[0002] Water conservancy projects are important projects related to the national economy and people's livelihood. The technologies of their management methods and systems have been continuously developing with the continuous progress of science and technology. In the management of water conservancy projects, traditional methods often rely on manual monitoring and empirical judgment. This method is not only inefficient but also difficult to accurately reflect the real-time operation status of water conservancy projects.

[0003] Specifically, due to relying on manual monitoring, the traditional method leads to inaccurate monitoring data. And due to the limitations of monitoring means, the traditional method often cannot reflect the operation status of water conservancy projects in real time, resulting in a lag in decision-making.

At the same time, through reasonable module division and equipment configuration, the stability and reliability of the system can be ensured.

[0080] Referring to Figure 3 As shown, in this implementation plan: the water level monitoring information includes the basic water level, the minimum water level, and the maximum water level;

[0081] The flow rate monitoring information includes the flow rate per second and the flow coefficient;

[0082] The power monitoring information includes the input hydraulic power, the output hydraulic power, the maximum hydraulic efficiency, and the minimum hydraulic efficiency;

[0083] According to the flow rate per second and the flow coefficient, obtain the characteristics of the influence of the flow rate on the water level;

[0084] According to the characteristics of the influence of the water level and the basic water level, obtain the current water level.

[0085] The calculation formula of the water level describing the relationship between the water level and the flow rate is as follows:

[0086] ;

[0087] Where:

[0088] W is the current water level, and W represents the water depth in meters at each monitoring point of the water conservancy project;

[0089] L is the flow rate per second, and L represents the flow rate of the water flow through each monitoring point of the water conservancy project in cubic meters per second;

[0090] I is the flow coefficient, and I reflects the degree of obstruction and promotion of the water conservancy project structure to the water flow. When the water conservancy project structure is put into use, it is obtained through experimental determination and simulation and stored in the system;

[0091] W0 is the basic water level, and W0 represents the water depth in meters at each monitoring point of the water conservancy project when there is no flow;

[0092] The result of is an intermediate quantity related to the flow rate and the water level, and reflects the degree of influence of the water conservancy project structure on the water level under a specific flow rate.

[0093] The calculation of the water level describing the relationship between the water level and the flow rate in this embodiment, that is , in fluid mechanics, the relationship between the flow rate L per second and the current water level W is usually complex. Especially in hydraulic engineering structures with specific geometries, these structures can impede and promote the water flow, resulting in a non-linear relationship between the flow rate and the water level. To approximately describe this non-linear relationship, the result of is processed by taking the square root. This can obtain an intermediate quantity related to both the flow rate and the water level, which reflects the impact of the hydraulic engineering structure on the water level at a specific flow rate. Specifically, when the flow rate L per second increases, the result also increases. However, due to the square root operation, the rate of increase will gradually slow down. This means that as the flow rate increases, the rate of the water level rising will gradually slow down, thereby reflecting the obstructive effect of the hydraulic engineering structure on the water flow. On the contrary, if the hydraulic engineering structure promotes the water flow, then the result of taking the square root will cause the water level to rise relatively faster than in the case of obstruction. Therefore, the method of taking the square root can not only approximately describe the non-linear relationship between the flow rate and the water level but also reflect the impact of the hydraulic engineering structure on the water flow;

[0094] accurately describes the basic relationship between the water level and the flow rate in hydraulic engineering, providing a solid physical basis for the digital twin model. Through , the system can simulate and predict the water level changes at different flow rates in real time, and combined with the real-time data of multiple monitoring control points, it can quickly calculate the water level at each point, thus realizing the comprehensive monitoring of the hydraulic engineering. This not only improves the monitoring efficiency but also ensures the accuracy and timeliness of the data;

[0095] Through , the system can analyze the water level changes at different flow rates, and then optimize the allocation of water resources. In addition, in, the flow coefficient I is simulated based on the average ratio of the flow rates with and without obstacles at different water levels of different hydraulic engineering structures, so that the system can adapt to different hydraulic engineering conditions, enhancing the stability and adaptability of the system.

[0096] Referring to Figure 3 as shown, in this implementation plan: Based on the flow rate per second and the maximum preset flow rate, obtain the flow factor;

[0097] According to the current water level, the minimum water level, and the maximum water level, obtain the water level factor;

[0098] According to the input hydraulic power and the output hydraulic power, obtain the power factor;

[0099] According to the flow factor, the water level factor, and the power factor, obtain the current hydraulic efficiency.

[0100] The calculation formula for the hydraulic efficiency to evaluate the performance of a hydraulic engineering project is as follows:

[0101] ;

[0102] Where:

[0103] P is the current hydraulic efficiency;

[0104] L max is the maximum preset flow rate, L max represents the maximum flow rate manually set for each monitoring point of the hydraulic engineering project when the hydraulic engineering structure is put into use;

[0105] W min is the minimum water level, W min reflects the minimum value of the water level monitored at each monitoring point of the hydraulic engineering project during historical monitoring after the hydraulic engineering structure is put into use;

[0106] W max is the maximum water level, W max reflects the minimum value of the water level monitored at each monitoring point of the hydraulic engineering project during historical monitoring after the hydraulic engineering structure is put into use;

[0107] G in is the input hydraulic power;

[0108] G out is the output hydraulic power;

[0109] The result of is a flow factor reflecting the proportional relationship between the actual flow rate and the preset maximum flow rate;

[0110] The result of is a water level factor used to evaluate the operating efficiency of each monitoring point of the hydraulic engineering project at different water levels;

[0111] The result of is a power factor evaluating the loss situation of each monitoring point of the hydraulic engineering project during the energy conversion process.

[0112] In this embodiment The result of is the flow factor, which is used to quantify the actual flow rate per second, and this ratio reflects the flow condition of the hydraulic engineering project during actual operation. It is an important parameter for evaluating its operating efficiency. Through the flow factor, it is possible to understand whether the hydraulic engineering project is in a full-load, light-load, or over-load state. The result of is the water level factor, which is used to evaluate the operating efficiency of the hydraulic engineering project at different water levels. It calculates through and The relative position between them is obtained. The water level factor reflects the operating conditions of the water conservancy project within the water level change range. For a water conservancy project with a water level regulation function, understanding its operating efficiency at different water levels helps provide a numerical basis and improve the overall operating efficiency. The result is the power factor, which is used to quantify the proportional relationship between the input and output hydraulic power of the water conservancy project. This ratio reflects the efficiency of the water conservancy project during the energy conversion process. Through the power factor, the loss situation of the water conservancy project during the energy conversion process can be evaluated.

[0113] When evaluating the efficiency of the water conservancy project, if this ratio is directly used without taking the square root, then due to the relationship that hydraulic power is proportional to the square of the flow rate, even if there are minor fluctuations in the flow rate and water head, the power factor will change significantly. This is not conducive to stably evaluating the operating efficiency of the water conservancy project. To solve this problem, the square root method is used to process the result.

[0114] The purpose of multiplying the three parts in

[0115] - the flow factor, the water level factor, and the power factor - is to comprehensively evaluate the current hydraulic efficiency P of the water conservancy project. Multiple factors such as the flow rate, water level, and power in the actual operation of the water conservancy project are considered. By multiplying these three parts, a numerical value reflecting the overall operating efficiency of the water conservancy project can be obtained. This numerical value helps to more comprehensively understand the operating conditions of the water conservancy project.

[0116] Refer to Figure 1 and Figure 3 As shown, in this implementation plan: Based on the difference between the previous basic water level feature and the current water level, the water level adjustment value is obtained.

[0117] According to the water level adjustment value and the current water level, the water level adjustment factor is obtained.

[0118] According to the current hydraulic efficiency, the maximum hydraulic efficiency, the minimum hydraulic efficiency, and the preset hydraulic efficiency, the power adjustment factor is obtained.

[0119] According to the water level adjustment factor and the power adjustment factor, the comprehensive adjustment factor is obtained.

[0120] According to the comprehensive adjustment factor and the flow rate per second, the adjusted flow rate per second is obtained.

[0121] The calculation formula for the flow rate used for feedback adjustment is as follows:

[0122] ;

[0123] Wherein:

[0124] L new is the adjusted flow rate per second;

[0125] Pa is the preset hydraulic efficiency. Pa represents the value manually set for each monitoring point of the hydraulic engineering structure when the hydraulic engineering structure is put into use, including the maximum preset flow rate L max , and substituting it into the calculation formula to obtain the preset value;

[0126] P max is the maximum hydraulic efficiency. P max reflects the maximum value of the hydraulic efficiency monitored at each monitoring point of the hydraulic engineering structure during the historical monitoring after the hydraulic engineering structure is put into use;

[0127] P min is the minimum hydraulic efficiency. P min reflects the minimum value of the hydraulic efficiency monitored at each monitoring point of the hydraulic engineering structure during the historical monitoring after the hydraulic engineering structure is put into use;

[0128] △W is the water level adjustment value. △W reflects the difference between the current and the previous monitored water levels at each monitoring point of the hydraulic engineering structure, that is, the difference between W old -W, where W old is the previous water level;

[0129] The result is a comprehensive adjustment factor calculated based on the influence of the hydraulic efficiency deviation and the adjacent two water level deviations on the current water level to calculate the required adjusted flow rate ratio;

[0130] Based on the result of the adjusted flow rate per second L new , and the adjusted flow rate per second L new is used as the adjusted flow rate per second L for the next adjustment. The control center transmits the result of the adjusted flow rate per second L new to each monitoring point of the hydraulic engineering structure for dynamic control and execution.

[0131] The calculation part of this embodiment aims to calculate an adjustment factor according to the deviation between the current hydraulic efficiency P and the preset hydraulic efficiency Pa, and the deviation between the achieved maximum hydraulic efficiency P max and the minimum hydraulic efficiency P min . This adjustment factor will be used to adjust the original flow rate per second L to obtain the adjusted flow rate per second L new, thus realizing the feedback regulation of hydraulic efficiency. Such a calculation method is used to linearly reflect the influence of hydraulic efficiency deviation on flow adjustment. When the current hydraulic efficiency P is close to the preset hydraulic efficiency Pa, the adjustment factor is close to 1 and the flow adjustment amount is small. When the current hydraulic efficiency P is far from the preset hydraulic efficiency Pa, the adjustment factor will be significantly greater than and less than 1, and the flow adjustment amount is large. This design helps the system quickly converge to the preset hydraulic efficiency Pa. The calculation part further considers the influence of the water level deviation between two adjacent times on the current water level when multiplying with , and then calculates a comprehensive adjustment factor. This adjustment factor is directly multiplied by the original flow rate L per second to obtain the adjusted flow rate L per second. new , and determines the direction and amplitude of flow adjustment, which is the key to realizing feedback regulation;

[0132] Adjusted flow rate L per second new The result realizes the closed-loop control of the flow rate by introducing the preset hydraulic efficiency Pa and the water level adjustment value △W. When the actual current hydraulic efficiency P deviates from the preset hydraulic efficiency Pa, the system can automatically adjust the adjusted flow rate L per second. new , to restore the performance of the hydraulic project. The closed-loop control system can resist the influence of external disturbances and uncertain factors, enhancing the robustness of the system. Through the adjusted flow rate L per second new , the system can adjust the flow rate in real time to ensure the stable operation of the hydraulic project under different conditions. The adjustment process of the adjusted flow rate L per second new is a process of continuous iteration and optimization. By repeatedly adjusting the flow rate and water level parameters, the system can gradually approach the optimal state and maximize the performance of the hydraulic project;

[0133] Adjusted flow rate L per second new will directly affect the next actual current water level W. This cyclic influence forms a closed-loop feedback system, enabling the system to continuously adjust and optimize according to the current state. Specifically, when the adjusted flow rate L per second new increases, the next actual current water level W will also increase accordingly, and vice versa. This cyclic adjustment process helps the system quickly respond to changes and maintain a stable state.

[0134] Refer to Figure 1 As shown, in this implementation plan: Based on the maximum preset flow rate L max and the preset hydraulic efficiency Pa, and when the control center monitors that each monitoring point of the hydraulic project exceeds any one of the preset values of the maximum preset flow rate L max and the preset hydraulic efficiency Pa, a warning is issued.

[0135] In this embodiment, through real-time monitoring, the system can instantly capture abnormal changes in key data such as water level and hydraulic efficiency, thereby quickly triggering the warning mechanism. This instant response ability greatly shortens the time to discover problems and take actions, improves management efficiency, and the real-time monitoring data provides accurate and comprehensive information support to avoid waste and loss of water resources.

[0136] It should be noted that any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall also be within the protection scope of the present invention.
