units in the first sector are The first-order moment of is related to the position coordinates of the virtual machine group in the virtual machine group arrangement array of the I-th sector The first-order moment of is equal; the second-order moment of the position coordinates of the unit in the I-th sector is equal to the second-order moment of the position coordinates of the virtual machine group in the virtual machine group arrangement array of the I-th sector.

[0052] The first-order moment of the position coordinates of the unit in the Ith sector can be:

[0053] (4)

[0054] The second-order moment of the position coordinates of the unit in the Ith sector can be:

[0055] (5)

[0056] The first-order moment of the position coordinates of the virtual machine group in the virtual machine group arrangement array of the Ith sector can be:

[0057] (6)

[0058] The second-order moment of the position coordinates of the virtual machine group in the virtual machine group arrangement array of the Ith sector can be:

[0059] (7)

[0060] in, , represents the position coordinates of the i-th unit in the i-th sector, , Representing the position coordinates of the i-th virtual machine group in the virtual machine group arrangement array of the i-th sector, the first-order and second-order isometric equations are:

[0061] (8)

[0062] As an exemplary embodiment, the position coordinates of the virtual machine group located in the pth row and the qth column in the virtual machine group arrangement array of the 1st sector are: the solution of the first straight line equation and the second straight line equation. The first straight line equation is based on the value of q, the column spacing of the virtual machine group arrangement array of the 1st sector , the azimuth angle corresponding to the axis; the second straight line equation is based on the value of p, the row spacing of the virtual machine group arrangement array of the Ith sector , and the azimuth angle corresponding to the axis, where p is an integer greater than 0 and less than or equal to P, and q is an integer greater than 0 and less than or equal to Q.

[0063] It should be understood that each virtual machine group in the virtual machine group arrangement array of the first sector corresponds to a first straight line equation and a second straight line equation, and different virtual machine groups correspond to different first straight line equations and / or second straight line equations. In fact, for the first sector, a total of Q first equations and P second equations are constructed, all the first equations form a cluster of straight lines, all the second equations form a cluster of straight lines, and the two clusters of straight lines form a total of P Q intersection points , these intersection points are the position coordinate points of the virtual machine groups in the virtual machine group arrangement array.

[0064] As an example, the first equation and the second equation may be as follows, the first equation may be in the form of formula (9), and the second equation may be in the form of formula (10); or, the first equation may be in the form of formula (11), and the second equation may be in the form of formula (12):

[0065]

[0066]

[0067] The k in formulas (9)-(12) is the same as the k in formulas (2) and (3).

[0068] Based on the above embodiment, the unknowns P, Q, and equation, calculate P, Q, and .

[0069] In addition, as an exemplary embodiment, the environmental turbulence correction method of the wind turbine generator set according to the exemplary embodiment of the present disclosure may further include: based on the calculated P, Q, and , determine and output the specific location coordinates of each virtual machine group in the virtual machine group arrangement array of the Ith sector.

[0070] In step S103, the turbulence correction amount of each sector is determined based on the virtual machine group arrangement array of each sector.

[0071] The turbulence correction amount of each sector is used to correct the environmental turbulence data when the incoming wind direction belongs to the sector, so as to obtain environmental turbulence data that is closer to the actual situation. As an exemplary embodiment, the determined turbulence correction amount can correct the deviation between the actual environmental turbulence of the unit caused by the high wind field effect and the calculated environmental turbulence. As an exemplary embodiment, the determined turbulence correction amount can be a correction amount for correcting the parameter of the environmental turbulence standard deviation.

[0072] As an exemplary embodiment, step S103 may include: determining the turbulence correction amount of each sector based on the row spacing and column spacing of the virtual machine assembly arrangement array of each sector. Further, as an example, the turbulence correction amount of each sector may be determined based on the row spacing and column spacing of the virtual machine assembly arrangement array of each sector, the thrust coefficient of the target unit, and the wind speed at the hub height of the target unit.

[0073] As an example, when the determined turbulence correction amount is a correction amount for correcting the parameter of the environmental turbulence standard deviation, the environmental turbulence standard deviation increased due to the high wind field effect in the first sector of the target unit can be determined by the following formula: (i.e., turbulence correction):

[0074] (13)

[0075] in, represents the wind speed at the hub height of the target unit, represents the thrust coefficient of the target unit, represents the column spacing of the virtual machine group arrangement array of the Ith sector, Indicates the row spacing of the virtual machine group arrangement array of the I-th sector.

[0076] In step S104, the ambient turbulence of the target unit (eg, ambient turbulence data calculated based on wind measurement data) is corrected based on the turbulence correction amount of each sector.

[0077] As an exemplary embodiment, step S104 may include: based on the turbulence correction amount of each sector, correcting the environmental turbulence data of the target unit calculated based on the wind measurement data to obtain environmental turbulence data that is more in line with the actual situation.

[0078] As an exemplary embodiment, step S104 may include: determining the target sector to which the incoming wind direction of the target unit belongs from multiple sectors of the target unit; and correcting the ambient turbulence of the target unit using the turbulence correction amount of the target sector.

[0079] As an exemplary embodiment, when the determined turbulence correction amount is a correction amount for correcting the parameter of the ambient turbulence standard deviation, the ambient turbulence of the target unit can be corrected by the following formula:

[0080] (14)

[0081] in, represents the standard deviation of the ambient turbulence to be corrected (for example, the standard deviation of the ambient turbulence calculated based on wind measurement data), represents the corrected standard deviation of ambient turbulence, Indicates the turbulence correction for the target sector.

[0082] The present application provides a method for correcting environmental turbulence in a large wind farm based on a virtually constructed arrangement of units with equal density. On the one hand, the correction method is not only applicable to wind farms with regularly arranged units, but also to wind farms with irregularly arranged units. It has a wider range of applicable scenarios and can cover wind farms with irregular arrangements with isolated points. On the other hand, it can provide more realistic environmental turbulence data for accurate calculation of wind farm power generation and safety verification of wind turbines, thereby avoiding potential unit load safety issues caused by inaccurate environmental turbulence data.
