In recent years, wind power technology has continued to advance, the single-unit capacity of wind turbines has been increasing, structural designs have become more complex, and operating environments and workloads have become more diverse. To adapt to different wind energy resources and complex climate conditions, modern wind turbines need to have efficient and stable operating performance. However, because wind turbines operate under high loads and harsh conditions, the equipment is prone to failure during long-term operation, which may not only lead to equipment damage but also pose a threat to the safety of on-site personnel.

At the same time, the protection mechanisms of wind turbines must also be able to adapt to various changes in operating conditions, improve operational reliability, and reduce downtime and maintenance costs.

[0045] To facilitate understanding of the following process, and to more clearly introduce the test module, Figure 4 This is a schematic diagram of a test module shown in this application, such as... Figure 4 As shown, the test module includes a wind speed and direction simulation unit, a pitch simulation unit, a speed simulation unit, a grid connection simulation unit, a vibration simulation unit, and a yaw simulation unit. When the test module receives control commands from the main control module, each unit of the test module can generate unit operating status information according to the corresponding command signals and feed it back to the main control module. Among them:

[0046] 1. The wind speed and direction simulation unit is used to simulate and generate the incoming wind speed and direction.

[0047] Specifically, the wind speed and direction simulation unit generates a simulated incoming wind speed v with natural fluctuations, based on its internally set initial wind speed value V0 or the initial wind speed value V0 set by the user through the human-computer interaction interface, where:

[0048] v = f(V0)

[0049] Specifically, the wind speed and direction simulation unit generates a simulated incoming wind direction θ with natural fluctuations, based on its internally set initial wind direction value θ0 or the initial wind direction value θ0 set by the user through the human-computer interaction interface.

[0050] θ=f(θ0)

[0051] 2. The pitch simulation unit is used to simulate and generate the real-time pitch angle and real-time pitch speed of the generator set.

[0061] Specifically, after the unit simulates grid connection, based on the generator speed n gen The electromagnetic torque command Te generates the grid-connected active power P of the generator unit.

[0062] P = f(n) gen Te)

[0063] 5. The vibration simulation unit is used to simulate and generate vibration-related parameters of the unit, including vibration acceleration values.

[0064] Specifically, vibration signals vx0 and vy0 with natural fluctuations are generated based on the initial set values ​​Vx0 and Vy0 of the unit vibration.

[0065] vx0=f(Vx0)

[0066] vy0=f(Vy0)

[0067] 6. The yaw simulation unit is used to simulate and generate the yaw-related parameters of the unit, including the yaw angle.

[0068] When the simulated wind turbine is in standby mode, the main control module needs to determine whether the simulated incoming wind speed generated by the wind speed simulation unit has been continuously exceeding a predetermined time and is higher than the start-up wind speed threshold, or whether a start-up command has been received from the host computer. If the main control module detects that the duration of the simulated incoming wind speed being greater than the wind speed threshold is longer than the preset duration, or if the host computer issues a start-up command, it sends a start-up command to the test module, at which point the main control module enters start-up mode.

[0069] After entering startup mode, the main control module needs to send the target pitch angle β to the test module. ref Target speed ω of propeller pitch angle ref These parameters are used by the test module to simulate unit startup.

[0070] S302, the test module responds to the start command to simulate the wind turbine start-up process and shares the start-up simulation parameters with the main control module in real time.

[0071] S303: After the main control module detects that the startup simulation parameters meet the grid connection conditions, it sends a grid connection command to the test module and enters the grid connection mode.

[0072] After entering grid-connected mode, the main control module needs to send electromagnetic torque commands and other parameters to the test module for the test module to perform unit simulation.

[0073] S304, the test module responds to the grid connection command to simulate the grid connection process of the wind turbine, and shares the grid connection simulation parameters with the main control module in real time.

[0074] S305, during the process of simulating wind turbine grid connection in the test module, modifies the relevant parameters of the safety protection function in the test module to fault values ​​and monitors whether the main control module triggers a fault.

[0075] In some embodiments, the simulated generator speed corresponding to the unit in the test module is modified to a generator simulated speed fault value, wherein the generator simulated speed fault value is greater than a preset generator overspeed protection threshold; the simulated wind turbine speed corresponding to the unit in the test module is modified to a wind turbine simulated speed fault value, wherein the wind turbine simulated speed fault value is greater than a preset wind turbine overspeed protection threshold; after the fault value is modified, the main control module is monitored to see if the overspeed protection function fault is triggered.

[0076] In some embodiments, the real-time pitch angle of any blade of the unit in the test module is modified to a pitch angle fault value, wherein the difference between the pitch angle fault value and the real-time pitch angle of the blade is greater than a preset blade following over-tolerance protection threshold; after the fault value is modified, the main control module is monitored to see if the blade following over-tolerance protection function is triggered.

[0077] In some embodiments, the vibration acceleration value of the unit in any direction in the test module is modified to a vibration acceleration fault value, wherein the vibration acceleration fault value is greater than a preset unit vibration over-limit protection threshold; after the fault value is modified, the main control module is monitored to see if the vibration over-limit protection function is triggered.

[0078] In some embodiments, the yaw angle (the angle between the wind turbine rotor or the main shaft of the wind turbine and the wind direction) corresponding to the unit in the test module is modified to the yaw angle fault value, wherein the yaw angle fault value is greater than the preset yaw over-limit protection threshold; after the fault value is modified, the main control module is monitored to see if the yaw over-limit protection function is triggered.

[0079] The above examples illustrate four test scenarios. In practical applications, each test may simulate only one function.

[0080] S306, in response to the main control module triggering a fault and entering the shutdown protection mode, sends a shutdown command to the test module based on the main control module, and the test module responds to the shutdown command to simulate the shutdown process of the wind turbine.

[0081] For any of the functional tests shown above, if the main control module triggers a fault and enters the shutdown protection mode, the main control module sends a shutdown command to the test module. The test module responds to the shutdown command to simulate the wind turbine shutdown process. At this time, it is considered that the main control module can generate a correct fault response to the unit fault.

[0082] S307: After the test module completes the simulated wind turbine shutdown process, it confirms the test is complete and resets the main control module.

[0083] After the test module completes the simulated wind turbine shutdown process, the test is confirmed to be complete and the main control module is reset. The next functional test can then be performed after the reset.

[0084] S308, in response to the main control module not triggering a fault, confirms the test is complete and performs a test on the main control module.

[0085] If the main control module does not trigger a fault, it indicates that there may be some problems with the main control module that cannot be detected in time, so the main control module needs to be tested.

[0086] This application's embodiments, by modifying the safety protection-related parameters in the test module to fault values, effectively simulate real-world fault scenarios. This ensures that the main control module can accurately activate the protection mechanism when a fault occurs, avoiding potential equipment damage or personnel safety hazards. Through systematic protection mechanism testing, wind turbine manufacturers, operators, and users can promptly identify weaknesses and potential problems in the protection system, enabling targeted optimization and improvements.
