Description

Technical Field

[0001] This invention relates to the field of high-temperature superconducting tape structure optimization technology, and in particular to a method, system, storage medium and device for optimizing the arrangement of high-temperature superconducting tapes. Background Technology

[0002] High-temperature superconducting tapes, as core materials for modern high magnetic field technology, play an irreplaceable role in key areas such as nuclear fusion devices, particle accelerators, magnetic resonance imaging, and superconducting power transmission. However, the critical current of high-temperature superconducting materials exhibits significant anisotropy, and its value is highly sensitive to the angle of the external magnetic field; this characteristic is known as "field angle dependence." Under complex operating conditions such as superconducting magnet systems, factors such as plasma disruption, power failure, and mechanical vibration can induce transient pulsed magnetic fields, harmonic fields, and random fluctuations in the magnetic field angle, causing drastic changes in the critical current of the superconducting tape. This not only seriously affects the operational stability of the magnet system but may also trigger local thermal runaway, endangering the safety of the entire device.

[0003] To suppress the field angle dependence of high-temperature superconducting tapes, existing technologies mainly employ two approaches: one is to introduce artificial pinning centers into the superconducting layer through nanoengineering, attempting to improve its anisotropy at the material level; the other is to design complex geometrically symmetrical structures inside the conductor to achieve dynamic cancellation of external magnetic fields. However, both methods have significant limitations: the fabrication process of artificial pinning centers is complex, the size and distribution of nanopillars are difficult to control precisely, and the chemical doping uniformity is poor, resulting in high costs and difficulty in achieving large-area, consistent production, thus limiting the actual improvement effect; while the approach relying on complex geometrically symmetrical structures is not only difficult to process and assemble, with gaps between tape groups that are difficult to eliminate, but also its magnetic field cancellation effect is significantly weakened under the action of strong external magnetic fields, failing to fundamentally solve the field angle dependence problem. Summary of the Invention

[0004] Based on this, it is necessary to propose an optimization method for the arrangement of high-temperature superconducting tapes to address the above problems.

[0005] A method for optimizing the arrangement of high-temperature superconducting tapes, the method comprising the following steps: Obtain a superconducting tape in a target scene, wherein the superconducting tape has a specific arrangement, number of conductor channels, and width; Determine the critical current of the superconducting tape in the target scenario; If the critical current of the superconducting tape in the target scenario does not meet the preset conditions, the superconducting tape is adjusted in the following ways: the superconducting tape is arranged in a vertical radial stacking manner; or, the number of conductor channels is increased while keeping the number of turns of the superconducting tape and the cable radius unchanged; or, the width of the superconducting tape is increased while keeping the conductor channels and the cable radius unchanged. Determine whether the critical current of the optimized superconducting tape meets the preset conditions. If it does, the optimization of the high-temperature superconducting tape arrangement is complete.

[0006] In the above scheme, determining whether the critical current of the optimized superconducting tape meets the preset conditions specifically includes: Measuring the critical current of the superconducting tape under different external magnetic field angles θ Calculate the average value I of the critical current at all angles. AVG Based on critical current The average value of the critical current I AVG Calculate the variance S of the critical current. 2 :

S represents the total number of angles measured. 2 Let V be the variance of the critical current; When the variance S of the critical current 2 When the current is less than a preset threshold, the critical current of the superconducting tape is determined to meet the preset conditions.

[0008] In the above scheme, the step of determining whether the critical current of the optimized superconducting tape meets the preset conditions also includes: Under a fixed magnetic field angle, the critical current value of the superconducting tape under different external magnetic field intensities was measured, and the critical current versus different external magnetic field intensities curves were plotted. Identify the inflection point of the critical current decrease from the curve of the critical current versus different external magnetic field intensities. The magnetic field intensity corresponding to this inflection point is the inflection point magnetic field Bc. When the inflection point magnetic field Bc reaches more than 1.2 times the maximum external magnetic field strength in the target application scenario, it is determined that the critical current of the superconducting tape meets the preset conditions.

[0009] In the above scheme, the number of conductor channels is increased sequentially according to the following formula:

[0010] in, The initial number of channels, The number of channels after the kth optimization, where k is a positive integer.

[0011] In the above scheme, the width of the superconducting tape is increased sequentially according to the following formula:

[0012] in, The initial width of the superconducting tape. Let be the width of the superconducting tape after the m-th optimization, where m is a positive integer.

[0013] In the above scheme, the arrangement of the superconducting tapes in a vertical radial stacking manner specifically includes: Multiple superconducting tapes are stacked along the radial direction of the conductor's cross-section to form tape groups, wherein the stacking direction of each tape group is perpendicular to the radial direction of the conductor's cross-section.

[0014] In the above scheme, the superconducting tape includes, but is not limited to, YBCO, and the YBCO maintains a superconducting state in a liquid nitrogen environment at -196℃.

[0015] This application also proposes a high-temperature superconducting tape arrangement optimization system, the system comprising: a parameter acquisition unit, a judgment unit, an optimization adjustment unit, and a verification unit; The parameter acquisition unit is used to acquire the superconducting tape in the target scene, wherein the superconducting tape has a specific arrangement, number of conductor channels and width; and to determine the critical current of the superconducting tape in the target scene. The judgment unit is used to determine whether the critical current of the superconducting tape in the target scene meets the preset conditions. The optimization and adjustment unit is used to adjust the superconducting tape if the critical current of the superconducting tape in the target scenario does not meet the preset conditions. The adjustment methods are: arranging the superconducting tape in a vertical radial stacking manner; or increasing the number of conductor channels while keeping the number of turns of the superconducting tape and the cable radius unchanged; or increasing the width of the superconducting tape while keeping the conductor channels and the cable radius unchanged. The verification unit is used to determine whether the critical current of the optimized superconducting tape meets the preset conditions. If it does, the optimization of the high-temperature superconducting tape arrangement is completed.

[0016] This application also proposes a readable storage medium storing a computer program, which, when executed by a processor, causes the processor to perform the following steps: Obtain a superconducting tape in a target scene, wherein the superconducting tape has a specific arrangement, number of conductor channels, and width; Determine the critical current of the superconducting tape in the target scenario; If the critical current of the superconducting tape in the target scenario does not meet the preset conditions, the superconducting tape is adjusted in the following ways: the superconducting tape is arranged in a vertical radial stacking manner; or, the number of conductor channels is increased while keeping the number of turns of the superconducting tape and the cable radius unchanged; or, the width of the superconducting tape is increased while keeping the conductor channels and the cable radius unchanged. Determine whether the critical current of the optimized superconducting tape meets the preset conditions. If it does, the optimization of the high-temperature superconducting tape arrangement is complete.

[0017] This application also proposes a computer device, including a memory and a processor, wherein the memory stores a computer program, and the computer program is executed by the processor in the following steps: Obtain a superconducting tape in a target scene, wherein the superconducting tape has a specific arrangement, number of conductor channels, and width; Determine the critical current of the superconducting tape in the target scenario; If the critical current of the superconducting tape in the target scenario does not meet the preset conditions, the superconducting tape is adjusted in the following ways: the superconducting tape is arranged in a vertical radial stacking manner; or, the number of conductor channels is increased while keeping the number of turns of the superconducting tape and the cable radius unchanged; or, the width of the superconducting tape is increased while keeping the conductor channels and the cable radius unchanged. Determine whether the critical current of the optimized superconducting tape meets the preset conditions. If it does, the optimization of the high-temperature superconducting tape arrangement is complete.

[0018] The embodiments of this invention offer the following advantages: By optimizing the spatial distribution of the superconducting tape within the cable cross-section, this invention improves magnetic field uniformity, significantly reducing the variance of the critical current fluctuation at different magnetic field angles and enhancing the magnetic field stability of the superconducting cable.

Finally, performance verification and iterative parameter adjustments ensure that the optimized superconducting cable meets robustness requirements in practical applications. This method does not require alteration of the superconducting material itself; performance improvement is achieved solely through structural optimization, demonstrating high engineering applicability and economic efficiency.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention; however, it will be apparent to those skilled in the art that the invention may be practiced without one or more of these details; in other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the invention. It should be understood that the invention can be practiced in different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the disclosure thorough and complete and to fully convey the scope of the invention to those skilled in the art.

[0023] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. When used herein, the singular forms “a,” “an,” and “the” are also intended to include the plural forms, unless the context clearly indicates otherwise. The terms “comprising” and / or “including,” when used in this specification, identify the presence of said features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups. When used herein, the term “and / or” includes any and all combinations of the associated listed items.

[0024] To fully understand the present invention, a detailed structure will be presented in the following description in order to illustrate the technical solution proposed by the present invention; optional embodiments of the present invention are described in detail below, however, in addition to these detailed descriptions, the present invention may have other embodiments.

[0025] like Figure 1 As shown, in one embodiment, a method for optimizing the arrangement of high-temperature superconducting tapes is provided. This method includes steps S101 to S104, which are detailed below: S101. Obtain the superconducting tape in the target scene. The superconducting tape has a specific arrangement, number of conductor channels, and width. This step lists three key structural parameters: arrangement, number of conductor channels, and strip width, which provide clear adjustment dimensions for subsequent optimization.

[0026] In some embodiments, the superconducting tape includes, but is not limited to, YBCO, which maintains a superconducting state in a liquid nitrogen environment at -196°C.

[0027] This invention applies to high-temperature superconducting tapes, such as yttrium barium copper oxide (YBCO). While these materials have achieved large-scale applications in the liquid nitrogen temperature range (-196°C), the significant anisotropy of their critical current—i.e., their strong dependence on the magnetic field direction—has been a core bottleneck restricting their stable operation in high-field magnets and other advanced applications. This method, through pure structural optimization, provides an engineering solution for YBCO tapes that systematically suppresses their inherent field angle dependence without complex material modification, demonstrating clear industrial relevance and extremely high practical value.

[0028] Furthermore, specifically defining the material as YBCO and specifying its liquid nitrogen operating environment fully utilizes the layered structure and excellent current-carrying potential of YBCO tape: YBCO tape is typically fabricated in thin strip form, and its layered structure is particularly suitable for geometric rearrangements such as vertical radial stacking. YBCO tape exhibits excellent current-carrying performance, and its current-carrying potential can be further maximized by increasing the number of channels and width, while structural optimization compensates for its anisotropy. Moreover, the thermal stability and mechanical properties of YBCO tape at liquid nitrogen temperatures allow for the aforementioned structural adjustments and encapsulation, ensuring the engineering feasibility of the method.

[0029] S102. Determine the critical current of the superconducting tape in the target scenario; By measuring the critical current, the current-carrying performance of current superconducting tapes in target scenarios can be quantitatively evaluated, thereby accurately determining whether they meet the working requirements and providing a basis for judgment on whether optimization is needed.

[0030] S103. If the critical current of the superconducting tape in the target scenario does not meet the preset conditions, the superconducting tape shall be adjusted in the following ways: the superconducting tape shall be arranged in a vertical radial stacking manner; or, the number of conductor channels shall be increased while keeping the number of turns of the superconducting tape and the cable radius unchanged; or, the width of the superconducting tape shall be increased while keeping the conductor channels and the cable radius unchanged. This is the core step and technical contribution of the present invention. It clarifies that the optimization process is initiated when performance is unsatisfactory, and provides three explicit and independent optimization paths: (1) Using a vertical radial stacking method: This method changes the spatial arrangement and improves the uniformity of the magnetic field or the current density by vertical radial stacking, thereby changing the most basic electromagnetic coupling relationship and fundamentally reducing the sensitivity of the strip to changes in the magnetic field angle. This is an optimization at the geometric structure level.

[0031] (2) Increase the number of conductor channels (while maintaining the number of turns and radius): This is achieved by increasing the number of conductor channels within a fixed space, directly increasing the total current-carrying cross-sectional area, and realizing internal magnetic field compensation to average and stabilize the critical current of each part, thereby suppressing the angular fluctuation of the overall performance. This is an optimization at the electromagnetic distribution level.

[0032] (3) Increase the width of the superconducting tape (while maintaining the channel and radius): This is achieved by increasing the width of a single tape, thereby increasing the cross-sectional area with a limited number of channels, and thus improving the current carrying capacity and anti-interference capability of a single tape, which directly enhances the overall performance robustness of the cable. This is an optimization at the material performance level.

[0033] Furthermore, the method utilizes a combination of three adjustment methods, allowing for selective and targeted application based on the specific cause of the initial problem—such as extreme sensitivity to angles, insufficient overall current carrying capacity, or severe internal interference—rather than requiring all three to be mechanically executed. This improves the efficiency and applicability of the method. This step, through targeted adjustments, optimizes the electromagnetic field distribution of the superconducting cable, reduces the impact of changes in the external magnetic field angle on the critical current, thereby effectively improving the critical current density and anti-interference capability of the superconducting tape and resolving the performance instability problem caused by field angle dependence in existing technologies.

[0034] like Figure 2 The diagram shows three schematic representations of high-temperature superconducting tape arrangements involved in this invention. (a) Structure 1: S1 represents the traditional parallel radial stacking method, serving as a benchmark for performance comparison; (b) Structure 2: S2 illustrates a hybrid stacking method; and (c) Structure 3: S3 presents the vertical radial stacking method used in this invention. Notably, in structure S3, the stacking direction of each tape group is strictly perpendicular to the radial direction of the conductor cross-section. This unique geometric configuration is a key design feature for reducing the dependence of magnetic field angle in this method. Through the visual comparison of these three structures, the innovative breakthrough of this invention in basic arrangement methods can be clearly demonstrated.

[0035] like Figure 3The diagrams show three configurations in the conductor channel number optimization process. (a) Four channels: T1 shows the basic structure of four channels; six channels: (b) T2 shows the arrangement change after increasing the number of channels to six; eight channels: (c) T3 further shows the dense arrangement of eight channels. From T1 to T3, it is evident that the distribution density of current-carrying units gradually increases in the circumferential direction. This systematic increase in the number of channels effectively disperses and averages the influence of magnetic field angle changes on individual current-carrying units, intuitively explaining the technical principle of increasing the number of conductor channels to reduce field angle dependence in this method, and providing a clear visual basis for understanding the physical mechanism of channel number optimization.

[0036] like Figure 4 The diagram illustrates the optimization of superconducting tape width. (a) D1 corresponds to a width of 2 mm, (b) D2 corresponds to a width of 4 mm, and (c) D3 corresponds to a width of 6 mm. The diagram shows that while maintaining the total current-carrying area, as the width increases, the number of tapes decreases accordingly, while the current-carrying cross-sectional area of ​​a single tape significantly increases. This width optimization not only directly increases the overall critical current of the superconducting cable, but more importantly, the wider tape exhibits lower sensitivity to changes in local magnetic fields. Its enhanced anti-interference capability is visually demonstrated in the diagram, fully illustrating the path to improving stability by increasing the tape width.

[0037] In some embodiments, the number of conductor channels is increased sequentially according to the following formula:

[0038] in, The initial number of channels, The number of channels after the kth optimization, where k is a positive integer.

[0039] This formula clearly defines the increase in the number of channels in each iteration of optimization, providing a clear mathematical basis and operability for the optimization process. It avoids blind parameter adjustments, thereby improving the controllability and accuracy of the optimization process. By setting a fixed growth factor of 0.5k, it is possible to gradually increase the number of conductor channels to improve the critical current and reduce field angle dependence, while avoiding material waste, structural complexity, or insufficient space caused by a sudden increase in the number of channels. This achieves an optimal balance between performance improvement, manufacturing cost, and structural feasibility.

[0040] In some embodiments, the width of the superconducting tape is increased sequentially according to the following formula:

[0041] in, The initial width of the superconducting tape. Let be the width of the superconducting tape after the m-th optimization, where m is a positive integer.

[0042] Wide-width strips have a lower aspect ratio than narrow-width strips, and are less sensitive to changes in magnetic field angle. Optimizing the width using this formula can further reduce the magnitude of the critical current change with the magnetic field angle, thereby reducing field angle dependence and enhancing the robustness of the cable in complex magnetic field environments.

[0043] In some embodiments, the superconducting tapes are arranged in a vertically radial stacking manner, specifically including: Multiple superconducting tapes are stacked along the radial direction of the conductor's cross-section to form tape groups, with the stacking direction of each tape group perpendicular to the radial direction of the conductor's cross-section.

[0044] By making the stacking direction of each strip group perpendicular to the radial direction of the conductor cross section, the orientation of the strip in the cable cross section is changed, which can effectively disperse or cancel the negative impact of magnetic fields in different directions on the critical current, significantly reduce the field angle dependence of the superconducting strip, and make the performance of the cable more uniform under magnetic fields at different angles.

[0045] S104. Determine whether the critical current of the optimized superconducting tape meets the preset conditions. If it does, the optimization of the high-temperature superconducting tape arrangement is complete.

[0046] By verifying the optimized performance, it can be ensured that the adjusted superconducting tape arrangement structure has indeed achieved the expected performance indicators, reduced the field angle dependence of the superconducting tape and improved the stability of the equipment, thus ensuring the reliability of the optimization scheme.

[0047] In some embodiments, determining whether the critical current of the optimized superconducting tape meets a preset condition specifically includes: Measuring the critical current of superconducting tapes under different external magnetic field angles θ Calculate the average value I of the critical current at all angles. AVG Based on critical current The average value of the critical current I AVG Calculate the variance S of the critical current. 2 :

[0048] in, external magnetic field angle The critical current below, This is the average value of the critical current at all angles. S represents the total number of angles measured. 2 Let V be the variance of the critical current; When the variance of the critical current S 2 When the current is less than a preset threshold, the critical current of the superconducting tape is determined to meet the preset conditions.

[0049] Specifically, by introducing the variance S of the critical current... 2 As an evaluation index, it enables the mathematical quantification of the performance fluctuation of superconducting tapes under different magnetic field angles, and the variance S of the critical current. 2 The smaller the value, the smaller the fluctuation of the critical current with respect to angle, thus enabling a more accurate and objective evaluation of the field angle dependence of the superconducting tape. Secondly, the variance S of the critical current... 2 Using a preset threshold as the criterion for completion of optimization provides a clear and quantifiable stopping standard for the layout optimization process. This eliminates reliance on human experience in the optimization method, ensuring the reliability and consistency of the optimization results and facilitating automated control. Finally, the superconducting tape layout structure selected through this verification method ensures relatively consistent critical current performance under different magnetic field angles, thereby significantly improving the stability of superconducting cables operating in complex magnetic field environments and effectively reducing performance fluctuations and quench risk caused by changes in magnetic field angle.

[0050] In some embodiments, determining whether the critical current of the optimized superconducting tape meets the preset conditions further includes: Under a fixed magnetic field angle, the critical current value of the superconducting tape under different external magnetic field intensities was measured, and the critical current versus different external magnetic field intensities curves were plotted. Identify the inflection point of the critical current decrease from the curve of critical current versus different external magnetic field intensities. The magnetic field intensity corresponding to this inflection point is the inflection point magnetic field Bc. When the inflection point magnetic field Bc reaches more than 1.2 times the maximum external magnetic field strength in the target application scenario, it is determined that the critical current of the superconducting tape meets the preset conditions.

[0051] Specifically, by measuring the inflection point magnetic field Bc, the withstand capability and performance margin of the optimized superconducting cable in strong magnetic field environments can be quantitatively evaluated, ensuring that it can maintain its superconducting state even when faced with the maximum magnetic field impact in practical applications. Furthermore, setting the inflection point magnetic field Bc to be 1.2 times the maximum external magnetic field strength of the target scenario provides necessary safety redundancy for the superconducting equipment, greatly enhancing the system's robustness and effectively avoiding unexpected quench failures caused by magnetic field strength fluctuations. This ensures the long-term safe and stable operation of the superconducting magnet or cable system under complex operating conditions.

[0052] In summary, the field angle dependence of superconducting tapes is significantly affected by three key parameters: the arrangement of the tapes, the number of conductor channels, and the width of the superconducting tape. The specific mechanisms are as follows: First, the arrangement is a fundamental structural factor determining the field angle dependence. In this invention, a vertical radial stacking method is adopted, meaning the stacking direction of the strip groups is perpendicular to the radial direction of the conductor cross-section. This unique geometric layout alters the relative angle between the superconducting strip surface and the applied magnetic field. Since high-temperature superconducting materials (such as YBCO) have a higher critical current under the magnetic field component parallel to the strip surface, but a sharp decrease under the perpendicular component, vertical radial stacking ensures that the strip plane primarily senses the magnetic field in the vertical direction, thus avoiding the most unfavorable magnetic field angle. This structure effectively disperses the concentrated impact of the magnetic field on individual strips, significantly reducing the fluctuation amplitude of the critical current as a function of the magnetic field angle, thereby reducing the field angle dependence at its source.

[0053] Secondly, the increased number of conductor channels further weakens the field angle dependence through statistical averaging. Increasing the number of conductor channels means distributing more superconducting paths across the cable cross-section, resulting in differences in the angle and intensity of the magnetic field experienced by the superconducting tape at different spatial locations. When multiple channels operate in parallel, the critical current of the overall cable is the sum of the critical currents of each channel. This macroscopic current-carrying capacity, to some extent, smooths out the performance troughs of a single tape at specific unfavorable angles, making the overall cable's performance more uniform and robust across different angles.

[0054] Finally, increasing the width of the superconducting tape reduces angle sensitivity by altering its aspect ratio. Wider tapes have larger geometric dimensions, resulting in a more complex magnetic field vector distribution on the surface when the external magnetic field angle changes, thus weakening the equivalent anisotropy effect. Compared to narrow tapes, wider tapes are less sensitive to changes in magnetic field angle, and the attenuation trend of the critical current at different angles is more gradual. Therefore, increasing the tape width helps improve the cable's adaptability to complex magnetic field environments, further reducing the overall field angle dependence.

[0055] This invention effectively disperses the influence of magnetic fields on superconducting materials by optimizing the arrangement structure of superconducting tapes, combining key methods such as vertical radial stacking, increasing the number of conductor channels, and increasing the tape width. This significantly reduces the sensitivity of the critical current to changes in the magnetic field angle, i.e., field angle dependence. At the same time, this method uses the variance of the critical current and the inflection point magnetic field Bc as quantitative verification indicators to ensure that the optimized structure has high stability and sufficient safety margin under magnetic fields of different angles and intensities. Thus, it greatly improves the current carrying capacity and operational stability of superconducting devices without the need for complex material modification processes.

[0056] This application also proposes a high-temperature superconducting tape arrangement optimization system, which includes: a parameter acquisition unit, a judgment unit, an optimization adjustment unit, and a verification unit; The parameter acquisition unit is used to acquire the superconducting tape in the target scene. The superconducting tape has a specific arrangement, number of conductor channels, and width; and to determine the critical current of the superconducting tape in the target scene. The judgment unit is used to determine whether the critical current of the superconducting tape in the target scene meets the preset conditions.

The verification unit is used to determine whether the critical current of the optimized superconducting tape meets the preset conditions. If it does, the optimization of the high-temperature superconducting tape arrangement is completed.
