The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] Figure 1 is a schematic diagram of a wind turbine safety protection function testing method shown in the present application, such as Figure 1 As shown, the wind turbine generator set safety protection function testing method comprises the following steps:

[0034] S101, the main control module sends a grid connection instruction to the test module and enters the grid connection mode. The test module responds to the grid connection instruction 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.

[0035] S102, in the process of simulating the grid connection of the wind turbine generator set by the test module, modify the parameters related to the safety protection function in the test module to fault values, and monitor whether the main control module triggers a fault.

[0036] Figure 2 This is a schematic diagram of the relationship between the main control module and the test module shown in this application. Figure 2 As shown, the main control module and the test module communicate in real time through a shared address bus. The shared address bus allocates the variables required by the main control module to the shared address area, and the test module reads and feeds back the simulation parameter information in real time.

[0037] The main control module and the test module receive instructions issued by the user through the human-machine interaction interface to update the simulation parameters. For example, the user can issue a start instruction based on the human-machine interaction interface, or issue a fault value to be modified.

[0038] S103, in response to the main control module triggering a fault and entering a shutdown protection mode, the main control module sends a shutdown instruction to the test module, and the test module simulates a shutdown process of the wind turbine in response to the shutdown instruction.

[0039] 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, and the test module should simulate the shutdown process of the wind turbine based on the shutdown command (the test module simulates the shutdown process of the wind turbine according to the shutdown command, and the simulated wind turbine shutdown process includes simulating the pitch angle target value and pitch angle target rate corresponding to the shutdown issued by the main control module, simulating the blade retraction operation and simulating the deceleration operation until the unit stops and the speed is 0), and share the shutdown simulation parameters to the main control module in real time.

[0040] S104, after the test module completes the simulated wind turbine shutdown process, confirm that the test is completed and reset the main control module.

[0041] 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. It is believed that the main control module can generate a correct fault response to the unit fault.

[0042] The embodiment of the present application can effectively simulate real fault situations by modifying the safety protection related parameters in the test module to fault values, ensuring that the main control module can accurately start the protection mechanism when a fault occurs, avoiding potential equipment damage or personnel safety hazards; through systematic protection mechanism testing, it can help wind turbine manufacturers, operators and users to promptly discover the weak links and potential problems of the protection system, so as to carry out targeted optimization and improvement. This helps to reduce the frequency of fault downtime and maintenance costs, improve the overall power generation efficiency of the equipment, and increase the economic benefits of the wind farm.

[0043] Figure 3 is a schematic diagram of a wind turbine safety protection function testing method shown in the present application, such as Figure 3 As shown, the wind turbine generator set safety protection function testing method comprises the following steps:

[0044] S301, in response to the main control module detecting that the incoming flow simulated wind speed is greater than the wind speed threshold and the duration is greater than the preset duration, or in response to the main control module detecting the start-up instruction sent by the host computer, a start-up instruction is sent to the test module to enter the start-up mode, wherein the incoming flow simulated wind speed is simulated by the test module and shared with the main control module.

[0045] To facilitate the understanding of the following process and to introduce the test module more clearly, Figure 4 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 a control instruction from the main control module, each unit of the test module can generate unit operation status information according to the corresponding instruction signal and feed it back to the main control module. Among them:

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

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

[0048] v=f(V0)

[0049] Specifically, the wind speed and wind direction simulation unit generates a simulated incoming flow wind direction θ with natural fluctuation changes according to the initial wind direction value θ0 set internally or according to the initial wind direction value θ0 set by the user through the human-computer interaction interface, wherein:

[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 unit.

[0052] Specifically, according to the initial pitch angle β0 set by the test module, the given pitch angle target value β ref , the given pitch angle target rate ω sent by the main control module ref The actual pitch angle β of the unit is simulated and generated; according to the given pitch angle target value β ref and a given pitch angle target rate ω ref The simulation generates the variable pitch speed ω of the unit.

[0053] β=f(ω ref , β0, β ref )

[0054] ω=f(ω ref , β ref )

[0055] 3. The speed simulation unit is used to simulate and generate the generator simulation speed and the wind wheel simulation speed.

[0057] n gen =f(v,β,P ref )

[0058] Specifically, after the unit is started, the generator speed n generated by simulation is gen And the transmission ratio G of the transmission system is set, and the simulated speed n of the wind wheel is generated rot ,in:

[0059] n rot =f(G, n gen )

[0060] 4. The grid-connected simulation unit is used to simulate and generate grid-connected state parameters, which include grid-connected active power.

[0061] Specifically, after the unit is simulated and connected to the grid, according to the generator speed n gen , the electromagnetic torque command Te generates the unit’s grid-connected active power P.

[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, natural fluctuation vibration signals vx0 and vy0 are generated according to the initial setting 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, and the yaw-related parameters include the yaw angle.

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

[0069] Among them, after the main control module enters the startup mode, the main control module needs to send the pitch angle target value β to the test module ref , pitch angle target rate ω ref And other parameters are provided for the test module to simulate the unit startup.

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

[0071] S303, after monitoring that the startup simulation parameters meet the grid-connected conditions, the main control module sends a grid-connected instruction to the test module and enters the grid-connected mode.

[0072] Among them, after the main control module enters the grid-connected mode, the main control module needs to send electromagnetic torque instructions and other parameters to the test module for the test module to simulate the unit.

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

[0074] S305, in the process of simulating the grid connection of the wind turbine generator set by the test module, modify the parameters related to the safety protection function in the test module to the fault value, and monitor whether the main control module triggers the fault.

[0075] In some embodiments, the simulated speed of the generator corresponding to the unit in the test module is modified to a simulated speed fault value of the generator, wherein the simulated speed fault value of the generator is greater than a preset generator overspeed protection threshold; the simulated speed of the wind rotor corresponding to the unit in the test module is modified to a simulated speed fault value of the wind rotor, wherein the simulated speed fault value of the wind rotor is greater than a preset wind rotor overspeed protection threshold; after the fault value modification is completed, the main control module is monitored to see whether it triggers an overspeed protection function fault.

[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 out-of-tolerance protection threshold; after the fault value modification is completed, the main control module is monitored to see whether it triggers a blade following out-of-tolerance protection function fault.

[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 modification is completed, the main control module is monitored to see whether it triggers a vibration over-limit protection function fault.

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

[0079] Among them, four test examples are shown above. In actual application, each test may simulate only one function.

[0080] S306, in response to the main control module triggering a fault and entering a shutdown protection mode, the main control module sends a shutdown instruction to the test module, and the test module simulates the shutdown process of the wind turbine in response to the shutdown instruction.

[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, and the test module responds to the shutdown command to simulate the shutdown process of the wind turbine set. 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, confirm that the test is completed and reset the main control module.

[0083] After the test module completes the simulated wind turbine shutdown process, it confirms that the test is complete and resets the main control module. After the reset, the next functional test can be performed.

[0084] S308 , in response to the main control module not triggering a fault, confirming that the test is completed and detecting the main control module.

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

[0086] The embodiment of the present application can effectively simulate real fault situations by modifying the safety protection related parameters in the test module to fault values, ensuring that the main control module can accurately start the protection mechanism when a fault occurs, avoiding potential equipment damage or personnel safety hazards; through systematic protection mechanism testing, it can help wind turbine manufacturers, operators and users to promptly discover the weak links and potential problems of the protection system, so as to carry out targeted optimization and improvement. This helps to reduce the frequency of fault downtime and maintenance costs, improve the overall power generation efficiency of the equipment, and increase the economic benefits of the wind farm.
