Below to the fault section of the embodiment of the present invention（Also referred to as accident is interval）Judge and troubleshooting mode is situated between
Continue.
First, fault section judges
Fig. 4 is the flow chart that power network mixed line fault interval according to embodiments of the present invention judges, participates in Fig. 4, failure
Judgement can be in the following ways：
State change processing, system updates corresponding equipment on-line storehouse state according to terminal signaling state, including switch is closed
Isloation state, switch fault state etc., and power failure coloring is filled to system progress according to topological relation.
When gate out switch trips, the judgement of mixed type circuit is carried out, the judgment basis of mixed type circuit is power failure range
It is interior to include voltage-type automatic switch, it is judged to applying for " the secondary judgement timer of accident " during mixed type circuit and " end-state is sentenced
Determine timer ", go forward side by side and act therefore judge, the foundation of judgement is that gate out switch has protection signal or has substation accident always to believe
Number.
When gate out switch closes a floodgate, if there is voltage-type automatic switch in chargeable range, letter of application is called and calls out timer, is counted
When device voltage-type is switched on circuit X time limits time accumulative form.
Accident it is secondary judge timer expired when, again carry out accident determination processing, judgment basis be outlet open
There is protection signal pass or has substation accident resultant signal.（Because protection signal is possible to than slow on trip signal, therefore
If being judged during tripping operation, differ and surely obtain correct result, it is therefore desirable to judged again after being delayed several seconds）
When signal calls timer expired, to carry out signal calling processing because of the voltage-type switch of switch load side, call together
Call out after being disposed, judge whether the distribution wire there occurs accident, in the event of accident, then find out voltage-type circuit breaker lock area
Between scope.If containing current mode automatic switch in the scope of locking interval, application accident interval judges timer（Timer
Time and the decision of the terminal type of current mode switch）；If nothing, locking interval is set as that accident is interval and accident letter is updated
Breath.
When accident interval judges timer expired, according to finding out thing because of the fault-signal of switch load side current mode switch
Therefore it is interval, and update accident information.
When end-state judges timer expired, to not judge because line accident state where switch is in accident interval
It is stage, then interval to be set to accident because of the power failure range of switch, and update accident information.（Accident condition is avoided to be constantly in
The interval state of accident is not judged）
2nd, troubleshooting
Fig. 5 is the flow chart of power network mixed line fault processing according to embodiments of the present invention.As shown in figure 5, of the invention
The power network mixed line fault processing of embodiment can take in the following manner：
After accident interval judges successfully, the process of troubleshooting includes the isolating of accident interval, non-forced outage interval
Turn for releasing the process that backward accident interval restores electricity with accident interval.
Isolate between emergency area：The characteristics of based on voltage-type switch automatic separating fault interval, joint line accident interval
Isolation is handled by voltage-type circuit first, i.e., interval by the major break down of voltage-type switch isolation；And then accident interval border is opened
Put capable retrieval into, if there is the current mode switch of conjunction state on fault section border, illustrate accident interval in current mode switch load
Side, need to be further interval using current mode switch isolation accident.
Load transfer：Load transfer determines the interval that turn to supply first, and retrieval, which whether there is, to be turned to supply path.If there is can
The path supplied can be turned, start load branching algorithm, generation turns for strategy.
Operation order processing：What is generated turns for including voltage-type and current mode switch operation order in strategy, according to voltage and electricity
Flow pattern switchs different acting characteristics, and operation order need to be carried out to reconfigure editor.For same current mode switch, delete both
There is " closing operation " to have the operation order of " point operation " again；Operation order order is by first " current mode switch point " operation order, secondly " current mode
The principle rearrangement of switch conjunction " operation order, last voltage-type switching manipulation ticket.
Accident recovery is powered：After accident interval is released, the interval preferred power supply side interconnection switch that restores electricity of accident turns confession,
To ensure preferentially to use this line powering；After accident interval restores electricity, it is according to what is preserved before current system conditions and accident
Unite state vs, and generation returns to the recovery policy of system before accident.
It should be noted that can be in such as one group computer executable instructions the step of the flow of accompanying drawing is illustrated
Performed in computer system, and, although logical order is shown in flow charts, but in some cases, can be with not
The order being same as herein performs shown or described step.
