[0026] 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 of a method for determining virtual resources in an embodiment of the present application. Figure 1As 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 are shown.

[0027] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for determining virtual resources in the embodiment of the present application. 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.

[0028] A wireless network provided by a communication provider of a computer terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. 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.

[0029] In this embodiment, a method for determining virtual resources is provided, which is applied to the above-mentioned computer terminal. Figure 2 is a flow chart of a method for determining virtual resources according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0030] Step S202, determining a first problem point of the blade according to the deformation of the blade in the wind turbine generator set;

[0031] Step S204, determining a first maintenance plan for the blade according to the first problem point, and determining a first maintenance material required for repairing the blade according to the first maintenance plan;

[0032] Step S206, determining a maintenance map according to the first problem point, the first maintenance plan and the first maintenance material, wherein the maintenance map represents a connection relationship between the first problem point, the first maintenance plan and the first maintenance material, and the maintenance map is used to indicate maintenance virtual resources required to maintain the blade;

[0033] Step S208, determining all virtual resources required for investing in the blade according to the maintenance virtual resources and the equipment virtual resources of the blade, wherein the equipment virtual resources are resources required for manufacturing the blade.

[0034] Through the above steps, the first problem point of the blade is determined according to the deformation of the blade in the wind turbine; the first maintenance plan of the blade is determined according to the first problem point, and the first maintenance material required for repairing the blade is determined according to the first maintenance plan; a maintenance map is determined according to the first problem point, the first maintenance plan and the first maintenance material, wherein the maintenance map represents the connection relationship between the first problem point, the first maintenance plan and the first maintenance material, and the maintenance map is used to indicate the maintenance virtual resources required to maintain the blade; all virtual resources required to invest in the blade are determined according to the maintenance virtual resources and the equipment virtual resources of the blade, wherein the equipment virtual resources are the resources required to manufacture the blade. This solves the problem in the related art that only the equipment cost of the blade is considered, resulting in the investment cost of the blade not being consistent with the actual cost.

[0035] In an exemplary embodiment, determining a first problem point of a blade according to the deformation of the blade in a wind turbine generator includes: obtaining a first picture of the blade at a current moment and a second picture of the blade at a previous moment captured by a radar, wherein the radar is set up on the ground corresponding to the blade; determining that the blade is deformed when the first picture is inconsistent with the second picture; analyzing the amplitude and order frequency of the blade through the deformation of the blade and the operating condition of the wind turbine generator; and determining the first problem point according to the amplitude and the order frequency.

[0036] A high-precision millimeter-wave radar installed on the ground captures the first picture of the blade at the current moment and the second picture at the previous moment. Millimeter-wave radar can penetrate adverse weather conditions such as fog, rain or snow, and provide high-precision image data to ensure reliable detection in various environments. By comparing the first picture with the second picture, it is possible to intuitively identify whether the blade has deformed, especially slight deformations. If inconsistencies are found in the image information, it means that the blade has deformed between the two snapshots. This deformation may be caused by factors such as wind loads, temperature changes, and material aging on the blade. The detection of deformation provides intuitive evidence for subsequent fault diagnosis, but in order to more deeply understand the characteristics and potential impacts of the deformation, the amplitude and order frequency of the deformation need to be further analyzed.

[0037] Amplitude and order frequency are two key parameters that describe the vibration characteristics of blades, and they are closely related to the health of the blades. Through spectral analysis of the deformation image, the amplitude of the blade at different positions and the frequency distribution of the vibration can be accurately measured. The order frequency usually reflects the vibration mode of the blade. Different order frequencies correspond to different vibration forms, which may be related to the inherent properties of the blade (such as material, design) or the external environment (such as wind speed, temperature). Combining the analysis results of the deformation, amplitude and order frequency of the blade, the abnormality of the blade, that is, the first problem point, can be determined.

[0038] In an exemplary embodiment, determining a first maintenance plan for the blade based on the first problem point includes: when there are multiple maintenance plans corresponding to the first problem point, obtaining the maintenance resources required for each of the multiple maintenance plans; and determining the maintenance plan with the least maintenance resources as the first maintenance plan.

[0039] Optionally, assuming that the surface of the blade is slightly damaged, the repair plan includes: Plan A: On-site repair using fast-curing composite materials. Plan B: Remove the damaged blade and send it to a professional repair center for repair. Plan C: Replace the entire blade. A detailed evaluation of the maintenance resources required for each maintenance plan is performed. Plan A requires less manpower, fast-curing composite materials and some special tools, and short downtime. Plan B requires more manpower (including personnel for disassembling and reinstalling the blades), transportation costs, professional repair center fees, and longer downtime. Plan C requires a large amount of manpower and equipment resources, the cost of a brand new blade, transportation and installation costs, and the longest downtime. Based on the evaluation of maintenance resources, all plans are compared to find the plan with the least resource consumption. It should be clear that the least in this embodiment usually refers to the lowest total cost after comprehensively considering all resource consumption. For example, although the material cost of Plan A may be higher than that of Plan B, its manpower cost, downtime loss and total time cost are lower. Overall, Plan A is the plan with the least resource consumption, that is, the first maintenance plan.

[0040] In an exemplary embodiment, determining a first maintenance plan for the blade based on the first problem point includes: when there are multiple maintenance plans corresponding to the first problem point, determining the number of times the multiple maintenance plans have been adopted in the historical stage; and determining the maintenance plan with the largest number of times as the first maintenance plan.

[0041] Optionally, assuming that mild corrosion is detected on the trailing edge of the blade, the maintenance plans include: Plan A: Use a new protective coating for rapid local coverage on site. Plan B: Dismantle the damaged blade and send it to a professional anti-corrosion treatment center for in-depth treatment. Plan C: Replace a new anti-corrosion designed blade. Statistics are made of the number of times each maintenance plan has been adopted for the problem of mild corrosion on the trailing edge of the blade in the historical stage. Statistical results show that Plan A has been adopted 80 times in the past three years. Plan B has been adopted 35 times. Plan C has been adopted 15 times. Based on the statistics of historical data, the maintenance plan that has been adopted the most times is determined as the first maintenance plan. In this embodiment, Plan A is the first maintenance plan.

[0042] In an exemplary embodiment, determining a first maintenance plan for the blade based on the first problem point includes: when there are multiple maintenance plans corresponding to the first problem point, determining the time required for each of the multiple maintenance plans; and determining the maintenance plan with the shortest time as the first maintenance plan.

[0043] Optionally, assuming that tiny cracks are detected on the surface of the blade, the repair plans include: Plan A: Use carbon fiber reinforcement materials locally on the surface of the blade for rapid repair. Plan B: Remove the damaged blade and send it to the laboratory for comprehensive inspection and repair. Plan C: Replace the entire blade and conduct a comprehensive inspection of the new blade. Comparing and analyzing the time required for each repair plan, Plan A only requires a few hours of on-site work time, and the use of fast-curing materials allows the repair to be completed quickly; Plan B requires several days to a week, including the removal, transportation, inspection, repair and reinstallation of the blade; Plan C requires several weeks, which includes the customization of new blades, transportation, replacement, and inspection and commissioning of the entire wind power equipment. Therefore, Plan A, which requires the least time, is selected as the first repair plan.

[0044] In an exemplary embodiment, after determining a maintenance map based on the first problem point, the first maintenance plan and the first maintenance material, the method further includes: in the event that a second problem point occurs on the blade, determining a second maintenance plan for the blade based on the second problem point, and determining a second maintenance material required to repair the blade based on the second maintenance plan, wherein the second problem point is a problem point other than the first problem point; and adding the second problem point, the second maintenance plan and the second maintenance material to the maintenance map to update the maintenance map.

[0045] Use high-precision detection technology and data analysis methods to accurately identify the second problem point on the blade. For example, the first problem point is the peeling of the coating on the blade surface, while the second problem point is the tiny cracks in the internal structure of the blade. Based on the specific situation of the second problem point, combined with the operating environment, material properties and historical maintenance data of the blade, determine the most suitable second maintenance plan. Assuming that the second problem point is a tiny crack in the internal structure of the blade, the second maintenance plan is to locally fill and reinforce the damaged part. Based on the determined second maintenance plan, evaluate and determine the second maintenance materials required to implement this plan. These materials include specific repair materials, tools, equipment and any additional auxiliary resources. For example, if the second maintenance plan chooses to locally fill and reinforce the damaged part, the second maintenance materials include structural adhesive, carbon fiber cloth, etc.

[0046] The information of the second problem point, the second maintenance plan and the second maintenance materials are integrated and added to the existing maintenance atlas to complete the update of the atlas. For example, in the maintenance atlas, a new entry is added to describe "micro cracks in the internal structure of the blade", and the corresponding second maintenance plan "local filling and reinforcement of the damaged part" and the main second maintenance materials required "structural adhesive, carbon fiber cloth, etc." are recorded. This update makes the atlas more comprehensive. When encountering similar second problem points in the future, you can immediately look up the atlas, refer to historical maintenance plans and material preparation experience, and respond quickly.

[0047] In an exemplary embodiment, all virtual resources required for investing in the blade are determined based on the maintenance virtual resources and the equipment virtual resources of the blade, including: obtaining the equipment information of the blade from a knowledge database to determine the equipment virtual resources; integrating the maintenance virtual resources and the equipment virtual resources through preset rules in a cost budget model to obtain all virtual resources.

[0048] Detailed information about the blade and its equipment is extracted from the knowledge database, including the purchase cost, installation cost, daily operating cost, depreciation cost, insurance cost, energy consumption cost, etc. of the equipment. This equipment information forms the basis of the equipment cost and reflects the economic burden of the equipment from purchase to operation. Assume that the knowledge database records that the purchase cost of the blade equipment is 1 million yuan, the installation cost is 200,000 yuan, the annual depreciation cost is 100,000 yuan, the insurance cost is 50,000 yuan / year, as well as energy consumption and other operating costs. By summarizing these data, the equipment cost of the equipment at the current operation stage can be obtained.

[0049] Based on the specific problem points of the blade and the selected maintenance plan, the direct and indirect costs of the maintenance work are evaluated. Direct costs include the purchase of maintenance materials, labor costs, rental costs of maintenance tools and equipment, etc.; indirect costs involve downtime losses, additional energy consumption, and post-repair testing costs. For example, if the blade needs to be partially repaired, the maintenance cost includes: carbon fiber reinforcement material cost of 10,000 yuan, labor costs of 20,000 yuan, downtime losses (based on downtime and power generation income) of 50,000 yuan, and subsequent testing and verification costs of 10,000 yuan.

[0050] The equipment cost and maintenance cost are integrated through the preset rules in the cost budget model to calculate the total cost of the entire project. For example, the cost budget model can integrate costs through the following rules: equipment depreciation expenses are averaged to monthly on an annual basis; operating costs are allocated proportionally to each maintenance operation; maintenance costs and downtime losses are calculated based on actual downtime. Assume that after integration, the total cost calculated by the cost budget model is 1.2 million yuan per year, of which equipment costs are 1.1 million yuan and maintenance costs are 100,000 yuan.

[0051] Through the above process, wind power projects can achieve refined management of equipment costs and maintenance costs, and provide a comprehensive and accurate economic evaluation for project cost control and investment decisions.

[0052] In order to better understand the process of the above-mentioned method for determining virtual resources, the above-mentioned method for determining virtual resources is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0053] Figure 3is a schematic diagram of a method for determining virtual resources according to an embodiment of the present application, such as Figure 3 As shown, specifically including the following:

[0054] The blades of wind turbines are affected by various loads during operation, including wind, gravity, rotational force, etc. These loads cause the blades to deform or vibrate. This embodiment uses high-precision millimeter-wave radar technology to capture subtle changes in the blades in different areas in segments, and construct a three-dimensional deformation image of the entire blade. This image analysis is not only limited to deformation under static conditions, but can also capture the vibration mode of the blades under dynamic conditions, including amplitude and frequency characteristics. Through in-depth analysis of these data, especially in combination with the multi-operating conditions during the operation of the unit, problem points on the blades, such as cracks, distortions or abnormal vibration areas, can be identified.

[0055] Once the problem points on the blades are identified, a series of maintenance plans are developed based on the location and type of the problem points and the specific environment of the wind farm. Different problems require different treatments. For example, small cracks only require local repairs, while large-area damage requires replacement of part or the entire blade. In this embodiment, a correspondence map from problem points to maintenance plans is constructed in advance, and further refined into a list of maintenance materials required for each maintenance plan. This includes repair materials, tools, special equipment, etc. The establishment of the map enables a maintenance budget to be quickly formulated when problems arise, minimizing time and economic costs. The map is not static, but will be updated regularly with maintenance history, technological advances, and cost fluctuations.

[0056] Each maintenance operation will be recorded in the maintenance feature record table to enrich and optimize the knowledge sample library in the atlas. It should be clear that the maintenance feature record table records detailed information about the blade problem, including the time and specific location when the problem first occurred, as well as the meteorological conditions at the time, such as wind speed and humidity. In addition, the brand, model, height, type (such as hybrid tower, steel frame, steel structure blades) of the blade, as well as the terrain characteristics of the wind farm, the type of wind turbine (direct drive or double feed) and the working condition of the transmission chain are also recorded.

[0057] Based on the records of the above maintenance characteristics, a cost calculation model is used in this embodiment to predict the investment cost of different blades, where the investment cost includes the initial equipment cost of the blade and the maintenance cost incurred during the life cycle. The cost calculation model will comprehensively consider factors such as the type of blade, maintenance history, wind farm environment, etc. to predict maintenance problems that may be encountered in the future and their costs. By accurately calculating these costs, an investment return analysis of the blade throughout its life cycle can be obtained, which serves as a reliable basis for investment decisions.

[0058] 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.

[0059] In the present embodiment, a device for determining virtual resources is also provided, and the device is used to implement the above-mentioned embodiment and preferred implementation mode, and the descriptions that have been made are not repeated. As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function. Although the equipment described in the following embodiments is preferably implemented with software, the implementation of hardware, or a combination of software and hardware is also possible and conceived.
