Description
Technical field
The present invention relates to a kind of traffic control drawing drawing method for making reservoir comprehensive benefit optimum, belongs to reservoir operational management
Technical field.
Background technology
Multiple purpose reservoir ruuning situation becomes a mandarin closely related with reservoir, and the change of natural river flow is often relatively more multiple
Miscellaneous, at present because scientific level is limited, can't forecast with unerring accuracy following long-period runoff process, and this storehouse operation of just feeding water brings
Very big difficulty.In order to be able to reasonably carry out dam safety evaluation, water resource is made full use of on the basis of safe and reliable, needed in run duration
The objective criteria for wanting a reservoir of planning strategies for store, discharge water, here it is using the starting point of graph of reservoir operation.
Graph of reservoir operation by tamper-proof line, limit supply line and it is anti-abandon the water levels such as waterline or water-retention discharge hydrograph is constituted, this
A little graphs are divided into several dispatch areas scheduling graph.When reservoir level or reservoir storage Luo Mou area, area's defined is just pressed
Quantity is discharging water.Graph of reservoir operation is the instrument for instructing year or carry-over storage operation, it assumes that past Streamflow Data is anti-
Following hydrologic regime is reflected, is formed using Streamflow Data drafting is lasted.
Reservoir operation is carried out using scheduling graph, the twenties in 20th century is started from, is proposed by Soviet Union scholar AA Vladimir Morozovs,
So far still it is widely used.It is using last Streamflow Data be adjusted calculate, various scheduling schemes are safely solved partially
The scope of application, i.e., for same decision-making (as ensured to supply water or increasing, reduce supplying water), with the hydrology of respective respective design fraction
The outer envelope curve of the various reservoir levels being likely to occur of situation is required scheduling line, and constitutes scheduling graph by them.According to scheduling
Figure carries out reservoir operation, can reach：When meeting with design low flow year, reservoir can guarantee that and each use water by method of operation work is ensured
The requirement of the normal water requirement in family and water level；When meeting with flat, high flow year, reservoir can be carried out by way of supplying water is increased, can be reasonably
Increase the output to each water user；When meeting with the special low flow year, reservoir can reasonably reduce each by way of supplying water work is reduced
The output of water user, to mitigate the normal benefit of each water user and effect loss of energy；Design flood is met with flood season or check mark
During quasi- flood, can guarantee that dam safety is passed the flood period, or meet with downstream flood control standard flood, the flood control requirement of sheltered ground can be met.
The method for drafting of annual-storage reservoir scheduling graph
1st, the drafting of tamper-proof line
According to the statistics of reservoir run-off, from the several of the close design dependability Po of the year water yield (or delivery period water yield)
The typical cases of different distribution become a mandarin process in individual year, and repair by the year water yield (or the delivery period water yield) control of respective design fraction
Just, i.e., the runoff process of each Typical Year is zoomed in or out by certain ratio so that their the year water yield (or delivery period water
Amount) it is equal to the analog value in design dependability time.Then from the beginning of from the end of term of supplying water by level of dead water, the Runoff adjustment of inverse time sequence is carried out
Calculate, obtain to the water-retention beginning by the reservoir storage (or water level) at the beginning of the period, it is desirable to which water-retention beginning water level is equal to level of dead water.Anti-
In pushing away calculating process, when water storage level reaches normal pool level, reservoir works by natural reservoir inflow.Take each year reservoir level process
Upper envelope curve be tamper-proof line.The all Fuzzy Period of Runoff Series (not being controlled scaling) after the destruction time can also be rejected, be pressed
Said method Extrapolation year by year, takes the upper envelope curve of reservoir level process over the years, as tamper-proof line.
2nd, the drafting of forced partial outage (water supply) line
Forced partial outage (water supply) line is inquired into tamper-proof line similar approach, and up time sequence is adjusted calculating, and draws each year water
Reservoir filling process, it is exactly forced partial outage (water supply) line then to remove envelope curve.
3rd, prevent abandoning the drafting of waterline
According to two Phase flow statistics of variables data, entered for the typical case of 1-Po from the fraction of the year water yield or the wet season water yield
Storehouse runoff process, power station discharges water by maximum discharge capacity or works by installed capacity, is opened by normal pool level from the water-retention end of term
Begin, inverse time sequence is counter to push away each moon reservoir level, to normal pool level is reached in delivery period, the reservoir level for connecting day part is as prevented abandoning
Waterline.Conditional power station, can calculate a series of actual measurement water year according to said method, but should not include these years
Year water yield is the time water yield of 1-Po more than fraction, then takes the interior envelope curve of each year reservoir level, as prevents abandoning waterline.
The method for drafting of carry-over storage scheduling graph
1st, the drafting of tamper-proof line
Method one：Select the time with such two Phase flow process to be the 1 calculating year, i.e., in the year, self-water-supplying
End of term reservoir stores full overyear storage and starts, and inverse time sequence is adjusted calculating, and to water-retention end of term reservoir level normal storage is reached
Water level, and the water-retention beginning reservoir level that arrives just has returned to the storage of overyear storage and worked to the last minute, in this year the interior water yield is much, no
Many, the reservoir level for connecting day part is tamper-proof line.If necessary, the unfavorable Typical Year of several Tendency analysis, the water yield can be chosen
Scale by proper proportion control, then carry out the regulating calculation of inverse time sequence, take the upper envelope curve of each year reservoir level process, as prevent broken
Bad line.
Method two：Using hydroelectric station design low water section two Phase flow process, self-water-supplying end of term reservoir stores full storage capacity for many years and opens
Begin, inverse time sequence is adjusted calculating, and takes the outer envelope curve of each year reservoir level graph, as tamper-proof line.
2nd, the drafting of forced partial outage (water supply) line
Method one：The time with such two Phase flow process is selected to be the 1 calculating year, from the end of term and the stagnant water of supplying water
Position starts, and carries out inverse time sequence regulating calculation, still disappears and drops down onto level of dead water to water-retention beginning reservoir level, and in this year the interior water yield is not
Less, seldom, the reservoir level for connecting day part is forced partial outage (water supply) line.
Method two：Aforementioned tamper-proof line is translated downwards, makes the water supply end of term and water-retention beginning reservoir level Chong Die with level of dead water,
As limit supply line.
3rd, prevent abandoning the drafting of waterline
The carry-over storage very high for regulation performance, can not draw it is anti-abandon waterline because this kind of reservoir abandons the water yield
It is general little, and abandon regimen condition and mostly occur in the flood season of continuous high flow year group, and the utilization of raising head can make up abandon water and
The electric quantity loss for causing, therefore often by normal pool level exerting oneself area as increasing down to tamper-proof line area above.
The deficiency of traditional method：Traditional method can be divided into Typical Year method when runoff process is chosen and remove the destruction time
Method.Typical Year method is the typical cases of different distribution in the several years for select the year water yield (or delivery period water yield) close design dependability Po
Become a mandarin process, and by the year water yield (or delivery period water yield) the control amendment of respective design fraction, i.e., by certain ratio by each allusion quotation
The runoff process in type year is zoomed in or out so that their the year water yield (or delivery period water yield) is equal to the design dependability time
Analog value；It is all Fuzzy Period of Runoff Series that scaling is not controlled after rejecting destroys the time to remove destruction time method.Using typical case
Year method exists in real work to be chosen and varies with each individual to Typical Year time, year, the scheduling for causing different designs personnel to draw
Figure is different.Variation analyses deficiency of the destruction time method to the fraction period is removed, water supply project is in design typically with year guarantee
Rate is designed, and scheduling graph then embodies day part in year and ensures water supply fraction, destruction is removed the whole year in time, it is possible to make year
Interior day part water supply fraction sample reduces, and affects the drafting precision of day part line in scheduling graph year.In addition, traditional method is calculated
The safe and reliable of reservoir operation operation guaranteed extent is paid attention in principle and theoretical foundation on the basis of water supply meets fraction, only,
Consideration shortcoming is made full use of to water resource；In one-year age, the requirement of quantity and guaranteed extent of the water user to supplying water is different
, such as rice ear sprouting period than the soaked field phase with greater need for supply water ensure, the power station withered phase come the water yield number carry out the water yield than flood season
The impact of how many pairs of annual electricity generating capacities is bigger, but traditional method does not more embody difference of the delivery period importance in different periods.
