[0045] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0046] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0047] The main solution of the embodiment of the present application is: obtaining meteorological information of the environment in which the wind turbine is located; if the meteorological information is a preset meteorological condition, obtaining the current wind turbine operating data of the wind turbine and the current wind conditions of the environment in which the wind turbine is located; inputting the current wind turbine operating data and the current wind conditions into the distance prediction model to obtain the clearance distance value output by the distance prediction model; the distance prediction model is trained by training samples under normal meteorological conditions; the training samples include wind turbine operating data features and corresponding wind condition features, and the labels of the training samples are the actual clearance distance values ​​measured under normal meteorological conditions; based on the clearance distance value, the operating parameters of the wind turbine are adjusted.

[0048] In this embodiment, for ease of description, the following description is made with the wind turbine generator control device as the execution subject.

[0049] During the operation of a wind turbine, lidar technology can be used to monitor the clearance distance value of the wind turbine, and to adjust operating parameters such as blade angle according to the clearance distance value to ensure the safe and stable operation of the wind turbine.

[0050] At present, there are three main ways to measure the clearance distance of wind turbines:

[0051] 1. Monitoring the clearance distance value through laser radar: A laser radar is installed at the bottom of the nacelle. The laser radar can scan the blades and tower to obtain the point cloud data of the blades and the point cloud data of the tower. The laser radar transmits the point cloud data of the blades and the point cloud data of the tower to the wind turbine control device. The wind turbine control device filters and processes the point cloud data of the blades and the tower to obtain the filtered point cloud data of the blades and the filtered point cloud data of the tower. Finally, the minimum distance value between the tower and the blade tip is calculated through the detection algorithm based on the filtered point cloud data of the blades and the filtered point cloud data of the tower, and the minimum distance value is used as the clearance distance value;

[0052] 2. Calculate the clearance distance value through the three-line laser clearance radar: The three-line laser clearance radar determines the clearance distance value range of the wind turbine by emitting three beams of light;

[0053] 3. Calculate the clearance distance value through the camera video: Use the camera to obtain the image of the wind turbine blade, capture the blade outline based on the image processing algorithm, and calculate the distance between the tower and the blade based on the information of the blade point.

[0054] However, when abnormal weather occurs, the clearance distance value calculated by the above method will be interfered with by external factors such as rain, snow, and haze. As a result, when adjusting operating parameters such as blade angle according to the clearance distance value, the adjustment of operating parameters may not be consistent with the actual operating conditions of the wind turbine under abnormal weather conditions, affecting the control effect.

[0055] The present application provides a solution. When the meteorological information of the environment in which the wind turbine generator set is located is a preset meteorological condition, the current wind turbine generator set operating data and the current wind conditions of the wind turbine generator set are input into a distance prediction model to obtain a clearance distance value output by the distance prediction model, and the clearance distance value is used to adjust the operating parameters of the wind turbine generator set. Compared with the related art, which relies solely on the clearance distance value obtained by laser radar measurement to adjust the operating parameters of the wind turbine generator set, the present application combines laser radar with a neural network model. That is, under normal meteorological conditions, the measured clearance distance measured by the laser radar, the wind turbine generator set operating data and the corresponding wind condition characteristics are used as training samples to train a distance prediction model. Under preset meteorological conditions, the distance prediction model is used to obtain a predicted clearance distance value. This can reduce the impact of external factors such as rain, snow, fog and haze on the clearance distance value. As a result, when adjusting operating parameters such as blade angle according to the predicted clearance distance value, it can avoid the situation where the adjustment of operating parameters is inconsistent with the actual operating conditions of the wind turbine generator set under abnormal weather conditions, thereby improving the control effect of the wind turbine generator set.

[0056] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, a wind turbine generator control device, etc. The following describes this embodiment and the following embodiments using a wind turbine generator control device as an example.

[0057] Based on this, the embodiment of the present application provides a wind turbine generator control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the wind turbine generator control method of the present application.

[0058] In this embodiment, the wind turbine generator control method includes steps S10 to S40:

[0059] Step S10: Acquire meteorological information of the environment in which the wind turbine generator set is located.

[0060] Specifically, the wind turbine control device may periodically send a weather information acquisition request to a weather station or weather service provider at a preset time interval. After receiving the weather information acquisition request, the weather station or weather service provider sends the weather information of the wind turbine environment to the wind turbine control device.

[0061] Step S20: If the meteorological information is a preset meteorological condition, the current wind turbine operating data of the wind turbine and the current wind conditions of the environment in which the wind turbine is located are obtained.

[0062] In this embodiment, the wind turbine operating data can be stored locally in the wind turbine control device. When executing step S20, the wind turbine control device can directly read the current wind turbine operating data of the wind turbine from the local device. The current wind turbine operating data includes the current impeller speed, the current pitch angle, and the current blade deformation data; and / or the preset meteorological conditions are rainy, snowy, or foggy. The current blade deformation data is the distance value between the ranging point and the reference point measured by the ranging sensor. The ranging point is the intersection of the ranging line of sight of the ranging sensor and the blade contour line. The ranging sensor is fixedly arranged at the center position of the blade root, and when the blade is not deformed, the ranging line of sight passes through the tip of the blade.

[0063] The current wind condition may be the current wind speed and the current wind direction of the environment in which the wind turbine generator set is located. The reference point may be the center point of the blade root, or the reference point may be the starting point of the ranging line of sight of the ranging sensor.

[0064] Specifically, refer to Figure 2 As shown, Figure 2 The distance sensor 10 is fixed at the center of the blade root when the blade is not deformed. When the blade is not deformed, the distance measurement line of sight passes through the tip of the blade. The length measured by the distance sensor is D1. When the blade is deformed, the parameter Figure 3 As shown, Figure 3 Figure 1 is a schematic diagram of a blade deformation condition. When a blade deforms, the ranging sensor's sightline intersects the blade's outline at point A, the ranging point. The distance between the ranging point and the reference point is used as the current blade deformation data, or D2.

[0065] Step S30 , inputting the current wind turbine operating data and the current wind conditions into the distance prediction model to obtain the clearance distance value output by the distance prediction model.

[0066] The distance prediction model is trained using training samples under normal meteorological conditions; the training samples include wind turbine operating data features and corresponding wind condition features, and the labels of the training samples are the actual clearance distance values ​​measured under normal meteorological conditions.

[0067] For example, the radial basis function neural network algorithm can be used to construct an initial prediction model, and the Gaussian function can be used as the radial basis function neural network transfer function. The wind condition characteristics and the operating data characteristics of the wind turbine generator set can be used as the input parameters of the model. The measured clearance distance value can be used as the output parameter to train the initial prediction model to obtain a distance prediction model.

[0068] In this embodiment, the clearance distance value can be the distance between the blade tip and the tower when the blade tip is at the lowest point during operation. Figure 4 As shown, Figure 4 This is a simplified schematic diagram of a wind turbine. The end of tower 1, away from the ground, is connected to nacelle 2, which is then connected to hub 3. Blades 4 are connected to hub 3. When the blade tip is at its lowest point, the distance D between the blade tip and the tower is the clearance distance. When the clearance distance is greater than the minimum distance between the blade tip and the tower, the blades will not contact the tower during rotation, thus preventing potential collision and structural damage.

[0069] When the current wind turbine operating data and the current wind conditions are input into the distance prediction model to obtain the clearance distance value output by the distance prediction model, in order to obtain a more accurate clearance distance value and reduce the error between the predicted clearance distance value and the actual clearance distance value, further, as an optional implementation, before step S30, the following is further included:

[0070] Step S28: Under normal meteorological conditions, obtain a point cloud data set collected by the lidar.

[0071] The point cloud dataset includes a first point cloud dataset of the blade and a second point cloud dataset of the tower.

[0072] Step S29: determining the measured clearance distance value based on the point cloud data set.

[0073] In this embodiment, the laser radar 5 can be fixedly arranged directly below the wheel hub 3, such as Figure 5 As shown, Figure 5 Schematic diagram of the location of the lidar.

[0074] Specifically, the laser radar can communicate with the wind turbine control device. Under normal meteorological conditions, the laser radar can periodically collect the first point cloud data set of the blades and the second point cloud data set of the tower at a preset interval, and send the collected first point cloud data set and second point cloud data set to the wind turbine control device.

[0075] It should be noted that after receiving the point cloud dataset, the wind turbine control device can determine the measured clearance distance value based on the point cloud dataset. When calculating the measured clearance distance value based on the point cloud dataset, in order to improve the quality of the point cloud data and calculation efficiency, further, as an optional implementation, step S29 specifically includes:

[0076] Step S291 : pre-process the first point cloud dataset to obtain a first target point cloud dataset.

[0077] Step S292: pre-process the second point cloud dataset to obtain a second target point cloud dataset.

[0078] Step S293: construct a blade model using the first target point cloud data set, and construct a tower model using the second target point cloud data set.

[0079] Step S294: determine the first point cloud coordinates of the blade tip point of the blade model.

[0080] Step S295: Determine the second point cloud coordinates from the tower model.

[0081] The second point cloud coordinates are the point cloud coordinates that are at the same height as the first point cloud coordinates and have the shortest straight-line distance.

[0082] Step S296: Determine the measured clearance distance value using the first point cloud coordinates and the second point cloud coordinates.

[0083] Specifically, after receiving the first point cloud data set and the second point cloud data set sent by the laser radar, the wind turbine control device can perform pre-processing such as filtering and screening on the first point cloud data set and the second point cloud data set respectively to obtain the first target point cloud data set and the second target point cloud data set and use the first target point cloud data set to construct a blade model, and use the second target point cloud data set to construct a tower model. After obtaining the blade model and the tower model, the tip point of the blade and the first point cloud coordinates of the tip point can be determined from the blade model. After determining the first point cloud coordinates, the second point cloud coordinates can be determined from the tower model based on the first point cloud coordinates, that is, the point cloud coordinates that are at the same height as the first point cloud coordinates and have the shortest straight-line distance. After obtaining the first point cloud coordinates and the second point cloud coordinates, the measured clearance distance value can be calculated based on the first point cloud coordinates and the second point cloud coordinates.

[0084] In this embodiment, after obtaining the point cloud dataset, the first point cloud dataset and the second point cloud dataset are preprocessed to remove noise, errors and unnecessary data points, so that subsequent modeling is more accurate and efficient, thereby obtaining more accurate measured clearance distance values, and then when the measured clearance distance values ​​are used as training sample labels for model training, the distance prediction model obtained by training is more accurate.

[0085] Step S40: adjusting the operating parameters of the wind turbine generator set based on the clearance distance value.

[0086] Specifically, when adjusting the operating parameters of the wind turbine based on the clearance distance value, in order to ensure that the wind turbine does not interfere with surrounding objects during operation and avoid potential collisions and damage, further, as an optional implementation method, step S40 can be adaptively changed to: if the clearance distance is less than a preset threshold, the blade angle is increased, that is, by changing the aerodynamic characteristics of the blade, so that the blade with the increased blade angle can generate less lift at the same speed, thereby increasing the distance between the tip of the blade and the tower and reducing the risk of interference.

[0087] In this embodiment, when the meteorological information of the environment in which the wind turbine generator set is located is a preset meteorological condition, the current wind turbine generator set operating data and the current wind conditions of the wind turbine generator set are input into a distance prediction model to obtain a clearance distance value output by the distance prediction model, and the clearance distance value is used to adjust the operating parameters of the wind turbine generator set. Compared to the related art that solely relies on the clearance distance value obtained by laser radar measurement to adjust the operating parameters of the wind turbine generator set, this embodiment combines laser radar with a neural network model. That is, under normal meteorological conditions, the measured clearance distance measured by the laser radar, the wind turbine generator set operating data, and the corresponding wind condition characteristics are used as training samples to train a distance prediction model. Under the preset meteorological conditions, the distance prediction model is used to obtain a predicted clearance distance value. This can reduce the impact of external factors such as rain, snow, and haze on the clearance distance value. Furthermore, when adjusting operating parameters such as the blade angle based on the predicted clearance distance value, it can avoid the situation where the adjustment of the operating parameters is inconsistent with the actual operating conditions of the wind turbine generator set under abnormal weather conditions, thereby improving the control effect of the wind turbine generator set.

[0088] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the wind turbine control method of the present application.
