TECHNICAL FIELD
[0001] The present application relates to the technical field of wind power generation, in particular to a wind power generation system, a control method thereof, an electronic device and a storage medium. BACKGROUND
[0002] As a renewable energy with great development potential, wind energy is gradually extending to high altitude. The 300m-2000m region of high altitude has the advantages of high wind speed, low turbulence intensity and high energy density. Therefore, high altitude wind power generation technology has become an important direction of wind energy development.
[0003] In related technologies, high altitude wind energy utilization technologies mainly include kite type high altitude power generation, balloon type wind power device and cable traction type power generation system. The flight trajectory control of the kite type system is complex, is greatly affected by weather conditions and has high structural fatigue risk, and it is difficult to hover stably for a long time. The balloon type wind power device generally has the problems of insufficient buoyancy leading to limited operation height and weak wind resistance. In addition, the traditional balloon is usually in the shape of a simple drum or a sphere, and cannot form a stable wind channel, so that wind energy is difficult to be effectively gathered. The wind receiving units are unevenly affected by wind, and the wind speed is insufficient, so that the wind energy collection efficiency is low. The traditional horizontal axis wind turbine is significantly disturbed by crosswind in the high altitude flow field, and it is difficult to maintain stable orientation, so that the energy conversion efficiency is not high. At the same time, the traditional high altitude power generation device relies on a complex yaw system or a high-speed rotating blade to convert energy, and has a complex structure and is difficult to maintain. In addition, the attitude of the high altitude power generation structure is difficult to maintain under strong wind, and the operation stability is insufficient. The lifting control relies on the overall buoyancy or the change of flight attitude, and the control precision is low, so that it is difficult to achieve precise control. These problems limit the efficient development and utilization of high altitude wind energy. SUMMARY

[0020] The following description, with reference to the accompanying drawings, illustrates an embodiment of a wind power generation system and its control method.

Figure 2 , Figure 3 This is a schematic diagram of the air-guided and load-bearing structure of a wind power generation system provided in this application under different operating modes. Figure 4 , Figure 5 and Figure 6 This is a schematic diagram of the structure of a plate turbine unit of a wind power generation system under different operating modes, provided in an embodiment of this application. Figure 7 This is a schematic diagram of the plate unit structure of a plate-type unit provided in an embodiment of this application, as shown below. Figure 1 , Figure 2 , Figure 3 , Figure 4 ,Figure 5 , Figure 6 , Figure 7 As shown, the system includes: Air-guided and load-bearing structure, plate turbine unit, mooring and energy transmission subsystem, ground power generation and control station, and intelligent control and sensing subsystem; The air-guided and load-bearing structure includes an inflatable airbag, the lower part of which is equipped with a contractile air-guided structure to convert and concentrate the horizontal airflow at high altitude into an upwardly accelerating vertical airflow. The plate unit is installed inside the inflatable airbag and includes a wind-receiving component composed of multiple plate units that can rotate around an axis parallel to the ground, which is used to generate controllable lifting force under the action of vertical airflow. The plate-type unit is connected to the ground power generation and control station via tethering ropes in the tethering and energy transmission subsystem; The ground power generation and control station includes a winch and a generator. The winch is used to raise and lower the mooring rope, and the generator is used to convert the mechanical energy generated by the lifting and lowering motion of the plate unit into electrical energy. The intelligent control and sensing subsystem is used to monitor system status and environmental conditions, and optimize system power output and maintain stable operation by controlling the rotation angle of the control board unit and the torque or speed of the winch.
[0022] In this embodiment, the wind power generation system is composed of an aerial wind guide and load-bearing structure, a plate turbine, a mooring and energy transmission subsystem, a ground power generation and control station, and an intelligent control and sensing subsystem, forming a complete high-altitude wind energy collection and conversion system.
[0023] The core of the air-guided and load-bearing structure is an inflatable airbag. This airbag can be stably suspended at high altitudes and provide reliable load-bearing support. The contractile air-guided structure at its lower part adopts a specific contractile air duct design, which can guide the naturally existing horizontal airflow at high altitudes to enter from the lower inlet of the airbag. With the help of the contraction constraint of the air duct, the airflow direction gradually changes from horizontal to vertical upward. At the same time, the flow velocity is significantly increased during the contraction process, ultimately forming a stable and accelerated vertical airflow, providing high-quality wind energy input for subsequent energy conversion.
[0024] The plate unit is precisely positioned inside the inflatable airbag, exactly within the area affected by the vertical airflow. Its wind-receiving component is composed of multiple independent plate units. Both ends of each plate unit are rotatably connected to an axis parallel to the ground, allowing the plate unit to rotate flexibly around this axis. By adjusting the rotation angle of different plate units, the overall wind-receiving area and windward posture of the wind-receiving component can be changed, thereby generating a controllable lifting force under the action of the vertical airflow to meet the system's requirements for rising, hovering, or descending.
[0025] The plate-type unit establishes a stable connection with the ground power generation and control station through the tethering rope in the tethering and energy transmission subsystem. The tethering rope not only undertakes the mechanical traction and load-bearing functions of the plate-type unit, but also provides a basic channel for the system's energy and signal transmission.
[0026] The winch and tether rope in the ground-based power generation and control station are compatiblely installed, allowing for precise release and retraction of the tether rope based on the movement of the slab turbine unit. When the slab turbine unit rises under lifting force, it drives the winch to release the tether rope. The rotation of the winch directly drives the generator to operate, efficiently converting the mechanical energy obtained during the slab turbine unit's ascent into electrical energy. When the slab turbine unit descends, the winch can actively retrieve the tether rope. During this process, the generator can also achieve energy recovery and conversion, ensuring the full utilization of wind energy resources.
[0027] The intelligent control and sensing subsystem captures real-time system operating status data through various deployed sensing components, including the position, attitude, and tether rope tension of the plate unit. It also accurately monitors environmental wind conditions, such as wind speed, wind direction, and turbulence intensity. Based on this monitoring data, the subsystem precisely adjusts the rotation angle of each plate unit through preset control logic, ensuring that the wind-receiving components always maintain optimal wind conditions. At the same time, it reasonably controls the torque or speed of the winch to ensure smooth and orderly tether rope deployment and retraction. This not only effectively optimizes the system's power output efficiency but also maintains the stability of the entire system in complex and ever-changing high-altitude wind fields.
[0028] Through the coordinated design of its components, this system effectively solves the problems of insufficient wind flow convergence and unstable operation in traditional high-altitude wind power, and significantly improves wind energy utilization efficiency and operational reliability.
[0029] This application utilizes an air-guided and load-bearing structure including an inflatable airbag. The lower part of the inflatable airbag has a contractile air-guided structure to convert and concentrate high-altitude horizontal airflow into an upwardly accelerating vertical airflow. A plate-type turbine unit is housed inside the inflatable airbag and includes a wind-receiving assembly composed of multiple plate units that can rotate around an axis parallel to the ground, used to generate controllable lift force under the influence of the vertical airflow. The plate-type turbine unit is connected to a ground-based power generation and control station via a tethering rope in a tethering and energy transmission subsystem. The ground-based power generation and control station includes a winch and a generator. The winch is used to raise and lower the tethering rope, and the generator converts the mechanical energy generated by the lifting and lowering motion of the plate-type turbine unit into electrical energy. An intelligent control and sensing subsystem monitors the system status and environmental wind conditions, and optimizes system power output and maintains stable operation by controlling the rotation angle of the plate units and the torque or speed of the winch. This application can solve the problems in related technologies, such as the difficulty in effectively converging and introducing airflow into the energy conversion unit, the difficulty in maintaining the posture of the suspended power generation structure, the reliance on complex structures for energy conversion and low efficiency, and the insufficient precision of lifting and lowering control. It can achieve the technical effects of improving airflow convergence efficiency, enhancing system operation stability, improving energy conversion efficiency, and realizing precise and controllable lifting and lowering and power output.
[0030] In this embodiment, the retractable air guide structure of the inflatable airbag includes guide vanes and a rectifier ring disposed at the lower opening of the airbag. The installation angle of the guide vanes is adjustable to form an acceleration air duct with a preset contraction ratio, so that the vertical outlet wind speed gains an increase relative to the horizontal inlet wind speed.
[0031] In this embodiment, the core of the inflatable airbag's contractile air-guiding structure consists of guide vanes and a rectifier ring located at the lower opening of the airbag. These two components work together to guide and accelerate the horizontal airflow at high altitudes. The rectifier ring is a ring-shaped structure, coaxially mounted at the inlet end of the airbag's lower opening. Its main function is to pre-regulate the horizontal airflow entering the airbag, reducing turbulence and disturbance at the inlet and ensuring a smooth flow into the subsequent guiding area. The guide vanes are evenly distributed circumferentially along the rectifier ring. One end of each guide vane is fixed to the edge of the rectifier ring or the lower opening of the airbag via a rotatable connector, allowing the guide vanes to rotate flexibly around the connection point, thus enabling on-demand adjustment of the installation angle. By changing the tilt angle of the guide vanes, the cross-sectional shape of the air-guiding channel can be flexibly adjusted, thereby forming an accelerated airflow channel with a preset contraction ratio. When the guide vanes tilt inwards towards the channel, the cross-section of the airflow channel gradually contracts from the inlet to the outlet. The contraction ratio can be adjusted to any value between 1.5 and 2.3 according to actual wind conditions. Guided by the rectifier ring, the high-altitude horizontal airflow enters the contraction duct. Due to the continuous contraction of the duct cross-section, the airflow is compressed, its kinetic energy accumulates, and its velocity gradually increases along the duct axis. Finally, when it exits through the vertical outlet inside the airbag, the vertical outlet velocity achieves a significant gain relative to the horizontal inlet velocity, with a gain ratio of 1.3 to 1.8 times. This adjustable contraction-type air guide structure can adapt to horizontal winds of different heights and intensities, always maintaining the optimal contraction state of the duct to ensure the stability and acceleration effect of the vertical airflow. It effectively solves the problem that traditional airbags cannot rectify airflow, significantly improving wind energy convergence efficiency and wind speed quality, providing a stable and efficient aerodynamic environment for the plate-type turbine unit inside the airbag, and helping the system obtain reliable wind energy input even at lower natural wind speeds.
[0032] In this embodiment of the application, in the plate unit, both ends of each plate unit are connected to the support frame through a servo driver with angle feedback. The servo driver can drive the plate unit to rotate within a preset angle range and precisely lock the angle, where 0 degrees corresponds to the plate surface being horizontal to generate maximum lift, and 90 degrees corresponds to the plate surface being vertical to allow airflow to pass through.
[0033] In this embodiment, each plate unit of the plate-type unit is stably assembled with the support frame through connection structures at both ends. The core connecting component is a servo driver with angle feedback function. One end of the driver is fixed to a preset mounting position on the support frame, and the other end is precisely connected to the end shaft of the plate unit, forming a complete drive and feedback link. The plate unit is in the form of a long strip of thin plate with rotary bearing seats at both ends; the plate surface can be a flat plate or a curved surface with a slight aerodynamic curvature to improve the lift coefficient.
[0034] Its materials are lightweight and high-strength composite materials (such as carbon fiber / glass fiber composites that are heat-cured epoxy resins) or high-performance engineering plastics (such as polyamide reinforced composites), with a UV-resistant weather-resistant coating on the surface.
[0035] The servo drive incorporates an angle detection element, enabling real-time capture of the plate unit's rotation angle information and forming a closed-loop feedback to ensure precise angle control. It can drive the plate unit to rotate flexibly within a preset range of 0 to 180 degrees, with smooth rotation and rapid response. Once the plate unit reaches the target angle, the servo drive precisely locks it via a built-in locking mechanism, preventing angle deviation due to high-altitude airflow disturbances or mechanical vibrations, thus ensuring operational stability. In the 0-degree state, the plate unit's surface is horizontally arranged, maximizing the absorption of the upward-accelerating vertical airflow from the inflatable airbag. The pressure difference generated by the airflow on the plate surface reaches its maximum, converting into maximum lift and providing sufficient power for the plate unit's upward movement. In the 90-degree state, the plate unit's surface is vertically arranged, parallel to the airflow direction. The airflow can smoothly pass through the gaps between the plate units without generating effective lift, allowing the plate unit to descend smoothly under the combined effect of its own weight and the tension of the tethering rope. This servo drive and locking design with angle feedback provides the plate unit's angle adjustment with extremely high controllability and repeatability. It effectively solves the problems of low angle adjustment accuracy and unreliable locking of traditional wind-receiving structures, realizes precise control of lift, ensures stable and controllable lifting and lowering movement of plate turbine units, and improves energy conversion efficiency and system operation reliability.
[0036] In this embodiment of the application, the tether rope in the tethering and energy transmission system is made of high-strength fiber material. It has a cable winch for power return and data transmission integrated inside or outside, which is directly driven by the generator or connected through a transmission mechanism. It also has a regenerative brake that can recover energy during the descent phase of the platen unit.
[0037] In this embodiment, the tether rope in the tethering and energy transmission system is made of high-strength fiber material, specifically UHMWPE (such as Dyneema / Spectra) or aramid (such as Kevlar), which possess high tensile strength, low density, excellent fatigue resistance, and good UV resistance. This material can stably support the weight of the tethered unit and withstand the traction force from high-altitude winds, while effectively reducing the impact of its own weight on system operation. To achieve the integration of power return and data transmission, dedicated cables are integrated inside or outside the tether rope. When integrated internally, the cable is coaxially arranged with the rope core; when integrated externally, it is fixed parallel to the tether rope. The cables are flexible high-voltage cables or optical fibers. The high-voltage cables can adopt a multi-core design and a layered protection structure for the current-carrying conductor, or use high-voltage direct current (HVDC) to reduce energy transmission loss. The optical fibers ensure high-speed and stable data transmission, guaranteeing signal communication between ground and airborne equipment. The winch, working in conjunction with the tether rope, is connected to the generator via a direct drive or a transmission mechanism. The direct drive connection reduces frictional losses in intermediate transmission links, improving energy transfer efficiency. The transmission mechanism connection allows the gearbox to adapt to different lifting and lowering speeds of the turbine and the generator's optimal speed range, ensuring efficient adaptation during power generation. The winch also integrates a regenerative brake, which works in conjunction with the generator. When the turbine enters the descent phase, the unit, under its own weight and the tension of the tether rope, drives the winch to rotate in the opposite direction. At this time, the regenerative brake activates, converting the mechanical energy generated during the descent into electrical energy through the generator and storing it, thus avoiding energy waste. The beneficial effects are that the high-strength tether rope ensures the reliability and durability of the system connection, the integrated cable simplifies the transmission structure, the direct drive or transmission connection improves energy transfer efficiency, and the regenerative brake enables energy recovery during the descent phase, significantly improving the overall wind energy utilization rate of the system.
[0038] In this embodiment, the intelligent control and sensing subsystem includes wind speed and direction sensors arranged on the top of the airbag, near the platen unit, and on the ground; an inertial measurement unit for measuring the attitude of the platen unit; a tension sensor for measuring the tension of the tether rope; and an angle encoder for measuring the rotation angle of the platen unit. The controller in the intelligent control and sensing subsystem is configured to execute a preset model predictive control algorithm. The algorithm aims to maximize net power generation while using tether rope tension and structural fatigue as constraints to dynamically solve for the optimal platen unit angle combination and winch torque command sequence.
[0039] In this embodiment, the intelligent control and sensing subsystem constructs a comprehensive and high-precision monitoring and control system. Its sensor deployment covers core aspects such as wind field, equipment attitude, rope tension, and actuator status. Wind speed and direction sensors are arranged in zones: sensors on the top of the airbag capture real-time wind speed and direction reference information of the overall high-altitude wind field; sensors near the tractor unit focus on local airflow changes, accurately sensing airflow parameters acting on the wind-receiving components; and ground sensors collect near-ground wind condition data, providing reference and correction for global wind field analysis. The three work together to achieve full-dimensional monitoring of the wind field. An inertial measurement unit (IMU) for measuring the attitude of the tractor unit is integrated into the main structure of the unit, with a built-in three-axis accelerometer and three-axis gyroscope. It can capture the pitch angle, roll angle, yaw angle, linear velocity, angular velocity, and other attitude parameters of the unit in real time, accurately reflecting the motion state of the unit in the high-altitude wind field. A tether rope tension sensor is installed at the connection end between the tether rope and the tractor unit or at the ground winch, which can collect real-time tension data of the rope at high frequency and promptly report changes in rope tension. An angle encoder corresponds one-to-one with the drive mechanism of each plate unit, enabling precise measurement of the plate unit's rotation angle and providing reliable data support for closed-loop control of the plate angle. The core controller of this subsystem pre-stores a model predictive control algorithm. This algorithm aims to maximize the system's net power generation while limiting the tethering rope tension within a safe threshold and reducing structural fatigue loss as key constraints. The controller dynamically constructs a system operation model by fusing monitoring data collected from various sensors in real time. Within a preset prediction time window, the algorithm dynamically solves for the optimal plate unit angle combination and winch torque command sequence, ensuring precise matching of control commands with real-time wind conditions and system status. Its beneficial effects include achieving precise perception of wind field and system status and dynamic optimization of control strategies, maximizing power generation efficiency while ensuring safe and stable system operation, and significantly improving the system's adaptability to complex wind fields.
[0040] In this embodiment, the controller is also configured to execute a graded fault response strategy: when a single sensor fault is detected, switch to a backup sensor and reduce the control bandwidth; when a single board unit drive fault is detected, lock the faulty board unit and recalculate the control allocation of the remaining board units; when an airbag leak is detected or the wind speed exceeds a safety threshold, control all board units to turn to a vertical state and initiate the winch emergency braking and airbag depressurization procedure to perform system emergency recovery.
[0041] In this embodiment, the controller is also equipped with a comprehensive hierarchical fault response strategy, which can accurately execute corresponding handling schemes according to the fault type and severity, ensuring the safety and controllability of the system under different fault scenarios. When the controller detects a single sensor failure through sensor feedback signals, it immediately activates the redundancy protection mechanism, switches to the pre-deployed backup sensor to continuously acquire key monitoring data, avoids monitoring interruption due to single sensor failure, appropriately reduces the control bandwidth, reduces data processing load, avoids the generation of invalid commands, ensures the system maintains normal operation under basic control accuracy, and synchronously reports fault information for subsequent maintenance; when a fault is detected in the drive mechanism of a single board unit, the controller quickly sends a locking command to the faulty board unit, fixing the faulty board unit in a safe position (such as vertical position) that does not interfere with the overall airflow through its built-in electromagnetic brake or mechanical latch, preventing the disorderly rotation of the faulty board unit from disrupting the system's force balance, and then, based on the performance parameters of the remaining normal board units, the current wind field conditions, and the system's operating objectives, restarts the system. The system recalculates and allocates control commands to each normal plate unit, adjusting their rotation angle and synchronization logic to ensure the plate turbine can still generate stable lifting force. The system continues power generation in degraded mode and prompts for timely maintenance. When the airbag chamber pressure sensor detects airbag leakage, or the wind speed sensor detects that the ambient wind speed exceeds a preset safety threshold, the controller determines it as a serious fault. It immediately issues commands to all plate units, controlling them to quickly switch to a vertical position, significantly reducing air resistance and lift. Simultaneously, it activates the winch's mechanical emergency braking device, locks the mooring rope to prevent uncontrolled retrieval, and simultaneously triggers the airbag's automatic pressure relief valve and redundant safety valve, slowly releasing gas from the airbag to reduce wind exposure and buoyancy. The system's emergency recovery procedure is then initiated, safely lowering the plate turbine and airbag to a low altitude or to the ground, preventing further damage from strong winds or airbag instability. This tiered fault response strategy enables precise adaptation to different levels of faults, ensuring continuous system operation during minor faults and rapidly activating safety protection during serious faults. This significantly improves system reliability and safety, minimizing fault losses.
[0042] Accordingly, embodiments of this application provide a control method for a wind power generation system, such as... Figure 8 As shown, the method includes: Step 101: The natural horizontal wind is gathered and accelerated into an upward vertical airflow through the air guide structure of the inflatable airbag.
[0043] In some embodiments, the inflatable airbag adopts a hollow structure in the shape of a cooling tower or a truncated cone. Its shape, which narrows at the bottom and widens at the top, provides basic morphological support for airflow guidance. This structure can naturally receive horizontal winds from all directions at high altitudes, avoiding excessive flow losses around the airbag. The core of the airbag's air guiding structure consists of a rectifier ring and guide vanes located at the bottom. The rectifier ring is installed coaxially at the bottom inlet of the airbag, which can pre-regulate the horizontal airflow entering the airbag, weaken the turbulent components in the airflow, reduce the turbulent collisions at the inlet, and ensure that the airflow can enter the subsequent guiding channel smoothly and orderly. The guide vanes are evenly distributed around the circumference of the rectifier ring and are fixed to the rectifier ring or the edge of the bottom of the airbag through rotatable connectors. Their installation angle can be flexibly adjusted according to the actual wind conditions, thereby forming a contraction-type air duct with a preset contraction ratio (1.5~2.3). When natural horizontal wind encounters the lower opening of the airbag, it first forms a stable incoming airflow under the guidance of the rectifier ring. Then, it enters the contracting duct formed by guide vanes. As the duct cross-section gradually contracts from the inlet to the outlet, the airflow is subjected to continuous compression, and its kinetic energy accumulates. Simultaneously, guided by the guide vanes, the airflow direction gradually changes from horizontal to vertically upward, ultimately forming a directional vertical airflow that exits from the upper opening of the airbag. During this process, thanks to the structural design of the contracting duct, the vertical outlet wind speed achieves a significant gain relative to the horizontal inlet wind speed, with a gain factor of 1.3 to 1.8 times, effectively converging and accelerating the natural horizontal wind. This process, through the morphological design of the guide structure and component coordination, fully utilizes fluid dynamics principles to convert dispersed horizontal wind energy into concentrated, high-speed vertical airflow, providing a stable and efficient aerodynamic environment for subsequent energy conversion components and significantly improving the utilization efficiency of wind energy.
[0044] Step 102: Based on the vertical airflow conditions, control the rotation angle of multiple plate units in the plate unit set inside the airbag to adjust the overall wind-receiving area and lift coefficient, thereby driving the plate unit to perform lifting and lowering movements.
[0045] In some embodiments, the plate unit is precisely positioned in the central area inside the inflatable airbag, precisely within the core area of the vertical airflow transformed by the air guide structure. Its air-receiving component is composed of multiple independent plate units spliced together by a support frame. Each plate unit has two ends rotatably connected to an axis parallel to the ground. The drive mechanism at the connection point can accurately respond to control commands, driving the plate unit to rotate flexibly within a preset angle range. The system uses wind speed sensors deployed inside the airbag and around the plate unit to capture key wind condition parameters such as the wind speed and turbulence intensity of the vertical airflow in real time. These parameters serve as the core basis for adjusting the angle of the plate unit, directly guiding the lift control logic. When the vertical airflow speed is too high, to avoid excessive lift causing the plate unit to rise too quickly, the controller will instruct some or all of the plate units to rotate vertically, reducing the angle between the plate surface and the airflow direction, thereby reducing the overall effective air-receiving area and lowering the lift coefficient. When the vertical airflow speed is too low, the controller controls the plate units to rotate horizontally, increasing the air-receiving area to improve the lift coefficient and ensure sufficient upward momentum. The rotation angle of the plate unit is continuously adjustable from 0 to 180 degrees. At 0 degrees, the plate surface is horizontal, maximizing the wind-receiving area and reaching its peak lift coefficient, generating the strongest lift. As the rotation angle gradually increases, the angle between the plate surface and the vertical airflow gradually decreases, the effective wind-receiving area continuously shrinks, and the lift coefficient decreases accordingly. When rotated to 90 degrees, the plate surface is vertical, the effective wind-receiving area is minimized, and the lift approaches zero. By coordinating the rotation angles of all plate units, precise control of the overall wind-receiving area and lift coefficient can be achieved. When the adjusted lift is greater than the sum of the plate unit's own weight and the tension of the mooring rope, the plate unit moves upward; when the lift is less than the sum of these forces, the plate unit moves downward under the combined action of its own weight and the tension of the mooring rope, thus stably driving the plate unit to complete its lifting and lowering motion. This process can adapt to fluctuations in vertical airflow, allowing the lifting and lowering states of the platen unit to precisely match the wind conditions. The beneficial effect is that it significantly improves the adaptability of the platen unit to wind conditions, ensures the smooth and controllable lifting and lowering motion, and lays a stable mechanical motion foundation for the subsequent efficient conversion of mechanical energy into electrical energy.
[0046] Step 103: The lifting motion is transmitted to the winch and generator on the ground through the mooring rope connecting the plate generator unit and the ground power station, so as to convert mechanical energy into electrical energy.
[0047] In some embodiments, a stable and efficient connection is established between the slab generator and the ground power station via a tether rope. This tether rope is made of high-strength fiber material, possessing excellent tensile strength, low density, and fatigue resistance. It reliably supports the weight of the slab generator and the traction force generated by its lifting motion, while avoiding excessive energy loss due to its own weight. Simultaneously, it integrates power return cables internally or externally, providing a channel for power transmission. When the slab generator rises under the influence of vertical airflow, the mechanical energy it gains is directly transferred to the winch on the ground via the tether rope, causing the winch to rotate synchronously. The winch and generator are coupled together; a direct-drive connection can be selected to reduce transmission losses, or a gearbox can be used to adapt to different lifting speeds and the optimal speed range of the generator. The generator is preferably a permanent magnet synchronous generator, possessing high efficiency and wide speed adaptability, capable of rapidly converting the mechanical energy generated by the winch rotation into electrical energy. When the wind turbine enters the descent phase, the ground control module instructs the winch to actively reel in the rope. The winch's rotation also drives the generator. Simultaneously, regenerative braking technology converts the gravitational potential energy and airflow force released during the descent into electrical energy, achieving energy recovery and avoiding waste. The electricity generated by the generator is rectified and inverted; part of it can be directly connected to the grid for power supply, while the other part is stored in the battery bank to smooth power fluctuations during generation and ensure stable power output. The entire energy conversion process is achieved through direct mechanical linkage, eliminating the need for complex intermediate conversion links, resulting in high transmission efficiency and reliable operation. The benefits include efficient conversion of high-altitude wind energy into electrical energy and energy recovery during the descent phase, significantly improving wind energy utilization. Furthermore, the structure is simple, maintenance is convenient, and the continuity and stability of power output are guaranteed.
[0048] Step 104: Using the intelligent control module, real-time sensor data and wind speed prediction information are integrated, and an optimized control algorithm is used to dynamically coordinate the angle adjustment of the plate unit and the torque or speed control of the winch, so as to maximize power generation and ensure stable system operation.
[0049] In some embodiments, the intelligent control module, as the core control hub of the entire wind power generation system, collects complete data from various sensing devices in real time. This includes wind field parameters such as real-time wind speed, wind direction, and turbulence intensity captured by wind speed sensors distributed on the top of the airbag, around the slab unit, and on the ground; attitude data such as pitch angle, roll angle, and linear velocity of the slab unit fed back by the inertial measurement unit (IMU); real-time force information of the rope obtained by the tether rope tension sensor; and precise angle data transmitted by the angle encoders of each slab unit. At the same time, it combines the wind speed prediction information obtained by fusing short-time series prediction methods with wind field detection data to comprehensively grasp the current system operating status and the trend of wind condition changes in the near future. Based on this fused multi-dimensional data, the intelligent control module employs a pre-set optimized control algorithm. This algorithm prioritizes maximizing power generation while using key constraints such as limiting tether rope tension within a safe threshold and reducing structural fatigue losses. Through dynamic modeling and iterative calculations, it generates an optimal control strategy: on one hand, it precisely adjusts the rotation angle of each plate unit to ensure the wind-receiving area and angle of attack of the plate turbine are always adapted to real-time wind conditions, fully capturing the energy of vertical airflow to generate stable lifting force; on the other hand, it flexibly adjusts the torque or speed of the winch to ensure precise synchronization between the tether rope's winding and unwinding speeds and the plate turbine's lifting and lowering movements, avoiding system vibration caused by sudden tension changes or speed mismatches. During operation, the algorithm continuously optimizes control commands based on dynamic changes in real-time sensor data and wind speed prediction information, achieving real-time coordination between plate unit angle adjustment and winch control. This ensures that energy conversion efficiency remains at an optimal level while effectively resisting the uncertainties of high-altitude wind fields, maintaining the stability of the system's attitude and operating status. The beneficial effect is that, through precise control of data fusion and optimization algorithms, the system's ability to adapt to complex wind fields is significantly improved, maximizing power generation efficiency while ensuring operational safety, and greatly enhancing the system's stability and reliability.
[0050] This application provides another control method for a wind power generation system, such as... Figure 9 As shown, the method includes: Step 201: The natural horizontal wind is gathered and accelerated into an upward vertical airflow through the air guide structure of the inflatable airbag.
[0051] Step 202: Based on the vertical airflow conditions, control the rotation angle of multiple plate units in the plate unit set inside the airbag to adjust the overall wind-receiving area and lift coefficient, thereby driving the plate unit to perform lifting and lowering movements.
[0052] Step 203: The lifting motion is transmitted to the winch and generator on the ground through the mooring rope connecting the plate generator unit and the ground power station, so as to convert mechanical energy into electrical energy.
[0053] Step 204: Using the intelligent control module, real-time sensor data and wind speed prediction information are integrated, and an optimized control algorithm is used to dynamically coordinate the angle adjustment of the plate unit and the torque or speed control of the winch, so as to maximize power generation and ensure stable system operation.
[0054] 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.
[0055] Step 205: Monitor the system status in real time and determine the fault level.
[0056] In some embodiments, the system captures the operating status of the entire system in real time through various sensors deployed in the intelligent control and sensing subsystem. The monitoring range covers core components and key parameters: the pressure of each compartment of the inflatable airbag is collected in real time by pressure sensors; the rotation angle of each plate unit of the plate unit is accurately fed back by angle encoders; the attitude of the unit is continuously tracked by an IMU integrating a three-axis accelerometer and a gyroscope; the real-time tension of the tether rope is monitored by both rope end force sensor and winch torque sensor; and the operating current and response speed of the drive mechanisms such as servo driver and winch motor, as well as the signal transmission integrity of all sensing devices are monitored synchronously. These multi-dimensional monitoring data are continuously transmitted to the central controller. The controller performs real-time analysis and status assessment based on preset normal operating thresholds, data fluctuation ranges, and anomaly judgment rules: a minor fault is identified when a single sensor detects signal interruption or data drift, but a backup sensor can immediately switch and provide valid data, and the core system functions are unaffected; a moderate fault is identified when a single board unit's servo driver fails to respond, the board unit angle cannot be adjusted as instructed, or the tether rope tension exhibits a continuous small anomaly but does not exceed the safety limit; a serious fault is identified when the airbag chamber pressure drops rapidly in a short period (indicating airbag leakage), the wind speed sensor detects an ambient wind speed exceeding the safety threshold of 1.5 times the designed operating wind speed, or the tension of multiple tether ropes simultaneously spikes to a dangerous range. This entire process achieves comprehensive, uninterrupted monitoring of the system status and rapid, accurate fault level determination. The beneficial effect is that it provides timely and reliable decision-making basis for subsequent graded fault responses, minimizing fault handling time, reducing the risk of fault escalation, and ensuring system operational safety.
[0057] Step 206: If it is a Level 1 fault, enable redundant data sources and reduce the response bandwidth of the control system.
[0058] In some embodiments, when the system detects anomalies such as single sensor signal interruption, data drift, or a Level 1 fault that does not affect the core power generation function (e.g., local limit triggering), the control system immediately activates a preset response mechanism. Redundant data sources refer to backup sensors pre-deployed for key monitoring parameters such as wind speed, plate unit angle, and mooring rope tension. After identifying a primary sensor failure through signal verification, the controller quickly switches to the backup sensor to acquire valid monitoring data. Simultaneously, it integrates auxiliary data from other relevant sensors for cross-validation, ensuring the continuity and accuracy of monitoring data and preventing monitoring gaps due to single sensor failure. Furthermore, the control system proactively reduces the response bandwidth by appropriately decreasing the data sampling frequency and control command update rate, reducing the load on data processing and command interaction, and avoiding invalid control actions. At the same time, it retains the basic response capability of the core control loop, ensuring the stability of key operations such as plate unit angle adjustment and winch tension control, without affecting the overall system operation rhythm. Redundancy backup ensures uninterrupted monitoring data, reduces bandwidth to avoid system fluctuations, and achieves continuous and stable system operation under Level 1 faults, minimizing the impact of faults on power generation efficiency.
[0059] Step 207: If it is a level 2 fault, isolate the faulty component and adjust the control parameters of the remaining components to maintain degraded operation.
[0060] In some embodiments, when the system determines a level-two fault (such as a fault in the drive mechanism of a single plate unit or a minor rope abnormality), the controller immediately activates the faulty component isolation mechanism: if a single plate unit drive fault is detected, a locking command is immediately sent to the faulty plate unit, which is then fixed in a vertical and safe position by its built-in electromagnetic brake or mechanical latch, preventing the disorderly rotation of the faulty plate unit from interfering with airflow and the overall force balance of the system, thus achieving physical isolation between the faulty component and the normal component; if it is a minor rope abnormality, the tension sensor continuously tracks the rope stress state, defines a safe tension fluctuation range, and limits the further transmission of abnormal tension. Subsequently, the controller dynamically adjusts the control strategy based on the current real-time wind field data, the performance parameters of the remaining normal components, and the system's preset power generation target: for plate turbine units, the rotation angle and opening and closing sequence of the remaining normal plate units are redistributed through model predictive control algorithms to optimize the wind-receiving area and lift combination, compensating for the lift loss caused by the faulty plate unit; for the winch system, the torque or speed control parameters are adapted and adjusted to ensure that the mooring rope release rhythm is precisely synchronized with the adjusted lifting and lowering motion of the plate turbine unit, maintaining stable rope tension. Simultaneously, the controller lowers the system's operating power threshold to prevent overload of normal components, ensuring the system continues wind energy conversion in degraded mode. Fault isolation prevents escalation, and parameter adjustments ensure uninterrupted core power generation functions, minimizing the impact of faults on power generation continuity and enhancing system fault tolerance.
[0061] Step 208: If it is a Level 3 fault, immediately execute the emergency shutdown procedure, including controlling all board units to turn to the vertical position, starting the winch emergency brake, and triggering the airbag depressurization.
[0062] In some embodiments, when the system determines a Level 3 fault, i.e., when it detects a serious situation such as airbag leakage, ambient wind speed exceeding the safety threshold of 1.5 times the design operating wind speed, or multi-point tethering rope tension soaring to a dangerous range, the controller immediately initiates an emergency shutdown procedure. First, a vertical state switching command is simultaneously issued to all plate units. The servo drives of each plate unit respond quickly, driving the plate unit to rotate around an axis parallel to the ground to a 90-degree vertical position. Then, the plate unit is firmly locked by the built-in electromagnetic brake or mechanical latch. At this point, the plate surface is parallel to the airflow direction, which can minimize air resistance and lift, and avoid the plate unit from being violently impacted by strong winds. At the same time, the controller triggers the mechanical emergency braking device of the winch. This device adopts a redundant design and is equipped with a thermal management system, which can instantly lock the rotating parts of the winch to prevent the mooring rope from being uncontrolled and prevent the plate unit from falling due to inertia or strong winds. In addition, the controller simultaneously opens the automatic pressure relief valve and redundant safety valve of the airbag, slowly releasing the gas in the airbag, gradually reducing the airbag's wind-exposed area and buoyancy, reducing the risk of the airbag becoming unstable or rolling in strong winds or leakage conditions, and creating conditions for the safe recovery of the system. The entire emergency shutdown procedure is rapid and coordinated, and can quickly cut off the source of risk in the event of a serious failure, minimizing the probability of equipment damage and ensuring the safety of the system and the surrounding environment.
