Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, specifically to a method and system for dynamic compensation and correction of wind tower center coordinates based on BeiDou positioning. Background Technology

[0002] Traditional methods for monitoring wind turbine foundations primarily rely on technologies such as laser ranging, GPS measurement, and closed-loop leveling. However, these methods suffer from drawbacks in practical applications, including high cost, limited accuracy, and complex installation. Especially in complex terrain and harsh weather conditions, the monitoring results of these methods are often unsatisfactory.

[0003] The BeiDou Navigation Satellite System, independently developed by my country, boasts significant advantages such as high precision, all-weather operation, all-time coverage, and global reach. In recent years, with the continuous development and improvement of BeiDou technology, its application in wind power generation has become increasingly widespread. Utilizing BeiDou's high-precision positioning technology for real-time monitoring of wind turbine foundations has become a viable solution.

[0004] However, relying solely on BeiDou positioning technology cannot completely solve all the problems in wind turbine foundation safety monitoring. Because wind turbine towers are affected by various factors such as wind load and temperature during operation, their center coordinates will shift to some extent. Therefore, current technologies relying solely on BeiDou positioning technology for pre-construction monitoring of wind turbine foundations contain errors.

[0005] In summary, there is an urgent need for a convenient and highly accurate method and system for monitoring wind turbine towers to solve the problems existing in the current technology. Summary of the Invention

[0051] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0052] The accompanying drawings, which form part of this application, are used to provide a further understanding of the invention. The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an undue limitation of the invention. In the drawings:

[0054] The components include: 1. Beidou receiver; 2. Data acquisition module; 3. Data processing module; 4. Dynamic compensation and correction module; 5. Display module; and 6. Wind tower. Detailed Implementation

[0055] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0056] Example:

[0057] See Figure 1 A dynamic compensation and correction system for the center coordinates of a wind tower, comprising a Beidou receiver 1, a data acquisition module 2, a data processing module 3, a dynamic compensation and correction module 4, and a display module 5;

[0058] The Beidou receiver 1 is installed on the wind tower and is used to receive positioning signals sent by Beidou satellites and calculate the position information of the center of the top of the wind tower.

[0059] The data acquisition module 2 is used to collect attitude information and environmental information of the top of the wind tower. In this embodiment, preferably, the data acquisition module 2 includes an attitude angle sensor and a micro-meteorological sensor. The attitude angle sensor is used to collect attitude information of the top of the wind tower, including pitch angle, roll angle and heading angle. The micro-meteorological sensor is used to collect environmental information, including wind speed, wind direction, temperature and humidity.

[0060] Both the Beidou receiver 1 and the data acquisition module 2 are connected to the data processing module 3. The data processing module 3 is used to fuse the position information calculated by the Beidou receiver and the attitude information acquired by the data acquisition module. After geocentric-ground coordinate transformation, a preliminary estimate of the wind tower center coordinates is obtained.

[0061] The dynamic compensation and correction module 4 is connected to the data processing module 3. The dynamic compensation and correction module 4 is equipped with a wind tower motion model, which is used to dynamically compensate and correct the preliminary estimated value of the wind tower center coordinates based on the wind tower's operating status and environmental information (i.e., external environmental factors), so as to obtain the dynamically compensated and corrected wind tower center coordinate values.

[0062] The display module 5 is connected to the dynamic compensation and correction module 4. The display module 5 is used to visualize the center coordinates of the wind turbine during dynamic compensation and correction. Operators can monitor the operating status and deformation of the wind turbine in real time by observing the data and information on the display module.

[0063] The above-mentioned dynamic compensation and correction system for the wind tower center coordinates is applied for dynamic compensation and correction. The specific method includes the following steps:

[0064] Step 1: Monitor the top position and attitude information of the wind turbine in real time using the Beidou receiver and data acquisition module. Specifically, start the Beidou receiver 1 and data acquisition module 2 to receive the positioning signal sent by the Beidou satellite and collect the attitude information of the top of the wind turbine and external environmental factors.

[0065] The received positioning signal and the collected attitude information are input into the data processing module 3 for fusion processing to obtain a preliminary estimate of the wind tower center coordinates.

[0066] Step 2: Based on the top position and attitude information of the wind tower obtained in Step 1, and combined with the wind tower motion model, perform dynamic compensation and correction on the preliminary estimated value of the wind tower center coordinates, and output the dynamically compensated and corrected wind tower center coordinate values.

[0067] Step 3: Output the dynamic compensation and correction wind turbine center coordinates (i.e., the precise wind turbine center coordinates) to display module 5 for visualization. Operators can monitor the wind turbine's operating status and deformation in real time by observing the data and information on the display module, and make corresponding adjustments and optimizations as needed.

[0068] The core of the dynamic compensation and correction module 4 lies in its ability to perform precise dynamic compensation and correction of the wind tower center coordinates based on real-time monitoring of the wind tower's top center position and attitude information, as well as the wind tower's motion patterns and external environmental factors. The specific implementation steps are as follows:

[0069] I. Data Preprocessing:

[0070] The system receives real-time location information (longitude, latitude, and altitude) of the wind turbine top from Beidou receiver 1; and receives wind turbine top attitude information and external environmental information from data acquisition module 2. This data undergoes preprocessing, including data filtering, outlier detection and processing, to ensure accuracy and reliability.

[0071] II. Establishing a wind tower motion model:

[0072] The method for obtaining the wind turbine motion model is as follows:

[0073] A wind tower motion model is established based on the wind tower's structural parameters (such as height, diameter, and material properties) and environmental information (such as wind speed, wind direction, and temperature). This model describes the deformation and displacement of the wind tower under the influence of external factors such as wind load and temperature. The aforementioned wind tower motion model includes:

[0074] ① Kinematic model under wind load:

[0075] Under wind load, the top of the wind tower will experience horizontal displacement. To simplify the model, the wind tower can be considered as a cantilever beam structure, and relevant formulas from structural mechanics can be applied to calculate the displacement, as follows:

[0076] Calculation of horizontal displacement Δx:

[0077] The formula for calculating the horizontal displacement Δx is as follows:

[0078]

[0079] Where: P is the pressure generated by the wind (i.e., wind load), which can be calculated based on parameters such as wind speed, wind pressure coefficient, and tower windward area using existing technology; L is the tower height; E is the elastic modulus of the tower material; I is the moment of inertia of the tower section. For cylindrical towers, the moment of inertia I of the tower section is calculated using the following formula: Where D is the diameter of the tower section;

[0080] Calculation of torsional displacement θ:

[0081] Wind loads can also cause torsional displacement of the wind turbine tower. The formula for calculating the torsional displacement θ is relatively complex, typically requiring consideration of factors such as the torque effect of the wind load and the torsional stiffness of the tower. In this embodiment, the following formula is used for calculation:

[0082]

[0083] Where: T is the torque, which can be calculated based on wind load and tower cross-sectional shape using existing technology; G is the shear modulus of the tower material; J is the polar moment of inertia of the tower cross-section. For cylindrical towers, the polar moment of inertia J of the tower cross-section is calculated using the following formula:

[0084] ② Motion model under temperature change:

[0085] Temperature changes cause expansion and contraction deformation of the tower. To calculate this deformation, the thermal expansion formula can be applied, and the expansion and contraction deformation ΔL is calculated using the following formula:

[0086] ΔL=αLΔT;

[0087] Where: α is the coefficient of thermal expansion of the tower material; ΔT is the temperature change.

[0088] III. Real-time monitoring data fusion:

[0089] Obtaining the preliminary estimate of the wind tower center coordinates includes the following steps:

[0090] The geocentric coordinates are calculated using the following formula:

[0091]

[0092] Where: lon is longitude information, lat is latitude information, alt is altitude information, f is polar flattening, and N is the radius of curvature of the reference ellipsoid;

[0093] Converting the ECEF coordinates to the Northeast-Eastern Sky (ENU) coordinate system yields a preliminary estimate of the wind tower center coordinates. The conversion formula is as follows:

[0094] The origin of the ECEF coordinate system is the Earth's center of mass. The x-axis extends through the intersection of the Prime Meridian and the equator, the z-axis extends through the North Pole (i.e., coincides with the Earth's rotation axis), and the y-axis completes the right-hand coordinate system, passing through the equator and 90 degrees longitude.

[0095] The origin is P0(x0, y0, z0), the target point is P(x, y, z), the coordinates in the northeast-sky coordinate system with P0 as the origin are (X0, Y0, Z0), and the coordinates in the latitude-longitude-height coordinate system are LLA0(lon0, lat0, alt0), where S is the following orthogonal matrix:

[0096]

[0097] IV. Dynamic Compensation and Correction Calculation:

[0098] Based on the wind tower motion model and real-time monitoring data, the displacement and deformation of the wind tower top are calculated. Taking into account the structural characteristics of the wind tower and external environmental factors, dynamic compensation and correction are performed on the wind tower center coordinates.

[0099] The formula used for dynamic compensation and correction of the preliminary estimated coordinates of the wind turbine center is as follows:

[0100]

[0101] Where: X c Y c Z c X0 represents the wind tower center coordinates after dynamic compensation and correction; X0, Y0, and Z0 are the preliminary estimates of the wind tower center coordinates; ΔX model ΔY model ΔZ model ΔX is the displacement calculated based on the wind tower motion model. env ΔY env ΔZ env This is the displacement calculated based on environmental information.

[0102] In this embodiment, the preferred displacement calculated based on the wind tower motion model is as follows:

[0103] For the displacement calculation of the model, a simplified model of the wind tower as a cantilever beam structure is considered. Under wind load, the top of the wind tower will not only experience horizontal displacement (in the X or Y direction, depending on the wind direction), but may also experience a slight torsional effect leading to Z-direction displacement (usually small, but considered for integrity). However, for most cases, the main focus is on horizontal displacement.

[0104] Displacement in the X direction (assuming wind load is along the X direction):

[0105] Wherein: F x H represents the wind load in the x-direction, and H represents the height of the wind tower.

[0106] Y-direction displacement: If there is no wind load in the Y direction, then ΔY model =0. If so, use the same formula but change F. x Replace with F y .

[0107] Z-direction displacement: For cantilever beam structures, under pure wind load, the Z-direction displacement is usually very small and mainly caused by torsional effects. For simplicity, we can assume ΔZ model =0, unless there is a specific torsional analysis.

[0108] In this embodiment, the preferred displacement calculated based on environmental information is as follows:

[0109] Environmental displacement is mainly considered in terms of temperature effect. Generally speaking, the material of the wind tower expands thermally as the temperature rises, with a coefficient of thermal expansion of α and a temperature change of ΔT. Since the temperature is uniform, it usually does not cause displacement in the X or Y direction, but it will cause expansion and contraction in the Z direction.

[0110] Z-direction displacement:

[0111] ΔZ env =α*H*ΔT;

[0112] X / Y direction displacement: Since the temperature is uniform, it will not cause displacement in the X or Y direction, so ΔX env =0 and ΔY env =0.

[0113] V. Results Output and Visualization:

[0114] The dynamically compensated and corrected center coordinates of the wind turbine are output to display module 5 for visualization. Operators can monitor the wind turbine's operating status and deformation in real time by observing the data and information on the display module.

[0116] First, it improves the accuracy and reliability of wind turbine foundation safety monitoring: By adopting BeiDou high-precision positioning technology and dynamic compensation and correction algorithms, this invention can realize real-time monitoring and precise adjustment of the wind tower center coordinates, effectively improving the accuracy and reliability of wind turbine foundation safety monitoring.

[0117] Secondly, it reduces monitoring costs: Compared with traditional monitoring methods, this invention does not require the installation of a large number of sensors and measuring equipment on the wind turbine, thus reducing monitoring costs.

[0118] Third, it enhances the adaptability and flexibility of the system: the invention can be dynamically adjusted and optimized according to the structural characteristics and operating environment of the wind tower, thus enhancing the adaptability and flexibility of the system.
