Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation equipment control, and in particular to a method, device, equipment and storage medium for controlling the load of wind power generation equipment. Background Art

[0002] Wind turbines convert wind energy into mechanical work, which in turn drives the rotor to ultimately output alternating current. These devices typically consist of a rotor (including blades), a generator, a yaw device, a tower, a speed limiter, and an energy storage device. During rotation, wind turbines are subject to aerodynamic forces generated by the wind, combined with their own gravity and inertia. These forces can impose significant loads on the wind turbine, potentially causing structural damage. Therefore, load control is essential.

[0003] Taking the blades of wind turbines as an example, the wind turbines have three blades, and the roots of the three blades all have large limit loads. In related technologies, in order to reduce the limit loads of the blade roots, a load sensor is usually installed at the roots of the three blades respectively, and the measured three-blade root bending moment load is transformed by dq to obtain the loads of the d-axis and q-axis. Subsequently, PI calculation is performed to obtain the pitch requirements of the d-axis and q-axis. The obtained pitch requirements of the d-axis and q-axis are subjected to dq inverse transformation to obtain different additional pitch rates for the three blades. Finally, the additional pitch rate is superimposed on the uniform pitch rate to obtain the pitch requirements of the three blades respectively. Finally, the pitch requirements of the three blades are transmitted to the respective actuators of the blades to realize independent pitch control.

[0004] However, the above technology requires additional load sensors, which will greatly increase the design cost of the entire machine. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] Currently, when controlling the load of wind turbines, taking the load on the blades of wind turbines as an example, there are two common load control strategies, including unified pitch control and independent pitch control. Among them, unified pitch control is the most commonly used pitch control method. The pitch angle of all blades changes in the same way. In unified pitch control, the wind turbine will calculate the blade pitch angle requirement based on parameters such as the current speed, power, pitch angle, and nacelle acceleration. This pitch angle requirement is then transmitted to the pitch actuators of the three blades to ensure that the three blades execute the same pitch requirement. However, if the three blades of the unified pitch control execute the same pitch requirement, the unbalanced load on the impeller surface of the wind turbine cannot be reduced. Independent pitch control generally requires the installation of a load sensor at the blade root, performing a dq transformation on the measured three-blade root bending moment load to obtain the loads on the d-axis and q-axis, and then performing a PI calculation to obtain the pitch requirements of the d-axis and q-axis. The obtained pitch requirements of the d-axis and q-axis are then subjected to a dq inverse transformation to obtain different additional pitch rates for the three blades. Finally, the additional pitch rates are superimposed on the uniform pitch rate to obtain the pitch requirements of the three blades. Finally, the pitch requirements of the three blades are transmitted to the respective actuators of the blades to realize independent pitch control. However, although independent pitch control can reduce the unbalanced load within the impeller surface, it requires additional load sensors, which will greatly increase the design cost of the entire machine. Based on this, the embodiments of the present invention provide a load control method, device, equipment and storage medium for wind power generation equipment, which can solve the above technical problems.

[0030] It should be noted that the methods of the embodiments of the present invention can be executed by a load control device of a wind turbine generator system, by an electronic device within the wind turbine generator system, by the wind turbine generator system itself, or by other devices or equipment, without specific limitation herein. The following embodiments will be described using an electronic device as the execution subject.

[0031] Figure 1 This is one of the flow charts of the wind power generation equipment load control method provided by the present invention, such as Figure 1 As shown, the method includes the following steps: Step 102: Determine at least one target component in the wind power generation equipment that requires load control.

[0032] The loads of various components in the wind turbine during historical operation can be collected in advance, and statistical analysis can be performed to identify components whose loads during operation may be excessive, potentially affecting equipment performance. These components can then be used as target components for load control. The target components identified here can be a single type of target component in the wind turbine, or multiple different types of target components in the wind turbine. Each type of target component in the wind turbine can include one or more target components.

[0033] In addition, the target components mentioned above may be blades / impellers, hubs, yaws, towers, etc. in wind power generation equipment.

[0034] Step 104 , obtaining a target azimuth angle interval corresponding to the target component; the target azimuth angle interval is determined by simulating the load of the target component at different azimuth angles, and the target azimuth angle interval is an azimuth angle interval in which the load of the target component needs to be controlled.

[0035] In this step, after determining the target components that need to be load controlled, for one or more target components of the same type in the wind power generation equipment, the load of the target components can be simulated through the actual working conditions of the target components combined with the whole machine simulation model of the wind power generation equipment. During the simulation process, the load of the target components at different azimuth angles under actual working conditions can be statistically obtained.

[0036] Afterwards, the load of the target component at different azimuth angles obtained by simulation can be used to determine the azimuth angle range in which load control is required. Generally, load control is to reduce the higher load of the target component under actual working conditions. Based on this, the azimuth angle range with a larger load can be determined from the load of the target component at different azimuth angles obtained by simulation, and then this azimuth angle range can be used as the target azimuth angle range corresponding to the target component. It is understandable that the target azimuth angle range here can include one or more azimuth angles. For example, when multiple azimuth angles are included, it can include the two endpoints in the target azimuth angle range, namely the maximum azimuth angle and the minimum azimuth angle.

[0037] Furthermore, for target components of the same type within the same wind turbine generator system, their operating patterns or load variation trends / patterns are generally similar. Therefore, the target azimuth angle interval determined for the same type of target component within the same wind turbine generator system is generally the same. However, the target azimuth angle intervals determined for different types of target components within the same wind turbine generator system may be different.

[0038] Step 106 : During the operation of the target component, the current azimuth angle of the target component is obtained. If the current azimuth angle of the target component successfully matches the target azimuth angle interval, the current load of the target component is subjected to load reduction control.

[0039] Among them, after determining the target azimuth angle interval corresponding to the target component for load control, the target azimuth angle interval can be set in the electronic device, and during the actual operation or simulation operation of the target component, the current azimuth angle of the target component can be continuously collected, and the current azimuth angle of the target component and its corresponding target azimuth angle interval can be matched. If the current azimuth angle of the target component successfully matches the target azimuth angle interval corresponding to it, that is, the current azimuth angle of the target component enters the target azimuth angle interval corresponding to it, then it is determined that the current load of the target component needs to be controlled, and specifically, the load reduction control function can be turned on to reduce the current load of the target component through the algorithm corresponding to the load reduction control function. The algorithm corresponding to the load reduction control function here can be an algorithm for variable pitch control of the target component, such as increasing the current pitch angle of the target component, etc. In short, the load reduction of the target component can be achieved. After the current azimuth angle of the target component exceeds the target azimuth angle interval, the load reduction control function is turned off to avoid excessive load reduction of the target component.

[0040] After load reduction control is implemented, the target component's current load will be less than when load reduction control is disabled. This allows load reduction within the target component's target azimuth angle range without requiring additional blade root load sensors, thus reducing overall turbine design costs. Furthermore, whether load reduction control is enabled is determined by whether the target component's current azimuth angle matches the target azimuth angle range. This conditional determination allows for precise load reduction of the target component, improves control fault tolerance, and reduces malfunctions of the wind turbine unit.

[0041] In this embodiment, at least one target component in a wind turbine generator system requiring load control is determined, a target azimuth angle interval corresponding to the target component is obtained, and during operation of the target component, the current azimuth angle of the target component is obtained. If the current azimuth angle of the target component successfully matches the target azimuth angle interval, load reduction control is performed on the current load of the target component. The target azimuth angle interval is determined by simulating the load of the target component at different azimuth angles, and the target azimuth angle interval is the azimuth angle interval within which the load of the target component is required to be controlled. In this method, since the target azimuth angle interval corresponding to the target component in the wind turbine generator system requiring load control can be predetermined through simulation, and load reduction control can be performed on the target component when the azimuth angle of the target component during operation enters the target azimuth angle interval, load control can be achieved without adding a load sensor, thereby not increasing the overall design cost of the wind turbine generator system, thereby reducing the overall design cost.

[0042] The following embodiments illustrate a specific process of obtaining a target azimuth angle interval corresponding to a target component.

[0043] Figure 2 This is the second flow chart of the wind power generation equipment load control method provided by the present invention, such as Figure 2 As shown, the above step 104 obtains the target azimuth angle interval corresponding to the target component, which may include the following steps: Step 202: Acquire environmental parameters of the wind power generation equipment under different operating conditions.

[0044] The wind turbine generator system includes target components. Environmental parameters corresponding to the wind turbine generator system and its target components under different actual operating conditions can be collected. These environmental parameters may include wind speed, wind direction, turbulence, shear angle, ambient temperature, ambient humidity, altitude, etc. Environmental parameters under different operating conditions, as well as specific values ​​or ranges of these parameters, can be pre-set to provide a data foundation for subsequent simulation of the target components within the wind turbine generator system.

[0045] In step 204, the environmental parameters under different working conditions are input into the whole machine simulation model for load simulation processing to determine the corresponding time series data of the target components of the wind power generation equipment under different working conditions; the above time series data includes different azimuth angles of the target components under the corresponding working conditions and the simulated load at each azimuth angle.

[0046] Among them, after setting the environmental parameters under different working conditions as mentioned above, a set of environmental parameters under different working conditions can be obtained, and then a set of environmental parameters for each working condition can be input into the whole machine simulation model of the wind power generation equipment for load simulation processing. At the same time, the azimuth angle value range can be pre-set in the whole machine simulation model, that is, the azimuth angle range of the target component rotation, for example, it can be 0°~360°.

[0047] The above-mentioned whole-machine simulation model can simulate the actual operation of the target component under different working conditions through the environmental parameters of different working conditions. For example, for each working condition, the whole-machine simulation model can simulate the load of the target component under different azimuth angles of the working condition through the environmental parameters of the working condition and parameters such as the azimuth angle range. The different azimuth angles are related to the simulation time, that is, the azimuth angle of the target component is also changing with the passage of time.

[0048] In summary, the whole-machine simulation model can be used to obtain the load (referred to as the simulated load) on the target component at different azimuth angles under each operating condition. This means that time series data for the target component under different operating conditions can be obtained. Each operating condition corresponds to a set of time series data, which can include the simulated load corresponding to each azimuth angle of the target component under that operating condition, and can also reflect the changing trend of the simulated load on the target component under different azimuth angles. The simulated load here can be the load at the base of the target component, the load at the top, or the load at other parts of the target component, without specific restrictions here.

[0049] In addition, the time series data of different working conditions can be output graphically for users to view, and it is also convenient for users to select and check the target azimuth angle interval determined subsequently.

[0050] For example, the root loads of three blades of a wind turbine are simulated using a whole-machine simulation model. The three blades are blade 1, blade 2, and blade 3. Assuming there are multiple working conditions, see Figure 3 The scatter plot of the root load of the three blades shown versus the impeller azimuth angle (blade azimuth angle), referred to as load and blade angle (K17) in the figure, shows time series data for each blade under various operating conditions. The purple data is a scatter plot of the load versus azimuth angle for blade 1 under different operating conditions, the red data is a scatter plot of the load versus azimuth angle for blade 2 under different operating conditions, and the orange data is a scatter plot of the load versus azimuth angle for blade 3 under different operating conditions. Furthermore, the load of the blades described above may be the root load of the blades, specifically the Mxy load at the root, which is the vector sum of the Mx load and the My load at the root.

[0051] Step 206 : determining a target azimuth angle range corresponding to the target component according to different azimuth angles of the target component under each working condition and the simulated load at each azimuth angle.

[0052] In this step, when performing load simulation on the target component, the load simulation can be performed separately for each target component to obtain multiple sets of time series data corresponding to each target component. Then, the target azimuth angle interval of the target component can be determined based on the multiple sets of time series data for each target component. As mentioned herein, the target component can be a single target component or multiple target components of the same type. The following describes the process of determining the target azimuth angle interval when the target component is a single target component and the process of determining the target azimuth angle interval when the target components are multiple target components of the same type, respectively.

[0053] Scenario 1: For a case where the target component is a target component, step 206 may include the following steps to determine the target azimuth angle range corresponding to the target component based on the different azimuth angles of the target component under each working condition and the simulated load at each azimuth angle: Step A1: Determine the maximum simulated load of the target component under each working condition based on the different azimuth angles of the target component under each working condition and the simulated load under each azimuth angle, and obtain the candidate azimuth angle corresponding to the maximum simulated load under each working condition.

[0054] Step A2: determining a target azimuth angle interval corresponding to the target component based on the candidate azimuth angles under each working condition and the preset azimuth angle offset.

[0055] Among them, for the multiple sets of time series data of the target component, statistical processing is performed on them to find out that the multiple sets of time series data of the target component all have peaks in a certain azimuth interval, so a target azimuth interval corresponding to the target component can be determined. When determining the target azimuth interval, the maximum simulation load in each set of time series data of the target component can be obtained by sorting, etc., and then the azimuth corresponding to the maximum simulation load is obtained in each time series data, and both are recorded as candidate azimuths. After that, the multiple candidate azimuths can be averaged or the maximum value, median, etc. can be directly selected to obtain a target azimuth corresponding to the multiple candidate azimuths, such as 90°.

[0056] Since a certain margin is required during load control to avoid the impact of the target component caused by a too narrow azimuth angle range, a preset azimuth angle offset can be determined based on the condition of not causing impact on the target component, such as ±30°, and then the preset azimuth angle offset is added to the above-determined target azimuth angle to obtain the final target azimuth angle range, such as (60°~120°).

[0057] Here, in the scenario of a target component, by finding the maximum simulated load of the target component in the time series data of multiple working conditions, and based on the azimuth angle corresponding to each maximum simulated load, combined with the preset azimuth angle offset, the target azimuth angle interval corresponding to the target component is determined. In this way, the target azimuth angle interval corresponding to a target component can be determined more accurately and quickly, and the determined target azimuth angle interval is more in line with the actual situation, so that the subsequent load reduction control of the target component can be effectively implemented based on this.

[0058] Scenario 2: For a case where there are multiple target components and the multiple target components are of the same type, step 206 may determine the target azimuth angle range corresponding to the target component based on the different azimuth angles of the target component under each working condition and the simulated load at each azimuth angle, and may include the following steps: Step B1, for each target component, determine the maximum simulated load of the target component under each working condition and the candidate azimuth angle corresponding to the maximum simulated load based on the different azimuth angles of the target component under each working condition and the simulated load at each azimuth angle, and determine the first target azimuth angle based on the candidate azimuth angles of the target component under each working condition.

[0059] Step B2: Determine a reference component and other components other than the reference component among multiple target components, and perform azimuth transformation processing on the first target azimuth of the other components according to the installation position of each target component in the wind turbine generator system to determine the second target azimuth corresponding to the other components; the second target azimuth of the other components is the azimuth of the other components in absolute coordinates.

[0060] Step B3: determining a target azimuth angle interval corresponding to the plurality of target components as a whole according to the first target azimuth angle of the reference component and the second target azimuth angles of the other components.

[0061] Among them, when the target components are multiple target components of the same type, for each target component, the maximum simulation load in each set of time series data can be statistically obtained in its multiple sets of time series data, and then the azimuth corresponding to the maximum simulation load can be obtained in the corresponding time series data, all of which are recorded as candidate azimuths. After that, the multiple candidate azimuths can be averaged or the maximum value, median, etc. can be directly selected to obtain a target azimuth corresponding to the multiple candidate azimuths, which is recorded as the first target azimuth, for example, 90°. Here, each target component can statistically obtain its own corresponding first target azimuth.

[0062] In addition, when the target components are multiple target components of the same type, the installation positions of these multiple target components in the wind turbine may be different. For example, these multiple target components may be three blades in the wind turbine, and the three blades are installed 120° apart, that is, each blade is 120° apart from the previous blade. This will cause the simulated load variation trends with azimuth angle in multiple sets of time series data for the multiple target components to appear dissimilar, which is not conducive to the subsequent determination of the target azimuth angle interval corresponding to the multiple target components as a whole. However, in reality, the simulated load variation trends with azimuth angle in the multiple sets of time series data obtained for these multiple target components should be roughly the same, except that there will be an offset in azimuth angle. Based on this, in this embodiment, based on the installation position of each target component in the wind turbine, a target component is first selected from the multiple target components as a reference component. For example, taking the three blades in the wind turbine as an example, the blades installed in the proportional direction can be used as the reference component, and then the remaining target components in the multiple target components except the reference component are all regarded as other components.

[0063] After the reference component and other components are divided, the first target azimuth angle of each other component can be changed according to the installation position of the other component in the wind turbine generator system and the installation position of the reference component in the wind turbine generator system, so as to convert the first target azimuth angle into an azimuth angle in the absolute coordinate system. For example, taking the three blades in the wind turbine generator system as an example, see Figure 3The multiple sets of time series scatter plots for the three blades shown in the figure assume that the reference component is blade 1, which is installed in the north direction with a mounting angle of 0° and a first target azimuth angle of approximately 90°. The mounting angles of the other two components (blades 3 and 2) are 120° and 240°, respectively, and their corresponding first target azimuth angles are approximately 210° and 330°, respectively. Here, azimuth conversion is required for blades 3 and 2 to convert their first target azimuth angles to the absolute coordinate system. During the azimuth conversion, since the mounting angle difference between blades 3 and 1 is 240°, 240° can be subtracted from blade 3's first target azimuth angle of 330° to obtain the second target azimuth angle of 90° corresponding to blade 3 in the absolute coordinate system. Similarly, since the mounting angle difference between blades 2 and 1 is 120°, 120° can be subtracted from blade 2's first target azimuth angle of 210° to obtain the second target azimuth angle of 90° corresponding to blade 2 in the absolute coordinate system.

[0064] After obtaining the first target azimuth angle of the reference component and the second target azimuth angles of the other components among the multiple target components, the target azimuth angle interval corresponding to the multiple target components as a whole can be determined accordingly. As an optional embodiment, this can be achieved in the following manner: A third target azimuth angle corresponding to the plurality of target components as a whole is determined based on the first target azimuth angle of the reference component and the second target azimuth angles of the other components; and a target azimuth angle interval corresponding to the plurality of target components as a whole is determined based on the third target azimuth angle and a preset azimuth angle offset.

[0065] Among them, under normal circumstances, the first target azimuth of the reference component and the second target azimuth of the other components should be not much different. At this time, the first target azimuth of the reference component and the second target azimuth of the other components can be averaged, and the obtained average value can be used as the third target azimuth corresponding to the multiple target components as a whole; or, any azimuth among the first target azimuth of the reference component and the second target azimuth of the other components can be used as the third target azimuth; or, the median of the first target azimuth of the reference component and the second target azimuth of the other components can be used as the third target azimuth; or other methods can be used, which are not specifically limited here. It should be noted that the difference between the third target azimuth determined here and the first target azimuth and the second target azimuth is within a certain range, that is, the difference is not large.

[0066] After determining the third target azimuth angle, the preset azimuth angle offset in the above scenario 1 can be used to add the preset azimuth angle offset to the first target azimuth angle to obtain the target azimuth angle range corresponding to the multiple target components as a whole, for example (60°~120°).

[0067] Here, in the scenario of multiple target components of the same type, the maximum simulated load of each target component in the time series data of multiple working conditions is found, and the first target azimuth angle of each target component is determined based on the azimuth angle corresponding to each maximum simulated load. Then, the first target azimuth angles of other components in the multiple target components are transformed into an absolute coordinate system based on the reference component, and the target azimuth angles corresponding to all target components are determined. In combination with the preset azimuth angle offset, the target azimuth angle interval corresponding to the multiple target components as a whole is determined. In this way, the target azimuth angle interval corresponding to the multiple target components can be determined more accurately, and the determined target azimuth angle interval is more in line with the actual situation, so that the subsequent load reduction control of the multiple target components can be effectively achieved through a target azimuth angle interval. It should be noted that generally there is only one load peak in a set of time series data, which makes it easy to accurately obtain a maximum load and its corresponding azimuth angle interval.

[0068] In addition, when wind power generation equipment is installed at an unused site, different target azimuth angle intervals can be set in the evaluation area according to the simulation load of the special site stage, so as to enhance the applicability and versatility of the load reduction control function and realize the rapid transplantation of the load reduction control function.

[0069] In this embodiment, by obtaining the environmental parameters of the target components of the wind power generation equipment under different working conditions and combining them with the whole machine simulation model to obtain the time series data of the target components under different working conditions, and determining the target azimuth angle interval corresponding to the target components based on the change trend of the simulated load with the azimuth angle in multiple sets of time series data, the accuracy of the determined target azimuth angle interval can be improved through multiple working condition simulations, thereby improving the accuracy of the subsequent load control of the target components. In addition, the target azimuth angle interval corresponding to a target component and multiple target components as a whole can be determined separately, which can improve the applicability of the load control scheme. Furthermore, when determining the target azimuth angle interval corresponding to multiple target components as a whole, the azimuth angles of the multiple target components can be transformed into the same absolute coordinate system for calculation, which can improve the accuracy of the target azimuth angle interval corresponding to the determined target component as a whole, thereby improving the accuracy and effectiveness of the subsequent load control of each target component in the multiple target component scenario.

[0070] The following embodiment specifically describes a process of performing load control on each target component when the target component includes multiple target components of the same type.

[0071] Figure 4 This is the third flow chart of the wind power generation equipment load control method provided by the present invention, see Figure 4As shown, in the above step 106, during the operation of the target component, the current azimuth angle of the target component is obtained. If the current azimuth angle of the target component successfully matches the target azimuth angle interval, the current load of the target component is subjected to load reduction control, which may include the following steps: Step 302: During the operation of multiple target components, obtain the current azimuth angle and the current pitch angle of each target component.

[0072] Step 304 : Perform azimuth transformation processing on the current azimuth of each target component to determine the current absolute azimuth of each target component.

[0073] Step 306: If the current absolute azimuth angle of the first target component successfully matches the target azimuth angle interval, the preset pitch angle is added to the current pitch angle of the first target component to determine the target pitch angle of the first target component after the pitch is changed; the load of the first target component when adopting the target pitch angle is lower than the load of the first target when adopting the current pitch angle, and the first target component is any target component among the multiple target components.

[0074] Optionally, the plurality of target components include three blades of a wind power generation device, and the load reduction control is specifically to reduce the root limit loads of the three blades respectively, that is, to reduce the limit loads of the three blades respectively.

[0075] During the specific load shedding process, first, during the actual operation / simulation operation of multiple target components, the current azimuth angle and current pitch angle of each target component can be obtained through sensors or other means. Taking three blades as an example, the azimuth angle refers to the rotation angle of the blade in the horizontal plane, usually expressed as the angle of the blade relative to a fixed reference direction (such as the north direction or a specific position of the wind turbine). It reflects the positional relationship of the blade in the horizontal direction and is mainly used to describe the relative position change of the blade during the rotation of the wind turbine. The pitch angle refers to the angle between the blade and the rotating plane (usually the horizontal plane), also known as the installation angle or windward angle of the blade. It describes the degree of inclination of the blade relative to the rotating plane, directly affects the effect of the blade on the airflow, and is a key parameter for regulating wind turbine performance.

[0076] Afterwards, an absolute coordinate system can be determined, and the current azimuth angle of each target component can be converted to the absolute coordinate system to obtain the current absolute azimuth angle of each target component in the absolute coordinate system. The absolute coordinate system here can be the coordinate system where the reference component selected above is located, or it can be a coordinate system determined by itself. For example, the current azimuth angles of the three blades are all 65°. Taking the coordinate system where blade 1 is located as the reference, after performing the azimuth transformation, it can be known that the absolute azimuth angle of blade 1 is 65°, the absolute azimuth angle of blade 2 is 305°, and the absolute azimuth angle of blade 3 is 185°.

[0077] After obtaining the current absolute azimuth angle of each target component, the current absolute azimuth angle of each target component can be matched with the target azimuth angle interval corresponding to the target component as a whole. If the current absolute azimuth angle of any target component among the target components (recorded as the first target component) falls within the target azimuth angle interval, the first target component can be subjected to load reduction control. Specifically, the load reduction control function can be turned on when the azimuth angle matching is successful, and the preset pitch angle is added to the current pitch angle of the first target component to obtain the current target pitch angle of the first target component. The size of the preset pitch angle here can be set according to actual conditions, for example, it can be 2 degrees. The load reduction control function is turned off after the current azimuth angle of the first target component exceeds the target azimuth angle interval to avoid excessive load reduction on the first target component. For example, taking three blades as an example, assuming that the target azimuth angle range is (60°~120°), when the current azimuth angle of blade 1 is in the range of 60°~120°, the preset pitch angle is added to blade 1, when the current azimuth angle of blade 2 is in the range of 300°~360°, the preset pitch angle is added to blade 2, and when the current azimuth angle of blade 3 is in the range of 180°~240°, the preset pitch angle is added to blade 3.

[0078] It should be noted that the load of the first target component when using the target pitch angle is lower than the load when using the current pitch angle, that is, after increasing the pitch angle of the first target component, its load will be reduced accordingly, thereby realizing variable pitch control of the target component.

[0079] In addition, the above-mentioned multiple target components generally do not enter the target azimuth angle range at the same time, that is, only one target component will be pitched at a time. Therefore, this can achieve the effect of independent pitching, reduce the unbalanced load between the target components, and at the same time reduce the blade root load of each target component.

[0080] For example, see Figure 5 The wind speed comparison diagram when the load reduction function is turned on and off is shown in the figure. Figure 6 The schematic diagram of the comparison of the pitch angle of blade 1 when the load shedding function is turned on and off is shown in FIG. Figure 7 The diagram shown is a comparison diagram of the root load of blade 1 when the load reduction function is turned on and off, where "off" means the load reduction function is turned off, corresponding to the black curve, and "on" means the load reduction function is turned on, corresponding to the red curve.

[0081] Figure 5 The display shows the hub wind speed magnitude changing with time. The unit of hub wind speed magnitude is m / s and the unit of time is s. Figure 5It can be seen that the wind speed does not change much when the load reduction function is turned on and off, and the two curves are basically overlapping.

[0082] Figure 6 The display shows the variation trend of the pitch angle of blade 1 over time. The unit of pitch angle is deg and the unit of time is s. Figure 6 It can be seen from the figure that when the load shedding function is turned on, the pitch angle of the blade 1 increases at certain times, and at other times is the same as the pitch angle of the blade 1 when the load shedding function is turned off.

[0083] Figure 7 The following table shows the trend of the blade root load Blade1 Mxy (Root axes) changing with time. The unit of the blade root load is kNm and the unit of time is s. Figure 7 It can be seen from the figure that when the load shedding function is turned off, the root load value of blade 1 is greater than 30000 kN at about 180 s of simulation time, while when the load shedding function is turned on, the root load value of blade 1 is less than 30000 kN.

[0084] It can be seen that the blade load reduction method based on the target azimuth angle range of the blade in this embodiment can effectively reduce the blade root limit load.

[0085] It can be understood that although the above figure shows a schematic diagram related to the simulated load reduction of blade 1, for other blades, their corresponding schematic diagrams related to the simulated load reduction can be obtained in the above manner.

[0086] In this embodiment, by transforming the current azimuth angle of each target component during actual operation and matching the transformed azimuth angle to a target azimuth angle range, the target component's current pitch angle can be increased by a preset pitch angle after a successful match. This allows for precise load shedding control of each target component, improving its effectiveness. Furthermore, this embodiment eliminates the need for additional sensors to implement load shedding control, utilizing the wind turbine's own rotor azimuth angle signal, thereby minimizing overall machine design costs.
