Description
Technical field
The invention belongs to utilization of flood resources technical fields, and in particular to a kind of step reservoir flood based on storage capacity penalty method
Resource utilization method.
Background technology
Flood itself is a kind of natural phenomena, if causes disaster other than the natural quality of flood, largely
Further depend on the intensity and mode of mankind's activity.That is, not all flood can all cause disaster, when the amount of flood
When grade is also less than certain critical value, it is exactly a kind of resource, and by a series of measures, flood can be converted into water resource,
Here it is utilization of flood resources.Currently, the widely used utilization of flood resources method of reservoir mainly has following a few classes：
(1) flood end retains big vast tail method.Reservoir in the super flood season limit level water storage of flood recession flood retention, allow storage capacity according to
Ability determination is let out under reservoir, it is believed that reservoir, which can be disappeared water level using the phase between flood of having a rest, drops down onto flood season limit level, so as to by flood of having a rest
Between the phase instead release can surpass water storage level.Its practical difficulties is the generation moment of end flood and magnitude cannot accurately predict in advance, because
And super storage utilization will bring certain risk, the excessively high risk that can increase next flood Flood Control Dispatch of impounded water levels, impounded water levels
Too low can reduce blocks the economic benefit that tail scheduling generates.
(2) static flood season limit level by stages.Many reservoirs are controlled by stages using flood season limit level, original major flood season one is divided are
Two or one dividing into three, each phase uses different flood season limit levels, is conducive to utilization of flood resources scheduling and the reservoir economy of reservoir in this way
The performance of benefit.But it does not consider forecast information, belongs to traditional " static cost control " mode, and improve flood control to a certain extent
Risk.
(3) flood control operation of reservoir mode is used, flood season limit level is suitably raised.Flood control operation of reservoir mode selects
" the accumulation effective precipitation " of Runoff Production Forecast or " crest discharge " of forecasting or the in short-term previous informations such as " weather " forecast information work
To judge that reservoir meets with the magnitude of flood, the judge index of change vent flow, flood is made to reach in advance uniformly by dam safety evaluation
Aerial drainage improves flood water resources utilization rate.But which is to the stability of flood forecasting scheme precision and automatic Hydrological Telemetry System
It is required that high, operability is possible to be affected.
(4) dynamic control of limitation level in flood season method.According to reservoir characteristic, flood season historical flood and watermark protocol forecast information precision
Etc. data it is for statistical analysis, determine reservoir in flood period dynamic control of limitation level in flood season domain.In application, forecast according to real-time watermark protocol,
Reservoir level is dynamically control in the control domain.Pre- storage is divided into when specific operation to let out method in advance and let out the method for recharging in advance.Basic thought
It is to have much flood carrying capacities just float flood season limit level how much in flood leading time, this is to consider flood and rainfall forecast information
Utilization of flood resources method.But current achievement in research is only conceived to single reservoir, does not consider the storage capacity between multi-reservoir
Compensation relationship.
Invention content
For the deficiency of current existing utilization of flood resources technology, the present invention proposes a kind of step water based on storage capacity penalty method
Library flood-water resources utilization method.Its object is to be often less than flood by using the flood season level of other reservoirs in step reservoir
The characteristics of place value of restricting water supply, considers to carry under storage capacity compensation condition using the part storage capacity of the water level to flood season limit level as compensation storage capacity
Height increases flood-water resources utilization rate by the flood season limit level of compensation reservoir.
Step reservoir flood-water resources utilization method based on storage capacity penalty method, for other reservoirs in Cascade Reservoirs
Starting-point detection is flood season limit level, and purpose reservoir is determined by manner of forecast operation or to the flood routing of seasonal design flood
Dynamic control of limitation level in flood season domain or flood regulation by level and stages value, and actually the flood season level of other reservoirs is often less than in multi-reservoir
The characteristics of flood season limit level value, the part storage capacity of the water level to flood season limit level actually plays compensating action, by considering that storage capacity is mended
Under the conditions of repaying, improving by the flood season limit level of compensation reservoir, step reservoir flood-water resources utilization is achieved the purpose that with this.
The specific technical solution of the present invention is as follows：
A kind of step reservoir flood-water resources utilization method based on storage capacity penalty method, includes the following steps：
1) storage capacity more than needed of upper pond is calculated；
2) the water level operating status of lower reservoir is determined according to the water level operating status of upper pond；
3) flood-water resources utilization is realized by the compensation relationship of storage capacity between step reservoir.
Further, the storage capacity more than needed of the step 1) upper pond is：
Δ V=V (ZA, limit)-V(ZA, 0)
In formula, Δ V is storage capacity more than needed；ZA, limit、ZA,0Respectively upper pond limit of flood-season water level and present situation water storage level；V
() is the function that storage capacity is calculated by water level of upper pond.
Further, the water level of lower reservoir described in step 2) using lower library rise the stage reservoir inflow reduce, by flood
Restrict water supply position raising.
Further, the flood season limit level value of lower reservoir water level described in step 2) is：
Z′B, 0=Z (V (ZB, 0)+ΔV)
In formula, V () indicates to calculate the function of storage capacity by water level, and Z () indicates to calculate the function of water level by storage capacity.From public affairs
Formula is found out, if keeping runoff reach constant, how many storage capacity more than needed of upper library, so that it may which the flood season limit level lifting in lower library is more
Few water
Further, total storage capacity of Cascade Reservoirs described in step 3) is constant.
(1) the Restricted Water Level basic principle based on multi-reservoir flood compensative dispatching.
Why reservoir can undertake flood control task and flood of regulating and storing, and be because reservoir is typically provided with storage capacity and adjusts flood
Storage capacity.In reservoir planning and designing, the storage capacity and reservoir capacity for flood control of reservoir are counted from flood season limit level, that is, control flood Gao Shui
Storage capacity between position and flood season limit level is storage capacity, and the storage capacity between design flood level and flood season limit level is reservoir capacity for flood control.
The reservoir operation phase, since rainfall is in the inhomogeneities of Area distribution, the water storage state of the multi-reservoir of large watershed often have compared with
Big variation, before flood arriving, the flood season water storage level of each reservoir tends not to all reach flood season limit level simultaneously in multi-reservoir, water
Storage capacity when library group total practical storage capacity and reservoir capacity for flood control are commonly greater than planning and designing and reservoir capacity for flood control.Therefore, exist
In reservoir operation, storage capacity can be compensated to excavate this part potentiality by consideration, dynamically raise flood season limit level.
The storage capacity compensation of Fig. 1 visual representations improves the principle of lower library flood season limit level：QA,in(t)、QA,out(t)、QA,out’(t)
Indicate the design flood process of upper library A, the outbound process under design scheduling rule respectively and for downstream reservation storage capacity after
Outbound process.QB,in(t)、QB,in’(t)、QB,out(t) the design flood process of lower library B is indicated respectively, utilizes upper library compensation adjustment
Storage process and design scheduling rule under outbound process.
Flood comes temporarily, and upper library A using the storage capacity Δ V that has more than needed, reduces the storage outflow during library is risen to the greatest extent as early as possible.It is false
If upper library A is in t0—t1Between reduce outbound to utilize the storage capacity Δ V, t of having more than needed1The reservoir inflow of the latter two scheduling mode at moment
It is completely superposed with the outbound process of reservoir level all same, the two.So outbound process becomes in entire schedule periods：
In formula,Segment length when Δ t is, k (t) are the storage outflow reduced.The storage of lower library B
Flow is by QB,in(t) become for QB,in’(t)：
QB, in(t)=QA, out(t- τ)+QJ (t), t=t0+ 1, t0+ 2 ..., n (2)
Wherein, τ is the difference of upper library to lower library and interval inflow to the flood transmission time in lower library, and QJ (t) is section flow.
The tune flood high water level of lower library B original flood season limit levels is ZB,max, using lower library rise the stage reservoir inflow reduce, by flood season limit level from
ZB,0It is increased to ZB,0', the tune flood high water level after raising is ZB, max '.If keeping downstream storage outflow and adjusting big vast high water level constant：
ZB, max=Z 'B, max(6)
Simultaneous formula (1)-(6) obtain, the flood season limit level after raising：
Z′B, 0=Z (V (ZB, 0)+ΔV)(7)
In formula, V () indicates that water level calculates the function of storage capacity, and Z () indicates that storage capacity calculates the function of water level.From formula
(7) find out, if keeping runoff reach constant, how many storage capacity more than needed of upper library, so that it may be lifted the flood season limit level in lower library
How many waters.
(2) between multi-reservoir compensation relationship foundation.
Step reservoir flood-water resources utilization based on storage capacity compensation, it is necessary to carry out library group's flood control compensative dispatching, using up can
Lower library flood season limit level can be raised, flood-water resources utilization rate is made to maximize.
1. the water storage state of sliding-model control upper pond.Since water storage is a continuously process, in order to carry out
It calculates, the water storage state discrete of upper pond is turned into several water levels, and can be with to the water level after each sliding-model control
Find out corresponding storage capacity by water level-storage capacity function V=f (h), and then by the compensation storage capacity dislocation corresponding to this water level
Into the connection reservoirs in downstream, go out what it can be raised finally by storage capacity-water level function h=f (V) rough calculation of lower reservoir
Flood season limit level.
2. the foundation of compensation relationship between multi-reservoir.It, can be with to the water position status of each sliding-model control of upper pond
A corresponding initial flood season limit level of lower reservoir is found out, substitutes into step reservoir storage capacity compensative dispatching model and is adjusted
It is whole, the Restricted Water Level for the lower reservoir that the flood control of Flood Prevention control point requires is met until finding out, by upper pond flood season
Point draws figure between water level and lower reservoir operating level during flood season, sees Fig. 2.It can be observed from fig. 2 that with upper pond flood season water
Position it is remoter apart from its flood season limit level, the flood season limit level of lower reservoir dynamically can be raised more, but upper pond there is always
One critical groundwater table, when its flood season level is at or below it, the flood season limit level of lower reservoir again cannot be raised more.
(3) the step reservoir utilization of flood resources regulation and operation based on storage capacity compensation.
Step reservoir utilization of flood resources based on storage capacity compensation is dispatched in actual operation, with as follows：Upper pond is still
Keep place where troops were originally stationed flood dispatching running way, the flood season limit level of lower reservoir raise it is only related with the water storage state of upper pond, according to
The achievement that model calculates, each upper pond flood season level is corresponding, and there are one the Restricted Water Levels of lower reservoir.
The method of the present invention is established according to the different real time water level situations of upper pond by the compensating action of upper pond
The lower reservoir Restricted Water Level graph of different schemes, the Restricted Water Level graph operability is strong, easy to use,
It has the advantage that：
1) present invention is to the of less demanding of flood forecasting, without considering the generation moment of end flood, it is only necessary to according to upper
The water level operating status in library of swiming determines the water level operating status of lower reservoir, without worry flood forecasting bring it is uncertain
Property, operability is high.
2) step reservoir is accounted for range by the present invention, by the compensation relationship of storage capacity between step reservoir come real
Existing flood-water resources utilization；Meanwhile compared to traditional by stages static flood season limit level, total storage capacity of Cascade Reservoirs is constant,
The risk of flood control is not increased additionally.
3) present invention can raise the operating water level in lower reservoir entire flood season to some extent, improve productive head, to
Increase power benefit in the case that water amount of power generating is identical；Pre flood period need not prematurely reduce reservoir level, and rear flood season can be compared with
It is lifted reservoir level soon, it is easier to which water storage as early as possible of seizing the opportunity improves reservoir and stores full rate；Utilize Flood as far as possible more
Resource increases power benefit, while also providing more Available water resources for basin below lower reservoir, can generate huge
Economic and social benefit.

Specific implementation mode
Below in conjunction with the accompanying drawings, the present invention is described in more detail.
Fig. 1 is to be put in storage change schematic diagram.
Fig. 2 is upstream and downstream flood season level relational graph.
Fig. 3 is each ten days dynamic control of limitation level in flood season hydrograph in Liujia Gorge (2594 scheme of Longan psyllid operating water level)

The overall flow of step reservoir flood-water resources utilization method based on above-mentioned storage capacity penalty method, the present invention is with the Yellow River
It is illustrated for upstream Longan psyllid and Liujia Gorge step reservoir.
For many years, the traffic control (especially Flood Control Dispatch) of the upper reaches of the Yellow River step hydropower station is established always in Longan psyllid~Liu Jia
On the basis of the two-reservoir combined traffic control in gorge.But in flood season, for the purpose of flood control safety, Liujiaxia Reservoir is reserved flood control
Storage capacity strictly presses single flood control limit, and reservoir level must be limited within flood season limit level, and flood season is caused largely to abandon water, and
Again because water is few after flood, operating water level is relatively low for a long time, causes prodigious electric quantity loss and the contradiction with water electricity consumption.It is same with this
When, it is most of since the hemiplegia and downstream excessive moisturizing that continues of the upper reaches of the Yellow River water causes the full rate of Longan psyllid reservoir storage very low
Storage capacity is idle, does not play the effect of its many years regulation and backbone reservoir well, also without more preferably embodying step power station connection
Close the benefit of traffic control.
For this purpose, according to the actual conditions that Liujia Gorge, Longan psyllid hydro plant with reservoir and its cooperation are dispatched, with Longan psyllid water
The available storage capacity compensation Liujiaxia Reservoir more than needed in library improves different flood season limit level institutes by flood season different time (ten days is unit)
The risk brought is realized the flood-water resources utilization of Liujiaxia Reservoir with storage capacity penalty method, excavates the potentiality of its Dispatching Flood,
Head benefit is improved, power benefit is increased.
(1) ten days process line of limited water level during flood season is divided to determine
A) typical flood selects
The flood into reservoir of Liujiaxia Reservoir comes from the Yellow River mainstream and section the Taohe River, Daxiahe River fork etc., accordingly, it is determined that
Flood process of reservoir line needed for each point of ten days process line of limited water level during flood season is also formed by stacking by the Yellow River mainstream and local inflow two parts.
The Yellow River mainstream part is Longan psyllid reservoir outbound flood hydrograph；Local inflow obtains in two steps：Design flood total amount is first sought, then
Select typical flood.Total amount part is provided by the design liaison station Guide station for annotating station data and Longan psyllid on the design liaison station of Liujia Gorge
Material subtracts each other to obtain, and the total amount formed with " Typical Year distribution " and " for upstream and downstream with frequency, section is corresponding " two kinds of different regions
In the maximum be determined as local inflow water；Typical flood then always come between occupied area the Taohe River red flag station of water 80% or so with
It is selected in the data of Daxiahe River folding bridge station, monthly selects two section model flood hydrographs.
B) typical flood is amplified
The ratio of the maximum value in each ten days Average Annual Runoff is accounted for section typical case according to each ten days Average Annual Runoff
Flood hydrograph zooms in and out, then again using being amplified with multiple proportions amplifying method, obtain different Flood Regions compositions each ten days,
Each frequency separation designed flood hydrograph.Again by the design flood into reservoir obtained by 1964,1967 typical floods through Longan psyllid tune
Flood calculation after outbound flood hydrograph formed from different Flood Regions each ten days, each frequency separation designed flood hydrograph distinguish
Stack combinations, and smooth appropriate is carried out, obtain the storage designed flood hydrograph of each ten days of Liujiaxia Reservoir.
C) ten days flood season limit level is divided to determine
Liujiaxia Reservoir is carried out to adjust big vast calculating, takes minimum starting-point detection of each ten days as each ten days flood season limit level, is shown in Table 1.
Using ten days as abscissa, flood season limit level is ordinate, and the flood season limit level point in each ten days is painted on graph paper, flood season limit level process is obtained
Line is shown in Fig. 3.
1 Liujiaxia Reservoir of table each ten days corresponding flood season limit level table (Longan psyllid Limited Water Level of Reservoir in Flood Season 2594m)
(2) the step reservoir flood-water resources utilization based on storage capacity penalty method
According to the actual conditions that Liujia Gorge, Longan psyllid hydro plant with reservoir and its cooperation are dispatched, especially upper dragon flying around sheep
Gorge reservoir has the available condition of storage capacity more than needed again, and the Restricted Water Level control of Liujiaxia Reservoir can be realized based on storage capacity penalty method
System achievees the purpose that flood-water resources utilization successively, that is, utilizes the storage capacity more than needed of Longan psyllid to calculate Liujia Gorge corresponding flood season
Limiting water level, as dynamic control of limitation level in flood season upper limit value, original design flood season limit level is as dynamic control lower limiting value.
According to early July to early September Longan psyllid, each ten days designed flood hydrograph in two library of Liujia Gorge and its two-reservoir combined anti-
Big vast scheduling rule inquires into each ten days difference flood season limit level of Liujiaxia Reservoir under each ten days difference operating water level of Longan psyllid respectively.
A) determine that upper pond is had more than needed storage capacity
Longan psyllid designs flood season limit level：2594m, each ten days operating water level numerical procedure are determined as：2594m, 2593m,
2592m, 2591m, 2590m, 2589m, 2588m, 2587m, 2586m, 2585m, 2584m, 2583m, 2582m, 2581m,
2580m, 2579m, 2578m, 2577m, 2576m, 2575m, 2574m, 2573m, 2572m, 2571m, 2570m amount to 25 sides
Case, correspondingly, storage capacity more than needed can determine.In the above embodiments, the flood storage simultaneously of certain storage capacity ratio is pressed in dragon, two library of Liu,
In view of starting-point detection of the Longan psyllid reservoir under each scheme is relatively low, when adjusting flood level to be less than limit of flood-season water level 2594m, water
Library under power generation requirements flow by letting out, and when adjusting flood level to be higher than limit of flood-season water level 2594m, reservoir is let out by the limitation of different frequency
It is let out under amount.
In order to give full play to the flood storage effect of two lab setting storage capacitys, dragon, two library flood storage of Liu need to control by a certain percentage
The reservoir storage for making two libraries compensates Liujiaxia Reservoir using Longan psyllid reservoir storage capacity more than needed, coordinates to adjust to reach two libraries
Flood and the purpose for combining flood control.Regulated and stored situation according to each scheme, dragon, two library flood storage of Liu ratio in (2.5~4.0): 1.0
Range carries out calculating control.In actual schedule, it can be carried out in this ratio in conjunction with flood synthesis situation according to the water storage level in two libraries
Control and adjustment, ensure Longan psyllid, Liujiaxia Reservoir flood control safety, coordinate water storage, give full play to the work of each dam safety evaluation storage capacity
With.
B) the water level operating status of lower reservoir is determined according to the water level operating status of upper pond
Since Longan psyllid reservoir and Longan psyllid, Liujia Gorge section each ten days have 2 different designed flood hydrograph phase groups
It closes, forms 4 Liujia Gorge storage designed flood hydrographs each ten days altogether.Therefore, under each scheme, Liujiaxia Reservoir tune flood calculates
4 flood season limit level values are obtained, are considered from flood control safety angle, choose minimum value as ten days Liujia Gorge flood season limit level.In this way,
Under each scheme, obtain sharing the flood control limit line that 7 values form from early July to early September, 25 schemes are just formed
25 flood control limit lines.Mode due to choosing minimum value can make individual flood season limit level values generate fluctuation, according to same ten days
The rule that Liujia Gorge flood season limit level is improved as Longan psyllid operating water level reduces, is modified, revised Liu to being worth individually
Family's each ten days Restricted Water Level of gorge reservoir is shown in Table 2.
Table 2 Liujia Gorge early July to early September Restricted Water Level control program correction chart
It is former using 25 flood control limit lines of different schemes as Liujiaxia Reservoir dynamic control of limitation level in flood season upper limit value
