Description

Technical Field

[0001] The present application relates to the field of wind power generation technology, and in particular to a wind turbine blade deicing method, a wind turbine generator set, and a program product. Background Art

[0002] Wind power, a key renewable clean energy technology, has seen rapid global expansion in recent years. Early technology development focused on optimizing blade aerodynamic efficiency and improving the energy transfer efficiency of transmission systems. With the development of the wind power industry, wind farms have gradually expanded to colder, higher-altitude regions with excellent wind resources but harsher environmental conditions.

[0003] In cold and humid environments, wind turbine blades face severe icing challenges. Ice accumulation on the blade surface significantly alters its aerodynamic profile, leading not only to deterioration in aerodynamic performance and reduced power generation efficiency, but also to disruption of the rotor system's dynamic balance, causing abnormal vibration, fatigue damage, and even structural failure. This can trigger unplanned downtime, directly impacting wind farm operational stability and economic returns.

[0004] In response to this, the industry has explored and applied a variety of blade de-icing or anti-icing technologies, such as manual de-icing that relies on maintenance personnel using professional tools to manually scrape or knock off the ice layer, hot air de-icing by generating hot air through the HVAC system inside the wind turbine or by introducing an external heat source, and electric heating de-icing by setting electric heating components inside or in specific areas of the surface of the wind turbine blades.

[0005] However, the above-mentioned traditional single deicing methods have problems such as high safety risks, high energy consumption, and low efficiency, and the deicing effect is relatively general, which makes it difficult to meet the requirements of safe, energy-saving, efficient and reliable deicing.

[0006] Therefore, a new de-icing method for wind turbine blades is urgently needed to solve the problems of high safety risks, high energy consumption, low efficiency, and relatively general de-icing effect of traditional single de-icing methods.

In addition, a graded response based on icing monitoring data and a feedback mechanism that analyzes the later icing degree and de-icing effect after a first preset time interval enables dynamic optimization of de-icing operations, avoids excessive use of high-energy-consuming components, reduces unnecessary energy consumption, ensures thorough de-icing, and improves reliability. At the same time, the entire de-icing process is executed automatically, reducing the need for manual intervention and lowering the safety risks for maintenance personnel at high altitudes or in cold environments.

[0080] Overall, the technical solution of this application effectively solves the problems of high energy consumption, low efficiency and high safety risks of traditional methods through multi-technology collaboration and intelligent control, meets the needs of safe, energy-saving, efficient and reliable de-icing, and achieves an improvement in the overall de-icing effect.

[0081] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device or computing terminal capable of implementing the above functions. The following uses a computing terminal as an example to illustrate this embodiment and the following embodiments.

[0082] Based on this, the embodiment of the present application provides a method for deicing wind turbine blades, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the wind turbine blade de-icing method of the present application.

[0083] In this embodiment, the wind turbine blade deicing method is applied to a wind turbine generator set, wherein the wind turbine generator set includes a tower and multiple blade structures, wherein the surfaces of the blade structures are coated with a photothermal material coating, the blade structures are provided with a mechanical vibration component, and the tower is provided with a focusing reflective component;

[0084] The wind turbine blade deicing method includes steps S10 to S60:

[0085] Step S10, acquiring environmental data; wherein the environmental data at least includes icing monitoring data of the blade structure;

[0086] It should be noted that environmental data can include a variety of environmental data, such as blade structure icing monitoring data, wind field data, lighting conditions data, meteorological data, and so on. By acquiring and analyzing environmental data, a series of relevant information such as the icing status of the blade structure, the cause of icing, and the difficulty of de-icing can be obtained. Environmental data can be collected and acquired using relevant sensors, such as temperature sensors, anemometers, and light sensors.

[0087] Step S20, analyzing and obtaining an initial icing degree based on the icing monitoring data;

[0088] Step S30, when the initial icing degree reaches a first level and is lower than a second level, activating the light-concentrating reflective assembly, operating the light-concentrating reflective assembly to focus light to form a focused light beam, and reflecting the focused light beam toward the photothermal material coating;

[0089] The first level of severity can be pre-stored in the memory of the computing terminal. A technician can pre-store numerical information corresponding to the first level of severity in the memory of the computing terminal and mark it as the first level of severity. Of course, the first level of severity can also be uploaded and updated to the memory of the computing terminal through various methods such as burning, communication transmission, etc., such as transmission via a USB flash drive, 4G network, Bluetooth connection, etc., which will not be detailed here.

[0090] It should be noted that the focusing and reflecting assembly can communicate with the computing terminal via a communication connection method such as a 4G network, WiFi, or Bluetooth connection, thereby enabling the computing terminal to control the focusing and reflecting assembly. The focusing and reflecting assembly can include a series of lens assemblies, such as lenses and reflectors, to achieve focusing and reflection effects. As an optional embodiment, the reflectors of the focusing and reflecting assembly can be flexible reflective panels, so that the curvature of the flexible reflective panel can be adjusted by the computing terminal controlling the transmission system to achieve fine-grained adjustment of light reflection.

[0091] Step S40: When the initial icing degree reaches a second level, the focusing and reflecting assembly and the mechanical vibration assembly are activated, the focusing and reflecting assembly is operated to focus light to form a focused light beam, and the focused light beam is reflected toward the photothermal material coating, and the mechanical vibration assembly is operated to vibrate the blade structure;

[0092] Similarly, the second level can be pre-stored in the memory of the computing terminal. A technician can pre-store numerical information corresponding to the second level in the memory of the computing terminal and mark it as the first level. Of course, the second level can also be uploaded and updated to the memory of the computing terminal through various methods such as burning, communication transmission, etc., such as transmission via a USB flash drive, 4G network, Bluetooth connection, etc., which will not be detailed here.

[0093] In addition, it should be noted that the mechanical vibration component can be a component such as a vibration generator including a vibrator. The mechanical vibration component can be communicatively connected or electrically connected to the computing terminal, thereby allowing the computing terminal to control the mechanical vibration component to activate the mechanical vibration component to generate vibration.

[0094] Step S50, after a first preset time interval, analyzing and obtaining a later icing degree based on the real-time icing monitoring data;

[0095] The first preset time interval can be set by a technician based on their own experience and actual needs and pre-stored in the memory of the computing terminal. For example, the first preset time interval can be set to 5 minutes, so that the real-time icing monitoring data is monitored with a 5-minute monitoring cycle and analyzed to obtain the later icing degree.

[0096] Step S60: analyzing and obtaining a deicing effect based on the late icing degree and the initial icing degree, and executing or terminating a deicing operation based on different deicing effects.

[0097] This embodiment provides a wind turbine blade deicing method. By combining a photothermal coating, a concentrating reflective assembly, a mechanical vibration assembly, and a graded response mechanism based on icing severity, this method achieves safe, energy-efficient, efficient, and reliable deicing of wind turbine blades. Specifically, by acquiring environmental data and analyzing icing monitoring data within the environmental data, an initial icing severity is determined. This initial icing severity is then compared with pre-stored icing severity levels to determine the corresponding deicing method. Afterwards, when the initial degree of icing is lower than the first level, it indicates that the icing situation is relatively small, so the ice can be melted by relying solely on the photothermal material coating coated on the blade structure to absorb the heat converted from natural sunlight; when the initial degree of icing reaches the first level and is lower than the second level, it indicates that the blade structure is relatively iced. In this state, only the focusing and reflecting component is activated to focus the light to form a light beam and reflect it to the coating. The photothermal material efficiently absorbs light energy and converts it into heat energy to directly and specifically melt the ice layer, avoiding the energy waste of heating the entire blade in traditional electric heating or hot air deicing, thereby significantly reducing energy consumption; when the initial degree of icing reaches the second level, it indicates that the icing situation is serious. In this state, the focusing and reflecting component and the mechanical vibration component are synchronously activated to enhance the photothermal melting effect, and the vibration deicing generated by the mechanical vibration component is manipulated to form a synergistic mechanism of photothermal softening and mechanical vibration crushing deicing, significantly improving the deicing efficiency, achieving a reliable and efficient deicing effect, and overcoming the low efficiency of a single deicing method. In addition, a graded response based on icing monitoring data and a feedback mechanism that analyzes the later icing degree and de-icing effect after a first preset time interval enables dynamic optimization of de-icing operations, avoids excessive use of high-energy-consuming components, reduces unnecessary energy consumption, ensures thorough de-icing, and improves reliability. At the same time, the entire de-icing process is executed automatically, reducing the need for manual intervention and lowering the safety risks for maintenance personnel at high altitudes or in cold environments.

[0098] Overall, the technical solution of this application effectively solves the problems of high energy consumption, low efficiency and high safety risks of traditional methods through multi-technology collaboration and intelligent control, meets the needs of safe, energy-saving, efficient and reliable de-icing, and achieves an improvement in the overall de-icing effect.

[0099] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction and will not be repeated hereafter. On this basis, the environmental data at least further includes lighting condition data;

[0100] Please refer to Figure 2 , step S30 further includes steps S31 to S33:

[0101] Step S31, when the initial icing degree reaches a first level and is lower than a second level, determining a lighting condition level based on the lighting condition data;

[0102] Step S32: if the illumination level reaches the light intensity threshold, activating the light-concentrating reflective component, manipulating the light-concentrating reflective component to focus the light to form a focused light beam, and reflecting the focused light beam toward the photothermal material coating;

[0103] Among them, the light intensity threshold can be set according to factors such as the lighting conditions in different regions and the photothermal conversion efficiency of different photothermal materials. The light intensity threshold can be pre-stored in the memory of the computing terminal, or it can be transmitted and updated to the memory of the computing terminal through 4G, 5G, WiFi, Bluetooth and other communication methods, which will not be repeated here.

[0104] Step S33: If the illumination level does not reach the light intensity threshold, the mechanical vibration component is activated and controlled to vibrate the blade structure.

[0105] Similarly, the second light intensity threshold can be set according to factors such as the lighting conditions in different regions and the photothermal conversion efficiency of different photothermal materials. The second light intensity threshold can be pre-stored in the memory of the computing terminal, or it can be transmitted and updated to the memory of the computing terminal through 4G, 5G, WiFi, Bluetooth and other communication methods, which will not be repeated here.

[0106] In the second embodiment of the present application, this embodiment further optimizes the energy efficiency and reliability of de-icing operations by incorporating lighting condition data into environmental data and designing a hierarchical response logic. Specifically, when the initial ice formation level is at the first level, a new step is added to determine the light level based on the lighting condition data. If the light condition level reaches the light intensity threshold, the focusing reflector assembly is activated to reflect the light beam to the photothermal material coating, directly and efficiently melting the ice using light energy, significantly reducing energy consumption. If the light condition level does not reach the light intensity threshold, indicating that the light intensity is insufficient in the given scenario, making it difficult to achieve de-icing through photothermal conversion, the mechanical vibration assembly is automatically activated to vibrate the blades to de-ice. This effectively addresses the core issue of the sudden drop in photothermal de-icing efficiency in low-light environments such as cloudy days and nighttime. By dynamically selecting the appropriate de-icing mode, this embodiment avoids the energy waste caused by forcing inefficient photothermal de-icing when light is insufficient, while ensuring that de-icing operations are always reliable. Furthermore, when the light condition level is between the first and second levels, the mechanical vibration method serves as a backup for insufficient light and is only activated when necessary, thereby reducing the overall energy consumption of the de-icing solution. Overall, the design achieves an upgrade in environmental adaptability through the dual guarantees of light and heat priority and vibration emergency response, while maintaining the reliability of the de-icing effect and extending the energy-saving advantages to all-weather scenarios.

[0107] Based on the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the second embodiment can be referred to the above introduction and will not be described in detail. On this basis, the blade structure is further provided with a heating component;

[0108] Please refer to Figure 3 , step S40 may include steps S41 to S43:

[0109] Step S41, when the initial icing degree reaches a second degree level, determining the lighting condition level based on the lighting condition data;

[0110] Step S42: If the light condition level reaches the light intensity threshold, the focusing and reflecting assembly and the mechanical vibration assembly are activated, the focusing and reflecting assembly is operated to focus the light to form a focused light beam, and the focused light beam is reflected toward the photothermal material coating, and the mechanical vibration assembly is operated to vibrate the blade structure;

[0111] Step S43: If the illumination level does not reach the light intensity threshold, the mechanical vibration component and the heating component are started, the mechanical vibration component is controlled to vibrate the blade structure, and the heating component is controlled to heat the blade structure.

[0112] It should be noted that the heating assembly may include heating devices such as electric heating devices and thermal radiation heating devices, which can heat the blade structure through at least one of heat transfer, thermal radiation, and thermal convection, thereby achieving the effect of melting ice.

[0113] In the third embodiment of the present application, this embodiment significantly improves the reliability and adaptability of de-icing in heavy icing scenarios by introducing a collaborative control strategy for the heating component in heavy icing scenarios where the initial icing level reaches the second level. Specifically, when the initial icing level reaches the second level, it indicates that the blade structure is heavily frozen. In this state, a dual-mode switching mechanism based on light condition data is added: if the light condition level reaches the light intensity threshold, the collaborative effect of the focusing reflective component and the mechanical vibration component in the basic scheme is maintained, and the ice layer structure is softened by light and heat melting and supplemented by vibration crushing and peeling; if the light condition level reaches the light intensity threshold, it automatically switches to a combined mode of starting the heating component and the mechanical vibration component, and the ice layer is softened by the targeted addition of heat energy by the heating component, and the ice layer is crushed and peeled off by mechanical vibration. This solution creatively solves the risk of de-icing failure in scenarios with heavy icing and low light levels. By using the heating component as a solar thermal alternative, it directly compensates for the lack of ambient light energy and ensures the reliability of the heat supply. The mechanical vibration is always running to enhance the efficiency of ice stripping, creating a dual de-icing effect of thermal softening and mechanical crushing. In addition, the heating component is only activated when there is heavy icing and insufficient light. Compared with traditional full-process electric heating solutions, it greatly reduces the heating time and energy consumption, while avoiding the limitation that a single vibration method cannot break the ice when the ice layer is too thick. Overall, this synergistic strategy dynamically matches the energy type and de-icing intensity to achieve stable de-icing effects under extreme working conditions while maintaining the system's energy-saving advantages.

[0114] In one feasible embodiment, the photothermal material coating is a composite coating of a photothermal polymer and carbon nanotubes, and the photothermal polymer includes at least one of polypyrrole, polyaniline, and polydopamine; the heating component includes an electric heating device and a microwave generator;

[0115] Step S43 may include steps S431 to S433:

[0116] Step S431, starting the mechanical vibration component and operating the mechanical vibration component to vibrate the blade structure;

[0117] Step S432, starting the electric heating device to heat the blade structure using the electric heating device;

[0118] Step S433: start the microwave generator and control the microwave generator to emit microwaves toward the photothermal material coating, so that the carbon nanotubes in the photothermal material coating absorb the microwaves and heat the blade structure.

[0119] It should be noted that the photothermal coating is a composite coating of photothermal polymers and carbon nanotubes. The photothermal polymer includes at least one of polypyrrole, polyaniline, and polydopamine. These photothermal polymers have high light absorption rates and high photothermal conversion efficiencies, making them suitable for use as photothermal coatings. They absorb light and heat the blade structure to melt ice. The photothermal coating also contains carbon nanotubes, which have excellent microwave absorption and heat conversion capabilities. After absorbing microwave radiation, they can efficiently convert it into heat, heating the blade structure.

[0120] In this embodiment, by optimizing the composition of the photothermal material coating and synergizing the dual heat sources of the heating component, de-icing efficiency and energy utilization in heavy icing scenarios are significantly improved. Specifically, by using a photothermal polymer composite coating containing photothermal polymer and carbon nanotubes, the photothermal polymer can achieve photothermal conversion within the visible light band, while the carbon nanotubes can absorb microwaves and efficiently convert them into heat energy. By activating the mechanical vibration component, the electric heating device, and the microwave generator when the light condition level does not reach the light intensity threshold, the de-icing method utilizes mechanical vibration, electric heating, and microwave heating to achieve a composite synergistic de-icing effect: mechanical vibration removes the attached ice layer on the blade structure, the electric heating device heats the entire blade structure, and the carbon nanotubes absorb microwaves to heat the surface of the blade structure, further improving de-icing efficiency.

[0121] The photothermal material coating in this embodiment creatively combines photothermal polymers and carbon nanotubes to form a composite coating. The photothermal polymer maintains the photothermal conversion capability of the visible light band when there is sufficient light, and utilizes the microwave heating characteristics of the carbon nanotubes to enable the same coating to adapt to electromagnetic radiation of two types of bands and achieve a heating effect.

[0122] Based on any of the above embodiments of the present application, in the fourth embodiment of the present application, the same or similar contents as any of the above embodiments can be referred to the above introduction and will not be repeated hereafter. On this basis, the environmental data also includes wind field data;

[0123] Please refer to Figure 4 , step S60 may include steps S61 to S63:

[0124] Step S61, if the late icing level is lower than the first level, then end the deicing operation;

[0125] It should be noted that if the degree of icing in the later stage is lower than the first level, it indicates that there is less ice on the blade structure and it no longer affects the operation of the blade structure, or the remaining deicing effect can be achieved by absorbing visible light through the photothermal material coating. Therefore, the deicing operation can be terminated in this state.

[0126] Step S62: If the later freezing level reaches the first freezing level and the later freezing level is lower than the initial freezing level, then the deicing operation is maintained until the later freezing level is lower than the first freezing level.

[0127] It should be noted that if the later icing degree reaches the first level and the later icing degree is lower than the initial icing degree, it indicates that there is still a lot of ice on the blade structure, but the icing situation has improved compared to the initial icing degree, which means that the current deicing operation is effective, so maintaining the current deicing operation can effectively remove ice.

[0128] Step S63: If the later icing degree is higher than or equal to the initial icing degree, adjusting the pitch angle of the blade structure and the yaw angle of the wind turbine generator set based on the wind field data so that the blade surface of the blade structure is parallel to the incoming wind direction in the wind field data.

[0129] It should be noted that if the later degree of icing is higher than or equal to the initial degree of icing, it indicates that the current de-icing operation is insufficient to effectively de-ice, and the blade structure is still continuously icing. Therefore, the pitch angle of the blade structure and the yaw angle of the wind turbine can be adjusted based on the wind field data to make the blade surface of the blade structure parallel to the incoming wind direction in the wind field data, thereby reducing the surface area of ​​the blade structure affected by cold currents and snow accumulation, reducing the impact of harsh environments on the blade structure, and reducing the icing rate of the blade structure, thereby reducing the required de-icing efficiency from the source.

[0130] In the fourth embodiment of the present application, this embodiment realizes the ability to actively intervene in continuous icing conditions by introducing a closed-loop control strategy based on wind farm data. Specifically, after analyzing the difference between the late icing degree and the initial icing degree, three types of graded response logic are formed: when the late icing degree is lower than the first level, de-icing is terminated directly to avoid energy waste; when the late icing degree is reduced but not completely cleared, the de-icing operation is maintained until effective de-icing is completed; when the late icing degree is higher than or equal to the initial icing degree, the blade pitch angle and the unit yaw angle are dynamically adjusted based on the wind farm data so that the windward surface of the blade is parallel to the incoming wind direction, thereby fundamentally reducing the ice accumulation area on the surface of the blade structure, significantly reducing the accumulation of supercooled water droplets on the surface of the blade structure, and then reducing the icing rate of the blade structure, and reducing the required de-icing efficiency from the source.

[0131] In one feasible implementation, the wind turbine generator set further includes a hub and a nacelle; step S63 may include steps S631 to S633:

[0132] Step S631: If the late icing degree is higher than or equal to the initial icing degree, adjusting the reflection direction of the focusing reflective assembly so that the focused light beam is reflected toward the hub and the nacelle;

[0133] Step S633: Based on the wind field data, adjust the pitch angle of the blade structure and the yaw angle of the wind turbine generator set so that the blade surface of the blade structure is parallel to the incoming wind direction.

[0134] In this embodiment, the dynamic steering control of the concentrating and reflecting assembly, in conjunction with wind field regulation, significantly enhances system protection capabilities under persistent icing conditions. Specifically, when the late icing level is higher than or equal to the initial icing level, dual control is implemented: the reflection direction of the concentrating and reflecting assembly is adjusted to redirect the focused beam toward the hub and nacelle surfaces, allowing the photothermal coating to rapidly melt ice from critical areas, preventing hub bearing seizure and nacelle equipment failure. Simultaneously, the blade pitch angle and turbine yaw angle are adjusted based on wind field data to align the windward surface of the blades with the incoming wind direction, significantly reducing the collision area of ​​supercooled water droplets on the blade leading edge. This solution ensures smooth blade pitch control and wind turbine yaw operations by reflecting the focused beam toward the hub and nacelle, effectively preventing hub bearing seizure and nacelle equipment failure. After the blade pitch control and wind turbine yaw operations are completed, the reflection direction of the concentrating and reflecting assembly is adjusted again to redirect the focused beam toward the photothermal coating, continuing to de-ice the blade surface.

[0135] Furthermore, in a feasible embodiment, the hub and the nacelle are both provided with heating components; after step S631, the wind turbine blade deicing method may further include step S632:

[0136] Step S632: Start the heating components located at the wheel hub and the nacelle, so that the heating components heat the wheel hub and the nacelle.

[0137] In this embodiment, by additionally utilizing heating components located at the hub and the nacelle to heat the hub and the nacelle, ice covering the hub and the nacelle can also be quickly melted, thereby preventing the ice covering the hub and the nacelle from affecting pitch and yaw operations.

[0138] Based on the first embodiment of the present application, in the fifth embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above introduction and will not be repeated hereafter. On this basis, the environmental data also includes wind field data;

[0139] Please refer to Figure 5 After step S60, the wind turbine blade deicing method may further include step S70:

[0140] Step S70: Acquire meteorological data for a second preset time interval in the future, and adjust the benchmarks of the first level and the second level based on the meteorological data.

[0141] In the fifth embodiment of the present application, this embodiment significantly improves the environmental adaptability and energy utilization of the de-icing system through a dynamic calibration mechanism of the icing threshold driven by meteorological prediction. Specifically, new meteorological data (such as temperature, humidity, wind speed forecast, etc.) for the second preset time interval in the future are newly acquired, and the judgment criteria of the first degree level and the second degree level are dynamically adjusted based on meteorological trends. For example, when a cold wave warning is detected, the judgment criteria value of the icing degree level is automatically lowered, so that the system starts the de-icing operation in advance before the ice layer becomes thicker, avoiding the delayed de-icing response due to sudden low temperatures; and when the weather is predicted to warm up, the judgment criteria value of the icing degree level is appropriately increased to prevent excessive de-icing operations from causing energy waste. This embodiment introduces meteorological prediction data into the icing prevention and control decision chain, and constructs a preventive de-icing mechanism by adaptively adjusting the level threshold, thereby ensuring the timeliness of de-icing while avoiding ineffective de-icing operations.
