Description

Technical Field

[0001] The present invention relates to the technical field of rotor image acquisition, and in particular to a rotor image acquisition method, device, electronic equipment and storage medium. Background Art

[0002] The rotor of a hydro-turbine generator is prone to abnormalities due to factors such as high speed and variable operating conditions. Therefore, it is necessary to monitor or inspect the rotor. Inspection by turning the rotor in a stopped state or using an endoscope is inefficient and causes a waste of manpower.

[0003] With the development of artificial intelligence technology, some power stations are currently trying to use cameras, infrared thermal imagers, industrial cameras and other equipment to collect images of rotors and combine artificial intelligence image recognition algorithms to judge the acquired images. The working mode of current application technology solutions is mostly to use equipment to continuously monitor or regularly inspect the rotor. Continuous monitoring will generate a large amount of useless non-abnormal data, which will put great pressure on the storage and operation resources of the host computer system.

[0004] Regular inspection can reduce the great pressure on the storage and operation resources of the host computer system. Regular inspection can be understood as periodically collecting images of the rotor. Regular inspection can reduce the pressure on the storage and operation resources of the host computer system.

[0005] Since there is a time interval between two adjacent image acquisitions during the scheduled inspection, and the exposure of rotor defects is not a continuous state, there is a situation where the moment when the rotor defects are exposed is in the gap between two adjacent image acquisitions. As a result, the monitoring results cannot reflect the actual situation of the hydro-turbine generator, and there are safety hazards in the operation of the hydro-turbine generator. Summary of the invention

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0035] In the description of the specification, the terms "one embodiment", "some embodiments", "exemplarily", "example", or "some examples" are intended to indicate that a specific feature, structure, material, or characteristic associated with the embodiment or example is included in at least one embodiment or example of the present application. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials, or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0036] In the related art, defects such as open turns at the pole ends of the rotor of the hydro-turbine generator, loose connection of the pole lead wires and the rotor lead wires, deformation of the inter-pole connecting wires and the pole lead wires, and lead wire insulation burnout usually occur when the rotor is in an overspeed state. Some defects are even exposed in the rotor overspeed state, but hidden when the rotor is out of the overspeed state. For example, cracks on the rotor are exposed in the rotor overspeed state, but hidden when the rotor is out of the overspeed state. Rotor overspeed usually occurs in an instant or lasts for a short time. There is a time interval between two adjacent image acquisitions during the scheduled inspection, which will miss the defects that are exposed instantly or briefly in the rotor overspeed state. Therefore, these defects that are exposed instantly or briefly in the rotor overspeed state and represent rotor abnormalities are difficult to be captured by the image acquisition device. There is a situation where the captured rotor image appears normal, but the actual rotor is abnormal. The monitoring results are inaccurate, and there are safety hazards in the continuous operation of the hydro-turbine generator.

[0037] Based on this, the embodiments of the present application provide a rotor image acquisition method, a rotor image acquisition device, an electronic device and a storage medium, which are used to improve the problem in the related technology that when monitoring defects of a hydro-turbine generator rotor, the monitoring results are inaccurate, and there are safety hazards in the continuous operation of the hydro-turbine generator.

[0038] Reference Figure 1The embodiment of the present application provides a rotor image acquisition method, which can be implemented by a rotor image acquisition device, a control device and a speed sensor. Specifically, the control device is connected to the speed sensor and the image acquisition device by signal, and the control device can obtain the working speed of the turbine unit through the speed sensor to determine the working state of the turbine unit, and control the image acquisition device to acquire the image of the rotor or stop acquiring the image of the rotor according to the working state of the turbine unit.

[0039] The rotation speed sensor and the control device may be integrated together, or both may be integrated with the image acquisition device, or both may be separately arranged with the image acquisition device.

[0040] In some embodiments, the method comprises the steps of:

[0041] S101: In response to a water turbine unit being in an overspeed state, controlling an image acquisition device to acquire an image of a rotor.

[0042] Among them, the turbine unit being in an overspeed state means that the speed of the rotor in the turbine generator exceeds the maximum speed allowed by the design. The maximum speed can be the rated speed, or a speed that exceeds the rated speed by a certain proportion or value.

[0043] In some embodiments, S101 may include: the control device controls the image acquisition device to acquire an image of the rotor in response to the turbine unit processing overspeed state. The control device may be built into the image acquisition device, in which case the control device may be a processor with computing capabilities. Alternatively, the control device may be provided separately from the image acquisition device as a separate device and connected to the image acquisition device by signal. In this case, the control device may include a processor with computing capabilities.

[0044] Defects such as open turns at the pole ends, loosening of the pole lead wires and rotor lead wires, abnormal deformation of the inter-pole connection wires and pole lead wires, and lead wire insulation burnout often occur when the turbine unit is in an overspeed state. Therefore, it is easier to capture images of defects that represent rotor abnormalities when the turbine unit is in an overspeed state.

[0045] The image acquisition device provided in this embodiment may include but is not limited to a video camera, an infrared thermal imager, an industrial camera, etc.

[0046] In this embodiment, in response to the turbine unit being in an overspeed state, the image acquisition device is controlled to acquire an image of the rotor, thereby realizing image acquisition of the rotor in the overspeed state, making it easier to acquire images of defects representing abnormal rotors, thereby improving the accuracy of monitoring results and thus improving the operating safety of the hydro-generator.

[0047] In some embodiments, in response to the turbine unit being in an overspeed state, the process of controlling the image acquisition device to acquire an image of the rotor may specifically include:

[0048] Continuously monitor the working status of the turbine unit. At the same time, in order to reduce the storage and computing pressure brought by the working status data of the turbine unit, the monitoring frequency of the working status of the turbine unit can be reduced to a certain extent;

[0049] And when it is first determined that the turbine unit is in an overspeed state, the image acquisition device is controlled to start acquiring images of the rotor to improve the timeliness of image acquisition.

[0050] The process of monitoring the working state of the turbine unit can specifically include detecting the working speed of the rotor and comparing the working speed with the rated speed. If the working speed exceeds the rated speed, the turbine unit is in an overspeed state. The detection of the working speed of the rotor can be achieved by a speed sensor, and the comparison of the working speed with the rated speed can be completed by a control device. The control device can obtain the working speed of the turbine unit through the speed sensor and compare it with the rated speed to monitor the working state of the turbine unit. Then, when it is first determined that the turbine unit is in an overspeed state, the image acquisition device is controlled to start acquiring images of the rotor.

[0051] In some embodiments, when it is determined that the operating speed of the water turbine unit is ≥110% Nr, it is determined that the water turbine unit is in an overspeed state, wherein Nr represents the rated speed of the water turbine unit.

[0052] In specific applications, the rotor's operating speed runs relatively smoothly within the range of Nr to 110% Nr, which belongs to the stable speed fluctuation range. The possibility of abnormality of the turbine unit within this operating speed range is low. Therefore, when the operating speed of the turbine unit is ≥ 110% Nr, controlling the image acquisition device to acquire the image of the rotor can greatly reduce the pressure caused by the image data on operating resources and storage.

[0053] The operating speed of the turbine unit refers to the current operating speed of the turbine unit. The process of determining that the speed of the turbine unit is ≥ 110% Nr is specifically to compare the current operating speed of the turbine unit with 110% Nr. If the current operating speed of the turbine unit is greater than or equal to 110% Nr, it indicates that the turbine unit is in an overspeed state.

[0054] According to the operation requirements, the rated speed Nr of different turbines may be different. In some embodiments, for a 50 Hz power system, Nr may be set to 1500 r / min, 1000 r / min, 750 r / min, etc. In some embodiments, for a 60 Hz power system, Nr may be set to one of 1800 r / min, 1200 r / min, 900 r / min, etc.

[0055] In some embodiments, the rotor image acquisition method may further include the following steps:

[0056] In response to the turbine unit being out of the overspeed state, the image acquisition device is controlled to stop acquiring rotor images and upload the acquired rotor images.

[0057] Specifically, the current operating speed of the rotor may be detected and compared with 110% Nr. If the current operating speed of the rotor is less than 110% Nr, it indicates that the turbine unit is out of the overspeed state.

[0058] Optionally, the host computer controls the image acquisition device to stop image acquisition, and obtains the rotor image that has been acquired by the image acquisition device.

[0059] The above embodiment provides a method for collecting images of the overspeed state of a water turbine unit. It should be understood that the working state of a water turbine unit includes, in addition to the overspeed state, the startup acceleration state, the shutdown deceleration state, and the stable operation state.

[0060] Among them, the startup acceleration state refers to the stage in which the speed of the turbine unit gradually increases from 0 to the rated speed Nr after the turbine unit receives the startup signal. In the startup acceleration state, the speed of the turbine unit is getting faster and faster.

[0061] The shutdown deceleration state refers to the stage where the speed of the turbine unit gradually decreases to 0 after shutdown until the turbine unit stops running. In the shutdown deceleration state, the speed of the turbine unit becomes slower and slower.

[0062] The stable operation state refers to the stage in which the rotation speed of the turbine unit is stable at the rated rotation speed Nr or stable near the rated rotation speed Nr.

[0063] In some embodiments, the process of acquiring the image of the rotor in the overspeed state mentioned in the above embodiment may specifically include:

[0064] It is monitored that the turbine unit switches from a stable operation state to an overspeed state, and control starts to collect images.

[0065] It should be understood that the rotor of the turbine unit may also be abnormal in addition to the overspeed state, startup acceleration state, shutdown deceleration state and stable operation state. In order to improve the image data sample, it is possible to consider periodically collecting the image of the rotor in at least one of the acceleration state, shutdown deceleration state and stable operation state.

[0066] In some embodiments, the rotor image acquisition method may further include the following steps:

[0067] In response to the turbine unit being in a startup acceleration state, the image acquisition device is controlled to periodically acquire images of the rotor.

[0068] Furthermore, in response to a start-up signal of the water turbine unit, the image acquisition device is controlled to start periodically acquiring images of the rotor, so that the image of the rotor at the moment of starting the water turbine unit can be acquired.

[0069] The start-up signal is a signal that triggers the start-up of the hydro-turbine generator. In response to the start-up signal of the hydro-turbine unit, the image acquisition device is controlled to start periodically acquiring images of the rotor, which helps to ensure the comprehensiveness of monitoring the operating status of the hydro-turbine unit. Specifically, it can be determined whether the hydro-turbine generator has received the start-up signal based on the current, power and other information obtained by the state monitoring system, the equipment operation supervision system or the hydro-turbine generator management system.

[0070] In some embodiments, the rotor image acquisition method may further include the following steps:

[0071] In response to the turbine unit being in a shutdown and deceleration state, the image acquisition device is controlled to periodically acquire images of the rotor.

[0072] Specifically, when it is monitored that the turbine unit switches from a stable operation state to a shutdown and deceleration state, the image acquisition device is controlled to start acquiring images of the rotor.

[0073] After receiving the shutdown signal, the turbine unit will enter the shutdown deceleration stage. In some embodiments, the rotor image acquisition method may further include the following steps:

[0074] In response to the shutdown signal of the water turbine unit, the image acquisition device is controlled to start periodically acquiring images of the rotor, so that the image of the rotor at the moment when the water turbine unit receives the shutdown signal can be acquired.

[0075] The shutdown signal is a signal that triggers the shutdown of the hydro-generator. Specifically, the shutdown of the hydro-generator can be determined based on information such as current and power obtained by a state monitoring system, an equipment operation supervision system, or a hydro-generator management system.

[0076] Timely uploading of the acquired rotor images to the host computer can improve the timeliness of uploading the image data.

[0077] In some embodiments, the rotor image acquisition method may further include the following steps:

[0078] In response to the turbine unit being in a stable operating state, the image acquisition device is controlled to stop acquiring images of the rotor and upload the acquired rotor images, thereby improving the timeliness of image data uploading and reducing the risk of image data loss.

[0079] The specific time for stopping data collection may be when it is first detected that the turbine unit is in a stable operating state.

[0080] Specifically, when the turbine unit is monitored to switch from the startup acceleration state to the stable operation state, the image acquisition device is controlled to stop acquiring images. Alternatively, when the turbine unit is monitored to switch from the overspeed state to the stable operation state, the image acquisition device is controlled to stop acquiring images.

[0081] Specifically, it can be determined that the turbine unit is in a stable operating state based on 95% Nr≤current rotor speed<110% Nr and current rotor speed≥90% Un, wherein Un is the rated voltage of the turbine unit.

[0082] In some embodiments, the rotor image acquisition method may further include the following steps:

[0083] In response to the turbine unit entering a shutdown state, the image acquisition device is controlled to stop acquiring images of the rotor, and the acquired rotor images are uploaded.

[0084] The specific time for stopping data collection may be when it is first detected that the water turbine unit is in a shutdown state.

[0085] Specifically, when the turbine unit is monitored to switch from the shutdown deceleration state to the shutdown state, the image acquisition is controlled to stop. It can be understood that after the shutdown signal, the turbine unit enters the shutdown deceleration state until the rotor stops, that is, the turbine unit enters the shutdown state, and after the turbine unit is shut down, the image acquisition of the rotor stops. The host computer sends a command to control the image acquisition device to stop image acquisition.

[0086] Reference Figure 2 , the present application embodiment provides a specific implementation flow chart of a rotor image acquisition method, including the following steps:

[0087] Step 1: Monitor the on / off signal of the turbine unit and monitor the working status of the turbine unit.

[0088] Step 2: When the turbine unit is monitored to be in a startup acceleration state, the image acquisition device is controlled to start periodically acquiring rotor images starting from the first monitoring of the turbine unit startup signal;

[0089] Step 3: When the turbine unit is monitored to be in a stable operating state, the image acquisition device is controlled to stop acquiring rotor images and the acquired rotor images are uploaded.

[0090] Step 4: When the turbine unit is monitored to be in an overspeed state, the image acquisition device is controlled to continuously acquire images of the rotor.

[0091] Step 5: When the turbine unit is monitored to be out of the overspeed state, the image acquisition device is controlled to upload the acquired rotor image.

[0092] Step 6: When it is monitored that the turbine unit is in the shutdown and deceleration stage, the image acquisition device is controlled to periodically acquire images of the rotor starting from the first monitoring of the shutdown signal of the turbine unit.

[0093] Step 7: When the turbine unit is shut down and stops running, the image acquisition device is controlled to stop acquiring images of the rotor, and the acquired rotor images are uploaded to the host computer.

[0094] Reference Figure 3 The embodiment of the present application also provides a specific implementation flow chart of a rotor image acquisition method, including the following steps:

[0095] Step 1: Monitor the on / off signal of the turbine unit and monitor the working status of the turbine unit.

[0096] Step 2: When the turbine unit is monitored to be in a startup acceleration state, the image acquisition device is controlled to start periodically acquiring rotor images starting from the first monitoring of the turbine unit startup signal;

[0097] Step 3: When the turbine unit is monitored to be in a stable operating state, the image acquisition device is controlled to periodically acquire images of the rotor and the acquired rotor images are uploaded.

[0098] Step 4: When the turbine unit is monitored to be in an overspeed state, the image acquisition device is controlled to continuously acquire images of the rotor.

[0099] Step 5: When the turbine unit is monitored to be out of the overspeed state, the image acquisition device is controlled to upload the acquired rotor image.

[0100] Step 6: When it is monitored that the turbine unit is in the shutdown and deceleration stage, the image acquisition device is controlled to periodically acquire images of the rotor starting from the first monitoring of the shutdown signal of the turbine unit.

[0101] Step 7: When the turbine unit is shut down and stops running, the image acquisition device is controlled to acquire an image of the rotor, and the acquired rotor image is uploaded to the host computer.

[0102] Figure 3 and Figure 2 The difference between the specific implementation process of rotor image acquisition shown is that: Figure 3 In the process, when the rotor image is in a stable operating state, the image acquisition device uploads the acquired rotor image and periodically acquires the rotor image.

In some embodiments, the rotor image acquisition device 200 may further include an analysis module 202, which is used to obtain the current working speed of the turbine unit, and the analysis module 202 is used to analyze the working state of the turbine unit according to the current working speed of the turbine unit.
