Description

Technical Field

[0001] The invention relates to the field of renewable energy, in particular to a floating wind power system. Background Art

[0002] With the continuous growth of global energy demand and the improvement of environmental protection awareness, renewable energy technology, especially wind power generation technology, has developed rapidly in the past few decades. Onshore wind power generation technology is quite mature, but due to factors such as available land resources and environmental impact, offshore wind power generation has gradually become the focus of industry attention in recent years.

[0003] Traditional offshore wind power generation mainly uses fixed foundation structures, such as monopile foundations, gravity foundations, etc. These structures perform well in shallow waters, but as development moves toward deep waters, fixed structures face challenges such as high technical difficulty and high costs. To overcome these problems, floating wind power generation systems came into being.

[0004] At present, there are several main types of floating wind power generation systems: vertical floating, tension leg platform and semi-submersible. The most typical design uses 3-4 pontoon support structures, which are characterized by a small span between pontoons, usually only 1 / 5 to 1 / 6 of the height of the wind tower. This design mainly relies on cable fixation to achieve stability. The pontoon only solves the buoyancy problem but fails to solve the structural stability problem at the same time. Under strong wind conditions, due to the small span and limited support range, it is easy to produce excessive tilt or even overturning risks. In addition, the existing floating wind turbine platform can usually only support a single wind turbine, and the capacity of a single unit is limited, making it difficult to achieve large-scale power generation; under severe water conditions, the wind and wave resistance of a single pontoon structure is limited, affecting power generation efficiency and equipment safety. Or the transportation, installation and maintenance of large single floating platforms are difficult to construct and maintain, and the existing cable fixing method is difficult to effectively prevent the system from overturning under extreme conditions.

[0005] Therefore, there is an urgent need for a new type of floating wind power generation system that can simultaneously solve problems such as multi-machine layout, stability, economy and system integration, so as to promote the development of offshore wind power to deeper waters and improve power generation efficiency and economic benefits. Summary of the invention

[0006] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a floating wind power system that simultaneously solves the problems of multi-machine layout, stability, economy and system integration, so as to achieve large-scale, high-efficiency and low-cost water wind power generation.

[0007] The technical solution of the present invention is:

[0008] A floating wind power system comprises at least three wind turbines connected together by buoys to form a wind power generation system.

[0009] Preferably, a plurality of buoys are connected end to end to form a high-strength floating platform with a triangular structure or a rectangular structure.

[0010] Preferably, a stabilizing structure is provided between at least two buoys.

[0011] Preferably, the stabilizing structure comprises at least one truss structure.

[0012] Preferably, tower bases are provided on at least two connected buoys.

[0013] Preferably, a plurality of fixed traction devices are provided on the high-strength floating platform.

[0014] Preferably, the high-strength buoy platform is also provided with a driving device and a power supply device.

[0015] Preferably, the wind turbine generator set comprises a tall wind turbine and a short wind turbine, and the tall wind turbine and the short wind turbine are arranged diagonally on the floating platform.

[0016] Preferably, the tall wind turbine comprises a tower column and an auxiliary support system, and the auxiliary support system comprises an auxiliary long support and an auxiliary cross bar.

[0017] Preferably, the high-strength floating platform is provided with a tripod structure, which includes a large tripod and a small tripod, the large tripod is used to support a tall wind turbine, and the small tripod is used to support a short wind turbine.

[0018] Beneficial effects of the present invention:

[0019] (1) By setting at least three wind turbines and a high-strength floating platform to form a wind power generation system, where the span of the high-strength floating platform is greater than or equal to the height of the wind power tower, a safe and stable layout of a large-scale deep-water wind power system is achieved. Compared with the traditional single-machine floating wind power system and its span design of only 1 / 5-1 / 6 of the tower height, the present invention not only solves the problem of limited single-machine capacity, but also significantly improves the system's anti-overturning ability. Its large span design enables the wind power generation system to tilt at most a limited angle under extreme conditions without overturning, fundamentally improving the system safety.

[0020] (2) By innovatively adopting the core plate box structure of the buoy design, an integrated solution of structural support and buoyancy is achieved. Compared with the traditional buoy design that only solves the buoyancy problem, the buoy of the present invention not only serves as a support structure but also provides buoyancy, significantly improving the overall performance of the system. At the same time, the modular design not only simplifies the production process and reduces the amount of labor, but also facilitates transportation and on-site assembly, greatly reducing the difficulty of construction and maintenance costs.

[0021] (3) Compared with the traditional design that relies on cable fixation, the present invention provides the main stable support through the structural characteristics of the large-span floating platform, and the cables only serve as auxiliary fixing devices, which significantly improves the stability and reliability of the system under severe sea conditions and provides a safer and more efficient solution for deep-water wind power development.

[0022] Through the high and low staggered wind turbine layout scheme, combined with the differentiated design of large and small tripods, the three-dimensional utilization of wind energy is achieved, which not only effectively reduces the wake interference between wind turbines and improves the overall power generation efficiency of the system, but also optimizes the distribution of platform carrying capacity and makes the structure more reasonable.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figure 1-5 As shown, a floating wind power system includes three wind turbines 1 and a high-strength floating platform 2 to form a wind power generation system; the high-strength floating platform 2 includes a plurality of connected buoys.

[0039] Specifically, the high-strength floating platform 2 is an equilateral triangle structure, each side of the triangle structure is connected by three pontoons 3 made of core plates 11, and two adjacent pontoons 3 are fastened together by flanges and bolts. Each pontoon 3 is composed of three core plates 11.

[0040] The core plate 11 includes a face plate, a sandwich layer, and a face plate. The sandwich layer is preferably designed as a core tube array, that is, it includes a plurality of core tubes arranged at intervals. The upper and lower ends of the core tubes are flanged and brazed to the face plates respectively.

[0041] There are six pontoons 3 in the high-strength pontoon 3 platform, which are connected at an angle to form three vertices of a triangular structure. A wind power tower base 4 is provided at each of the three vertices. The wind power tower base 4 is a rectangular structure, including a tower base foot 5 and a truss connecting the tower base foot 5, wherein two tower base foots 5 are arranged on one pontoon 3, and the other two tower base foots 5 are arranged on another pontoon 3. A bracing rib 7 is also provided between each tower base and the pontoon 3. Two traction ropes 8 are provided on each of the pontoons 3 at the three vertices. The traction ropes 8 are Φ35 carbon ropes, and a total of 6 carbon ropes are used to connect the seabed.

[0042] In addition, the floating wind power system can also be connected to a cable (not shown in the figure) and a battery (not shown in the figure). The length of the cable is longer than the traction rope 8. The cable connects the battery and the wind turbine 1. In order to prevent the floating wind power system from being unable to adjust its direction when floating freely on the water and thus colliding with obstacles such as reefs or small ships, two sets of propellers (not shown in the figure) are added to the floating wind power system. The two sets of propellers are installed at any two vertices in the triangular structure and are connected to the battery. In this way, the floating forward direction can be adjusted in time by starting the propellers.

[0043] A wind turbine 1 is erected on each tower base, and the wind turbine 1 adopts the wind turbine disclosed in the Chinese invention patent application document 2023117672753. One of the wind turbines 1 is also equipped with a connecting truss 6 for strengthening strength on both sides of the inner angle facing the high-strength floating platform 2. The connecting truss 6 is composed of two sizes of steel pipes to provide optimal structural support and stability, enhance the overall structural rigidity, and better resist the complex offshore environment. The main connection between the wind turbine 1 and the buoy 3 is a floating frame rod 9 (Φ1020×12) with a diameter of 1020mm and a wall thickness of 12mm. The floating web rod 10 (Φ630×8) with a diameter of 630mm and a wall thickness of 8mm is used as a supporting structure to connect the buoy 3 and the Φ1020×12 steel pipe. These steel pipes provide additional support and stability for the main connecting truss. This double-layer truss design not only enhances the overall structural strength, but also ensures the stable operation of the wind turbine 1 under various sea conditions.

[0044] In this embodiment, the design of the floating wind power system adopts three wind turbines 1, and the total power generation capacity reaches 24MW. The buoy 3 structure uses a carbon steel buoy 3 (titanium steel, stainless steel, fiberglass, carbon fiber, pure titanium and other corrosion-resistant materials can also be used), with a diameter of 4m, a height of 4.536m, and an overall length of 60m. However, there are three buoys 3 as a connecting box of a triangular structure, and its length is extended to 62.4m, and the surface connected to another buoy 3 at the vertex is an inclined surface, so the length of each side of the equilateral triangle structure of the floating wind power system is 182.4m, and the side length of the equilateral triangle structure is greater than the height of the tower of a single wind turbine. The thickness of the core plate 11 is 268mm. The total weight of the entire wind power system is 3800 tons, including components such as tower cranes, blades and transformers. The floating wind power system has a total buoyancy of 9100 tons, and the surplus buoyancy reaches 5300 tons, accounting for 58.2% of the total buoyancy, to ensure the stability and safety of the facility during offshore operations.

[0045] The equilateral triangle structure adopted by the buoy 3 of this embodiment has a long span design with a side length of 182.4m, which makes the whole system have excellent anti-overturning performance. Even in extreme sea conditions, the long span layout of the triangular structure can provide sufficient restoring torque, so that the system will only tilt at a limited angle of no more than 15° without overturning. This long span design, combined with 58.2% of surplus buoyancy, ensures the stability of the system in various sea conditions.

[0046] The diameter of the wind rotor is 154m, the swept area of ​​each wind rotor reaches 18,600m2, and the total swept area of ​​the three wind rotors is 55,800m2, providing sufficient wind capture capacity. The rated wind speed of the system is set at 11m / s, and the cut-out wind speed is set at 20m / s to optimize the efficiency and safety of wind power generation.

[0047] The draft of the floating wind power system is 1.75m, and the height of the buoy 3 above the water surface is 2.7m, which ensures the stability of the system at sea and is also convenient for maintenance and operation. Through reasonable buoyancy design and weight distribution, the floating wind power system can maintain good working conditions in various sea conditions and give full play to its power generation potential.

[0048] The floating wind power system has significant advantages in terms of environmental protection and economy: the core plate 11 design not only greatly reduces the production labor, but also makes the structure simpler, thereby reducing maintenance costs. The density of the core plate 11 is 15 times lighter than that of steel, and it has a longer service life, which not only reduces the overall weight but also extends the service life of the system. In addition, due to the use of the prefabricated core plate 11 splicing process, the system significantly reduces the grinding and spraying works, further reducing costs and environmental impact, proving the great potential of the floating wind power system in the field of sustainable development and clean energy.

[0049] Example 2

[0050] like Figure 6-10 As shown, a floating wind power system comprises at least three wind turbines 1 and a high-strength floating platform 2 to form a wind power generation system; the high-strength floating platform 2 comprises a plurality of connected buoys 3.

[0051] Specifically, the high-strength floating platform 2 is a grid structure composed of multiple rectangular structures. A single rectangular structure includes four pontoons connected end to end. The pontoons 3 are made of core plates 11, and two adjacent pontoons 3 are fastened and connected by flanges and bolts. Each pontoon 3 is composed of at least three core plates 11.

[0052] The core plate 11 includes a face plate, a sandwich layer, and a face plate. The sandwich layer is preferably designed as a core tube array, that is, it includes a plurality of core tubes arranged at intervals. The upper and lower ends of the core tubes are flanged and brazed to the face plates respectively.

[0053] In this embodiment, the high-strength pontoon 3 platform includes nine rectangular structures, each of which has four vertices, and a wind turbine tower base 4 is provided at each vertex. The connection between two adjacent rectangular structures shares a vertex, a wind turbine tower base 4 and a pontoon 3. In addition to the threaded components connected between each wind turbine tower base 4 and the pontoon 3, a tower support 13 is also inclinedly arranged. The wind turbine tower base 4 is a rectangular structure. The pontoons 3 at the four vertices of the entire grid structure are each provided with two traction ropes (the position of the traction ropes refers to Example 1). The traction ropes are Φ35 carbon ropes, and a total of 8 carbon ropes are used to connect to the seabed. In addition, the floating wind power system can also be connected to cables and batteries. The length of the cable is longer than the traction rope, and the cable connects the battery and the wind turbine 1.

[0054] A wind turbine set 1 is mounted on each tower base, and the wind turbine set 1 adopts the wind turbine set disclosed in Chinese invention patent application document 2023117672753.

[0055] Each pontoon 3 is provided with a trapezoidal connecting truss 6 for supporting and reinforcing the wind turbine 1. The connecting truss 6 is composed of two sizes of steel pipes to provide optimal structural support and stability, enhance the overall structural rigidity, better resist the complex offshore environment, and the trapezoidal structure can better disperse and transfer loads. The main connection between the wind turbine 1 and the pontoon 3 is a floating frame rod 9 (Φ1420×19) with a diameter of 1420mm and a wall thickness of 19min. As a supporting structure connecting the floating frame rod 9 is a floating web rod 10 (Φ630×8) with a diameter of 630mm and a wall thickness of 8mm. The three trapezoidal connecting trusses 6 in the same row or column of the grid mechanism have a total length of 420m, and the top of the trapezoidal connecting trusses 6 is 340m in total. In each rectangular structure, a 40m long brace 12 is also provided between two adjacent connecting trusses 6 at a 45° angle. The 40m long brace arranged at a 45° angle strengthens the connection between adjacent connecting trusses, reduces structural vibration and deformation, and improves the reliability of the system in extreme weather. These steel pipes provide additional support and stability for the main connecting trusses. This double-layer truss design not only enhances the overall structural strength, but also ensures the stable operation of the wind turbine 1 in various sea conditions.

[0056] In this embodiment, the design of the floating wind power system adopts a total of 16 wind turbines 1, with a total power generation capacity of 128MW. Among them, the height between the motors of the four wind turbines 1 located in the center of the grid structure and the buoy 3 is higher than the height between the motors of other wind turbines and the buoy, and the height is 130m. The reason is that when the wind turbine is running, a turbulent wake will be generated downstream, and the wind speed in the wake area will decrease and the turbulence intensity will increase. If the downstream wind turbine is in the wake area of ​​the upstream wind turbine, the power generation efficiency will decrease and the fatigue load will increase. The wind turbines in the central area are more susceptible to the superposition of the wake of the surrounding wind turbines. Therefore, the higher installation height enables the central wind turbine to obtain high-altitude airflow with a higher wind speed, reducing the energy loss caused by the wake interference, which helps to improve the overall power generation efficiency of the entire system.

[0057] The pontoon 3 structure uses a carbon steel pontoon 3 (titanium steel, stainless steel, fiberglass, carbon fiber, pure titanium and other corrosion-resistant materials can also be used), with a diameter of 4m, a height of 4.536m, and an overall length of 160m. That is, after the nine rectangular structures are spliced ​​into a grid structure, the total length of each row and column of the grid structure is 480m long, and the diagonal length of the rectangular structure is greater than the height of the tower of a single wind turbine.

[0058] The buoy 3 of this embodiment adopts a large-span lattice structure design with a total length of 480m, which makes the system have excellent anti-overturning characteristics. Even in severe weather conditions, the large-span layout of the lattice structure can generate a huge restoring moment, and the maximum tilt angle of the system is limited to within 12°, effectively preventing the risk of overturning. This large-span design combined with 62.5% of surplus buoyancy provides a reliable stability guarantee for the system.

[0059] The thickness of the core plate 11 is 268mm. Each wind turbine 1 weighs 11,500 tons, including a 120t wind rotor, a 300t wind turbine 1, a 300t tower (Φ1020×20, both 110m high) and several other auxiliary parts. The floating wind power system has a total buoyancy of 48,000 tons, of which the total weight of the floating island is 18,000 tons (including 315,000 tons of buoys, 92,277 tons of floating frame rods, 10,325 tons of floating belly rods and other structures of 150 tons). The net buoyancy of the system reaches 30,000 tons, accounting for 62.5% of the total buoyancy. This significant surplus buoyancy design ensures the stability and safety of the facility under various sea conditions, greatly improving the reliability and efficiency of the system during offshore operations.

[0060] The diameter of the wind rotor is 154m, the swept area of ​​each wind rotor reaches 18,600m2, and the total swept area of ​​the three wind rotors is 55,800m2, providing sufficient wind capture capacity. The rated wind speed of the system is set at 11m / s, and the cut-out wind speed is set at 20m / s to optimize the efficiency and safety of wind power generation.

[0061] Example 3

[0062] like Figure 11-12 As shown, a floating wind power system includes a tall wind turbine 14 and a short wind turbine 15 that cooperate with a high-strength floating platform 2 to form a wind power generation system; the high-strength floating platform 2 includes a plurality of connected buoys.

[0063] Specifically, the high-strength floating platform 2 is a rectangular structure, which is formed by four pontoons connected end to end. The pontoons 3 are made of core plates 11, and two adjacent pontoons 3 are fastened and connected by flanges and bolts. Each pontoon 3 is 72 meters long. Tall fans 14 and short fans 15 are arranged opposite to each other on the diagonal line of the floating platform 2. The four right-angled inner sides of the high-strength floating platform 2 are all provided with tripods, wherein the large tripod 18 is arranged below the large tower 16, and the small tripod 19 is arranged below the small tower 17.

[0064] The large tripod 18 and the small tripod 19 are both designed with a truss structure. The total length of the large tripod 18 is 41946 mm, the total length of the small tripod 19 is 16535 mm, and the height of the two tripods is 4564 mm. The tall wind turbine 14 is installed on the buoy 3 and the large tripod 18 through the large tower 16, and the short wind turbine 15 is installed on the buoy 3 and the small tripod 19 through the small tower 17.

[0065] The specific structure of the high wind turbine 14 is as follows: the tower column on the large tower is 189m high, the tower column size is Φ820x16, and an auxiliary support system is provided on one side of the tower column. The auxiliary support system includes an auxiliary long support 20 set obliquely and auxiliary crossbars A21 and B22 set horizontally. The top of the auxiliary long support 20 is 100m away from the buoy 3, and the bottom is 30m away from the tower column, with a size of Φ820x16; the installation height of the auxiliary crossbar A21 is 41m, with a size of Φ630x12; the installation height of the auxiliary crossbar B22 is 65m, with a size of Φ325x8. The tower crane diameter of the high wind turbine 14 is Φ160m.

[0066] The specific structure of the short wind turbine 15 is as follows: the tower column on the small tower is 88m high, and the tower diameter is Φ160m, the same as the tall wind turbine 14. In the system design, a safety interval of 7410mm is reserved between two adjacent wind turbines.

[0067] The system has a buoyancy-to-weight ratio of 0.44 and a height above the water surface of 2.2m. The overall weight consists of: a total weight of 10,688t, of which the tower weighs 1,076t, the buoy 3 weighs 2,640t, and the wind turbine 1 weighs 4,740t.

[0068] The system ensures stability and reliability in the offshore environment through reasonable structural design and weight distribution. The staggered arrangement of tall wind turbines 14 and short wind turbines 15 not only improves the efficiency of wind energy utilization, but also reduces wake interference. The overall structure not only ensures the strength requirements of the system, but also achieves an economic balance. Compared with traditional fixed offshore wind power, this system has the advantages of convenient construction and controllable costs, and is suitable for promotion and application in sea areas of different water depths.

[0069] In summary, the floating wind power systems of Embodiment 1, Embodiment 2 and Embodiment 3 can achieve the following beneficial effects:

[0070] (1) By setting at least three wind turbines in conjunction with a high-strength floating platform to form a wind power generation system, where the span of the high-strength floating platform is greater than or equal to the height of the wind power tower (Example 1 uses an equilateral triangle with a side length of 182.4m, and Example 2 uses a 480m large-span grid structure), a safe and stable layout of a large-scale deep-water wind power system is achieved. Compared with the traditional single-machine floating wind power system and its span design of only 1 / 5-1 / 6 of the tower height, the present invention successfully integrates multiple wind turbines (3 turbines in Example 1 and 16 turbines in Example 2), significantly improving the system's anti-overturning ability. Its large-span design allows the system to tilt at most a limited angle under extreme conditions (maximum 15° in Example 1 and maximum 12° in Example 2), and will not overturn, fundamentally improving the system's safety.

[0071] (2) The buoy design of the core plate box structure is innovatively adopted (adopting a panel-sandwich layer-panel sandwich structure, with the sandwich layer being a core tube array), realizing an integrated solution of structural support and buoyancy. Compared with the traditional buoy design that only solves the buoyancy problem, the buoy of the present invention not only serves as a support structure but also provides buoyancy (Example 1 provides 9,100 tons of buoyancy, and Example 2 provides 48,000 tons of buoyancy), significantly improving the overall performance of the system. At the same time, the modular design (each buoy consists of at least three core plates) not only simplifies the production process and reduces the amount of labor, but also facilitates transportation and on-site assembly, greatly reducing the difficulty of construction and maintenance costs.

[0072] (3) Compared with the traditional design scheme that relies on cable fixation, the present invention provides the main stable support through the structural characteristics of the large-span floating platform, and the cables are only used as auxiliary fixing devices, which significantly improves the stability and reliability of the system under severe sea conditions and provides a safer and more efficient solution for deep-water wind power development.

[0073] (4) Through the high and low staggered wind turbine layout scheme (high wind turbine tower 189m, low wind turbine tower 88m), combined with the differentiated design of large and small tripods (large tripod 41946mm, small tripod 16535mm), the three-dimensional utilization of wind energy is achieved. This design not only effectively reduces the wake interference between wind turbines and improves the overall power generation efficiency of the system, but also optimizes the distribution of platform carrying capacity, making the structure more reasonable.

[0074] (5) An innovative multi-level auxiliary support system for high wind turbines (including auxiliary long supports, auxiliary crossbars A and auxiliary crossbars B) was adopted to form an overall coordinated structural support system. Through support components of different heights and specifications (Φ820x16, Φ630x12, Φ325x8, etc.), the economic efficiency of materials was achieved while ensuring structural strength, providing a better engineering practice solution for large offshore wind power systems.
