Description

Technical Field

[0001] This application relates to the field of wind turbine generator technology, and in particular to a wind turbine operating condition testing platform, method, electronic equipment and storage medium. Background Technology

[0002] Currently, the overall design of wind turbine units is typically based on simulation design according to standards such as IEC-61400-1. This involves determining the ultimate load and fatigue load of each component through design load conditions, thereby guiding component selection and control strategy development. However, in actual engineering, there are significant deviations between the bench tests of wind turbine components and the on-site operating conditions of the unit and the design phase in terms of model accuracy, load timing, and control logic. Traditional bench tests often employ equivalent load loading or fatigue / durability tests under single operating conditions, which fail to accurately reflect the dynamic response under the coupling of the rotor-drivetrain-tower. On the other hand, on-site operation testing faces drawbacks such as long cycles, high risks, and difficulties in reproducing problems.

[0003] Therefore, there is a need for a testing platform that can fully and consistently reproduce the actual operating conditions of various types of wind farms using test conditions, in order to shorten the testing cycle, move the risk identification node forward, and reduce the cost of on-site trial and error.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to facilitate the reader's better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0023] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] In related technologies, significant discrepancies exist between bench tests of wind turbine components and actual on-site operating conditions compared to the design phase in terms of model accuracy, load timing, and control logic. Traditional bench tests often employ equivalent load loading or fatigue / durability tests under single operating conditions, failing to accurately reflect the dynamic response under the coupled rotor-drivetrain-tower configuration. On-site operational testing, however, suffers from drawbacks such as long cycles, high risks, and difficulties in reproducing problems. Therefore, a method is needed that can comprehensively and consistently reproduce the actual operating conditions of various wind farms using test conditions on a testing platform, thereby shortening the testing cycle, advancing risk identification, and reducing on-site trial-and-error costs.

[0025] In this embodiment, the wind turbine operating condition testing platform includes: a scheduling module, a simulation module, a bench control module, and a wind turbine control module. A virtual prototype is deployed on the bench control module. The scheduling module is used to generate a wind turbine simulation model based on preset operating condition information, and to generate operating condition test information based on the type of operating condition to be tested and the operating condition information. The scheduling module is also used to schedule the simulation module, the bench control module, and the wind turbine control module in real time to perform operating condition tests. The simulation module is used to generate wind turbine operation information and load information based on the wind turbine simulation model, the operating condition test information, and preset wind condition information. The scheduling module is also used to generate loading torque information based on the load information and the preset loading type. The bench control module is used to apply load and torque to the virtual prototype based on the load information and the loading torque information. The wind turbine control module is used to control the virtual prototype based on the wind turbine operation information so that the virtual prototype outputs operating condition test information. The wind turbine operating condition testing platform of this application uses a scheduling module to schedule the simulation module, bench control module and wind condition control module in real time, so as to realize real-time operating condition testing of wind turbines from operating condition definition, simulation calculation, load torque calculation and application to operation testing; thereby, it can reproduce the actual operating conditions of various types of wind farms, so as to shorten the testing cycle, move the risk identification node forward and reduce the cost of on-site trial and error.

[0026] The following details the implementation of the wind turbine operating condition testing platform and wind turbine operating condition testing method according to the embodiments of this application. The following content is only for the convenience of understanding and is not necessary for implementing this solution.

[0027] One embodiment of this application relates to a wind turbine operating condition testing platform, such as... Figure 1As shown, the wind turbine operating condition test platform includes a scheduling module 110, a simulation module 120, a bench control module 130, and a wind turbine control module 140. The wind turbine operating condition test platform is a hardware-in-the-loop test bench, and the implementation details of each module's function are as follows.

[0028] The scheduling module 110 is used to generate a wind turbine simulation model based on preset operating condition information, and to generate operating condition test information based on the type of operating condition to be tested and the operating condition information.

[0029] Specifically, such as Figure 2 As shown, the scheduling module 110 includes a working condition definition unit 210, a simulation model unit 211, a data conversion and transmission unit 212, a working condition test unit 213, a loading torque calculation unit 214, and a system scheduling and monitoring unit 215.

[0030] Specifically, the operating condition definition unit 210 has a pre-set operating condition table. This table defines the operating condition information required by other modules of the wind turbine operating condition test platform during testing, serving as the data foundation for the platform to reproduce the actual operating conditions of various types of wind farms. As shown in Table 1, the operating condition information included in the table includes at least one of the following: operating condition status word, wind speed, turbulence, shear, wind direction, simulation duration, sampling settings, yaw information, wind file, fault status word, and fault time setting; among which, yaw information includes yaw fault time, yaw fault type, and yaw rate. The operating condition table can be stored as a text file or a database table. This application allows users to define various operating conditions, such as IEC standard design load conditions, custom limit conditions, or characteristic conditions based on field measurements and statistics, through flexible configuration of the operating condition information in the operating condition table. This ensures the consistency between the loading conditions of the wind turbine operating condition test platform and the design expectations or field benchmarking targets.

[0031] Table 1: Operating condition information defined in the operating condition table

[0032] Specifically, after the operating condition information in the operating condition definition unit 210 is confirmed, the simulation model unit 211 automatically generates the corresponding wind turbine simulation model based on the operating condition information. The generated wind turbine simulation model can be opened and run using simulation software Envision-Simulation Software or other commercial software such as Bladed and FAST. The wind turbine simulation model includes at least a rotor aerodynamic model, a blade and tower structural dynamics model (including aeroelastic characteristics and tower vibration), a transmission chain model, and a pitch and generator control interface model. The wind turbine simulation model generated by the simulation model unit 211 is generated for a single operating condition, and the generated wind turbine simulation model changes with the operating condition information in the operating condition definition unit. In other words, the simulation settings parameters used in the wind turbine simulation model generated by the simulation model unit 211 are different when conducting different operating condition tests; it is not a case of using the same wind turbine simulation model to test different wind turbine operating conditions.

[0033] Specifically, the operating condition test information mentioned in this application is generated in real time based on the operating condition information and the type of operating condition to be tested. The generated operating condition test information will change according to the changes in the operating condition information input by the user and the type of operating condition to be tested. The operating condition test unit 213 first determines the type of operating condition to be tested specified by the user. The type of operating condition to be tested includes at least one of the following: pitch electrical fault condition, pitch gearbox fault condition, pitch bearing fault condition, external wind load abnormality fault condition, full IEC design condition, and custom condition; among which, the full IEC design condition includes normal power generation condition, power generation and fault condition, start-up and shutdown condition, standby condition, shutdown plus extreme wind condition, and transportation / installation / maintenance condition; in addition, it also supports extreme wind condition, special fault combination condition, or wind farm benchmark condition constructed by the user based on field measured data or custom requirements. After the type of operating condition to be tested is determined, the operating condition test unit 213 will obtain the corresponding information from the operating condition information according to the type of operating condition to be tested, and then generate complete operating condition test information for the entire operating condition test process. If the specified type of operating condition to be tested includes multiple types of operating conditions, the generated operating condition test information also includes the test order of each type of operating condition. This application can automatically generate complete operating condition test information based on the type of operating condition to be tested and the operating condition information, without the need to manually set the simulation model and test sequence item by item, which can improve the efficiency and repeatability of the pre-test preparation.

[0034] Specifically, the data transmission between the scheduling module 110 and the simulation module 120, the test bench control module 130 and the wind turbine control module 140 is completed through the data conversion and transmission unit 212 in the scheduling module 110. The data conversion and transmission unit 212 can convert the data output by the scheduling module 110 to other modules and the data received by the scheduling module from other modules in real time according to the signal or data format that each module can recognize and use, thereby realizing lossless and low-latency real-time transmission.

[0035] The scheduling module 110 is also used for real-time scheduling of the simulation module, bench control module and wind turbine control module for operating condition testing.

[0036] Specifically, such as Figure 3 The timing diagram for the working condition test shown indicates that after the working condition definition unit 210 and simulation model unit 210 of the scheduling module complete their corresponding tasks, before formally entering the working condition test, the system scheduling and monitoring unit 215 in the scheduling module 110 will monitor the operating status of the simulation module 120, the bench control module 130, and the wind turbine control module 140 in real time. The operating status of each module includes standby, running, paused, terminated, fault, etc. Only when the operating status of each module is standby can the system scheduling and monitoring unit 215 call the corresponding module to perform the working condition test.

[0037] Specifically, the system scheduling and monitoring unit 215 will sequentially call the simulation module 120, the bench control module 130, and the wind turbine control module 140 to test each operating condition according to the test order and test strategy in the operating condition test information. The test strategy is determined based on the safety level. At a high safety level, the test strategy is to pause the test and issue an alarm if an anomaly occurs in operating condition 1 during the test; at a low safety level, the test strategy is to skip the test of operating condition 1 and proceed to the test of operating condition 2 according to the test order if an anomaly occurs in operating condition 1 during the test.

[0038] Specifically, the operation of the data conversion and transmission unit 212, the working condition test unit 213, and the loading torque calculation unit 214 in the scheduling module are also subject to the scheduling of the system scheduling and monitoring unit 215.

[0039] The simulation module 120 is used to generate wind turbine operation information and load information based on the wind turbine simulation model, operating condition test information and preset wind condition information.

[0040] Specifically, when the system scheduling and monitoring unit 215 determines that the simulation module's operating status is standby, the system scheduling and monitoring unit 215 sends the wind turbine simulation model, operating condition test information, and preset wind condition information to the simulation module 120 through the data conversion and transmission unit 212. The simulation module 120 then runs the wind turbine simulation model and applies the operating condition test information and wind condition information to the running wind turbine simulation model. The wind turbine simulation model performs real-time calculations to obtain the wind turbine operating information subsequently output to the wind turbine control module 140, and the load information output to the test bench control module 130. This application enables the rapid deployment of different design operating conditions or wind farm benchmark operating conditions on the wind turbine operating condition test platform through the wind turbine simulation model, without the need for manual construction or adjustment of the simulation model, thereby significantly shortening the operating condition test cycle and improving the efficiency and consistency of operating condition reproduction.

[0041] Specifically, the load information output to the test bench control module 130 includes at least one of the following: force at the blade root in a specified direction, torque at the blade root in a specified direction, and pitch loading side torque; wherein, the force at the blade root in the specified direction includes the force F at the blade root in the X direction. X The force F at the leaf root in the Y direction Y The force F of the leaf root in the Z direction Z The torque at the blade root in the specified direction includes the torque M at the blade root in the X direction. X Torque M at the blade root in the Y direction Y The pitch loading-side torque is the pitch loading-side torque M in the Z direction. Z The wind turbine operating information output to the wind turbine control module 140 includes information such as nacelle position, blade angle, speed, acceleration, and wind conditions used to control wind turbine operation.

[0042] The scheduling module 110 is also used to generate loading torque information based on load information and preset loading type.

[0043] Specifically, such as Figure 3 The working condition test timing diagram shown shows that after the simulation model module generates wind turbine operation information and load information, it will return them to the scheduling module 110 through the data conversion and transmission unit 212. The loading torque calculation unit 214 of the scheduling module 110 will calculate the loading torque information of different platforms according to the load information and the corresponding loading type.

[0044] Specifically, the loading torque calculation unit 214 first obtains the propeller angle loading side torque from the load information. Then, determine the friction torque corresponding to the loading type based on the loading type. Then, you can apply the loading torque formula... Generate the corresponding loading torque; where, To load torque information, For pitch loading side torque, Let I be the frictional torque, I be the moment of inertia, and acc be the acceleration. The loading torque calculation unit of this application uses a loading calculation method that can compensate for the influence of the test bench's own inertia and signal delay on the accuracy of the loading torque by adding virtual inertia, ensuring that the actual load output by the test bench control module and the simulated target load are consistent with high precision.

[0045] Specifically, the loading torque calculation unit 214 can be used to calculate, for example, the loading torque calculation unit 214. Figure 4 The motor's loading torque information on the towing platform shown and / or as follows Figure 5 The loading torque information of the blade hub platform is shown; both the motor-driven platform and the blade hub platform include a loading side and a driving side. When calculating the loading torque, the loading torque on the loading side and the loading torque on the driving side need to be calculated simultaneously.

[0046] The bench control module 130 is used to apply loads and torques to the virtual prototype based on load information and loading torque information.

[0047] Specifically, such as Figure 3 As shown in the working condition test timing diagram, after the load information and loading torque information are determined, the scheduling module 110 will send the load information and loading torque information to the bench control module 130 through the data conversion and transmission unit 212. The bench control module 130 will then apply torque and load to the virtual prototype according to the load information and loading torque information.

[0048] Specifically, the test bench control module includes a test bench and a loading system, with a virtual prototype deployed on the test bench. The test bench is used to fix, support, and connect the test platform structure of the wind turbine. The loading system applies corresponding loads and torques to the blade root, pitch loading side, towing platform, and blade hub platform of the virtual prototype based on the information contained in the load information and loading torque information. The virtual prototype is a semi-physical wind turbine model. The type of virtual prototype deployed in the test bench control module 130 changes according to the type of operating condition test being performed. In other words, different virtual prototypes are used for different operating condition tests; the same virtual prototype is not used for different operating condition tests.

[0049] The fan control module 140 is used to control the virtual prototype based on the fan operation information so that the virtual prototype outputs operating condition test information.

[0050] Specifically, such as Figure 3 The timing diagram of the test operation shown shows that after the wind turbine operation information is determined, the scheduling module 110 will send the wind turbine operation information to the wind turbine control module 140 through the data conversion and transmission unit 212; the wind turbine control module 140 will control the test wind turbine according to the wind turbine operation information, and thus obtain the test operation information output by the test wind turbine.

[0051] Specifically, the wind turbine control module 140 includes a series of control software such as main control software and pitch control software, which are configured with the actual wind farm. This allows the wind turbine control module 140 to select the corresponding control software to control each component of the virtual prototype based on the content contained in the wind turbine operation information. This enables the virtual prototype to operate based on the wind turbine operation information under the condition of applying load and torque, thereby outputting the corresponding operating condition test information.

[0052] Specifically, from Figure 3 As shown in the timing diagram of the working condition test, after each module completes the test of a working condition, it is necessary to re-query the running status of each module and perform the test of the next working condition based on the current running status of each module.

[0053] Specifically, such as Figure 2 As shown, the scheduling module 110 may also include an interface unit 216. After the scheduling module 110 obtains the working condition test information output by the virtual prototype through the data conversion and transmission unit 212, the scheduling module 110 can schedule other data analysis and processing units through the interface unit 216 to further process the working condition test information, so as to complete functions such as rain flow counting analysis, fatigue life statistics and frequency domain analysis.

[0054] Specifically, such as Figure 1 As shown, the wind turbine operating condition test platform also includes a test platform module 150, which is used to collect and upload the operating data of the scheduling module 110, simulation module 120, bench control module 130 and wind turbine control module 140 during the operating condition test.

[0055] Specifically, after the user inputs the operating condition information and the type of operating condition to be tested, the various units in the scheduling module of the wind turbine operating condition testing platform will perform calculations and schedule the simulation module, bench control module, and wind turbine control module to complete the wind turbine operating condition test based on the input operating condition information and the type of operating condition to be tested. From information input to completion of the operating condition test, the operation cycle of the wind turbine operating condition testing platform is less than 10ms.

[0056] Specifically, taking the operating condition test, which involves full IEC design conditions, wind farm load benchmarking, and pitch drivetrain component verification, as an example, this application provides a brief explanation of the wind turbine operating condition test method and the wind turbine operating condition test platform process mentioned in the implementation method. Full IEC design condition reproduction: After the scheduling module completes the preliminary data processing, it calls the simulation module to output the loads of each component of the entire unit and the actual pitch angle. The scheduling module then sends the data processing results to the test bench control module and the wind turbine control module in real time to complete the operating condition test consistent with the design wind load and control. This sampling test wind turbine scheme shortens the test cycle and identifies risks in advance. Wind Farm Load Benchmarking and Verification: Using the actual wind speed / power / load statistics of a wind farm unit as the benchmark, wind shear, turbulence intensity, and wake parameters consistent with the field are constructed. A virtual prototype consistent with the wind farm control version is deployed on a test bench to achieve repeatable reproduction and locatable attribution of field problems. Simultaneously, new functions / versions are verified on the same platform to evaluate their impact on power, load, stability, and protection actions, thereby reducing the risks and costs of direct trial and error at the wind farm. Pitch Drivetrain Component Verification: For pitch drivetrain components (such as pitch bearings, gearboxes, drives / motors), traditional testing often uses equivalent loads or fatigue / durability tests under single operating conditions, which are difficult to cover the real response under the coupling of "control command - actuator - external disturbance". This program allows for the introduction of control command sequences and external load timings (including key channels such as pitch rate, position, torque / torque, etc.) consistent with the design / field conditions into the test wind turbine on the test bench. This enables the dynamic performance and reliability verification of the pitch drive train under real control logic and external load disturbances, thereby improving the risk assessment capability throughout the entire life cycle of the component.

[0057] One embodiment of this application relates to a wind turbine operating condition testing method, which can be applied to, for example... Figure 1 The wind turbine operating condition test platform shown includes a scheduling module 110, a simulation module 120, a bench control module 130, and a wind turbine control module 140. (The text repeats itself here.) Figure 6 As shown, the wind turbine operating condition test method of this embodiment includes steps 110 to 150, each step as follows.

[0058] Step 610: Generate a wind turbine simulation model based on preset operating condition information, and generate operating condition test information based on the type of operating condition to be tested and the operating condition information.

[0059] Step 620: Real-time scheduling of the simulation module enables the simulation module to generate wind turbine operation information and load information based on the wind turbine simulation model, the operating condition test information, and the preset wind condition information.

[0060] Step 630: Generate loading torque information based on load information and preset loading type.

[0061] Step 640: Real-time scheduling of the bench control module, enabling the bench control module to apply load and torque to the virtual prototype based on load information and loading torque information.

[0062] Step 650: Real-time scheduling of the wind turbine control module, enabling the wind turbine control module to control the virtual prototype based on the wind turbine operating information, so that the virtual prototype outputs operating condition test information.

[0063] Specifically, the implementation details of steps 610-650 are the same as those of the previously mentioned scheduling module 110, simulation module 120, bench control module 130 and wind turbine control module 140, and will not be repeated here.

[0064] In the implementation of the application, the wind turbine operating condition test platform uses a scheduling module to schedule the simulation module, bench control module, and wind condition control module in real time, so as to realize real-time operating condition testing from operating condition definition, simulation calculation, load torque calculation and application to the operation and testing of the wind turbine; thereby, it can reproduce the actual operating conditions of various types of wind farms, so as to shorten the test cycle, move the risk identification node forward, and reduce the cost of on-site trial and error.

[0065] The steps described above are for clarity only. In practice, they can be combined into one step or some steps can be split into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this application. Adding insignificant modifications or introducing insignificant designs to the algorithm or process, but without changing the core design of the algorithm and process, are also within the scope of protection of this application.

[0066] Furthermore, the examples mentioned in the above embodiments can be freely combined, and any combination can be understood as an implementation method. The terms "implementation method" or "example" appearing in various locations in the specification do not necessarily refer to the same implementation method, nor are they independent or alternative implementation methods mutually exclusive with other implementation methods. Those skilled in the art will understand that the implementation methods described herein can be combined with other implementation methods.
