Description

Technical Field

[0001] This application relates to the field of wind power generation technology, and in particular to a wind power generation system and its control method and electronic equipment. Background Technology

[0002] With the global energy structure transitioning towards a low-carbon model, high-altitude wind energy has become an important development direction due to its advantages such as high wind speed and low turbulence. Existing high-altitude wind energy technologies mainly include tethered kites, tethered floating turbines, and balloon-guided systems. These solutions have proven their feasibility in demonstration applications, but the following key issues still exist: First, the dispersed direction of high-altitude winds and the lack of effective converging and guiding mechanisms in existing systems result in low effective wind speeds acting on the energy conversion units, limiting wind energy capture efficiency. Second, most systems employing reciprocating or traction-based power generation suffer from discontinuous energy conversion processes and high energy consumption during the recovery phase, leading to low overall conversion efficiency and large fluctuations in output power. Furthermore, cable systems, which simultaneously handle mechanical and energy transmission, are prone to fatigue and wear under dynamic loads and exhibit poor compatibility with ground-based power generation equipment, resulting in significant energy losses. Finally, these systems are relatively weak in high-altitude attitude control, tension regulation, and safety response, making it difficult to achieve stable and reliable long-term operation.

[0019] The following description, with reference to the accompanying drawings, illustrates an embodiment of a wind power generation system and its control method.

[0020] Figure 1 This is a schematic diagram of the structure of a wind power generation system provided in an embodiment of this application. Figure 2 This is a schematic diagram of another wind power generation system provided in an embodiment of this application. Figure 3 , Figure 4 , Figure 5 This is a schematic diagram of the air-filled air guide structure of a wind power generation system provided in this application under different operating modes, as shown in the embodiments. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the system includes: Inflatable air guiding structure, umbrella-shaped working unit, traction cable system, ground power generation and mechanical equipment, control and monitoring unit; The inflatable air guide structure is a floating body with a cavity, which is anchored to the ground by the edge anchor cable of the traction cable system. It is used to gather multi-directional airflow and guide it to a preset airflow channel. The umbrella-shaped working unit is arranged in sections along the central cable of the traction cable system. It can rise and fall along the central cable and open and close periodically, generating mechanical traction force by capturing airflow energy. The traction cable system connects the inflatable air guide structure, the umbrella-shaped work unit, and the ground power generation and mechanical equipment, and is used to transmit traction force and maintain the system attitude; Ground-based power generation and mechanical equipment receive mechanical energy transmitted by the umbrella-shaped work unit and convert it into electrical energy, while auxiliary mechanical devices are provided to ensure the operation of the system; The control and monitoring unit is connected to signals from other components to collect system operating parameters in real time, adjust the attitude of the inflatable wind guide structure, the opening and closing sequence of the umbrella-shaped working unit, and the tension of the traction cable to achieve stable and optimized energy conversion.

[0021] In this embodiment, the umbrella-type high-altitude wind power generation system is a device designed for efficient capture and stable conversion of high-altitude wind energy. Its core is composed of an inflatable wind guide structure, an umbrella-shaped power unit, a traction cable system, ground power generation and mechanical equipment, and a control and monitoring unit. Each component has a clear division of labor and works closely together.

[0022] As a buoyant structure with a cavity, the inflatable air guide structure can be filled with light inert gases such as helium and hydrogen, achieving high-altitude suspension through gas buoyancy. The outer edge of the structure is firmly anchored to ground anchor points or tension plates through the edge anchor cables of the traction cable system, which can resist high-altitude wind disturbances and maintain its own stable attitude. At the same time, it adopts a structure with good aerodynamic characteristics, such as a cooling tower shape, streamlined cylindrical shape, or trumpet shape, which can effectively gather dispersed airflow from different directions and unify the turbulent wind speed vector to the preset central airflow channel, providing concentrated and stable airflow power for subsequent energy capture.

[0023] The umbrella-shaped working unit is made of lightweight, high-strength, and flexible material. It is arranged in segments along the central cable of the traction cable system. Adjacent units can be designed with fixed or non-fixed spacing. Each unit is equipped with a mechanism that can open and close periodically. It can flexibly rise and fall along the central cable. When it opens under the action of airflow, it can fully capture airflow energy and convert it into mechanical traction force. When it closes, it reduces wind resistance to cooperate with the cyclic operation.

[0024] The traction cable system is the key to connecting the core components. It not only fixes the inflatable wind guide structure through the edge anchor cables, but its central cable also provides the lifting track for the umbrella-shaped working unit. At the same time, it undertakes the task of transmitting mechanical traction force, accurately transmitting the power generated by the umbrella-shaped working unit to the ground power generation and mechanical equipment. Furthermore, it helps to maintain the high-altitude attitude stability of the entire system through its own tension adjustment.

[0025] Ground-based power generation and mechanical equipment can take the form of drum-type power generation mechanism, linear generator or tension power generation mechanism, which can efficiently receive the mechanical energy transmitted by the umbrella-shaped work unit and convert it into electrical energy. At the same time, it is equipped with auxiliary mechanical devices such as tension compensation winch, brake, and take-up and release mechanism to ensure the continuous and smooth energy conversion process and meet the operating needs under different working conditions.

[0026] The control and monitoring unit connects to other components via signal lines, collecting real-time data on various system operating parameters such as wind speed, wind direction, cable tension, buoy attitude, and equipment operating temperature. Based on this data, it precisely controls the yaw angle and pitch attitude of the inflatable wind-guiding structure, the opening and closing sequence and amplitude of the umbrella-shaped working unit, and the tension of the traction cable to ensure coordinated operation of all components and achieve stability and optimization of the energy conversion process. Through the integrated design of its components, this system effectively improves the capture efficiency and utilization stability of high-altitude wind energy, reduces losses during energy conversion, and enhances the safety and reliability of system operation.

[0027] This application utilizes an inflatable air-guiding structure as a hollow buoyant body, anchored to the ground via edge anchor cables of a traction cable system. This structure gathers multi-directional airflow and guides it through a pre-defined airflow channel. Umbrella-shaped power units are segmented along the central cable of the traction cable system, capable of rising and falling along the central cable and periodically opening and closing, generating mechanical traction force by capturing airflow energy. The traction cable system connects the inflatable air-guiding structure, the umbrella-shaped power units, and ground-based power generation and mechanical equipment, transmitting traction force and maintaining system attitude. The ground-based power generation and mechanical equipment receives the mechanical energy transmitted by the umbrella-shaped power units and converts it into electrical energy, while also providing auxiliary mechanical devices to ensure system operation. A control and monitoring unit is connected to signals from other components to collect system operating parameters in real time, adjusting the attitude of the inflatable air-guiding structure, the opening and closing sequence of the umbrella-shaped power units, and the tension of the traction cables to achieve stable and optimized energy conversion. This application can solve the problems in related technologies such as insufficient wind energy gathering and guidance, poor structural stability, discontinuous energy conversion, low coupling efficiency between cables and ground power generation systems, and insufficient safety control capabilities, and achieve the technical effects of efficient high-altitude wind energy capture, stable and reliable system operation, and continuous, efficient, safe and controllable energy conversion.

[0028] In this embodiment, the inflatable air guide structure adopts a cooling tower-shaped or streamlined trumpet-shaped structure, which is made of multi-layer composite film material. The outer layer of the multi-layer composite film material is an anti-ultraviolet and tear-resistant polyester layer, and the inner layer is an aluminum gas barrier layer. The interior of the inflatable air guide structure is filled with a light inert gas to form buoyancy.

[0029] In this embodiment, the inflatable air guide structure, as the core component of the system's high-altitude buoyancy and airflow convergence, is specially designed with a cooling tower shape or a streamlined horn shape. This type of structure has excellent aerodynamic streamline characteristics, which can minimize high-altitude wind resistance. At the same time, it uses the structural contour to form a local negative pressure zone, which efficiently converges the dispersed airflow from different directions and guides the turbulent wind speed vector to the internal preset airflow channel, providing a concentrated and stable aerodynamic driving force for the subsequent umbrella-shaped working unit. This inflatable air-guiding structure is integrally molded from a customized multi-layer composite membrane material. The outer layer is made of UV-resistant and tear-resistant polyester. Polyester itself has high strength and tensile strength, and combined with a special tear-resistant weaving process, it can effectively resist the impact of external forces such as strong winds and sandstorms at high altitudes. At the same time, the added UV-resistant additives can block strong ultraviolet radiation at high altitudes, preventing the material from aging and becoming brittle after long-term exposure, thus extending the service life of the structure. The inner layer uses an aluminum gas-barrier interlayer. The aluminum layer has extremely high gas barrier properties, which can strictly prevent the infiltration and leakage of the internal filling gas, ensuring long-term stable buoyancy and preventing the structure from sinking or losing attitude due to gas loss. To achieve the high-altitude buoyancy function, the internal cavity of the inflatable air-guiding structure is filled with light inert gases such as helium and hydrogen. These gases have a density much lower than air, which can generate continuous and sufficient buoyancy, driving the entire air-guiding structure to smoothly rise to the working range at altitudes of hundreds to thousands of meters. Moreover, the chemical properties of inert gases are stable, and they are not prone to combustion, explosion, or other safety risks, making them suitable for the complex operating environment at high altitudes. The combination of the multi-layer composite membrane's double-layer structure and lightweight inert gas ensures the lightweight nature of the inflatable air guide structure, facilitating transportation and on-site deployment. Furthermore, the weather resistance of the materials and the airtightness of the gas guarantee the long-term reliable operation of the structure in high-altitude environments. Its unique streamlined structure further enhances airflow convergence and guidance efficiency, providing a fundamental guarantee for the overall power generation performance of the system.

[0030] In the embodiments of this application, the number of umbrella-shaped work units is at least two, and they are arranged at equal or non-equal intervals along the central cable. The umbrella-shaped work unit includes a flexible umbrella body and a support structure. The flexible umbrella body is made of high-strength nylon composite fabric or polyester composite fabric, and the support structure is a carbon fiber folded beam. The opening and closing mechanism of the umbrella-shaped working unit is either an active drive mechanism or a passive adaptive mechanism. The active drive mechanism is either a motor drive mechanism or a cylinder drive mechanism, while the passive adaptive mechanism achieves automatic opening and closing based on the wind pressure difference.

[0031] In this embodiment, the umbrella-shaped working unit serves as the core execution component for capturing high-altitude wind energy and converting it into mechanical traction force. The number of these units is set to at least two, arranged at equal or non-equal intervals along the central cable of the traction cable system. This multi-unit layout ensures the continuity and stability of energy capture, avoids power fluctuations during the operation of a single unit, and ensures that each unit is subjected to uniform force and that airflow utilization is more balanced, adapting to the stable wind speed environment at high altitudes. The non-equal interval arrangement optimizes the unit spacing according to the characteristics of the high-altitude wind profile, allowing airflow in different altitude ranges to be captured efficiently, further improving the overall wind energy utilization rate.

[0032] Each umbrella-shaped working unit consists of a flexible umbrella body and a supporting structure. The flexible umbrella body is made of high-strength nylon composite fabric or polyester composite fabric. These fabrics are lightweight, have high tensile strength, tear resistance, and strong weather resistance. They can maintain structural integrity in high-altitude strong wind environments, reduce the overall weight of the unit, reduce energy loss during ascent and descent, and meet the wear resistance and UV resistance requirements for long-term high-altitude operation. The supporting structure uses carbon fiber folding beams. Carbon fiber material has high strength per unit weight, excellent elastic modulus, and corrosion resistance. The folding beam design not only provides reliable support for the flexible umbrella body, ensuring a stable wind-receiving surface when the umbrella is open, but also allows for folding and storage when the umbrella is closed, reducing wind resistance and space occupation, facilitating a smooth recovery process, and reducing the difficulty of transportation and deployment.

[0033] The opening and closing mechanism of the umbrella-shaped power unit is divided into two categories: active drive mechanism and passive adaptive mechanism. The active drive mechanism is specifically a motor drive mechanism or a cylinder drive mechanism, which can precisely adjust the opening and closing timing and opening and closing amplitude of the umbrella body through the instructions of the control and monitoring unit, adapt to different wind speeds and wind direction changes, and achieve precise control of energy capture. The passive adaptive mechanism automatically opens and closes based on the wind pressure difference, without the need for additional power drive. When the wind pressure difference at the location of the umbrella body reaches the preset threshold, the umbrella surface automatically opens under the action of airflow, and naturally closes when the wind pressure difference decreases. It has a simple structure, high reliability, and can reduce failure points and maintenance costs.

[0034] This design, through a rational layout of multiple units, selection of high-quality materials, and flexible configuration of opening and closing mechanisms, effectively improves the wind energy capture efficiency, structural stability, and environmental adaptability of the umbrella-shaped power unit, providing key support for improving the overall energy conversion efficiency of the system.

[0035] In this embodiment of the application, the traction cable system includes an edge anchor cable and a center working cable; The edge anchor cables are arranged in a distributed manner to anchor the inflatable air guide structure and adjust its attitude; The central working cable is made of high-modulus polyethylene composite cable or aramid composite cable, and the two ends of the central working cable are respectively connected to the umbrella-shaped working unit and the ground power generation and mechanical equipment.

[0036] In this embodiment, the traction cable system is the core load-bearing component of the umbrella-type high-altitude wind power generation system, which is responsible for anchoring, attitude adjustment and energy transfer. Specifically, it includes two core components: the edge anchor cable and the center working cable. The two have a clear division of labor and work together to ensure the stable operation of the system at high altitude and efficient energy transfer.

[0037] The edge anchor cables are distributed evenly along the outer edge of the inflatable wind guide structure. Their number can be rationally determined based on the structure's size, weight, and high-altitude wind load characteristics to ensure balanced stress. One end of each edge anchor cable is securely connected to a pre-set connection point on the outer edge of the inflatable wind guide structure, while the other end is anchored to a ground anchor point or tension control device. By differentially adjusting the tension of each edge anchor cable, the yaw angle and pitch attitude of the inflatable wind guide structure can be precisely controlled. This effectively resists disturbances caused by high-altitude crosswinds or changes in wind direction, preventing lateral swaying or attitude deviation and ensuring the structure always maintains the optimal windward direction and stable buoyancy.

[0038] As a key channel for energy transfer, the central working cable is made of high-performance cable materials such as high-modulus polyethylene composite cable or aramid composite cable. High-modulus polyethylene composite cable has the characteristics of high strength per unit weight, strong fatigue resistance, friction and wear resistance and corrosion resistance, while aramid composite cable has excellent tensile strength and thermal stability. Both types of materials can adapt to the complex cyclic load environment at high altitudes and effectively withstand the tensile impact generated by the periodic opening and closing and lifting of the umbrella-shaped working unit.

[0039] One end of the central working cable is firmly connected to the umbrella-shaped working unit through a special connector to ensure that the traction force is transmitted without loosening. The other end is precisely connected to the power input end of the ground power generation and mechanical equipment, such as the force-bearing end of the drum or linear generator. This stably and efficiently transmits the mechanical traction force captured by the umbrella-shaped working unit from wind energy to the ground power generation equipment, realizing the conversion of mechanical energy into electrical energy.

[0040] This traction cable system, through reasonable structural division, scientific material selection and precise connection design, not only ensures the anchoring stability and attitude adjustability of the inflatable air guide structure, but also achieves efficient transfer of mechanical energy, significantly reducing energy loss and structural fatigue risk, and extending the service life of the system.

[0041] In this embodiment, the ground-based power generation and mechanical equipment includes a power generation device, an energy management module, and auxiliary mechanical devices; The power generation device is a drum generator, a linear generator, or a tension generator; The energy management module includes a rectifier, an energy storage unit, and a grid-connected inverter. The energy storage unit is a supercapacitor or a battery pack. Auxiliary mechanical devices include tension-compensating winches, brakes, and gas supply equipment.

[0042] In this embodiment, the ground power generation and mechanical equipment is the core ground unit in the umbrella-type high-altitude wind power generation system, which realizes the conversion of mechanical energy into electrical energy, ensures stable power output, and ensures the safe operation of the system. It integrates power generation devices, energy management modules, and auxiliary mechanical devices, with each component complementing each other and working together.

[0043] Among them, the power generation unit, as the core component of energy conversion, offers three options: drum generator, linear generator, or tension generator. The drum generator is suitable for high-tension, low-speed operating conditions. It drives the drum to rotate through the umbrella-shaped working unit pulling the central working cable, thereby driving the generator to operate and generate electricity, either directly connected or connected via a variable speed transmission belt or gearbox. The linear generator can directly convert the reciprocating linear displacement of the umbrella-shaped working unit into electrical energy, eliminating the intermediate transmission structure, reducing energy loss, and is suitable for large-stroke reciprocating operation scenarios. The tension generator achieves energy conversion based on the tension change of the central working cable, which can flexibly adapt to different tension fluctuation conditions and improve the system's adaptability to wind field changes.

[0044] The energy management module undertakes the critical tasks of power processing, storage, and grid connection. It includes a rectifier, energy storage unit, and grid-connected inverter. The rectifier can convert the unstable AC or DC power output from the generator into stable DC power, laying the foundation for subsequent processing. The energy storage unit uses supercapacitors or battery packs. Supercapacitors have the advantages of fast charging and discharging speed and long cycle life, which can quickly smooth out power fluctuations. Battery packs can store energy for a long time and release energy when wind speed is insufficient or grid connection demand is adjusted. The configuration of both on demand can ensure the continuity of power supply. The grid-connected inverter is responsible for converting the processed DC power into AC power that meets the grid standards. It also has a power factor correction function to reduce the impact of power on the grid and ensure stable grid connection.

[0045] Auxiliary mechanical devices ensure stable system operation. A tension-compensating winch adjusts the tension of the traction cable in real time to address dynamic changes in cable tension during the lifting and lowering of the umbrella-shaped working unit, preventing overload or underload from affecting system operation. The brake has a reliable braking and locking function, responding quickly to system shutdowns, emergencies, or cable abnormalities to prevent the umbrella-shaped working unit from going out of control and ensure structural safety. A gas replenishment device supplies light inert gas to the inflatable air-guiding structure to handle minor leaks, maintain stable buoyancy, and prevent structural subsidence. This design, through diversified selection and component coordination, achieves efficient energy conversion, stable storage, and safe grid connection, while simultaneously improving the system's operational reliability and adaptability to various conditions.

[0046] In this embodiment, the control and monitoring unit adopts a hierarchical control architecture, including a real-time control layer, a tactical dispatch layer, and a remote monitoring layer; The real-time control layer uses closed-loop control to adjust cable tension and parachute opening and closing actions. The tactical scheduling layer realizes the staggered operation scheduling of multiple umbrella-shaped power units based on short-term wind speed forecasts; The remote monitoring layer is used for remote monitoring, fault early warning, and interaction with the power grid; The control and monitoring unit is equipped with sensors including wind speed and direction sensors, cable tension sensors, buoy attitude sensors, and GPS altitude sensors.

[0047] In this embodiment, the control and monitoring unit serves as the core control hub of the umbrella-type high-altitude wind power generation system. It adopts a scientific and reasonable hierarchical control architecture, which includes a real-time control layer, a tactical dispatch layer, and a remote monitoring layer. Each layer performs its own function and works in coordination. At the same time, it is equipped with multiple types of dedicated sensors to provide comprehensive data support for the precise control and safe operation of the system.

[0048] The hierarchical control architecture addresses different control needs through hierarchical division of labor, ensuring real-time, strategic, and convenient regulation. The real-time control layer employs a closed-loop control mode, collecting key operational data such as cable tension and umbrella opening / closing status in real time via sensors. This data is fed back to the control core and compared with preset parameters. Based on deviations, adjustment commands are automatically generated to precisely regulate cable tension and umbrella opening / closing actions, ensuring force balance and smooth energy conversion within the umbrella-shaped work units. The tactical scheduling layer, based on short-term wind speed forecasts and the current system operating status, formulates staggered operation plans for multiple umbrella-shaped work units. The scheduling strategy, staggered operation, controls the opening and closing sequence and rising and falling rhythm of different umbrella-shaped power units to form a phase difference, avoiding power fluctuations caused by multiple units working or recovering power simultaneously, and ensuring the continuity and stability of ground power generation output. The remote monitoring layer has three core functions: remote monitoring, fault early warning, and grid interaction. Staff can view system operating parameters, equipment status, and other information in real time through remote terminals. The system can automatically analyze sensor data and issue fault early warning signals in a timely manner when abnormal parameters are detected. At the same time, this layer can interact with the grid system to adjust the system's power generation output according to the grid load demand, and achieve coordinated operation with the grid.

[0049] The control and monitoring unit is equipped with sensors including wind speed and direction sensors, cable tension sensors, buoyancy body attitude sensors, and GPS altitude sensors. The wind speed and direction sensors can simultaneously collect wind speed and direction data in the high-altitude working area and on the ground, providing a basis for the formulation of control strategies at each level. The cable tension sensors monitor the tension changes of the edge anchor cables and the central working cables in real time, and promptly report abnormalities such as overload or insufficient tension. The buoyancy body attitude sensors (such as IMU / tilt meter) can accurately capture attitude parameters such as yaw angle and pitch angle of the inflatable air guide structure, ensuring the accuracy of attitude adjustment. The GPS altitude sensor can locate the high-altitude position of the inflatable air guide structure and the umbrella-shaped working unit in real time, ensuring that the system always operates within the preset working height range.

[0050] This design achieves precise control over the entire process, from real-time execution to policy scheduling and remote monitoring, through a hierarchical control architecture. Combined with comprehensive data acquisition from dedicated sensors, it effectively improves the stability, controllability, and intelligence of the system, providing key guarantees for optimizing energy conversion efficiency and ensuring operational safety.

[0051] In this embodiment, a safety redundancy module is also included, which includes a multi-cavity separated inflation guide structure, a redundant brake, a spare drum, and an emergency recovery device. The multi-cavity independent sealing of the inflatable air guide structure ensures that leakage in a single cavity does not affect the overall buoyancy stability. The emergency recovery device can trigger the parachute to close and the system to descend in the event of extreme weather or cable malfunction.

[0052] In this embodiment, the safety redundancy module is the core guarantee unit for the umbrella-type high-altitude wind power generation system to ensure safe operation under extreme conditions and resist the risk of failure. Specifically, it includes an air-guiding structure with multiple air chambers, redundant brakes, a spare drum and an emergency recovery device. The components work together to form multiple safety protections, building a comprehensive defense line for the high-altitude operation of the system.

[0053] The multi-chamber inflatable air guide structure adopts a zoned independent sealing design, dividing the internal buoyancy cavity of the inflatable air guide structure into several independent sealed air chambers. Each air chamber is equipped with a dedicated sealing layer, inflation interface and leakage detection component. The air chambers are completely separated by an isolation structure and do not communicate with each other. This design ensures that even if a single air chamber leaks gas due to an accident, the remaining intact air chambers can still maintain sufficient buoyancy, preventing the inflatable air guide structure from becoming unstable and sinking, ensuring that the system attitude remains stable, and buying time for fault handling or emergency recovery.

[0054] The redundant brake serves as a dual safeguard for the braking system. It adds an independent backup braking mechanism in addition to the main brake. The backup mechanism uses a power source, control link, and execution components that are separate from the main brake. When the main brake fails to work properly due to wear, power interruption, or control failure, the redundant brake can be activated within a millisecond response time to firmly lock the cable or drum, preventing the umbrella-shaped working unit from falling uncontrollably due to braking failure.

[0055] The backup drum and the main drum are arranged in parallel, with independent drive motors, transmission gears and control modules. The backup drum shares the cable connection point with the main drum but maintains an independent transmission system. When the main drum jams, wears excessively or fails to drive, the control system can quickly switch to the backup drum to ensure that the cable winding and unwinding, traction force transmission and energy conversion processes are not interrupted, and to avoid system shutdown or equipment damage due to a single drum failure.

[0056] The emergency recovery device is a key actuator for responding to sudden dangerous working conditions. It integrates working condition monitoring sensors, command processing units and execution components, and can capture dangerous signals in real time such as extreme weather (such as thunderstorms, strong winds, hail) or cable abnormalities (such as sudden tension changes, excessive wear, and breakage warnings). Once the detected parameters reach the preset safety threshold, the linkage mechanism is immediately triggered: a retraction command is sent to the umbrella-shaped working unit to quickly reduce its wind-receiving surface. At the same time, the redundant brake and the backup drum are activated to control the cable to be recovered smoothly and at a constant speed. This drives the inflatable wind guide structure and the umbrella-shaped working unit to slowly descend to a safe height, avoiding damage to the equipment from extreme environmental impacts or falls from heights.

[0057] This safety redundancy module significantly improves the system's fault resistance and emergency response efficiency through its multi-cavity anti-instability design, redundant braking and backup drum for fault redundancy, and rapid-response emergency recovery mechanism. It effectively reduces the operational risks caused by air cavity leakage, mechanical failure and extreme weather, providing a solid guarantee for the long-term safe and reliable operation of the system.

[0058] Accordingly, embodiments of this application provide a control method for a wind power generation system, such as... Figure 6 As shown, the method includes: Step 101: A local negative pressure zone is formed at high altitude by an inflatable air guiding structure, which converges multi-directional airflow and guides it to a vertical airflow channel, thereby increasing the effective wind speed and reducing the turbulence of the airflow.

[0059] In some embodiments, the inflatable air guide structure, with its special structure design of cooling tower or streamlined trumpet shape, naturally forms a local negative pressure zone in the high-altitude environment: the outer contour of the structure has a gradually contracting shape. When high-altitude airflow from different directions comes into contact with the outer surface of the air guide structure, it will flow along the streamlined contour towards the center of the structure. As the flow cross section gradually shrinks, the airflow speed increases accordingly. According to the principle of fluid mechanics, the increase in flow speed will lead to a decrease in air pressure in the central area of ​​the structure, thereby forming a stable local negative pressure zone. This negative pressure effect will actively attract the surrounding dispersed multi-directional airflow, breaking the disordered distribution of airflow under natural conditions.

[0060] Meanwhile, the internal cavity channels of the air guide structure are aerodynamically optimized to guide the adsorbed and converged airflow to gradually adjust its direction, unifying and standardizing the wind speed vectors from different directions such as horizontal and oblique, ultimately guiding them into an airflow channel nearly perpendicular to the ground. This results in a concentrated and stable upward or downward airflow. In this process, the energy of the dispersed airflow is effectively aggregated, significantly increasing the effective wind speed. Actual simulations have verified that the local wind speed amplification factor can reach 1.3 to 1.8 times. Moreover, the standardized airflow reduces collisions and interference between each other, resulting in a decrease in airflow turbulence of approximately 35%. This provides a continuous and uniform aerodynamic driving force for the subsequent umbrella-shaped work unit and reduces the irregular impact of airflow turbulence on the system structure, laying the foundation for the system to stably capture wind energy.

[0061] Step 102: Control the umbrella-shaped power unit to open and close periodically along the central cable. During the ascent phase, the umbrella opens to capture airflow energy and generate traction. During the descent phase, the umbrella closes to reduce wind resistance and drives the ground power generation device through mechanical energy transmission.

[0062] In some embodiments, this step is the core execution link for the system to convert wind energy into mechanical energy and drive power generation. The real-time control layer of the control and monitoring unit precisely schedules at least two umbrella-shaped power units arranged at equal or non-equal intervals along the central cable according to wind speed, cable tension and system operating status, so as to realize the periodic opening and closing and lifting cycle along the central cable.

[0063] During the ascent phase, the control command triggers the opening and closing mechanism of the umbrella-shaped power unit. If it is an active drive mechanism (motor drive mechanism or cylinder drive mechanism), the umbrella is opened by power output; if it is a passive adaptive mechanism, the umbrella is automatically opened by the wind pressure difference. At this time, the flexible umbrella made of high-strength nylon composite fabric or polyester composite fabric forms a stable wind-receiving surface under the support of carbon fiber folding beams, fully capturing the vertical airflow energy after being gathered by the air-guiding structure. The continuous thrust of the airflow on the umbrella surface is converted into mechanical traction force upward along the central cable. This traction force is smoothly transmitted to the ground power generation and mechanical equipment through the central power cable made of high-modulus polyethylene composite cable or aramid composite cable.

[0064] When the umbrella-shaped power unit rises to the preset height or the tension of the central power cable reaches the set threshold, the system enters the descent phase. The control and monitoring unit issues a retraction command, and the opening and closing mechanism of the umbrella-shaped power unit responds quickly, causing the flexible umbrella to fold and retract. The carbon fiber folding beam then contracts, significantly reducing the wind resistance of the umbrella during descent. At this time, the umbrella-shaped power unit falls smoothly back along the central cable under the action of gravity and the auxiliary traction of the ground equipment. During the descent, the central power cable maintains stable tension transmission, further converting gravitational potential energy and residual airflow energy into mechanical energy.

[0065] Throughout the entire cycle, the central working cable continuously transmits the main traction force generated by the umbrella-shaped working unit during the ascent phase and the auxiliary mechanical energy during the descent phase to the ground power generation device. If it is a drum generator, the traction force drives the drum to rotate, which in turn drives the generator through a direct drive or variable speed transmission mechanism. If it is a linear generator, the reciprocating linear displacement of the umbrella-shaped working unit is directly converted into electrical energy. If it is a tension generator, the energy conversion is achieved by utilizing the change in cable tension. At the same time, multiple umbrella-shaped working units alternately enter the ascent opening and descent closing states through the staggered operation strategy of the tactical scheduling layer to avoid power output interruption.

[0066] Among them, the flexible umbrella material of the umbrella-shaped power unit has both lightweight and high strength characteristics, ensuring that it is not easily torn under stress and has low energy loss. The carbon fiber folded beam supports the umbrella without adding too much weight. The two types of opening and closing mechanism (active to ensure precise control and passive to improve structural reliability) are adapted to different wind field conditions, maximizing wind energy capture efficiency in the rising phase and minimizing wind resistance in the descending phase, effectively reducing non-power consumption. Through this periodic cycle, continuous and stable mechanical energy output is achieved, providing an efficient and continuous power source for ground power generation devices, significantly reducing the energy asymmetry problem of traditional reciprocating systems and improving net energy gain.

[0067] Step 103: Based on the dynamic tension adjustment of the distributed anchor cables, the attitude of the inflatable wind guide structure is monitored in real time. By adjusting the tension distribution of each edge anchor cable, lateral sway and yaw resonance are suppressed.

[0068] In some embodiments, distributed anchor cables refer to multiple edge anchor cables evenly distributed on the outer edge of the inflatable wind guide structure. One end of each anchor cable is firmly connected to a preset connection point on the outer edge of the wind guide structure, and the other end is independently anchored to a ground anchor point or tension control device, forming a multi-point force support system to ensure the all-round control capability of the wind guide structure's attitude. Dynamic tension adjustment is a closed-loop control method based on real-time attitude data, which realizes flexible adjustment of tension through the coordinated operation of control and monitoring units. Yaw resonance refers to the structural oscillation phenomenon caused by the periodic yaw swing of the inflatable wind guide structure coinciding with the system's natural frequency when excited by lateral wind or when the wind direction changes.

[0069] During execution, the control and monitoring unit, equipped with attitude sensors (such as IMUs / tilt meters), continuously collects attitude parameters of the inflatable wind-guiding structure, including yaw and pitch angles. Simultaneously, cable tension sensors monitor the current tension value of each edge anchor cable in real time. All data is transmitted to the real-time control layer for analysis. The real-time control layer compares the collected attitude parameters with preset stability thresholds (such as yaw angle ±5°). When a lateral swaying trend is detected in the wind-guiding structure, the yaw angle exceeds the allowable range, or the initial signal of yaw resonance is detected, a dynamic tension adjustment strategy is immediately activated. Based on the direction, amplitude, and pre-resonance characteristics of the attitude deviation, the controller accurately calculates the required tension adjustment for each edge anchor cable and implements differentiated adjustments for each anchor cable through a ground tension control device. For example, for the side of the wind-guiding structure that is deviating, the tension of the corresponding edge anchor cable is appropriately increased to create a reverse pull; the tension of the anchor cable on the other side is moderately reduced. Through this dynamic adjustment of tension distribution, a directional corrective torque is generated to counteract the disturbance force brought by the crosswind. Simultaneously, by adjusting the tension difference of different anchor cables, the force balance state of the inflatable wind guide structure is altered, thereby changing the system's natural frequency and preventing resonance with the frequency of wind disturbance, thus fundamentally suppressing the occurrence and aggravation of yaw resonance. This step, through multi-point support of distributed anchor cables and precise control of dynamic tension, effectively curbs the lateral swaying and yaw resonance of the inflatable wind guide structure, significantly improving the attitude stability of the wind guide structure in complex high-altitude wind fields, reducing safety hazards such as cable twisting and structural fatigue, and providing reliable assurance for the stability of subsequent airflow convergence and the efficient operation of the umbrella-shaped work unit.

[0070] Step 104: By using a hierarchical control strategy combined with a wind speed prediction model, the opening and closing timing of the umbrella-shaped power unit is optimized to match the torque of the ground power generation device, thereby achieving maximum power point tracking and output power smoothing.

[0071] In some embodiments, the three-layer architecture of the hierarchical control strategy performs its respective functions and works closely together. The real-time control layer, with a response speed of milliseconds to seconds, collects cable tension, umbrella operating status, and real-time generator output data through a closed-loop control mechanism. This data is combined with short-term wind field data provided by the wind speed prediction model (constructed based on LiDAR wind profile detection or IMU inertial measurement data, which can accurately predict wind speed change trends in the next few seconds to minutes) to dynamically adjust the opening and closing timing, opening and closing amplitude, and rising and falling rhythm of the umbrella-shaped power-generating unit. The tactical scheduling layer, based on the wind speed prediction results and the system... Based on the current power output status, a staggered operation scheduling scheme for multiple umbrella-shaped power units is formulated. By controlling the opening and closing phase difference of different umbrellas, the power peak superposition and valley gap caused by multiple units entering the power or recovery stage at the same time are avoided. At the same time, according to the predicted wind speed changes, some umbrellas are scheduled to start or stop in advance to ensure that the system always adapts to the energy supply of the wind farm. The remote monitoring layer is responsible for coordinating energy management and providing the power output benchmark to the tactical scheduling layer according to the grid interaction requirements and the status of energy storage units, ensuring that the torque matching is both in line with the wind energy capture efficiency and meets the grid connection requirements. The wind speed prediction model analyzes and processes historical operational data and real-time upper-level wind speed and direction data to predict wind field energy changes in advance, providing forward-looking guidance for optimizing the opening and closing sequence. When the predicted wind speed increases, the umbrella is controlled to open earlier and the opening and closing amplitude is increased, extending the power-operating phase. At the same time, the torque parameters of the ground power generation device (such as the drum torque of the drum generator and the magnetic circuit parameters of the linear generator) are adjusted to ensure that the torque is precisely matched with the traction force transmitted by the umbrella unit, avoiding excessive torque leading to cable overload or insufficient torque causing energy waste. When the predicted wind speed decreases, the power-operating phase of the umbrella is shortened in time, the closing timing is optimized to reduce non-power consumption, and the torque of the power generation device is adjusted down simultaneously to ensure dynamic balance between torque and traction force. In terms of maximum power point tracking (MPPT), the system employs an optimization strategy similar to MPPT. By defining the "power surface" of the reciprocating mechanism and combining real-time wind speed, cable tension, and power generation data, it searches online for the optimal opening and closing timing-torque matching combination, ensuring the system always operates at the point of highest wind energy utilization efficiency. Output power smoothing is achieved through a two-layer mechanism: first, the multi-umbrella staggered operation at the tactical scheduling layer, which allows the power output curves of each umbrella to overlap and offset fluctuations; second, the dynamic torque adjustment at the real-time control layer, which quickly responds to tension changes to smooth out instantaneous power peaks. Throughout the process, the layered control strategy ensures the real-time, accurate, and systematic nature of the regulation, while the wind speed prediction model avoids regulation lag caused by sudden wind field changes. The two work together to achieve an optimal match between the wind energy capture efficiency of the umbrella-shaped power unit and the energy conversion efficiency of the ground-based power generation device. This maximizes the utilization of high-altitude wind energy while keeping the output power fluctuation amplitude below 10%, significantly improving the system's grid compatibility and energy management efficiency.

[0072] This application provides another control method for a wind power generation system, such as... Figure 7 As shown, the method includes: Step 201: A local negative pressure zone is formed at high altitude by an inflatable air guiding structure, which converges multi-directional airflow and guides it to a vertical airflow channel, thereby increasing the effective wind speed and reducing the turbulence of the airflow.

[0073] Step 202: Control the umbrella-shaped power unit to open and close periodically along the central cable. During the ascent phase, the umbrella opens to capture airflow energy and generate traction. During the descent phase, the umbrella closes to reduce wind resistance and drives the ground power generation device through mechanical energy transmission.

[0074] Step 203: Based on the dynamic tension adjustment of the distributed anchor cables, the attitude of the inflatable wind guide structure is monitored in real time. By adjusting the tension distribution of each edge anchor cable, lateral swaying and yaw resonance are suppressed.

[0075] Step 204: Using a hierarchical control strategy combined with a wind speed prediction model, optimize the opening and closing timing of the umbrella-shaped power unit and the torque matching of the ground power generation device to achieve maximum power point tracking and output power smoothing.

[0076] For a description of steps 201-204, please refer to the description of steps 101-104 in the above embodiment. This embodiment will not repeat the details further.

[0077] Step 205: The control and monitoring unit detects cable tension fluctuations, umbrella opening and closing status, and gas pressure in the inflatable air guide structure in real time.

[0078] In some embodiments, the detection of cable tension fluctuations is achieved by deploying high-sensitivity cable tension sensors at key connection points between the edge anchor cable and the central working cable, cable end interfaces, and drum contact areas. These sensors can capture dynamic tension changes in the cable during different stages of the umbrella-shaped working unit's ascent and descent, including tension fluctuations under normal cyclic loads, as well as tension overloads and sudden tension changes caused by sudden wind speed changes or abnormal umbrella movements, accurately reflecting the cable's stress state. The detection of the umbrella's opening and closing state is accomplished by installing stroke sensors, angle sensors, or pressure sensors at the opening and closing mechanism of the umbrella-shaped working unit, the umbrella edge, and the connection point of the central cable. These sensors can collect data on the opening and closing of the umbrella in real time. The amplitude, opening and closing speed, and completion status of the opening and closing mechanism are all accurately captured, whether it's the execution effect of commands from the active drive mechanism (motor or cylinder drive) or the automatic opening and closing state of the passive adaptive mechanism based on wind pressure difference. This ensures that the actions of each umbrella-shaped working unit meet the system scheduling requirements. The detection of gas pressure in the inflation guide structure relies on gas pressure sensors and leakage detection sensors installed inside each independent air chamber, at the pressure compensation port on the upper part of the structure, and near the inlet and outlet valves. These sensors not only monitor in real time whether the overall gas pressure is maintained within the normal range to ensure buoyancy, but also, given the multi-chamber structure, individually detect the pressure data of each independent air chamber, promptly identifying minor leaks or pressure anomalies in a single air chamber. All parameter data collected by the sensors is transmitted in real time to the real-time control layer of the control and monitoring unit via signal lines. After data analysis and filtering, it is compared with preset safety thresholds and standard operating parameters to form intuitive status feedback, providing accurate data support for subsequent tension adjustment, umbrella movement correction, gas replenishment, and other control operations. This step, through comprehensive real-time monitoring of core operating parameters, can provide early warnings of potential risks such as cable overload, incomplete opening and closing of the parachute, and air chamber leakage, avoiding structural damage or operational failures caused by the failure to detect abnormal parameters in a timely manner, and laying a solid data foundation for the stable, safe, and efficient operation of the system.

[0079] Step 206: When abnormal cable tension fluctuation, parachute jamming, or gas leakage is detected, the partial shutdown diagnostic process is triggered, the backup drum is started to retrieve the cable, and the pressure of the air-guiding structure is compensated by the gas replenishment equipment.

[0080] In some embodiments, the control and monitoring unit continuously captures tension data of the central working cable and edge anchor cable through cable tension sensors. When irregular abnormal fluctuations in tension are detected (exceeding the normal operating fluctuation range), it is determined that the cable is under abnormal force. Through umbrella opening and closing status sensors and stroke sensors, if it is found that the umbrella-shaped working unit fails to complete the opening and closing action as instructed, or if there is jamming or inability to reach the preset position during the lifting and lowering process, it is determined that the umbrella is stuck. Through pressure sensors and leakage detection sensors of each independent air chamber of the inflation guide structure, if the air chamber pressure is detected to be continuously decreasing and exceeding the normal loss range, or if a gas leakage signal is detected, it is determined that there is a gas leakage. Once any of the above faults is identified, the system immediately triggers a partial shutdown diagnosis process—only suspending the local operating unit related to the fault (such as the umbrella corresponding to the abnormal cable connection, the local area where the leaking air chamber is located), rather than shutting down the entire system. At the same time, the fault diagnosis module is activated to analyze the fault type, location, and severity by combining historical sensor data and real-time operating parameters, providing accurate basis for subsequent maintenance. During this process, the backup reel starts simultaneously. This backup reel, arranged in parallel with the main reel and equipped with an independent drive motor, transmission gears, and control module, can quickly take over the cable retrieval task related to the fault, retrieving the corresponding cable at a stable speed. This avoids structural strain and damage caused by cable loss of control or parachute jamming, ensuring the safety of both the aerial equipment and ground installations. Simultaneously, the gas replenishment equipment (such as a small on-site compressor / air replenisher) automatically initiates a pressure compensation process based on gas leak detection results and pressure monitoring data: if a single air chamber leaks, the equipment precisely injects light inert gas through the chamber's dedicated inflation port to replenish the pressure loss; if the overall pressure drops slightly, the entire inflation guide structure is moderately replenished with gas to ensure that the pressure in each air chamber remains within a preset safe range, guaranteeing the buoyancy stability of the inflation guide structure and preventing instability or sinking due to insufficient pressure. This step, through partial shutdown diagnosis, avoids the escalation of the fault and the energy loss caused by the overall system shutdown. The timely intervention of the backup drum ensures the safe retrieval of the cable and umbrella body, while the pressure compensation of the gas replenishment equipment maintains the buoyancy of the air-guiding structure. The three work together to achieve rapid response and effective handling of the fault, significantly improving the system's fault resistance and emergency support level, reducing the impact of the fault on the system operation, buying time for subsequent fault investigation and maintenance, and ensuring the safety and reliability of the system's long-term operation.
