[0001] Method for providing an adapted design of a generator

[0002] Technical area

[0003] The present invention relates to methods for providing an adapted design of a generator for a wind turbine. Furthermore, the present invention relates to a method for manufacturing such a generator.

[0004] State of the art

[0005] A generator for a wind turbine has mechanical and electrical interfaces for mechanically and electrically coupling the generator to other components of the wind turbine. If the power parameters of the wind turbine change, for example, the rotor diameter or the power output of the turbine, the generator must be adapted. Traditionally, such an adaptation of the generator also involves redesigning the mechanical and electrical interfaces and other components of the generator.

[0006] Description of the invention

[0007] The object of the present invention was to provide a method for providing an adapted design of a generator for a wind turbine, which enables flexible and cost-effective adaptation of the generator to changing power levels of the wind turbine. This object is achieved by a method for providing an adapted design of an adapted generator for a wind turbine with an adapted power level according to patent claim 1. A design of the generator can be a mechanical design, for example the dimensioning and materials of individual components of the generator and the generator as a whole. Alternatively or additionally, it can be an electromagnetic or electrical design, for example the electromagnetic and electrical dimensioning of individual components and the generator as a whole.The design may include the mechanical and alternatively or additionally electromagnetic / electrical design of interfaces of the generator for coupling the generator with other components of the wind turbine, for example a gearbox and an electrical energy converter.

[0008] The wind turbine can be of any design, for example a drag rotor or a lift rotor, whereby the wind turbine can have a horizontal or vertical axis of rotation. In one embodiment, the wind turbine is a lift rotor with a horizontal axis, three rotor blades, a mechanical gearbox, a generator, and an electrical energy converter. The generator can be a synchronous or asynchronous generator. The rotor diameter of the wind turbine can be more than 100 m, for example more than 150 m, in one embodiment between 150 m and 250 m. The power variable of the wind turbine can be a variable that describes the performance of the wind turbine. The power variable can be, for example, a rotor diameter or rotor radius.The power rating can also be the average or maximum electrical power available from the wind turbine. Other power ratings are also conceivable within the scope of the present invention. The wind turbine can be an integrated wind turbine, in which the output shaft of the gearbox simultaneously forms a rotor shaft of the generator. Alternatively, the wind turbine can also be a non-integrated design.

[0009] The method comprises providing an existing design of an existing generator for a wind turbine with an existing power rating. In other words, within the scope of this method step, an already designed and, for example, tested generator can be used. The existing generator can be designed for a specific wind turbine with a specific power rating, for example, for a wind turbine with a specific rotor diameter and a specific available electrical power. Furthermore, the method comprises comparing the adjusted power rating with the existing power rating.For example, during the comparison step, the rotor diameter and, alternatively or additionally, the available electrical power of the existing wind turbine are compared with the rotor diameter or the available electrical power of the adapted wind turbine. If no discrepancy between the power ratings is detected, no adjustment of the generator may be necessary. However, if a discrepancy between the existing and the adapted power ratings is detected in at least one of the power ratings, an adjustment to the generator design is required to adapt the generator to the adapted wind turbine.

[0010] Within the scope of the present invention, the generator is adapted by adapting a winding of a stator of the generator. For example, the adaptation takes place exclusively by adapting the stator winding. The stator winding can be the manner in which an electrical conductor is wound, whereby the conductor can have any cross-section. In addition to the winding, the stator can have a plurality of stator laminations, which can be stacked on top of one another in an axial direction of the stator. The axial direction of the stator and thus also the axial direction of the generator can coincide with a rotation axis of the generator. A radial direction of the stator and thus also the radial direction of the generator can be arranged perpendicular to the rotation axis and thus the axial direction of the generator.The stator laminations can be made of iron and have recesses for accommodating the stator winding. The plurality of stator laminations can be identical to one another, so that the stacked stator laminations can all have holes extending through the entire stator to accommodate the winding. A certain number of stator laminations can be combined to form a partial stack, wherein the stator can be formed by a plurality of such partial stacks, which can be arranged one behind the other in the axial direction of the generator. Each of the partial stacks can be formed by the same number of stator laminations. Cooling channels can be provided between the partial stacks. Alternatively, the stator laminations can also be combined to form a monolithic structure.The stator winding can be adapted in such a way that it can at least partially compensate for a difference in the electromagnetic operation of the generator caused by the deviation between the adapted power rating and the existing power rating. The winding can be adapted, for example, in such a way that the generator can continue to be operated with the same electrical interface and the same electrical energy converter. For example, despite the adapted power rating, the generator can continue to output essentially the same voltage as the existing generator by adapting the winding. Consequently, a method can be provided that enables simple and cost-effective adaptation of an existing generator to a wind turbine with adapted power data.At the same time, a large number of already designed and tested components of the generator can be reused within the framework of this design.

[0011] Within the scope of one embodiment, adapting the stator winding comprises adapting a length of the winding in an axial direction of the generator. For example, the length of the hole extending through the stator, which is formed by the stator laminations, can be increased or decreased. By adjusting the hole length, a length of the winding extending through the hole can also be adjusted. The hole length can be adjusted, for example, by adjusting the number of partial stacks of stator laminations. Alternatively or additionally, the number of turns of the stator winding can also be adjusted in a radial direction of the generator. The number of turns of the winding in the radial direction can, for example, be increased or decreased. For example, the number of turns per phase of the stator winding can be adjusted in the radial direction.

[0012] As described above, the adjusted power variable and the existing power variable can include a variable related to the rotor diameter of the wind turbine, for example, the rotor diameter itself or a variable that has a fixed relationship to the rotor diameter. If it is determined in the comparison step that the rotor diameter should be increased, then in this embodiment, the length of the winding is increased in the axial direction. An increased rotor diameter can be associated with a lower rotational speed of the rotor, which can lead to a reduction in the voltage delivered by the generator, for example, via the electrical interface described above to the electrical energy converter described above.To continue using the existing electrical interface and the existing electrical energy converter, the length of the stator winding can be increased in the axial direction to at least partially, for example, completely, compensate for the voltage drop. The number of turns in the radial direction per phase of the winding can remain constant within this embodiment.

[0013] As described above, the adjusted power variable and the existing power variable can comprise a variable related to the power of the wind turbine, for example, the available power itself or a variable that has a fixed relationship with the available power. If it is determined in the comparison step that the available power should increase, then, within the scope of this embodiment, the number of turns of the winding in the radial direction of the generator is reduced, for example, the number of turns per phase of the winding. At the same time, the length of the winding in the axial direction can be increased, for example, according to the previously described embodiment.Thus, the adapted generator with the existing electrical interface and the existing electrical energy converter can provide essentially the same voltage and absorb a greater torque due to the increased power.

[0014] In one embodiment, the existing design of the rotor of the existing generator is adopted unchanged for the adapted design. The rotor can have rotor laminations that can be designed in accordance with the above statements regarding the stator laminations. The rotor laminations can also be combined in partial stacks in accordance with the statements regarding the stator laminations. Alternatively, the rotor laminations can also be combined to form a monolithic structure. Provisions for accommodating permanent magnets can be provided in the rotor laminations. For example, the permanent magnets are distributed equidistant from one another along the circumference of the rotor. They can be provided on the radial outer surface or integrated into the rotor. The rotor can be arranged radially inside the stator.It can have a rotor interface via which the rotor can be mechanically connected to a gearbox of the wind turbine in a rotationally fixed manner. In this way, torque from the gearbox can be supplied to the generator via the rotor interface. In this embodiment, the design of the entire rotor, i.e. the rotor interface, the design and number of rotor laminations as well as the design and integration of the permanent magnets, can be adopted unchanged for the adapted design of the generator. In this embodiment, the adaptation of the stator winding can be carried out in such a way that the generator can also be used with the existing rotor when designed for an adapted power rating. For example, it is not necessary to produce new molds to manufacture adapted rotor laminations.

[0015] Alternatively or additionally, the design of the stator laminations of the existing generator can be adopted unchanged for the adapted design of the adapted generator. Only the number of sub-stacks can be adapted, for example, to adapt the length of the winding in the axial direction, as described above, whereby the stator laminations of the adapted design can be designed according to the stator laminations of the existing design. The design of the stator laminations can also be adopted if the number of turns of the winding in the radial direction of the generator is changed, for example by adjusting the cross-section of the conductor forming the winding. The adaptation of the stator winding can be carried out within the scope of this embodiment in such a way that the generator can also be used with the existing stator laminations when designed for an adapted power rating.For example, it is not necessary to produce new molds to produce customized stator laminations.

[0016] Alternatively or additionally, the design of a mechanical interface between the generator and a gearbox, for example the mechanical rotor interface described above and / or a mechanical stator interface for mechanically coupling the stator to the gearbox, can be adopted unchanged for the adapted design. Likewise, within the scope of this embodiment, the electrical interface for electrically coupling the generator to an electrical energy converter can be adopted unchanged for the adapted design. The electrical interface is designed, for example, for a specific voltage, a specific current and / or a specific frequency. The adaptation of the stator winding can be carried out within the scope of this embodiment in such a way that the generator can be used with the existing electrical interface even when designed for an adapted power rating.

[0017] Within the scope of one embodiment, the method comprises saving the adapted design on a storage medium, for example, a volatile or non-volatile memory. If the method is carried out with computer support and is therefore a computer-implemented method, the final adapted design can be saved, for example, as a data set. The data set embodies the result of the present method, i.e., the generator with the adapted design, which leads to the advantages described above. Alternatively or additionally, the method can comprise outputting control data to an external device. The control data can comprise manufacturing data for manufacturing the generator with the adapted design. The external device can therefore be a manufacturing device.Furthermore, the method may include manufacturing the generator with the adapted design, for example, based on the manufacturing data. Manufacturing may include manufacturing individual components and assembling the components to form a generator with the adapted design.

[0018] The present invention further relates to a data set containing data describing a generator with an adapted design according to one of the embodiments described above. The data set can be the data set that can be generated by storing the adapted design as described above. The data set can furthermore comprise instructions for producing the generator with the adapted design, for example by means of additive manufacturing. It can therefore be manufacturing data. Furthermore, the present invention relates to a generator with an adapted design that was manufactured according to the embodiment described above for manufacturing the generator.

[0025] Detailed description of embodiments

[0026] Figure 1 shows a diagram with existing power parameters of an existing wind turbine and several adapted power parameters of adapted wind turbines. The diameter D of the wind turbine rotor is plotted on the abscissa of the diagram. The power P of the wind turbine is plotted on the ordinate. Point (1) in the diagram indicates the power parameters of the existing wind turbine, namely the rotor diameter DB and the power PB of the existing wind turbine. Points (2), (3), and (4) in the diagram indicate power parameters of adapted wind turbines with adapted rotor diameters DA and / or adapted power PA, as described in detail below.

[0027] Figures 2 and 3 show the structure of a generator 1 for a wind turbine according to an embodiment of the present invention. Figure 2 shows the generator 1 in a longitudinal sectional view. Figure 3 shows the generator 1 in a cross-sectional view. The generator 1 comprises a stator 2 and a rotor 3, which are arranged coaxially to one another. In the present embodiment, the stator 2 is provided radially outside the rotor 3. The rotor 3 is rotatable about a central axis A of the generator 1 relative to the stator 2. The stator 2 and the rotor 3 are provided in a housing 4. In the torque transmission path from the rotor blades to the generator 1, a gearbox (not shown) is provided upstream of the generator 1. The stator 2 and the rotor 3 of the generator 1 are mechanically connected to the gearbox (not shown).For this purpose, the generator 1 has a mechanical rotor interface 5, to which the rotor 3 of the generator 1 is permanently connected in a rotationally fixed manner. Furthermore, the generator 1 comprises a.

[0028] Stator interface 6, via which the stator 2 is mechanically connected to the transmission via the housing 4. A torque can be supplied to the generator 1 via the rotor interface 5 from the transmission (not shown), which the generator 1 can convert into electrical energy. The generator 1 can output the electrical energy to an electrical energy converter via an electrical interface 7.

[0029] In the present embodiment, the stator 2 and the rotor 3 have stator and rotor laminations, respectively, which in the present embodiment are made of iron. In the present embodiment, the stator and rotor laminations are stacked one behind the other in the axial direction of the generator 1, i.e., in the direction of the central axis A. The stator and rotor laminations are each combined in the axial direction A to form partial stacks 11, between each of which a channel 12 is provided for cooling. In the present embodiment, the respective partial stacks 11 comprise a plurality of stator and rotor laminations stacked one on top of the other in the axial direction A, wherein in this case, each of the stacks 11 has the same number of stator and rotor laminations stacked one on top of the other. The larger the number of stacks 11, the greater the extension of the stator 2 and rotor 3 in the axial direction A.

[0030] In the present embodiment, provisions are provided in the rotor laminations for accommodating permanent magnets 8, some of which are shown as examples in Figure 3. As can be seen in Figure 3, the permanent magnets 8 are arranged on the radial outer side of the rotor 3. The rotor 3 comprises a plurality of such permanent magnets 8, which in the present embodiment are distributed equidistantly around the circumference of the rotor 3. The rotor laminations have recesses (not shown) for accommodating the permanent magnets 8.

[0031] A plurality of cutouts 9 for accommodating the stator winding 10 are also provided in the stator laminations, some of which are shown as examples in Figure 3. The cutouts 9 in the stator laminations together form holes extending in the axial direction A through the entire stator 2 for accommodating the stator winding 10. The stator winding 10 extends in the axial direction A from the beginning to the end of the stator 2, so that its length scales with the number of partial stacks 11 of rotor laminations. The more partial stacks 11 of rotor laminations are lined up one behind the other in the axial direction A, the longer the holes extending through the stator 2 in the axial direction A and the longer the stator winding 10 arranged in these holes. Furthermore, the stator winding 10 can be layered in the radial direction R of the generator 1.For this purpose, the recesses 9 in the stator laminations have a radial extension which allows several turns of the winding 10 to be stacked one above the other in the radial direction R in the recesses 9.

[0032] Figure 4a shows an existing generator 1 according to an existing design. The existing generator 1 is designed for an existing wind turbine with the power ratings shown in Figure 1 at point (1), i.e. for a wind turbine with a rotor diameter DB and a power PB. Figure 4a shows the rotor 3 with the permanent magnets 8. Arranged radially outside the rotor 3 is the stator 2, in which the recesses 9 extending through the entire stator 2 in the axial direction A are provided. As shown in the lower part of Figure 4a, the stator 2 of the existing generator 1 comprises sixteen partial stacks 11 arranged one behind the other in the axial direction A, between each of which a cooling channel 12 is provided. Each of the partial stacks 11 comprises a plurality of stator laminations stacked in the axial direction A, wherein all partial stacks 11 in the present case have the same number of stator laminations.Also visible in the lower part of Figure 4a is the stator winding 10, which extends in the axial direction A through the entire stator 2, i.e., through all sixteen partial stacks 11. Furthermore, the stator winding 10 of the existing generator 1 has a plurality of windings 13 stacked in the radial direction R, as shown in the upper part of Figure 4a. In the present embodiment, in each of the recesses 9, ten windings per phase of the stator winding 10 are stacked one above the other in the radial direction R.

[0033] Figure 5 schematically shows a flow diagram of a method for providing an adapted design of an adapted generator 1 according to an embodiment of the present invention. In a first step I, it is first checked whether the present method is suitable for determining an adapted design for a generator 1. For this purpose, within the scope of the present embodiment, it is determined whether the adapted design is compatible with the same number of pool pairs as the existing design of Figure 4a. The number of pool pairs can be determined by the highest rotational speed of the rotor 3 within the operating spectrum for which the present method is designed. Only if the test step I produces a positive result can an adapted design for a generator 1 be provided using the method of the present embodiment.The method shown in Figure 5 is based on the existing generator according to Figure 4a, which is why the method in step II now first comprises providing the design of the generator 1 shown in Figure 4a for the wind turbine with the power parameters according to point (1) in Figure 1.

[0034] In a subsequent step III, the adjusted power parameters of the adjusted wind turbine are determined. For example, if the wind turbine is to have the power parameters according to point (2) in Figure 1, i.e., the power PB as the existing wind turbine, but with a larger rotor diameter DA, these power parameters are identified in step III. The power parameters are identified accordingly if the wind turbine is to be operated with the power parameters according to point (3) or (4) in Figure 1. The adjusted power parameters of the adjusted wind turbine are then compared with the existing power parameters of the existing wind turbine in step IV.

[0035] Based on the comparison, the winding 10 of the stator 2 is now adjusted in the subsequent step V. In the present embodiment, this can be done in two different ways. Either the length of the winding 10 of the stator 2 in the axial direction A can be adjusted in a step V.1. In the present embodiment, this is done by, among other things, reducing or increasing the number of partial stacks 11 of the stator laminations. Alternatively, in a step V.2, the number of turns 13 per phase of the winding 10 in the radial direction R can be adjusted, i.e. reduced or increased. Depending on the comparison of the existing and the adjusted power variables in step IV, the winding 10 is adjusted in step V either by means of step V.1 and / or by means of step V.2.

[0036] If, for example, the adapted wind turbine is to be operated with the power ratings according to point (2) in Figure 1, the comparison in step IV shows that the wind turbine should have a larger rotor diameter DA, but the same power PB as the existing wind turbine. Such an adapted wind turbine can be used at a location with a lower average wind speed, although the power remains essentially the same. The rotor 3 of the generator 1 rotates at a lower speed than in the existing design, which is associated with a lower voltage output of the generator 1 via the electrical interface 7. This lower voltage would be associated with a higher current in the existing generator for the same power PB, for which the electrical interface 7 is not designed.In order to be able to reuse the electrical interface 7 from the existing generator 1 without adaptation, the axial length of the stator 2 is now increased in step V.1 by increasing the number of partial stacks 11 of stator laminations in the axial direction A. Figure 4b shows an adapted generator 1 for a wind turbine with the power ratings according to point (2) in Figure 1. As can be seen in Figure 4b, the winding 10 of the stator 2 has the same number of turns in the radial direction R as the existing generator 1 from Figure 4a, namely ten turns. However, the stator 2 of the generator 1 from Figure 4b comprises one partial stack 11 of stator laminations more than the existing generator 1 from Figure 4a, which results in a stator winding with a greater extension, i.e. length, in the axial direction A of the generator 1.

[0037] If, for example, the adapted wind turbine is to be operated with the power ratings according to point (3) in Figure 1, the comparison in step IV shows that the wind turbine should have the same rotor diameter DB but a higher power PA than the existing wind turbine. The rotor 3 of the generator 1 rotates at the same speed as in the existing design, but a higher torque occurs. This higher torque is compensated for in the present case by increasing the axial length of the stator 2 in step V.1 by increasing the number of partial stacks 11 of stator laminations in the axial direction A. Figure 4c shows an adapted generator 1 for a wind turbine with the power ratings according to point (3) in Figure 1. As can be seen in Figure 4c, the stator 2 of the generator 1 from Figure 4c has two partial stacks 11 of stator laminations more than the existing generator 1 from Figure 4a, i.e. a total of eighteen partial stacks 11.This results in a stator winding 10 with a greater extension, i.e., length, in the axial direction A of the generator 1. Thus, the higher torque can be compensated with the existing electrical and mechanical interfaces 5, 6, and 7 of the existing generator 1. At the same time, in step V.2, the number of turns 13 of the winding 10 in the radial direction R, which are connected in series per phase of the stator 2, is reduced to nine, as shown in Figure 4c. Thus, the voltage of the generator 1 can be maintained at approximately the same level as in the existing design.

[0038] Figure 4d shows an adapted generator 1 designed for an adapted wind turbine according to point (4) in Figure 1. In point (4), the comparison in step IV shows that, compared to the existing generator 1, both the rotor diameter DA and the power PA are higher than in the existing generator 1 from Figure 4a. To compensate, the axial length of the stator 2 is therefore increased in step V.1 by increasing the number of partial stacks 11 of stator laminations in the axial direction A to a total of nineteen partial stacks 11. At the same time, in step V.2, the number of turns 13 of the winding 10 in the radial direction R, which are connected in series per phase of the stator 2, is reduced to nine, as shown in Figure 4c.

[0039] In a subsequent step VI, the design of the rotor 2, i.e. the dimensions, materials and components, for example the number and design of the rotor laminations, are adopted unchanged from the existing generator 1 for the adapted generator 1. Likewise, the design of the stator laminations and sub-stacks 11 from the existing generator 1 are adopted unchanged for the adapted generator 1 in step VII. Only the number of sub-stacks 11 can be varied, as described above, whereby the design of the individual sub-stacks 11 corresponds to that of the existing generator 1. Finally, in step VIII, the design of the mechanical interface of the generator 1 to the gearbox, i.e. the rotor interface 5 and the stator interface 6, as well as the electrical interface 7 to the electrical energy converter are adopted unchanged from the existing generator 1 for the adapted generator 1.

[0040] In a subsequent step IX, the adapted design for the adapted generator 1 is saved on a storage medium. Subsequently, in a step X, the saved data is output in the form of control data to a device for manufacturing the adapted generator 1. The device manufactures the adapted generator 1 in step XI based on the control data.
