[0027] The method embodiments provided in the embodiments of the present application can be executed in a computer terminal or a similar computing device. Taking running on a computer terminal as an example, Figure 1 1 is a hardware structure block diagram of a computer terminal for determining an operation and maintenance strategy according to an embodiment of the present application. Figure 1 As shown, the computer terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor (Central Processing Unit, MCU) or a programmable logic device (Field Programmable Gate Array, FPGA)) and a memory 104 for storing data, wherein the above-mentioned computer terminal may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the computer terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0029] A wireless network provided by a communication provider of a computer terminal.

In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0030] In this embodiment, a method for determining an operation and maintenance strategy is provided, which is applied to the above-mentioned computer terminal. Figure 2 is a flow chart of a method for determining an operation and maintenance strategy according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0031] Step S202, constructing wind turbine operation and maintenance indicators for the wind power generation equipment, wherein the wind turbine operation and maintenance indicators include: equipment performance parameter indicators, monitoring indicators for the wind power generation equipment, and state prediction indicators for the wind power generation equipment;

[0032] Step S204, creating a correspondence between the index parameters of the wind turbine operation and maintenance index and the operation and maintenance strategy of the wind power generation equipment;

[0033] Step S206, when the target wind power generation equipment is in a state requiring operation and maintenance, obtain the target indicator parameters corresponding to the wind turbine operation and maintenance indicators of the target wind power generation equipment, and determine the target operation and maintenance strategy of the target wind power generation equipment according to the target indicator parameters and the corresponding relationship.

[0034] Through the above steps, wind turbine operation and maintenance indicators are constructed for wind power generation equipment, wherein the wind turbine operation and maintenance indicators include: equipment performance parameter indicators, monitoring indicators for the wind power generation equipment, and state prediction indicators for the wind power generation equipment; create a correspondence between the indicator parameters of the wind turbine operation and maintenance indicators and the operation and maintenance strategy of the wind power generation equipment; when the target wind power generation equipment is in a state where operation and maintenance is required, obtain the target indicator parameters corresponding to the wind turbine operation and maintenance indicators of the target wind power generation equipment, and determine the target operation and maintenance strategy of the target wind power generation equipment according to the target indicator parameters and the corresponding relationship. This solves the problem in the related art that the operation and maintenance strategy cannot be accurately determined when the wind power generation equipment needs operation and maintenance.

[0035] In an exemplary embodiment, constructing wind turbine operation and maintenance indicators for wind power generation equipment includes: constructing the equipment performance parameter indicators for the wind power generation equipment to characterize the basic operating status of the wind power generation equipment, constructing the monitoring indicators for the wind power generation equipment to characterize the current health status of the wind power generation equipment, and constructing the status prediction indicators for the wind power generation equipment to characterize the predicted usage status of the wind power generation equipment.

[0036] For wind power generation equipment, equipment performance parameter indicators include power generation efficiency, rotation speed, vibration amplitude, etc. These data can be used to understand whether the wind power generation equipment is working properly. For example, if the power generation efficiency of the wind power generation equipment suddenly drops, it means that the blades are damaged or there is a problem with the transmission system. Monitoring indicators include real-time environmental data such as temperature, humidity, wind speed, wind direction, and operating data such as vibration, sound, and power output of wind power generation equipment. Through these data, the health status of wind power generation equipment can be monitored in real time. For example, if the vibration of the wind power generation equipment is abnormally increased, it means that there is a fault inside the equipment and immediate attention is required. The state prediction indicator is based on historical data and current monitoring data, and uses artificial intelligence algorithms to predict the operating status of wind power generation equipment in the future. For example, if it is predicted that the wind speed will drop significantly in the future, which may affect the power generation efficiency, the working mode of the wind power generation equipment can be adjusted in advance, or maintenance can be planned to reduce the loss of power generation.

[0037] In an exemplary embodiment, after determining the target operation and maintenance strategy of the target wind power generation equipment according to the target indicator parameters and the corresponding relationship, the method also includes: when there are multiple target operation and maintenance strategies, determining the number of times the multiple target operation and maintenance strategies are adopted; pushing the target operation and maintenance strategy with the largest number of times to the mobile terminal of the target object to instruct the target object to operate and maintain the target wind power generation equipment according to the target operation and maintenance strategy with the largest number of times.

[0038] Optionally, when the rotation speed of the blades of the wind power generation equipment decreases abnormally, the following operation and maintenance strategies may be used: A. Check whether the blades are damaged or iced. If so, clean or replace them immediately. B. Check whether the transmission system of the wind power generation equipment is faulty. If so, repair it. C. Check whether the wind speed sensor is working properly. If abnormal, calibrate or replace it. D. Adjust the power generation plan, reduce the load of the wind power generation equipment, and observe whether the rotation speed of the blades is restored.

[0039] In actual operation, strategy A is adopted the most times, which means that when the blade rotation speed decreases abnormally, checking whether the blade is damaged or iced, and cleaning or replacing it is usually the fastest and most effective solution. Therefore, when the wind power generation equipment has an abnormal decrease in blade rotation speed again, strategy A will be pushed to the mobile terminal of the target object responsible for maintaining the wind power generation equipment as the preferred operation and maintenance strategy. After receiving this suggestion, the target object can directly maintain the equipment according to strategy A, avoiding long-term shutdown of the wind power generation equipment and ensuring the normal supply of electricity.

[0040] In an exemplary embodiment, after determining the target operation and maintenance strategy of the target wind power generation equipment according to the target indicator parameters and the corresponding relationship, the method also includes: when there are multiple target operation and maintenance strategies, obtaining the operation and maintenance resources required for each target operation and maintenance strategy; determining the target operation and maintenance strategy corresponding to the target operation and maintenance resource whose operation and maintenance resources are less than the currently configured resources; and pushing the target operation and maintenance strategy corresponding to the target operation and maintenance resource to the mobile terminal of the target object to instruct the target object to operate and maintain the target wind power generation equipment according to the target operation and maintenance strategy corresponding to the target operation and maintenance resource.

[0041] Optionally, when the oil quality of wind power generation equipment deteriorates, the following operation and maintenance strategies can be used: A. Immediately dispatch professional maintenance personnel to replace the oil, which requires professional personnel, special tools and a large amount of new oil. B. Use online oil monitoring equipment to conduct detailed inspections. If it is confirmed that the oil quality has indeed deteriorated to the point where it needs to be replaced, then replace it. This requires online monitoring equipment and a small amount of new oil. C. Adjust the power generation plan, reduce the equipment load, and observe whether the oil quality can recover naturally. This mainly requires adjusting the power generation plan and requires fewer resources. D. Make an appointment for future regular maintenance and replace the oil. This requires reserving maintenance time and has moderate resource requirements.

[0042] In this case, strategy B will be limitedly selected because the resources required by strategy B (i.e., online monitoring equipment and a small amount of new oil) are within the currently configured resource range, while strategy A is effective, but it requires a large amount of new oil and professionals, which exceeds the current resource limit. Therefore, strategy B will be pushed to the mobile terminal of the target object responsible for maintaining wind power generation equipment. After receiving this suggestion, the target object can directly follow strategy B to effectively maintain the equipment with existing resources and avoid equipment downtime due to oil quality problems. At the same time, this method also avoids waste of resources and improves operation and maintenance efficiency.

[0043] In an exemplary embodiment, after determining the target operation and maintenance strategy of the target wind power generation equipment according to the target indicator parameters and the corresponding relationship, the method also includes: when there are multiple target operation and maintenance strategies, obtaining the most recent execution time of each target operation and maintenance strategy; determining the target operation and maintenance strategy corresponding to the target execution time whose execution time is the shortest from the current time; and pushing the target operation and maintenance strategy corresponding to the target execution time to the mobile terminal of the target object to instruct the target object to operate and maintain the target wind power generation equipment according to the target operation and maintenance strategy corresponding to the target execution time.

[0044] Optionally, assume that there are several operation and maintenance strategies: A. Send professionals to inspect and adjust the blade angle on site to restore the normal rotation speed. B. Use online monitoring tools to detect the quality of the oil, and replace or add oil according to the test results. C. Check the tower foundation and reinforce it if necessary to correct the tilt of the tower. Assume that the most recent execution time of these three strategies is: strategy A was executed two days ago, strategy B was executed a week ago, and strategy C was executed a month ago. Considering that the operation and maintenance of wind power generation equipment requires timeliness to prevent potential problems from worsening or causing equipment downtime, strategy A is determined to be the operation and maintenance strategy with the shortest execution time from the current time. Push strategy A to the mobile terminal of the target object responsible for maintaining this wind power generation equipment, instructing the target object to prioritize operation and maintenance according to strategy A to ensure the normal operation of the wind power generation equipment.

[0045] In an exemplary embodiment, after determining the target operation and maintenance strategy of the target wind power generation equipment according to the target indicator parameters and the corresponding relationship, the method also includes: when there are multiple target operation and maintenance strategies, obtaining the pre-configured priority of each target operation and maintenance strategy; determining the target operation and maintenance strategy with the highest priority; pushing the target operation and maintenance strategy with the highest priority to the mobile terminal of the target object to instruct the target object to operate and maintain the target wind power generation equipment according to the target operation and maintenance strategy with the highest priority.

[0046] Alternatively, taking the oil system failure of a wind power generation equipment as an example, assuming that the metal particle content in the oil is abnormal, if it is not handled in time, it will cause the oil system to fail, thereby affecting the operation of the entire wind power generation equipment. In this case, there are several operation and maintenance strategies: A. Immediately dispatch professional maintenance personnel to the site to conduct a comprehensive inspection and replacement of the oil system. B. Monitor the operating status of the oil system online, and take immediate action if the situation deteriorates. C. Adjust the operation plan of the wind power generation equipment, reduce the load, and observe whether the oil system can recover on its own. Assuming that among the priorities of these three strategies, strategy A has the highest priority, strategy B has a high priority, and strategy C has a medium priority, then strategy A will be pushed to the mobile terminal of the target object responsible for maintaining the wind power generation equipment, instructing the target object to immediately dispatch professionals to the site to conduct a comprehensive inspection and replacement of the oil system to solve the current oil system problem.

[0047] In an exemplary embodiment, after pushing the target operation and maintenance strategy with the highest priority to the mobile terminal of the target object to instruct the target object to operate and maintain the target wind power generation equipment according to the target operation and maintenance strategy with the highest priority, the method further includes: when the operating state of the target wind power generation equipment is still in the state requiring operation and maintenance, pushing the target operation and maintenance strategy with the second highest priority to the mobile terminal of the target object to instruct the target object to operate and maintain the target wind power generation equipment according to the target operation and maintenance strategy with the second highest priority.

[0048] Optionally, there are several operation and maintenance strategies for oil system failures of wind power generation equipment: A. Immediately dispatch professional maintenance personnel to the site to conduct a comprehensive inspection and replacement of the oil system. B. Monitor the operating status of the oil system online, and take immediate action if the situation worsens. C. Adjust the operating plan of the wind power generation equipment, reduce the load, and observe whether the oil system can recover on its own. Assume that among the three strategies, strategy A has the highest priority, strategy B has a high priority, and strategy C has a medium priority. After selecting strategy A to operate and maintain the wind power generation equipment, if the operating status of the wind power generation equipment is still in a state where operation and maintenance is required, strategy B is pushed to the mobile terminal of the target object to instruct the target object to operate and maintain the wind power generation equipment according to strategy B.

[0049] In order to better understand the process of the above-mentioned operation and maintenance strategy determination method, the above-mentioned operation and maintenance strategy determination method is described below in combination with an optional embodiment, but is not used to limit the technical solution of the embodiment of the present application.

[0050] Figure 3 is a schematic diagram of a method for determining an operation and maintenance strategy according to an embodiment of the present application, such as Figure 3 As shown, specifically including the following:

[0051] The RCM system of new energy wind power generation equipment mainly includes building a wind turbine operation and maintenance indicator system, creating an RCM model library, data collection and analysis, and formulating maintenance strategies. Among them:

[0052] Constructing a wind turbine operation and maintenance indicator system: The wind turbine operation and maintenance indicator system is the foundation of the entire new energy wind power generation equipment RCM system. It is a multi-dimensional, comprehensive and targeted indicator framework used to evaluate the health status and maintenance needs of wind power generation equipment. The wind turbine operation and maintenance indicator system includes the following key aspects: Equipment performance parameters: such as power output, efficiency, speed, etc., to reflect the normal working status and performance of wind power generation equipment. Equipment monitoring indicators: Covering a variety of sensor data such as sound, vibration, temperature, humidity, etc., used to monitor the operating status of wind power generation equipment in real time. State prediction indicators: Based on historical data and machine learning algorithms, predict the possible future status of wind power generation equipment, such as predicting the remaining life or failure probability of wind power generation equipment. Fault level: According to the nature, frequency and potential impact of the fault of wind power generation equipment, the fault is classified into different levels, such as minor, moderate, severe, etc., to quickly identify faults that need to be handled first. Maintenance strategy: According to different fault levels and predicted states, formulate corresponding maintenance or inspection plans, including preventive maintenance, corrective maintenance and predictive maintenance.

[0053] Create an RCM model library: The reliability-centered maintenance (RCM) model library is the core of the RCM system of new energy wind power generation equipment. By combining the above-mentioned wind turbine operation and maintenance indicator system with real-time monitoring data, a series of causal assumptions are established to analyze the logical relationship between the performance, environmental factors, operating conditions, etc. of wind power generation equipment and equipment failures. The setting of model parameters includes: intervention effect coefficient, which is used to measure the degree of influence of specific maintenance actions on the health status of wind power generation equipment. Potential result distribution, which is used to analyze the range and probability of possible results of maintenance actions based on historical data and model predictions. The verification and adjustment of the model is to ensure the accuracy and reliability of the model by comparing the model prediction results with the actual operating data of wind power generation equipment, and adjust the parameters when necessary to improve the prediction accuracy.

[0054] Data collection and analysis: The RCM system of new energy wind power generation equipment collects the operating data of wind power generation equipment in real time through the intelligent sensor network, including blade vibration, transmission chain wear, oil quality, bearing health, tower inclination, steel strand tension, etc., to achieve all-round monitoring of wind power generation equipment. These data are integrated with meteorological environment data, power generation technology data and historical operation data of wind power generation equipment to form a comprehensive data set, which is then imported into the RCM model for in-depth analysis to identify the health status and potential failure modes of wind power generation equipment.

[0055] Formulate maintenance strategies: Based on the analysis results of the RCM model, the RCM system of renewable energy wind power generation equipment formulates maintenance strategies for different fault scenarios of each wind power generation equipment. These strategies take into account the current power generation plan, the availability of maintenance resources, and the impact of the failure on power generation. For example: If the equipment failure is not urgent and the recent power generation demand is large, the RCM system of renewable energy wind power generation equipment may recommend postponing maintenance to avoid affecting the power generation plan. If the predicted failure will seriously affect the subsequent power generation plan, the RCM system of renewable energy wind power generation equipment will recommend early maintenance to reduce the loss of power generation.

[0056] In this way, the system can flexibly adjust the maintenance plan to ensure that when maintenance resources are limited, the issues that have the greatest impact on power generation efficiency are prioritized, thereby improving the operational reliability and economic benefits of the equipment. The entire process is like an automated decision-making center that intelligently makes the best maintenance decisions based on the actual status and operational needs of wind power equipment.

[0057] Obviously, the above-described embodiments are only part of the embodiments of the present application, not all of the embodiments. In order to better understand the above-mentioned method for determining the operation and maintenance strategy, the above-mentioned process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present application, specifically:

[0058] In an optional embodiment, in combination Figure 4 The method for determining the operation and maintenance strategy of this application is further explained. Figure 4 As shown, including the following:

[0059] Construct a multi-dimensional, comprehensive and targeted operation and maintenance indicator system for wind turbines, which includes wind turbine equipment performance parameters, wind power equipment monitoring indicators, wind power equipment status prediction indicators, wind power equipment fault levels, wind power equipment maintenance strategies, etc. At the same time, various intelligent sensor devices are used to collect and monitor wind turbine generator sets, and meteorological environment data, power generation technology data, equipment historical operation data and real-time monitoring data are integrated.

[0060] The RCM model is constructed based on the wind turbine operation and maintenance indicator system and fused data, including: establishing causal assumptions based on the wind turbine operation and maintenance indicator system and fused data, and clarifying the logical relationship between fused data and potential results. The parameters of the RCM model are set according to data characteristics and causal assumptions, such as intervention effect coefficient, potential result distribution, etc. The RCM model is verified using historical data of wind power equipment operation to check the consistency between the RCM model prediction results and actual data, and adjustments are made as needed.

[0061] After the RCM model training is completed, the fused data is imported into the RCM model for analysis. The maintenance strategy is formulated through fixed thresholds, adaptive thresholds, trend increase warnings, and multi-level evaluations. According to the analysis results generated by the RCM model, maintenance plans are formulated for failures in different equipment and different scenarios. And adjustments are made according to the power generation plan and maintenance plan. If the equipment failure is not urgent and the recent power generation demand is large, the maintenance will be postponed. If the equipment predicts that the failure will affect the subsequent power generation plan, it will be repaired in advance. The best maintenance time is determined based on the equipment's prediction and fault level defects to reduce power generation losses.

[0062] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.

[0063] In this embodiment, a device for determining an operation and maintenance strategy is also provided, which is used to implement the above-mentioned embodiments and preferred implementation modes, and will not be repeated hereafter. As used below, the term "module" may be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0064] Figure 5 : is a structural block diagram of a device for determining an operation and maintenance strategy according to an embodiment of the present application, the device comprising:

[0065] A construction module 50 is used to construct a wind turbine operation and maintenance index for the wind power generation equipment, wherein the wind turbine operation and maintenance index includes: an equipment performance parameter index, a monitoring index for the wind power generation equipment, and a state prediction index for the wind power generation equipment;
