Wind power generation technology is one of the technologies that has developed rapidly in recent years. Due to its abundant energy and high utilization rate, it has a good development prospect.

[0003] Wind turbines are often laid out according to the terrain and wind distribution. The directions of each wind turbine may not be exactly the same, but they will rotate with the wind, which is then converted into electrical energy, transmitted and stored. However, in the design of wind turbines, wind power cables need to be installed on the high towers of wind turbines due to their own working requirements, and they also need to communicate and control. Therefore, in order to improve the efficiency of cable installation and reduce the burden of operation and maintenance, how to carry out integrated design can effectively reduce the hardware cost of wind power generation and the difficulty of cable installation, while also meeting the use requirements of wind turbines, is a technical problem that needs to be solved in this field.

[0045] Embodiment 1

[0046] Figure 1 is a schematic structural diagram of the integrated R & D design device for wind power generation cables provided by Embodiment 1 of this application. As Figure 1 shown, the device includes:

[0047] An information acquisition module 110 is configured to acquire basic parameter information and environmental parameter information of a wind turbine; wherein, the basic parameter information includes at least one of power rating, tower height, and communication requirement information; the environmental parameter information includes at least one of the operating environmental wind parameters, sunlight parameters, and rainfall parameters of the wind turbine.

[0048] A feasibility evaluation module 120 is configured to determine whether the power transmission function, signal control function, and optical fiber communication function of the wind turbine have integration feasibility according to the basic parameter information and the environmental parameter information.

[0049] An integrated design module 130 is configured to, when integration feasibility exists, input the basic parameter information and the environmental parameter information into a cable integrated design model, and determine design data of an integrated cable according to the output result of the cable integrated design model; wherein, the design data includes segment length, insulation layer thickness, shielding layer material, and cable core winding method.

[0050] A wind turbine can be a device that converts wind energy into electrical energy, and is composed of multiple parts such as a wind wheel, a generator, and a tower. It captures wind energy through the wind wheel, drives the generator to rotate and generate electricity, and is supported by the tower to a certain height to obtain better wind energy resources.

[0051] The basic parameter information can be the basic characteristic data on which the operation of the wind turbine depends, and these data play a key role in subsequent analysis and design. It can include: Power rating, which is an index of the power generation capacity of the wind turbine, reflecting the electric power that the unit can output under specific working conditions, usually in kilowatts (kW) or megawatts (MW), and can be specifically monitored in real time through an intelligent power sensor, combined with blockchain technology to ensure the integrity of the data. Tower height, which is the vertical height of the tower of the wind turbine, affects the wind energy capture efficiency and the cable laying length, etc., and can specifically adopt the technology of fusing lidar and vision, using lidar to obtain high-precision distance information and visual images to supplement texture information to accurately measure the tower height. Communication requirement information can be the conditions and requirements involved in the communication between the wind turbine and external systems or internal components, such as communication bandwidth, data transmission rate, and communication protocol, etc. It can be obtained through protocol parsing and traffic analysis of the communication link, and at the same time, intelligent protocol automatic recognition technology is used to adapt to different communication protocols.

[0052] Environmental parameter information, which can be data reflecting the environmental conditions where the wind turbine operates, has an important impact on cable design and system stability. Specifically, it can include: operating environment wind parameters, such as wind speed, wind direction, and wind shear data, which reflect the changes in wind power at different heights and times. Through multi-source wind data fusion technology, combining local high-precision sensors and regional meteorological data, high-resolution wind datasets are generated using data assimilation. Sunshine parameters, such as solar radiation intensity, sunshine duration, and spectral distribution information, affect cable material aging and thermal performance. Specifically, multi-spectral sunshine sensors can be used to accurately measure different spectral components, and combined with drone photography and image processing to analyze sunshine and shadow conditions. Rainfall parameters, such as rainfall intensity, raindrop size distribution, and rainfall duration data, affect the electrical performance and mechanical stability of the cable. A laser disdrometer is used to measure the raindrop spectrum, and combined with a weather radar to obtain regional rainfall dynamic information.

[0053] For various parameter information in this solution, physical quantities can be sensed by intelligent sensors and converted into electrical signals, which are then transmitted to the information acquisition module after signal processing and digitization; or data can be received and parsed by establishing a communication connection with other systems.

[0054] The feasibility evaluation module 120 can be used to analyze and judge whether it is feasible to conduct an integrated design of various cables of the wind turbine under given conditions.

[0055] The power transmission function can refer to the ability to efficiently and stably transmit the electric energy generated by the wind turbine to the power grid or other electrical equipment, which involves aspects such as cable current-carrying capacity, voltage drop, and thermal stability.

[0056] The signal control function can be responsible for signal transmission and control between various components inside the wind turbine and with the external control system to ensure the normal operation of the unit, including requirements such as signal accuracy, timeliness, and anti-interference ability.

[0057] The fiber optic communication function can be a function of using optical fiber as a transmission medium for data communication, which has advantages such as high bandwidth, low loss, and anti-electromagnetic interference, and is used to transmit a large amount of data and control signals in the wind turbine.

[0058] Based on the data obtained in the early stage, this solution judges the integration feasibility of the wind power cables with different functions of the wind turbine, avoiding integrated design under conditions that are not available. Although it saves resources, it will affect the normal operation of the wind turbine.

[0059] The integrated design module 130 can be used to conduct cable integrated design.

[0060] Among them, the cable integrated design model is a mathematical model that can be constructed based on the principle of multi-physical field coupling. It comprehensively considers the influence of factors such as electric field, magnetic field, thermal field, and mechanical field on the cable performance, simulates various physical processes of the cable during actual operation, and optimizes the cable design.

[0061] The integrated cable is a cable that integrates functions such as power transmission, signal control, and optical fiber communication, and improves the compactness of the system through optimized design. Design data maliciously refers to the specific parameters used to guide the production and manufacturing of the integrated cable. The segment length can be the cable segment length determined according to factors such as the cable laying environment and mechanical performance requirements, which helps to improve the cable laying efficiency and maintenance convenience.

[0062] The insulation layer thickness is the thickness of the cable insulation layer, which affects the electrical insulation performance and heat dissipation performance of the cable. It needs to be optimized by comprehensively considering factors such as electric field distribution and heat conduction.

[0063] The shielding layer material is a material used to shield electromagnetic interference, and its performance affects the stability of signal transmission and anti-interference ability. For example, a new type of nanocomposite material is used to improve the shielding effect.

[0064] The cable core winding method can be the winding form of the internal cable core. The cable core winding method affects the mechanical strength, flexibility, and electromagnetic performance of the cable, and the comprehensive performance of the cable can be improved by optimizing the winding method.

[0065] This solution can import the basic parameter information and environmental parameter information into the cable integrated design model as the initial data for model calculation and analysis, and extract and clarify the various design data of the integrated cable from the output results of the cable integrated design model.

[0066] The technical solution provided in this embodiment comprehensively collects the basic and environmental parameter information of the wind turbine through the information acquisition module, judges the feasibility of the wind power cable integration, and finally determines the design data of the integrated cable based on the evaluation results and the model. This solution can design an integrated cable that meets the long-term stable operation requirements of the wind turbine in a complex environment, improve the cable erection efficiency, reduce the operation and maintenance burden, and effectively reduce the hardware cost of wind power and the cable erection difficulty.

[0067] Embodiment 2

[0068] Based on the above embodiment, this embodiment is further optimized. Specifically, the optimization is as follows: The information acquisition module includes: a basic parameter information acquisition unit, which is used to connect to the unit control system through a preset interface, establish a communication link with the unit control system through a standard communication protocol, and read the basic parameter information of the wind turbine; an environmental parameter information acquisition unit, which is used to obtain the installation location of the wind turbine and retrieve the historical environmental parameters of the current installation location. Among them, the historical environmental parameters include the annual wind level, wind distribution months, and wind extreme values at the current installation location, the annual cumulative sunshine duration, sunshine extreme values, as well as the annual rainfall distribution months and rainfall extreme values per unit time. Figure 2 It is a schematic structural diagram of an integrated R & D design device for a wind power cable provided in Embodiment 2 of this application. As Figure 2 shown, the device includes:

[0069] An information acquisition module 210, which is used to acquire the basic parameter information and environmental parameter information of the wind turbine. Among them, the basic parameter information includes at least one of the power level, tower height, and communication requirement information; the environmental parameter information includes at least one of the operating environment wind parameters, sunshine parameters, and rainfall parameters of the wind turbine.

[0070] A feasibility evaluation module 220, which is used to determine whether the power transmission function, signal control function, and optical fiber communication function of the wind turbine have integration feasibility according to the basic parameter information and the environmental parameter information.

[0071] An integrated design module 230, which is used to input the basic parameter information and the environmental parameter information into the cable integrated design model when the integration feasibility is available, and determine the design data of the integrated cable according to the output result of the cable integrated design model. Among them, the design data includes the segment length, insulation layer thickness, shielding layer material, and cable core winding method.

[0072] Among them, the information acquisition module 210 includes:

[0073] A basic parameter information acquisition unit 211, which is used to connect to the unit control system through a preset interface, establish a communication link with the unit control system through a standard communication protocol, and read the basic parameter information of the wind turbine;

[0074] An environmental parameter information acquisition unit 212, which is used to obtain the installation location of the wind turbine and retrieve the historical environmental parameters of the current installation location. Among them, the historical environmental parameters include the annual wind level, wind distribution months, and wind extreme values at the current installation location, the annual cumulative sunshine duration, sunshine extreme values, as well as the annual rainfall distribution months and rainfall extreme values per unit time.

[0075] A preset interface can be a pre - set channel for connecting different devices or systems, which stipulates the physical and logical characteristics of the connection. In this scenario, it is an interface specifically set up for connecting the unit control system to ensure accurate docking between the information acquisition unit and the unit control system. For example, a standardized industrial interface such as an RJ45 Ethernet interface may be used for network communication connection, and at the same time, specific electrical isolation and signal conversion circuits are configured to adapt to the electrical characteristic differences between different devices.

[0076] The unit control system can be used to monitor and adjust the operating state of the wind turbine generator set, including functions such as controlling the wind turbine speed, power output, and equipment protection. It can store and manage a large amount of data related to the operation of the wind turbine generator set, including basic parameter information.

[0077] A standard communication protocol can be a widely recognized and followed communication rule for data transmission and interaction between different devices or systems. Common standard communication protocols such as Modbus, OPC UA, etc. Using a standard communication protocol in this solution ensures accurate data exchange between the information acquisition unit and the unit control system. For example, the Modbus TCP protocol is adopted for data transmission based on Ethernet, which has advantages such as good openness and fast transmission speed, and can efficiently read data in the unit control system.

[0078] In this technical solution, a physical connection can be established between the basic parameter information acquisition unit 211 and the unit control system through the preset interface, enabling the two to perform data interaction. This process may involve hardware connection and software - level initialization configuration. On the basis of establishing the connection, according to the rules of the standard communication protocol, the configuration and initialization of the communication link are completed to ensure stable data transmission between the two. For example, by setting parameters such as the IP addresses and port numbers of both communication parties, and negotiating parameters such as communication rate and verification method, a stable Modbus TCP communication link is established. Furthermore, the basic parameter information of the wind turbine generator set, such as power rating, tower height, and communication requirement information, can be extracted from the data stored in the unit control system.

[0079] The installation location can refer to the geographical location where the wind turbine generator set is actually installed and operated. This location information is crucial for obtaining accurate environmental parameters because the environmental conditions vary greatly in different geographical locations.

[0080] Historical environmental parameters can refer to the environmental data records of the installation location of the wind turbine generator set over a past period of time, and these data reflect the long - term characteristics and change rules of the environmental conditions at this location.

[0081] Wind force level can be an indicator for measuring the magnitude of wind force, and is usually divided into different levels according to the degree of influence of the wind force on objects. Wind force level is of great significance for evaluating the wind energy utilization efficiency of wind turbines and the wind loads on cables. Wind force distribution months can record the distribution of wind force magnitudes in different months of a year, which helps to understand the seasonal variations of wind energy resources in this area and provides a basis for the wind-resistant design of cables. Wind force extremes refer to the maximum and minimum wind force values that occur in this area within a certain time period, and are crucial for evaluating the safety of cables under extreme wind conditions.

[0082] Accumulated sunshine duration can refer to the total duration of sunlight irradiation in this area in a year, which affects the aging rate and thermal performance of cable materials. Sunshine extremes can be the maximum and minimum sunshine durations in a year, reflecting the extreme conditions of sunshine time in this area, and having reference value for the thermal management design of cables.

[0083] Rainfall distribution months can record the distribution of rainfall in different months of a year, helping to understand the seasonal patterns of rainfall in this area, so as to consider factors such as waterproofing and drainage in cable design. Rainfall extremes per unit time can be the maximum rainfall that occurs within a certain time period, such as per hour or per day, and play an important role in evaluating the electrical performance and waterproof performance of cables under heavy rainfall conditions.

[0084] This solution can determine the installation location of the wind turbine through positioning technology. According to the obtained location information, historical environmental parameter data at this location is searched for and extracted from relevant environmental data storage systems, such as meteorological databases, local data storage servers, etc.

[0085] This technical solution accurately obtains basic parameter information from the unit control system and comprehensively obtains historical environmental parameter information from the environmental data storage system. The acquisition of this information provides a data basis for the subsequent evaluation of the integration feasibility of the power transmission, signal control, and fiber optic communication functions of the wind turbine and the design of the integrated cable, helping to design a wind power cable integrated system that better meets the actual needs and has better performance, improving the stability of the entire wind power system, and reducing operation and maintenance costs and potential risks.

[0086] Embodiment 3

[0087] Based on the above embodiments, this embodiment is further optimized. Specifically, the optimization is as follows: The feasibility evaluation module includes: An information processing unit for splitting the influencing factors of the basic parameter information and the environmental parameter information to obtain a thermal stability evaluation factor, a shielding requirement evaluation factor, and a mechanical strength evaluation factor; A feasibility calculation unit for determining whether there are incompatible items in the basic parameters that meet the power transmission function, signal control function, and optical fiber communication function of the wind turbine according to the thermal stability evaluation factor, the shielding requirement evaluation factor, and the mechanical strength evaluation factor. If there are no incompatible items, it is determined that there is integration feasibility. If there are incompatible items, it is determined that there is no integration feasibility. Figure 3 It is a schematic structural diagram of an integrated R & D and design device for a wind power cable provided in Embodiment 3 of the present application. As Figure 3 shown, the device includes:

[0088] An information acquisition module 310 for acquiring the basic parameter information and environmental parameter information of the wind turbine; wherein, the basic parameter information includes at least one of the power level, tower height, and communication requirement information; the environmental parameter information includes at least one of the operating environment wind parameters, sunshine parameters, and rainfall parameters of the wind turbine;

[0089] A feasibility evaluation module 320 for determining whether there is integration feasibility in the power transmission function, signal control function, and optical fiber communication function of the wind turbine according to the basic parameter information and the environmental parameter information;

[0090] An integrated design module 330 for, when there is integration feasibility, inputting the basic parameter information and the environmental parameter information into a cable integrated design model, and determining the design data of the integrated cable according to the output result of the cable integrated design model; wherein, the design data includes the segmented length, insulation layer thickness, shielding layer material, and cable core winding method.

[0091] Among them, the feasibility evaluation module 320 includes:

[0092] An information processing unit 321 for splitting the influencing factors of the basic parameter information and the environmental parameter information to obtain a thermal stability evaluation factor, a shielding requirement evaluation factor, and a mechanical strength evaluation factor;

[0093] A feasibility calculation unit 322 for determining whether there are incompatible items in the basic parameters that meet the power transmission function, signal control function, and optical fiber communication function of the wind turbine according to the thermal stability evaluation factor, the shielding requirement evaluation factor, and the mechanical strength evaluation factor. If there are no incompatible items, it is determined that there is integration feasibility. If there are incompatible items, it is determined that there is no integration feasibility.

[0094] Among them, the splitting of influencing factors can be to decompose complex basic parameter information and environmental parameter information into more targeted evaluation factors according to their impacts on key performance indicators in different function implementation processes, such as power transmission, signal control, and optical fiber communication. This splitting helps to analyze the effects of each parameter on the system function more meticulously, providing a clear and effective data basis for subsequent feasibility calculations.

[0095] The thermal stability evaluation factor can be a parameter factor used to evaluate the ability of relevant equipment in a wind turbine generator to maintain a stable thermal state during operation. For example, it may include a comprehensive consideration of factors such as power rating, ambient temperature, cable conductor resistance, and thermal conductivity of insulating materials. These factors interact with each other to jointly affect the heat generation and dissipation of the cable during power transmission, thereby affecting its thermal stability. Specifically, the power rating determines the amount of heat generated by the cable, the ambient temperature affects the heat dissipation efficiency, and the cable conductor resistance and thermal conductivity of insulating materials respectively affect the rate of heat generation and conduction.

[0096] The shielding requirement evaluation factor can be a parameter factor for the signal control function and optical fiber communication function to measure the degree of demand for shielding measures to ensure that signals are not interfered in a specific environment. This may involve the intensity and frequency of electromagnetic interference sources in the operating environment, as well as the characteristics of communication signals. For example, in a high electromagnetic interference environment, if the communication signal frequency is low and vulnerable to interference, stronger shielding measures are required, and the shielding requirement evaluation factor will reflect this high demand at this time.

[0097] The mechanical strength evaluation factor can be a parameter factor used to evaluate the ability of each component of a wind turbine generator, such as the wind power cable itself, to maintain structural integrity and normal function under various mechanical external forces. It covers factors such as tower height, wind parameters in the operating environment, and the self-weight of the cable. The tower height affects the suspension length of the cable and the gravitational force acting on it, and the wind speed and wind pressure determine the magnitude of the wind load borne by the cable. These factors jointly determine the mechanical strength required by the cable.

[0098] This technical solution can perform operations on splitting the influencing factors of basic parameter information and environmental parameter information. Through the analysis and processing of the split information, the thermal stability evaluation factor, shielding requirement evaluation factor, and mechanical strength evaluation factor are refined. For example, by establishing a heat conduction model and combining parameters such as power rating and ambient temperature, the thermal stability evaluation factor is calculated; based on electromagnetic theory, the shielding requirement evaluation factor is obtained by analyzing the electromagnetic interference source and communication signal characteristics; using mechanical principles, the mechanical strength evaluation factor is calculated by comprehensively considering tower height, wind parameters, and cable self-weight.

[0099] Incompatible items refer to the situation where, when meeting the functional requirements of a wind turbine generator set, there are contradictions or the requirements cannot be satisfied simultaneously among the requirements of different functions for basic parameters. For example, to meet the thermal stability requirements of the power transmission function, a certain specific cable insulation material and thickness may be required, but this choice may have a negative impact on the shielding performance required by the signal control function, resulting in an increase in signal interference. This is an incompatible item.

[0100] This solution can, through a series of logical judgment and calculation processes, draw a conclusion on whether there are incompatible items, and based on this, judge whether there is integration feasibility. This may involve establishing an evaluation model and substituting evaluation factors into the model for calculation and comparison. For example, setting reasonable value ranges for each evaluation factor for different functions, if the value range of the thermal stability evaluation factor required by a certain function cannot be coordinated with the value range of the shielding requirement evaluation factor required by another function in terms of cable design parameters, it is determined that there are incompatible items. In this process, there is actually an implicit judgment operation on the compatibility between the basic parameters of each function. By comparing the requirements of different functions for evaluation factors, it is judged whether the requirements of each function can be satisfied simultaneously under a set of basic parameter settings.

[0101] The technical solution provided by this embodiment can comprehensively and deeply analyze the problems that may be faced by different functions of a wind turbine generator set during integration, providing decision-making support for subsequent integration design. Only the integration design carried out after determining the integration feasibility can more effectively meet the functional requirements of the wind turbine generator set in multiple aspects such as power transmission, signal control, and optical fiber communication, improve the overall performance of the system, and reduce design risks and costs.

[0102] In one embodiment, optionally, the information processing unit is specifically configured to:

[0103] Calculate the minimum current-carrying capacity of the cable according to the power rating and cable length of the wind turbine generator set, and calculate the thermal stability evaluation factor of the cable operating at the minimum current-carrying capacity under different ambient temperatures;

[0104] Calculate the shielding requirement evaluation factor of the cable according to the electromagnetic interference intensity, signal transmission distance, and signal accuracy requirements of the wind turbine generator set;

[0105] Determine the mechanical strength evaluation factor of the cable according to the environmental corrosiveness factor and mechanical stress of the wind turbine generator set.

[0106] Among them, the power rating can be an indicator representing the power generation capacity of the wind turbine generator set, reflecting the electric power that the unit can output under specific operating conditions, usually with the unit of kilowatt (kW) or megawatt (MW). It directly affects the heat generated when the cable transmits electric energy. The greater the power, the more heat generated by the cable during transmission.

[0107] The cable length can refer to the actual length of the cable between the wind turbine generator and the power access point or related equipment. The cable length affects the resistance, which in turn affects the power loss and heat generation during power transmission.

[0108] The minimum current-carrying capacity can be the minimum current value that the cable can safely carry under the power transmission requirements for the normal operation of the wind turbine generator. It is a key parameter to ensure the normal operation of the cable and is related to the power rating and electrical characteristics of the cable.

[0109] The thermal stability evaluation factor can be a quantitative index used to measure the ability of the cable to maintain a stable thermal state when operating at the minimum current-carrying capacity under different ambient temperatures. It comprehensively considers factors such as the power rating, cable length, ambient temperature, and the cable's own thermal characteristics, reflecting the balance between heat generation and heat dissipation during cable operation.

[0110] This solution can perform mathematical operations using specific electrical and thermal formulas and principles. According to the power formula, the minimum current-carrying capacity can be calculated when the power rating and the rated voltage of the cable are known. For the calculation of the thermal stability evaluation factor, the cable resistance formula and the heat conduction formula can be combined, and considering the heat dissipation under different ambient temperatures, such as the relevant formulas for convection and radiation heat dissipation, the thermal stability evaluation factor can be comprehensively calculated.

[0111] This solution can accurately calculate the thermal stability evaluation factor, which helps to accurately evaluate the thermal stability performance of the cable when operating at the minimum current-carrying capacity under different ambient temperatures, provides a key basis for subsequent judgment of the feasibility of the power transmission function under different conditions, ensures that the cable will not be damaged due to overheating during power transmission, and guarantees the stability of power transmission of the wind turbine generator.

[0112] Calculate the shielding requirement evaluation factor according to factors such as electromagnetic interference. Among them, the electromagnetic interference intensity can be a physical quantity describing the influence degree of the electromagnetic interference source existing in the operating environment of the wind turbine generator on the electromagnetic environment of the surrounding space, and the unit is usually volts per meter (V / m) or amperes per meter (A / m). The greater the interference intensity, the more serious the interference to the signal transmission inside the cable.

[0113] The signal transmission distance can refer to the distance between the signal source and the signal receiver, such as the distance between the sensor or control module inside the wind turbine generator and the main control system or remote monitoring equipment. The signal attenuates as the distance increases during transmission. The longer the transmission distance, the more serious the signal attenuation, and the higher the requirements for shielding and signal enhancement measures.

[0114] The signal accuracy requirement can represent the accuracy requirement for the accurate transmission of various signals, such as control signals and monitoring data signals, during the operation of a wind turbine generator. For example, some key control signals may require an error not exceeding a certain percentage, which determines the anti-interference ability that the cable needs to possess to ensure the accuracy of the signal during transmission.

[0115] The shielding requirement assessment factor can be a quantitative index used to measure the degree of shielding required for the cable to ensure accurate signal transmission under given electromagnetic interference intensity, signal transmission distance, and signal accuracy requirements. It comprehensively reflects the ability requirement of the cable to resist electromagnetic interference and maintain signal accuracy.

[0116] In this solution, mathematical analysis and operations can be carried out based on electromagnetics and signal transmission theory. For example, according to the electromagnetic interference propagation model, combined with the electromagnetic interference intensity and signal transmission distance, calculate the attenuation degree of the signal during transmission and the magnitude of the interference received. Then, based on the signal accuracy requirement, through the signal integrity analysis method, determine the shielding effectiveness required to ensure signal accuracy, and further obtain the shielding requirement assessment factor. For example, the Friis transmission formula can be used to calculate the attenuation of the signal propagating in free space, and the shielding effect of different shielding materials and structures on electromagnetic interference can be calculated according to the electromagnetic shielding theory, etc.

[0117] Determine the mechanical strength assessment factor according to the environmental corrosivity and mechanical stress. Among them, the environmental corrosivity factor can refer to various factors in the environment where the wind turbine generator is located that may cause corrosion to the cable material, such as humidity, pH value, salt mist concentration, and chemical gas components, etc. These factors will gradually erode the outer sheath, insulation layer, and even the conductor of the cable, reducing the mechanical and electrical properties of the cable.

[0118] Mechanical stress can be various external forces exerted on the cable during operation, including its own gravity, tensile force and vibration caused by wind, tensile force during installation, and thermal stress caused by temperature changes, etc. Excessive mechanical stress will cause the cable structure to deform and break, affecting its normal use.

[0119] The mechanical strength assessment factor can be a quantitative index that comprehensively reflects the ability of the cable to resist environmental corrosion and mechanical stress. It takes into account the weakening of the cable material performance by environmental corrosivity factors and the impact of mechanical stress on the cable structure integrity, and is used to evaluate the mechanical stability of the cable in the actual operating environment.

[0120] This solution can comprehensively analyze the influence of environmental corrosivity factors and mechanical stress on the mechanical properties of cables based on relevant knowledge such as materials science, mechanics, and corrosion science, through methods such as experimental data, theoretical models, and empirical formulas, to obtain the mechanical strength evaluation factor. For example, by simulating the corrosion experiments of cable materials under different environmental corrosivity conditions, the change data of material properties over time can be obtained; combined with mechanical analysis, the stress distribution and deformation of the cable under various mechanical stresses can be calculated. Then, a mathematical model is used to integrate these data to determine the mechanical strength evaluation factor.

[0121] This technical solution comprehensively and meticulously analyzes the relationship between the requirements and actual operating conditions of a wind turbine generator in aspects such as power transmission, signal control, and mechanical properties by accurately calculating or determining the corresponding evaluation factors for different aspects. These evaluation factors provide specific and quantitative judgment bases for the feasibility calculation unit, making the evaluation of the feasibility of each function integration of the wind turbine generator more scientific and accurate. Based on this evaluation result, potential problems and incompatibilities can be discovered in advance, providing strong support for the subsequent integrated design, thereby optimizing the design scheme, improving the stability of the wind power generation system, and reducing costs and risks.

[0122] In one embodiment, optionally, the feasibility calculation unit is specifically configured to:

[0123] When it is determined that the power transmission function of the wind turbine generator needs to be satisfied, determine whether there are evaluation factors that cannot meet the set standards with each other among the thermal stability evaluation factor, shielding requirement evaluation factor, and mechanical strength evaluation factor. If so, determine that there are incompatible items.

[0124] Among them, the power transmission function can be to efficiently and stably transmit the electric energy generated by wind power conversion to the power grid or other electrical equipment. Its realization depends on transmission equipment such as cables, and the performance of these equipment is affected by various factors, and the thermal stability evaluation factor, shielding requirement evaluation factor, and mechanical strength evaluation factor are all within the scope of consideration.

[0125] The thermal stability evaluation factor can be used to measure the ability of the cable to maintain a stable thermal state when operating at the minimum current-carrying capacity under different environmental temperatures during the power transmission process. It comprehensively considers factors such as power level, cable length, environmental temperature, and the cable's own thermal characteristics, reflecting the balance relationship between heat generation and heat dissipation of the cable when transmitting electric energy. If the thermal stability is not good, it may cause the cable to be damaged due to overheating, affecting the stability of power transmission.

[0126] The shielding requirement assessment factor can be aimed at the electromagnetic interference problem that may exist during the power transmission process. This factor considers the electromagnetic interference intensity, signal transmission distance and signal accuracy requirements in the operating environment of the wind turbine to evaluate the degree of shielding required for the cable to ensure accurate signal transmission. Sufficient shielding capability is essential to ensure the accuracy of control signals and monitoring data during power transmission.

[0127] The mechanical strength assessment factor can be the ability of the cable to maintain structural integrity and normal function when it withstands various mechanical external forces during the operation of the wind turbine and resists environmental corrosion. Insufficient mechanical strength may cause structural damage to the cable during operation, thereby affecting power transmission.

[0128] The setting standard can be a pre-established performance indicator or value range for each evaluation factor, which is determined based on the normal operation requirements of the power transmission function of the wind turbine generator set and relevant industry specifications and technical standards. For example, for the thermal stability evaluation factor, the setting standard may be the maximum allowable temperature of the cable under a specific ambient temperature and current carrying capacity; for the shielding demand evaluation factor, the setting standard may be the maximum allowable signal attenuation rate under a given electromagnetic interference intensity and signal transmission distance; for the mechanical strength evaluation factor, the setting standard may be the minimum tensile strength that the cable should have under various mechanical stresses and environmental corrosion conditions, etc.

[0129] This solution can use specific judgment logic and calculation methods to analyze and judge the given conditions and draw clear conclusions. Specifically, by comparing and analyzing the thermal stability assessment factor, shielding demand assessment factor, and mechanical strength assessment factor with their respective set standards, it can be determined whether there is a situation where the set standards cannot be met. Make all conditions meet the requirements for the normal operation of the power transmission function of the wind turbine. By comparing and comprehensively analyzing the three assessment factors with the set standards one by one, it can be determined whether there is a situation where at least one assessment factor cannot meet the set standard due to the limitations of other assessment factors.

[0130] By precisely comparing the relationships between the thermal stability evaluation factor, the shielding requirement evaluation factor, and the mechanical strength evaluation factor with the set standards, this solution can keenly capture potential conflicts and incompatibilities among these factors. This meticulous analysis method provides a solid basis for judging the feasibility of integrating the power transmission function of a wind turbine generator set. Once incompatibilities are detected, designers can be aware in advance of the problems that may arise in achieving the integration of the power transmission function under current conditions, and then adjust the design plan accordingly, such as optimizing cable materials, structures, or improving installation methods, etc., to avoid system failures or poor performance caused by conflicting performance indicators during actual implementation. In this way, the effectiveness of the wind power system design can be improved, the development cost and risks can be reduced, and it is ensured that the finally designed system can operate stably and efficiently.

[0131] In one embodiment, optionally, the feasibility calculation unit is specifically configured to:

[0132] When it is determined that the signal control function of the wind turbine generator set needs to be satisfied, determine whether there are evaluation factors among the thermal stability evaluation factor, the shielding requirement evaluation factor, and the mechanical strength evaluation factor that cannot meet the set standards for each other. If so, determine that there are incompatibility items.

[0133] Among them, the signal control function is the function in the wind turbine generator set responsible for realizing accurate signal transmission and effective control among various components. It ensures that operation instructions such as the start, stop, and speed regulation of the unit can be accurately conveyed, and at the same time ensures that various sensor data are accurately fed back to the control system. It is a key link to maintain the stable and efficient operation of the wind turbine generator set.

[0134] The thermal stability evaluation factor refers to the ability of equipment to maintain a stable thermal state under the influence of factors such as power loss and environmental temperature during the operation of signal control-related equipment. For example, electronic components in the signal control module generate heat during operation, and the thermal stability evaluation factor is an index that measures whether these components can maintain an appropriate temperature under different working conditions to ensure that signal processing and transmission are not interfered by heat.

[0135] The shielding requirement evaluation factor can be that, given the extremely high requirement of the signal control function for signal transmission accuracy, this factor is used to evaluate the shielding ability required for signal transmission lines in response to various electromagnetic interferences existing in the operating environment of the wind turbine generator set. Electromagnetic interference may come from equipment such as generators and converters. The shielding requirement evaluation factor comprehensively considers factors such as interference intensity, signal frequency, and transmission distance to determine the shielding degree required to ensure signal quality.

[0136] The mechanical strength evaluation factor. During the implementation of the signal control function, the devices and circuits involved need to withstand certain mechanical external forces, such as vibration, tension, and bending. The mechanical strength evaluation factor is an ability index that measures the ability of these devices and circuits to maintain structural integrity and normal working performance under the action of such mechanical stresses for a long time.

[0137] The set standards can be specific performance indicators or value ranges respectively set for the thermal stability evaluation factor, shielding requirement evaluation factor, and mechanical strength evaluation factor according to relevant industry standards, technical specifications, and actual operation requirements for the signal control function. For example, for the thermal stability evaluation factor, the set standard may be that the temperature rise of key components of the signal control device does not exceed a certain threshold after continuous operation for a certain period of time; for the shielding requirement evaluation factor, the set standard may be that the bit error rate of signal transmission is lower than a certain value in a specific electromagnetic interference environment; for the mechanical strength evaluation factor, the set standard may be that the electrical performance change of the signal transmission line does not exceed the allowable range after experiencing a certain number of vibrations or bends.

[0138] This solution can use special algorithms and judgment logics to comprehensively analyze the given conditions and evaluation factors, thereby obtaining a clear judgment result. In this case, it is to judge the relationship between each evaluation factor and the set standards on the premise of meeting the signal control function. Make each condition and evaluation factor meet the requirements necessary for the normal operation of the signal control function of the wind turbine generator set. That is, the thermal stability evaluation factor, shielding requirement evaluation factor, and mechanical strength evaluation factor should all be within their respective set standard ranges to ensure the stability of the signal control function. By comparing and comprehensively considering the thermal stability evaluation factor, shielding requirement evaluation factor, and mechanical strength evaluation factor with the set standards in detail, judge whether there is a situation where at least one evaluation factor fails to meet the set standards due to the influence of other factors.

[0139] In this technical solution, the feasibility calculation unit can accurately identify potential incompatibility problems by strictly determining the degree of fit between each evaluation factor and the set standards when meeting the signal control function of the wind turbine generator set. This in-depth analysis provides a scientific basis for the judgment of the feasibility of signal control function integration. Once incompatibility items are found, technicians can optimize and adjust the design in advance, such as improving the heat dissipation structure of the signal control device, optimizing the shielding material and method, and enhancing the mechanical protection of the circuit, to avoid signal control failures caused by the mismatch of these factors during the actual system construction and operation process. In this way, the stability of the signal control part in the wind power generation system is effectively improved, the overall performance of the wind turbine generator set is guaranteed, and the later maintenance cost and potential risks are reduced.

[0140] In one embodiment, optionally, the feasibility calculation unit is specifically used for:

[0141] When it is determined that the optical fiber communication function of the wind turbine needs to be satisfied, it is necessary to determine whether there are evaluation factors that cannot meet the set standards with each other among the thermal stability evaluation factor, the shielding requirement evaluation factor, and the mechanical strength evaluation factor. If so, it is determined that there are incompatible items.

[0142] Among them, the optical fiber communication function is an important function for high-speed and stable data and signal transmission in wind turbines. Using optical fiber as the transmission medium, it can achieve large-capacity, low-loss, and anti-interference data transmission, meeting the communication requirements between various components inside the wind turbine and between the wind turbine and external monitoring and control systems, such as transmitting real-time operation data, control instructions, etc.

[0143] The shielding requirement evaluation factor mainly considers the degree and effect of the shielding measures required to ensure that the optical fiber communication signal is not affected by electromagnetic interference in the complex electromagnetic environment of the wind turbine. There are various electrical equipment and electromagnetic interference sources in the wind turbine, such as generators, frequency converters, etc. The electromagnetic radiation they generate may interfere with the optical fiber communication signal. The shielding requirement evaluation factor comprehensively considers factors such as the intensity and frequency of the interference source and the anti-interference requirements of the optical fiber communication system.

[0144] The set standards are a series of quantitative indicators or performance ranges determined in advance for the thermal stability evaluation factor, the shielding requirement evaluation factor, and the mechanical strength evaluation factor according to the normal operation requirements of the optical fiber communication function, relevant industry standards and specifications. For example, the set standard for the thermal stability evaluation factor may stipulate the maximum allowable operating temperature of the optical fiber communication equipment within a specific environmental temperature range; the set standard for the shielding requirement evaluation factor may stipulate the maximum allowable attenuation of the optical fiber communication signal under a specific electromagnetic interference intensity; the set standard for the mechanical strength evaluation factor may stipulate the minimum fracture strength of the optical fiber when it withstands a certain tensile force or bending radius, etc.

[0145] This solution can obtain a clear conclusion on whether there are incompatible situations by conducting a detailed comparative analysis and logical judgment on the thermal stability evaluation factor, the shielding requirement evaluation factor, and the mechanical strength evaluation factor and their respective set standards. In this process, the actual values or performance manifestations of the thermal stability evaluation factor, the shielding requirement evaluation factor, and the mechanical strength evaluation factor meet the standards set for the optical fiber communication function. Only when all evaluation factors meet the set standards can it be considered that the optical fiber communication function has integration feasibility under the current conditions. During the comparative analysis of the three evaluation factors and the set standards, it is found that at least one evaluation factor cannot meet its corresponding set standard due to the influence of other factors or the contradictory relationship between them.

[0146] Through strict review and judgment of each evaluation factor and the set standards when meeting the optical fiber communication function, potential problems and risks that may exist in the integration process of the optical fiber communication function can be discovered in advance. Once incompatibilities are identified, designers can adjust the design plan in a timely manner, such as optimizing the heat dissipation structure of the equipment, improving the shielding material and method, and adjusting the mechanical protection measures of the optical fiber, so as to avoid optical fiber communication failures or performance degradation caused by mismatches in each performance index during the actual implementation process. This helps to improve the stability and performance of the optical fiber communication system of the wind turbine generator, reduce the construction cost and maintenance cost of the system, and ensure the efficient and stable operation of the wind turbine generator.
