Description

Technical Field

[0001] This invention relates to the field of tower displacement detection technology, and in particular to a method, apparatus, equipment and storage medium for detecting tower sway displacement. Background Technology

[0002] Currently, wind turbine towers are over 100 meters high. Under long-term cyclic loads or extreme loads, they are prone to excessive swaying, leading to instability and even the risk of direct tower collapse. Damage to the tower structure also affects the sway amplitude. Therefore, detecting the sway displacement of wind turbine towers is necessary. However, current methods of calculating displacement by installing tilt sensors at specific locations on the tower only calculate the static displacement. When the tower is affected by gusts of wind, the resulting dynamic sway may be lost. Furthermore, the tilt sensors have a low sampling rate and relatively poor real-time performance.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Currently, wind turbine towers are over 100 meters high. Under long-term cyclic loads or extreme loads, they are prone to excessive swaying, leading to instability and even the risk of direct tower collapse. Damage to the tower structure also affects the sway amplitude. Therefore, detecting the sway displacement of wind turbine towers is necessary. However, current methods of calculating displacement by installing tilt sensors at specific locations on the tower only calculate the static displacement. When the tower is affected by gusts, the resulting dynamic sway may be lost. Furthermore, the tilt sensors have a low sampling rate and relatively poor real-time performance. To address this, this application provides a tower sway displacement detection scheme that avoids calculating displacement by installing tilt sensors, preventing the loss of dynamic sway data and improving the accuracy of tower sway displacement detection.

[0047] This invention discloses a method for detecting tower sway displacement. See [link to relevant documentation]. Figure 1 As shown, the method includes:

[0048] Step S11: Obtain the lateral acceleration component and radial acceleration component of the tower using a dual-coordinate vibration accelerometer.

[0049] It should be noted that wind turbine towers are divided into rigid towers and flexible towers. Rigid towers are primarily made of steel, while flexible towers are mostly composite material towers. Composite material towers are the preferred material structure due to their lightweight, low cost, and ability to reduce wind vibration loads. Therefore, flexible towers are currently the main structural form of wind turbine towers. However, because flexible towers have low stiffness, they will bend and deform under wind loads, such as… Figure 2 As shown, under wind load, the tower will deviate from the neutral position OO1 and be in a stable position OO2. At this time, there is a static displacement O1O2. The tower will generate a slight dynamic sway OO3 around the equilibrium position OO2, and there is also a dynamic displacement O2O3. Therefore, the actual swaying displacement of the tower is the sum of the above static displacement and the above dynamic displacement.

[0050] In this embodiment, the lateral and radial acceleration components of the tower are acquired using a dual-coordinate vibration accelerometer. It is understood that no additional tilt sensor is needed; instead, the lateral and radial acceleration components of the tower are acquired directly from the dual-coordinate vibration accelerometer. For example, the lateral acceleration component 'a' is acquired using a dual-coordinate vibration accelerometer mounted on the top of the tower. x and radial acceleration component a y It should be noted that the dual-coordinate vibration acceleration sensor can be installed at the top of the tower and / or in the middle of the tower.

[0051] Step S12: Determine the actual offset acceleration of the tower based on the lateral acceleration component and the radial acceleration component.

[0052] In this embodiment, after acquiring the lateral acceleration component and radial acceleration component of the tower using a dual-coordinate vibration acceleration sensor, the actual offset acceleration of the tower is determined based on the lateral velocity component and the radial acceleration component. For example, when the lateral acceleration component is a... x The radial acceleration component is a y Then the actual offset acceleration 'a' of the synthesized tower is

[0053] Step S13: Calculate the static acceleration component and dynamic acceleration component corresponding to the actual offset acceleration.

[0054] In this embodiment, after determining the actual offset acceleration of the tower based on the lateral acceleration component and the radial acceleration component, the static acceleration component and dynamic acceleration component corresponding to the actual offset acceleration can be calculated. That is, by averaging all the actual offset accelerations, the calculated mean value is determined as the static acceleration component corresponding to the actual offset acceleration, and the difference between the actual offset acceleration and the mean value is determined as the dynamic acceleration component corresponding to the actual offset acceleration. For example, the static acceleration component of the actual offset acceleration 'a' is a0, and the dynamic acceleration component is a1.

[0055] Step S14: Calculate the static displacement of the tower based on the static acceleration component, and calculate the target dynamic displacement of the tower based on the dynamic acceleration component.

[0056] In this embodiment, after calculating the static acceleration component and dynamic acceleration component corresponding to the actual offset acceleration, the static displacement of the tower can be calculated based on the static acceleration component, and the target dynamic displacement of the tower can be calculated based on the dynamic acceleration component. That is, the lateral and radial acceleration components of the tower are collected in real time by a dual-coordinate vibration sensor, and then acceleration data is synthesized based on the lateral and radial acceleration components. In other words, the static and dynamic displacements of the tower are calculated based on the target acceleration data under high sampling conditions, while also taking into account the need for monitoring the vibration state of the tower. Calculating the target dynamic displacement of the tower based on the dynamic acceleration component can include: calculating the dynamic displacement of the tower at each moment based on the dynamic acceleration component; and determining the target dynamic displacement of the tower within a preset time range based on the dynamic displacement at each moment. It can be understood that the dynamic displacement that meets the preset conditions is selected from the dynamic displacements corresponding to the tower at each moment as the target dynamic displacement. For example, the dynamic displacement with the largest value among the dynamic displacements of the tower at each time moment is determined as the target dynamic displacement of the tower within a preset time range.

[0057] Step S15: Determine the actual sway displacement of the tower based on the static displacement and the target dynamic displacement.

[0058] In this embodiment, after determining the static displacement and the target dynamic displacement of the tower, the actual swaying displacement of the tower can be determined based on the static displacement and the target dynamic displacement. It can be understood that the actual swaying displacement of the tower is obtained by summing the static displacement and the target dynamic displacement. For example, if the static displacement of the tower is calculated as y0 based on the static acceleration component, and the target dynamic displacement of the tower is calculated as y1 based on the dynamic acceleration component, then the actual swaying displacement of the tower is y = y0 + y1.

[0059] As can be seen, in this embodiment of the application, by acquiring the corresponding acceleration components through a dual-coordinate vibration sensor installed at the top of the tower, the static displacement and dynamic displacement of the tower are calculated based on the acceleration data synthesized from the acceleration components, thereby determining the actual swaying displacement of the tower. This avoids calculating the swaying displacement of the tower by measuring the tilt angle through an inclined sensor and prevents the loss of dynamic swaying data, thus reflecting the actual swaying displacement of the tower more in real time and more accurately.

[0060] For example, by installing acceleration sensors at the top and middle of the tower, the change in sway displacement across the entire rotational speed range can be observed. Figure 3 As shown, the sway displacement of the tower is consistent with the actual displacement.

[0061] See Figure 4 As shown, this embodiment of the invention discloses a specific method for detecting tower sway displacement. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution.

[0062] Step S21: Obtain the lateral acceleration component and radial acceleration component of the tower using a dual-coordinate vibration accelerometer.

[0063] Step S22: Determine the actual offset acceleration of the tower based on the lateral acceleration component and the radial acceleration component.

[0064] Step S23: Calculate the static acceleration component and dynamic acceleration component corresponding to the actual offset acceleration.

[0065] Step S24: Determine the static offset acceleration corresponding to the tower based on the value corresponding to the DC operating point of the dual-coordinate vibration acceleration sensor and the static acceleration component.

[0066] In this embodiment, after determining the static acceleration component corresponding to the actual offset acceleration, the static offset acceleration corresponding to the tower is determined based on the value corresponding to the DC operating point of the dual-coordinate vibration accelerometer and the static acceleration component. It can be understood that the difference between the value corresponding to the DC operating point of the dual-coordinate vibration accelerometer and the static acceleration component is determined as the static offset acceleration corresponding to the tower. For example, if the static acceleration component corresponding to the actual offset acceleration is a0, and the measured DC operating point of the sensor is a... z Then the static offset acceleration corresponding to the tower is a. j =a0-a z .

[0067] Step S25: Determine the static tilt angle of the tower based on the static offset acceleration of the tower.

[0068] In this embodiment, after determining the static offset acceleration corresponding to the tower based on the value corresponding to the DC operating point of the dual-coordinate vibration accelerometer and the static acceleration component, the static tilt angle corresponding to the tower is determined based on the static offset acceleration. That is, the static tilt angle corresponding to the tower can be determined based on the static offset acceleration using the trigonometric relationship of the tower tilt. For example, the static tilt angle corresponding to the tower is θ. In other words, this embodiment avoids measuring the tilt angle by installing a tilt sensor at a specific position on the tower. Instead, it collects the lateral and radial acceleration components of the tower in real time by installing a dual-coordinate vibration sensor, and indirectly calculates the tilt angle of the tower by combining the acceleration data based on the lateral and radial accelerations.

[0069] Step S26: Calculate the static displacement of the tower using the preset static displacement calculation formula and the static tilt angle.

[0070] It should be noted that by approximating the tower and foundation support as a cantilever beam structure, the relationship between deflection and rotation angle at different cross-sectional heights x, i.e., the relationship between sway displacement y and tilt angle θ, can be obtained based on the deflection curve equation:

[0071] θ(x)≈tanθ(x)=y′(x);

[0072]

[0073] Where M(x) represents the bending moment, EI represents the bending moment stiffness (a constant), q represents the force acting on the tower (a variable), and L represents the tower height (a constant). Based on the above, we know that: A first integration yields the tilt angle θ:

[0074] The deflection can be obtained by double integration:

[0075]

[0076] According to the boundary conditions, when x = 0, θ = 0, y = 0;

[0077] Therefore, the tilt angle and displacement at different height positions are:

[0078]

[0079]

[0080] In this embodiment, after calculating the tilt angle of the tower, the static displacement of the tower is calculated using a preset static displacement calculation formula and the static tilt angle. That is, the force q acting on the tower is determined by using the calculated tilt angle, and then this force q is substituted into the formula. The static displacement y0 of the tower can then be calculated.

[0081] Step S27: Calculate the dynamic displacement of the tower at each moment based on the dynamic acceleration components using the multiple integration method.

[0082] In this embodiment, the dynamic acceleration component corresponding to the target acceleration is calculated by using the multiple integration method to calculate the dynamic displacement of the tower at each moment based on the dynamic acceleration component.

[0083] Step S28: The dynamic displacement with the largest value is determined as the target dynamic displacement of the tower within a preset time range.

[0084] In this embodiment, after calculating the dynamic displacement of the tower at each moment, the dynamic displacement with the largest value is determined as the target dynamic displacement of the tower within a preset time range.

[0085] Step S29: Determine the actual sway displacement of the tower based on the static displacement and the target dynamic displacement.

[0086] For details regarding steps S21 to S23 and S29, please refer to the corresponding content disclosed in the foregoing embodiments, which will not be repeated here.

[0087] As can be seen, in this embodiment of the application, by acquiring the corresponding acceleration components through a dual-coordinate vibration sensor installed at the top of the tower, the static displacement and dynamic displacement of the tower are calculated based on the acceleration data synthesized from the acceleration components, thereby determining the actual swaying displacement of the tower. This avoids calculating the swaying displacement of the tower by measuring the tilt angle through an inclined sensor and prevents the loss of dynamic swaying data, thus reflecting the actual swaying displacement of the tower more in real time and more accurately.

[0088] For example, such as Figure 5 As shown, by installing a dual-coordinate vibration acceleration sensor at the top of the tower, the DC operating point a of the sensor is measured. z At the same time, the acceleration component a is obtained. x a y According to the acceleration component a x a y Actual offset acceleration of the synthesis tower Calculate the static acceleration component a0 and the dynamic acceleration component a1 of the actual offset acceleration 'a' of the tower, i.e., the DC component a0 and the dynamic component a1. This is based on the static acceleration component a0 and the DC operating point a of the sensor. z Calculate the static acceleration a of the tower. j =a0-a zTherefore, the static tilt angle θ of the tower can be obtained. Then, based on the preset static displacement calculation formula and the static tilt angle, the static displacement y0 of the tower is obtained. The dynamic displacement of the tower at each moment is calculated by the multiple integration method according to the dynamic acceleration component a1. The dynamic displacement with the largest value is determined as the target dynamic displacement y1 of the tower within the preset time range. Then, the actual displacement of the tower is y = y0 + y1.

[0089] Accordingly, this application also discloses a tower sway displacement detection device, see [link to relevant documentation]. Figure 6 As shown, the device includes:

[0096] As can be seen from the above, in this embodiment of the application, the corresponding acceleration components are obtained by a dual-coordinate vibration sensor installed at the top of the tower. The static displacement and dynamic displacement of the tower are calculated based on the acceleration data synthesized from the acceleration components, thereby determining the actual swaying displacement of the tower.
