Abstract
Description
Technical Field
[0001] The present application relates to the field of port operation and maintenance, and in particular to an intelligent operation and maintenance decision-making planning method and device based on port breakwater wind power. Background Art
[0002] Wind turbine operation and maintenance (O&M) is a critical component of offshore wind power, accounting for approximately 25% of the total construction cost. However, current research and application of wind turbine O&M, particularly intelligent O&M, remains relatively basic. Existing methods for wind turbine O&M on port breakwaters primarily monitor wind turbine operation through deployed sensors and diagnose operational failures based on this data. Once a failure is detected, a fault maintenance task is generated and appropriate maintenance resources are mobilized. This approach can, to a certain extent, reduce the duration of wind turbine failures and improve turbine power generation stability.
[0003] However, existing methods still have significant shortcomings. They primarily focus on identifying operational obstacles to wind turbines, failing to fully consider the potential impact of actual sea conditions and meteorological data on port breakwaters and wind turbine equipment. Furthermore, existing methods overlook the potential damage to the structural health of port breakwaters and wind turbine equipment caused by long-term seawater erosion. Consequently, existing methods are unable to cope with complex and changing sea and meteorological conditions, as well as structural damage, and are in urgent need of further improvement.

The calculation formula of the wave height limit coefficient αh is: , hx is the wave height and hy is the breakwater height.
[0077] Calculate the wind power equipment application risk coefficient XBa, the specific formula is:
[0078]
[0079] S103: When the breakwater defense risk coefficient exceeds a preset breakwater safety threshold or / and when the wind power equipment application risk coefficient exceeds a preset equipment safety threshold, generating a defense task;
[0080] Compare the calculated breakwater defense risk coefficient with the preset safety value. If the former is greater than the latter, it is determined that the breakwater defense risk exceeds the limit; similarly, compare the wind power equipment application risk coefficient with the preset safety value. If the former is greater than the latter, it is determined that the wind power equipment application risk exceeds the limit.
[0081] When the application risk of breakwater or wind power equipment exceeds the preset threshold and meets the conditions for generating defensive tasks

[0091] The calculated breakwater structure health loss coefficient and wind power equipment structure health loss coefficient are compared with the corresponding set upper limit values of the structure health loss coefficient. If the calculated value is greater than the upper limit value, the structure health loss exceeds the limit.

[0093] Calculate the wind power Pf during wind power conversion. The specific formula is:
[0094]
[0095] Among them, ρk, Ay, vf, and Cp are air density, impeller area, wind speed, and wind power conversion power coefficient respectively, Cp∈U0[b0,a0], U0[b0,a0] is the preset value interval of the wind power conversion power coefficient, a0 is the maximum value of the wind power conversion power coefficient, and b0 is the minimum value of the wind power conversion power coefficient.
[0096] Calculate the maximum power loss coefficient ζa during wind power conversion. The specific formula is:
[0097]
[0098] Among them, Pc is the generated power and Pfmin is the minimum wind power.
[0099] The obtained maximum power loss coefficient is compared with the preset power loss upper limit. If the former is greater than the latter, it is determined that the power loss of the wind turbine generator set exceeds the limit; otherwise, it is determined to be normal.
[0100] Compare the motor temperature and gearbox oil temperature with the preset optimal range of motor temperature and gearbox oil temperature. If the motor temperature and gearbox oil temperature are both in the corresponding optimal range, the operating temperature of the wind turbine is normal. Otherwise, the operating temperature of the wind turbine exceeds the limit.
[0101] If the power loss of the wind turbine exceeds the limit or the operating temperature exceeds the normal range, it is determined that there is a fault in the operation of the wind turbine, which meets the conditions for generating a repair task; conversely, if the power loss and operating temperature are normal, it is determined that there is no fault in the operation of the wind turbine.
[0102] S106. Generate a defense urgency coefficient and / or a repair urgency coefficient according to the defense task and / or the repair task;
[0103] When there are daily tasks and repair tasks, repair tasks are processed first. After the repair tasks are processed, daily tasks will continue to be processed. Repair tasks that appear at different times are sorted according to their order of priority. For multiple repair tasks at the same time, the priority is determined by calculating the processing priority coefficient XPi. The specific formula is as follows:
[0104]
[0105] Among them, nbi is the target processing resource type number of the i-th repair task, mbij is the target resource number of the j-th target processing resource of the i-th repair task, mxij is the total resource number of the j-th target processing resource of the i-th repair task, λxi is the repair urgency coefficient of the i-th repair task, and the repair tasks at the same moment are sorted from high to low according to the calculated processing priority coefficient.
[0106] Specifically, it should be noted that the specific calculation formula of the repair urgency coefficient λx is:
[0107]
[0108] Among them, Xse is the set upper limit of the wind turbine structure health loss coefficient, Xsr is the set upper limit of the breakwater structure health loss coefficient, ζe is the preset power loss upper limit, βtd and βty are the motor temperature over-limit coefficient and gearbox oil temperature over-limit coefficient respectively. The specific calculation formula is as follows:

If the reason for the judgment generation of the repair task is that the health loss of the breakwater structure exceeds the limit, then , the values of other calculation items are 0, and the other situations are consistent with this.
[0111] When processing daily, repair, and defense tasks, defense tasks should be processed first. After completing defense tasks, repair tasks should be processed, and finally daily tasks. For defense tasks that appear at different times, they should be sorted in order of priority. For multiple defense tasks at the same time, the processing priority coefficient XQi of each task needs to be calculated. The specific formula is:
[0112]
[0113] Where nci is the target processing resource type number of the i-th defensive task, mcij is the target resource number of the j-th target processing resource of the i-th defensive task, myij is the total resource number of the j-th target processing resource of the i-th defensive task, and λfi is the defense urgency coefficient of the i-th defensive task. The defensive tasks at the same moment are sorted from high to low according to the calculated processing priority coefficients.
[0114] Specifically, it should be noted that the specific calculation formula of the defense urgency coefficient λf is:
[0115]
[0116] Among them, XFe is the preset breakwater defense risk safety value, XBe is the preset wind power equipment application risk safety value, if the reason for the determination of the defensive task is that the breakwater defense risk exceeds the limit, then , the other calculation item value is 0. If the reason for the determination of the defensive task is that the risk of wind power equipment application exceeds the limit, then , the other calculation item value is 0.
[0117] S107 generates a processing priority coefficient based on the target resource quantity and processing time of the daily task;
[0118] When it is determined that the conditions for generating a defensive task or a repair task are met, a corresponding defensive task or a repair task is generated and the target processing resource type, target resource quantity, and target processing time of the task processing are analyzed.
[0119] Specifically, the steps for analyzing the resources and duration required for task processing are as follows:
[0120] After obtaining permission, search the Internet for historical processing records (defensive or repair) whose similarity to the generated task exceeds the preset standard;
[0121] Using each historical task processing record as a reference, the expected resource type, resource quantity, and expected processing time of the generated defensive or repair tasks are estimated;
[0122] Summarize the expected resource types, quantities, and durations, determine the target processing resource types, calculate the average (rounded up) of the quantities of each type of resource as the target resource quantity, calculate the average of the expected durations as the target processing duration, and mark these as the resources and duration required for initial processing of the task.
[0123] After completing a defensive or repair task, we adjust the initial estimated resources and duration based on the actual resources and duration required for the task, thereby determining the new target processing resource type, target resource quantity, and target processing duration.
[0124] What needs to be specifically explained in this application is that, for ease of understanding, a set of data is given for illustration: assuming that there are three reference historical task processing records, represented by F1, F2, and F3 respectively.
[0125] The expected resource types for processing the generated task estimated by F1 are A1, A2, and A3, the number of resources is A1=12, A2=15, and A3=18, and the expected processing time is T1=10 minutes.
[0126] The expected resource types for processing the generated task estimated by F2 are A1, A3, and A4, the resource quantities are A1=10, A3=12, and A4=8, and the expected processing time is T2=12 minutes.
[0127] The expected resource types for processing the generated task estimated by F3 are A2, A3, and A4, the resource quantities are A2=16, A3=10, and A4=12, and the expected processing time is T3=14 minutes.
[0128] After aggregation, the target processing resource types are A1, A2, A3, and A4. The target resource quantity for A1 is (12 + 10 + 0) / 3 = 7.33, which is rounded up to 8. The target resource quantity for A2 is (15 + 0 + 16) / 3 = 10.33, which is rounded up to 11. The target resource quantity for A3 is (18 + 12 + 10) / 3 = 13.33, which is rounded up to 14. The target resource quantity for A4 is (0 + 8 + 12) / 3 = 6.67, which is rounded up to 7. Therefore, the target resource quantities for A1 are 8, A2 are 11, A3 are 14, and A4 are 7. The average target processing time is calculated as (10 minutes + 12 minutes + 14 minutes) / 3 = 12 minutes.
[0129] Analyze the target processing resource type, target resource quantity and target processing time for daily wind power task processing at port breakwaters;
[0130] The routine tasks in this application specifically include daily inspections of wind turbines, offshore booster stations, wind towers, and submarine cables, as well as regular maintenance of mechanical, electrical, and infrastructure equipment.
[0131] What needs to be specifically explained in this application is that the processing resource and duration analysis steps for the daily tasks of port breakwater wind power are the same as the analysis steps for defensive or repair tasks.
[0132] S108, generating a task processing sequence based on the defense urgency coefficient, the repair urgency coefficient, and the processing priority coefficient;
[0133] S109: Execute the defensive tasks, repair tasks and daily tasks according to the task processing sequence.
[0134] Set the priority of task type. Defensive tasks have the highest priority, repair tasks have a medium priority, and daily tasks have the lowest priority.
[0135] When only daily tasks exist, sort them according to the order in which they appear. For multiple daily tasks at the same time, calculate the processing priority coefficient XRi of each daily task. The specific formula is:
[0136]
[0137] Among them, nai is the target processing resource type quantity of the i-th daily task, maij is the target resource quantity of the j-th target processing resource of the i-th daily task, mzij is the total resource quantity of the j-th target processing resource of the i-th daily task, Tci is the target processing time of the i-th daily task, and the daily tasks at the same time are sorted from high to low according to the calculated processing priority coefficient.
[0138] To facilitate understanding of the above formula, a set of examples are given for explanation:
[0139] Assume that there are three daily tasks F1, F2, and F3 at the same time:
[0140] Solving task F1 only requires resource A, the specific quantity is 2, and the target processing time is 10 minutes.
[0141] Solving task F2 requires resources B and C, with the corresponding resource quantities being 1 and 3, respectively, and the target processing time being 12 minutes.
[0142] Solving task F3 requires resources A, B, and C, with the corresponding resource quantities being 4, 3, and 1, respectively, and the target processing time being 18 minutes.
[0143] The total number of resources A, B, and C are 15, 20, and 25 respectively, so the processing priority coefficient of task F1 is
[0144]
[0145] The processing priority coefficient of task F2 is
[0146]
[0147] The processing priority coefficient of task F3 is
[0148]
[0149] The processing order is F3, F2, F1.
[0150] When faced with daily tasks and repair tasks, repair tasks should be processed first. After the repair tasks are completed, daily tasks can be processed again. Repair tasks that appear at different times should be sorted in the order of their appearance. For multiple repair tasks that appear at the same time, the processing priority coefficient XPi of each task needs to be calculated. The specific formula is:
[0151]
[0152] Among them, nbi is the target processing resource type number of the i-th repair task, mbij is the target resource number of the j-th target processing resource of the i-th repair task, mxij is the total resource number of the j-th target processing resource of the i-th repair task, λxi is the repair urgency coefficient of the i-th repair task, and the repair tasks at the same moment are sorted from high to low according to the calculated processing priority coefficient.
[0153] Specifically, it should be noted that the specific calculation formula of the repair urgency coefficient λx is:
[0154] .
[0155] Among them, Xse is the set upper limit of the wind turbine structure health loss coefficient, Xsr is the set upper limit of the breakwater structure health loss coefficient, ζe is the preset power loss upper limit, βtd and βty are the motor temperature over-limit coefficient and gearbox oil temperature over-limit coefficient respectively. The specific calculation formula is as follows:
[0156]
[0157] Among them, td, tdx, tdy, tc, tcx, and tcy are respectively the motor temperature, the lower limit of the optimal range of motor temperature, the upper limit of the optimal range of motor temperature, the gearbox oil temperature, the lower limit of the optimal range of gearbox oil temperature, and the upper limit of the optimal range of gearbox oil temperature. If the reason for the judgment generation of the repair task is that the health loss of the breakwater structure exceeds the limit, then , the values of other calculation items are 0, and the other situations are consistent with this.
[0158] When processing tasks, defensive tasks should be processed first, followed by repair tasks, and finally routine tasks. For defensive tasks at different times, they need to be sorted in the order of their appearance; for multiple tasks at the same time, the processing priority coefficient XQi of each task needs to be calculated. The specific formula is:
[0159]
[0160] Among them, nci is the target processing resource type number of the i-th defensive task, mcij is the target resource number of the j-th target processing resource of the i-th defensive task, myij is the total resource number of the j-th target processing resource of the i-th defensive task, and λfi is the defense urgency coefficient of the i-th defensive task. The defensive tasks at the same moment are sorted from high to low according to the calculated processing priority coefficient.
