Description

Technical Field

[0001] This invention relates to the field of water resource scheduling and management technology, and in particular to a method and apparatus for water allocation in complex water supply networks based on design ratios. Background Technology

[0002] Complex network water supply systems typically consist of five basic elements: water source, water conveyance works, water distribution works, water intake works, and water users. These elements form an organic whole through hydraulic connections and topological relationships. Such systems are key engineering measures for achieving cross-regional and cross-basin allocation of water resources, thereby addressing the problem of uneven spatial and temporal distribution of water resources.

[0003] However, existing water supply system scheduling and management methods still have significant limitations when dealing with such complex networks. On the one hand, existing technologies mostly focus on the independent scheduling of a single water source or a single water-using area. When a water shortage occurs in a certain area, the system lacks a global optimization mechanism for dynamic coordination and interconnection of water volume between different areas and different water users. On the other hand, especially when the system includes reservoirs with water storage functions, existing methods lack a standardized process for systematically assessing and reporting water shortage situations at each level. Specifically, how to effectively collect and integrate local water shortage information, taking into account local water supply capacity and the water storage function of reservoirs, from branch lines to main lines, and then to the main lines, and finally transmit it to the headwaters area, has not yet been fully studied and resolved.

[0004] The aforementioned limitations lead to a core challenge: in complex water supply networks with multiple water sources, nodes, users, and storage facilities, it is difficult to achieve fair, efficient, and operable optimized water allocation based on the water rights (i.e., design water volume) of each region.

[0005] There is currently no effective solution to the problem of making precise water diversion scheduling decisions in existing related technologies. Summary of the Invention

Water is allocated in stages according to the actual planned water diversion volume, and a water supply path is determined for each terminal water user.

[0013] According to the present invention, a method for water allocation in a complex water supply network based on a design ratio determines the actual planned water diversion volume from the headwater source node in the next scheduling period based on the total water diversion volume at the headwater.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] This invention provides a method for water allocation in complex water supply networks based on design ratios. Figure 1 This is a flowchart of the water allocation method for complex water supply networks based on design ratios provided by the present invention, such as... Figure 1 As shown, the method includes the following steps: Step S101: Based on the actual water resource supply relationship in the target water supply system, construct a topological relationship model of the complex water network; Step S102: Traverse all end-users in the complex water network, obtain the water demand of the end-users, report and collect the information, and determine the total headwater diversion volume required by the target water supply system. Step S103: Set the headwater diversion decision based on the total water diversion volume of the headwater, and allocate water volume based on the headwater diversion decision.

[0024] In this method, firstly, a topological model of the complex water network is constructed based on the actual water resource supply relationship in the target water supply system, providing a foundation for subsequent analysis and calculation. Then, all end-users in the complex water network are traversed to obtain their water demand, or their water shortage considering local water sources is calculated. The water demand reports of each end-user are collected and aggregated to obtain the total headwater diversion volume required to meet the needs of the entire target water supply system. Finally, based on the total headwater diversion volume, the target water supply system is allocated by a mainframe, determining the final water supply path for each end-user and providing a direct basis for generating scheduling instructions.

[0025] In the aforementioned process, by constructing a topological relationship model and designing a water demand tracing algorithm from downstream to upstream, a standardized and automatically calculated water shortage reporting process was established in a complex water supply network. This method effectively integrates the regulatory role of reservoirs, scientifically determines the actual water shortage in each area, and aggregates information to the water source level by level, providing a precise and unified global perspective for scheduling decisions. Moreover, in the water allocation stage, this method strictly adheres to the design water volume of each water-receiving area as the core allocation basis, achieving a reasonable allocation throughout the entire process from the total water diversion volume to each water-receiving area and then to the downstream water users. This effectively protects the water rights of different areas and water users, makes water resource scheduling work based on evidence, improves the standardization and fairness of management, and solves the problem of difficulty in accurately making water diversion scheduling decisions in existing related technologies.

[0026] Next, based on the designed water volume of each water-receiving area (water-receiving community), the predicted water abundance or scarcity, and the water demand reported by different types of water users, the goal is to achieve a reasonable scheduling of external water sources. The main scheduling content includes constructing a water supply topology diagram of the water-receiving communities, summarizing the water demand reported by the water-receiving communities to the canal head, allocating water volume in the water-receiving communities, and scheduling water supply from the canal head. The specific operation is explained below: In some embodiments, step S101, based on the actual water supply relationship in the target water supply system, constructs a topological relationship model of a complex water network, including: extracting key elements based on the actual water supply relationship in the target water supply system; and constructing a topological relationship model based on the physical connections and hydraulic connections between the key elements.

[0027] Specifically, based on the actual water resource supply relationship in the target water supply system, key elements such as "water source - water conveyance project (channel / pipeline) - node - water user" are extracted. Based on the physical connections and hydraulic relationships between these elements, a directed network topology model that can reflect the characteristics of multiple water sources, multiple nodes, and multiple paths is constructed.

[0028] In this embodiment, the topology of the water supply network for each administrative region is constructed. The connectivity and supply relationships between water sources, irrigation districts, water plants, and regulating reservoirs in the complex water network are analyzed, such as... Figure 2 As shown, Figure 2 This is a topology diagram of a complex water supply system in an embodiment of the present invention. Figure 2 Information on each route is shown in Table 1 below.

[0029] Table 1. Information on Water Supply Lines and Water Demand Reporting

[0030] In some embodiments, step S102 involves information reporting and aggregation to determine the total headwater volume required by the target water supply system. This includes: reporting the water demand of each end-user to the upstream node according to the water supply capacity of the water supply pipeline; repeating the reporting process to form a complete chain starting from all end-users, passing through possible regulating reservoirs and node diversion / convergence, and finally aggregating all water demand to the upstream headwater source node, and determining the total headwater volume required to meet the end-user needs of the target water supply system.

[0031] In this embodiment, the water demand of each end-user is reported to the upstream node according to the water supply capacity of the water supply pipeline. This includes: reporting the water demand of each end-user to the direct upstream node. If the direct upstream node is a regulating reservoir, the maximum supplyable water volume is determined based on the real-time water storage volume and operating rules of the regulating reservoir. The water demand of the end-user is first supplied by the regulating reservoir. The remaining water demand after the regulating reservoir supplies water will continue to be reported to the upstream node of the regulating reservoir. If there are multiple upstream nodes of the regulating reservoir, the remaining water demand will be reported to each upstream node according to the water supply capacity of the water supply pipeline.

[0032] Determine the total headwater volume required to meet the needs of end-users in the target water supply system, including: summarizing the water demand of all end-users to the upstream headwater source node; and determining the total water demand collected at the headwater source node as the total headwater volume required to meet the needs of all end-users in the entire target water supply system.

[0033] In some embodiments, step S103, setting a headwater diversion decision based on the total headwater diversion volume and allocating water based on the headwater diversion decision, includes: determining the actual planned water diversion volume from the headwater source node for the next scheduling period based on the total headwater diversion volume; allocating water volume step by step according to the actual planned water diversion volume, and determining the water supply path for each end user.

[0034] In this embodiment, determining the actual planned water diversion volume from the headwater source node for the next scheduling period based on the total water diversion volume at the headwater includes: comparing and analyzing the water diversion volume at the headwater with the predicted inflow volume at the headwater source node; and determining the actual planned water diversion volume from the headwater source node for the next scheduling period by combining the accuracy of inflow prediction, the engineering water diversion capacity, and the reservoir storage requirements.

[0035] Water is allocated tiered according to the actual planned water diversion volume, and a water supply path is determined for each end-user. This includes: initially allocating the total water diversion volume from the headworks to each receiving area according to the proportion of the designed water volume of each receiving area to the total designed water volume of the target water supply system, thus obtaining the planned allocation volume for each receiving area; then, a more refined secondary allocation is carried out within the receiving area, and the planned allocation volume allocated to the corresponding receiving area is sequentially distributed to each water-using sector (domestic, industrial, agricultural, and reservoir filling) according to the water supply priority of different water-using sectors (domestic, industrial, agricultural, and reservoir filling) within each receiving area; and finally, the final water supply path is determined for each specific end-user based on the topological relationship model.

[0036] For example, based on the predicted abundance or scarcity of water at the headwaters and the water demand reported by each user at the headwaters, the water diversion plan for the next period is determined. Figure 3 As shown, Figure 3 This is a schematic diagram illustrating the allocation of water diversion volume at the canal head in each community under the condition of abundant water inflow (Case 1) in this embodiment of the invention. If the predicted abundant water inflow is 400m³, the water diversion volume at the canal head will be... 3 / s, while the reported total water demand is only 300m³. 3 / s, adhering to the principle of diverting as much water as possible, the next time period will see a water diversion of 300m. 3 / s. For example... Figure 4 As shown, Figure 4 This is a schematic diagram illustrating the allocation of water diversion volume at the canal head in each community under the condition of low water inflow (Case 2) in this embodiment of the invention. If the predicted low water inflow is only 160m³, the water diversion at the canal head will be even lower. 3 / s, while the reported total water demand is only 300m³. 3 The current flow rate of water is insufficient to meet the water demand of users in the next time period. Therefore, a water diversion of 160m³ is planned for the next time period. 3 / s, the specific allocation is shown in Table 2.

[0037] Table 2 Water diversion information for the headwaters node in the next time period under different forecast conditions.

[0038] Then, based on the designed water volume allocation for each water-receiving area (administrative region) and the predicted inflow from the headworks, and according to the predicted abundance or scarcity of water, the inflow for the next period is allocated to each water-receiving area (administrative region) according to the designed water volume. For example... Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram illustrating the allocation of water diversion volume at the canal head to each water user in an embodiment of the present invention where the incoming water is abundant (Case 1). Figure 6 This is a schematic diagram illustrating the allocation of water diversion volume to each water user in a scenario of low water supply (Case 2) according to an embodiment of the present invention. Based on the designed water volume, the average annual water allocation for water-receiving area A is 375 million m³. 3 The average annual water distribution of water-receiving area B is 625 million cubic meters. 3 The designed water volume proportions for the two water-receiving areas are 37.5% and 62.5%, respectively. When the water intake at the headworks is 300m... 3 At a rate of / s, the water-receiving area A receives 100m³ of water from the headwaters. 3 / s, the water-receiving area B receives 200m³ of water from the headworks. 3 / s; when the headworks draw water at 160m 3 At a rate of / s, the water-receiving area A receives 112.5 m³ of water from the headwaters. 3 / s, the water-receiving area B receives 187.5m³ of water from the headworks. 3 / s, at this time, the water demand reported by water-receiving areas A and B is 100m³ respectively. 3 / s and 200m 3 / s, to avoid wasting water resources, the 12.5m of water receiving area A will be diverted. 3 / s is allocated to water-receiving area B. See Table 3 for details.

[0039] Table 3. Water distribution information of water-receiving areas under different water inflow conditions (head section)

[0040] Next, internal adjustments are made within the water-receiving areas (administrative regions). After the water volume is allocated to the water-receiving areas according to the design water volume, internal negotiations and adjustments are carried out in the order of domestic, industrial, irrigation, and reservoir filling. After the adjustments, the allocated water volume for different types of water users in each water-receiving area can be determined, as detailed in Table 4.

[0041] Table 4. Water allocation information for each water user within the water-receiving community.

[0042] Finally, the headwaters and sluice gates are dispatched to supply water according to the water transmission lines and allocated water volumes. Water is also diverted from other areas based on the allocated water volume within the receiving communities and the water demands of individual users, in conjunction with the water supply lines. Information on the water supply lines and the water transport routes is shown in Table 5.

Figure 7 As shown, the device includes: Module 701 is used to construct a topological model of a complex water network based on the actual water resource supply relationship in the target water supply system. The processing module 702 is used to traverse all end-users in the complex water network, obtain the water demand of the end-users, report and collect the information, and determine the total headwater diversion volume required by the target water supply system. The allocation module 703 is used to set the headwater diversion decision based on the total headwater diversion volume and to allocate water volume based on the headwater diversion decision.

[0045] In operation, this device first constructs a topological model of the complex water network based on the actual water supply relationships within the target water supply system, providing a foundation for subsequent analysis and calculations. Then, the processing module 702 iterates through all end-users in the complex water network, obtaining their water demand or calculating their water shortage after considering local water sources. The water demand reports from each end-user are then aggregated to obtain the total headwater intake required to meet the needs of the entire target water supply system. Finally, the allocation module 703 performs mainframe water allocation for the target water supply system based on the total headwater intake, determining the final water supply path for each end-user and providing a direct basis for generating scheduling instructions.

This device effectively integrates the regulating role of reservoirs, scientifically determines the actual water shortage in each area, and aggregates information to the water source level by level, providing a precise and unified global perspective for scheduling decisions. Furthermore, during the water allocation phase, this device strictly adheres to the design water volume of each receiving area as the core allocation basis, achieving a rational allocation from the total water diversion volume to each receiving area and finally to the downstream water users. This effectively protects the water rights of different areas and users, makes water resource scheduling work based on evidence, improves the standardization and fairness of management, and solves the problem of difficulty in accurately making water diversion scheduling decisions in existing related technologies.
