[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application, and are not used to limit the present application.

[0045] In order to better understand the technical solutions of the present application, the following will be described in detail in combination with the drawings in the specification and the specific embodiments.

[0046] The main solution of the embodiment of the present application is: collecting the upstream inflow and the initial load of the hydropower station at the initial collection time; when the upstream inflow is greater than a preset threshold, predicting the future load at the future time according to the initial load; when the upstream inflow is less than or equal to the preset threshold, determining the change rate of the upstream inflow relative to the upstream inflow at the last collection time; judging whether the change rate is within a preset range, and determining the future load at the future time according to the judgment result.

[0047] Hydropower, as a clean energy, is widely used around the world, with the advantages of renewable, clean, relatively low cost, etc. Hydropower station is a facility that converts water energy into electric energy. It drives the turbine through the power of water flow, and the turbine in turn drives the generator to generate electricity. The current operator needs to monitor the water regime and load data in real time, and manually judge whether the load at the future time needs to be adjusted, which is low in efficiency and easy to make mistakes.

[0048] The present application collects the upstream inflow and initial load of the hydropower station at the initial collection time. When the upstream inflow is greater than the preset threshold, the future load at the future time is predicted according to the initial load. When the upstream inflow is less than or equal to the preset threshold, the change rate of the upstream inflow relative to the inflow at the last collection time is determined, and then it is judged whether the change rate is within the preset range. The future load at the future time is determined according to the judgment result. When the upstream inflow at the initial collection time is greater than the preset threshold, it means that the upstream inflow is too large, and the initial load at the initial collection time needs to be improved. The future load at the future time is predicted. When the upstream inflow is less than or equal to the preset threshold, it is judged whether the change rate of the inflow is within the preset range, that is, whether the upstream inflow at the initial collection time has a sudden change. If there is a sudden change, the initial load at the initial collection time needs to be adjusted, so as to automatically and effectively judge whether the initial load needs to be adjusted, accurately predict the future load at the future time, and eliminate the dependence on artificial experience.

[0049] It should be noted that the execution subject of the present application can be a control system in the hydropower station, which can perform data collection, water flow control, power generation equipment control, etc.

[0050] Based on this, the present application embodiment provides a load adjustment method, which refers to Figure 1 , Figure 1 The flowchart of the first embodiment of the load adjustment method of the present application is shown.

[0051] In this embodiment, the load adjustment method comprises the following steps:

[0052] Step S10: Collect the upstream inflow and initial load of the hydropower station at the initial collection time.

[0053] It can be understood that the upstream inflow refers to the natural water flow through the hydropower station or the reservoir control section from the upstream of the river, which can be collected by a flow meter. Specifically, a plurality of flow meters can be arranged on the cross section of the river, and these flow meters cover the entire section. For the case where the flow velocity and water depth are relatively uniform, the upstream inflow can be obtained by adding the flow values measured by all flow meters and dividing the number of flow meters. For the case where the flow velocity and water depth are not uniform, the flow can be weighted and summed according to the area proportion represented by each point, and the weight can be distributed according to the area (width multiplied by depth) of the position of each flow meter. The initial load of the generator set can be collected by a load sensor.

[0054] It should be understood that the initial collection time can be the last time when the upstream inflow and the load are collected before the current time. The flow meter and the load sensor can be set to collect the upstream inflow and the initial load every interval of 10 minutes, 15 minutes, etc.

[0055] Step S20: When the upstream inflow is greater than the preset threshold, predicting the future load at the future time according to the initial load.

[0056] It can be understood that when the upstream inflow is greater than the preset threshold, it means that the upstream inflow is too large, and the future load at the future time will also be large. At this time, the initial load at the initial collection time can be increased to obtain the future load at the future time.

[0057] Further, in order to set the preset threshold, before the step S20, the method further includes: obtaining a historical flow set of the hydropower station in a historical time period; and taking the maximum historical flow in the historical flow set as the preset threshold.

[0058] It should be understood that the historical time period can be a time period before the initial collection time, for example, the previous day, the previous two days. The historical flow set of the hydropower station in the historical time period can be obtained. The historical flow set can include historical flows at a plurality of collection times in the historical time period. The maximum historical flow in the historical flow set is taken as the preset threshold.

[0059] Further, in order to determine the future time, before the step S20, the method further includes: determining the path length between the upstream monitoring point and the reservoir of the hydropower station; calculating the time length for the upstream water to reach the reservoir according to the path length and the flow velocity; and determining the future time according to the time length and the initial collection time.

[0060] It can be understood that the upstream monitoring point can be a specific point upstream, and the path length refers to the actual distance from the upstream monitoring point to the reservoir inlet of the hydropower station. The distance is not a simple straight-line distance, but an actual path length along the river channel, which can be estimated by map software or a geographic information system. The flow velocity can be obtained by field measurement. The flow velocity can be different in different river sections, especially between rapids, waterfalls or flat river sections.

[0061] In a specific implementation, the time length for upstream water to reach the reservoir can be the path length divided by the flow velocity. For example, the distance from the upstream monitoring point to the reservoir inlet of the hydropower station is 10 kilometers, and the average flow velocity of the river section is 10 kilometers per hour. Then, the time for upstream water to reach the reservoir of the hydropower station is about 1 hour. The future time can be the initial collection time plus the time length. For example, the initial collection time is 5 o'clock, and the future time is 6 o'clock.

[0062] Step S30: When the upstream inflow is less than or equal to the preset threshold, determining a change rate of the upstream inflow relative to the inflow at the previous collection time.

[0063] It can be understood that when the upstream inflow is less than or equal to the preset threshold, it is not determined whether the initial load needs to be adjusted. At this time, the change rate of the upstream inflow at the initial collection time relative to the inflow at the previous collection time can be determined. The previous collection time can be the collection time of the flowmeter before the initial collection time. For example, the inflow at the previous collection time is 500 cubic meters per second, and the upstream inflow at the initial collection time is 1000 cubic meters per second. The change rate is 100%.

[0064] Step S40: determining whether the change rate is within a preset range, and determining the future load at the future time according to the determination result.

[0065] It should be understood that the preset range can be a preset range, which can be less than -20% and greater than 20%. When the change rate is within the preset range, it indicates that the inflow has changed. At this time, the initial load needs to be adjusted. When the change rate is positive, it indicates that the inflow increases, and the load also needs to be increased. When the change rate is negative, it indicates that the inflow decreases, and the load also needs to be decreased. When the change rate is not within the preset range, it indicates that the inflow has not changed. At this time, the initial load does not need to be adjusted, and the future load at the future time can be equal to the initial load.

[0066] The embodiment collects the upstream inflow and the initial load at the initial collection time of the hydropower station, predicts the future load at the future time according to the initial load when the upstream inflow is greater than the preset threshold, determines the change rate of the upstream inflow relative to the inflow at the last collection time when the upstream inflow is less than or equal to the preset threshold, further determines whether the change rate is within the preset range, and determines the future load at the future time according to the determination result. When the upstream inflow at the initial collection time is greater than the preset threshold, it means that the upstream inflow is too large, and the initial load at the initial collection time needs to be improved to predict the future load at the future time. When the upstream inflow is less than or equal to the preset threshold, it is determined whether the change rate of the upstream inflow is within the preset range, that is, whether the upstream inflow at the initial collection time has a sudden change. If there is a sudden change, the initial load at the initial collection time needs to be adjusted, so that it can be automatically and effectively determined whether the initial load needs to be adjusted, the future load at the future time can be accurately predicted, and the dependence on artificial experience is eliminated.

[0067] Reference Figure 2 , Figure 2 The flowchart of the second embodiment of the load adjustment method is shown.

[0068] Based on the first embodiment, in the present embodiment, the step S20 comprises:

[0069] Step S201: When the upstream inflow is greater than the preset threshold, the upstream inflow is input into the preset long short-term memory network model to obtain a first load adjustment amplitude.

[0070] It can be understood that when the upstream inflow is greater than the preset threshold, it means that the upstream inflow is too large, and the load needs to be improved at this time. Specifically, the upstream inflow can be preprocessed, for example, normalized or standardized, and the processed inflow is input into the preset long short-term memory network model to obtain a first load adjustment amplitude, which refers to the proportion of the initial load improvement.

[0071] In a specific implementation, historical data such as inflow, rainfall, and load at different times can be collected, and the historical data can be normalized or standardized. The processed data is converted into a time series format suitable for input of the initial long short-term memory network model. The input can be the inflow at the current time, and the output can be the load at the next time. The current time and the next time are historical times. The initial long short-term memory network model is trained using the above data set to obtain the preset long short-term memory network model.

[0072] Step S202: predicting the future load at the future time according to the first load adjustment amplitude and the initial load.

[0073] It should be understood that when the upstream inflow is greater than the preset threshold, the future load at the future time needs to be increased, and the future load can be the initial load plus the initial load multiplied by the first load adjustment amplitude. For example, the initial load is 100 megawatts, and the first load adjustment amplitude is 10%, and then the future load is 110 megawatts.

[0074] In the embodiment, when the upstream inflow is greater than the preset threshold, the upstream inflow is input into the preset long short-term memory network model to obtain the first load adjustment amplitude, and then the future load at the future time is predicted according to the first load adjustment amplitude and the initial load. In the embodiment, when the upstream inflow is greater than the preset threshold, the first load adjustment amplitude to be adjusted at the future time is predicted through the preset long short-term memory network model, the future load at the future time can be accurately predicted, and the dependence on artificial experience is eliminated.

[0075] Reference Figure 3 , Figure 3 FIG. 1 is a flowchart of a load adjustment method according to a third embodiment of the present application.

[0076] Based on the above embodiments, in the embodiment, the step S40 comprises:

[0077] Step S401: When the change rate is in the preset range, the upstream inflow is input into the preset long short-term memory network model to obtain the second load adjustment amplitude.

[0078] It should be understood that when the change rate is in the preset range, the change rate can be less than -20% and greater than 20%. When the change rate is in the preset range, it indicates that the inflow has a mutation, and at this time, the upstream inflow can be input into the preset long short-term memory network model to obtain the second load adjustment amplitude.

[0079] Step S402: The future load at the future time is predicted according to the second load adjustment amplitude and the initial load.

[0080] It should be understood that the initial load can be adjusted according to the second load adjustment amplitude to obtain the future load at the future time. Specifically, when the change rate is a positive value, the initial load needs to be increased to obtain the future load; and when the change rate is a negative value, the initial load needs to be reduced to obtain the future load. For example, the initial load is 100 megawatts, the first load adjustment amplitude is 20%, and the change rate is a positive value, and then the future load is 120 megawatts.

[0081] Step S403: When the change rate is not in the preset range, the initial load is taken as the future load at the future time.

[0082] In a specific implementation, when the rate of change is not within the preset range, for example, the rate of change is greater than or equal to -20% and less than or equal to 20%, it indicates that the rate of change has not undergone a sudden change. At this time, the initial load may not be adjusted, that is, the initial load is used as the future load at a future moment.

[0083] Furthermore, in order to verify the predicted future load, in this embodiment, after step S40, it also includes: determining the load change trend of the future load, and determining the water inflow change trend of the upstream water flow; judging whether the future load is abnormal based on the water inflow change trend and the load change trend.

[0084] It is understood that the load change trend can be the change trend from the initial load to the future load, such as an increase or decrease. The water flow change trend can be the change trend from the water flow at the previous collection time to the water flow at the initial collection time. Due to the short interval between collection times, the above water flow change trend can be used as the change trend from the initial collection time to the next time.

[0085] It should be understood that, under normal circumstances, an increasing water flow trend corresponds to an increasing load trend; a decreasing water flow trend corresponds to a decreasing load trend. Therefore, it is possible to determine whether the load trend is abnormal based on the water flow trend, and further determine whether the predicted future load is abnormal. If the future load is abnormal, the load adjustment amplitude can be re-predicted using a preset long-short-term memory network model, or the future load can be manually calibrated and the calibrated load reported to the supervision platform.

[0086] In the specific implementation, refer to Figure 4 , Figure 4 This is the overall structural diagram of an embodiment of the load adjustment method of this application, as shown in FIG. Figure 4 As shown in the figure, the sensor layer is used to collect upstream water volume, load and other data. The data processing layer can be used to clean the collected data, fuse the data and then perform feedback optimization, that is, adjust the initial load. The execution layer is used to send load control instructions according to the future load to control the future load. The platform interaction layer is used for self-calibration and automatic reporting, that is, to determine whether the future load is abnormal and report the calibrated load to the supervision platform.

[0087] When the result of the judgment is that the change rate is within the preset range, the upstream inflow is input into the preset long short-term memory network model to obtain a second load adjustment amplitude, and then the future load at the future time is predicted according to the second load adjustment amplitude and the initial load. When the change rate is not within the preset range, the initial load is taken as the future load at the future time. When the result of the judgment is that the change rate is within the preset range, that is, when the upstream inflow has a mutation, the future load at the future time is predicted according to the second load adjustment amplitude and the initial load. When the upstream inflow has no mutation, the initial load does not need to be adjusted, so that it can be automatically and effectively judged whether the initial load needs to be adjusted, the future load at the future time can be accurately predicted, and the dependence on artificial experience is eliminated.

[0088] With reference to Figure 5 , Figure 5 FIG. 1 is a structural block diagram of a load adjustment device according to an embodiment of the present application.

[0089] As shown in FIG. 2, the load adjustment device according to the embodiment of the present application comprises: Figure 5

[0090] A data acquisition module 10 is configured to acquire an upstream inflow and an initial load of a hydropower station at an initial acquisition time.

[0091] A load adjustment module 20 is configured to predict a future load at a future time according to the initial load when the upstream inflow is greater than a preset threshold.

[0092] A change rate determination module 30 is configured to determine a change rate of the upstream inflow relative to an inflow at a previous acquisition time when the upstream inflow is less than or equal to the preset threshold.

[0093] The load adjustment module 20 is further configured to judge whether the change rate is within a preset range, and determine the future load at the future time according to the result of the judgment.

[0094] ​The embodiment collects the upstream inflow and the initial load at the initial collection time of the hydropower station, predicts the future load at the future time according to the initial load when the upstream inflow is greater than the preset threshold, determines the change rate of the upstream inflow relative to the inflow at the last collection time when the upstream inflow is less than or equal to the preset threshold, and then determines whether the change rate is within the preset range, and determines the future load at the future time according to the determination result. When the upstream inflow at the initial collection time is greater than the preset threshold, it means that the upstream inflow is too large, and the initial load at the initial collection time needs to be improved to predict the future load at the future time. When the upstream inflow is less than or equal to the preset threshold, it is determined whether the change rate of the inflow is within the preset range, that is, whether the upstream inflow at the initial collection time has a sudden change. If there is a sudden change, the initial load at the initial collection time needs to be adjusted, so that it can automatically and effectively determine whether the initial load needs to be adjusted, accurately predict the future load at the future time, and eliminate the dependence on artificial experience.
