The content of the invention
In order to which the throwing of the prepared auto restart provided pressing plate is made to move back the practical operation situation that strategy more meets power grid, the present invention proposes one
The optimal throwing annealing method of prepared auto restart pressing plate that kind is checked based on minute wheel time, step are as follows:
A kind of optimal throwing annealing method of prepared auto restart pressing plate checked based on minute wheel time, is included the following steps:
(1)According to the attribute of prepared auto restart, the first round check is carried out for " putting on the spot " and " automatically controlling " prepared auto restart;
(2)According to the attribute of prepared auto restart, the second round school is carried out for " exiting on the spot " and " non-automatic control " prepared auto restart
Core.
As a further improvement on the present invention:When first round is checked, by " putting on the spot " and " automatically controlling " prepared auto restart
Whether whether working bus bar can be remotely controlled with responsible consumer, the virtual condition of prepared auto restart, prepared auto restart and the work of prepared auto restart is female
The comprehensive weight of the absolute value of the load of line determines priority, and issues remote control command and according to priority carry out throwing and move back operation.
As a further improvement on the present invention:First round check when, if some N-1 device fails cause it is multiple
Prepared auto restart acts, while is checked after prepared auto restart action by trend and find to cause apparatus overload, then needs " throwing on the spot to action
Enter " and " automatically controlling " prepared auto restart exited in certain sequence;Handle start when, first assume all " putting on the spot " and
" automatically controlling " prepared auto restart is input state, is checked by N-1 and detects which prepared auto restart needs exits, so only needing to consider
The priority exited, the order of input are exactly the opposite;Then issue remote control command according to priority carry out throw move back operation;
Exiting the factor that logic needs consider includes:
A, whether with responsible consumer, the preferential of no responsible consumer exits the working bus bar of prepared auto restart;
B, the virtual condition of prepared auto restart, prepared auto restart virtual condition are that exit preferential exits;
C, can prepared auto restart be remotely controlled, and what prepared auto restart can be remotely controlled preferentially exits;
D, the absolute value of the load of prepared auto restart working bus bar, the small prepared auto restart of prepared auto restart working bus bar institute on-load preferentially move back
Go out;
What the first round was checked exits priority formula:
Initial priority=K1*V1+K2*V2-V3-K4*V4+K5
In formula, K1 represents prepared auto restart actual motion state weight;V1 represents the currently practical operating status of prepared auto restart, value
Respectively:Automatic switching, which exits, is arranged to 1, and other states are arranged to 0;K2 represents the weight that can prepared auto restart be remotely controlled;V2 is represented
Can prepared auto restart be remotely controlled, and what can be remotely controlled is arranged to 1, it is impossible to which remote control is arranged to 0;V3 represents the load of prepared auto restart working bus bar
Absolute value;K4 represents whether prepared auto restart has responsible consumer weight;V4 represents whether prepared auto restart has responsible consumer, with responsible consumer
1 is arranged to, is otherwise 0;K5 is weight base value.
As a further improvement on the present invention:K1 default values are arranged to 10000;K2 default values are arranged to 1000;K4 is default
Value is arranged to 3000;K5 default values are arranged to 4000.
As a further improvement on the present invention:It is female by the absolute value of the load of working bus bar, work when second round is checked
Whether the comprehensive weight with responsible consumer determines priority to line, according to priority provides throwing and moves back strategy.
As a further improvement on the present invention:When second round is checked, no longer to gauged standby in the first round
It hauls oneself willingly into and is checked;If some N-1 device fails causes multiple prepared auto restarts to act, while draws after simulating prepared auto restart action
Play apparatus overload, then need to exit the prepared auto restart of action in certain sequence, handle start when, first assume all standby
It is input state to haul oneself willingly into, and state setting is moved back by the actual throwing of strategy for the prepared auto restart that strategy has been given in the first round,
Detection which prepared auto restart needs are checked by N-1 to exit, so only need to consider the priority exited, the order of input just phase
Instead;Here only need to provide strategy, actual straighforward operation need not be carried out;
What the second round was checked exits priority formula:
K=- V3-K4*V4+K5,
In formula, V3 represents the absolute value of the load of prepared auto restart working bus bar;K4 represents whether prepared auto restart has responsible consumer
Weight;V4 represents whether prepared auto restart has responsible consumer, and 1 is arranged to responsible consumer, is otherwise 0;K5 represents weight base value.
As a further improvement on the present invention:K4 default values are arranged to 3000;K5 default values are arranged to 4000.
Compared with the prior art, the present invention has following good effect:(1)The present invention has considered point of prepared auto restart
The prepared auto restarts attributes such as class, virtual condition and load sharing characteristic, so that the prepared auto restart pressing plate throwing provided is moved back strategy and more met
The practical operation situation of power grid;(2)Category of the present invention carries out minute wheel time and checks, and can first be checked for " automatically controlling " prepared auto restart
And directly hair telecommand carry out throw move back operation, by " non-automatic control " prepared auto restart be put into the second round check in, not only shorten
The time thrown and move back strategy is provided, and after improving failure throws the response speed moved back.
Specific embodiment
The technical solution that the invention will now be described in detail with reference to the accompanying drawings:
It initially sets up the throwing of prepared auto restart pressing plate and moves back model, to facilitate the discussion of embodiment:Prepared auto restart model includes prepared auto restart name
Claim, prepared auto restart type(The standby throwing of mother or the standby throwing of equipment), the equipment that includes(Circuit or transformer), switch, busbar, throwing move back setting
(It exits, put on the spot on the spot, automatically controlling, non-automatic control), throw move back shaping modes(Stopping, open loop execution, closed loop), pressing plate
Signaling point and whether comprising grading.Prepared auto restart model disconnects as shown in Figure 1, switching hollow expression in Fig. 1, and solid expression is closed
It closes.
For the prepared auto restart universal model of Fig. 1, charge condition and the operation condition such as table 1 of prepared auto restart.
Table 1
|
Mother is standby to throw |
Equipment is standby to throw |
Charge condition |
Busbar A Dai electricity && busbar B Dai electricity s && switches C is hot standby |
Busbar A Dai electricity && busbar B Dai electricity s && switches B is hot standby |
Operation condition |
Busbar A Bu Dai electricity s && switches C is hot standby |
Busbar A Bu Dai electricity && busbar B Bu Dai electricity s && switches C closes &&(It is hot standby to switch B) |
When carrying out N-1 scannings, it is necessary first to the prepared auto restart that cannot be charged is filtered out according to the charge condition of table 1.For
Prepared auto restart model as shown in Figure 1, it will usually generate 4 prepared auto restart records, i.e. the 2 of mother prepared auto restart prepared auto restart records(It opens
C is closed for busbar A and switch C for busbar B)And 2 prepared auto restarts record of equipment prepared auto restart(It is standby female for busbar A and switch A to switch B
Line B).In general, mother prepared auto restart and equipment prepared auto restart only have part record that can meet charge condition.Specific to such as Fig. 1 institutes
The prepared auto restart model shown only switchs C and meets charge condition for busbar A and switch C for busbar B, and switchs B for busbar A and open
It closes A and is unsatisfactory for charge condition for busbar B, so first filtering out the prepared auto restart for being unsatisfactory for charge condition under this method of operation.
, it is necessary to be scanned successively to all N-1 faulty equipments after failure generation, rough estimates are by faulty equipment institute
The information and corresponding prepared auto restart sequential relationship of caused action prepared auto restart.When specifically strategy is moved back in the throwing of processing prepared auto restart pressing plate,
Should by failure can caused by action prepared auto restart quantity from less to more successively carry out failure check, i.e.,:First checking can cause
Action prepared auto restart the few failure of quantity, it is rear check institute can caused by action prepared auto restart quantity more than failure, so as to completely
Prepared auto restart is put into greatest extent on the premise of sufficient power grid operation.
After failure occurs, take measures using the optimal annealing method of throwing of the prepared auto restart pressing plate checked based on minute wheel time and throwing is provided
Strategy is moved back, this method comprises the following steps:
(1)According to the attribute of prepared auto restart, the first round check is carried out for " putting on the spot " and " automatically controlling " prepared auto restart;
(2)According to the attribute of prepared auto restart, the second round school is carried out for " exiting on the spot " and " non-automatic control " prepared auto restart
Core.
Wherein step(1)Specific method be:If some N-1 device fails causes multiple prepared auto restarts to act, together
When prepared auto restart action after checked by trend and find to cause apparatus overload, then need to " on the spot put into " of action and " control automatically
System " prepared auto restart is exited in certain sequence;When handling beginning, first assume that all " putting on the spot " and " automatically controlling " is standby
It is input state to haul oneself willingly into, and is checked by N-1 and detects which prepared auto restart needs exits, so only needing to consider to exit preferential
Grade, the order of input are exactly the opposite;Then issue remote control command according to priority carry out throw move back operation;
Exiting the factor that logic needs consider includes:
A, whether with responsible consumer, the preferential of no responsible consumer exits the working bus bar of prepared auto restart;
B, the virtual condition of prepared auto restart(It puts into or exits), prepared auto restart virtual condition is that exit preferential exits;
C, can prepared auto restart be remotely controlled, and what prepared auto restart can be remotely controlled preferentially exits;
D, the absolute value of the load of prepared auto restart working bus bar, the small prepared auto restart of prepared auto restart working bus bar institute on-load preferentially move back
Go out;
In summary factor, sets to obtain that the first round checks exits priority formula by different weights:
Initial priority=K1*V1+K2*V2-V3-K4*V4+K5
In formula, K1 represents prepared auto restart actual motion state weight, and default value is arranged to 10000;It is current that V1 represents prepared auto restart
Actual motion state, value are respectively:Automatic switching, which exits, is arranged to 1, and other states are arranged to 0;K2 represents prepared auto restart energy
The weight of no remote control, default value are arranged to 1000;Can V2 represent prepared auto restart and be remotely controlled, and what can be remotely controlled is arranged to 1, it is impossible to remote control
It is arranged to 0;V3 represents the absolute value of the load of prepared auto restart working bus bar;K4 represents whether prepared auto restart has responsible consumer weight, lacks
Province's value is arranged to 3000;V4 represents whether prepared auto restart has responsible consumer, and 1 is arranged to responsible consumer, is otherwise 0;K5 is power
Weight base value, default value are arranged to 4000.
Wherein step(2)Specific method be:No longer to gauged prepared auto restart in the first round in second round
It is checked;If some N-1 device fails causes multiple prepared auto restarts to act, while simulates to cause after prepared auto restart acts and set
Standby overload, then need to exit the prepared auto restart of action in certain sequence, when handling beginning, first assumes all prepared auto restarts
It is input state, moves back state setting by the actual throwing of strategy for the prepared auto restart that strategy has been given in the first round, pass through
N-1, which is checked, detects which prepared auto restart needs exits, so only needing to consider the priority exited, the order of input is exactly the opposite;
Here only provide throwing and move back strategy, actual straighforward operation need not be carried out;
Set to obtain that the second round checks exits priority formula by different weights:
K=–V3–K4*V4+K5
In formula, V3 represents the absolute value of the load of prepared auto restart working bus bar;K4 represents whether prepared auto restart has responsible consumer
Weight, default value are arranged to 3000;V4 represents whether prepared auto restart has responsible consumer, and 1 is arranged to responsible consumer, is otherwise 0;
K5 represents weight base value, and default value is arranged to 4000.
Lower mask body discusses the power grid such as Fig. 2, it is assumed that circuit 1 breaks down, and caused can act prepared auto restart includes 101A
Reserve line 1, A station 500A stand 500A for 501 for 501 and B.It can cause apparatus overload after above-mentioned 3 prepared auto restarts action, therefore need
It takes measures that prepared auto restart is carried out throwing to move back and provide throwing for staff to move back strategy.Wherein 1 time sequence parameter of 101A reserve lines is low,
A station 500A are high for 501 time sequence parameters for 501 and B station 500A.Following several feelings then can be divided into according to the virtual condition of each prepared auto restart
Condition:
A) if 101A reserve lines 1, need not be further to A because it does not possess remote control property to put on the spot
The 500A that stands is checked for 501 and B stations 500A for 501, it is only necessary to which strategy is moved back in the throwing for providing input 101A reserve lines 1.
B) if 101A reserve lines 1 possess remote control property, then no matter 101A reserve lines 1 are currently input to automatically control
Still exit, only strategy to be given of checking then need not further check A and stand 500A for 501 for input 101A reserve lines 1
And whether B stations 500A needs to put into for 501;If the check strategy provided needs further school to exit 101A reserve lines 1
Whether core A station 500A need to put into for 501 and B stations 500A for 501, it is assumed that A station 500A are also certainly for 501 for 501 and B station 500A
Dynamic control, and the 500A at A stations is 5MW+j3MVar for the load of 501 working bus bar, and the 500A at B stations is for 501 work
The load of busbar is 3MW+j1MVar, while the busbar of 2 substations then first carries out the first round time school without responsible consumer
Core, by step(1)In formula can calculate 101A reserve lines 1 and B station 500A for 501 exit priority than A stand
500A for 501 exit priority will height, therefore 101A reserve lines 1 and B station 500A should preferentially be exited for 501, that is,
The 500A at A stations should preferentially be put into for 501.Due to such situation be not related to " exiting on the spot " and " non-automatic control " prepared auto restart and
It is checked by the first round and can determine that throwing moves back strategy and takes measures, there is no need to the checks of the second round.
C) if 101A reserve lines 1 possess remote control property, and requirement exits 101A for line in strategy to automatically control
Road 1, while A station 500A are non-automatic control for 501 for 501 and B station 500A, and to exit on the spot;If in the first round school
It detects that 101A reserve lines 1 are should be in core to exit, then needs to continue to verify A stations 500A into the check of the second round for 501
And whether B stations 500A should put into for 501, it is assumed that the 500A at A stations carries responsible consumer for 501, and the 500A at B stations is without important
User, by step(2)In formula can calculate the 500A at A stations and exited for 501 500A that stands of priority ratio B for 501
Priority is low, i.e., should preferentially exit the 500A at B stations for 501, therefore the throwing provided moves back strategy should preferentially to put into the 500A at A stations
Standby 501.
