[0028] The offshore photovoltaic operation and maintenance operation time determination scheme of the embodiment of the present disclosure can be implemented by an electronic device, that is, each step of the offshore photovoltaic operation and maintenance operation time determination method described below can be performed by an electronic device, and the offshore photovoltaic operation and maintenance operation time determination device described below can be configured in the electronic device. The present disclosure does not limit the device type of the electronic device, which can include a personal computer, a mobile device, a server, etc.

[0029] Figure 1 The flowchart of the method for determining the operation and maintenance time of offshore photovoltaic power generation according to an exemplary embodiment of the present disclosure is schematically shown. Figure 1 The operation and maintenance operation time determination method may include the following steps:

[0030] S10. Predicting meteorological and hydrological information of offshore photovoltaic sites within a predetermined time period in the future.

[0031] In an exemplary embodiment of the present disclosure, a future predetermined time period may be, for example, 3 days, 7 days, 10 days, 15 days, etc. from the present time. The present disclosure does not limit the specific length of the predetermined time period.

[0032] refer to Figure 2 The meteorological and hydrological information of the embodiment of the present disclosure may include wave height, wind speed, visibility, water depth, and precipitation.

[0033] According to some embodiments of the present disclosure, historical meteorological and hydrological information can be used to predict meteorological and hydrological information for a predetermined time period in the future. Specifically, a machine learning network such as LSTM (Long Short-Term Memory) can be used to obtain the prediction results of meteorological and hydrological information, and the present disclosure does not limit this process.

[0034] It should be noted that, given that meteorological and hydrological information includes wave height, wind speed, visibility, water depth, and precipitation, the prediction results may include a wave height curve within a future predetermined time period, a wind speed curve within a future predetermined time period, a visibility curve within a future predetermined time period, a water depth curve within a future predetermined time period, and a precipitation curve within a future predetermined time period.

[0035] S12. Determine multiple safe time periods for going out to sea within a predetermined time period based on the predicted meteorological and hydrological information.

[0036] Firstly, multiple wave height safety time periods in which the wave height meets the safety requirements for going out to sea within a predetermined time period can be determined from the predicted wave height curve; multiple wind speed safety time periods in which the wind speed meets the safety requirements for going out to sea within a predetermined time period can be determined from the predicted wind speed curve; multiple visibility safety time periods in which the visibility meets the safety requirements for going out to sea within a predetermined time period can be determined from the predicted visibility curve; multiple water depth safety time periods in which the water depth meets the safety requirements for going out to sea within a predetermined time period can be determined from the predicted water depth curve; multiple precipitation safety time periods in which the precipitation meets the safety requirements for going out to sea within a predetermined time period can be determined from the predicted precipitation curve.

[0037] Next, multiple wave height safety time periods, multiple wind speed safety time periods, multiple visibility safety time periods, multiple water depth safety time periods and multiple precipitation safety time periods can be combined to determine multiple safe time periods for going out to sea within a predetermined time period.

[0038] According to some embodiments of the present disclosure, the intersection of the above-mentioned safe time periods can be directly taken to obtain multiple safe time periods for going out to sea within a predetermined time period. Figure 3 FIG. 1 is a schematic diagram showing a method for determining a safe time period for going out to sea according to an embodiment of the present disclosure. Figure 3First, determine the safe time periods of wave height, wind speed, visibility, water depth, and precipitation respectively, unify the time axis, and take the intersection of these five safe time periods to obtain Figure 3 The five safe time periods for going out to sea are shown in the figure. It should be noted that Figure 3 This is merely an illustrative description and is not intended to be limiting of the present disclosure.

[0039] According to some other embodiments of the present disclosure, first, the intersection of multiple wave height safety time periods, multiple wind speed safety time periods, multiple visibility safety time periods, multiple water depth safety time periods and multiple precipitation safety time periods is taken to obtain multiple intermediate time periods.

[0040] Next, if the time interval between adjacent intermediate time periods is less than the time interval threshold, the adjacent intermediate time periods and the time interval between adjacent intermediate time periods are combined into a new intermediate time period to obtain multiple candidate time periods. The present disclosure does not limit the time interval threshold. For example, the time interval threshold can be set to the standard one-way time of a ship from the shore to the offshore photovoltaic array area.

[0041] Subsequently, the candidate time periods with a duration shorter than the shortest task duration may be eliminated from the multiple candidate time periods to determine multiple safe time periods for going to sea within the predetermined time period, wherein the shortest task is the shortest task counted among the operation and maintenance tasks involved in the disclosed scenario.

[0042] Through the combination and elimination of the above time periods, the determined safe time period for going out to sea is more in line with actual needs, and the accuracy and usability are improved.

[0043] S14. Determine the task duration of the target operation and maintenance task to be performed within the predetermined time period.

[0044] In the exemplary embodiments of the present disclosure, different operation and maintenance tasks may take different time, and the present disclosure does not limit this. The operation and maintenance tasks of the offshore photovoltaic offshore area may include but are not limited to various inspection tasks, photovoltaic component cleaning tasks, consumable material replacement tasks, etc.

[0045] S16. Compare the duration of each safe time period at sea with the duration of the task.

[0046] S18. If the duration of each sea safety time period is less than the task duration, then when the target operation and maintenance task is a divisible operation and maintenance task, the target operation and maintenance task is divided into multiple sub-target operation and maintenance tasks, and the target safety time period corresponding to each sub-target operation and maintenance task is determined from the multiple sea safety time periods, and each sub-target operation and maintenance task is allocated to the corresponding target safety time period.

[0047] In an exemplary embodiment of the present disclosure, a divisible operation and maintenance task refers to an operation and maintenance task that can be divided into multiple subtasks to be executed separately, and there is no immediate constraint on the execution time of these subtasks.

[0048] Specifically, the subtask time consumption of each sub-target operation and maintenance task can be determined, and then the corresponding target safety time period is determined from multiple sea-going safety time periods according to the subtask time consumption of each sub-target operation and maintenance task. In an exemplary embodiment of the present disclosure, the number of target safety time periods is less than or equal to the number of sub-target operation and maintenance tasks, that is, more than two sub-target operation and maintenance tasks can be executed in the same target safety time period.

[0049] According to other embodiments of the present disclosure, when the duration of each safe time period at sea is less than the task duration and the target operation and maintenance task is not a divisible operation and maintenance task, information on the failure of execution of the target operation and maintenance task within the scheduled time period can be fed back, and the target operation and maintenance task can be allocated to the next round of scheduled time period.

[0050] According to some other embodiments of the present disclosure, if only one of the multiple sea-going safety time periods has a duration greater than or equal to the task duration of the target operation and maintenance task, the target operation and maintenance task is assigned to the sea-going safety time period whose duration is greater than or equal to the task duration of the target operation and maintenance task. In other words, the only sea-going safety time period that meets the requirements is used as the time period for executing the target operation and maintenance task.

[0051] In addition, if the multiple sea-going safe time periods include multiple sea-going safe time periods whose duration is greater than or equal to the task duration of the target operation and maintenance task, the sea-going safe time period with the largest duration is determined from the multiple sea-going safe time periods whose duration is greater than or equal to the task duration of the target operation and maintenance task, and the target operation and maintenance task is assigned to the sea-going safe time period with the largest duration. In this way, the target operation and maintenance task is given the most ample execution time.

[0052] It should be noted that although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.

[0053] Furthermore, this example implementation also provides a device for determining operation and maintenance time of offshore photovoltaics.

[0054] Figure 4 The block diagram of the device for determining the operation and maintenance time of offshore photovoltaic power generation according to an exemplary embodiment of the present disclosure is schematically shown. Figure 4According to an exemplary embodiment of the present disclosure, an offshore photovoltaic operation and maintenance operation time determination device 4 may include an information prediction module 41, a time period determination module 43, a task time determination module 45, a duration comparison module 47 and a task allocation module 49.

[0055] Specifically, the information prediction module 41 can be used to predict the meteorological and hydrological information of the offshore photovoltaic offshore area within a predetermined time period in the future; wherein the meteorological and hydrological information includes wave height, wind speed, visibility, water depth, and precipitation; the time period determination module 43 can be used to determine multiple safe time periods for going out to sea within the predetermined time period according to the predicted meteorological and hydrological information; the task time determination module 45 can be used to determine the task time of the target operation and maintenance task to be executed within the predetermined time period; the duration comparison module 47 can be used to compare the duration of each safe time period for going out to sea with the task duration; the task allocation module 49 can be used to split the target operation and maintenance task into multiple sub-target operation and maintenance tasks if the duration of each safe time period for going out to sea is less than the task duration, if the target operation and maintenance task is a divisible operation and maintenance task, determine the target safe time period corresponding to each sub-target operation and maintenance task from the multiple safe time periods for going out to sea, and allocate each sub-target operation and maintenance task to the corresponding target safe time period.

[0056] According to an exemplary embodiment of the present disclosure, the time period determination module 43 can be configured to: determine from the predicted wave height curve a plurality of wave height safety time periods within a predetermined time period in which the wave height meets the safety requirements for going to sea; determine from the predicted wind speed curve a plurality of wind speed safety time periods within a predetermined time period in which the wind speed meets the safety requirements for going to sea; determine from the predicted visibility curve a plurality of visibility safety time periods within a predetermined time period in which the visibility meets the safety requirements for going to sea; determine from the predicted water depth curve a plurality of water depth safety time periods within a predetermined time period in which the water depth meets the safety requirements for going to sea; determine from the predicted precipitation curve a plurality of precipitation safety time periods within a predetermined time period in which the precipitation meets the safety requirements for going to sea; and combine a plurality of wave height safety time periods, a plurality of wind speed safety time periods, a plurality of visibility safety time periods, a plurality of water depth safety time periods and a plurality of precipitation safety time periods to determine a plurality of safe time periods for going to sea within a predetermined time period.

[0057] According to an exemplary embodiment of the present disclosure, the time period determination module 43 can be configured as follows: taking the intersection of multiple wave height safety time periods, multiple wind speed safety time periods, multiple visibility safety time periods, multiple water depth safety time periods and multiple precipitation safety time periods to obtain multiple intermediate time periods; if the time interval between adjacent intermediate time periods is less than the time interval threshold, then combining the adjacent intermediate time periods and the time intervals between adjacent intermediate time periods into a new intermediate time period to obtain multiple candidate time periods; eliminating the candidate time periods whose duration is less than the shortest task duration from the multiple candidate time periods to determine multiple safe time periods for going out to sea within the predetermined time period.

[0058] According to an exemplary embodiment of the present disclosure, the task allocation module 49 can be configured to: determine the subtask duration of each sub-target operation and maintenance task; determine the corresponding target safety time period from multiple sea safety time periods according to the subtask duration of each sub-target operation and maintenance task; wherein the number of target safety time periods is less than or equal to the number of sub-target operation and maintenance tasks.

[0059] According to an exemplary embodiment of the present disclosure, the task allocation module 49 can also be configured to: when the duration of each safe time period at sea is less than the task duration and when the target operation and maintenance task is not a divisible operation and maintenance task, feedback information on the failure of execution of the target operation and maintenance task within the scheduled time period is provided, and the target operation and maintenance task is allocated to the next round of scheduled time period.

[0060] According to an exemplary embodiment of the present disclosure, the task allocation module 49 can also be configured as follows: if only one of the multiple safe time periods for going out to sea has a duration greater than or equal to the task duration of the target operation and maintenance task, the target operation and maintenance task will be allocated to the safe time period for going out to sea whose duration is greater than or equal to the task duration of the target operation and maintenance task.

[0061] According to an exemplary embodiment of the present disclosure, the task allocation module 49 can also be configured as follows: if multiple safe time periods for going out to sea include multiple safe time periods for going out to sea whose duration is greater than or equal to the task duration of the target operation and maintenance task, then the safe time period for going out to sea with the longest duration is determined from the multiple safe time periods for going out to sea whose duration is greater than or equal to the task duration of the target operation and maintenance task, and the target operation and maintenance task is allocated to the safe time period for going out to sea with the longest duration.
