Maximum output, minimum load, maximum daily amplitude, head constraint etc..On the basis of general-purpose scheduler class of procedure, calculated according to business
Demand it is different, also derive two subclasses: runoff dispatching rule subclass and Dispatching Flood rule subclass.
(3-3-1) runoff scheduling rule subclass
According to the dispatching rule of all kinds of reservoirs, the runoff scheduling rule of reservoir can be classified as to scheduling graph control and control mould
Formula control two kinds, when reservoir is without particular/special requirement by scheduling graph run, when reservoir need to meet specific control mode, then according to
Control model operation.
1. graph of reservoir operation class
Scheduling graph is the core of runoff scheduling rule, and under the premise of other no particular schedules are regular, reservoir is according to tune
Degree figure operation.
2. reservoir control model
In the period for having specific reservoir demand for control, the operation that reservoir is controlled with specific control model regulation is also needed
Journey has the case where conflict in control model and graph of reservoir operation, should for controlling the mode priority it is higher.
(3-3-2) Dispatching Flood rule subclass
For the safety for ensuring dam hinge and downstream guard plot, Flood Season of Reservoir is usually run according to Flood Control Dispatch mode, hair
The emerging benefit operation such as electricity and shipping must all submit to Flood Control Dispatch.It is special according to downstream flood control object geographic location and reservoir operation
Point, Flood Control Dispatch can be divided into routine dispactching and compensative dispatching, and two kinds of scheduling rules carry out in step 5 according to power station type
Selection.
1. routine dispactching is regular
Suitable for unshielded object or the lesser reservoir of downstream protection object interval inflow.Under normal conditions, corresponding to adjust
Metric can then indicate are as follows: input: flood stage-reservoir inflow-operating water level；Output: letdown flow-retains flow-water level
Boundary.Flood stage and reservoir inflow attribute in Flood Control Dispatch rule be it is necessary, letdown flow and retain in flow attribution
Alternative, operating water level and water level frontier properties are optional.
2. compensative dispatching is regular
The case where suitable for having protection object or cooperation lower reservoir shared flood control task, reservoir is according to flood control at this time
The flow or water level control letdown flow at control point.Flood control control point includes hydrometric station and lower reservoir, such as Xiluodu reservoir root
Scheduling is compensated according to Li Zhuanzhan flow, Xiluodu reservoir cooperation Three Gorges Reservoir carries out Dispatching Flood and Three Gorges Reservoir according to Shashi
Water level compensates scheduling.Compensative dispatching increases the condition at flood control control point on the basis of routine dispactching, therefore, input master
It to be control point flow or water level attribute, reservoir inflow and operating water level attribute are optional；Output can be control point flow, control
It puts water level, letdown flow and retains flow.In view of reservoir may implement compensative dispatching, compensative dispatching rule to multiple control points
It can be described as: input: priority-flood stage-control point flow-control point water level-reservoir inflow-operating water level；Output:
Control point flow-control point water level-letdown flow-retains flow-water level boundary.When compensating scheduling, need under input
The section discharge process of trip flood control object.If Rule of judgment is control point water level, water level-stream of section where needing control point
Magnitude relation.
Step 4: generalization multi-reservoir power generation dispatching
In analysis Design of Reservoirs task, different times scheduling rule and specific requirement related with reservoir regulation mode
On the basis of defined, in conjunction with reservoir routine dispactching figure, storage balance control model, water level control mode, flow are proposed out
Control model, go out force control mode, 6 kinds of control modes of scheduling graph control model and mixing control model carry out different schedule periods and
Different water situation lower storage reservoir power generation dispatching operational process calculate.Realizing hydropower station management and running process generalization simulation
On the basis of, the featured function of system is that can carry out generalization to history runoff also now calculates.Runoff also shows calculation basis " on first
The principle in trip downstream again ", " first tributary again mainstream ", inquires into reservoir storage outflow process by above-mentioned routine dispactching mode first,
And lower reservoir is inquired by the reduction flow of the storage of upper pond, storage outflow and lower reservoir according to water balance equation
Also show flow, realizes that the generalization of multi-reservoir reservoir inflow also shows computing function.Specific step is as follows:
The highest level reservoir that (4-1) is obtained in specified basin is numbered, it is specified that mainstream is superior to its tributary rank, downstream
Reservoir is superior to upper pond.It is assumed that k is highest level river, M is the highest level reservoir on river k, then (k, M) is
Basin highest level reservoir number.If Rev represents river number, Res represents reservoir number, enables Rev=k, Res=1, and entrance is next
Step；
(4-2) starts to calculate from the most upstream reservoir (Rev, 1) of river Rev；
(4-3) calculates reservoir two Phase flow.The storage of most upstream reservoir is natural runoff, and non-most upstream reservoir is according under
Formula calculates, into next step；
In formula,Ik,mRespectively indicate reduction and the current runoff of reservoir (k, m)；Ik,m、Ok,m-1Respectively indicate reservoir
The storage outflow of the reservoir inflow and reservoir (k, m-1) of (k, m)；Qk,mIndicate the local inflow of reservoir (k, m-1) and (k, m).
In formula,Respectively indicate reservoir (ki,Ni) storage and storage outflow；kiIt indicates to import reservoir (k, m)
Tributary number；(ki,Ni) indicate tributary kiUpper afterbody reservoir.
(4-4) calculates reservoir (Rev, Res) outbound process according to routine dispactching module, and enables reservoir Res=Res+1, into
Enter in next step；
(4-5) judges whether to meet " Rev=k and Res=M+1 ", if so, calculated to highest level reservoir (k, M),
Terminate；If it is not, entering in next step；
(4-6) judges whether to meet " Rev=kiAnd Res=Ni+ 1 ", if so, tributary k has had been calculatediUpper afterbody
Reservoir (ki,Ni), the calculating of previous stage river is gone back to, step (4-3) is transferred to；If it is not, entering in next step；
(4-7) judges whether next stage reservoir has tributary storage.If nothing, (4-4) is gone to step；If so, entering in next step；
(4-8) obtains tributary number kiAnd all N on the tributaryiGrade Reservoir information.Enable Rev=kiAnd Res=1, turn
Enter step (4-2).
Step 5: generalization multi-reservoir Flood Control Dispatch
For different types of power station, system takes different scheduling modes to carry out reservoir regulation for flood control, realizes multi-reservoir
Generalization Flood Control Dispatch.
(5-1) is without downstream flood control task power station
1. run-off river power station
Input condition: nothing
Scheduling mode: when water, which is less than, lets out ability under power station, power station remains normal according to storage balance control, reservoir is gone out
Water storage level；When water is greater than power station conveyance capacity, power station is controlled according to maximum discharge capacity, and reservoir passively raises operation water
Position, then gradually returns to normal pool level.
2. non-run-off river power station
Input condition: power generation dispatching figure
Scheduling mode: when water, which is less than, lets out ability under power station, power station is run according to power generation dispatching figure, controls last water level not
More than normal pool level, if power station is stored according to guaranteeing to contribute to normal pool level without power generation dispatching figure, it is flat then to press out storage
Weighing apparatus control；When water is greater than power station conveyance capacity, power station is according to power generation dispatching figure water storage, if without power generation dispatching figure, by guaranteeing
Power water storage, if reservoir level is more than normal pool level, operating water level is passively raised according to the control of maximum discharge capacity in power station.
(5-2) has downstream flood control task power station
1. fixed lower discharge mode
Input condition: the flood control safety letdown flow under different standard of flood
Scheduling mode: when water is less than flood control safety letdown flow, power station keeps flood to restrict water supply according to storage balance control
Position operation；When water is greater than flood control safety letdown flow, power station is according to the safe letdown flow under current flood or retains stream
Amount control is let out, while guaranteeing that period end water level is no more than upper water level for flood control；If current operating water level reaches upper water level for flood control, power station is pressed
Ensure dam safety according to spacious let out of discharge capacity；In the water-break stage, storage capacity is emptied rapidly.
2. compensative dispatching mode
Input condition: flood control control point control flow or water level
Scheduling mode: according to current reservoir water and downstream interval inflow, judge compensative dispatching conditions for use.If not having
Compensative dispatching condition, then power station keeps flood season limit level operation according to storage balance control；Otherwise, power station is according to flood control control point
Control flow or water level and downstream section draw that water is counter to push down vent flow, while guaranteeing that period end water level is no more than upper water level for flood control；
If current operating water level reaches upper water level for flood control, power station ensures dam safety according to spacious let out of discharge capacity.Multiple reservoirs are to identical
When the compensative dispatching of control point, if the letdown flow of other reservoirs is unknown, current Reservoir Operation flow can not be calculated.Therefore, it examines
The control point that will control flood is considered as reservoir operation object, and the flow control of upstream compensation reservoir is carried out when carrying out control point scheduling.
If current scheduling object is compensating reservoir, storage balance control is first pressed out, while marking reservoir state, compensation control point
With available storage capacity, the Flood Control Dispatch of other reservoirs is then carried out: if current scheduling object is flood control control point, according to becoming a mandarin
Judge whether to regulate and store, it, can in conjunction with each reservoir if then searching for the reservoir that all compensation control points are current control point
Ratio is carried out with storage capacity to retain.
