Detailed Description
The present invention is described in detail below with reference to examples, but the present invention is not limited to these examples.
The embodiment of the invention provides a water supply scheduling method based on a parallel reservoir system, which comprises a main water supply reservoir and a water supplementing reservoir, wherein the main water supply reservoir supplies water to a water supply object, and the water supplementing reservoir supplies water to the main water supply reservoir and the water supply object; as shown in fig. 1, the method includes:
s1, determining a plurality of scheduling task areas of a system and scheduling rules of the system in different scheduling task areas according to engineering design parameters of the system;
S2, constructing a total water supply trial calculation model, and calculating to obtain the total water supply according to the total water supply trial calculation model and a scheduling rule;
and S3, obtaining the water supply flow of the main water supply reservoir and the water replenishing reservoir in each scheduling task area according to the total water supply quantity and the total water supply quantity trial calculation model, and performing water supply scheduling according to the water supply flow.
Specifically, the parallel reservoir system includes a plurality of reservoirs, as shown in fig. 2, and the plurality of reservoirs are generally set as main water supply reservoirs or water replenishment reservoirs according to the adjustment performance, the water supply distance, the self-flowing water supply condition and other information of each reservoir, and the main water supply reservoirs and the water replenishment reservoirs can supply water to the water supply objects. When the water supply amount of the main water supply warehouse can meet the requirement of a water supply object, the main water supply warehouse bears the water supply task; when the water supply amount of the main water supply reservoir cannot meet the requirement of a water supply object, the water supply reservoir bears the water supply task.
Notably, in the present invention, as shown in fig. 2, since the water replenishment reservoir may also supply water to the main water supply reservoir, there is a hydraulic connection between the water replenishment reservoir and the main water supply reservoir. When the water supply amount of the main water supply reservoir cannot meet the requirement of the water supply object, the water supply reservoir can supply water to the water supply object and the main water supply reservoir at the same time.
Generally, reservoir water supply scheduling needs to divide a water supply scheduling interval of a reservoir into a plurality of scheduling task areas according to historical data of water level, water supply amount, warehouse-in runoff and the like of the reservoir and the water level of the reservoir, one scheduling decision is set for each scheduling task area, and each scheduling decision has corresponding water supply flow, water supply amount or hydropower station output. The above information is usually visually presented in the form of a water supply schedule. When the water supply system is used for scheduling, the current water level of the reservoir is judged, so that the range of the current scheduling task area of the reservoir can be determined, and further, a scheduling decision corresponding to the scheduling task area can be adopted for water supply scheduling. For example, if the plurality of scheduled task areas are an enlarged water supply area, a guaranteed water supply area, and a limited water supply area, respectively, when the reservoir water levels fall within the three scheduled task areas, the corresponding water supply scheduling decisions are to supply water according to the enlarged water supply amount, to supply water according to the guaranteed water supply amount, and to supply water according to the limited water supply amount, respectively.
However, the existing water supply scheduling method determines relevant parameters of scheduling decisions such as water supply flow, water supply quantity or hydropower station output corresponding to each scheduling task area, such as determination of increasing water supply quantity, guaranteeing water supply quantity and limiting water supply quantity in the above example, which is usually determined by scheduling personnel according to own scheduling experience or is determined through manual repeated checking, so that the scheduling decisions are highly dependent on the experience of the scheduling personnel, are easily influenced by the subjectivity of the scheduling personnel, and the accuracy and checking efficiency of checking results are low. Meanwhile, due to the limitation of manual experience and manual calculation efficiency, the water supply scheduling method cannot fully consider the water demand condition of users, the runoff condition of warehouse entry and the variation fluctuation of reservoir water level in each scheduling task period, and the problems that the reservoir water supply quantity and the actual water demand quantity deviate greatly, the reservoir water supply quantity and the reservoir water supply capacity are not matched and the like are easily caused, so that the reservoir efficiency is wasted or excessively lost are caused. In addition, because the reservoirs in the existing parallel reservoirs are not generally in hydraulic connection, the existing water supply scheduling method needs to independently schedule the reservoirs, so that the complexity of scheduling is increased, precise decision of water supplementing time is difficult, and tight matching among the reservoirs is not facilitated.
In order to solve the problems of the existing water supply scheduling method, the invention optimizes the existing water supply scheduling method to obtain an optimized scheduling scheme. According to the invention, the total water supply trial calculation model is constructed, the error range values of the target total water supply and the target water supply are preset in the model according to the water demand of the water supply object, the water supply flow rates of the main water supply reservoir and the water supplementing reservoir in each scheduling task area in the water supply scheduling period can be accurately obtained, the optimized scheduling scheme is formed by combining a plurality of water supply flow rates, the water supply scheduling is carried out according to the scheme, the fine scheduling can be realized, and the optimal utilization of water resources and reservoir efficiency is realized.
Meanwhile, because the hydraulic connection exists between the main water supply reservoir and the water supplementing reservoir, the scheduling method can respectively obtain the water supply flow of the main water supply reservoir and the water supplementing reservoir in each scheduling task area, and can further obtain the water supply flow of the water supplementing reservoir to the water supply object and the main water supply reservoir, thereby effectively utilizing the water supplementing and accumulating relation between the main water supply reservoir and the water supplementing reservoir, optimizing the water supply sequence and the water supplementing time of the reservoir, and achieving the purposes of fully playing the water accumulating and regulating function of the system and improving the utilization rate of water resources and the system efficiency.
Specifically, the invention does not limit the specific number of main water supply reservoirs and water replenishing reservoirs. The system may include a plurality of main water reservoirs and a plurality of water replenishment reservoirs, where the plurality of water replenishment reservoirs may supply water to one main water reservoir, one water replenishment reservoir may supply water to the plurality of main water reservoirs, and the plurality of water replenishment reservoirs may supply water to a plurality of water supply objects, respectively.
In this embodiment, the main water reservoir is provided with a first pump station for pumping water from the water replenishment reservoir to the main water reservoir; the water replenishing reservoir is provided with a second pump station for pumping water from the water replenishing reservoir to the water supply object.
Correspondingly, the parallel reservoir system of the embodiment comprises a main water supply reservoir, a water supplementing reservoir, a first pump station and a second pump station.
The invention is not limited to the specific number of first and second pump stations. For example, a plurality of first pumping stations and a plurality of second pumping stations may be included in the system.
Specifically, the water supply process of the water replenishing reservoir to the main water supply reservoir and the water supply object is as follows:
When the water supplementing reservoir is required to supply water to the water supply object, the second pump station is started by the water supplementing reservoir, and then the water is pumped from the water supplementing reservoir to the water supply object by the second pump station;
When the water replenishing reservoir is needed to supply water to the main water supply reservoir, the first pump station is started by the main water supply reservoir, and then the first pump station pumps water from the water replenishing reservoir to the main water supply reservoir.
In practice, as shown in fig. 2, the amount of water extracted from the water replenishment reservoir by the second pump station may be the total water supply amount of water supplied to the water supply target and supplied to the main water supply reservoir; at this time, the first pump station can pump water from the water replenishing reservoir to the main water supplying reservoir in the water supplying channel of the water supplying object so as to replenish the water quantity of the main water supplying reservoir.
Specifically, the engineering design parameters of the system include: the system comprises hydrologic data, characteristic water level, characteristic reservoir capacity, water level-reservoir capacity relation curve, tail water level-flow relation curve, comprehensive water demand of users and other information of each reservoir, installed capacity, design flow and other information of each reservoir pump station, design flow of a water supply channel and other information.
It should be noted that, in the present embodiment, the engineering parameters related to time are all long series of data. The water supply flow time series of the main water supply reservoir and the water replenishing reservoir are obtained through calculation according to long-series data, the problems of insufficient representativeness and accuracy of classical annual method and conventional runoff adjustment calculation can be solved, and therefore water supply scheduling decisions can be more in line with actual runoff conditions and actual water demand conditions, and waste of water resources is avoided.
Specifically, in S1, according to engineering design parameters of the system, determining multiple scheduling task areas of the system may be:
obtaining a simulated water supply flow time sequence of the system according to engineering design parameters of the system;
and determining a plurality of scheduling task areas of the system according to the simulated water supply flow time sequence.
Notably, the simulated water supply flow time series includes a main water reservoir simulated water supply flow time series and a make-up water reservoir simulated water supply flow time series.
Specifically, the time sequence of the simulated water supply flow of the system is obtained according to the engineering design parameters of the system, and can be:
constructing a joint scheduling simulation model according to engineering design parameters of the system;
and obtaining a simulated water supply flow time sequence of the system according to the engineering design parameters and the joint scheduling simulation model.
Specifically, the joint scheduling simulation model includes a simulated water supply flow function and a second constraint.
In this embodiment, the expression simulating the water supply flow rate function is specifically:
（1）
In the formula (1), the components are as follows, A water flow required by a water supply object in a period t,And J is the total amount of reservoirs in the system, j=1, 2 and … … J, and is the water supply flow rate of the jth reservoir in the system in the period t.
Notably, the jth reservoir in the system may be the main water reservoir or the make-up reservoir.
Wherein, the water flow required by the water supply object in the t periodCan be directly obtained through engineering design parameters of the system, and a plurality of continuous time periods are obtained from the long-series engineering design parameters. Inputting a plurality of consecutive periods according to formula (1)The water supply flow rates of the main water supply reservoir and the water supplementing reservoir in the continuous period can be respectively obtained through calculationAnd sequentially and continuously arranging and combining a plurality of mutually matched water supply flows of the main water supply reservoir according to the time sequence, namely the time sequence of the simulated water supply flow of the main water supply reservoir, and sequentially and continuously arranging and combining a plurality of mutually matched water supply flows of the water supply reservoir according to the time sequence, namely the time sequence of the simulated water supply flow of the water supply reservoir.
It will be appreciated that, for each particular, according to equation (1)Water supply flow rate of main water supply reservoir and water supplementing reservoir in t periodThere may be multiple values. Further, for a plurality of consecutive periodsThe time series of the simulated water supply flow rates of the multiple groups of main water reservoirs and the time series of the simulated water supply flow rates of the multiple groups of water replenishing reservoirs can be correspondingly obtained.
However, the process is not limited to the above-described process,The value of (2) not only needs to satisfy the functional relation of the formula (1), but also needs to comprehensively consider whether the existing conditions of each engineering facility in the parallel reservoir system can be provided or notWater supply amount corresponding to the value and supplyWhether the water supply amount corresponding to the value can influence the normal operation of each engineering facility in the system or not.
Thus, the present embodiment is based onThe relation between the system and engineering design parameters such as the parameters of a water reservoir, the parameters of a pump station and the like in the system is provided with a second constraint condition, and the system is characterized in thatIs constrained by the value of (2) so that each engineering facility in the parallel reservoir system can provide and connectThe corresponding water supply quantity is valued, and the normal operation of each engineering facility in the system is not influenced after the water supply quantity is supplied.
It will be appreciated that the number of components,The relationship to system engineering design parameters is common knowledge in the art.
Specifically, the second constraint includes:
1. The water balance constraint condition of the reservoir is as follows:
（2）
In the formula (2), the amino acid sequence of the compound, The water storage capacity of the jth reservoir in the period t is obtained; for the j-th reservoir Water storage in the time period; for the storage flow rate of the jth reservoir in the period t, For the delivery flow of the jth reservoir in the period t,Pumping flow of the pump station of the jth reservoir in the period t,The water supply flow rate of the jth reservoir in the period t,Is the duration of the t period.
Notably, since the jth reservoir may be the main water supply reservoir or the water replenishment reservoir, the jth reservoir may be the first or second pump station.
2. Water level constraint conditions:
（3）
In the formula (3), the amino acid sequence of the compound, The water level of the jth reservoir in the period t is set; The lowest water level of the jth reservoir; Is the highest water level of the jth reservoir.
3. Ecological flow constraint conditions:

4. Pump station output constraint conditions:
（5）
In the formula (5), the amino acid sequence of the compound, The pump station of the jth reservoir is powered by the pump station in the period t,Is the installed capacity of the pump station of the jth reservoir.
5. Pump station and water supply channel design flow constraint condition:
（6）
In the formula (6), the amino acid sequence of the compound, Pumping flow of the pump station of the jth reservoir in the period t,For the design flow rate of the pump station of the jth reservoir,For the water supply flow rate of the jth reservoir in the period t,Is the design flow of the water supply channel.
6. Water supply flow error range constraint conditions:
（7）
In the formula (7), the amino acid sequence of the compound, The water flow required by the water supply object in the t period; for the water supply flow rate of the jth reservoir in the period t, J is the total amount of the reservoirs in the system, Is the water supply flow error value.
Wherein,The value of (2) may be preset according to the actual situation,The smaller the value of (2), the total water supply flow of the system in the t periodThe closer to the water demand of the water-requiring object in the t period。
7. All variable value range constraints:
The values of all variables are greater than or equal to 0.
Generally, according to the formula (1) and the second constraint condition, a plurality of groups of main water supply reservoir simulated water supply flow time sequences and a plurality of groups of water replenishing reservoir simulated water supply flow time sequences can be correspondingly obtained, and the closest water supply time sequences can be selectedThe time series of the simulated water supply flow of the main water supply reservoir and the water supplementing reservoir is used as the time series of the simulated water supply flow of the system.
Meanwhile, in the calculation process of the simulated water supply flow function, the simulated data such as the time sequence of reservoir water disposal, the time sequence of reservoir water level and the like can be obtained. It is understood that the information of the water supply amount, the water discard amount, the reservoir water level and the like of the water supply reservoir obtained through the water demand of the water supply object is common knowledge known to the person skilled in the art.
Specifically, determining a plurality of scheduling task areas of the system according to the simulated water supply flow time sequence may be:
determining a scheduling line of the system according to the simulated water supply flow time sequence;
A plurality of scheduled task areas of the system are determined according to the scheduling lines.
Specifically, the dispatching line is a water supplementing starting line; the plurality of scheduled task areas include a water replenishment start area and a water replenishment stop area.
In this embodiment, the dispatch line and the dispatch task area are each determined and divided based on the simulation data of the main supply reservoir.
In this embodiment, as shown in fig. 4, according to the above-mentioned time sequence of the simulated water supply flow of the main water supply reservoir, the year when the water is supplied from the water replenishing reservoir to the main water supply reservoir is obtained, and the lower envelope of the water level value of the main water supply reservoir at each period in the year is the water replenishing start line. When the water level of the main water supply reservoir is lower than the line, the water storage capacity of the main water supply reservoir is insufficient to supply water to the water supply object, and the water supply reservoir is required to supply water to the water supply object and the main water supply reservoir; when the water level of the main water supply reservoir is higher than the line, the water storage capacity of the main water supply reservoir is enough to supply water to the water supply object, and the water supply reservoir is not needed to supply water to the water supply object and the main water supply reservoir.
Therefore, as shown in fig. 4, the present embodiment divides the area between the water replenishment start line and the lowest water line into water replenishment start regions, and divides the area between the water replenishment start line and the highest water line into water replenishment stop regions. In the water supplementing stop zone, the main water supply reservoir supplies water to the water supply object, and the water supplementing reservoir, the first pump station and the second pump station are not started; in the water replenishing starting area, the water replenishing reservoir supplies water to the main water supply reservoir and the water supply object, and the water replenishing reservoir, the first pump station and the second pump station are started.
Through setting up moisturizing start line, can confirm the moisturizing opportunity, and then effectively instruct the water supply dispatch of moisturizing reservoir, avoid water reservoir and water supply object to appear the lack of water condition.
In practice, however, when the water level of the main water supply reservoir fluctuates up and down near the water replenishing start line, the main water supply reservoir, the water replenishing reservoir, the first pump station and the second pump station are all in frequent alternate on-off states, which increases the workload of the dispatcher and is unfavorable for the safe and stable operation of related equipment.
In order to avoid the above situation, as shown in fig. 4, the present embodiment further provides a water replenishment stop line above the water replenishment start line.
Specifically, the plurality of scheduling lines may be plural, and the plurality of scheduling lines includes a water replenishment start line and a water replenishment stop line.
Correspondingly, the plurality of scheduling task areas comprise a water supplementing starting area, a water supplementing buffer area and a water supplementing stopping area.
In this embodiment, the water replenishing start line is raised to a preset water level, and when the water level of the main water supply reservoir is at the preset water level, the water demand of the water supply object in the period of the year can be satisfied, and the water replenishing reservoir is not required to supply water to the water supply object, and the preset water level is the water replenishing stop line.
In practice, the specific position of the preset water level can be set according to the actual condition of the engineering.
It will be appreciated that when the water level of the main water supply reservoir is above the refill stop line, the water storage capacity of the main water supply reservoir is sufficient to supply water to the water supply target without the need for the refill reservoir to supply water to the water supply target and the main water supply reservoir.
Therefore, as shown in fig. 4, the present embodiment divides the area between the water replenishment start line and the lowest water line into water replenishment start areas, divides the area between the water replenishment start line and the water replenishment stop line into water replenishment buffer areas, and divides the area between the water replenishment stop line and the highest water line into water replenishment stop areas.
Specifically, after the water replenishing buffer area is set, the working state of the system is as follows:
When the water level of the main water supply reservoir continuously drops from the water supplementing stop zone to the water supplementing buffer zone, water is still supplied to a water supply object from the main water supply reservoir; when the water level drops to the water replenishing starting area, the main water supply reservoir stops supplying water to the water supply object, and the water replenishing reservoir supplies water to the main water supply reservoir and the water supply object; after the water is supplied from the water replenishing reservoir, the water level of the main water supply reservoir continuously rises, when the water level rises to the water replenishing buffer area, the main water supply reservoir is not started until the water level rises to the water replenishing stop area, and the water replenishing reservoir is started and stops supplying water.
When the water level of the main water supply reservoir continuously falls in the water replenishing buffer zone and falls above the water replenishing starting line, if the main water supply reservoir starts to rise due to the increase of self-warehousing runoff and the like, although the main water supply reservoir is positioned in the water replenishing buffer zone, the water replenishing reservoir is not started, and water is continuously supplied to a water supply object from the main water supply reservoir.
Therefore, when the water replenishing reservoir supplies water to the water supplying reservoir, sufficient water can be supplied to the water supplying reservoir, and the situation that the water level of the water supplying reservoir drops below a water replenishing starting line once the water supplying reservoir stops supplying water is avoided, so that the main water supplying reservoir, the first pump station and the second pump station of the water replenishing reservoir and related equipment are frequently started and stopped.
Specifically, the scheduling rules of the water replenishment start region, the water replenishment buffer region and the water replenishment stop region may be:
when the system is in the water supplementing stop zone, the main water supply warehouse supplies water to the water supply object;
when the system is in the water supplementing buffer zone, the main water supply reservoir and the water supplementing reservoir maintain the current water supply state;
when the system is in the water replenishing starting area, the water replenishing reservoir supplies water to the main water supply reservoir and the water supply object.
Wherein, when the system is in the moisturizing buffer zone, main water supply reservoir and moisturizing reservoir maintain current water supply state, specifically do:
when the system is in the water supplementing buffer zone and the main water supply reservoir is in a water supply state, the main water supply reservoir continuously supplies water to the water supply object;
when the system is in the water supplementing buffer zone and the water supplementing reservoir is in a water supplying state, the water supplementing reservoir continuously supplies water to the main water supplying reservoir and the water supplying object;
in particular, the plurality of scheduling lines may also include a discard line, a tamper line, and a limit supply line.
In particular, the plurality of scheduled task areas may be further divided into a maximum water supply area, an enlarged water supply area, a guaranteed water supply area, and a restricted water supply area.
Specifically, as shown in fig. 3, according to the above-mentioned time sequence of the simulated water supply flow rate of the main water supply reservoir, the year of the water discard situation is obtained, and the upper envelope of the water level value of the main water supply reservoir in each period of the year is the water discard prevention line; acquiring years without water abandoning condition and water supply meeting water demand, wherein an upper envelope line of a water level value of a main water supply reservoir in each period of the year is an anti-damage line; and acquiring a lower envelope line of the water level value of the main water supply reservoir in each period of the year, which is used for limiting the water supply line, wherein the water supply quantity meets the water demand without the water abandoning condition.
Accordingly, as shown in fig. 3, the area between the highest water line and the reject water line is the maximum water supply area, the area between the reject water line and the damage prevention line is the enlarged water supply area, the area between the damage prevention line and the limit water supply line is the guaranteed water supply area, and the area between the limit water supply line and the lowest water line is the limited water supply area.
In this embodiment, the water supply restriction line and the water replenishment start line may coincide, and thus the water supply restriction area may coincide with the water replenishment start area.
In practice, a water supply scheduling diagram can be drawn according to the scheduling line, and a scheduling task area is visually presented, so that engineering technicians can conveniently schedule water supply. After the water supply schedule is drawn, unreasonable water level points such as abnormality, mutation and the like in the schedule are required to be checked and corrected, and the line type of the schedule is appropriately corrected, so that the water supply schedule is reasonable.
In this embodiment, the scheduling rules of the maximum water supply area, the enlarged water supply area, the guaranteed water supply area, and the restricted water supply area may be:
The maximum water supply area, the enlarged water supply area and the guaranteed water supply area are all charged with water supply tasks by the main water supply warehouse; and the water supply area is limited to be overlapped due to the water supplementing start period, so that the water supplementing reservoir bears the water supply task. And setting initial values or initial value taking intervals of parameters such as water supply flow of the main water supply reservoir and the water supplementing reservoir for each scheduling task area respectively to obtain scheduling rules of the system in different scheduling task areas.
Specifically, in the system of the embodiment, in a maximum water supply area, a guaranteed water supply area and a limited water supply area, the initial water supply flow values of the main water supply reservoir which are correspondingly arranged are respectively the design flow of the water delivery channel, the maximum water demand, the average water demand and 0; the initial values of water supply flow of the water supply reservoir which is correspondingly arranged for supplying water to the water supply object are 0, 0 and average water demand.
The average water flow rate refers to the average value of the water flow rates in all the time periods in the scheduling period, and the maximum water flow rate refers to the maximum value of the water flow rates in all the time periods in the scheduling period.
In order to accurately determine the water supply flow of each dispatching task area, reduce the deviation between a dispatching result and a dispatching target and realize refined dispatching, the invention further constructs a total water supply trial model, calculates the total water supply trial model by combining the dispatching rule of each dispatching task area, and can accurately obtain the water supply flow of a main water supply reservoir and a water supplementing reservoir in each dispatching task area in a water supply dispatching period, thereby forming a group of optimized water supply flow. The water supply scheduling is performed according to the optimized water supply flow rate, so that the actual water supply amount is as close to the target water supply amount as possible, and the deviation between the actual water supply amount and the actual water demand amount is reduced.
Specifically, the total water supply trial model includes a total water supply function and a first constraint.
Specifically, the expression of the total water supply amount function is:
（8）
In the formula (8), W is the total water supply amount of the parallel reservoir system in a dispatching period; the water supply flow rate of the jth reservoir in the kth scheduling task area in the t period; t is the total number of time periods in the dispatching period, J is the total amount of reservoirs in the system, Is the duration of the t period; t=1, 2, … … T; j=1, 2, … … J.
In practice, the main water supply reservoir and the water supplementing reservoir can only be in one scheduling task area at the same time within a certain period t, soThe current period t of the program determines which scheduling task area it is currently inThe scheduling task area in which the t period is positioned is determined by the water level of the main water supply reservoir in the t period.
So that the number of the parts to be processed,The value of the (2) needs to consider whether the jth reservoir is a main water supply reservoir or a water supplementing reservoir, and meanwhile, the jth reservoir is judged to be in which scheduling task area according to the time period t, and the value of the (b) needs to be determined according to scheduling rules and design parameters. If the water reservoir is a water replenishing reservoir, the water supply condition of the water reservoir to the main water reservoir and the water supply object is considered, whether the water supply capacity of the water reservoir can meet the water supply quantity corresponding to the value of the water reservoir is judged, and then the value of the water reservoir is correspondingly adjusted.
Thus, to restrictIn the present embodiment, the first constraint condition is set.
Specifically, the first constraint includes:
1. The water balance constraint condition of the reservoir is as follows:
（9）
In the formula (9), the amino acid sequence of the compound, The water storage capacity of the jth reservoir in the period t is obtained; for the j-th reservoir Water storage in the time period; for the storage flow rate of the jth reservoir in the period t, For the delivery flow of the jth reservoir in the period t,Pumping flow of the pump station of the jth reservoir in the period t,The water supply flow rate of the jth reservoir in the period t,Is the duration of the t period.
Notably, since the jth reservoir may be the main water supply reservoir or the water replenishment reservoir, the jth reservoir may be the first or second pump station.
2. Water level constraint conditions:
（10）
In the formula (10), the amino acid sequence of the compound, The water level of the jth reservoir in the period t is set; The lowest water level of the jth reservoir; Is the highest water level of the jth reservoir.
3. Ecological flow constraint conditions:
（11）
in the formula (11), the amino acid sequence of the compound, For the ecological flow of the jth reservoir in the period t,Is the ecological base flow of the j reservoir.
4. Pump station output constraint conditions:
（12）
in the formula (12), the amino acid sequence of the compound, The pump station of the jth reservoir is powered by the pump station in the period t,Is the installed capacity of the pump station of the jth reservoir.
5. Pump station and water supply channel design flow constraint condition:
（13）
in the formula (13), the amino acid sequence of the compound, Pumping flow of the pump station of the jth reservoir in the period t,For the design flow rate of the pump station of the jth reservoir,For the water supply flow rate of the jth reservoir in the period t,Is the design flow of the water supply channel.
6. Supplementing water flow constraint conditions:
（14）
In the formula (14), the amino acid sequence of the compound, In order to supply water to the main water supply reservoir in the period t,And (3) designing pumping flow for the mth first pump station, wherein M is the number of the first pump stations to be started.
7. Water supply range error constraint conditions:
（15）
In the formula (15), W is the total water supply amount of the parallel reservoir system in the dispatching period, For the target total water supply amount,Is the total water supply amount error value.
Wherein,The value of (2) may be preset according to the actual situation,The smaller the value of (2), the closer the total water supply amount W is to the target total water supply amount。
8. All variable value range constraints:
The values of all variables are greater than or equal to 0.
Specifically, in this embodiment, according to the first constraint condition and the scheduling rule, a set of water supply flows of the main water supply reservoir and the water supply reservoir is selectedAnd (3) inputting the group of values into the total water supply function for trial calculation, and repeatedly optimizing and calculating through a trial calculation model to finally obtain the current total water supply W meeting the first constraint condition.
It is easy to understand that the correspondence relationship between each group of water supply flow rate and the total water supply amount W can be established through the operation process of the total water supply amount function.
When the current total water supply amount W is determined according to the foregoing steps, the total water supply amount function may be returned again, and a set of water supply amounts corresponding to the current total water supply amount W may be obtained by searching for the correspondence between the established water supply amounts and the current total water supply amount W. Then, the water supply flow values of the main water supply reservoir and the water supplementing reservoir in each scheduling task period can be respectively extracted from the group of water supply flows, namely, the water supply flows which the main water supply reservoir and the water supplementing reservoir should take in each scheduling task area can be definitely determined, a scheduling scheme is formed, and further, the water supply scheduling work of the water supply reservoir and the water supplementing reservoir can be reasonably guided.
Specifically, the water supply flow of the water replenishing reservoir can be further divided into the water supply flow of the water replenishing reservoir to the main water supply reservoir and the water supply flow of the water supply object, so that the water supply scheduling work of the water replenishing reservoir can be guided more reasonably and clearly.
Specifically, before each trial calculation, the water supply flow of the main water supply reservoir and the water supplementing reservoir is required to be controlled according to the first constraint condition and the scheduling ruleAnd (5) taking a value. In general terms, the process is carried out,Can take a value between 0 and the design flow of the water delivery channel and combine the scheduling rule pairIs repeatedly optimized due to the value ofThe value range of the method is larger, so that the trial calculation times are more, and the calculation efficiency is affected. In practice, therefore, it is necessary to set a scheduling control flow preliminarily matching the scheduling target for each scheduling task area in combination with the scheduling experience and the actual situation, and give the scheduling control flow toThe initial value is given, and the value can be firstly taken around the vicinity of the scheduling control flow and calculated in an trial mode during model calculation, so that the model can be helped to obtain a result quickly, the trial calculation times are reduced effectively, and the calculation efficiency is improved.
Specifically, before the total water supply amount is calculated, the method may further include:
and initializing a total water supply trial calculation model.
Specifically, the initialization is to supply water flow rate in the function of total water supplyA set of initial values is given, which can be set according to the scheduling rules and combining scheduling experience and actual conditions.
The embodiment sets a scheduling control flow for each scheduling task area, wherein the maximum water supply area, the enlarged water supply area and the guaranteed water supply area bear water supply tasks by a main water supply warehouse, and the scheduling control flow is respectively a design flow of a water delivery channel, a maximum water demand flow and an average water demand flow; the water supply area is limited to bear the water supply task by the water replenishing reservoir, and the flow is scheduled and controlled to be the average water demand.
The present embodiment assigns the scheduling control flow rate of each scheduling task section as an initial value to the water supply flow rate in the total water supply amount functionThe model is initialized to complete the water supply trial calculation, so that the purpose of improving the model calculation efficiency is achieved. Specifically, before S1, the method may further include:

In practice, the water supply is started without the need of the water replenishing reservoir in the period of larger water storage capacity of the main water supply reservoir such as the flood season.

In the following, this embodiment takes the water diversion project of Shaanxi Hanji of Han dynasty across the river basin as an example, and specifically describes the effectiveness and rationality of the water supply scheduling method based on the parallel reservoir system.
The water diversion project of the cross-river basin of the Han dynasty is a 'North Water diversion project' of Shaanxi province, and the project is generally arranged as follows: the golden gorge water junction is built on the main river of the Han river, the three-river mouth water junction is built on the branch meridian river, water is transferred to the middle region of the Wei river basin through the water transfer tunnel from the north shore of the Han river to the north foot of the Qinling river, and then the water transfer branch lines are distributed to all water objects, so that the contradiction between supply and demand of water resources is relieved. The overall layout of the project is shown in fig. 6, and the characteristic parameters of each reservoir and pump station in the project are shown in table 1.
TABLE 1 characteristic parameters of water diversion engineering for Wei cross-basin
Currently, the target water supply for initial operation of the water-diversion-Chinese-medicine-Wei-engineering is 5 hundred million cubic meters. In order to better meet the target water supply, the embodiment forms a parallel reservoir system by combining the golden gorge reservoir, the three-river reservoir and a plurality of pump stations of the two reservoirs, and performs joint scheduling on the three-river reservoir and the golden gorge reservoir. The system takes the three-river water reservoir as a main water supply reservoir and takes the gold gorge reservoir as a water supplementing reservoir, the three-river water reservoir utilizes the regulating performance of the three-river water reservoir to bear the main water supply task, and the gold gorge reservoir bears the water supplementing task in the dead water period, so that the achievement of the initial water supply target is fully ensured.
According to the method, according to the runoff data and the second constraint condition of the three-estuary reservoir and the golden gorge reservoir under the month scale of 7 months in 1954 to 6 months in 2021, a self-iterative simulation algorithm is adopted to solve a simulated water supply flow function, and a simulated water supply flow time sequence of the three-estuary reservoir and the golden gorge reservoir is obtained.
According to the above simulated water supply flow time sequence, the present example determines a plurality of scheduling task areas of the system and scheduling rules of the system in different scheduling task areas, and performs appropriate correction and rationality verification, so as to draw a three-river water reservoir water supply scheduling partition map as shown in fig. 7 and 8. Meanwhile, initial water supply flow values of all scheduling task areas from top to bottom in the scheduling diagram are preliminarily determined, and the initial water supply flow values are respectively a Qinling mountain tunnel design flow, a water flow required maximum value and a water flow required average value. Then, according to the number of pump stations and the design flow of each pump station, two different working conditions when the system is in the water supplementing state can be obtained, and the number of pump stations under the two working conditions is shown in table 2.
Table 2 two different conditions when the system is in the water make-up state
As can be seen from Table 1, the installed number of pump stations in the golden gorge reservoir is 7, and the installed number is set according to the designed water supply amount of the golden gorge reservoir. However, since the present example is an initial operation, the target water supply amount thereof is far smaller than the designed water supply amount of the reservoir, the number of open stages of the initial operation is set to 2 or 3 in table 2.
In actual operation of this example, the gold gorge reservoir supplies water to the water supply subject and the main water supply reservoir is pumped by the gold gorge pump station, and the tri-gate pump station pumps a portion of the water from the total amount for supplementing the water storage capacity of the tri-gate reservoir. Therefore, the water supply flow of the golden gorge reservoir to the water supply object is the water pumping flow of the golden gorge pump station minus the water supply flow of the three-estuary reservoir. The two working conditions are calculated respectively, and corresponding numerical values in table 2 can be obtained.
In this example, the above-mentioned dispatch control flow rate of each dispatch task area is input as an initial value into the total water supply function, and according to the dispatch rule and the above-mentioned two working conditions, the water supply flow rates of the three estuary reservoirs and the golden gorge reservoir in each dispatch task area can be calculated and obtained as shown in table 3.
TABLE 3 Water supply control flow for each scheduled task area
Specifically, according to the water supply control flow rate of each scheduling task area in table 3, it can be determined that the water supply scheduling scheme of the three-estuary reservoir is as follows:
(1) In the maximum water supply area, the water level of the single water reservoir of the three-river water reservoir approaches the highest water level, and water is supplied according to the water supply flow of 70m 3/s in order to ensure the safety of the water reservoir and avoid water abandoning; in the enlarged water supply area, the water is supplied to a single reservoir of a three-estuary reservoir, the water is supplied to the enlarged water storage bias, and the water is supplied according to the flow of not less than 17m 3/s; the water supply area is ensured, the water is supplied to a single water warehouse of the three-river water warehouse, the normal water demand is ensured, and the water is supplied according to the flow of not less than 14m 3/s.
(2) In the limited water supply area, the three-river water reservoir cannot ensure normal water supply, and the golden gorge reservoir supplies water to the water supply object, and simultaneously supplies water to the three-river water reservoir to supplement the water quantity of the three-river reservoir. According to the embodiment, two different working conditions of water supplementing states are set according to the water inlet and water level conditions of the golden gorge reservoir, water can be supplied to the three-river water reservoir according to the flow of 18m 3/s or 9m 3/s, and water can be supplied to a water supply object according to the flow of 17m 3/s or 14m 3/s.
After water supply scheduling is carried out according to the scheme, the annual average water supply amount of the parallel reservoir system is 5.03 hundred million cubic meters, wherein the three-river water reservoir supplies 4.93 hundred million cubic meters to a water supply object, and the golden gorge reservoir supplies 0.10 hundred million cubic meters to the water supply object. The total water supply is very close to the water supply target of 5 hundred million cubic meters running in the initial stage of the water supply engineering, and the high-efficiency utilization of water resources is realized.
Further, after the water supply scheduling is performed according to the water supply scheduling scheme, the actual water supply flow time sequence of the three-river water reservoir shown in fig. 9 and the actual water supply flow time sequence of the golden gorge reservoir shown in fig. 10 can be obtained.
As can be seen from fig. 9 and 10, when the water supply scheme is adopted for scheduling, the three-river water reservoir exerts its many years of regulation performance, stores incoming water in the rich water period, the water level continuously rises to the highest water level, continuously supplies water in the dry water period, the water level drops to the limited water supply line, and the reservoir water level shows regular change of rich water and full water in the annual year, and the operation is relatively stable. Meanwhile, the water supply process is changed along with the water supply object demand, and the water supply quantity is high in matching degree with the water demand.
In the dry period, the water level of the three-river mouth rises to the normal condition faster under the following water filling and water supplementing effects of the golden gorge reservoir, so that the regulation capability of the three-river mouth reservoir is enhanced. The water supply period of the golden gorge reservoir is highly synchronous with the water shortage period of the three-estuary reservoir, and the fluctuation of the water supply quantity of the golden gorge reservoir and the three-estuary reservoir are highly matched, so that the method can realize accurate and timely water supplementing, and the overall dispatching operation of the system is more stable.
While the application has been described in terms of preferred embodiments, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the scope of the application, and it is intended that the application is not limited to the specific embodiments disclosed.
