[0002] During the operation of a hydropower station, gate opening control is one of the key links to ensure safe and stable operation of the power station. The gate opening not only affects the power generation efficiency of the hydropower station, but is also directly related to the safety of the power station and the service life of the equipment.

[0003] The existing monitoring methods for the gate opening of power stations often use the design standards at the beginning of the gate construction as the monitoring threshold. For example, when the water level is at a certain height, if the gate opening is monitored to be higher than the fixed monitoring threshold, an excessive opening alarm will be issued. Therefore, the existing monitoring methods fail to fully consider the dynamic changing factors of the gate in actual operation, such as the water level change range, power generation task volume, and the life status of the gate, etc., making it difficult to fully reflect the operating status of the gate, which can easily lead to misjudgment of the monitoring results. Summary of the invention

[0028] In this step, by real-time monitoring of the water levels upstream and downstream of the hydropower station, combined with historical hydrological data and weather forecasts, the water level change range within the set time can be accurately determined, including the highest and lowest water levels; this helps the hydropower station to formulate response measures in advance to avoid safety risks caused by a sharp rise or fall in water levels, and also provides a scientific basis for the water resources management and scheduling of the hydropower station; based on the hydropower station's scheduling plan, historical electricity consumption data and seasonal electricity consumption patterns, it is possible to predict electricity demand in the future, thereby reasonably adjusting the power generation task volume; this demand-based power generation task allocation method not only ensures the stability and economy of power supply, but also helps to improve the operating efficiency and energy utilization of the hydropower station. ; When allocating power generation tasks, consider the status of other power generation equipment in the hydropower station to ensure that the allocation of power generation tasks is reasonable and feasible; help improve equipment utilization, reduce power supply interruptions caused by equipment failures, and also enhance the overall safety of the hydropower station; when determining the power generation task, comply with national and local environmental protection policies to ensure that the power generation task meets environmental protection requirements; help the hydropower station achieve sustainable development, reduce the impact on the environment, and improve social recognition; this step improves the operating efficiency and energy utilization of the hydropower station by accurately grasping water level changes and optimizing the allocation of power generation tasks, while also enhancing the safety and environmental protection of the hydropower station, providing strong support for the sustainable development of the hydropower station.

When allocating tasks, high-efficiency units should be given priority; Equipment status: Consider the maintenance status and availability of generator sets to avoid assigning tasks to units that are under maintenance or have faults; Environmental conditions: Consider factors such as water temperature and water flow rate to select the most suitable generator set; Calculate the required flow rate according to the power generation task assigned to each generator set; Determine the expected operating opening of each gate based on the calculated flow demand and the gate design standard information; Verify the expected operating opening to ensure that the calculated gate opening is within the design range of the gate, that is, it does not exceed the maximum allowable opening and the minimum allowable opening; if the calculated opening exceeds the design range, it needs to be adjusted; according to the real-time monitored water level and flow data, dynamically adjust the gate opening to ensure that the actual operating status is consistent with the expected operating status.

[0030] In this step, by decomposing the power generation task within the set time according to the time granularity, the specific power generation demand at each time point or time period can be accurately determined, thereby more accurately guiding the prediction and setting of the gate opening; comprehensively considering the capacity, efficiency, equipment status and environmental conditions of the generator set, the total power generation task is reasonably allocated to each generator set, ensuring the optimal allocation and efficient utilization of resources; the expected operating opening is strictly checked to ensure that it is within the design range of the gate, that is, it does not exceed the maximum allowable opening and the minimum allowable opening, effectively avoiding equipment damage or safety risks caused by excessive or too small opening; the gate opening is dynamically adjusted according to the real-time monitored water level and flow data to ensure the consistency between the actual operating status and the expected operating status, further enhancing the safety and stability of the hydropower station operation; Through this step, the expected operating opening of each gate within the set time can be planned in advance, providing clear work guidance and plans for the hydropower station operation and maintenance personnel, reducing the blindness and arbitrariness in the operation and maintenance process; when the calculated gate opening exceeds the design range or there is a deviation between the actual operating status and the expected status, an early warning can be issued in time to remind the operation and maintenance personnel to take corresponding measures to adjust and correct, thereby avoiding potential operating risks and failures; by reasonably allocating power generation tasks and accurately controlling the gate opening, the power generation efficiency and energy utilization rate of the hydropower station can be maximized, unnecessary energy waste and emissions can be reduced, and the goal of energy conservation and emission reduction can be achieved; the implementation of this step can also help hydropower stations better plan and arrange operation and maintenance work, and reduce economic losses and cost expenditures caused by equipment failures or downtime for maintenance.

[0031] S4. For each gate, use the gate life status information and the water level change interval as dual-limit positioning conditions, locate it in the pre-built gate risk opening database, and obtain the gate risk opening interval; determine the upper limit of the gate risk opening interval according to the upper limit of the water level change interval and the gate life status information; determine the lower limit of the gate risk opening interval according to the lower limit of the water level change interval and the gate life status information; The method for constructing a gate risk opening database includes: Collect basic design information of each gate of the hydropower station, gate life status information, historical water level change data of the hydropower station and power generation task data; Design the database structure, including gate information table, water level change table, power generation task table and risk opening table; these tables can store the above collected data and model calculation results; Enter the collected data into the database and integrate it to ensure the consistency and integrity of the data; Calculate the risk opening ranges under different water level change intervals and gate life states; these intervals will be used as key information in the database for subsequent positioning and risk assessment; As the operation time of the hydropower station increases and the gate status changes, the data in the database needs to be updated regularly; Establish a database backup mechanism to ensure data security and recoverability; Determine the specific water level conditions currently faced by the gate based on the water level change range; Determine the current gate life status according to the gate life status information; In the gate risk opening database, query according to the current gate water level change range and life status information to find matching records; According to the upper limit of the water level change range and the gate life status information, the upper limit of the corresponding gate risk opening range is obtained from the database; According to the lower limit of the water level change range and the gate life status information, the lower limit of the corresponding gate risk opening range is obtained from the database.

[0032] In this step, by using the gate life status information and the water level change range as the dual-limit positioning conditions, the records matching the current gate status can be accurately found in the gate risk opening database, so as to more accurately determine the gate risk opening range; compared with the traditional method of using the design standard as the monitoring threshold, it can better reflect the dynamic change factors of the gate in actual operation and improve the accuracy of risk assessment; using database technology, real-time monitoring and dynamic updating of the gate risk opening are realized; as the operating time of the hydropower station increases and the gate status changes, the data in the database will be updated accordingly, thereby ensuring the risk assessment The timeliness and accuracy of the results; the obtained gate risk opening range can provide strong decision-making support for the operation and maintenance management of the hydropower station; the operation and maintenance personnel can formulate reasonable gate opening control strategies and maintenance plans based on the risk assessment results, so as to ensure the safe and stable operation of the hydropower station; at the same time, this also helps to extend the service life of the gate and reduce the operation and maintenance costs; step S4 introduces the gate risk opening database to achieve accurate assessment and dynamic monitoring of gate opening risks, improve the accuracy of risk assessment, enhance the real-time and dynamic nature of monitoring, optimize operation and maintenance management decisions, and improve data management and security.

[0034] In this step, by calculating the deviation between the expected operating opening and the gate risk opening range, the operating risk of the gate can be accurately quantified, avoiding the misjudgment caused by the traditional fixed threshold method; the method takes into account dynamic factors such as the water level change range and the gate life status, which can more comprehensively reflect the actual operating status of the gate and improve the accuracy and reliability of risk assessment; the risks are divided into different levels, which is convenient for managers to take corresponding countermeasures according to the risk level, thereby improving the safety and stability of power station operation; through normalization processing, the risk anomaly degree is standardized to a value between 0 and 1, which is convenient for statistical analysis and visual display, and improves the operability and interpretability of the data; timely discovery and quantification of the gate operation risk is helpful to take preventive maintenance measures in advance, extend the service life of the gate, and reduce downtime and economic losses caused by equipment failure; based on the assessment results of the risk anomaly degree, the dispatching strategy of the hydropower station can be optimized, the power generation efficiency can be improved, and the safe and stable operation of the power station can be ensured.

[0036] In this step, by collecting the risk anomaly degree data of all gates in the hydropower station, and organizing and analyzing them, the risk status of the gates of the entire hydropower station can be fully and objectively understood; it is helpful for operation and maintenance managers to grasp the safe operation status of the hydropower station as a whole; by calculating the mean, median, standard deviation, maximum and minimum values ​​of the risk anomaly degree, the risk level of the hydropower station gate can be accurately quantified; it not only reflects the overall risk status, but also reveals the discrete degree and extreme conditions of the risk, providing strong support for risk management and decision-making; dividing the risk anomaly degree into different intervals and calculating the number of gates in each interval can intuitively display the distribution of the risk anomaly degree; it is helpful for operation and maintenance managers to identify high-risk areas and low-risk areas, so as to take targeted risk management measures; by analyzing the risk anomaly degree The correlation between the degree of normality and factors such as gate design standards, life status, water level change range, and power generation tasks can identify the key factors affecting the risk; it helps operation and maintenance managers to have a deep understanding of the root causes of risks and thus formulate more effective risk management strategies; based on the results of statistical analysis, operation and maintenance managers can interpret the risk status of hydropower station gates more scientifically and formulate risk response measures accordingly; this not only improves the pertinence and effectiveness of risk management, but also provides a strong guarantee for the stable operation of hydropower stations; step S6 provides scientific and effective support for the risk management of hydropower station gates through comprehensive data collection, precise statistical analysis, visual display of risk distribution, and identification of key factors; it not only helps to improve the safe operation level of hydropower stations, but also provides a strong basis for the decision-making of operation and maintenance managers.
