Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and more particularly to a polar wind power generation system. Background Technology

[0002] Under current technological conditions, there are three main energy acquisition solutions for polar regions with harsh climates, severe snowstorms, and insufficient logistical supplies: diesel power generation, photovoltaic power generation, and wind power generation.

[0003] Diesel power generation is currently the most widely used form of power generation in polar regions. However, diesel fuel poses significant risks in safe transportation, and its consumption and emissions are quite severe. Furthermore, it requires frequent maintenance and has a short period of safe and stable operation. Photovoltaic power generation's main advantage is its environmental friendliness, but its efficiency is limited, it occupies a huge area, and once the polar night begins, photovoltaic generators will essentially be shut down for extended periods.

[0004] In contrast, wind power effectively combines the advantages of both: polar regions have stable winds, wind turbines only need to be installed once to generate electricity continuously, and they are unaffected by polar nights, resulting in high power supply stability; furthermore, wind power generation produces no carbon emissions, making it environmentally friendly. However, although wind turbines are currently in use, their stability remains relatively poor, especially due to their larger size, which makes installation and use time-consuming, labor-intensive, and cumbersome, leading to high costs.

[0005] Therefore, there is an urgent need for a polar wind power generation system to solve the problems existing in the current technology. Summary of the Invention

[0035] The technical solution provided by the present invention will be described below with reference to the accompanying drawings and specific embodiments.

[0036] Combination Figures 1 to 6 As shown, this embodiment provides a polar wind power generation system, including a wind turbine generator assembly 10 and a control system 20. The wind turbine generator assembly 10 includes a mounting frame 11, a first blade group 12, a second blade group 13, and two sets of generator kits 14. The mounting frame 11 is fixedly installed. The first blade group 12 and the second blade group 13 are coaxially arranged, and the preset rotational wind speed of the first blade group 12 is less than the preset rotational wind speed of the second blade group 13. The two sets of generator kits 14 are circumferentially connected to the two ends of the first blade group 12 and the second blade group 13, respectively, and are both fixedly connected to the mounting frame 11 to achieve fixed assembly of the wind turbine generator assembly 10. The control system 20 is connected to the generator kits 14 to control the start and stop of the generator kits 14.

[0037] In practical use, for example, in light wind or low wind speed scenarios, the first blade group 12 can rotate to capture low wind speed energy and convert it into mechanical energy. Then, the mechanical energy is converted into electrical energy through the generator kit 14 to meet the basic power supply needs during low wind speed periods in polar scenarios. In medium to high wind speed scenarios, the first blade group 12 continuously rotates to generate electricity, while the second blade group 13 can start rotating synchronously under the action of wind energy. The two blade groups work together to capture wind energy and collect torque, which is then generated in parallel through the generator kit 14, thereby increasing the total power generation of the system. In strong wind or extremely high wind speed scenarios, the system can directly provide the required mechanical energy for the generator kit 14 through the second blade group 13 to compensate for the insufficient energy supply of the first blade group 12. This allows the polar wind power generation system to be used under different wind conditions, improving the power supply stability of the system in different environmental scenarios. Meanwhile, since a generator set 14 is set at each end of the second blade assembly 13, the power generation efficiency is higher. Moreover, the stable support points provided by the generator set 14 at both ends ensure that the second blade assembly 13 rotates more smoothly when blown by the wind, and the aerodynamic load is distributed more evenly. This avoids the phenomenon of shaft eccentric vibration caused by setting only one generator set 14, thus ensuring the stability and reliability of long-term operation. Furthermore, by having two generator sets 14 share the total load of the second blade assembly 13, the power rating of a single generator set 14 can be reduced from hundreds of kilowatts to tens of kilowatts, thereby greatly reducing the size of the equipment and manufacturing cost, and effectively filling the gap in the application of small wind turbine systems in polar regions.

[0038] In addition, the wind turbine assembly 10 is easy to install. After fixing the mounting bracket, the two sets of generator kits 14 are fixed to the mounting frame 11 to secure the generator kits 14. Then, the first blade assembly 12 and the second blade assembly 13 are assembled between the two sets of generator kits 14 and connected to them for transmission, thus completing the assembly of the wind turbine assembly 10. The number of parts used in this wind turbine assembly 10 is greatly reduced, thereby facilitating the maintenance and upkeep of the unit.

[0039] In some embodiments, reference Figure 2 , Figure 3As shown, the wind turbine generator assembly 10 is placed vertically; the mounting frame 11 specifically includes support columns 111 and crossbeams 112. The support columns 111 are evenly spaced around the outer periphery of the first blade assembly 12 and the second blade assembly 13. The bottom end of the support column 111 is embedded in the ground, and the bottom end of the support column 111 can be buried in the foundation pit 100 by backfilling with gravel soil to compact the foundation pit 100, improve the installation stability of the support column 111, and prevent the support column 111 from tilting; the crossbeams 112 are distributed at the bottom and top of the support columns 111. The crossbeams 112 at the bottom of the support column 111 and the crossbeams 112 at the top of the support column 111 are horizontally intersecting, and both ends of the crossbeams 112 are fixedly connected to the two support columns 111 arranged at an angle to each other. The middle section of the bottom crossbeam 112 can be fixedly connected to the generator assembly 14 below, and the middle section of the top crossbeam 112 can be fixedly connected to the generator assembly 14 above. The fixing methods include, but are not limited to, bolt connections, snap-fit ​​connections, and other detachable methods to facilitate disassembly and maintenance of the generator assembly 14. This design makes the mounting frame 11 relatively simple in construction, quick to form, and low in cost, while meeting the load-bearing stability requirements of most operating scenarios.

[0040] In this embodiment, reference Figure 3 As shown, specifically, a grid 15 is also provided on the top of the mounting frame 11. The grid 15 is laid on the top beam 112, which makes it convenient for workers to stand on the grid 15 to install, disassemble or repair the generator kit 14 located above, thus improving the safety of the operation process.

[0041] Those skilled in the art should understand that the material of the mounting frame 11 provided in this application is not limited, as long as its structural strength can meet the requirements of the actual use scenario. Preferably, in this embodiment, both the supporting column 111 and the crossbeam 112 are made of low-temperature resistant high-strength steel (such as Q355ND, Q460GJD, and other low-alloy high-strength weathering steel), so that the mounting frame 11 can be used normally under extreme environmental conditions such as polar gust wind speed ≥25m / s and polar temperature ≤-40℃.

[0042] In some embodiments, the first blade assembly 12 includes multiple willow-leaf shaped first blades. The willow-leaf structure of the first blades is adapted to the wind-catching requirements at low wind speeds. Compared with traditional wide-chord blades, it has stronger airflow adhesion at low wind speeds and is less prone to separation, thereby ensuring stable power generation during low-wind-speed periods in polar regions. In some preferred embodiments, the first blades are made of carbon fiber, which combines the advantages of lightweight, high strength, low-temperature resistance, and fatigue resistance, improving the stability and reliability of the first blades when used in polar regions. Preferably, three first blades are provided to ensure that the wind-catching efficiency meets actual needs.

[0043] In some embodiments, reference Figure 2 As shown, the second blade assembly 13 includes multiple C-shaped second blades 131, which are also made of carbon fiber to ensure structural strength and operational safety and stability. Furthermore, the C-shaped structure of the second blades 131 adapts to the wind capture requirements of medium to high wind speeds. The concave surface of the second blades 131 forms an airflow convergence channel, which can quickly gather airflow and generate strong aerodynamic lift when facing the wind, thus significantly improving the wind energy utilization coefficient and consequently increasing the total power generation. In some preferred embodiments, the second blade assembly 13 includes three second blades 131, which are equally spaced around the periphery of the first blade assembly 12.

[0044] In some embodiments, reference Figure 4 As shown, each generator assembly 14 includes a motor unit 141, a drive shaft 142, and a clutch mechanism (not shown in the figure). The motor unit 141 is axially positioned opposite each other at the upper and lower ends of the first blade group 12 and the second blade group 13. The fixed end of the motor unit 141 is fixedly connected to the crossbeam 112, and the input end of the motor unit 141 is drively connected to one end of the corresponding drive shaft 142. The other ends of the two drive shafts 142 can be integrally formed to form a synchronous shaft. The first blade group 12 is connected to the synchronous shaft, and a clutch mechanism is provided between the synchronous shaft and the second blade group 13. The clutch mechanism is used to control the engagement or disengagement of the second blade group 13 from the synchronous shaft.

[0045] With the above configuration, during low wind speed periods, the second blade assembly 13 can be disengaged from the synchronous shaft via the clutch mechanism, while only the first blade assembly 12 rotates with the synchronous shaft. The mechanical energy is converted into electrical energy through the individual motor units 141 at both ends. At this time, the synchronous shaft is driven only by the first blade assembly 12, and the individual motor units 141 do not need to overcome the rotational resistance of the second blade assembly 13, thus lowering the starting threshold and meeting the basic power supply requirements during low wind speed periods in polar regions. In a preferred embodiment, the clutch mechanism is connected to the control system 20, enabling the control system 20 to engage the clutch mechanism with the synchronous shaft when the target wind speed value is reached, forming a rigid transmission between the second blade assembly 13 and the synchronous shaft. This allows the first blade assembly 12 and the second blade assembly 13 to collaboratively capture wind energy and drive the synchronous shaft to rotate, while the individual motor units 141 at both ends generate electricity in parallel. This not only improves the overall power generation efficiency but also ensures that the total power generation meets actual electricity demand. Furthermore, it should be noted that the two end motor units 141 can operate independently or synchronously. When one end motor unit 141 fails, the other end electrode can continue to work, thereby avoiding unexpected shutdowns of the entire machine due to untimely polar maintenance.

[0046] In some instances, continue to refer to Figure 4 As shown, the wind turbine generator assembly 10 also includes blade connectors 16 and dampers 17. Each generator assembly 14 has three blade connectors 16 and three dampers 17. The blade connector 16 is used to connect one end of a second blade 131 to a clutch mechanism, and one damper 17 is provided at this position. Specifically, the two ends of the blade connector 16 are connected to the clutch mechanism and the second blade 131, respectively. The damper 17 is provided on the blade connector 16 and is used to buffer the pitch action of the second blade 131 to maintain the stability of its pitch angle.

[0047] The working relationship between the blade connector 16, the damper 17, and the second blade 131 is as follows: Under normal operating wind speed conditions, the second blade 131 generates stable aerodynamic lift through its aerodynamic shape. This lift is transmitted sequentially through the second blade 131, the blade connector 16, the clutch mechanism, and other components to the synchronous shaft, driving the synchronous shaft to rotate and generate electricity. At this time, the damper 17 is in a dynamic equilibrium state, suppressing minor vibrations of the corresponding part of the second blade 131 through a preset damping force to ensure constant power generation efficiency. When the wind speed exceeds the normal operating threshold, the second blade 131... When the aerodynamic load on the blade 131 increases significantly and exceeds the preset damping threshold of the damper 17, the second blade 131 deforms and pushes the blade connector 16 to rotate around its own axis, causing the damper 17 to be stressed. This allows the second blade 131 to reduce its wind-receiving area and reduce its rotational speed, thereby protecting the second blade 131. When the wind speed returns to normal, the damper 17 releases the stress and drives the blade connector 16 to rotate, thereby causing the second blade 131 to return to its normal wind-receiving area and continuously provide kinetic energy to the motor unit 141.

[0048] Through the above settings, dynamic adaptation to aerodynamic load changes can be achieved across the entire wind speed range. This ensures the stability of power generation efficiency under normal operating wind speeds and automatically protects the blades when the wind speed exceeds the threshold. Once the wind speed returns to normal, the system can quickly reset and continue supplying power, thereby significantly enhancing the safety of the wind turbine assembly 10. It is well-suited to the long-term operation requirements of complex polar wind farm environments.

[0049] In some embodiments, the wind turbine generator assembly 10 further includes an anemometer 18, which is communicatively connected to the control system 20. This allows the control system 20 to send a control command to the clutch mechanism to engage the synchronous shaft with the second blade assembly 13 based on the actual wind speed. This enables the second blade assembly 13 to automatically engage or disengage with the synchronous shaft based on the wind speed in the external environment, thereby improving the wind turbine generator assembly 10's response to environmental wind speed and making the power supply stability of the system higher.

[0050] In some embodiments, the wind turbine generator assembly 10 further includes a first temperature detector 19, which is communicatively connected to the control system 20. The control system 20 can send control commands to the generator assembly 14 based on the detection results. Specifically, the first temperature detector 19 continuously monitors the ambient temperature of the covered area and sends the monitored ambient temperature signal to the control system 20. After receiving the temperature signal, the control system 20 makes a judgment. If it determines that the current temperature signal is lower than the normal threshold, it can send a power compensation control command to the individual generator 141 to increase the power generation efficiency of the individual generator 141 and increase the output power of the individual generator 141 to offset the energy loss in the low-temperature environment and ensure the stability of the power supply. If it determines that the current temperature signal is higher than the normal threshold, it can send a power limiting command to the individual generator 141 to reduce the output power of the individual generator 141, thereby suppressing the temperature rise of the individual generator 141 and avoiding damage to the individual generator 141 caused by high temperature, thus effectively ensuring the safe and reliable use of the individual generator 141.

[0051] In some embodiments, reference Figure 5 As shown, the control system 20 includes a storage compartment 21 and a temperature control component 22, wherein the temperature control component 22 is installed inside the storage compartment 21. The temperature control component 22 includes a second temperature sensor, a temperature regulator, and a temperature regulation control unit. The second temperature sensor is used to detect the indoor temperature of the storage compartment 21 and is communicatively connected to the temperature regulation control unit, which is electrically connected to the temperature regulator. Through the above configuration, the temperature inside the storage compartment 21 can be maintained within a normal range, preventing excessively high or low temperatures from affecting the normal operation of other components.

[0052] In some specific embodiments, the temperature regulating components include an exhaust fan and a heater. The exhaust fan is used for ventilation, cooling, dehumidification and air exchange in high temperature or high humidity scenarios inside the storage compartment 21, while the heater is used for heating and heat preservation in low temperature scenarios. Under the coordinated control of the temperature regulating control unit, the two components achieve precise and stable indoor temperature in the storage compartment 21 within a safe range, thereby adapting to the operational needs of the components inside the storage compartment 21 in extreme polar environments.

[0053] In some embodiments, the control system 20 further includes a wind power generation control component 23, which includes a grid intelligent control unit, a wind power charging control cabinet, and a DC combiner cabinet. The wind power charging control cabinet houses a main wind power charger and a backup wind power charger, which are electrically connected to the wind turbine generator assembly 10 to supply power to the main and backup wind power chargers via the wind turbine generator assembly 10. At least two wind turbine generators are provided; for example, in this embodiment, two sets of wind turbine generator assemblies 10 are provided, each electrically connected to the main and backup wind power chargers respectively. The two sets of wind turbine generator assemblies 10 are used simultaneously, thereby increasing the system's power generation capacity and improving equipment utilization. The DC combiner cabinet includes a cabinet body, and an inverter and combiner unit located inside the cabinet body. The cabinet body is equipped with a main interface, a backup interface, and multiple AC output interfaces. The main interface is connected to the main wind power charger, and the backup interface is used to connect to the backup wind power charger. The combiner unit is electrically connected to two wind turbine generator assemblies 10, thereby realizing the return current of the wind turbine generator assemblies 10 and the power distribution to the backup power supply, ensuring the balanced power supply of the system. The input terminal of the inverter is connected to the combiner unit, and the output terminal of the inverter is connected to multiple AC output interfaces, enabling the inverter to directly provide 12V, 24V, 220V, and 380V multi-voltage power supply guarantee capability. The grid intelligent control unit is electrically connected to the wind turbine generator assemblies 10, thereby realizing the grid power supply of multiple wind turbine generator assemblies 10.

[0054] In some embodiments, the control system 20 further includes an energy storage component, which includes an energy storage unit and an energy storage control unit 242. The energy storage unit is electrically connected to the wind turbine generator assembly 10, and the energy storage control unit 242 is electrically connected to the energy storage unit. In some specific embodiments, the energy storage unit includes two sets of low-temperature resistant lithium battery packs 2411 (each pack can store 100 kWh, totaling 200 kWh). Each lithium battery pack 2411 consists of multiple independent battery cells, which absorb electrical energy transmitted from the wind turbine generator assembly 10. The energy storage control unit 242 is primarily responsible for performance monitoring, energy distribution management, charge / discharge safety management, and grid connection management of the energy storage lithium battery pack 2411. Regarding performance monitoring, it can monitor the total voltage and current of each energy storage lithium battery pack 2411, as well as the voltage, temperature, and SOC (state of charge) and SOH (state of health) of individual battery cells. It can switch to another energy storage lithium battery pack 2411 for connection and use at any time based on the status of the battery cells, thereby ensuring the safety and stability of the charge / discharge process. Regarding energy distribution management, when the wind turbine generator assembly 10 generates sufficient power (e.g., during medium-to-high wind speed periods), the energy storage control unit 242 can be used to activate both energy storage lithium battery packs. Battery pack 2411 prioritizes equalization charging of energy storage lithium battery pack 2411. When the wind turbine generator assembly 10 generates insufficient power or shuts down, the energy storage control unit 242 can allocate discharge power according to load demand, prioritizing power supply from the energy storage unit to ensure power supply stability. Regarding charge and discharge safety management, when the temperature of a single battery cell is detected to be lower than the safe value, the heating element inside the energy storage lithium battery pack 2411 can be activated to preheat the battery temperature before starting charge and discharge, avoiding capacity decay caused by low-temperature charge and discharge. Regarding grid connection management, the energy storage unit can work in tandem with the wind turbine generator assembly 10 to supply power, smoothing out the fluctuations in wind power generation and making the power supply more stable.

[0055] In some embodiments, the control system 20 further includes a fire extinguishing assembly 25 disposed within the storage compartment 21. The fire extinguishing assembly 25 includes a fire detector, a fire extinguishing element, and a fire extinguishing control unit. The fire detector monitors fire signals (such as temperature, smoke, and gas concentration) within the storage compartment 21 in real time and communicates with the fire extinguishing control unit. The fire extinguishing control unit is electrically connected to the fire extinguishing element, forming a "monitoring-judgment-triggering" fire extinguishing control link. The fire detector can integrate a temperature sensor, an aversion sensor, and a combustible gas sensor into one unit, resulting in higher monitoring accuracy. The fire extinguishing element can be one or more of an aerosol fire extinguishing device, a dry powder fire extinguishing device, and a carbon dioxide fire extinguishing device, allowing for the selection of the most suitable element based on the actual situation, thus improving fire extinguishing efficiency. After confirming a fire, the fire extinguishing control unit can immediately activate the fire extinguishing element to extinguish the fire in the affected area, eliminating the need for external control and reducing the supervisory burden on personnel.

[0056] In some embodiments, the control system 20 further includes an emergency repair platform 26, which includes a workbench 261 and a spare parts toolbox 262, enabling operators to obtain the necessary repair tools from the spare parts toolbox 262 and perform component repairs on the workbench 261, thereby meeting the needs of on-site inspection and repair.

[0057] It should be further noted that, in some embodiments, the polar wind power generation system also includes an auxiliary power supply system 27, which is electrically connected to the control system 20 to determine whether to supply power to the control system 20 based on its operating status. In some specific embodiments, refer to... Figure 6 As shown, the auxiliary power supply system 27 includes a 600W low-temperature resistant, high-performance solar power generation system 271. The solar power generation system 271 includes multiple photovoltaic panels 2711 installed on the top cover of the storage compartment 21. These photovoltaic panels 2711 convert solar energy into the required electrical energy. During normal use, it can monitor the second temperature detector, temperature regulation control unit, temperature regulator, smart grid control unit, energy storage control unit 242, and fire suppression control unit, and provide emergency power based on the monitoring results. This ensures that each system can operate normally in the event of power outages or other special circumstances, thus enhancing the safety and reliability of the polar wind power generation system.
