Description

Technical Field

[0001] This disclosure generally relates to the field of wind power generation technology, and more specifically to methods for testing wind turbine generators and computer-readable storage media. Background Technology

[0002] Currently, monitoring the operational status of lubrication equipment is crucial for ensuring timely lubrication of wind turbines during operation, reducing mechanical wear, guaranteeing stable operation of wind turbine units, and minimizing unit lifespan loss. However, lubrication equipment typically uses a progressive distributor for grease filling. Therefore, the proximity switch used to detect the lubrication pump's operation generates alternating high and low level signals. To detect these changes, the lubrication pump needs to run for a relatively long time, resulting in the injection of a larger amount of grease during the testing process. Repeated test runs will inject even more grease. On one hand, the lubrication pump's oil storage capacity is relatively small, and repeated grease injections lead to a relatively high grease loss rate. On the other hand, repeated grease injections can easily cause over-lubrication of rotating parts, leading to increased bearing temperature or damage to rotating components. Summary of the Invention

[0021] According to the wind turbine generator testing method and computer-readable storage medium of the embodiments of this disclosure, before each testing of the lubrication equipment, the testing information of the previously tested equipment is queried. This allows the system to refer to the previous testing information before testing the lubrication equipment to determine whether to test it again, thereby avoiding repeated testing of the lubrication equipment. This reduces the running time of the lubrication pump and the amount of lubricating grease added, preventing high lubricating grease loss and over-lubrication of wind turbine generator components. Therefore, this disclosure effectively solves the problem of excessive grease addition in the prior art.

[0037] Furthermore, in the description of the examples, detailed descriptions of well-known related structures or functions will be omitted when it is believed that such detailed descriptions would lead to a vague interpretation of this disclosure.

[0038] Currently, lubrication equipment generally uses a progressive distributor for grease filling. Therefore, the proximity switch used to detect the lubrication pump's operation sends alternating high and low level signals. To detect these changes, the lubrication pump needs to run for a relatively long time, resulting in a large amount of grease being injected during the testing process. If the test is repeated multiple times, even more grease will be injected. On one hand, wind turbine lubrication pumps have relatively small oil storage capacity, and multiple injections lead to a relatively high rate of grease loss. On the other hand, this method is highly unpredictable, potentially leading to multiple tests without proper guidance. Excessive grease injection during these tests can easily cause over-lubrication of rotating parts.

[0039] According to the lubrication mechanism, the viscosity of lubricating grease directly affects the formation of the lubricating oil film. Specifically, under the same rotational speed and load, higher viscosity lubricating grease is more conducive to the formation of a lubricating oil film. Therefore, many people easily conclude that the higher the viscosity of lubricating grease, the better. However, in reality, as the viscosity of lubricating grease increases, the motion resistance of rolling elements on the raceway surface also increases. This leads to an increase in the torque resisting the operation of bearings, etc. Therefore, excessively high viscosity of lubricating grease, i.e., "over-lubrication," may cause damage to rotating parts or bearings, resulting in two main disadvantages:

[0040] 1) The high viscosity of the lubricating grease creates resistance torque, which is ultimately dissipated as heat during bearing rotation. Therefore, high lubricating grease viscosity leads to an increase in bearing temperature. In engineering practice, there have even been cases where high lubricating grease viscosity caused grease clumping, preventing the grease from effectively entering the rolling elements and raceways to form an oil film.

[0041] 2) When the rotating parts are running, the rolling elements have a certain stirring effect on the lubricating grease. If the lubricating grease is always full inside the rotating parts, this stirring will also increase the running torque of the rotating parts, which will cause the rotating parts to heat up and even damage the rotating parts.

[0042] To address the aforementioned problems, this disclosure provides a method and apparatus for detecting wind turbine generator sets, as well as a computer-readable storage medium, which can solve the problems. The detection method for wind turbine generator sets disclosed herein can be applied to a server and a controller. The server can be a computer that directly issues control commands, such as a personal computer (PC), host computer, upper computer, server cluster, etc. The upper computer is generally a computer with a monitor; in this disclosure, the upper computer can be an industrial control computer. The controller can be the controller of a single wind turbine generator or the main controller of a wind farm; this disclosure does not limit this. The controller can be a programmable logic controller (PLC) or a microcontroller; this disclosure does not limit this. The server, controller, and wind turbine generator set can be connected wirelessly or via a wired connection; this is not limited here. The following explanation uses the upper computer as the server as an example.

[0043] When the controller detects that the current test item of the wind turbine generator set is associated with the lubrication equipment, it sends a request to the host computer to obtain the detection information of the lubrication equipment's previous tests. The host computer, in response to receiving the request from the wind turbine generator set's controller, queries the detection information. If the retrieved detection information indicates that the lubrication equipment's test data is greater than a predetermined threshold and the time of the previous test is consistent with the current time, it obtains the detection result of the previous test of the lubrication equipment and sends the result to the controller. The controller receives the detection result of the previous test of the lubrication equipment from the host computer. If the detection result indicates that the lubrication equipment is operating abnormally, it re-tests the lubrication equipment. After the lubrication equipment test is completed, it tests other test items of the wind turbine generator set; if the detection result indicates that the lubrication equipment is operating normally, it directly tests other test items of the wind turbine generator set.

[0044] The following describes in detail, with reference to the accompanying drawings, the testing method and apparatus for wind turbine generator sets, and the computer-readable storage medium of this disclosure.

[0045] This disclosure proposes a testing method for wind turbine generator sets. Figure 1 This is a flowchart illustrating a method for testing wind turbine generator sets according to an embodiment of the present disclosure. Figure 1 . Reference Figure 1 The testing method for the wind turbine generator set includes the following steps:

[0046] In step S101, in response to receiving a request from the controller of the wind turbine generator set for obtaining detection information of previous detections of the lubrication equipment of the wind turbine generator set, the detection information is queried.

[0047] The execution entity of this step can be a server, which can be a computer that directly issues control commands, such as a personal computer, host computer, or supervisory control system. The controller mentioned above can be the controller of the wind turbine generator main control system, the controller of the pitch system, or the main controller of the wind farm; this disclosure does not limit its scope. The controller mentioned above can be a programmable logic controller (PLC) or a microcontroller; this disclosure does not limit its scope. The detection information of the previous detection may include, but is not limited to: the detection result of the previous detection, the duration of the previous detection, and the time of the previous detection. The previous detection can be the last detection or the two previous detections; this disclosure does not limit its scope.

[0048] As an example, taking the host computer as the executing entity, combined with Figure 2A brief explanation of the overall testing process for wind turbine generator sets is provided below. After the host computer initiates the testing of the wind turbine generator set, it will interact with the controller to perform data testing on the wind turbine generator set. Specifically, as follows... Figure 2 As shown, after the host computer submits the testing configuration information for the wind turbine generator set, it notifies the controller to start the automatic testing process for the wind turbine generator set. Assuming the wind turbine generator set needs to be tested for N items, the testing process can be a sequential state check of each item from 1 to N. Since the testing conditions for each item are different, it is necessary to first confirm the item to be tested, and then determine whether the testing conditions meet the requirements. If the result does not meet the requirements, the process returns to the step of reconfirming the item until the testing conditions meet the requirements. If the result meets the requirements, the item is tested, and after the item is tested, the test sequence number is incremented by 1, and the next item is tested. This continues until all items are tested and all pass, at which point a test report can be output. Otherwise, no test report is output. The factory testing requirement is that all tests are completed and a test report is generated.

[0049] The aforementioned testing process for wind turbine generators may include, but is not limited to, the testing items shown in Table 1. Generally, multiple testing runs do not affect the equipment. However, if the lubrication equipment is run multiple times and there are a large number of lubrication pumps, it will prolong the testing time. Furthermore, unexpected interruptions to the testing process (such as time constraints, abnormal exit of the host computer, or multiple test verifications) will result in multiple, repetitive tests, leading to a certain degree of grease waste and over-lubrication of rotating parts. To avoid this situation and ensure the accuracy of the test results, this disclosure allows the host computer to respond to a request received from the wind turbine generator controller to obtain previous testing information of the lubrication equipment during the testing process. This allows the host computer to query the previous testing information of the lubrication equipment and subsequently determine whether to retest the lubrication equipment based on this information.

[0050] Table 1 Test Items

[0051]

[0052]

[0053] According to embodiments of this disclosure, before receiving a request from the wind turbine controller for obtaining previous detection information of the wind turbine's lubrication equipment, the local detection configuration information of the wind turbine can be removed; updated detection configuration information of the wind turbine input by the user can be received; based on the latest detection configuration information, start-up information for instructing the controller to begin detecting the wind turbine can be sent. According to this embodiment, each time the server restarts, it automatically removes the local detection configuration information and waits for the user to input the latest detection configuration information. That is, the user needs to resubmit the detection configuration information before the detection process of the wind turbine can be started. This ensures that the detection configuration information of the wind turbine is the correct detection configuration information required each time, avoiding subsequent judgment errors due to incorrect detection configuration information.

[0054] As an example, taking the server as the host computer, each time the host computer restarts, it can automatically remove the local detection configuration information. Then, the user fills in the latest detection configuration information and submits it (i.e., the updated detection configuration information mentioned above). Only then is the start information for instructing the controller to start detecting the wind turbine generator set sent to the controller to initiate the detection process. If the latest detection configuration information filled in by the user is not detected, the start information for instructing the controller to start detecting the wind turbine generator set is not sent, that is, the detection process for the wind turbine generator set is not initiated. This ensures that the latest detection configuration information is used in each detection process, avoiding the use of incorrect information. For example, taking the detection time as an example, assuming the current time is 8:00 AM today, if you want to detect the wind turbine at 8:00 AM the next day, but you haven't removed the local detection configuration information and haven't entered the latest detection configuration information, then since there is no latest detection configuration information, when using the detection configuration information, it may use the original detection configuration information (i.e., the detection configuration information that was not removed above), that is, the detection of the wind turbine will start from the time in the original detection configuration information. Another possibility is that the local detection configuration information has been removed, but no latest detection configuration information has been entered. In this case, since there is neither the latest detection configuration information nor the original detection configuration information, it is very likely that when the host computer detects the current time, it is 8:00 AM today, and the wind turbine will be detected at 8:00 AM today, not at 8:00 AM the next day.

[0055] According to embodiments of this disclosure, the querying of detection information in step S101 may include, but is not limited to: determining the turbine number of the wind turbine generator set and the equipment number of the lubrication equipment based on the request message; and querying the previous detection information of the lubrication equipment of the wind turbine generator set from memory based on the turbine number and the equipment number. According to this embodiment, by using the turbine number and the equipment number, the correctly corresponding previous detection information can be conveniently and quickly queried, avoiding the querying of incorrect detection information.

[0056] For example, taking the server as the host computer, assuming that the lubrication equipment has been tested and the corresponding test information has been stored, before testing the lubrication equipment again, the system can quickly query the previous test information of the lubrication equipment from the local memory based on the unit number of the wind turbine and the equipment number of the lubrication equipment, and read the corresponding content in the test information to determine whether to test the lubrication equipment again.

[0057] In step S102, in response to the detection information indicating that the detection data of the lubrication device is greater than a predetermined threshold and the previous detection time of the lubrication device is consistent with the current time, the detection result of the previous detection of the lubrication device is obtained and sent to the controller so that the controller can determine whether to detect the lubrication device again based on the detection result.

[0058] In this step, the detection data can be the number of tests. The predetermined threshold can be set as needed, such as 1, meaning that obtaining the detection result is only meaningful if the number of tests on the lubrication equipment is greater than 1. Otherwise, if the lubrication equipment has never been tested, the detection result may be empty, making the operation of obtaining the detection result meaningless. The detection data in this step can also be the detection enable, and the predetermined threshold can also be set as needed. For example, setting the detection enable to 0 indicates that the scheme of this disclosure is not enabled, while setting the detection enable to 1 (i.e., greater than 0) indicates that the scheme of this disclosure is enabled. That is, if the detection enable is greater than 0, the detection result will be obtained; otherwise, no detection result will be obtained. The detection data in this step can also be other content, which is not limited in this disclosure.

[0059] It should be noted that the server can also determine whether the lubrication equipment is operating normally or abnormally based on the detection results. If the lubrication equipment is determined to be operating normally, the server can directly send a "detected flag" to the controller, and the controller will not perform another detection on the lubrication equipment. If the lubrication equipment is determined to be operating abnormally, the server can notify the controller to perform another detection on the lubrication equipment.

[0060] As an example, still using the server as the host computer, when the controller of the wind turbine receives a request to obtain the detection information of the previous detection of the lubrication equipment of the wind turbine, the host computer reads the information in memory. If the unit number, the time of the previous detection of the lubrication equipment in memory are consistent with the information currently submitted by the host computer, and the detection result in memory shows that the lubrication equipment is operating normally, and the number of process detections in memory is greater than 1, then the host computer sends a "detected flag" to the controller. At this time, the lubrication equipment will not be detected again, in order to reduce the running time of the lubricating oil pump and reduce the lubrication and grease filling time. If one of the above conditions is not met, the server can notify the controller to detect the lubrication equipment again.

[0061] According to embodiments of this disclosure, whether the previous detection time and the current time of the lubrication device are consistent can be determined in the following manner: the previous detection time and the current time are on the same date; and a predetermined time interval exists between the previous detection time and the current time. According to this embodiment, the consistency between the previous detection time and the current time can be flexibly determined according to the user's needs.

[0062] Specifically, the predetermined time interval between the previously detected time and the current time can be two time intervals of a predetermined number of days, or two times on the same date, but with a predetermined number of hours between the two time intervals; this disclosure does not limit this. The aforementioned "same date" can be the same day or the same hour; this disclosure does not limit this either.

[0063] As an example, taking the detection data as the number of detections, the predetermined threshold as 1, and the two times as the same date, when the queried detection information indicates that the number of detections of the lubrication equipment is greater than 1, and the time of the previous detection of the lubrication equipment is on the same date as the current time, the detection result of the previous detection of the lubrication equipment is obtained and sent to the controller so that the controller can determine whether to detect the lubrication equipment again based on the detection result.

[0064] According to embodiments of this disclosure, in response to a detection information indicating that the detection data of the lubrication device exceeds a predetermined threshold and the previous detection time of the lubrication device is consistent with the current time, the detection duration of the previous detection of the lubrication device can be obtained and sent to the controller, so that the controller can determine whether to re-detect the lubrication device based on the detection result and the detection duration. According to this embodiment, the determination of whether to re-detect the lubrication device can be made by combining the detection duration and the detection result. This avoids making the erroneous decision not to re-detect the lubrication device when the detection result indicates that the lubrication device is operating normally but the detection process is incorrect.

[0065] As an example, assuming the detection data is the number of tests, the predetermined threshold is 1, and the two times are on the same date, if the queried detection information indicates that the number of tests on the lubrication equipment is greater than 1, and the time of the last test on the lubrication equipment is on the same date as the current time, then the detection result and duration of the previous test on the lubrication equipment are obtained and sent to the controller. The controller can then determine whether to re-test the lubrication equipment based on the detection result and duration. For example, if the previous detection result indicates that the lubrication equipment is operating normally, but the duration of the previous test was too short, such as the running time of the lubrication pump being too short, then the lubrication equipment also needs to be re-tested, i.e., the lubrication pump is restarted for testing, to ensure the accuracy of the test and the quality of the finished product.

[0066] According to embodiments of this disclosure, in response to a detection information indicating that the detection data of the lubrication device is greater than a predetermined threshold and that the previous detection time of the lubrication device is inconsistent with the current time, the previous detection time of the lubrication device can be obtained and sent to the controller, so that the controller can determine to re-detect the lubrication device based on the previous detection time. According to this embodiment, when the previous detection time is inconsistent with the current time, the previous detection time can be sent to the controller, so that the controller can directly determine to re-detect the lubrication device based on the previous detection time.

[0067] As an example, taking the detection data as the number of detections, the predetermined threshold as 1, and the two times as the same date, when the queried detection information indicates that the number of detections of the lubrication equipment is greater than 1, and the time of the previous detection of the lubrication equipment is not on the same date as the current time, the previous detection time of the lubrication equipment is obtained, and the previous detection time is sent to the controller. The controller can directly detect the lubrication equipment again based on the previous detection time.

[0068] According to embodiments of this disclosure, after sending the detection result to the controller, the current detection result and / or current detection duration of the lubrication device can be received from the controller; the positions of the detection result and / or detection duration and the detection time of the lubrication device in memory can be determined; and the positions can be overwritten using the current detection result and / or current detection duration and the current time. According to this embodiment, after receiving the current detection result and detection duration, the original detection result and detection duration in memory can be quickly updated by overwriting, facilitating subsequent detections to read the latest information.

[0069] Specifically, after the controller completes a re-inspection of the lubrication equipment, it can transmit the current inspection results and inspection duration to the server. The server stores this new data, which can be used to overwrite the original memory location where this type of data was stored, thus updating the data. Additionally, the inspection time can be updated simultaneously for status reading and judgment during the next inspection. It should be noted that if the controller does not re-inspect the lubrication equipment, it will not transmit any information to the server. That is, if the server does not receive any feedback, it will not update any information, such as the inspection time, thus ensuring the timeliness of the inspection cycle. For example, if the controller does not re-inspect the lubrication equipment after a previous inspection, and the server does not re-store any data, then if an excessively long interval (e.g., 2 days) is required before re-inspection, the system will automatically determine that the inspection time in memory is inconsistent with the current time. In this case, the lubrication pump needs to be restarted for inspection to prevent abnormal changes in the wiring during a long period of inactivity from affecting the lubrication equipment (e.g., wiring modifications affecting the lubrication equipment).

[0070] If the detection interval is too long when the corresponding data is retrieved next time, the lubrication equipment can be re-detected.

[0071] This disclosure proposes a testing method for wind turbine generator sets. Figure 3 This is a flowchart illustrating a method for testing wind turbine generator sets according to an embodiment of the present disclosure. Figure 2 . Reference Figure 3 The testing method for the wind turbine generator set includes the following steps:

[0072] In step S301, in response to the fact that the current test item to be tested of the wind turbine generator set is associated with the lubrication equipment, a request is sent to the server to obtain the test information of the previous test of the lubrication equipment.

[0073] As an example, taking the server as the host computer, the control mechanism of the lubrication equipment by the controller is briefly explained. After the host computer initiates the detection of the wind turbine generator set, the controller (PLC) begins to execute the automatic detection process of the wind turbine generator set. When the detection of the lubrication equipment begins, the PLC automatically starts the lubrication equipment (lubrication pump) through the DO point and continues to run it for a sufficient period of time. After the lubrication equipment (lubrication pump) starts, the PLC detects the feedback signal of the lubrication pump. If the feedback signal of the lubrication pump changes between high and low levels, it is determined that the lubrication equipment is operating normally; if the feedback signal does not change (remaining at a high level or a low level), it is determined that the lubrication equipment is operating abnormally.

[0074] In step S301 of this disclosure, before starting the inspection of the lubrication equipment, a request is sent to the server to obtain the inspection information of the previous inspection of the lubrication equipment, so as to determine whether to inspect the lubrication equipment again based on the inspection information of the previous inspection.

[0075] According to embodiments of this disclosure, before the current test item for the wind turbine generator involves lubrication equipment, a startup message sent by the server can be received, indicating the start of the wind turbine generator test. This startup message is generated and sent by the server in response to updated test configuration information for the wind turbine generator. Based on the startup message, the test items for the wind turbine generator are then tested. According to this embodiment, each time the server restarts, it automatically removes the local test configuration information and waits for the user to input the latest test configuration information. That is, the user needs to resubmit the test configuration information before the wind turbine generator test process can begin. This ensures that the test configuration information for the wind turbine generator is the correct and required information each time a test is performed, avoiding subsequent errors due to incorrect test configuration information.

[0076] As an example, taking the server as the host computer, each time the host computer restarts, it can automatically remove the local detection configuration information. Then, the user fills in the latest detection configuration information and submits it. Only then is the start information for instructing the controller to start detecting the wind turbine generator set sent to the controller, thus initiating the detection process. If the latest detection configuration information filled in by the user is not detected, the start information for instructing the controller to start detecting the wind turbine generator set is not sent, that is, the detection process for the wind turbine generator set is not initiated. This ensures that the latest detection configuration information is used in each detection process, avoiding the use of incorrect information. For example, taking the detection time as an example, assuming the current time is 8:00 AM today, if you want to detect the wind turbine at 8:00 AM the next day, but you haven't removed the local detection configuration information and haven't entered the latest detection configuration information, then since there is no latest detection configuration information, when using the detection configuration information, it may use the original detection configuration information (i.e., the detection configuration information that was not removed above), that is, the detection of the wind turbine will start from the time in the original detection configuration information. Another possibility is that the local detection configuration information has been removed, but no latest detection configuration information has been entered. In this case, since there is neither the latest detection configuration information nor the original detection configuration information, it is very likely that when the host computer detects the current time, it is 8:00 AM today, and the wind turbine will be detected at 8:00 AM today, not at 8:00 AM the next day.

[0077] In step S302, the detection results of the previous detection of the lubrication equipment sent by the server are received.

[0078] It should be noted that the server can also determine whether the lubrication equipment is operating normally or abnormally based on the detection results. If the lubrication equipment is determined to be operating normally, the server can directly send a "detected flag" to the controller, and the controller will not perform another detection on the lubrication equipment. If the lubrication equipment is determined to be operating abnormally, the server can notify the controller to perform another detection on the lubrication equipment.

[0079] As an example, still using the server as the host computer, when the controller of the wind turbine receives a request to obtain the detection information of the previous detection of the lubrication equipment of the wind turbine, the host computer reads the information in memory. If the unit number, the time of the previous detection of the lubrication equipment in memory are consistent with the information currently submitted by the host computer, and the detection result in memory shows that the lubrication equipment is operating normally, and the number of process detections in memory is greater than 1, then the host computer sends a "detected flag" to the controller. At this time, the lubrication equipment will not be detected again, in order to reduce the running time of the lubricating oil pump and reduce the lubrication and grease filling time. If one of the above conditions is not met, the server can notify the controller to detect the lubrication equipment again.

[0080] In step S303, in response to the detection result indicating that the lubrication equipment is malfunctioning, the lubrication equipment is detected again, and after the detection of the lubrication equipment is completed, other detection items of the wind turbine generator set are detected.

[0081] In step S304, in response to the test result indicating that the lubrication equipment is operating normally, other test items of the wind turbine generator set are directly tested.

[0082] Specifically, after the controller receives the test results of the previous test of the lubrication equipment, if the previous test results indicate that the lubrication equipment is operating normally, the lubrication pump can be skipped directly without starting the lubrication pump. The process will determine that the lubrication equipment has passed the test and continue to the next test item. If the previous test results indicate that the lubrication equipment is operating abnormally, the controller will restart the lubrication pump through the digital output (DO) point to judge and test the feedback signal. Only after the test is completed can the other test items of the wind turbine generator be tested.

[0083] According to embodiments of this disclosure, after sending a request to the server for obtaining detection information from previous tests of the lubrication equipment, the system receives the detection duration of the previous tests of the lubrication equipment from the server. In response to a detection result indicating that the lubrication equipment is operating normally but the detection duration is within an abnormal range, the lubrication equipment is tested again. After the lubrication equipment test is completed, other detection items of the wind turbine generator are tested. In response to a detection result indicating that the lubrication equipment is operating normally and the detection duration is within a normal range, other detection items of the wind turbine generator are directly tested. According to this embodiment, the detection duration and detection result can be combined to determine whether to test the lubrication equipment again. This avoids the erroneous decision not to test the lubrication equipment again when the detection result indicates that the lubrication equipment is operating normally but the detection process is incorrect.

[0084] As an example, if the previous test results indicate that the lubrication equipment is operating normally, but the duration of the previous test was too short, such as the running time of the lubrication pump being too short, then the lubrication equipment also needs to be tested again. That is, the controller restarts the lubrication pump again through the DO point output to judge and test the feedback signal. Only after the test is completed can other test items of the wind turbine be tested to ensure the correctness of the test and the quality of the product leaving the factory.

[0085] According to embodiments of this disclosure, after sending a request to the server for obtaining detection information of previous detections of the lubrication equipment, the system receives the previous detection time of the lubrication equipment sent by the server; in response to the previous detection time, the lubrication equipment is detected again, and after the detection of the lubrication equipment is completed, other detection items of the wind turbine generator are detected. According to this embodiment, when the previous detection time is inconsistent with the current time, the previous detection time can be sent to the controller so that the controller can directly determine to re-detect the lubrication equipment based on the previous detection time.

[0086] As an example, taking the detection data as the number of detections, the predetermined threshold as 1, and the two times as the same date, when the queried detection information indicates that the number of detections of the lubrication equipment is greater than 1, and the time of the previous detection of the lubrication equipment is not on the same date as the current time, the previous detection time of the lubrication equipment is obtained and sent to the controller. The controller directly performs another detection on the lubrication equipment based on the previous detection time. That is, the controller restarts the lubrication pump again through the DO point output, judges and detects the feedback signal. Only after the detection is completed can other detection items of the wind turbine generator be detected to ensure the correctness of the detection and the quality of the product leaving the factory.

[0087] According to embodiments of this disclosure, after the lubrication equipment's detection is completed, the current detection result and / or current detection duration of the lubrication equipment can be sent to the server, so that the server can use the current detection result and / or current detection duration to update the previous detection result and / or detection duration of the lubrication equipment. According to this embodiment, upon receiving the current detection result and detection duration, the original detection result and detection duration in memory can be updated, facilitating subsequent detections to read the latest information.

[0088] Specifically, once the controller completes a re-inspection of the lubrication equipment, it can transmit the current inspection results and inspection duration to the server. The server stores this new data, which can be used to overwrite the original memory location storing this type of data, thus updating the data. Additionally, the inspection time can be updated simultaneously for status reading and judgment during the next inspection. It should be noted that if the controller does not re-inspect the lubrication equipment, it will not transmit any information to the server. That is, if the server does not receive any feedback, it will not update any information, such as the inspection time. Therefore, when reading the corresponding data again, if the inspection interval is too long, the lubrication equipment can be re-inspected.

[0089] As an example, taking the server as the host computer, after the controller detects the operating status of the lubrication pumps (including gearbox lubrication pumps, yaw lubrication pumps, and pitch lubrication pumps), it can transmit the detection completion flag and the detection result (pass or fail) to the host computer. The host computer stores the received detection completion flag, detection result, and information such as the wind turbine generator set number, detection time, number of detections, detection personnel, and detection duration. The storage method can be as shown in Table 2.

[0090] Table 2 Storage Method

[0091]

[0092]

[0093] The data can be stored in txt, data, excel or database formats, and this disclosure does not limit the format.

[0094] In Table 2 above, "serial number" is the wind turbine generator set number, used to determine whether it is the same wind turbine generator set as the one subsequently tested; "data_n" is the number of times the lubrication equipment has been tested, used to determine whether the time is consistent with the time of subsequent tests (if the time difference is small, it can be set to the same date, or a difference of less than 4 hours or 2 hours, etc.); "device_n" is the lubrication equipment testing enable, facilitating the activation and deactivation of the functions disclosed herein; "check_times" and "times_n" are used to determine whether process testing has been performed, where "check_times" is the total number of tests performed on the wind turbine generator set, and "times_n" is the number of tests performed on the wind turbine generator set. s_n represents the number of times the lubrication equipment has been tested. Both can be used together or separately, and this disclosure does not limit their use. check_status_n represents the test result of the lubrication equipment, used to analyze whether it is necessary to start the lubrication pump for testing in the future. period_n represents the testing duration of the lubrication equipment, used to help determine whether the running time of the last operation of the lubrication pump (i.e., the testing duration) is within the normal range. If it is within the abnormal range (e.g., the start time is too short), then even if the value of check_status_n is 1, the lubrication pump needs to be restarted for testing to ensure the correctness of the test and the quality of the product leaving the factory.

[0095] As an example, taking the data in Table 2 above, if the stored unit number (serial number) is the same as the unit number newly submitted by the host computer, the total number of checks (check_times) is greater than 1, the check time (data_n, using the actual lubrication equipment) is the same as the time newly submitted by the host computer, and the corresponding lubrication equipment's enable signal (i.e., explore_n in Table 2) is 1, then the host computer sends the previously detected check_status_n to the controller (PLC). After the PLC receives the detection result, if the value of check_status_n is 1 and the value of times_n is 1, it means that the lubrication equipment has been detected before and the detection result is that the lubrication equipment is operating normally. In this case, the lubrication pump will not be restarted and the process is judged as passing the detection. If the value of check_status_n is 0 or the value of times_n is 0, it means that the lubrication equipment has not been detected before or the detection result is that the lubrication equipment is operating abnormally. In this case, the PLC starts the lubrication pump through the DO point output to judge and detect the feedback signal. After the test is completed, the current test results and other information are transmitted to the host computer again, and the host computer stores the data for the status to be read and judged in the next test.

[0096] It should be noted that the above process logic can also be implemented in other ways, and this disclosure does not limit this approach.

[0097] The following is combined Figure 4 This disclosure will be explained from the perspective of the interaction between the host computer and the controller. Figure 4 This is a schematic diagram illustrating the interaction detection process between the controller and the host computer in an embodiment of this disclosure, as shown below. Figure 4 As shown, the interaction detection process is as follows:

[0098] 1) After the host computer starts, it can automatically clear the local detection configuration information. Then, the user fills in the latest detection configuration information and submits it to notify the controller to enter the detection preparation state. Only then will the host computer send the start information to the controller (such as PLC) to indicate that the detection of the wind turbine generator set has started. The controller starts the detection process, that is, the detection process begins to be executed. Otherwise, the host computer will not send the start information to the controller to indicate that the detection of the wind turbine generator set has started, that is, the detection process of the wind turbine generator set will not be started (the detection process here refers to the automated detection process of all detection items of the wind turbine generator set).

[0099] 2) When the detection process sequentially checks the above-mentioned items, after detecting a lubrication device (which can be determined based on the specified process number), the controller notifies the host computer. At this time, the host computer can read the locally stored information and compare it with the detection time and other information of the lubrication device in the newly submitted detection configuration information. If the information matches, the locally stored detection result of the lubrication device is sent to the PLC. It should be noted that if it has never been detected, the default detection result can be 0 (i.e., not detected). If the detection process has been executed before and detection results have been written, the information read is the previously stored detection result.

[0100] 3) After receiving the detection result, the PLC executes different detection functions depending on the result. Specifically, if the detection result status is 1, the lubrication pump is not started for detection, and the process is judged as passing the detection; if the detection result status is 0, the lubrication pump is started for detection.

[0101] 4) After the test is completed, the PLC transmits the new test result to the host computer, which then writes the new test result to the storage location. Optionally, if no test is performed this time, there is no need to re-store the data, that is, no write operation is required.

[0102] 5) After the lubrication equipment is inspected, the inspection sequence number is incremented by 1, and the next inspection item is started, until all inspection items are completed and all inspections are passed.

[0103] In summary, this disclosure is of great significance in preventing over-lubrication of rotating parts of wind turbines, ensuring sufficient lubricating grease during field operation, extending the service life of lubricating grease, ensuring safe operation of wind turbine units, reducing the probability of wind turbine unit downtime due to low oil level, and improving the service life of wind turbines.
