Description

Technical Field

[0001] This disclosure relates to the field of data processing, and more specifically, to a method, system, and storage medium for power plant equipment maintenance. Background Technology

[0002] Wear, aging, and performance degradation of thermal power equipment (such as boiler feed pumps, turbine bearings, induced draft fans, and transformers) are strongly correlated with "cumulative operating time" (for example, the design life of a certain type of feed pump seal is 10,000 hours, and the failure cycle of a certain motor bearing grease is 8,000 hours). However, current life-cycle management of thermal power plant equipment suffers from problems such as heavy reliance on manual labor, neglect of individual equipment health differences, and a single maintenance benchmark. This easily leads to problems of "not repairing what should be repaired and repairing what shouldn't be repaired," which is detrimental to improving the accuracy of equipment maintenance. It also easily leads to the accumulation of failure risks because maintenance is not triggered in time when the equipment has reached the condition requiring maintenance (such as excessive wear and performance degradation). Furthermore, it is easy to over-maintain equipment before it has reached the maintenance condition, resulting in waste of resources. Summary of the Invention

[0023] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

They are used together with the following detailed description to explain the present disclosure, but do not constitute a limitation thereof. In the drawings: Figure 1 This is a flowchart illustrating an exemplary embodiment of a power plant equipment maintenance method disclosed herein; Figure 2 It is based on Figure 1 The illustrated embodiment presents a flowchart of a power plant equipment maintenance method; Figure 3 It is based on Figure 1The illustrated embodiment shows a flowchart of another power plant equipment maintenance method; Figure 4 This is a block diagram of a power plant equipment maintenance system provided in an exemplary embodiment of this disclosure; Figure 5 This is a block diagram illustrating an electronic device according to an exemplary embodiment; Figure 6 This is a block diagram illustrating another electronic device according to an exemplary embodiment. Detailed Implementation

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0027] Before detailing the technical solution of this disclosure, the application scenarios of this disclosure are explained below. This disclosure applies to the maintenance process of power equipment, including power equipment in thermal power plants, wind power generation equipment, and nuclear power equipment. Taking the maintenance of power equipment in thermal power plants as an example, current thermal power units generally adopt a "one in operation, one standby" or "two in operation, one standby" mode, with equipment such as feedwater pumps, induced draft fans, and coal mills being rotated 2-3 times daily. Existing systems only use the DCS "start / stop signal" or "current > 5%" as the timing switch. Once the standby equipment signal is ON, the time is fully accumulated, while the equipment actually under load is stopped and its time is accumulated due to the switching. At the end of the month, the time is manually estimated and filled back according to the "operation ratio," and the calculation results of different personnel for the same equipment have an error of ≥ 20%. The more frequent the peak shaving, the greater the deviation. In extreme cases, the accumulated time can differ by a factor of 10, which makes it particularly easy to cause the problem of "not repairing what should be repaired and repairing what should not be repaired."

[0028] To address the aforementioned technical issues, this disclosure provides a power plant equipment maintenance method, system, and storage medium. This method can generate maintenance prompts based on the equipment wear duration, a preset wear duration threshold, and wear adjustment monitoring parameters. This effectively improves the accuracy of equipment maintenance, avoids the accumulation of fault risks caused by equipment reaching a state requiring maintenance but failing to trigger repairs in a timely manner, and effectively reduces resource waste caused by over-maintenance of equipment.

[0029] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0030] Figure 1This is a flowchart illustrating an exemplary embodiment of a power plant equipment maintenance method, such as... Figure 1 As shown, the method may include: Step 101: Obtain the status data of the target device under load, including the current power load and operation image information.

[0031] The operational image information can be an image of a preset part of the equipment, such as an image of the bearing. When the equipment is an induced draft fan, the operational image information can include images of the fan's operating parts and images of the flue gas conveying parts.

[0032] Step 102: Determine the equipment loss duration and the loss adjustment monitoring parameters of the target equipment based on the power load and the operation image information. The loss adjustment monitoring parameters include at least a first operating duration greater than a first load threshold and a second operating duration less than a second load threshold, wherein the first load threshold is greater than the second load threshold.

[0033] In this step, the current operating status of the target device can be identified from the operating image information. The current operating status is either a normal operating status or an abnormal operating status. If the current operating status is a normal operating status, the third operating time when the power load is greater than the third load threshold, the first operating time when the power load is greater than the first load threshold, the second operating time when the power load is less than the second load threshold, and the third load threshold being less than the second load threshold are accumulated. The third operating time is used as the device loss duration, and the first operating time and the second operating time are used as the loss adjustment monitoring parameters.

[0034] For example, when the operational image information includes images of the fan operating section and the flue gas conveying section, if it is determined from the operational image information that the fan is operating and flue gas is being conveyed, the current operating state of the target equipment is determined to be normal; and if the current operating state is determined to be normal operating state, the equipment loss duration, the first operating duration and the second operating duration are determined based on the power load.

[0035] Step 103: Obtain the preset loss duration threshold for each maintenance level among multiple maintenance levels.

[0036] These multiple maintenance levels can include routine maintenance, overhaul maintenance, and replacement maintenance. The preset wear time threshold for routine maintenance is less than the preset wear time threshold for overhaul maintenance, and the preset wear time threshold for overhaul maintenance is less than the preset wear time threshold for replacement maintenance.

[0037] Step 104: Generate maintenance prompt information based on the equipment wear time, the preset wear time threshold, and the wear adjustment monitoring parameters.

[0038] One possible implementation method in this step is as follows: Figure 2 As shown, Figure 2 It is based on Figure 1 The illustrated embodiment presents a flowchart of a power plant equipment maintenance method, including: S11, Generate a threshold adjustment coefficient based on the loss adjustment monitoring parameters.

[0039] Specifically, if the first runtime is determined to be greater than a first runtime threshold, a first coefficient may be used as the threshold adjustment coefficient, wherein the first coefficient is greater than 1; if the second runtime is determined to be greater than a second runtime threshold, a second coefficient may be used as the threshold adjustment coefficient, wherein the second coefficient is less than 1.

[0040] For example, although standby equipment (such as a standby water pump) has a short operating time, prolonged inactivity may lead to problems such as bearing corrosion and component jamming. Therefore, the system adds an additional "inactivity time threshold." For instance, if standby equipment is inactive for more than 30 days (i.e., the second operating time), even if this second operating time does not reach the preset wear time threshold corresponding to maintenance, a "turning gear and lubrication oil check" reminder should still be triggered to compensate for the limitations of pure "operating time" statistics. To trigger the "turning gear and lubrication oil check" reminder when the operating time does not reach the preset wear time threshold corresponding to maintenance, the preset wear time threshold can be reduced by setting a coefficient less than 1 (i.e., a second coefficient). The target wear time threshold is then generated based on the preset wear time threshold and the threshold adjustment coefficient.

[0041] S12, Generate a target loss time threshold based on the preset loss time threshold and the threshold adjustment coefficient.

[0042] Specifically, for each maintenance level, the product of the threshold adjustment coefficient and the preset loss duration threshold can be used as the target loss duration threshold.

[0043] S13, generate the maintenance prompt information based on the equipment wear time and the target wear time threshold.

[0044] Through the above steps S11 to S13, a target loss time threshold can be generated based on the preset loss time threshold and the threshold adjustment coefficient, and the maintenance prompt information can be generated based on the equipment loss time and the target loss time threshold, thereby effectively improving the accuracy of equipment maintenance.

[0045] Another possible implementation of step 104 can be as follows: Figure 3As shown, Figure 3 It is based on Figure 1 The flowchart of another power plant equipment maintenance method shown in the embodiment includes: S21, Generate a loss duration adjustment coefficient based on the loss adjustment monitoring parameters.

[0046] In this step, if the first runtime is determined to be greater than the third runtime threshold, the third coefficient can be used as the loss duration adjustment coefficient corresponding to the first runtime, and the third coefficient is greater than 1; if the second runtime is determined to be greater than the fourth runtime threshold, the fourth coefficient can be used as the loss duration adjustment coefficient corresponding to the second runtime, and the fourth coefficient is less than 1.

[0047] For example, the high-pressure cylinder of a certain steam turbine is designed to have a service life of 120,000 hours. If it operates under the condition of "10% over the rated load" for a long time, the threshold adjustment coefficient k=1.2 is set. That is, if it actually runs for 10 hours, the cumulative loss time is calculated as 12 hours (10×1.2) to trigger the maintenance reminder in advance.

[0048] S22, generate an adjusted standby time based on the device loss time and the loss time adjustment coefficient.

[0049] This step determines the remaining runtime of the equipment's wear time, excluding the first runtime and the second runtime; the product of the first runtime and the third coefficient is taken as the first part of the wear time; the product of the second runtime and the fourth coefficient is taken as the second part of the wear time; and the sum of the remaining runtime, the first part of the wear time, and the second part of the wear time is taken as the standby wear time.

[0050] S23, generate the maintenance prompt information based on the standby time and the preset time threshold.

[0051] Specifically, if the difference between the standby wear time and the preset wear time threshold is less than or equal to the preset prompt threshold, a multi-dimensional prompt can be issued every preset time period. For example, when the standby wear time of the target device reaches the preset wear time threshold corresponding to maintenance, a maintenance prompt message is issued; when the standby wear time of the target device reaches the preset wear time threshold corresponding to inspection and maintenance, an inspection prompt message is issued; and when the standby wear time of the target device reaches the preset wear time threshold corresponding to replacement and maintenance, a replacement prompt message is issued.

[0052] It should be noted that multi-dimensional prompts can include system pop-up prompts, i.e., reminder windows that pop up on the homepage of the EAM system or the thermal power intelligent operation and maintenance platform, directly reaching the operation and maintenance personnel logged into the system; SMS notification prompts, i.e., sending SMS reminders to the mobile phones of operation and maintenance engineers and team leaders to ensure that personnel can receive information even when they are not at their computers; and email notification prompts, i.e., sending detailed reminder emails to relevant personnel's email addresses, including a complete description of maintenance requirements and attachments (such as equipment ledgers and maintenance process documents). The content of the maintenance prompt information can include key information such as "equipment name, current running time, maintenance actions to be performed, and deadline," to facilitate operation and maintenance personnel to quickly understand the requirements and arrange work. For example, it could be, "#2 induced draft fan has been running for 7800 hours, and there are only 200 hours left until the 'bearing inspection' threshold of 8000 hours. Please arrange a schedule."

[0053] It should be noted that after step 104, the method may further include: associating the prompt information with the equipment ledger and generating a corresponding maintenance work order, and displaying the maintenance work order through a preset maintenance window to facilitate timely maintenance.

[0054] It may also include automatically resetting the equipment wear time, first running time and second running time of the device if a "maintenance completion confirmation" signal is received after the maintenance personnel enter the maintenance record and submit it for acceptance, when information such as "actual maintenance time, replacement of spare parts, and inspection results" are obtained.

[0055] The above technical solutions can effectively improve the accuracy of equipment maintenance, avoid the accumulation of failure risks caused by equipment reaching the maintenance required state but not being repaired in time, and effectively reduce the waste of resources caused by over-maintenance of equipment.
