[0047] Nacelle-1, Wind turbine-2, Support structure-3, Columnar float-4, Mooring point-5, Spoiler-6. Detailed Implementation
[0048] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0049] To adapt to the marine environment and enable the installation of wind turbine generators in the ocean, embodiments of the present invention provide floating wind turbine generators; specifically, refer to... Figure 1 ;like Figure 1 As shown, the floating wind turbine generator set may include: nacelle 1, wind turbine 2, support structure 3, yaw system, spoiler 6, drive unit and multiple cylindrical floats 4;
[0050] The nacelle 1 is connected to the wind turbine 2; the nacelle 1 is connected to multiple columnar floating bodies 4 through the support structure 3.
[0051] The support structure 3 includes multiple connecting units; among the multiple connecting units, the two ends of one connecting unit are vertically connected to the cabin 1 and the corresponding columnar float 4 respectively, and the two ends of the other connecting units are connected to the cabin 1 and the corresponding columnar float 4 respectively, and the other connecting units are at an angle of θ° with the cabin 1 and the corresponding columnar float 4; 0 < θ° < 90°;
[0052] Yaw system, used to adjust the angle of wind turbine 2 and / or nacelle 1;
[0053] The spoiler 6 is arranged circumferentially along the columnar float 4; the spoiler 6 is connected to the columnar float 4 by a bearing, and the spoiler 6 is retractable relative to the columnar float 4; the spoiler 6 is connected to the actuator.
[0054] A driver for driving the spoiler 6 around the cylindrical float 4.
[0055] In this embodiment of the invention, the floating wind turbine generator set may include a nacelle 1, a wind turbine 2, a support structure 3, a yaw system, and multiple cylindrical floats 4. The nacelle 1 can be connected to the wind turbine 2. When the wind turbine 2 rotates, the rotational kinetic energy is transmitted through the shaft of the wind turbine 2 to a gearbox inside the nacelle 1. The gearbox transmits the increased rotational speed to the generator. The generator contains one or more magnets and a coil (or stator). When the magnets rotate, they generate a changing magnetic field in the stator coil, thereby inducing an electric current.
[0056] The ocean differs from land; there is no ground surface for wind turbines to be installed on the sea surface; therefore, multiple cylindrical floats 4 are required to allow the nacelle 1 and the wind turbine 2 to be placed on the sea surface. For example, the design and function of the cylindrical floats 4 are mainly focused on providing buoyancy, stability, and structural support.
[0057] The main function of the cylindrical float 4 is to provide sufficient buoyancy to support the weight of the nacelle 1, wind turbine 2, support structure 3, etc. The cylindrical float 4 can be made of lightweight but high-strength materials, such as high-density polyethylene, steel, or concrete.
[0058] To ensure stability, the columnar float 4 can be designed with a certain width and height to increase the volume of its underwater portion, thereby improving its resistance to wind, waves and tilting.
[0059] The columnar float 4 is connected to the nacelle 1, wind turbine 2, etc. via the support structure 3 to provide necessary structural support to the nacelle 1, wind turbine 2, etc.
[0060] In addition, due to long-term exposure to the marine environment, the columnar float 4 needs to have good corrosion resistance and durability.
[0061] In this embodiment of the invention, the floating wind turbine generator set has no tower. The nacelle 1 of the floating wind turbine generator set can be fixedly connected to multiple columnar floating bodies 4 through the support structure 3. The support structure 3 can include multiple connecting units, which can be truss structures or iron pipes.
[0062] In practical applications, the two ends of one of the multiple connecting units can be perpendicular to the cabin 1 and the corresponding cylindrical float 4, respectively, and are fixedly connected to the cabin 1 and the corresponding cylindrical float 4, respectively.
[0063] Besides the main connecting unit, the two ends of other connecting units can be connected to the nacelle 1 and the corresponding cylindrical float 4, respectively, and the other connecting units are at an angle of θ° to the nacelle 1 and the corresponding cylindrical float 4; 0 < θ° < 90°. This design can improve the stability of the floating wind turbine generator.
[0064] In some feasible embodiments, the floating wind turbine may also include a yaw system that can be used to adjust the angle of the rotor 2 and / or nacelle 1 to ensure that the rotor 2 always faces the wind direction in order to maximize the wind energy capture efficiency.
[0065] For example, a yaw system may include the following components:
[0066] Yaw bearing: The yaw bearing is the core component of the yaw system, allowing the nacelle 1 to rotate relative to the connecting unit. The yaw bearing is typically designed as a large annular structure, mounted on top of the connecting unit and connected to the base of the nacelle 1.
[0067] Yaw actuator: The yaw actuator is responsible for driving the yaw bearing to rotate, thereby adjusting the orientation of the nacelle 1. The yaw actuator can be electric, hydraulic, or pneumatic, depending on the design requirements and application scenario.
[0068] Yaw control system: The yaw control system is the "brain" of the yaw system. It receives signals from the wind direction sensor and controls the operation of the yaw actuator according to preset algorithms and logic. The control system typically includes sensors, controllers, and actuators.
[0069] Yaw brake: The yaw brake is used to provide the necessary braking force during yaw adjustments to prevent the nacelle 1 from rotating excessively under wind conditions. The brake can be mechanical, hydraulic, or electromagnetic.
[0070] In the yaw system, sensors (such as wind vanes) are mounted on top of the nacelle 1 or connecting unit to detect changes in wind direction in real time. The detected wind direction signal is transmitted to the yaw control system. Based on the received wind direction signal, the yaw control system calculates the required adjustment angle and sends a command to the yaw actuator. Following the control system's command, the yaw actuator drives the yaw bearing to rotate, thereby adjusting the orientation of the nacelle 1 and the wind turbine 2 to face the new wind direction. Once the wind turbine 2 is in the correct orientation, the yaw brake applies braking force to ensure the nacelle 1 remains stable in the new position.
[0071] In one embodiment of the present invention, the yaw control angle of the yaw system can be in the range of -20° to 20°. For example, when the calculated angle to be adjusted is within the range of -20° to 20°, the yaw system can adjust the nacelle 1 and / or the wind turbine 2 so that the wind turbine 2 is adjusted to the correct direction.
[0072] In one embodiment of the present invention, each columnar float 4 can be connected in pairs by a truss structure or a support frame.
[0073] In one embodiment of the present invention, such as Figure 1As shown, multiple cylindrical floats 4 can be connected to mooring points 5 via support rods. For example, all cylindrical floats 4 can be fixedly connected to mooring points 5 via support rods, or only some cylindrical floats 4 can be fixedly connected to mooring points 5 via support rods; this embodiment of the invention does not impose any limitations on this.
[0074] Mooring point 5 refers to the connection point used to fix and stabilize the floating wind turbine generator. The mooring system connects the floating wind turbine generator to the seabed or other fixed structures through mooring point 5 to resist environmental loads such as wind, waves, and currents, ensuring the stability and safety of the floating wind turbine generator.
[0075] A mooring system can consist of the following structures:
[0076] Mooring cable: A mooring cable is a rope or chain that connects a floating wind turbine to the seabed or other fixed structures. Mooring cables are typically made of high-strength materials such as steel cables, synthetic fiber cables (such as polyester and nylon), or composite material cables.
[0077] Anchoring System: The anchoring system is the fixed end of the mooring cable on the seabed, and can be a gravity anchor, suction anchor, pile anchor, or other types of anchor. The design of the anchoring system depends on the seabed geological conditions and environmental loads.
[0078] Mooring Point 5: Mooring point 5 is a specific location on a floating wind turbine generator used to connect the mooring cable. Mooring point 5 is typically designed with a structure capable of withstanding high tensile and dynamic loads to ensure a reliable connection of the mooring cable.
[0079] Tensioning system: The mooring system may also include a tensioning system for adjusting the tension of the mooring cable to accommodate different environmental conditions and the displacement of the floating wind turbine.
[0080] In one embodiment of the present invention, such as Figure 2 As shown, mooring point 5 can be set up either upwind or upwind.
[0081] In practical applications, when a floating wind turbine is subjected to wind or current, it will generate a drift force towards the leeward or downstream side. Setting the mooring point 5 upwind or upstream can utilize the tension of the mooring cable to resist this drift force, thereby reducing the lateral movement of the floating wind turbine.
[0082] In addition, wind and current often exert asymmetrical loads on floating wind turbines, especially when wind and current speeds change. By setting mooring point 5 upwind or upwind, the mooring cable can distribute the load evenly on the floating wind turbine, avoiding local overload and improving overall stability.
[0083] Furthermore, the tension of the mooring cable provides restoring force, helping the floating wind turbine return to its equilibrium position after being subjected to external disturbances. Setting mooring point 5 upwind or upstream maximizes the restoring force of the mooring cable, enhancing the floating wind turbine's ability to resist external disturbances.
[0084] Floating wind turbines experience periodic motion under the influence of wind, waves, and currents, which can lead to fatigue damage to the mooring cables and the floating wind turbine itself. Optimizing the location of mooring point 5 can reduce unnecessary vibration and swaying, extending the service life of both the mooring system and the floating wind turbine.
[0085] Marine environmental conditions (such as wind direction and current speed) may change constantly. Setting mooring point 5 upwind or upwind can help the mooring system better adapt to these changes and maintain the stability of the floating wind turbine.
[0086] In some feasible embodiments, when the offset angle is too large, the yaw system alone may not be able to adjust the angle of the wind turbine 2; therefore, the floating wind turbine provided in this embodiment of the invention may also include a spoiler 6 and a driver.
[0087] The spoiler 6 can be arranged circumferentially along the columnar float 4, and the spoiler 6 and the columnar float 4 are connected by bearings; the spoiler 6 can rotate around the columnar float 4, thereby adjusting the angle of the floating wind turbine generator set, and thus adjusting the angle of the wind turbine 2.
[0088] Specifically, the spoiler 6 can be connected to the driver; when the angle of the wind turbine 2 is detected to deviate from the current wind direction by more than -20° to 20°, the driver can control the spoiler 6 to rotate, thereby adjusting the angle of the floating wind turbine generator and thus adjusting the angle of the wind turbine 2.
[0089] In one embodiment of the present invention, the spoiler 6 can be arranged uniformly along the circumference of the columnar float 4.
[0090] In some feasible embodiments, the spoiler 6 may also be a retractable structure, so that it can be retracted into the cylindrical float 4 by a driver when it is not needed, and extended out of the cylindrical float 4 by a driver when it is needed. This embodiment of the invention does not limit this.
[0091] In one embodiment of the present invention, the floating wind turbine is a downwind turbine. Specifically, a downwind turbine can refer to a wind turbine where the rotor 2 is designed to rotate in the downstream direction of the wind. Compared with a conventional upwind turbine, the rotor 2 of a downwind turbine is located on the leeward side of the nacelle 1, meaning that the wind first blows over the support structure 3 before reaching the rotor 2.
[0092] Characteristics of leeward turbine units: One potential advantage of leeward turbine units is the natural yaw effect. Since the rotor 2 is located on the leeward side of the tower, it naturally follows wind direction changes, reducing the need for an active yaw system. This simplifies the unit's control system and reduces maintenance costs. In leeward turbine units, the tower can provide some degree of shelter for the rotor 2, reducing the direct wind load on it. This may help reduce fatigue damage to the rotor 2 and extend its service life. The rotor 2 of a leeward turbine unit may experience a faster dynamic response to wind speed changes because it is directly exposed to the changing wind speed. This may require more complex control strategies to manage the rotor 2's rotational speed and power output.
[0093] In this embodiment of the invention, the floating wind turbine generator set includes: a nacelle 1, a wind turbine 2, a support structure 3, a yaw system, and multiple cylindrical floats 4; wherein, the nacelle 1 is connected to the wind turbine 2; the nacelle 1 is connected to the multiple cylindrical floats 4 through the support structure 3; the support structure 3 includes multiple connecting units; among the multiple connecting units, one connecting unit has its two ends vertically connected to the nacelle 1 and the corresponding cylindrical float 4, respectively, and the two ends of the other connecting units are respectively connected to the nacelle 1 and the corresponding cylindrical float 4, and the other connecting units are at an angle of θ° with the nacelle 1 and the corresponding cylindrical float 4; 0 < θ° < 90°; the yaw system is used to adjust the angle of the wind turbine 2 and / or the nacelle 1. Through this embodiment of the invention, the installation of a wind turbine generator on the ocean can be realized.
[0094] Furthermore, a unique support structure 3 is employed: one of the connecting units is vertically connected at both ends to the nacelle 1 and the corresponding columnar float 4, providing direct vertical support and helping to transfer and distribute vertical loads, such as the weight of the nacelle 1 and the wind turbine 2. The other connecting units are also connected at both ends to the nacelle 1 and the corresponding columnar float 4, and these connecting units are at an angle of θ° to the nacelle 1 and the corresponding columnar float 4, where 0 < θ° < 90°; this inclined connecting unit provides additional structural support, helping to resist lateral forces and torques, and enhancing the stability of the entire structure.
[0095] In addition, the yaw system can be set up to adjust the angle of the wind turbine 2 when the angle of the wind turbine 2 in the floating wind turbine is inconsistent with the wind direction, so as to ensure that the wind turbine 2 always faces the wind direction and maximize the wind energy capture efficiency.
[0096] Reference Figure 3 The diagram illustrates a step flowchart of a control method for a floating wind turbine generator set according to an embodiment of the present invention. The floating wind turbine generator set includes: a nacelle, a wind turbine, a support structure, a yaw system, a spoiler, and multiple cylindrical floats.
[0097] The nacelle is connected to the wind turbine; the nacelle is connected to multiple cylindrical floating bodies through a support structure.
[0098] The supporting structure includes multiple connecting units; among the multiple connecting units, the two ends of one connecting unit are vertically connected to the engine room and the corresponding cylindrical float respectively, and the two ends of the other connecting units are connected to the engine room and the corresponding cylindrical float respectively, and the other connecting units are at an angle of θ° with the engine room and the corresponding cylindrical float; 0 < θ° < 90°;
[0099] Yaw system, used to adjust the angle of the wind turbine;
[0100] The spoilers are arranged circumferentially along the columnar float; the spoilers are connected to the columnar float via bearings, and the spoilers are retractable relative to the columnar float; the spoilers are connected to the actuator.
[0101] The control of this floating wind turbine generator may include the following steps:
[0102] Step 301: Detect the current wind direction.
[0103] In practical applications, the current wind direction of the environment in which the floating wind turbine is located can be detected by sensors (such as wind vanes) in the yaw system.
[0104] Step 302: When the current wind direction does not match the current angle of the wind turbine, control the spoiler to adjust the angle of the wind turbine.
[0105] After detecting the current wind direction, it can be determined whether the current wind direction matches the current angle of the wind turbine. If the current wind direction does not match the current angle of the wind turbine, a command can be sent to the drive to control the spoiler to adjust the angle of the wind turbine so that the wind turbine always faces the wind direction, thereby maximizing the wind energy capture efficiency.
[0106] In this embodiment of the invention, the current wind direction is detected; when the current wind direction does not match the current angle of the wind turbine, the spoiler is controlled to adjust the angle of the wind turbine. Through this embodiment, the angle of the wind turbine in a floating wind turbine generator can be adjusted when the wind direction is inconsistent with the wind direction, ensuring that the wind turbine always faces the wind direction to maximize wind energy capture efficiency.
[0107] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.
