Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a method and system for protecting a wind turbine from vortex-induced resonance. Background Art

[0002] With the continuous development of wind power generation technology, the size and power of wind turbine blades are increasing. Blade vortex-induced vibration is common in large wind turbines above 4MW, among which the vortex-induced vibration of wind turbines is mainly tower vortex-induced. Tower vortex-induced vibration is the vibration caused by the vortexes that are regularly shed and alternately formed on the leeward side of the tower when the wind speed is within a certain range and the airflow passes through the smooth tower surface. Tower vortex-induced vibration is a resonance phenomenon. It requires that the vortex shedding frequency is close to the natural frequency of the tower and that a certain excitation time is maintained to form obvious vortex-induced vibration. When the wind turbine is connected to the grid and operating normally, due to the disturbance of the airflow caused by the rotation of the wind rotor, the unit will not experience vortex-induced vibration. The vortex-induced vibration of the unit occurs during the shutdown and wind waiting process. If the tower vortex-induced vibration occurs during the wind waiting process, it may cause resonance between the tower and the wind turbine transmission chain mechanism, causing serious equipment damage and safety accidents. At present, the existing wind turbine tower vortex-induced protection methods have problems such as low accuracy, slow response speed, and insufficient reliability.

[0003] The purpose of the present invention is to provide an efficient and reliable technology for suppressing vortex-induced resonance of a fan, so as to ensure the stable operation of the fan under wind-waiting conditions, reduce the damage of vortex-induced resonance to the fan structure, and extend the service life of the fan.

[0004] Therefore, in order to solve the above problems, a method and system for protecting wind turbine tower from vortex-induced resonance is proposed, which reduces the risk of vortex-induced resonance of the tower by adjusting the yaw direction to wind and the angle of wind turbine blades in standby mode.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0029] Example 1, reference Figure 1 , is an embodiment of the present invention, which provides a method for protecting a wind turbine from vortex-induced resonance, comprising:

[0030] S1: Monitor and collect data to obtain a type of data.

[0031] It should be noted that if Figure 1 As shown in S1, the data collection includes real-time monitoring of the fan operation status through the system and collecting relevant data for subsequent analysis and judgment.

[0032] Furthermore, the first category of data includes data obtained through the first-level method, including environmental condition data, unit operating status data, structural monitoring data, historical operating data, and risk warning data;

[0033] Among them, the unit operating status data includes rotation speed, blade angle, power generation and yaw angle.

[0034] Furthermore, the first-level method is completed through a distributed sensor network and dynamic monitoring technology. The sensor network is used to collect data from key locations in real time; the dynamic monitoring technology is used to record and update data.

[0035] Specifically, environmental condition data include information such as wind speed, wind direction, temperature, and humidity, which can reflect the impact of the external environment on the operation of the wind turbine; structural monitoring data include the stress, strain, and vibration characteristics of key components of the unit, which are used to evaluate the operating health of the equipment; historical operating data are used to analyze long-term operating trends and identify abnormal changes; risk warning data is based on the comparison of real-time collected data with thresholds to identify possible abnormal risk factors.

[0036] In an embodiment of the present application, one type of data is environmental condition data, unit operating status data, structural monitoring data, historical operating data and risk warning data, among which the environmental condition data is used to evaluate in real time the potential impact of the external environment on the operation of the wind turbine; the unit operating status data is used to reflect the current working status of the wind turbine, such as parameters such as speed, blade angle, power generation and yaw angle, to provide support for dynamic adjustment of the system; the structural monitoring data can monitor the health status of key components of the wind turbine, help identify abnormal stress and vibration conditions, and prevent structural failures; historical operating data provides a reference for optimizing operating strategies and predicting potential risks through long-term trend analysis; risk warning data is based on the comparison of real-time data with set thresholds, which can quickly identify and warn of abnormal operating conditions, providing a basis for the timely initiation of protective measures.

[0037] In an optional embodiment, a type of data can also be obtained through other methods, such as obtaining data through periodic collection rather than real-time monitoring; specifically, the system can call sensors to collect data within a set time interval rather than continuously running in real time; this method is suitable for situations where the operating environment is relatively stable and the data does not change drastically, and the occupancy of sensors and system resources can be reduced by reducing the collection frequency; the data includes environmental condition data (such as wind speed, wind direction, temperature, humidity, etc.) and unit operating status data (such as speed, blade angle, etc.), which are stored in the local device and then transmitted in batches to the central control system for analysis and processing.

[0038] In an optional embodiment, a type of data can also be realized in other ways, such as through manual inspection combined with manual input; specifically, the operation and maintenance personnel observe and record the operating status of the wind turbine through inspection equipment, and the data includes the angular position of the blades, the vibration state of the tower, and basic measurement results of environmental parameters; these data are entered into the system database in the form of manual entry or upload for subsequent analysis; it can be used as a supplementary means to ensure that basic risk assessment and operation adjustments can still be performed under special conditions, thereby reducing potential risks during operation.

[0039] In the embodiment of the present application, the first-level method is to use sensors and dynamic monitoring technology, and the real-time data collection system records and updates data according to the set monitoring frequency to ensure the continuity and real-time nature of the collected data. Specifically, the sensor network includes various types of sensors distributed and deployed at key parts of the wind turbine, such as environmental sensors, vibration sensors, stress sensors, etc., which are used to collect multi-dimensional data such as wind speed, wind direction, temperature, humidity, rotation speed, vibration amplitude, etc.; dynamic monitoring technology is combined with data processing, and the collected data is transmitted to the central processing unit for storage and analysis through a real-time data transmission and recording mechanism;

[0040] Furthermore, the environmental condition data collected in real time is used to evaluate changes in the external environment of the wind turbine; the unit operating status data provides real-time support for dynamically adjusting the wind turbine operating strategy; the structural monitoring data helps identify potential structural risks by capturing the stress, vibration and deformation of key components; the historical operating data provides a basis for optimizing the control strategy by analyzing the long-term operating trends of the system; the risk warning data quickly identifies possible abnormal conditions by comparing the collected data with the set threshold in real time, thereby triggering subsequent protective measures; this first-level method based on sensors and dynamic monitoring technology can effectively improve the accuracy and timeliness of data collection, and provide a reliable basic support for the subsequent risk analysis and operation adjustments of the system.

[0041] In an optional embodiment, the first-level method can also be implemented in other ways, such as using a centralized sensor network combined with a timed acquisition method to complete data monitoring; specifically, this method installs centralized sensors on key components of the wind turbine (such as the top of the tower and the root of the blade) and uses a time interval sampling mode to acquire data instead of continuous real-time monitoring; this timed sampling method can provide basic operating status data, such as rotation speed, blade angle and other key information while reducing equipment operating power consumption and data transmission frequency; the collected data will be stored in the local device and transmitted to the data processing unit at a predetermined time or under trigger conditions.

[0042] In an optional embodiment, the first-level method can also be implemented in other ways, such as through mobile collection equipment and manual input; specifically, the operation and maintenance personnel use mobile monitoring equipment (such as portable vibration detectors, temperature and humidity measuring instruments) to conduct regular inspections at different locations of the wind turbine components to collect data such as environmental conditions, operating status and structural stress; these data can be uploaded to the central processing system through the wireless communication function of the mobile device, or can be added to the system database by manual entry; risk warning data can be identified by manually comparing the test results with preset thresholds, and then subsequent protective measures can be taken as needed; although this method relies on manual operation and has low collection efficiency and accuracy, it can be used as an alternative to meet basic data collection needs in scenarios with specific resources, such as when the wind turbines are more dispersed or the sensor network installation is limited.

[0043] Example 2, reference Figure 1-Figure 2 , is an embodiment of the present invention, which provides a method for protecting a wind turbine from vortex-induced resonance, comprising:

[0044] S2: Based on a type of data, determine and analyze the risk of the unit.

[0045] It should be noted that if Figure 1As shown in S2, judging and analyzing unit risks includes identifying and analyzing potential risk factors in unit operation based on collected data and conducting risk assessment.

[0046] Furthermore, risk assessment includes judging whether there is a potential vortex-induced resonance risk in the current operation of the wind turbine through comprehensive analysis of environmental condition data, unit operating status data, structural monitoring data and historical operating data; changes in environmental condition data, such as drastic fluctuations in wind speed and direction, may cause vortex-induced vibration of the tower; unit operating status data, such as abnormal changes in blade angle, power generation and speed, can be used as a basis for identifying abnormal operating conditions of the wind turbine; structural monitoring data is used to capture abnormal stress and vibration conditions of the tower or blades, providing monitoring support for equipment structural safety; historical operating data can effectively identify deviations and anomalies in long-term operation by comparing the trends of current data with historical data.

[0047] Furthermore, the risk analysis process can be combined with preset risk thresholds to determine the current risk level of the unit by comparing real-time data with the thresholds; for example, vibration amplitude exceeding the threshold may indicate abnormal structural stress; excessive wind speed or sudden changes in wind direction may cause excessive pressure on the wind turbine yaw system; based on the analysis results, the system divides the risk into three levels: low, medium, and high, corresponding to different operational adjustment requirements; in high-risk states, the system can trigger emergency protection measures, such as adjusting the blade angle or forced shutdown; in medium-risk states, the wind turbine operation strategy can be optimized to reduce the impact of vibration or stress; in low-risk states, the current operation strategy is maintained and the changing trend is continuously monitored; it can improve the system's ability to identify potential risks and provide accurate data support for subsequent dynamic adjustment and optimization strategies.

[0048] S3: Dynamically adjust the fan operation strategy.

[0049] It should be noted that if Figure 1 As shown in S3, the dynamic adjustment of the wind turbine operation strategy includes automatic adjustment of the system based on risk assessment to reduce potential risks.

[0050] Furthermore, the dynamic adjustment of the wind turbine operation strategy includes adjusting the yaw angle and blade angle of the wind turbine to change the operating state of the wind turbine, thereby reducing the risk of vortex-induced resonance; when the system detects that the effective value of the tower vibration exceeds a preset threshold (such as 0.025g) and the wind turbine is in a shutdown state, the yaw-to-wind operation is automatically started, and the angle between the cabin and the wind direction is adjusted to keep the wind wheel at a certain free rotation speed, disturb the airflow, and reduce the possibility of vortex generation between the tower and the blades under steady-state airflow conditions.

[0051] Furthermore, if the yaw adjustment cannot completely eliminate the vortex-induced resonance, the system will further adjust the blade angle for optimized operation. Under specific wind speed conditions (such as less than the rated wind speed of 11m / s), the blade angle is gradually adjusted from the parking position (89 degrees) to the specified position (such as 80 degrees), and the interaction between the wind wheel and the airflow is changed through small adjustments to reduce the vibration amplitude; if the wind speed is high (such as more than 11m / s), the blade adjustment amplitude is reduced accordingly (such as adjusted to 85 degrees) to avoid the increase of blade load caused by high wind speed; during the adjustment process, the system monitors the vibration value and other relevant data in real time, and dynamically optimizes the adjustment strategy according to the effect.

[0052] Specifically, during the dynamic adjustment process, when the effective value of the vibration gradually decreases and is lower than the safety threshold (such as 0.005g), the system will maintain the current adjustment state. If the vibration cannot be eliminated after multiple adjustments, the system will take further protective measures, such as keeping some blades at the parking angle while adjusting other blades separately to disperse the vibration force points; through these dynamic adjustment strategies, the system can quickly respond to potential risks and reduce the damage of vortex-induced resonance to the wind turbine structure through precise adjustment.

[0053] Example 3, reference Figure 1-Figure 2 , is an embodiment of the present invention, which provides a method for protecting a wind turbine from vortex-induced resonance, comprising:

[0054] S4: Set thresholds and implement optimization strategies.

[0055] It should be noted that if Figure 1 As shown in S4, the implementation of the optimization strategy includes confirming that adjustment is needed, executing the adjustment according to the preset threshold standard, and optimizing the unit operation effect.

[0056] Further, such as Figure 2 As shown, the adjustment strategies include automatic yaw to wind mode to eliminate the vortex-induced resonance of the tower and adjusting the blade angle mode to eliminate the vortex-induced resonance of the tower; among which, the automatic yaw to wind mode to eliminate the vortex-induced resonance of the tower is specifically as follows: when the wind turbine is in the shutdown state, the wind turbine yaws in real time to face the wind direction, so that the wind wheel can rotate freely at a small speed of less than 400rpm, which can effectively disturb the airflow and avoid vortex excitation of the blades and the tower under long-term steady-state airflow;

[0057] When all of the following conditions are met, the unit starts to perform automatic yaw to eliminate wind vibration; when AB or AC is met, the automatic yaw adjustment action is not performed;

[0058] A. The unit is in shutdown completion state;

[0059] B. The effective value of vibration is greater than the set threshold (0.025g);

[0060] C. The propeller blade angle has reached the normal parking position of 89 degrees;

[0061] The specific process of automatic yaw to eliminate tower vortex-induced vibration in wind is as follows:

[0062] The main control system detects that the angle between the cabin and the wind direction (wind direction deviation) is greater than the positive / less than the negative set threshold, such as 12 degrees. The threshold is adjustable, generally between 10-15 degrees. The threshold can be set and modified externally to send a right / left yaw command and a yaw speed given value to the yaw inverter, and the yaw starts to move. When the main control PLC detects that the angle between the cabin and the wind direction is equal to 0 degrees, the yaw stops.

[0063] Specifically, the cabin angle is measured by the sensor, the wind direction is measured by the wind vane, and the wind direction deviation value is: the cabin angle measurement value minus the wind direction measurement value; if the wind direction deviation value is greater than the set threshold of 12 degrees, it means that the wind vane and the cabin angle are biased to the left of the wind, and the wind turbine yaw system needs to start yaw to the right;

[0064] Similarly, if the wind direction deviation value is less than the set threshold of 12 degrees, it means that the angle between the wind vane and the nacelle is biased to the right of the wind, and the wind turbine yaw system needs to start yaw to the left;

[0065] Furthermore, the blade angle adjustment method is used to eliminate the tower vortex-induced resonance. Specifically, the wind turbine blade angle is adjusted to achieve the tower vortex-induced resonance. The wind turbine is in standby mode, and the blade angle of the unit is at 89 degrees (stop position).

[0066] When all the following conditions are met, the unit starts to adjust the blade angle to eliminate vibration; when AB or AC is met, the vibration-eliminating action of adjusting the blade angle is not performed;

[0067] A. The unit is in shutdown completion state;

[0068] B. The effective value of vibration is greater than the set threshold (0.01g);

[0069] C. The propeller blade angle has reached the normal parking position of 89 degrees;

[0070] D. Automatic yaw to wind is completed or the yaw system fails;

[0071] The specific process of adjusting the blade angle to eliminate the tower vortex-induced vibration is as follows:

[0072] ① When the wind speed is less than the rated wind speed of 11m / s, the three blades open from 89 degrees to 80 degrees at a speed of 1.5 degrees per second;

[0073] When the wind speed is greater than or equal to 11m / s, the three blades open from 89 degrees to 85 degrees at a speed of 1.5 degrees per second;

[0074] ② Maintain the angle in step 1 of the propeller opening and wait for 60 seconds. If the effective value of the vibration is less than 0.005g at this time, maintain the current angle of the three blades;

[0075] ③ In step 2, if the vibration value of the unit still exceeds 0.005g, blades 1 and 3 are kept at the shutdown angle of 89 degrees, and blade 2 is opened from 89 degrees to 0 degrees at a speed of 1.5 degrees per second;

[0076] ④ When the unit starts, the blade adjustment method for vibration elimination is exited, and the three blades return to the shutdown scheduling rate of 89 degrees at a speed of 1.5 degrees per second. After the shutdown is completed, the unit has no faults and meets the automatic power generation operation mode, and the blades start to operate for power generation.

[0077] S5: Continue to monitor and provide feedback to continuously optimize protection effects.

[0078] It should be noted that if Figure 1 As shown in S5, continuously optimizing the protection effect includes tracking, monitoring and feedback analysis of the optimization results during operation, and further adjusting the optimization strategy based on the feedback results.

[0079] Furthermore, the system evaluates the effectiveness of current protection measures by real-time monitoring of multi-dimensional data such as effective vibration value, blade angle, yaw status and environmental conditions; if the monitoring results show that the vibration value has not yet dropped to the safety threshold (such as below 0.005g), the system will re-evaluate whether the current operating strategy needs further adjustment based on the feedback data, such as further optimizing the blade angle or yaw angle, or combining multiple strategies to achieve better protection effect; in addition, the system will record key data after the implementation of the optimization measures, including vibration change trends and system response time, to provide a reference for subsequent analysis and strategy improvement.

[0080] Furthermore, the system establishes a historical operation optimization database by accumulating feedback data, compares the adjustment results under different environmental conditions and operating states with the risk change trend, and gradually improves the optimization strategy; for the same or similar operating conditions, the system can automatically select the optimal adjustment plan based on historical data to shorten the response time and improve protection efficiency; if the feedback results show that certain protection measures are not effective under specific conditions, the system can update the adjustment logic, such as changing the threshold standard or optimizing the adjustment sequence, to ensure more accurate response to complex working conditions; through continuous monitoring and feedback analysis, the system can continuously learn and optimize to achieve long-term stability and high efficiency of wind turbine vortex-induced resonance protection.

[0081] The above is a schematic scheme of a method for protecting a wind turbine from vortex-induced resonance in this embodiment. It should be noted that the technical scheme of the system of the method for protecting a wind turbine from vortex-induced resonance is the same as the technical scheme of the method for protecting a wind turbine from vortex-induced resonance described above.
