Abstract
Description
Technical Field
[0001] This invention belongs to the field of wind power generation technology, specifically relating to a collaborative control method and system for cluster lubrication of wind turbine generators. Background Technology
[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.
[0003] As a new energy source, wind power has become an important indicator of a low-carbon economy. With the continuous advancement of wind power technology and the expansion of the market, wind power generation faces multiple challenges, including high maintenance costs for large components, declining grid transaction prices, and the increasing demands from grid safety management agencies at all levels to improve the stability of wind power generation and reduce grid impacts. Improving the reliability of wind turbine units, especially large components, increasing wind energy utilization efficiency, and reducing wind power fluctuations have become important directions for the development of wind power technology.
[0004] The widespread application of wind power generation is accompanied by various technological challenges, among which the lubrication control of the yaw and pitch bearings of wind turbine units is a crucial technical issue. Improper lubrication control of yaw and pitch bearings can lead to problems such as grease leakage, poor lubrication, and bearing damage. Maintenance and replacement of yaw and pitch bearings require specialized cranes, resulting in high costs, and excessively long maintenance cycles lead to significant power loss. Furthermore, if bearing damage is not detected and addressed promptly, it can potentially cause safety accidents.
[0005] Therefore, in-depth research on the lubrication control of yaw bearings and pitch bearings of wind turbine units can improve the reliability of unit operation, reduce unit maintenance costs, and enhance the profitability of wind farms. It is one of the important means to promote the continuous development, progress and application of wind power generation technology and improve unit performance, and is of great significance to ensuring the safe, stable and efficient operation of wind turbine units.
[0006] In existing wind turbine lubrication technologies, one approach is to directly activate the lubrication pump to inject grease into the yaw and pitch bearings at certain intervals. However, the yaw and pitch bearings may be stationary during grease injection, preventing the grease from being evenly distributed across the lubrication points due to bearing movement. This leads to grease buildup near the injection port, causing insufficient lubrication in some areas and excessive grease leakage in others. Another approach is to shut down the wind turbine at certain intervals, then restart it to perform yaw and pitch operations, simultaneously activating the lubrication pump to inject grease into the yaw and pitch bearings. This technique ensures even grease distribution within the bearings, guaranteeing effective lubrication. However, factors such as centralized commissioning and grid connection of wind farms, centralized upgrades of wind turbine control systems, and centralized power-on of wind turbines after maintenance result in highly uniform operating times for all wind turbines within the wind farm. Batch shutdowns of wind turbines cause power fluctuations, impacting grid performance. Furthermore, the inability of wind turbines to select shutdown times based on dispatched active power commands leads to power loss and reduced wind farm revenue. Summary of the Invention
[0007] To address the aforementioned issues, this invention proposes a collaborative control method and system for wind turbine cluster lubrication. By identifying lubrication action requirements for each individual wind turbine, and combining these requirements with the collaborative control and management of lubrication actions for all wind turbines in the wind turbine cluster, the method prioritizes ensuring the power generation needs of the wind farm while simultaneously meeting the lubrication requirements of the wind turbines. This ensures that the active power fluctuations of the wind farm meet the grid requirements, reduces power loss due to lubrication actions, lowers maintenance costs, and improves the reliability and economy of wind turbine operation.

[0026] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.
[0027] Example 1 Embodiment 1 of this invention introduces a collaborative control method for cluster lubrication of wind turbine units.
[0028] like Figure 1 The method for coordinated control of cluster lubrication of wind turbine units, as shown, includes: Obtain the interval time of the fan lubrication action; Calculate the current time of the fan and the duration of the last lubrication action, and determine whether the fan needs lubrication based on the interval and duration; When a fan requires lubrication, a lubrication fan queue is established. Based on the current operating status and power generation of the wind turbine units, and according to the constructed lubrication wind turbine queue, the lubrication action requirements of different wind turbines in the wind turbine units are controlled to complete the coordinated control of wind turbine cluster lubrication.
[0029] It should be noted that the wind turbine lubrication in this embodiment includes at least yaw bearing lubrication and pitch bearing lubrication.
[0030] In this embodiment, when the wind turbine requires lubrication and is in standby mode, or when the wind turbine is yawing and untying the cable and the cable twist angle is greater than a preset angle or the predicted wind speed is less than the wind turbine's cut-in wind speed, the wind turbines in the wind turbine are controlled to perform lubrication actions sequentially according to the constructed lubrication turbine queue, thereby achieving cluster lubrication control of the wind turbines. When the wind turbine requires lubrication and is not in standby mode, the maximum number of wind turbines that can be shut down is determined based on the power generation. Combined with the constructed lubrication turbine queue and the real-time wind speed of the turbine, the wind turbines in the wind turbine are controlled to perform lubrication actions sequentially, thereby achieving cluster lubrication control of the wind turbines.
[0031] This embodiment uses, as follows: Figure 4 The interval between fan lubrication actions is obtained by this method, based on the annual grease injection volume of the fan components (generally 40). kg ~50 kg The number of lubrication actions required per year is calculated based on the grease output of the grease pump and the amount of grease dispensed per lubrication operation. This yields the interval between two fan lubrication operations (where T1 represents the minimum interval between two fan lubrication operations, T2 represents the time from the completion of grease lubrication to the start of cable unwinding, T3 represents the working time of one grease injection during the lubrication operation, T4 represents the random time between T3 and T5, and T5 represents the maximum interval between two fan lubrication operations) and the duration of a single fan lubrication operation.
[0032] In this embodiment, the need for lubrication of the fan is determined by comparing the relationship between the time interval and the duration. If the duration is less than the time interval, the fan does not require lubrication; otherwise, lubrication is required. (1) If the duration is less than the interval time T1, the wind turbine has no lubrication requirement; (2) If the duration is greater than the interval time T1 and less than the interval time T2, the wind turbine generally requires lubrication. (3) If the duration is greater than the interval time T2, the wind turbine unit will require strong lubrication action.
[0033] As one or more implementation methods, in this embodiment, after obtaining the lubrication requirement, the wind turbine determines the next action of the wind turbine based on the current state of the wind turbine: If the wind turbine is performing a yaw uncoupling operation and the cable twist angle is greater than the preset angle P, the lubrication operation will be executed immediately and the system will enter a waiting state. If the wind turbine requires general lubrication and is in standby mode, the wind turbine will issue a lubrication request and perform the lubrication action after approval. If the wind turbine requires lubrication, a lubrication request is submitted to the field control system, and the lubrication action is carried out after approval.
[0034] As one or more implementation methods, in this embodiment, after the wind turbine requests a lubrication action, such as Figure 7 As shown, a lubrication fan queue is established according to time sequence. Based on control requirements, it is determined whether to approve the lubrication action request of the wind turbine unit. Specifically: If a wind turbine is in standby mode in the queue and the predicted wind speed is less than the cut-in wind speed V1 within time T3, the wind turbine lubrication action request is approved and the turbine queue is updated; otherwise, proceed to the next step. Based on the dispatch active power command and the available power of the units, calculate the maximum number of units that can be shut down without causing power loss, approve the lubrication needs of some units, and update the unit queue; If the wind turbine's arrival time is greater than T4, the average wind speed of the wind turbine is less than V2, and the number of turbines currently performing lubrication is less than the maximum number of turbines that can be shut down. n Approved the application for lubrication of wind turbine units and updated the unit queue; If the wind turbine's entry time is greater than T5 and the number of turbines currently performing lubrication actions is less than n, the wind turbine lubrication action application is approved, and the turbine queue is updated. Determine if the crew queue is empty. If it is empty, the current request processing ends; otherwise, proceed to the next cycle.
[0035] It should be noted that this embodiment classifies the lubrication needs of wind turbines based on time intervals. From the perspective of a single wind turbine, lubrication is prioritized during standby to reduce power loss due to turbine shutdown. From the perspective of the entire wind turbine system, lubrication needs are centrally processed for each turbine. The active power of the wind farm is prioritized for approval of wind turbine lubrication needs in batches when tracking dispatch instructions, preventing power loss due to lubrication and avoiding abnormal power fluctuations caused by multiple wind turbines shutting down simultaneously for lubrication, which would affect dispatch assessments. At the same time, lubrication needs are classified and controlled according to the wind turbine's arrival time to avoid the risk of insufficient lubrication and component failure due to long-term unresponsive lubrication needs.
[0036] like Figure 5 , Figure 6 and Figure 8 As shown, in the coordinated control of wind turbine cluster lubrication in this embodiment, the wind turbine queue is constructed according to the order in which the wind turbines submit their lubrication requests, based on the wind turbines' lubrication shutdown requests. This results in a lubrication wind turbine queue. The predicted wind speed within the lubrication operation time is predicted based on the environment of the wind turbine. This predicted wind speed is compared with the minimum wind speed required for power generation (i.e., the cut-in wind speed V1). If the predicted wind speed is lower than the cut-in wind speed, it indicates that the predicted wind speed has not reached the wind turbine's power generation speed, and the wind turbine is in a shutdown state. The lubrication request is then directly approved, and the constructed lubrication wind turbine queue is cleared after the wind turbine completes the lubrication operation. If the predicted wind speed is not lower than the cut-in wind speed, it indicates that the wind turbine is in a power generation state. The maximum number of wind turbines that can be shut down is determined by considering the relationship between the wind turbine's power generation and the grid dispatch command, ensuring that the number of wind turbines performing lubrication during each shutdown does not exceed the determined maximum number. When the lubrication waiting time exceeds the maximum interval T5, the wind turbine lubrication operation is executed sequentially based on the constructed lubrication turbine queue.
[0037] It should be noted that when the number of fans requesting lubrication exceeds the maximum number of fans that can be stopped, the fans requesting lubrication will be stopped simultaneously according to the maximum number of fans that can be stopped, based on the constructed lubrication fan queue. When the number of fans requesting lubrication does not exceed the maximum number of fans that can be stopped, the fans requesting lubrication can be stopped one by one to perform the lubrication, or the fans requesting lubrication can be stopped simultaneously to perform the lubrication.
[0038] It should be noted that wind speed forecasting and grid dispatch command generation are existing technologies that should be known to those skilled in the art, and can be achieved using methods such as... Figure 2 and Figure 3 The flowchart shown is now complete.
[0039] This embodiment identifies lubrication needs for a single wind turbine and coordinates the lubrication actions of all wind turbines in the wind turbine unit based on these needs. It prioritizes the power generation needs of the wind farm while meeting the lubrication requirements of the wind turbine units, ensuring that the active power fluctuations of the wind farm meet the grid requirements, reducing power loss caused by lubrication actions, lowering maintenance costs, and improving the reliability and economy of wind turbine unit operation.
