Fig. 1 is a schematic side view of an example of a wind turbine generator system according to an embodiment of the present disclosure. As shown in fig. 1, the wind turbine includes a blade 11, a nacelle 12, and a tower 13. The tower clearance of the wind generating set refers to the distance from the blade tip of the blade 11 to the surface of the tower 13 during the rotation of the impeller. D1 in FIG. 1 is the tower clearance of the wind turbine. During rotation of the blades 11, the tower 13 may be reached due to too small a clearance of the tower, i.e. a blade sweep occurs. Once a blade sweep event occurs, the blade 11 needs to be replaced.

The wind generating set tower clearance monitoring system and the wind generating set are explained in sequence below.
The application provides a wind generating set pylon headroom monitoring system. FIG. 2 is a schematic structural diagram of an embodiment of a tower clearance monitoring system of a wind generating set. FIG. 3 is a schematic structural diagram of another embodiment of a tower clearance monitoring system of a wind generating set provided by the present application. As shown in FIGS. 2 and 3, the wind generating set tower clearance monitoring system can comprise a laser radar 21 and an industrial personal computer 22.
The laser radar 21 may be disposed on a casing of the nacelle 12 of the wind turbine generator system, between a rotation plane of an impeller of the wind turbine generator system and a vertical plane of a center line of the tower 13. That is, the laser radar 21 is located between the rotation plane of the plurality of blades 11 of the wind turbine generator system and the vertical plane where the center line 14 of the tower 13 is located. The vertical plane is parallel to the plane of rotation of the impeller, i.e. the vertical plane is parallel to the plane of rotation of the plurality of blades 11. In some examples, as shown in FIG. 2, lidar 21 may be disposed at a bottom of the housing of nacelle 12. In other examples, as shown in FIG. 3, lidar 21 may be disposed atop the housing of nacelle 12.
A plane formed by the plurality of laser beams 23 emitted from the laser radar 21 intersects with the rotation plane of the impeller, and the plurality of laser beams are rotationally scanned around the scanning rotation axis passing through the laser radar 21. As shown in fig. 4, the laser beams 23 emitted from the laser radar 21 may be scanned rotationally about a scanning rotation axis 24 in the direction of the arrow in fig. 4, that is, the laser radar 21 may be scanned rotationally, and the scanning rotation axis 24 passes through the laser radar 21. Specifically, during one scanning cycle of laser radar 21, plurality of laser beams 23 may be rotated 360 ° around scanning rotation axis 24, i.e., laser radar 21 may be rotated to scan 360 ° during one scanning cycle. By the rotational scanning, the laser radar 21 can sense information of the surrounding three-dimensional space (X, Y, Z). In some examples, the scanning rotation axis 24 may be parallel to the axis of the impeller, and the plane formed by the multiple laser beams 23 may be perpendicular to the rotation plane of the impeller, so that the distance reliability represented by the acquired distance measurement data is stronger, and the accuracy of monitoring the tower clearance of the wind turbine generator system is further improved.
Fig. 5 is a schematic diagram of an example of a laser beam emitted by a laser radar provided in a wind turbine generator system according to an embodiment of the present application. Fig. 6 is a schematic diagram of an example of a laser beam emitted by a laser radar disposed on a wind turbine generator system according to an embodiment of the present disclosure. As shown in fig. 5 and 6, the plane formed by the plurality of laser beams 23 emitted from the laser radar 21 intersects with the rotation plane of the impeller, that is, the plane formed by the plurality of laser beams 23 emitted from the laser radar 21 intersects with the rotation plane of the blade 11. Part of the laser beams 23 in the plurality of laser beams 23 are shielded by the blades 11 and the towers 13, and the other part of the laser beams 23 are not shielded by the blades 11 and the towers 13. The plurality of laser beams 23 are rotatably scanned in the direction of the dotted arrow in fig. 6.
The industrial personal computer 22 is connected to the laser radar 21, and the connection between the industrial personal computer 22 and the laser radar 21 may be a wired connection or a wireless connection, which is not limited herein. The industrial personal computer 22 may be configured to obtain ranging data from the laser radar 21, obtain the number of the laser beams 23 that are not shielded by the blade 11 and the tower 13 according to the ranging data and the blade length of the blade 11 of the wind turbine generator system, and send a clearance early warning signal when the number of the laser beams 23 that are not shielded by the blade 11 and the tower 13 is smaller than the number of the laser beams 23 that are not shielded by the blade 11 and the tower 13 under the condition of the reference clearance value.
The distance represented by the ranging data corresponding to a laser beam 23 is less than the blade length, and it is considered that the laser beam 23 is blocked by the blade 11 and/or the tower 13. The reference clearance value is the clearance value under the normal condition of the wind generating set. The number of the laser beams 23 which are not shielded by the blades 11 and the tower 13 is smaller than the number of the laser beams 23 which are not shielded by the blades 11 and the tower 13 under the condition of the reference clearance value, which indicates that the current clearance value of the wind generating set is smaller than the reference clearance value, that is, the current tower clearance of the wind generating set is abnormal, and blade tower sweeping is likely to occur. Under the condition, clearance early warning can be carried out through the clearance early warning signal, and the tower clearance abnormity of the wind generating set of the operator or the related staff is prompted, so that the operator or the related staff can take corresponding measures in time, and the safety of the wind generating set is ensured.
The number of the laser beams 23 which are not shielded by the blade 11 and the tower 13 is greater than or equal to the number of the laser beams 23 which are not shielded by the blade 11 and the tower 13 under the condition of the reference clearance value, which indicates that the current clearance value of the wind generating set is greater than or equal to the reference clearance value, that is, the current tower clearance of the wind generating set is normal, and a clearance early warning signal does not need to be sent out.
In some examples, the number of transceiver components may include, but is not limited to, 16, 32, or 64, i.e., the number of laser line beams emitted by lidar 21 may include, but is not limited to, 16, 32, or 64. The more the number of the receiving and transmitting assemblies in the laser radar 21 is, the more the number of laser beams sent by the laser radar 21 is, the higher the clearance monitoring precision of the tower of the wind generating set is, and the more accurate the clearance early warning is.
For example, lidar 21 includes 16 transceiver modules capable of emitting 16 laser beams. The scanning frequency of the laser radar 21 is 10 hz, and the scanning period is 100 ms. The ranging data corresponding to 16 laser beams 23 within 100 milliseconds may be acquired, resulting in a range characterized by the ranging data corresponding to 16 laser beams 23 within 100 milliseconds. If the distance represented by the ranging data corresponding to 14 of the 16 laser beams 23 is smaller than the blade length and the number of the laser beams 23 not shielded by the blade 11 and the tower 13 is 4 under the condition of the reference clearance value, that is, the number of the laser beams 23 not shielded by the blade 11 and the tower 13 is 2 and is smaller than the number 4 of the laser beams 23 not shielded by the blade 11 and the tower 13 under the condition of the reference clearance value, the industrial personal computer 22 may send a clearance early warning signal.
In the embodiment of the application, the laser radar 21 can be selected according to a specific application scene, so that parameters such as the number of laser beams, scanning frequency, scanning period, ranging capability, precision and angular resolution of the laser radar 21 can meet the requirement of tower clearance monitoring of the wind generating set.
In the embodiment of the present application, the laser radar 21 may be disposed in a nacelle housing of the wind turbine generator system. The laser radar 21 is located between a rotating plane of an impeller of the wind generating set and a vertical plane where a center line of a tower barrel is located. The plurality of receiving and transmitting components of the laser radar 21 can emit a plurality of laser beams 23, a plane formed by the plurality of laser beams intersects with a rotation plane of the impeller, and the plurality of laser beams 23 are rotationally scanned around a scanning rotation axis 24, so that parts of the plurality of laser beams 23 emitted by the laser radar 21 are shielded by the blade 11 and/or the tower 13. The industrial personal computer 22 may determine the laser beam that is not shielded by the blade and the tower based on the distance measurement data corresponding to the laser beam 23 emitted by the laser radar 21 and the blade length of the blade 11. The number of the laser beams 23 which are not shielded by the blades 11 and the tower 13 is smaller than the number of the laser beams 23 which are not shielded by the blades 11 and the tower 13 under the condition of the reference clearance value, which means that the current tower clearance value of the wind generating set is smaller than the reference clearance value, namely the current tower clearance of the wind generating set is abnormal, and an early warning can be sent out through a clearance early warning signal so as to avoid the occurrence of blade tower sweeping, so that the clearance monitoring of the tower of the wind generating set is realized, and the safety of the wind generating set is improved.
In some embodiments, in order to ensure stability of the lidar 21 arrangement, the lidar 21 may be coupled to the nacelle 12 housing by a bracket.
Fig. 7 is a schematic diagram of an example of connection of a lidar to a nacelle housing according to an embodiment of the present disclosure. As shown in fig. 7, the lidar 21 is located at the bottom of the housing of the nacelle 12 and is connected to the housing of the nacelle 12 by a first bracket 25. The first bracket 25 may be connected to the nacelle 12 housing by bolts or other means, but is not limited thereto. First bracket 25 and lidar 21 may be bolted or otherwise connected, but are not limited thereto. In some examples, as shown in fig. 7, first support 25 may include an L-shaped support having one end fixedly coupled to the nacelle 12 housing and another end fixedly coupled to lidar 21. The specific implementation of the connection of the L-shaped bracket to the housing of nacelle 12 and the fixed connection to lidar 21 is not limited herein. In some examples, in the case that the laser radar 21 is connected to the housing of the nacelle 12 through the first support 25, the inclination angle of the end of the first support 25 connected to the laser radar 21 is the same as the elevation angle of the impeller, so that the scanning rotation axis 24 of the multiple laser beams 23 emitted by the laser radar 21 is parallel to the axis of the impeller, the distance represented by the obtained ranging data is more reliable, and the accuracy of monitoring the tower clearance of the wind turbine generator system is further improved.
Fig. 8 is a schematic diagram of another example of the connection of the lidar to the nacelle cover provided by the embodiment of the present application. As shown in fig. 8, the lidar 21 is located at the top of the nacelle 12 housing and is attached to the nacelle 12 housing by a second bracket 26. The second bracket 26 may be bolted or otherwise connected to the nacelle 12 housing, but is not limited thereto. Second bracket 26 and lidar 21 may be bolted or otherwise attached, but are not limited thereto. In some examples, as shown in FIG. 8, second bracket 26 may include an L-shaped bracket having one end fixedly coupled to the outer shell of nacelle 12 and another end fixedly coupled to lidar 21. The specific implementation of the connection of the L-shaped bracket to the housing of nacelle 12 and the fixed connection to lidar 21 is not limited herein. In some examples, in the case that the laser radar 21 is connected to the housing of the nacelle 12 through the second support 26, the inclination angle of the end, to which the second support 26 is connected, of the second support 26 is the same as the elevation angle of the impeller, so that the scanning rotation axis 24 of the multiple laser beams 23 emitted by the laser radar 21 is parallel to the axis of the impeller, the distance represented by the acquired ranging data is more reliable, and the accuracy of monitoring the tower clearance of the wind turbine generator system is further improved.
In some examples, the industrial personal computer 22 may acquire ranging data from the laser radar 21 for a plurality of laser beams within a predetermined rotational angle range around the scanning rotational axis 24. For example, fig. 9 is a schematic diagram of an example of the predetermined rotation angle range provided in the embodiment of the present application. As shown in FIG. 9, the predetermined rotational angle range is α, and the axis of symmetry 27 of the predetermined rotational angle range is parallel to the centerline of the tower 13. In order to ensure that at least two blades 11 of the wind turbine generator set can be scanned, the predetermined rotation angle range α may be greater than or equal to 120 °, and may be set according to an application scenario and an application requirement, which is not limited herein. The predetermined rotational angle range α includes, for example, 120 °, 150 °, or 180 °.
The ranging data of the laser beams obtained from the laser radar 21 in the predetermined rotation angle range α around the scanning rotation axis 24 is sufficient for determining the number of the laser beams not shielded by the blade 11 and the tower 13, and all the ranging data obtained by rotating the laser beams around the scanning rotation axis 24 by 360 ° is not required to be obtained, so that the resource occupied by determining the number of the laser beams not shielded by the blade 11 and the tower 13 is reduced, and the process of determining the number of the laser beams not shielded by the blade 11 and the tower 13 is simplified.
In some embodiments, the wind turbine generator system tower clearance monitoring system may further include a Programmable Logic Controller (PLC). FIG. 10 is a schematic structural diagram of a wind generating set tower clearance monitoring system according to still another embodiment of the present disclosure. As shown in FIG. 10, the difference between FIG. 2 and FIG. 10 is that the wind turbine tower clearance monitoring system shown in FIG. 10 may further include a programmable logic controller 27.

The programmable logic controller 27 may be embodied as a fan controller or other controller, processor, device, etc., without limitation. The programmable logic controller 27 is used for receiving the clearance early warning signal sent by the industrial personal computer 22 and controlling the pitch of the wind generating set according to the clearance early warning signal. Specifically, the programmable logic controller 27 receives the clearance early warning signal sent by the industrial personal computer 22, and can control the wind generating set to take in the oar, so as to avoid the wind generating set from continuously operating to cause the blade to sweep the tower, thereby avoiding the damage to the wind generating set and ensuring the safety of the wind generating set.
