[0002] In offshore wind power development, the stability and power generation efficiency of floating wind power platforms are crucial for achieving efficient and safe operation. Active ballast systems, as an important technical means to ensure the stability of floating wind power platforms, can monitor the tilt angle of the platform in real time. When the tilt angle exceeds a set threshold, the system dynamically adjusts the distribution of solid or liquid ballast within the platform to correct the tilt caused by environmental factors such as wind, waves, and currents. This maintains the stability of the floating wind power platform's attitude and reduces the adverse effects of tilting, such as reduced turbine power generation efficiency and increased load on the tower base.

[0003] Currently, the initial and target ballast angles in active ballast systems are primarily set based on human experience. While this approach is simple to operate, it suffers from limitations in accuracy and adaptability. In the complex marine environment, parameters set solely based on experience often fail to accurately match real-time operating conditions, leading to untimely or inappropriate platform attitude control. This, in turn, affects power generation efficiency, accelerates equipment fatigue, and limits the control effectiveness and reliability of active ballast systems in practical applications.

Furthermore, it adaptively determines the target load adjustment angle based on the current wind speed and direction, aiming to maximize the wind turbine's power generation, thus overcoming the limitation of the active ballast system's effectiveness caused by a fixed angle. This method enables dynamic adaptive adjustment of the load adjustment angle, compensating for the negative impact of a fixed load adjustment angle on wind turbine power generation efficiency and platform stability in existing active ballast systems.

[0020] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0021] This application discloses an adaptive load adjustment method for an active ballast system of a floating wind turbine platform. The method includes the following steps; please refer to [reference needed]. Figure 1 The flowchart shown and Figure 2 The diagram shows the structure of a floating wind turbine platform. The platform includes a wind turbine rotor (1), a nacelle (2), a tower (3), a foundation (4), and a mooring system (5). The mooring system 5 provides positional constraints for the foundation (4). The bottom of the tower (3) is fixed to the foundation (4), and the top of the tower (3) is fixed to the nacelle (2). The nacelle (2) is connected to the wind turbine rotor (1). The floating wind turbine platform is equipped with a body coordinate system. When no tilting occurs in the initial state, The axis is perpendicular to the horizontal plane and pointing upwards. The plane is parallel to the horizontal plane, and is usually oriented with the direction from the center of the platform to the bow of the platform as... The positive axis is defined as the direction from the center of the platform to the port side of the platform. Positive axis.

[0022] Step 1: During the operation of the floating wind power platform in the actual marine environment, collect the operating parameters of the floating wind power platform at various sampling times according to the predetermined sampling frequency, including: (1) The real-time tilt angle of the floating wind power platform is collected by the platform attitude sensor. and real-time pitch angle The measured real-time tilt angle The floating wind power platform revolves around the body coordinate system The rotation angle of the shaft, the real-time pitch angle The floating wind power platform revolves around the body coordinate system The rotation angle of the shaft, Indicates time.

[0023] Additionally, regarding the real-time tilt angle... and real-time pitch angle The total real-time platform tilt angle can be obtained by synthesis. Additionally, it can determine the real-time tilt axis direction of the platform. :

[0024]

[0025] like Figure 2 As shown, when the floating wind turbine platform is in its initial state and has not tilted, its body coordinate system... Axis and vertical direction When the axes coincide, and the floating wind turbine platform tilts, its body coordinate system... Axis and vertical direction The axes no longer coincide, and the angle between them is the total platform tilt angle. .

[0026] (2) Collect real-time actual power generation of wind turbines and the real-time wind speed at the height of the wind turbine hub and real-time wind direction These three parameters can be directly obtained using the wind turbine monitoring and data acquisition system.

[0027] To avoid the impact of frequent data fluctuations, one embodiment does not directly utilize each sampling time. Instead of directly performing subsequent calculations on the collected operating parameters, the floating wind power platform is analyzed at the current moment. Previously, the platform tilt angle, real-time platform tilt axis direction, real-time actual power generation of the wind turbine, real-time wind speed, and real-time wind direction at each sampling time within the most recent scheduled historical period were each averaged using a moving average method. Platform tilt axis direction Wind speed ,wind direction Actual power generation of wind turbines Then further calculations are performed. The duration of the predetermined historical period obtained by the moving average can be customized and modified remotely as needed, such as taking ten minutes.

[0028] Step 2, calculate the wind turbine power generation efficiency loss. And detect whether the efficiency loss threshold has been reached. .

[0029] Traditional load adjustment methods typically pre-set a fixed initial load adjustment angle. Load adjustment is triggered when the platform tilt reaches this angle. However, this approach is heavily reliant on empirically determined initial load adjustment angles. If the initial angle is too large, the platform cannot adjust its attitude promptly or respond quickly to changes in the external environment, leading to response delays, decreased wind turbine power generation efficiency and platform stability, and even safety concerns. Conversely, if the initial load adjustment angle is too small, the platform will frequently initiate load adjustment operations, which can lead to mechanical fatigue and increased energy consumption over time, increasing equipment maintenance costs.

[0030] To avoid the negative impact of a fixed initial load adjustment angle on wind turbine power generation efficiency and platform stability, this application determines whether to perform load adjustment operation based on the wind turbine power generation efficiency loss, and uses the real-time wind speed at the determined rotor hub height. Then, the theoretical power curve of the wind turbine is first used to determine the floating wind power platform at the current wind speed. The reference power below Then, combined with the actual power generation capacity of the wind turbine Calculate the wind turbine power generation efficiency loss under current conditions. :

[0031] Then determine the wind turbine power generation efficiency loss. Has the preset efficiency loss threshold been reached? .when This indicates that the load adjustment conditions are currently met, and step 3 is executed to trigger the load adjustment operation. At this time, load adjustment operations are not triggered, and the operating parameters of the floating wind power platform continue to be collected. Efficiency loss threshold. Settings can be customized and modified remotely as needed, such as retrieving... .

[0032] Step 3, when the wind turbine's power generation efficiency loss reaches the efficiency loss threshold When the load adjustment conditions are met, the current wind speed is determined based on a pre-calibrated multidimensional mapping database. and wind direction The target load adjustment angle is used to maximize the power generation of the wind turbine.

[0033] Existing traditional load adjustment methods generally pre-set a fixed target load adjustment angle and adjust the tilt angle to the target load adjustment angle in real time during load adjustment. However, this approach cannot guarantee that the platform attitude after load adjustment can maximize the wind turbine power generation efficiency under various operating conditions. Therefore, this application adaptively determines the target load adjustment angle with the goal of maximizing the wind turbine power generation.

[0034] The multidimensional mapping database used in this step is pre-calibrated. Considering that the optimal target load adjustment angle of the floating wind power platform is affected by multiple factors such as wind speed, vertical tilt angle of the wind turbine, and horizontal yaw angle, the pre-calibrated multidimensional mapping database includes different wind axis deflection angles. downwind speed -Platform tilt angle - Wind turbine power generation A multidimensional mapping database, wind axis deflection angle It is the direction of the platform tilt axis. With wind direction The included angle between and .

[0035] To calibrate this multidimensional mapping database, this application pre-constructs a numerical model of a floating wind power platform for numerical simulation calculations, obtaining the floating wind power platform at different wind speeds. Tilt angles of different platforms Different wind axis deflection angles The wind turbine power generation capacity Thus, the above-mentioned multidimensional mapping relationship database is obtained as a whole, including: A 3D model of the floating wind turbine platform and a steady-wind model are constructed. The 3D model of the floating wind turbine platform, following the platform's structure, includes the rotor (1), nacelle (2), tower (3), turbine platform foundation (4), and mooring system (5). Figure 2 As shown. The wind model used is a steady wind model, which generates a steady wind that acts on the three-dimensional model of the floating wind power platform and whose wind speed and direction are adjustable. The wind turbine 1 of the three-dimensional model of the floating wind power platform faces the direction of the oncoming wind.

The wind direction at the height of the wind turbine hub on the three-dimensional model of the floating wind power platform is affected by the steady wind model. relative to the platform tilt axis direction Wind axis deflection angle between To different values.

[0037] Adjusting the wind speed at the height of the wind turbine hub At that time, the wind speed variation range was within the range of that wind turbine. Within the range, that is, the wind speed at the height of the wind turbine hub. to Different values ​​within the range, It is the cut-in wind speed of the floating wind power platform. It is the cut-out wind speed of the floating wind power platform.

[0038] Adjusting the wind axis deflection angle At that time, the range of wind axis deflection angle variation is located in Within the range, that is, at the point where the height of the wind turbine hub is adjusted, the wind direction. relative to the platform tilt axis direction Wind axis deflection angle between to Different values ​​within the range.

[0039] Then the platform tilt angle Wind speed Wind axis deflection angle Numerical simulations were performed for each combination of values, and the motion degrees of freedom of the three-dimensional model of the floating wind turbine platform were constrained during the numerical calculations to maintain it at the platform's tilt angle. With the bottom fixed, the power generation capacity of the wind turbine is obtained. Based on the numerical simulation results under different combinations of values, different wind axis deflection angles can be calibrated. wind speed -Platform tilt angle - Wind turbine power generation A multidimensional mapping relationship database. For example, in one instance, wind axis deflection angle... A three-dimensional visualization diagram of the multidimensional mapping relationship of time is shown below. Figure 3 As shown, the calibrated database is stored in the active ballast system controller.

[0040] Then, when it is determined that the wind turbine power generation efficiency loss has reached the efficiency loss threshold... At that time, it is first based on different wind axis deflection angles downwind speed -Platform tilt angle - Wind turbine power generation A multidimensional mapping database is used to determine the wind speed at the current wind turbine hub height. and wind direction The direction of the target platform tilt axis when the wind turbine's power generation reaches its maximum value. Inclination angle with the target platform ,include: (1) Based on different wind axis deflection angles downwind speed -Platform tilt angle - Wind turbine power generation A multidimensional mapping database is used to determine the current wind speed. Different wind axis deflection angles Below are different platform tilt angles wind turbine power generation at that time .

[0041] The actual constructed multidimensional mapping database includes multiple finite wind axis deflection angles. The multidimensional mapping relationship below, and each wind axis deflection angle The multidimensional mapping relationship also includes multiple - - Three-dimensional discrete data points, such as Figure 3 As shown. This results in the current wind speed At each wind axis deflection angle The corresponding existing data points may not necessarily exist directly, so a linear interpolation algorithm is used to determine the wind axis deflection angle. downwind speed -Platform tilt angle - Wind turbine power generation Data interpolation is performed on discrete data points in a multidimensional mapping relationship to determine the current wind speed. At the current wind axis deflection angle Below are different platform tilt angles wind turbine power generation at that time .
