Description

Technical Field

[0001] The present invention relates to the technical field of wind field simulation, and in particular to a wind field device and a complex wind field generation method. Background Art

[0002] Wind field simulation technology has widespread applications in aerospace, construction, transportation, and new energy, and plays a crucial role in the development of the wind power industry. Traditional wind field simulation equipment primarily relies on wind tunnel systems to generate and control airflow. Traditional wind tunnels generate stable airflow through fan-driven systems, and utilize components such as guide vanes and honeycomb rectifiers to rectify and accelerate the airflow, creating a relatively uniform and controllable flow field environment.

[0003] However, real wind fields involve not only horizontal flow but also vertical motion (such as updrafts and downdrafts), vortex structures, and turbulent characteristics that evolve over time. Traditional wind tunnels rely on fans as their power source. However, the speed regulation of fans has a certain inertia, resulting in a relatively slow change in wind speed. This makes it difficult to simulate the sudden and rapidly changing wind conditions found in nature, such as gusts, storms, or sudden changes in wind direction.

[0004] In summary, it is difficult to achieve dynamic and non-uniform wind field simulation in existing technologies. Therefore, existing technologies are difficult to meet the growing technical demand for dynamic and non-uniform wind field simulation in fields such as aerospace, construction engineering, transportation and new energy. Summary of the Invention

[0005] The main purpose of the present invention is to propose a wind field device and a complex wind field generation method, which can realize dynamic and non-uniform wind field simulation and realize wind direction control in the vertical direction.

[0006] To achieve the above objectives, some embodiments of the present invention provide a wind farm device, comprising: Main structure; The bearing structure is connected to the main structure, and the bearing structures are distributed at intervals along the vertical direction; A wind farm unit is connected to one side of the supporting structure in the vertical direction.

Along the airflow direction of the wind turbine, the supporting structure has a first side and a second side distributed in sequence, and the guide plate is located on at least a portion of the second side of the supporting structure; The guide plate is configured to be able to rotate around a horizontal direction to adjust the direction of the airflow.

[0007] In some embodiments, the edge of the guide plate close to the wind farm unit is the first edge, and the wind farm equipment includes a second controller, which is connected to the guide plate to drive the guide plate to rotate around the first edge. The rotation angle θ of the guide plate relative to the supporting structure satisfies: 0°≤θ≤45°.

[0008] In some embodiments, the first controller is configured to adjust the wind speed of the wind farm unit so that the wind farm equipment can complete at least one of gust simulation, gust simulation, wind shear simulation, and turbulence simulation.

[0009] In some embodiments, the rectifying assembly includes an outer shell and a baffle. Along the airflow direction, the outer shell has a hollow area running through it, and the baffle is provided in the hollow area.

[0010] In some embodiments, a cross section of the outer shell cut by a vertical plane is circular, the rectifying assembly includes a plurality of baffles, and the cross sections of the plurality of baffles cut by the vertical plane all intersect at the center of the circle.

[0011] In some embodiments, the wind farm units are evenly distributed along the horizontal direction; and / or, Along the vertical direction, the wind farm units are evenly distributed.

[0012] In some embodiments, along the vertical direction, between two adjacent supporting structures, the wind farm units are stacked in at least two layers along the vertical direction.

[0013] In some embodiments, the main structure includes supporting side beams arranged opposite to each other in a horizontal direction, the load-bearing structure is plate-shaped, and the load-bearing structure is detachably connected between the two oppositely arranged supporting side beams.

[0014] In some embodiments, along the airflow direction, the supporting side beam protrudes from the wind farm unit; and / or, In the opposite direction of the airflow, the supporting beam protrudes from the wind field unit.

[0015] In some embodiments, the main structure includes a supporting top beam and a supporting bottom beam relatively distributed in a vertical direction, the supporting top beam, the supporting side beams and the supporting bottom beam jointly enclose an airflow channel, and the wind farm unit is arranged in the airflow channel; Among them, along the airflow direction, the supporting top beam, supporting side beams and supporting bottom beam all protrude from the wind farm unit, and / or along the opposite direction of the airflow direction, the supporting top beam, supporting side beams and supporting bottom beam all protrude from the wind farm unit.

[0016] In some embodiments, the wind farm equipment further includes partitions, which are connected to the main structure and arranged at intervals in the horizontal direction. The partitions and the supporting structure intersect to form a storage bin, which is used to accommodate the wind turbine.

[0017] In some embodiments, the wind farm device includes casters connected to the main structure to enable the wind farm device to be moved; and / or, The wind farm equipment includes a power supply electrically connected to the wind farm units to provide electrical energy to the wind farm units; and / or, The material of the main structure includes aluminum material.

[0018] An embodiment of the second aspect of the present invention provides a complex wind field generation method, which is used for any of the above-mentioned wind field equipment. The complex wind field generation method includes: inputting a first control signal into the first controller; The first controller adjusts the air outlet state of the wind farm unit; The deflector is driven to rotate in the horizontal direction to adjust the air outlet angle.

[0019] In some embodiments, the step of inputting the first control signal to the first controller includes: The fan is driven to complete a jump from 0 to rated speed within 50ms, and the deflector instantly changes the airflow direction to form a transient gust; and / or, Driving multiple wind farm units to periodically adjust their rotational speeds according to a sinusoidal curve, with adjacent units having a phase difference of 180° to simulate periodic gust fluctuations; and / or, Control the wind speed difference between the upper and lower wind farm units in the vertical direction, and at the same time form a horizontal and vertical composite wind shear by setting the guide plate at an angle of 25°-35° to the horizontal plane; and / or, The wind field unit is driven to randomly adjust the rotation speed within the range of ±20%, and the wind direction deflection within the range of ±15°, and cooperate with the rectifier component to generate a three-dimensional turbulent flow field.

[0020] According to the above embodiments, the beneficial effects of the present invention are: The wind farm equipment of the present invention includes a main structure, a supporting structure, a wind farm unit, a first controller, and a guide plate. The main structure serves as the foundation for the entire wind farm equipment and is used to mount other components. The supporting structure is connected to the main structure and is spaced apart vertically. For example, the supporting structure is a support plate, with multiple support plates extending horizontally and spaced apart vertically. The wind farm unit is connected to one side of the supporting structure in the vertical direction. Multiple wind farm units can be placed on a support plate (supporting structure). The wind farm unit includes a fan and a rectifier assembly. The fan is suitable for generating airflow. The rectifier assembly is located on one side of the fan outlet and can optimize the airflow generated by the fan. For example, the fan includes blades and a motor that drives the blades to rotate. The airflow generated by the fan is a combination of linear motion and rotational motion. When such an airflow passes through the rectifier assembly, it is affected by the rectifier assembly and converts part of the rotational velocity component into a forward velocity component, thereby allowing the airflow to be projected to a farther location and making the airflow more uniform and stable. The first controller is connected to the wind farm unit and is used to adjust the wind speed of the wind farm unit, enabling it to achieve a variety of air output conditions. A deflector is connected to the main structure and corresponds to the position of the wind farm unit. Along the direction of the wind turbine's airflow, the support structure has a first side and a second side, with the deflector located on at least a portion of the second side of the support structure. This design allows the deflector to guide the airflow out of the rectifier assembly.

[0021] Specifically, the deflectors are configured to rotate around the horizontal axis. For example, when the deflectors are rotated to form a 30° angle with the supporting structure, the airflow exiting the rectifier assembly corresponding to the deflector can also flow obliquely to the horizontal direction due to the influence of the deflectors. This means that the present application can adjust the vertical wind direction. Furthermore, the deflectors can be configured to form different inclination angles with the horizontal direction, and in conjunction with the wind field unit, various complex wind field simulations can be achieved.

[0022] In addition, the deflector can also continuously change its inclination angle in the horizontal direction, so that the wind direction can continuously change in the vertical direction.

[0023] In summary, the present application can realize dynamic and non-uniform wind field simulation, complete vertical wind direction control, independent control of the wind field and simulation of complex wind fields.

[0032] Reference below Figures 1 to 9 To describe the wind farm equipment and complex wind farm generation method according to an embodiment of the present invention. Figure 1 and Figure 2The wind farm equipment of the present invention includes a main structure 100, a supporting structure 200, a wind farm unit 300, a first controller and a guide plate 400. The main structure 100 serves as the basic structure of the entire wind farm equipment and is used to install other components. The supporting structure 200 is connected to the main structure 100, and the supporting structures 200 are spaced apart in the vertical direction to provide a multi-level installation platform. For example, the supporting structure 200 is a support plate, and multiple support plates extend in the horizontal direction and are spaced apart in the vertical direction. The wind farm unit 300 is connected to one side of the supporting structure 200 in the vertical direction. Multiple wind farm units 300 can be placed on one support plate (supporting structure 200). The wind farm unit 300 includes a fan and a rectifier assembly 310. The fan is suitable for generating airflow. The rectifier assembly 310 is arranged on one side of the air outlet of the fan. The rectifier assembly 310 can optimize the airflow generated by the fan, such as optimizing the stability of the airflow. Specifically, for example, the fan includes blades and a motor that drives the blades to rotate. The airflow generated by the fan is a combination of linear motion and rotational motion. When such an airflow passes through the rectifier assembly 310, it will be affected by the rectifier assembly 310 to convert the rotational velocity component into a forward velocity component, so that the airflow can be directed to a farther position and the airflow is more uniform and stable. The first controller is connected to the wind field unit 300. The first controller is used to adjust the wind speed of the wind field unit 300 so that the wind field unit 300 has a variety of air outlet states. The guide plate 400 is connected to the main structure 100, and the guide plate 400 corresponds to the position of the wind field unit 300. Along the airflow direction of the fan, the supporting structure 200 has a first side and a second side distributed in sequence, and the guide plate 400 is located on the second side of at least part of the supporting structure 200. With this design, the guide plate 400 can guide the airflow flowing out of the rectifier assembly 310.

[0033] Specifically, the deflector 400 is configured to rotate circumferentially around the horizontal direction. For example, when the deflector 400 rotates to form a 30° angle with the supporting structure 200, the airflow flowing out of the rectifying assembly 310 corresponding to the deflector 400 can also flow obliquely relative to the horizontal direction due to the influence of the deflector 400. In other words, the present application can adjust the vertical wind direction. Furthermore, each deflector 400 can be configured to form different inclination angles with the horizontal direction, cooperating with the wind field unit 300 to simulate various complex wind fields.

[0034] In addition, the guide plate 400 can also continuously change its inclination angle with respect to the horizontal direction, so that the wind direction can continuously change in the vertical direction.

[0035] In summary, the present application can realize dynamic and non-uniform wind field simulation, complete vertical wind direction control, independent control of the wind field and simulation of complex wind fields.

[0036] Regarding the main structure 100, in some embodiments, the main structure 100 is constructed of high-strength, lightweight aluminum profiles (e.g., 6061-T6 aluminum alloy), assembled into a removable frame using standard components such as angle brackets and bolts. Lockable universal wheels are integrated at the bottom to accommodate mobility, and a lifting interface is provided at the top, balancing the requirements of rapid movement and fixed installation. A modular partitioning design is employed, with aluminum profile partitions 500 dividing the interior into an air intake zone, a wind farm generation zone, and a control zone to optimize airflow paths and reduce interference between modules. Parts of the main structure 100 can be designed as hollow columns to reduce the mass of the wind farm equipment and facilitate its movement.

[0037] Regarding the vertical spacing of the supporting structures 200, it should be understood that "vertically spacing" here refers to a macroscopic distribution of the supporting structures 200 exhibiting varying heights. A vertical height difference between the supporting structures 200 is sufficient. The specific arrangement of the supporting structures 200, such as whether they are arranged in a strictly vertical, upward sequence, or at an angle along the vertical direction, is also within the scope of protection of this application.

[0038] Regarding the connection between the wind farm unit 300 and the supporting structure 200 , in some embodiments, the wind farm unit 300 is detachably connected to the supporting structure 200 to form a modular assembly, which facilitates replacement of different wind farm units 300 in the wind farm equipment.

[0039] Furthermore, in some embodiments, the rectifier assembly 310 of the wind farm unit 300 is fixedly connected to the supporting structure 200, and the wind turbine and the supporting structure 200 are detachably connected to improve assembly efficiency. In other words, the rectifier assembly 310 and the supporting structure 200 can be considered as a whole. After this whole is assembled on the main structure 100, the wind turbine is then installed in the position corresponding to the rectifier assembly 310.

[0040] Regarding the first controller, it is understood that in some embodiments, the first controller can independently adjust the wind speed of each wind farm unit 300 to make the wind farm equipment more flexible. In some embodiments, the first controller can uniformly adjust the wind speed of all wind farm units 300.

[0041] The deflector 400 is movably connected to the main structure 100, where the movably connected means that the deflector 400 can rotate relative to the main structure 100, and / or the deflector 400 and the main structure 100 are detachably connected. In some embodiments, the deflector 400 can also slide relative to the main structure 100 to adjust the wind farm units 300 at different heights, or by changing the distance between the deflector 400 and the rectifier assembly 310, the deflector 400 at the same inclination angle can produce different diversion effects on the same wind farm unit 300. Among them, although the key to adjusting the wind direction in the vertical direction of the present application is that the deflector 400 can rotate around the horizontal direction relative to the supporting structure 200, other installation methods of the deflector 400 can affect the flow direction of the airflow of the wind farm equipment, so the above design methods of the deflector 400 are all within the scope of protection of the present application.

[0042] Regarding the description of the guide plate 400 corresponding to the wind farm unit 300, specifically, the guide plate 400 is used to guide the direction of the airflow emitted from the wind farm unit 300, so the location of the guide plate 400 only needs to be sufficient to guide the direction of the airflow. For example, the supporting structure 200 is plate-shaped, and multiple wind farm units 300 are spaced apart along its length. The guide plate 400 can match the length of these multiple wind farm units 300 and have a guiding effect on the airflow emitted from these wind farm units 300. The guide plate 400 can also only extend to the position of some wind farm units 300 and only have a guiding effect on the airflow emitted from some wind farm units 300. The specific design depends on the actual situation and only needs to ensure that the guide plate 400 can rotate circumferentially in the horizontal direction. Furthermore, the guide plate 400 can be a single plate, or it can be multiple plates spaced apart along the horizontal direction. The guide plate 400 may correspond to only one of the supporting structures 200 and the wind farm unit 300 installed on the supporting structure 200 , or the guide plate 400 may correspond one-to-one to multiple supporting structures 200 and the wind farm units 300 installed on each supporting structure 200 .

[0043] Furthermore, regarding the description of the guide plate 400 being configured to be able to rotate circumferentially around the horizontal direction, specifically, the rotation axis can be located at the edge of the guide plate 400 facing the supporting structure 200, or the rotation axis can be located at the center of the guide plate 400, and the airflow direction in the vertical direction can be changed simply by rotating the guide plate 400. In addition, it is understandable that the guide plate 400 can be set at a position at the same height as the supporting structure 200, or the guide plate 400 can be set at a position slightly lower than the supporting structure 200, and the airflow direction in the vertical direction can be changed simply by rotating the guide plate 400. Based on the above explanation, the core of this application lies in the design of the guide plate 400 rotating around the horizontal direction. There is no restriction on the installation position and the position of the rotation axis of the guide plate 400. The design of the guide plate 400 that can change the airflow direction in the vertical direction is within the scope of protection of this application.

[0044] It is understandable that in some embodiments, in order to adapt to different experimental needs, the main structure 100 can adopt a modular design, allowing the user to increase or decrease the number of supporting structures 200 as needed. In this way, the wind farm equipment can not only expand its height, but also increase or decrease the number of wind farm units 300 to meet the testing needs of different scales. In addition, the deflector 400 can be replaced with a design with a variable curvature surface to more finely control the direction of the airflow. For example, the deflector 400 made of a flexible material can automatically adjust its shape according to changes in the airflow, thereby more accurately controlling the direction of the airflow.

[0045] It will be appreciated that in some embodiments, the baffles 312 of the rectifying assembly 310 can be designed as a movable structure, that is, each baffle 312 can independently rotate a certain angle. This design allows the rectifying assembly 310 to not only adjust the overall direction of the airflow, but also fine-tune the speed and direction of local airflow, increasing the diversity of wind farm simulation. For example, by programmatically controlling the rotation angle of each baffle 312, a variety of airflow patterns, such as spiral airflow or bifurcated airflow, can be simulated within a single wind farm unit 300, greatly enriching the application scenarios of wind farm equipment.

[0046] Reference Figures 1 to 3The edge of the deflector 400 close to the wind farm unit 300 is the first edge 410. The wind farm equipment includes a second controller, which is connected to the deflector 400 to drive the deflector 400 to rotate around the first edge 410. The rotation angle θ of the deflector 400 relative to the supporting structure 200 satisfies: 0°≤θ≤45°, for example, θ is 0°, 10°, 20°, 30°, 45°, preferably 30°. The angle of the deflector 400 can be constant at a certain value or can be continuously and dynamically adjusted. This mechanism enables the deflector 400 to change the direction of the airflow more flexibly, thereby better simulating various complex wind farm conditions. Since the angle of the deflector 400 can be precisely controlled, subtle adjustments to the airflow direction can be achieved, which is particularly important for simulating specific meteorological phenomena such as gusts, gusts, wind shear and turbulence. For example, when simulating gusts, the second controller can quickly adjust the angle of the deflector 400 according to a preset program, cooperating with the first controller to adjust the wind speed, to achieve the periodic fluctuation effect of the gusts. This linkage mechanism not only improves simulation accuracy but also enhances its realism. Furthermore, the baffles 312 in the rectifying assembly 310 continue to function, ensuring that even with frequent changes in airflow direction, the airflow maintains a certain degree of stability and uniformity. This helps enhance the wind field simulation, making it more realistic.

[0047] It will be appreciated that in some embodiments, the second controller may incorporate an intelligent algorithm to automatically adjust the angle of the deflector 400 based on real-time monitored airflow parameters. For example, sensors installed within the wind farm unit 300 can detect the speed and direction of the airflow in real time and feed this data back to the second controller. Based on this information, the second controller utilizes a built-in optimization algorithm to calculate the optimal angle of the deflector 400, thereby achieving optimal control of the airflow. This intelligent design not only enhances the operational convenience of the wind farm equipment but also significantly improves the accuracy and efficiency of the simulation.

[0048] In some embodiments, the first controller is configured to adjust the wind speed of the wind farm unit 300 so that the wind farm equipment can complete at least one of gust simulation, gust simulation, wind shear simulation, and turbulence simulation.

[0049] Specifically, in some embodiments, the first controller is configured to adjust the wind speed of the wind farm unit 300 to enable the wind farm equipment to simulate a gust. For example, when simulating a gust, the first controller can drive the wind turbine to complete a jump from 0 to rated speed within 50ms, coordinating with the deflector 400 to instantly change the airflow direction, creating a transient gust. During this process, the deflector 400 can quickly adjust to a specific angle, causing the airflow to rapidly change direction and reach high wind speeds in a short period of time, thereby simulating the characteristics of a gust, namely, the effect of a dramatic change in wind speed and direction within a very short period of time.

[0050] In some embodiments, the first controller is configured to adjust the wind speed of the wind farm unit 300 so that the wind farm equipment can perform gust simulation. For example, when gust simulation is required, the first controller periodically adjusts the rotation speed of the wind farm unit 300 according to a preset sinusoidal curve, with adjacent units having a phase difference of 180°. Specifically, under the control of the first controller, the rotation speeds of the multiple wind farm units 300 will change periodically according to the law of the sinusoidal curve, and adjacent wind farm units 300 will have a phase difference of 180°, thus forming periodic wind speed fluctuations in space, thereby achieving gust simulation, that is, simulating the gust phenomenon in which the wind speed changes periodically over time.

[0051] In some embodiments, the first controller is configured to be able to adjust the wind speed of the wind farm unit 300 so that the wind farm equipment completes wind shear simulation. For example, when wind shear needs to be simulated, the first controller controls the wind speed difference between the upper and lower layers of wind farm units 300 in the vertical direction, and at the same time, by setting the guide plate 400 to be at an inclination angle of 25°-35° with the horizontal plane, a composite wind shear in the horizontal and vertical directions is formed. Specifically, the first controller accurately controls the wind speed of the upper and lower layers of wind farm units 300 to be different, thereby generating a wind speed gradient in the vertical direction, and then combined with the angle adjustment of the guide plate 400, so that the airflow has wind speed changes in both the horizontal and vertical directions, thereby simulating the wind shear phenomenon, that is, the situation where there is a significant difference in wind speed at different heights or positions in space.

[0052] In some embodiments, the first controller is configured to be able to adjust the wind speed of the wind field unit 300 so that the wind field equipment can complete turbulence simulation. For example, when turbulence simulation is required, the first controller drives the wind field unit 300 to randomly adjust the rotation speed within the range of ±20%, and adjust the wind direction deflection within the range of ±15°, and cooperate with the rectifier component 310 to generate a three-dimensional turbulent field. Specifically, under the action of the first controller, the rotation speed of the wind field unit 300 will randomly change within the range of ±20% of the rated speed, and the guide plate 400 will also randomly adjust the angle within the range of ±15°, so that the direction and speed of the airflow are constantly changing, and the rectifier component 310 will further adjust the airflow, and finally generate an irregular three-dimensional turbulent field, simulating the complex airflow state of turbulence, that is, the wind speed and wind direction show irregular changes in space and time. Turbulence phenomenon.

[0053] It will be appreciated that in some embodiments, the first controller can automatically adjust the wind speed of wind farm unit 300 based on sensor data. For example, wind speed sensors can be installed within wind farm unit 300 to monitor the speed and direction of airflow in real time and feed this data back to the first controller. Based on this information, the first controller can dynamically adjust the wind speed of wind farm unit 300 to ensure a more realistic and accurate simulation. Furthermore, artificial intelligence algorithms can be introduced to further optimize the simulation process and improve its efficiency and accuracy.

[0054] Reference Figure 2 In some embodiments, the rectifying assembly 310 includes an outer shell 311 and a baffle 312. Along the direction of airflow, the outer shell 311 has a hollow area running through it, and the baffle 312 is arranged in the hollow area. The baffle 312 has a plate surface distributed circumferentially around the direction of airflow, and the plate surfaces are all parallel to the direction of airflow. This design helps to guide and stabilize the airflow, reduce turbulence and improve the uniformity of the airflow. When the airflow passes through the baffle 312, due to the presence of the baffle 312, the airflow is forced to flow along a predetermined path, reducing the disordered movement of the airflow, thereby achieving the rectifying effect of the airflow. Specifically, the airflow generated by the fan has a forward velocity component and a rotational velocity component. The baffle 312 can effectively convert the rotational velocity component into a forward velocity component, which not only makes the air outlet more stable, but also increases the wind speed and range. In some embodiments, the outer shell 311 is a circular frame, and the baffle 312 is a plate extending radially thereof. There may be only one baffle 312 or multiple baffles 312 . For example, three baffles 312 extending radially are arranged crosswise, and the intersection position is located at the center of the outer shell 311 .

[0055] It is understood that in some embodiments, the baffle 312 can be designed with an adjustable structure, that is, the angle of each baffle 312 can be adjusted independently. For example, by providing a rotating shaft and a locking mechanism between the baffle 312 and the outer shell 311, each baffle 312 can be rotated to a certain angle as needed. This design allows the rectifier assembly 310 to not only adjust the overall direction of the airflow, but also fine-tune the speed and direction of the local airflow, thereby increasing the diversity of wind field simulation. For example, by programming the angles of each baffle 312, a variety of airflow patterns, such as spiral airflow or bifurcated airflow, can be simulated within a single wind field unit 300.

[0056] It will be appreciated that, in some embodiments, the outer shell 311 can be modularly designed, allowing the user to replace different combinations of baffles 312 as needed. For example, baffles 312 of different shapes and sizes can be provided, and the user can select the appropriate baffle 312 for installation based on specific experimental requirements. In addition, the outer shell 311 itself can also be designed to be detachable for easy cleaning and maintenance. This modular design not only improves the flexibility of the equipment, but also extends the service life of the equipment and reduces maintenance costs. For example, when it is necessary to simulate special airflow characteristics, the user can select a baffle 312 of a specific shape to obtain the best rectification effect.

[0057] Reference Figure 2 In some embodiments, the cross-section of the outer shell 311 cut by a vertical plane is circular, and the rectifying assembly 310 includes multiple baffles 312, and the cross-sections of the multiple baffles 312 cut by the vertical plane all intersect at the center of the circle. When conducting wind field simulation experiments, this design can ensure that the airflow remains consistent throughout the entire test area, avoiding the impact of local turbulence on the experimental results. In addition, the rotation function of the guide plate 400 combined with the rectifying assembly 310 can achieve precise control of the airflow direction and speed, thereby simulating complex airflow conditions.

[0058] It will be appreciated that in some embodiments, the cross-sectional shape of the outer shell 311 may also be square, for example, and the number and shape of the baffles 312 may be adjusted based on specific experimental requirements. For example, to simulate a specific airflow pattern, a different number of baffles 312 may be selected and their angles adjusted as needed. Assuming three baffles 312 are used, the angle of each baffle 312 can be independently adjusted, thereby generating different airflow distribution patterns, such as spiral airflow or bifurcated airflow. In this way, a variety of complex airflow conditions can be simulated more flexibly.

[0059] Reference Figure 3 In some embodiments, the wind farm units 300 are evenly spaced along the horizontal direction. In some embodiments, the wind farm units 300 are evenly spaced along the vertical direction. Based on this, the wind farm units 300 can be designed in a 6 by 6 array, etc. This layout design helps to ensure that the airflow is evenly distributed throughout the test area and reduce the occurrence of local turbulence. Specifically, the supporting structure 200 is spaced apart in the vertical direction for installing multiple wind farm units 300. Each wind farm unit 300 includes a fan and a rectifier assembly 310. The fan generates airflow, and the rectifier assembly 310 is provided on one side of the fan outlet to adjust the direction and stability of the airflow.

[0060] After airflow is generated by the fan, it is guided by the rectifying assembly 310 and flows along a predetermined path toward the guide plate 400. Because the wind farm units 300 are evenly distributed horizontally and vertically, the airflow is evenly distributed throughout the entire test area, thereby enhancing the realism of the simulation. For example, when conducting large-scale wind farm simulations, this layout design ensures consistent airflow at different heights and locations, avoiding experimental errors caused by uneven airflow.

[0061] It will be appreciated that in some embodiments, the distribution density of wind farm units 300 can be adjusted based on actual needs. For example, to simulate a high-intensity wind farm environment, the number of wind farm units 300 can be increased and the spacing between them can be reduced. This can improve the strength and stability of the airflow, making it suitable for studying the impact of strong winds on buildings or other facilities. Conversely, if a low-intensity wind farm environment is desired, the number of wind farm units 300 can be reduced and the spacing between them increased.

[0062] It is understood that in some embodiments, the position of the wind farm unit 300 can be dynamically adjusted according to experimental requirements. For example, by providing a slide rail and a locking mechanism on the supporting structure 200, the wind farm unit 300 can be freely moved in the horizontal and vertical directions and fixed in a specific position as needed. This design not only enables fine control of airflow distribution, but also makes it convenient for researchers to quickly adjust the experimental settings and improve experimental efficiency. For example, when studying wind field characteristics at different heights, the required data can be obtained by adjusting the position of the wind farm unit 300.

[0063] Reference Figures 1 to 5 In some embodiments, between two adjacent supporting structures 200, the wind field units 300 are stacked in at least two layers in the vertical direction. When the fan generates airflow, the airflow is initially rectified by the rectifying assembly 310 and then directed to the guide plate 400. Due to the multi-layer stacking of the wind field units 300, the intensity of the airflow is different at different height layers, and the airflow intensity at different heights can be adjusted by adjusting the outlet speed of the wind field units 300 at each layer. For example, when conducting a high-rise building wind field simulation experiment, the wind speed difference between the ground layer and the high-altitude layer can be simulated by controlling the different rotation speeds of the upper and lower layers of the wind field units 300, thereby better simulating the wind field characteristics under actual meteorological conditions, and the vertical direction airflow simulation can be better achieved by guiding the guide plate 400 in the vertical direction.

[0064] It is understood that in some embodiments, the number of wind farm units 300 layers can be adjusted based on specific experimental requirements. For example, to simulate extreme weather conditions, such as a strong typhoon or tornado, more layers of wind farm units 300 can be added to effectively simulate airflow at higher levels. Assuming that in certain experimental scenarios, it is necessary to simulate a wind farm environment with more than 10 layers, this can be achieved by increasing the number of supporting structures 200 and stacking more layers of wind farm units 300 accordingly.

[0065] It will be appreciated that in some embodiments, the vertical spacing of wind farm units 300 can also be adjusted based on experimental requirements. For example, when studying low-level jet stream phenomena, the spacing between upper and lower layers of wind farm units 300 can be reduced to simulate a denser airflow layer. For example, by providing adjustable brackets on the supporting structure 200, the spacing between each layer of wind farm units 300 can be flexibly adjusted according to actual needs to meet different experimental requirements.

[0066] Reference Figures 5 to 8 In some embodiments, the main structure 100 includes horizontally opposed supporting side beams 110, and the load-bearing structure 200 is plate-shaped and detachably connected between the two opposing supporting side beams 110. This design not only improves the overall stability and reliability of the equipment but also facilitates maintenance and component replacement.

[0067] It is understood that in some embodiments, the design of the supporting side beams 110 can be further optimized to improve the stability of the overall structure. For example, the supporting side beams 110 can adopt a double-layer or multi-layer structure, with reinforcing materials such as carbon fiber or high-strength alloys filling the middle to enhance its bending stiffness and durability. Specifically, double-layer supporting side beams 110 can significantly improve the stability of the device under high wind speed conditions, ensuring the accuracy of experimental results.

[0068] It will be appreciated that in some embodiments, the connection method of the support structure 200 can be diversified. For example, in addition to traditional bolt connections, latch-type or snap-on connections can also be used, making the assembly and disassembly process simpler and faster. For example, the latch-type connection allows the user to complete the installation and disassembly of the support structure 200 with a simple insertion and removal operation, greatly improving work efficiency. At the same time, this design is also suitable for situations where experimental configurations are frequently changed, providing greater convenience for researchers.

[0069] Reference Figures 1 to 8In some embodiments, the main structure 100 includes a top support beam 120 and a bottom support beam 130 that are relatively distributed in the vertical direction. The top support beam 120, the side support beams 110, and the bottom support beam 130 collectively enclose an airflow channel 140, and the wind farm unit 300 is disposed within the airflow channel 140. In the direction of airflow, the top support beam 120, the side support beams 110, and the bottom support beam 130 all protrude from the wind farm unit 300, and / or in the opposite direction of airflow, the top support beam 120, the side support beams 110, and the bottom support beam 130 all protrude from the wind farm unit 300. With this design, the extended portions (protruding portions) of the top support beam 120, the side support beams 110, and the bottom support beam 130 constitute the airflow channel 140, such as the air intake rectifier module shown in Figure x, which can improve air intake efficiency.

[0070] It will be appreciated that in some embodiments, the top support beam 120 and the bottom support beam 130 can be designed as a modular structure to facilitate rapid assembly and disassembly according to different experimental requirements. For example, the top support beam 120 and the bottom support beam 130 with a standardized interface design can increase or decrease the number of layers as needed, and flexibly adjust the height of the airflow channel 140 to accommodate experiments of different scales.

[0071] It is understood that in some embodiments, the connections between the top support beam 120, the side support beams 110, and the bottom support beam 130 can adopt a plug-in or magnetic design to facilitate quick installation and removal. For example, magnetic connectors can quickly install and remove the support beams without the use of tools, greatly improving the efficiency of equipment maintenance and commissioning. In addition, this design can also improve the portability and flexibility of the equipment, facilitating its transfer between different locations.

[0072] Reference Figure 5 In some embodiments, the wind farm equipment further includes partitions 500 connected to the main structure 100 and arranged horizontally at intervals. The partitions 500 intersect with the supporting structure 200 to form a storage compartment for accommodating the wind turbines. This design not only improves the utilization of the internal space of the equipment but also makes the layout of the various components more compact and reasonable.

[0073] During actual operation, when the fan generates airflow, it is first preliminarily processed by the rectifying assembly 310 to ensure that the airflow is smooth and uniform. Subsequently, the processed airflow enters the airflow channel 140 enclosed by the supporting side beams 110, the supporting top beam 120 and the supporting bottom beam 130. Due to the presence of the partition 500, the main structure 100 is divided into a plurality of independent spaces or storage compartments, each of which can accommodate a fan separately. In this way, it is not only convenient for the operation and maintenance of a single fan, but also can effectively reduce the mutual interference between different fans. In addition, the guide plate 400 is located on the second side of the supporting structure 200 and can rotate circumferentially around the horizontal direction, which further enhances the ability to control the direction of the airflow, thereby realizing the simulation of a complex wind field environment.

[0074] It is understood that in some embodiments, the partition 500 can be made of a multi-layer composite material, such as glass fiber reinforced plastic (GFRP). This not only provides good mechanical strength but also effectively reduces noise. For example, a three-layered partition 500, with a middle layer of sound-absorbing material and two sides of GFRP sheet material, can significantly reduce noise levels during operation and improve the comfort of the experimental environment.

[0075] It is understood that in some embodiments, the partition 500 may also be provided with ventilation holes or guide grooves to facilitate adjustment of airflow distribution. For example, a series of guide grooves may be provided on the side of the partition 500 near the fan. These guide grooves can be adjusted in angle as needed to ensure that the airflow flows along a predetermined path, thereby optimizing the performance of the entire system.

[0076] In some embodiments, the wind farm equipment includes casters, which are connected to the main structure 100 so that the wind farm equipment can be moved. In some embodiments, the wind farm equipment includes a power supply 700, which is electrically connected to the wind farm unit 300 to provide electrical energy to the wind farm unit 300. In some embodiments, the material of the main structure 100 includes aluminum material. The design of the casters allows the equipment to be easily transferred between different experimental sites. For example, when conducting outdoor wind farm simulation experiments, the equipment can be quickly moved to a designated location via casters, greatly improving the efficiency of the experiment. The provision of the power supply 700 makes the equipment no longer dependent on an external power supply 700, and is particularly suitable for use in the wild or in places where there is no fixed power supply 700. The main structure 100 is made of aluminum profiles, which not only reduces the overall weight of the equipment, but also enhances its corrosion resistance and durability, making it suitable for long-term use.

[0077] It is understood that in some embodiments, the casters can be designed with a locking function to ensure that the device remains stable and immobile in a specific position. For example, the casters can be equipped with an automatic locking device. Once the device is moved to a predetermined position, simply pressing the lock button can prevent the device from accidentally moving due to external factors, thereby ensuring stability during the experiment.

[0078] It is understandable that in some embodiments, the power supply 700 can be of a detachable design, which is convenient for replacement or charging according to experimental needs. For example, by adopting a modular power supply 700 group design, users can flexibly choose power supply 700 groups of different capacities according to actual needs to meet the needs of different experimental times. At the same time, the power supply 700 group has a fast charging function, which can complete charging in a short time, further improving the convenience of use of the equipment. In addition, the aluminum profiles in the main structure 100 can increase wear resistance and corrosion resistance through surface treatment technology, thereby extending the service life of the equipment. For example, the anodizing treatment process can form a hard protective film on the surface of the aluminum profile, significantly improving its weather resistance.

[0079] Regarding the electrical system of this application, the power supply module 700 further adopts an AC / DC dual-power supply solution: when connected to the mains, it outputs a 48V DC power supply 700 through an AC / DC converter; when operating in the field, it switches to the built-in lithium power supply 700 group (supporting ≥4 hours of continuous operation); independent power supply circuit: each wind farm unit 300, control panel, and sensor are equipped with independent circuit breakers to prevent local failures from causing global power outages. The signal controller 900 is based on an industrial-grade PLC (programmable logic controller) or distributed control system (DCS), equipped with an Ethernet interface and a touch screen human-machine interface. Its control logic includes the following: ① Preset mode: built-in standard wind farm models such as gusts, turbulence, etc., which can be called up with one click; ② Custom mode: users can set the wind speed, wind direction, and start and stop sequence of each unit through the interface to generate a personalized wind farm; ③ Real-time feedback: integrated wind speed sensors (such as hot wire anemometers) collect wind farm data in real time and adjust control parameters in a closed loop.

[0080] In addition, the present application also includes a safety switch 800 and a protection system. The present application includes an independent safety switch 800, and a red emergency stop button is set in the equipment control area and near each module. When pressed, the corresponding wind farm unit 300 power supply 700 is immediately cut off, and the vertical wind direction control panel position is locked at the same time. The present application includes overload protection: the power supply 700 module has a built-in current sensor, and when the current of a single wind farm unit 300 exceeds 1.2 times the rated value, it automatically reduces speed or shuts down. The present application includes an anti-pinch design: an infrared grating is set in the movement area of ​​the vertical wind direction control panel, and the action is paused and an alarm is issued when a human body is detected approaching.

[0081] Reference Figures 1 to 9 The second embodiment of the present invention provides a complex wind field generation method for the wind field equipment of any of the above embodiments, referring to Figure 9 , complex wind field generation methods include: S101: inputting a first control signal to a first controller; S103: The first controller adjusts the air outlet state of the wind farm unit 300; S105: driving the guide plate 400 to rotate in a horizontal direction to adjust the air outlet angle.

[0082] After receiving the instruction, the first controller will adjust the working state of the wind farm unit 300 according to the set parameters. For example, the speed and pressure of the airflow can be adjusted by changing the speed of the fan. At the same time, since the guide plate 400 can rotate circumferentially around the horizontal direction, its position can be precisely adjusted according to actual needs. This design enables the device to not only generate airflows of different speeds, but also to achieve continuous and dynamic airflow direction adjustment in the vertical direction, thereby simulating various complex wind farm conditions. In addition, the design of the support structure 200 spaced apart in the vertical direction ensures that the multi-layer wind farm units 300 will not interfere with each other, ensuring the stability and reliability of the entire system.

[0083] It will be appreciated that in some embodiments, to more precisely control the direction of airflow, sensors can be installed on the edges of the deflector 400. These sensors can monitor the speed and direction of the airflow in real time and feed this data back to the first controller. For example, a piezoelectric anemometer can be used as a sensor, as it can quickly respond to changes in airflow and provide highly accurate data. Based on this data, the first controller can further optimize the output state of the wind farm unit 300, thereby improving the realism and accuracy of the simulation.

[0084] In some embodiments, the step of inputting the first control signal to the first controller includes: The fan is driven to complete a jump from 0 to rated speed within 50ms, and the deflector 400 is used to instantly change the airflow direction to form a transient gust; and / or, Driving multiple wind farm units 300 to periodically adjust their rotational speeds according to a sinusoidal curve, with adjacent units having a phase difference of 180° to simulate periodic gust fluctuations; and / or, Controlling the wind speed difference between the upper and lower wind farm units 300 in the vertical direction, and simultaneously forming a horizontal and vertical composite wind shear by setting the guide plate 400 at an inclination angle of 25°-35° with the horizontal plane; and / or, The wind field unit 300 is driven to randomly adjust the rotation speed within the range of ±20% and the wind direction deflection within the range of ±15°, and cooperates with the rectifier component 310 to generate a three-dimensional turbulent flow field.

[0085] Reference Figures 1 to 9Specifically, when simulating a transient gust, the first controller, upon receiving the corresponding control signal, rapidly drives the fan to accelerate from 0 to rated speed within 50 milliseconds. At this point, the fan speed instantly reaches its maximum value, generating a powerful airflow. Simultaneously, the deflector 400 instantly adjusts to a specific angle according to a preset program. This angle typically allows the airflow to quickly change direction and be directed toward a designated area. This rapid increase in wind speed and change in wind direction collectively create the effect of a transient gust. In this way, gusts with rapid changes in wind speed and direction can be simulated in a short period of time, providing a realistic gust environment for related experiments or tests. When simulating periodic gust fluctuations, the first controller periodically adjusts the speed of the wind farm unit 300 according to a preset sinusoidal curve. Specifically, under the control of the first controller, the speeds of the multiple wind farm units 300 vary periodically according to a sinusoidal curve. Furthermore, a 180° phase difference is set between adjacent wind farm units 300. This means that when the rotation speed of one wind farm unit 300 is at its peak, the rotation speed of the adjacent wind farm unit 300 may be at its valley, and vice versa. By setting this phase difference, wind farm units 300 at different locations generate airflows of different intensities at different times, thereby forming periodic wind speed fluctuations in space. This periodic wind speed change can well simulate the common gust phenomenon in nature, providing a reliable simulation basis for related research. In order to form a composite wind shear in the horizontal and vertical directions, the first controller controls the wind speed difference between the upper and lower layers of wind farm units 300 in the vertical direction. Specifically, by precisely controlling the different wind speeds of the upper and lower layers of wind farm units 300, a wind speed gradient is generated in the vertical direction. For example, the wind speed of the upper wind farm unit 300 may be set to a higher value, while the wind speed of the lower wind farm unit 300 is relatively low, thereby forming a significant wind speed difference in the vertical direction. At the same time, the deflector 400 will be set to an inclination angle of 25°-35° with the horizontal plane. Through this angle setting, the deflector 400 can further adjust the direction of the airflow flowing out of the wind farm unit 300, so that the airflow also has a certain wind speed change in the horizontal direction. In this way, combined with the wind speed gradient in the vertical direction and the wind speed change in the horizontal direction, a composite wind shear phenomenon in the horizontal and vertical directions is ultimately formed. This composite wind shear can more realistically simulate the complex wind shear conditions in the actual atmospheric environment, providing a valuable simulation scenario for related research and testing. When generating a three-dimensional turbulent flow field, the first controller will drive the wind farm unit 300 to randomly adjust the speed within the range of ±20% of the rated speed. This random speed change makes the airflow speed generated by each wind farm unit 300 different and there is no fixed pattern. At the same time, the deflector 400 will also randomly adjust the angle within the range of ±15°. Due to the random changes in the angle of the deflector 400, the direction of the airflow will also change irregularly.Furthermore, the rectifying assembly 310 continues to function throughout the entire process, rectifying and adjusting the airflow to a certain degree. Although the rectifying assembly 310 maintains a certain degree of stability and uniformity in the airflow, the random rotational speed variations of the wind field unit 300 and the random angle adjustments of the guide plates 400 result in an irregular three-dimensional turbulent flow field in both space and time. This three-dimensional turbulent flow field can simulate the complex turbulent phenomena found in nature, providing an effective experimental method for studying the effects of turbulence on various objects or systems.

[0086] In summary, the main working principles and processes of this application are as follows: (1) Complex wind field generation logic Gust simulation: The signal controller 900 sends a step signal to the target wind farm unit 300, driving the wind turbine to complete a jump from 0 to rated speed within 50ms. The deflector 400 instantly changes the airflow direction, forming a transient gust. Gust simulation: Set multiple wind farm units 300 to periodically adjust their rotation speed according to a sinusoidal curve (e.g., period 5s, amplitude ±30% of rated wind speed), with adjacent units having a phase difference of 180° to simulate periodic gust fluctuations; Wind shear simulation: Control the wind speed difference between the upper and lower wind farm units 300 in the vertical direction (e.g., 10 m / s in the upper layer and 5 m / s in the lower layer), and simultaneously set a 30° inclination angle on the guide vanes 400 to generate composite wind shear in the horizontal and vertical directions. Turbulence simulation: Each wind field unit 300 randomly adjusts the rotation speed (fluctuation range ±20%) and wind direction (±15° deflection), and cooperates with the baffle 312 (detachable) at the outlet of the rectifier assembly 310 to generate a three-dimensional turbulent flow field.

[0087] (2) Vertical wind direction control process The user inputs the vertical wind direction angle (e.g., θ=30°) through the signal controller 900; The controller calculates the target rotation angle of the multi-layer guide plate 400; The servo motor drives the guide plate 400 to rotate synchronously, and the angle encoder provides real-time feedback of the position signal; The wind speed sensor detects the vertical wind speed component and adjusts the fan speed in a closed loop to maintain the target air volume.

[0088] (3) Modular deployment process Fast assembly and disassembly: The main load-bearing frame can be assembled within 30 minutes through standardized interfaces, and the wind farm unit 300 and the control module can be plug-and-play through the plug-and-play interface; Scene switching: When working outdoors, the device moves to the designated location using its universal wheels, locks the wheels, and connects to a Power Bank 700 or generator. For indoor testing, it can be fixed to the ceiling rail using the hoisting interface to achieve multi-angle simulation.

[0089] In addition, this application also includes the following extended embodiments: 1. Scalable design: Reserved sensor interfaces (such as temperature, humidity, and air pressure sensors) support linkage with external data acquisition systems to achieve full simulation of environmental parameters; 2. Energy-saving optimization: Wind farm unit 300 uses a permanent magnet synchronous motor, with an efficiency of ≥90% when operating at less than full load, and a sleep mode to reduce standby power consumption; 3. Data recording: The signal controller 900 has a built-in SD card that stores wind farm parameters (wind speed, wind direction, operating time, etc.) in real time, supporting later data analysis and reproduction.

[0090] In summary, the beneficial effects of this application include but are not limited to the following: Mobility: Aluminum profile modular structure + universal wheels, supports quick disassembly and assembly within 30 minutes; Vertical wind direction control: double-layer rotatable deflector 400, continuously adjustable from 0° to +-45°; Wind farm independence: distributed control of 300+ independent wind farm units, supporting precise control of single units; Complex wind field simulation: dynamic control algorithm + multi-unit collaboration to reproduce transient fields such as gusts and turbulence; Safety: Independent safety switch 800+ overload protection.
