Description

Technical Field

[0001] The present application relates to the technical field of water resource scheduling, and in particular to a multi-water source automatic control method and system. Background Art

[0002] Water resources are the material basis for human survival and economic and social development. With the continuous increase in water supply demand, people have higher requirements for the rational allocation of water resources. In the process of water resource allocation, a water point will draw water from at least one water source, and the water storage capacity of each water source is constantly changing. In order to ensure that each water point can obtain the required water resources, it is necessary to control the water source of the water point.

[0003] At present, the patent application document with application publication number CN116822877A discloses a water resource allocation method, device and medium based on knowledge graph, wherein the method includes: associating the relationship between multiple water conservancy objects corresponding to the pre-acquired water resources to generate a water conservancy supply and demand knowledge graph, where the water conservancy objects include water use areas and water sources; obtaining the historical water use data and pre-generated planned water use data of each water use area, and generating the area water use forecast data of each water use area based on the historical water use data and the planned water use data; obtaining the historical path of the water source of each water source Flow data, predict the runoff of each water source according to the historical runoff data of the water source, and generate water volume forecast data for each water source; obtain the water flow data of each water source and the real-time water quality monitoring data of the upstream of the water source, and determine the water quality forecast data of each water source according to the water flow data of the water source and the real-time water quality monitoring data of the upstream of the water source; according to the water conservancy supply and demand knowledge map, associate the area water use forecast data of each water use area, the water volume forecast data of each water source and the water quality forecast data of each water source to generate a multi-water source water allocation plan.

[0004] The above method generates a multi-source water allocation plan based on the district water consumption forecast data, the water volume forecast data of the water source, and the water quality forecast data of the water source. However, it ignores the impact of the change rate of district water consumption and water volume at the water source on water resource scheduling, resulting in the situation where the water volume of a certain water source is insufficient to meet the district water consumption, resulting in a large water supply pressure on the water source. Summary of the invention

[0005] In order to solve the technical problem of high water supply pressure at water sources, the present application provides a multi-water source automatic control method and system, which can comprehensively consider the water storage change rate of each water source and the water consumption change rate of each water use point, and achieve water supply pressure balancing of multiple water sources.

[0006] In a first aspect, the present application provides a multi-water source automatic control method, the control method comprising: calculating the water storage capacity change rate of each water source and the water consumption change rate of each water point; calculating the water supply pressure of each water source, the water source Water supply pressure for: , For water source The rate of change of water storage capacity, is the number of water use points, For water point of water consumption, For water supply points in water supply scheme From the water source The amount of water taken, For water point In response to the water supply pressure of any water source being greater than a pressure threshold, or the variance of the water supply pressure being less than a variance threshold, adjusting the water supply scheme, including: calculating the water supply cost between any water use point and each water source, wherein the water supply cost is positively correlated with the length of the water supply path from the water use point to the water source; calculating a target value of the water supply scheme, wherein the target value is equal to the sum of the product of the water intake in the water supply scheme and the corresponding water supply cost, plus the variance of the water supply pressure of each water source; adjusting the water supply scheme multiple times, and controlling the water intake of the water use point from each water source according to the water supply scheme corresponding to the minimum target value.

[0007] Since the water consumption of each water point and the water storage capacity of each water source are constantly changing, the water storage capacity change rate of each water source and the water consumption change rate of each water point are calculated, and then the water supply pressure of each water source in the water supply plan is calculated; in response to the water supply pressure of any water source being greater than the pressure threshold, or the variance of the water supply pressure being less than the variance threshold, the water supply plan is adjusted to achieve the balance of the water supply pressure of multiple water sources. Furthermore, in the process of adjusting the water supply plan, the target value of the water supply plan is calculated, which is equal to the sum of the product of the water intake in the water supply plan and the corresponding water supply cost, plus the variance of the water supply pressure of each water source, and the water supply effect can be evaluated from two aspects: the balance of water supply pressure and the cost of water resource scheduling; the water supply plan is adjusted multiple times, and the water intake of each water point from each water source is controlled according to the corresponding water supply plan when the target value takes the minimum value, so as to achieve the reasonable scheduling of water resources.

[0015] Water resources are dispatched along the water supply path between the water use point and the water source. Water resources are dispatched from the water source to the water use point through various transportation methods such as horizontal transportation, lifting to high places, and lowering to low places by water supply pumps. Therefore, the water supply path is divided into multiple path segments, and the water supply cost is accurately calculated based on the slope of the fitted straight line in each path segment.

[0017] , is the number of path segments, For path segment The slope of the fitted line, For path segment Length, is a symbolic function.

[0018] For a path segment, when the slope of the fitted line is greater than 0, it means that the path segment is on an upward trend, and the cost of water resource scheduling on this path segment is high; when the slope of the fitted line is less than 0, it means that the path segment is on a downward trend, and the cost of water resource scheduling on this path segment is low. Therefore, the more path segments with a slope of the fitted line greater than 0, the higher the water use point. With water source The greater the cost of water supply.

[0021] For a path segment, the larger the slope of the fitted straight line is, the faster the elevation value in the path segment rises, and the higher the cost of water resource scheduling on the path segment is. Therefore, in calculating the water supply cost, when the path segment The slope When it is less than 0, The value is 0; when the path segment The slope When greater than 0, The , able to preserve path segments The slope of the water supply can improve the accuracy of the water supply cost.

[0034] According to the first aspect of the present application, the present application provides a multi-water source automatic control method for controlling the amount of water taken from each water source at a water use point. The water sources may be different river basins or different tap water plants.

[0035] Figure 1 FIG. 1 is a flow chart of a multi-water source automatic control method according to an embodiment of the present application. Figure 1 As shown, the multi-water source automatic control method includes steps S101 to S103, which are described in detail below.

[0036] S101, calculating the water storage change rate of each water source and the water consumption change rate of each water use point.

[0037] In one embodiment, when the water source is from different river basins, the water storage capacity of the water source is affected by rainfall or geographical location, and the water storage capacity of the water source at different times is constantly changing; when the water source is from different tap water plants, the water storage capacity of the water source is affected by water production cost or water production efficiency, and the water storage capacity of the water source at different times is also constantly changing; therefore, by comparing the water storage capacity of any water source at different times, the water storage capacity change rate of the water source can be obtained.

[0038] Specifically, water collection Water storage capacity and water sources at various historical moments The rate of change of water storage for: ; and is a set of water storage pairs, respectively, water source In historical moment and historical moments water storage capacity; Indicates water source The satisfaction of obtaining All water storage pairs of is the mean value function.

[0039] Among them, multiple historical moments are 10 moments before the current moment, water source The rate of change of water storage Can reflect the current moment, water source Changes in water storage capacity; When The water storage capacity remains stable; when When The water storage capacity is increasing; When The water storage capacity is showing a downward trend.

[0040] In one embodiment, water collection points Water consumption and water use points at multiple historical moments The change rate of water consumption for: ; and is a set of water consumption pairs, which are water use points In historical moment and historical moments water consumption; Indicates water point The satisfaction of obtaining All water consumption pairs is the mean value function.

[0041] In this way, the water storage capacity change rate of each water source and the water consumption change rate of each water use point are obtained, which can reflect the changes in the water storage capacity of the water source and the changes in the water consumption of the water use point.

[0042] S102, calculating the water supply pressure of each water source.

[0043] In one embodiment, the water supply plan includes the amount of water taken from each water source at any water point; if the water point Only from water source Take water from the water point The change rate of water consumption is greater than that of water source When the water storage capacity change rate is The water storage capacity is not enough to meet the water demand Water consumption, water source The water supply pressure is higher; on the contrary, when the water point The water consumption change rate is less than or equal to the water source When the water storage capacity change rate is The water storage capacity is sufficient to meet the water needs of Water consumption, water source The water supply pressure is low.

[0044] Specifically, water sources Water supply pressure for: , For water source The rate of change of water storage capacity, is the number of water use points, For water point of water consumption, For water supply points in water supply scheme From the water source The amount of water taken, For water point The rate of change of water consumption.

[0045] Among them, water points Water can be drawn from multiple sources. Indicates water point From the water source The proportion of water intake to water volume at the water point can reflect the water use point The change rate of water consumption has an impact on water sources The impact of water supply pressure is the comprehensive change rate of water consumption at all water points, as well as the impact of water points on water sources. The impact of water supply pressure and accurate quantification of water sources water supply pressure.

[0046] For example, see Figure 2 , is the water source calculated according to the embodiment of the present application Schematic diagram of water supply pressure. In the water supply scheme, water point 1 and water point 2 are supplied from the water source. Water is taken from 2 and 3 tons respectively; among them, water point 2 except water source In addition, water If 1 ton of water is taken from a place, then the water source Water supply pressure ,in, and They are the water consumption change rate of water point 1, the water consumption change rate of water point 2 and the water source The rate of change of water storage capacity.

[0047] In this way, the water supply pressure of each water source can be calculated according to the amount of water taken from each water source by any water use point in the water supply plan.

[0048] S103: In response to the water supply pressure of any water source being greater than a pressure threshold, or the variance of the water supply pressure being less than a variance threshold, adjusting the water supply plan.

[0049] In one embodiment, when the water supply pressure of any water source is greater than the pressure threshold, it means that the water storage capacity change rate of the water source cannot meet the water demand of the water point, and the water supply plan needs to be adjusted to change the correspondence between the water point and the water source to reduce the water supply pressure of the water source. Among them, the pressure threshold is 1. Similarly, when the variance of the water supply pressure of all water sources is less than the variance threshold, it means that the difference in water supply pressure between the water sources is large, and the water supply pressure of each water source cannot be balanced. At this time, the water supply plan still needs to be adjusted to change the correspondence between the water point and the water source so that the water supply pressure of each water source tends to be consistent.

[0050] In one embodiment, Figure 3 Flow chart of adjusting the water supply scheme according to an embodiment of the present application. Figure 3 As shown, the water supply adjustment scheme includes steps S201 to S203, which are described in detail below.

[0051] S201, calculating the water supply cost between any water use point and each water source, wherein the water supply cost is positively correlated with the length of the water supply path from the water use point to the water source.

[0052] Among them, the cost of dispatching water resources from any water source to different water use points is different, that is, the water supply cost between any water use point and different water sources is different; if the length of the water supply path from the water use point to the water source is longer, the water supply cost of dispatching water resources from the water source to the water use point will be greater, so the water supply cost is positively correlated with the length of the water supply path from the water use point to the water source. With water source The water supply cost is equal to the water point With water source The length of the water supply path.

[0053] In another embodiment, water resources are dispatched along the water supply path between the water point and the water source, and the water resources are dispatched from the water source to the water point by various transportation methods such as horizontal, lifting to a high place, and lowering to a low place through a water supply pump. It can be understood that the process of lifting to a high place needs to overcome the gravitational potential energy of the water resources, and the energy consumed is much greater than other transportation methods, which leads to a higher cost for water resource dispatch. Therefore, the elevation value of each location point between the water point and the water source will also affect the water supply cost.

[0054] Specifically, water points With water source The calculation method of water supply cost includes: With water source The elevation values ​​of each position point between the paths are taken as the elevation value sequence; the class diameter of the path segment is defined, and the path segment Class diameter for: , and Path segments The starting and ending points of For location point The elevation value of For path segment The fitting straight line of express To the fitting line The fitting straight line is obtained by the least square method; the sum of the class diameters of each path segment is taken as the loss function value, and the elevation value sequence is clustered in an ordered manner to obtain multiple path segments corresponding to the minimum loss function value; the lengths of the multiple path segments are weighted and summed according to the slope of the fitting straight line to obtain the water supply cost.

[0055] Among them, the elevation value is the water point With water source The altitude of the water supply pipeline at the corresponding location.

[0056] Among them, the class diameter The smaller it is, the more accurate the path segment is calculated using the least squares method. When fitting the elevation values ​​in, the better the fitting error, the better the path segment The change trend of the elevation values ​​of each location point in the sequence is the same. Ordered sample clustering can continuously find the optimal segmentation point in the elevation value sequence, thereby dividing all the location points between the water use point and the water source into multiple path segments. First, find the first optimal segmentation point in the elevation value sequence, and divide the time series data into two path segments. Further, on the basis of the two path segments, find the second optimal segmentation point, and divide the elevation value sequence into three path segments. And so on, according to the corresponding division result when the loss function value takes the minimum value, multiple path segments are obtained. The slope of the fitting straight line in a path segment can accurately reflect the change trend of the elevation values ​​of each location point in the path segment.

[0057] In one embodiment, for a path segment, when the slope of the fitted straight line is greater than 0, it means that the path segment is on an upward trend, and the cost of water resource scheduling on the path segment is high; when the slope of the fitted straight line is less than 0, it means that the path segment is on a downward trend, and the cost of water resource scheduling on the path segment is low. Therefore, the more path segments with a slope of the fitted straight line greater than 0, the higher the water use point. With water source The greater the cost of water supply.

[0058] Specifically, water points With water source The cost of water supply for:

[0059] , is the number of path segments, For path segment The slope of the fitted line, For path segment Length, is a symbolic function. hour, ;when hour, ;when hour, .

[0060] Understandably, water points With water source The more the path segments with an upward trend, the more With water source The higher the cost of completing water resource scheduling in a short period of time, the higher the water supply cost. The larger the value of .

[0061] In another embodiment, for a path segment, the larger the slope of the fitted straight line is, the faster the elevation value in the path segment rises, and the higher the cost of water resource scheduling on the path segment is. Therefore, the fitted straight line includes a slope and an intercept; With water source The cost of water supply for: , is the number of path segments, For path segment The slope of the fitted line, For path segment Length, is the ReLU activation function.

[0062] Among them, when the path segment The slope When it is less than 0, it means that the path segment The water resources are lowered to the lower place. In the process of water resource dispatching, there is no need to overcome the gravitational potential energy of water resources, and the cost of water resource dispatching will not be increased. Therefore, when calculating the water supply cost, The value of is 0; on the contrary, in the process of water resource dispatching, it is necessary to overcome the gravitational potential energy of water resources, which increases the cost of water resource dispatching. Therefore, when calculating the water supply cost, The value of .

[0063] Understandably, the path segment Length Equal to path segment The number of position points in For water point With water source The length of the water supply path, Treat as path segment The weight of .

[0064] In this way, the water supply cost between any water use point and any water source can be accurately quantified. The greater the water supply cost between the water use point and the water source, the higher the cost for the water use point to draw water from the water source.

[0065] S202, calculating a target value of the water supply scheme, where the target value is equal to the sum of the product of the water intake and the corresponding water supply cost in the water supply scheme plus the variance of the water supply pressure of each water source.

[0066] The target value is used to reflect the water resource scheduling effect of the adjusted water supply plan. for: , For water source The water supply pressure, is the number of water sources, is the variance of water supply pressure of all water sources, is the number of water use points, For water supply points in water supply scheme From the water source The amount of water taken, For water point With water source The cost of water supply between.

[0067] Understandably, It is used to reflect the difference in water supply pressure among water sources in the water supply plan. The smaller the value, the more balanced the water supply pressure of the water sources is, and the better the water resources scheduling effect is. It is used to reflect the total water supply cost of water resource scheduling in the water supply plan. The smaller the value, the smaller the total water supply cost, the lower the cost of water resource scheduling, and the better the water resource scheduling effect.

[0068] S203, adjusting the water supply plan multiple times, and controlling the amount of water taken from each water source at the water use point according to the water supply plan corresponding to the minimum target value.

[0069] Among them, the optimization algorithm is used to adjust the water intake of any water use point from each water source in the water supply plan, and the water supply plan corresponding to the minimum target value is used as the target water supply plan. At this time, the scheduling effect of water resources corresponding to the target water supply plan is optimal, and the water intake of the water use point from each water source is controlled according to the target water supply plan, realizing the automatic control of multiple water sources in the water resources scheduling process.

[0070] The optimization algorithm is an existing optimization algorithm such as gradient descent method, genetic algorithm or particle swarm algorithm.

[0071] The technical principle and implementation details of the multi-water source automatic control method of the present application are introduced above through specific embodiments. Since the water consumption of each water point and the water storage capacity of each water source are constantly changing, the water storage capacity change rate of each water source and the water consumption change rate of each water point are calculated, and then the water supply pressure of each water source in the water supply scheme is calculated; in response to the water supply pressure of any water source being greater than the pressure threshold, or the variance of the water supply pressure being less than the variance threshold, the water supply scheme is adjusted to achieve the balance of the water supply pressure of multiple water sources. Furthermore, in the process of adjusting the water supply scheme, the target value of the water supply scheme is calculated, which is equal to the sum of the product of the water intake in the water supply scheme and the corresponding water supply cost, plus the variance of the water supply pressure of each water source, and the water supply effect can be evaluated from two aspects: the balance of water supply pressure and the cost of water resource scheduling; the water supply scheme is adjusted multiple times, and the corresponding water supply scheme when the target value takes the minimum value controls the water intake of each water point from each water source to achieve reasonable scheduling of water resources.
