Description

Floating foundation and wind turbine with anti-sway control

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202410220741.4 and application date of February 28, 2024, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present application relates to the technical field of floating foundations, and in particular to a floating foundation with anti-sway control and a wind turbine generator set. Background Art

[0004] Offshore wind energy resources are abundant, power generation is stable, and it is adjacent to load centers, making it an important supporting power source for achieving the dual-carbon strategy.

[0005] Currently, offshore wind farms are almost exclusively fixed-type turbines. However, when water depths exceed 50 meters, the cost of existing fixed wind turbine foundations no longer meets the requirements for low-cost, large-scale development. Deep-sea wind resources are estimated to be 100 gigawatts, twice the nearshore wind resources, offering enormous development potential. As offshore wind power development gradually shifts from nearshore to deep-sea, floating wind power is an inevitable option for economically viable wind energy development in deepwater areas.

[0006] In deep sea areas, the wind force is relatively high, which can easily cause the tilt angle of the floating foundation to increase. This will not only increase the structural load on the wind turbine, but also affect the stability and power generation efficiency of the wind turbine system. In the relevant technical system, the platform's longitudinal tilt angle range is mainly adjusted by an active ballast adjustment system to improve the stability of the floating foundation structure of the offshore wind turbine. The active ballast adjustment in the relevant technology mainly uses a water pump to adjust the water volume. The adjustment speed is related to the flow rate of the water pump. It is limited by the performance of the ballast pump and the length of the ballast pipeline. The response speed is slow and the energy consumption is high during operation. The production cost is high, resulting in reduced stability of the overall control system and restricting its engineering application. Summary of the Invention

DETAILED DESCRIPTION

[0052] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present application, but should not be understood as limiting the present application.

[0053] As shown in Figures 1 to 4, the floating foundation 100 with anti-roll control according to an embodiment of the present application includes a base platform 1, guide rods 2, counterweights 4 and drive components 3. There are multiple guide rods 2, which are arranged on the base platform 1, and the projections of at least some of the guide rods 2 on the horizontal plane are arranged to intersect.

[0054] The counterweight 4 is arranged on the guide rod 2 and is movable along the guide rod 2; the driving component 3 is connected to the base platform 1 and the counterweight 4, and the driving component 3 is used to drive the counterweight 4 to move along the guide rod 2 to adjust the center of gravity position of the base platform 1.

[0055] It should be understood that the projections of some or all of the guide rods 2 on the horizontal plane are arranged to intersect (the projections directly intersect or the extension lines of the projections intersect). By adjusting the positions of the counterweights 4 on different guide rods 2, the center of gravity position of the floating foundation can be adjusted, and the center of gravity position of the floating foundation can be adjusted more accurately by combining the positions of different counterweights 4.

[0056] For example, there can be two guide rods 2, and the projections of the two guide rods 2 on the horizontal plane are intersecting, for example, arranged in an X-shaped cross. The intersection angle of the projections of the two guide rods 2 on the horizontal plane is between 40° and 90°, which facilitates the adjustment of the center of gravity.

[0057] When the number of guide rods 2 is three or more, the projections of some guide rods 2 on the horizontal plane are parallel, and the projections of some guide rods 2 on the horizontal plane intersect. The position combination of the counterweight blocks on more guide rods 2 can improve the adjustment of the center of gravity position of the floating foundation 100 with anti-roll control, thereby improving the adjustment and control of the stability of the floating foundation 100 with anti-roll control, and realizing anti-roll control of the floating foundation.

[0058] The floating foundation 100 with anti-roll control according to the embodiment of the present application can adjust the center of gravity of the floating foundation 100 with anti-roll control by adjusting the position of the counterweight 4, thereby improving the stability of the structure.

[0059] As shown in Figures 1 and 2, in some embodiments, the driving component 3 includes a first driver 31 and a first rope 32. The first driver 31 is provided on the base platform 1, and the first rope 32 is connected between the first driver 31 and the counterweight 4. It should be understood that the first driver 31 is a winch, and the first rope 32 is a steel strand. The winch or the unwinding of the steel strand can be used to pull the counterweight 4 to move on the guide rod 2.

[0060] In some embodiments, in order to adjust the position of the counterweight 4 on the guide rod 2, two sets of driving components 3 are provided for each counterweight 4, and the two sets of driving components 3 act synchronously. However, when adjusting, one of the driving components 3 reels in the steel strand and the other driving component 3 releases the steel strand to prevent the counterweight 4 from being controlled by the pulling of the steel strand.

[0061] Alternatively, the guide rod 2 can be set at an angle, so that one end of the guide rod 2 is higher than the other end of the guide rod 2 in the vertical direction, and the counterweight 4 will automatically slide downward due to gravity. At this time, a set of driving components 3 can be configured to pull the counterweight 4 to slide upward along the guide rod 2, so as to prevent the counterweight 4 from sliding freely on the guide rod 2 in some sections without being controlled by the steel wire rope.

[0062] In some embodiments, the drive component 3 includes a second driver and a lead screw. The second driver is disposed on the base platform 1, one end of the lead screw is in driving connection with the second driver, and a nut is disposed on the counterweight 4, which is in driving connection with the lead screw. It should be understood that the counterweight 4 slides axially on the guide rod 2, but does not rotate circumferentially along the guide rod 2. In this case, when the lead screw cooperates with the nut on the counterweight 4, the rotation of the lead screw can drive the counterweight 4 to slide along the guide rod 2.

[0063] In some embodiments, there is a limiting surface between the guide rod 2 and the counterweight 4. For example, the cross section of the guide rod 2 is rectangular, the counterweight 4 has a rectangular hole, and the counterweight 4 is mounted on the guide rod 2 through the rectangular hole.

[0064] In some embodiments, the driving component 3 includes a power push rod, one end of which is connected to the base platform 1, and the other end of which is connected to the counterweight 4. It should be understood that the power push rod can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, and the power push rod is used to drive the counterweight 4 to move on the guide rod 2.

[0065] In some embodiments, the floating foundation 100 with anti-roll control further includes a detection system and a control system. The detection system is used to obtain response characteristics of the floating foundation 100 with anti-roll control. The control system is connected to the detection system and the driving component 3. The control system is used to receive and process the response characteristics to control the action of the driving component 3.

[0066] It should be understood that the detection system is used to obtain signals such as the inclination angle of the floating foundation, so that when the inclination exceeds a certain threshold, the center of gravity of the floating foundation can be adjusted by adjusting the position of the counterweight 4, thereby adapting to the current external environment, reducing the swaying of the floating foundation, and improving the stability of the system.

[0067] Alternatively, the acceleration response of the floating foundation is measured by an acceleration sensor, and the frequency of the rocking mode of the floating foundation is identified through spectrum analysis (such as short-time Fourier transform, Hilbert-Huang transform, etc.), and the center of gravity position of the floating foundation is adjusted by adjusting the position of the counterweight 4.

[0068] In some embodiments, during use, a method for adjusting the floating foundation 100 for anti-rolling control is also included. The method for adjusting the floating foundation 100 for anti-rolling control specifically includes the following steps:

[0069] S101 : Acquire response characteristics of the floating foundation 100 with anti-roll control under external environmental excitation.

[0070] Due to the complex sea conditions in deep sea areas, there are complex environmental stimuli with different characteristics such as wind, waves, and currents, which can easily lead to an increase in the tilt angle of the floating foundation. Therefore, the response characteristics of the floating foundation in the current environment are determined by combining the impact of the wind, wave, and current levels on the floating foundation, or by obtaining other response characteristics of the floating foundation. The center of gravity position of the floating foundation is adjusted according to the corresponding response characteristics, thereby more effectively controlling the stability of the floating foundation.

[0071] After obtaining the inclination angle of the floating foundation, it can be determined whether the inclination angle of the floating foundation exceeds a preset threshold. If so, the center of gravity position of the floating foundation is adjusted; if not, the center of gravity position of the floating foundation may not be adjusted.

[0072] S102 : Calculate the required adjusted center of gravity position of the floating foundation 100 for anti-roll control based on the response characteristics.

[0073] The response characteristic of the floating foundation under external excitation can be the tilt angle of the floating foundation, and / or the acceleration response of the floating foundation can be measured by an acceleration sensor, and the frequency of the swaying mode of the floating foundation can be identified through spectrum analysis (such as short-time Fourier transform, Hilbert-Huang transform, etc.). Based on the frequency of the swaying mode of the floating foundation, the center of gravity position of the floating foundation is determined, and the swaying of the floating foundation is controlled.

[0074] By obtaining the response characteristics under external environmental excitation in real time or periodically, the stability of the floating foundation can be continuously monitored and adjusted, the center of gravity position of the floating foundation can be adjusted, and the stability of its structure can be optimized.

[0075] S103: The driving component 3 drives the counterweight 4 to adjust the center of gravity of the anti-rolling floating foundation 100. The center of gravity of the counterweight superimposed on the foundation platform 1 is determined by the position combination of the counterweight 4 on the guide rod 2, thereby adjusting the center of gravity of the floating foundation.

[0076] As shown in Figures 3 and 4, in some embodiments, the driving component 3 includes a float 33, a first bracket 34, a second rope 35 and a pulley assembly 36, one end of the first bracket 34 is connected to the float 33, the other end of the first bracket 34 is hinged to the base platform 1, the float 33 can swing relative to the base platform 1, one end of the second rope 35 is connected to the float 33, the pulley assembly 36 is provided on the base platform 1, and the other end of the second rope 35 is guided by the pulley assembly 36 and connected to the counterweight 4; when the float 33 swings relative to the base platform 1, the float 33 drives the counterweight 4 to move on the guide rod 2.

[0077] It should be understood that when the floating foundation is placed in a liquid environment such as seawater, the buoyancy of the floating member 33 by the seawater can make the counterweight 4 be in the initial position. When the floating foundation tilts, the amount of water displaced by the floating member 33 near the sinking end of the floating foundation will gradually increase, thereby driving the first bracket 34 to swing relative to the base platform 1. At this time, the counterweight 4 can be driven to slide on the guide rod 2 through the second rope 35, thereby adjusting the position of the counterweight 4 on the guide rod 2, which can achieve adaptive adjustment without the need for other energy sources to drive.

[0078] Compared to the active ballast system of the floating foundation in the related art, the embodiment of the present application does not require the installation of water pumps, pipelines, drive systems, control systems and other equipment, is not affected by the flow rate of the water pump, and has a fast response speed. Therefore, the present application realizes the spontaneous mechanical adjustment of the position of the counterweight 4 by setting a floating member 33, realizes the real-time rapid adjustment of the center of gravity, and realizes the function of adjusting the posture of the floating foundation. The mechanical adjustment method also eliminates the use of sensors and motors, is more economical, has stable performance and is easy to maintain. Therefore, the floating foundation of the present application can adjust the stability of the floating foundation of the offshore wind turbine 200 in a purely mechanical way, and has broad engineering application prospects.

[0079] The floating member 33 may be a buoy, a float or other equipment that can float on the sea surface.

[0080] The counterweight 4 is a counterweight block with high density and high quality, for example, it is supported by metal material, or a metal box is filled with concrete blocks, or a reinforced concrete block is directly used as the counterweight 4.

[0081] As shown in Figures 1 to 4, in some embodiments, there are at least three guide rods 2, which are arranged on the base platform 1 at intervals along the circumferential direction, with one end of the guide rod 2 being arranged close to the middle of the base platform 1, and the other end of the guide rod 2 being arranged close to the circumference of the base platform 1.

[0082] In order to improve the effect of adjusting the floating platform, the number of guide rods 2 in the embodiment of the present application is at least three, for example, the number of guide rods 2 is 3, 4, 6, 9 or more.

[0083] The guide rods 2 can be arranged in a circular arrangement, with the middle of the base platform 1 as the center point, and the guide rods 2 scattered around the center point in the circumferential direction. In this case, the driving component 3 is used to drive the counterweight 4 from the middle of the base platform 1 to the circumference of the base platform 1, or to drive the counterweight 4 from the circumference of the base platform 1 to the middle of the base platform 1.

[0084] As shown in Figures 1 to 4, in some embodiments, a crash pad 21 is provided at the end of the guide rod 2. In order to prevent the counterweight 4 from directly impacting the base platform 1 during movement and to prevent the base platform 1 from being damaged, an crash pad 21 is provided in the embodiment of the present application to play a buffering role. The crash pad 21 can be a rubber pad, for example, a waste tire can be used as the crash pad 21.

[0085] As shown in Figures 1 to 4, in some embodiments, the base platform 1 includes multiple pontoons and a frame 13, the multiple pontoons are arranged at intervals, the frame 13 is connected between the multiple pontoons, and the guide rod 2 is connected between the corresponding two pontoons, or the guide rod 2 is provided on the frame 13.

[0086] It should be noted that the basic platform 1 is composed of a combination of buoys and a frame 13. Multiple buoys are arranged in a circular or rectangular array. The frame 13 is arranged between the buoys to form a stable integrated structure, which is convenient for arranging wind power equipment or other offshore equipment on the basic platform 1. The buoys are used to provide buoyancy so that the basic platform 1 can float on the sea.

[0087] Furthermore, the number of the buoys is 3, 4, 6, 7 or 10.

[0088] The guide rod 2 may be disposed between adjacent buoys, or the guide rod 2 may be disposed on the frame 13 as a part of the frame 13 .

[0089] As shown in Figures 1-4, in some embodiments, the buoys include a central buoy 11 and side column buoys 12. There are multiple side column buoys 12, which are arranged circumferentially around the central buoy 11 at intervals. The frame 13 is provided between the central buoy 11 and the side column buoys 12. It should be understood that the central buoy 11 is located in the middle of the base platform 1, the side column buoys 12 are located circumferentially around the base platform 1, and the guide rods 2 can be provided between the central buoy 11 and each side column buoy 12.

[0090] In some embodiments, the floating foundation further includes heave plates 14, with multiple heave plates 14 disposed between adjacent buoys. The provision of multiple heave plates 14 can effectively suppress movement of the floating foundation and improve stability.

[0091] In some embodiments, a heave plate 14 is provided between adjacent buoys, and the heave plate 14 is located at the bottom of the buoys.

[0092] The anti-rolling floating foundation 100 also includes a mooring system 15, which comprises multiple mooring lines, one end of which is connected to the frame 13 or buoy, and the other end of which is connected to the seabed. These multiple mooring lines can be arranged along the circumference of the floating foundation, improving the foundation's stability and wind resistance. They can also constrain the floating foundation's position and movement. Adjusting the center of gravity of the floating foundation can also reduce the stress-bearing capacity of the mooring lines, thereby alleviating the impact loads on the mooring lines caused by the oscillation or excessive tilt of the floating foundation, thereby preventing any impact on the strength and fatigue of the mooring lines.

[0093] In some embodiments, the mooring line is a steel cable or an iron chain, and the mooring line is connected to the seabed through a gravity anchor, a suction anchor, a grip anchor or a pile anchor.

[0094] As shown in Figures 1-8, a wind turbine 200 according to an embodiment of the present application includes a floating foundation 100 with anti-roll control, a tower 5, and a blade assembly 6, as described in any of the aforementioned embodiments. The tower 5 is mounted on the floating foundation 100, and the blade assembly 6 is mounted on top of the tower 5. Arranging the tower 5 and blade assembly 6 on the floating foundation to form wind turbine 200 facilitates the development of offshore wind power in deepwater areas, adapts to complex deepwater conditions, and effectively responds to complex external environmental stimuli such as wind, waves, and currents.
