Description

Technical Field

[0001] This invention relates to the field of wind power generation, and in particular to a method, apparatus, electronic device and medium for testing wind turbine generators. Background Technology

[0002] Currently, due to increasing demands for saving floor space and reducing the cost per kilowatt-hour, wind turbine capacity is gradually evolving towards larger megawatts. Correspondingly, the weight and dimensions of the blades required for installation are increasing dramatically, and the operating environment of wind turbines is becoming increasingly complex. Pitch systems, by adjusting the blade pitch angle, play a crucial role in improving captured aerodynamic power and responding to extreme weather conditions with emergency feathering. Therefore, owners are placing increasingly higher demands on the reliability and safety of the electrical commissioning of pitch systems. The ability to quickly complete the commissioning of each electrical module in the pitch system while meeting requirements for safe trial operation and rapid error troubleshooting is becoming increasingly critical to the safe and reliable operation of pitch systems in the field.

[0003] The existing pitch system commissioning involves electrical commissioning of the three sides (A, B, and C) of the shaft cabinet, one side at a time. The commissioning is mainly carried out by commissioning workers based on the factory commissioning manual and their own work experience. Due to considerations for sudden safety accidents, the commissioning is mainly carried out in pairs. One person triggers the sensors outside the hub, while the other person inside the hub uses the human-machine interface system to debug each function and records the commissioning results in the wind turbine factory commissioning manual. However, this testing method results in low efficiency and low accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a wind turbine testing method, device, electronic equipment, and medium that can perform corresponding debugging and qualification tests on the pitch system, sensor module, and blades of the wind turbine, thereby improving the accuracy and efficiency of wind turbine testing. It can also generate debugging reports based on various rated parameters, temperature parameters, preset pitch adjustment debugging results, and corresponding judgment results, making it convenient for users.

[0005] To address the aforementioned technical problems, this invention provides a wind turbine testing method, comprising:

[0006] After the wind turbine is powered on, several rated parameters of the pitch system of the wind turbine are determined, and the qualification of the pitch system is judged based on each rated parameter.

[0007] If the pitch system is qualified, after controlling the heater and heater fan of the wind turbine to turn on, determine the several temperature parameters collected by several sensor modules of the wind turbine, and determine whether each sensor module is qualified based on the collected temperature parameters.

[0008] If each of the sensor modules is qualified, then control several blades of the wind turbine to perform several preset pitch adjustment adjustments, determine the results of each preset pitch adjustment adjustment, and judge whether each blade is qualified based on the results of each preset pitch adjustment adjustment.

[0009] If each blade is qualified, a commissioning report is generated based on the rated parameters, temperature parameters, the results of the preset blade adjustment and commissioning, and the corresponding judgment results.

[0010] Optionally, determining several rated parameters of the pitch system of the wind turbine includes:

[0011] The control version, drive version, overall transmission ratio, motor type, and rated torque parameters of the pitch system are determined to obtain the rated parameters of the pitch system.

[0012] Optionally, determining the several temperature parameters collected by the several sensor modules of the wind turbine includes:

[0013] Determine the temperature parameters collected by the hub temperature sensor of the wind turbine;

[0014] Determine the temperature parameters collected by the temperature sensor of the capacitor bank of the wind turbine;

[0015] Determine the temperature parameters collected by the driver temperature sensor of the wind turbine.

[0016] Optionally, controlling several blades of the wind turbine to perform several preset blade adjustments includes:

[0017] Control each blade to perform inching adjustments based on a preset operating speed;

[0018] Control each blade to repeatedly adjust its opening and feathering within a preset angle range and a preset operating speed range;

[0019] The position of each blade is adjusted based on the preset operating speed;

[0020] Accordingly, determining the results of each of the preset pitch adjustment adjustments includes:

[0021] Determine the operating speed of each blade after the jog test;

[0022] Determine the operating speed and blade angle of each blade after the opening and feathering adjustments are performed;

[0023] Determine the blade angle of each blade after adjustment at the specified position;

[0024] Accordingly, the step of determining whether each blade is qualified based on the results of each preset blade adjustment includes:

[0025] Determine whether the running speed after the jog adjustment is equal to the first preset speed to obtain the first determination result;

[0026] Determine whether the operating speed after the adjustment of the propeller opening and feathering is within the preset operating speed range to obtain a second determination result;

[0027] The blade angles after the adjustment of the pitching and feathering are determined to be within the preset angle range, so as to obtain a third judgment result;

[0028] Determine whether the blade angle after the position adjustment is equal to the preset blade angle to obtain the fourth determination result;

[0029] Based on the first judgment result, the second judgment result, the third judgment result, and the fourth judgment result, determine whether each blade is qualified.

[0030] Optionally, before determining several rated parameters of the wind turbine's pitch system after the wind turbine is powered on, the method further includes:

[0031] Determine whether the wind turbine is powered on;

[0032] If the wind turbine is not powered on, the appearance, circuit connection, component integrity and insulation of the wind turbine are tested accordingly, and the appearance and circuit of the wind turbine are judged to be qualified based on the results.

[0033] If the appearance and circuit of the wind turbine are qualified, the step of determining several rated parameters of the pitch system of the wind turbine after it is powered on is triggered.

[0034] Optionally, after the blades are deemed qualified, the method further includes:

[0035] The oil supply capacity of the hub lights, drive fans and lubrication pump of the wind turbine is tested accordingly, and the oil supply capacity of the hub lights, drive fans and lubrication pump is judged to be qualified based on the test results.

[0036] If the oil supply capacity of the hub light, the drive fan, and the lubrication pump are all qualified, the step of generating a commissioning report based on the rated parameters, the temperature parameters, the results of the preset pitch adjustment, and the corresponding judgment results is triggered.

[0037] Optionally, after the blades are deemed qualified, the method further includes:

[0038] The lubrication pump of the wind turbine is controlled to start, and the feedback signal, oil level signal and blockage signal after the lubrication pump starts are determined. Based on the feedback signal, oil level signal and blockage signal, it is determined whether the lubrication pump is qualified.

[0039] If the lubrication pump is qualified, then control each blade to return to the initial position before the preset pitch adjustment and trigger the step of generating a debugging report based on each rated parameter, each temperature parameter, the result of the preset pitch adjustment and the corresponding judgment result.

[0040] To address the aforementioned technical problems, the present invention also provides a wind turbine testing device, comprising:

[0041] The determining unit is used to determine several rated parameters of the pitch system of the wind turbine after the wind turbine is powered on, and to determine whether the pitch system is qualified based on each rated parameter.

[0042] The first control unit is used to determine several temperature parameters collected by several sensor modules of the wind turbine after controlling the heater and heater fan of the wind turbine to turn on when the pitch system is qualified, and to determine whether each sensor module is qualified based on the collected temperature parameters.

[0043] The second control unit is used to control several blades of the wind turbine to perform several preset pitch adjustment adjustments when each of the sensor modules is qualified, and to determine the result of each preset pitch adjustment adjustment, and to determine whether each blade is qualified based on the result of each preset pitch adjustment adjustment.

[0044] The commissioning report generation unit is used to generate a commissioning report based on the rated parameters, temperature parameters, preset pitch adjustment results, and corresponding judgment results when each blade is qualified.

[0045] To address the aforementioned technical problems, the present invention also provides an electronic device, comprising:

[0049] The purpose of this invention is to provide a wind turbine testing method, device, electronic equipment, and medium. After the wind turbine is powered on, several rated parameters of the wind turbine's pitch system are first determined to determine whether the pitch system is qualified. If the pitch system is qualified, the wind turbine's heater and heater fan are turned on. Based on several temperature parameters collected by several sensor modules of the wind turbine, the qualification of each sensor module is determined. If each sensor module is qualified, several blades of the wind turbine are controlled to perform several preset pitch adjustments. Based on the results of each preset pitch adjustment, the qualification of each blade is determined. If each blade is qualified, an adjustment report is generated based on the rated parameters, temperature parameters, preset pitch adjustment results, and corresponding judgment results, thereby improving the accuracy and efficiency of wind turbine testing.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please refer to Figure 1 , Figure 1 A flowchart illustrating a wind turbine testing method provided by this invention. The method includes:

[0057] S11: After the wind turbine is powered on, determine several rated parameters of the wind turbine's pitch system, and judge whether the pitch system is qualified based on each rated parameter.

[0058] S12: If the pitch system is qualified, after the heater and heater fan of the wind turbine are turned on, determine the temperature parameters collected by several sensor modules of the wind turbine, and judge whether each sensor module is qualified based on the collected temperature parameters.

[0059] S13: If each sensor module is qualified, control several blades of the wind turbine to perform several preset pitch adjustment adjustments, determine the results of each preset pitch adjustment adjustment, and judge whether each blade is qualified based on the results of each preset pitch adjustment adjustment.

[0060] S14: If each blade is qualified, a commissioning report will be generated based on each rated parameter, each temperature parameter, the results of the preset blade adjustment and commissioning, and the corresponding judgment results.

[0061] In this invention, the pitch control system, sensor modules, and blades are debugged and tested in sequence. First, after the wind turbine is powered on, several rated parameters of the pitch control system are determined. Based on these parameters, the system's qualification is assessed. Once the pitch control system is deemed qualified, the wind turbine's heater and heater fan are activated. Based on the collected temperature parameters, the qualification of each sensor module is assessed. If each sensor module is deemed qualified, several preset pitch adjustments are performed on several blades of the wind turbine, and the results of these adjustments are determined. Based on these results, the qualification of each blade is assessed. If each blade is qualified, a debugging report is generated based on the rated parameters, temperature parameters, the preset pitch adjustment results, and the corresponding assessment results. This solution adopts a bottom-up debugging approach, first testing the basic electrical components, then sequentially debugging each single function and the functions coupled with multiple sensors. This allows for rapid fault location. After debugging is complete, a debugging report is automatically generated and uploaded to the cloud, eliminating the need for manual filling by workers, thus balancing efficiency with a more user-friendly approach.

[0062] It should be noted that, addressing the problems in existing technologies, this invention streamlines the debugging process according to electrical functional modules. Workers, using a smart debugging platform, sequentially debug the electrical modules and provide feedback on the results, eliminating the need to follow factory debugging guidelines and improving debugging efficiency. Each debugging quality control point is integrated throughout the process, and feedback on the results is required to prevent missed detections of critical quality control points. The debugging process adopts a bottom-up approach, first testing basic electrical components, then sequentially debugging individual functions and functions coupled with multiple sensors, thereby quickly pinpointing the cause of the fault. After debugging is complete, a debugging report is automatically generated and uploaded to the cloud, eliminating the need for manual filling by workers, thus combining efficiency with a more user-friendly approach.

[0063] It should also be noted that the following pre-commissioning requirements must be met: 1. Technical preparation: Verify the electrician's operating certificate of the commissioning personnel to ensure they are certified and qualified. Before commissioning, all commissioning personnel should receive training on safety precautions, quality control points, and the intelligent commissioning platform. Commissioning personnel should install the intelligent commissioning platform and familiarize themselves with electrical drawings and relevant electrical component technical data. 2. Preparation of commissioning equipment, instruments, and materials. 3. Commissioning environment requirements: The inside of the wheel hub should be free of debris and obvious lubricating oil stains, and the cable wiring between all electrical components should be completed. There should be no operating hoisting equipment above the wheel hub, and a "Working in Progress" sign should be placed around it. 4. Safety technical requirements: Cables should be placed in areas not accessible to engineering vehicles to prevent them from being run over. Power outages and restorations must be confirmed with the commissioning personnel inside the wheel hub. Before commissioning begins, ensure that the factory's fire alarm system is functioning properly.

[0064] This embodiment provides a wind turbine testing method. After the wind turbine is powered on, several rated parameters of the wind turbine's pitch system are first determined to determine whether the pitch system is qualified. If the pitch system is qualified, the wind turbine's heater and heater fan are turned on. Based on several temperature parameters collected by several sensor modules of the wind turbine, the qualification of each sensor module is determined. If each sensor module is qualified, several blades of the wind turbine are controlled to perform several preset pitch adjustments. Based on the results of each preset pitch adjustment, the qualification of each blade is determined. If each blade is qualified, an adjustment report is generated based on the rated parameters, temperature parameters, preset pitch adjustment results, and corresponding judgment results, thereby improving the accuracy and efficiency of wind turbine testing.

[0065] Based on the above embodiments:

[0066] As an optional embodiment, several rated parameters of the wind turbine's pitch system are determined, including:

[0067] Determine the control version, drive version, overall transmission ratio, motor type, and rated torque parameters of the pitch system to obtain the rated parameters of the pitch system.

[0068] In this invention, several rated parameters of the pitch system include control version, drive version, total transmission ratio, motor type, and motor rated torque parameters. These parameters need to be determined first in order to accurately perform the subsequent pitch system qualification judgment process, thus ensuring the integrity of the solution.

[0069] As an optional embodiment, several temperature parameters collected by several sensor modules of the wind turbine are determined, including:

[0070] Determine the temperature parameters collected by the hub temperature sensor of the wind turbine;

[0071] Determine the temperature parameters collected by the temperature sensor of the capacitor bank of the wind turbine;

[0072] Determine the temperature parameters collected by the driver temperature sensor of the wind turbine.

[0073] In this invention, the temperature parameters collected by several sensor modules of the wind turbine include: temperature parameters collected by the hub temperature sensor, temperature parameters collected by the capacitor bank temperature sensor, and temperature parameters collected by the drive temperature sensor. Therefore, it is necessary to determine these parameters in order to accurately perform the subsequent sensor module qualification judgment process and ensure the integrity of the solution.

[0074] As an optional embodiment, controlling several blades of the wind turbine to perform several preset pitch adjustment adjustments includes:

[0075] Control each blade to perform inching adjustments based on the preset operating speed;

[0076] Control each blade to repeatedly adjust its opening and feathering within a preset angle range and a preset operating speed range;

[0077] The position of each blade is adjusted based on the preset operating speed;

[0078] Accordingly, the results of each preset pitch adjustment are determined, including:

[0079] Determine the operating speed of each blade after jogging adjustment;

[0080] Determine the operating speed and blade angle of each blade after adjusting for opening and feathering;

[0081] Determine the blade angles of each blade after position adjustment;

[0082] Accordingly, based on the results of each preset pitch adjustment test, the qualification of each blade is determined, including:

[0083] Determine whether the running speed after jogging adjustment is equal to the first preset speed to obtain the first judgment result;

[0084] Determine whether the operating speed after the pitching and feathering adjustments is within the preset operating speed range to obtain a second determination result;

[0085] The third judgment result is obtained by determining that the blade angles after adjustment for both pitching and feathering are within the preset angle range.

[0086] Determine whether the blade angle after position adjustment is equal to the preset blade angle to obtain the fourth judgment result;

[0087] The first, second, third, and fourth judgment results are used to determine whether each blade is qualified.

[0088] In this invention, the specific process of controlling several blades of a wind turbine to perform several preset pitch adjustment adjustments is as follows: Each blade is controlled to perform jogging adjustments based on a preset operating speed; each blade is controlled to repeatedly open and feather within a preset angle and operating speed range; and each blade is controlled to perform position adjustments based on a preset operating speed. After completing the above control, the blade's qualification can be judged based on the determined operating speed of each blade after jogging adjustments, the operating speed and blade angle after opening and feathering adjustments, and the blade angle after position adjustments. The system obtains a first judgment result by determining whether the running speed after jogging adjustment is equal to the first preset speed; a second judgment result by determining whether the running speed after pitching and feathering adjustments is within the preset running speed range; a third judgment result by determining whether the blade angle after pitching and feathering adjustments is within the preset angle range; and a fourth judgment result by determining whether the blade angle after position adjustment is equal to the preset blade angle. This facilitates subsequent judgment of whether each blade is qualified based on the first, second, third, and fourth judgment results, thus improving the accuracy of the solution.

[0089] As an optional embodiment, before determining several rated parameters of the wind turbine's pitch system after the wind turbine is powered on, the method further includes:

[0090] Determine if the wind turbine is powered on;

[0091] If the wind turbine is not powered on, the appearance, circuit connection, component integrity and insulation of the wind turbine shall be tested accordingly, and the appearance and circuit of the wind turbine shall be judged as qualified based on the results.

[0092] If the appearance and circuit of the wind turbine are qualified, the steps of determining several rated parameters of the wind turbine's pitch system after the wind turbine is powered on are triggered.

[0093] In this invention, before determining several rated parameters of the wind turbine's pitch system after it is powered on, it is possible to determine whether the wind turbine is powered on. If the wind turbine is not powered on, corresponding tests are performed on its appearance, circuit connections, component integrity, and insulation. Based on the results, it is determined whether the wind turbine's appearance and circuit are qualified. Conversely, if the wind turbine's appearance and circuit are qualified, the step of determining several rated parameters of the wind turbine's pitch system after it is powered on is triggered. This solution enables the determination of the wind turbine's appearance and circuit qualification when it is not powered on, improving the accuracy of the test.

[0094] As an optional embodiment, after each blade has passed inspection, the method further includes:

[0095] The oil supply capacity of the hub lights, drive fans and lubrication pumps of the wind turbine is tested accordingly, and the oil supply capacity of the hub lights, drive fans and lubrication pumps is judged to be qualified based on the test results.

[0096] If the oil supply capacity of the hub lights, drive fan, and lubrication pump are all qualified, the step of generating a commissioning report based on the rated parameters, temperature parameters, preset pitch adjustment results, and corresponding judgment results is triggered.

[0097] In this invention, after determining that each blade is qualified, the oil supply capacity of the hub lights, drive fans, and lubrication pumps of the wind turbine can be tested accordingly. Based on the test results, it is determined whether the oil supply capacity of the hub lights, drive fans, and lubrication pumps is qualified. If the oil supply capacity of the hub lights, drive fans, and lubrication pumps is qualified, the step of generating a commissioning report based on each rated parameter, each temperature parameter, the preset pitch adjustment result, and the corresponding judgment result is triggered. This solution can realize the judgment of the qualification of the oil supply capacity of the hub lights, drive fans, and lubrication pumps, thus improving the accuracy of the test.

[0098] As an optional embodiment, after each blade has passed inspection, the method further includes:

[0099] Control the start of the lubrication pump of the wind turbine, and determine the feedback signal, oil level signal and blockage signal after the lubrication pump starts. Based on the feedback signal, oil level signal and blockage signal, determine whether the lubrication pump is qualified.

[0100] If the lubrication pump is qualified, control each blade to return to the initial position before the preset pitch adjustment and trigger the step of generating a commissioning report based on each rated parameter, each temperature parameter, the result of the preset pitch adjustment and the corresponding judgment result.

[0101] In this invention, after determining that each blade is qualified, the lubrication pump of the wind turbine can be started by controlling the start of the lubrication pump. The feedback signal, oil level signal and blockage signal after the lubrication pump starts can be determined. Based on the feedback signal, oil level signal and blockage signal, the qualification of the lubrication pump can be determined. After determining that the lubrication pump is qualified, each blade is controlled to return to the initial position before the preset pitch adjustment and debugging, so as to ensure the consistency of the blade position before and after the test. This solution can realize the qualification of the lubrication pump and improve the accuracy of the test.

[0102] It should be noted that the testing process for this invention can be summarized in the following order: a. Electrical equipment installation; b. Commissioning workers entering the factory; c. Pre-power-on inspection; d. System power-on; e. Pitch system parameter verification; f. Sensor module testing; g. Pitch control module commissioning; h. Auxiliary module testing; i. Lubrication module testing; j. Pitch system reset; k. Generating a commissioning report. The entire process is as follows: Figure 2 As shown. Electrical equipment installation refers to the sequential installation of equipment on the A, B, and C sides of the shaft cabinet, including the shaft cabinet itself, controller, limit switches, proximity switches, pitch motor, lubrication pump, etc., as well as the corresponding cable laying. After installation, a quality engineer conducts a specialized quality self-inspection. Commissioning worker entry refers to the allocation of commissioning accounts and login to the intelligent commissioning platform. The intelligent commissioning platform includes detailed steps and quality control points for different commissioning modules, as well as feedback on test results after the commissioning items are completed.

[0103] It should also be noted that the pre-power-on inspection includes three aspects: visual inspection, circuit calibration, and insulation calibration. This ensures that no electrical components are missing, confirms that the components installed in the shaft cabinet are secure, that the relays and base connections are secure, that the limit switches are correctly connected to the shaft cabinet, that the pitch motor is correctly connected to the shaft cabinet, that the driver and terminal cable connections are secure, that there are no loose pins on the heavy-duty plug, performs insulation testing on critical circuits, measures the pitch motor circuit, disconnects all switches in the cabinet, and feeds the debugging data back to the intelligent debugging platform. If the test items pass, proceed to the next module for debugging.

[0104] It should also be noted that when the system is powered on, the phase voltage and line voltage of the power supply need to be measured to see if they are within the marked range. After checking that they are within the correct range, the A, B, and C sides of the shaft cabinet are closed and powered on in sequence. The debugging data is fed back to the intelligent debugging platform. If the test item is qualified, the next module is debugged.

[0105] It should also be noted that the pitch system parameters are checked, including the control version, drive version, total transmission ratio, motor type, and rated torque parameters of the wind turbine single-drive pitch system. The debugging data is then fed back to the intelligent debugging platform. If the test item is qualified, the next module debugging is carried out.

[0106] It should also be noted that the sensor module test includes testing the heater fan, the heater, the wheel hub temperature sensor, the capacitor bank temperature sensor, and the driver temperature sensor. The proximity switch and limit switch are manually triggered in sequence for functional testing. The debugging data is fed back to the intelligent debugging platform. If the test item is qualified, the next module is debugged.

[0107] It should also be noted that the pitch control module debugging includes three modes: jog control debugging, interval control debugging, and position control debugging. The self-learning module is then debugged, and the debugging data is fed back to the intelligent debugging platform. If the test item passes, the next module debugging is performed. Jog control testing requires jogging at a given operating speed while observing the actual speed. Interval control testing requires inputting an angle range and operating speed range to perform back-and-forth pitching and feathering tests. Position control testing requires inputting a specified angle and operating speed, and at a given operating speed, the blades must open and close to the specified angle.

[0108] It should also be noted that auxiliary module debugging, including debugging of hub lights, drive fans, lubrication pump oil supply, etc., feeds the debugging data back to the intelligent debugging platform. If the test item passes, the next module debugging will proceed.

[0109] It should also be noted that the lubrication module debugging includes starting and running the lubrication pump, and testing the lubrication pump feedback signal, oil level signal, and lubrication pump blockage signal in sequence. The debugging data is then fed back to the intelligent debugging platform. If the test item passes, the next module debugging is performed.

[0110] It should also be noted that after the above debugging is completed, the pitch system needs to be reset, that is, the blades on all three sides of the shaft cabinet (A, B, and C) should be returned to the shipping position, the backup power switch and the main switch should be turned off, and the cabinet door should be sealed after checking that no tools are left inside. Furthermore, the intelligent debugging platform can automatically generate a debugging report based on the debugging results fed back from each debugging module.
