Below to the fault section of the embodiment of the present invention(Also referred to as accident section)Judgement and troubleshooting mode are situated between
It continues.
One, fault section judges
Fig. 4 is the flow chart of power grid mixed line fault according to the ... of the embodiment of the present invention section judgement, participates in Fig. 4, failure
Following manner may be used in judgement:
State change processing, system update corresponding equipment on-line library state according to terminal signaling state, including switch closes
Isloation state, switch fault state etc., and system fill having a power failure according to topological relation and is coloured.
When gate out switch trips, the judgement of mixed type circuit is carried out, the judgment basis of mixed type circuit is scope of power outage
Interior includes voltage-type automatic switch, is determined as application " the secondary judgement timer of accident " when mixed type circuit and " end-state is sentenced
Determine timer ", it goes forward side by side and acts therefore judge, the foundation of judgement, which is gate out switch, to be had protection signal or have substation accident always to believe
Number.
When gate out switch closes a floodgate, if there is voltage-type automatic switch in chargeable range, timer is called out in letter of application call, is counted
When device X time limits for being switched by voltage-type on circuit time accumulative form.
When accident secondary judgement timer expired, accident determination processing is carried out again, and judgment basis is that outlet is opened
There is protection signal in pass or has substation accident resultant signal.(Because than slow on trip signal, therefore protection signal is possible to
If being judged when tripping, differ and surely obtain correct result, it is therefore desirable to be judged again after being delayed several seconds)
When signal calls timer expired, to carry out signal calling processing because the voltage-type of switch load side switchs, call together
It calls out after being disposed, judges whether the distribution wire has occurred accident, in case of accident, then find out voltage-type circuit breaker lock area
Between range.If containing current mode automatic switch in locking interval range, apply for that accident section judges timer(Timer
Time and the decision of the terminal type of current mode switch);If nothing, locking section is set as accident section and updates accident letter
Breath.
When accident section judges timer expired, according to finding out thing because of the fault-signal of switch load side current mode switch
Therefore section, and update accident information.
When end-state judges timer expired, to not judge because line accident state where switch is in accident section
Stage then being set as accident section because of the scope of power outage of switch, and updates accident information.(Accident condition is avoided to be constantly in
The state in accident section is not judged)
Two, troubleshooting
Fig. 5 is the flow chart of power grid mixed line fault processing according to the ... of the embodiment of the present invention.As shown in figure 5, of the invention
The power grid mixed line fault processing of embodiment can take following manner:
After accident section judges successfully, the process of troubleshooting includes being isolated of accident section, non-forced outage section
Turn the process for restoring electricity to accident section after being released with accident section.
It is isolated between emergency area:The characteristics of automatic separating fault section being switched based on voltage-type, joint line accident section
Isolation is pressed voltage-type circuit and is handled first, i.e., by voltage-type switch isolation major break down section;And then accident interval border is opened
It puts capable retrieval into, if there is the current mode switch of conjunction state on fault section boundary, illustrates accident section in current mode switch load
Side need to further use current mode switch isolation accident section.
Load transfer:Load transfer determination first will turn the section supplied, and retrieval, which whether there is, to be turned for path.If there is can
It can turn the path supplied, start load branching algorithm, generate and turn 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, need to carry out reconfiguring editor to operation order.For same current mode switch, delete both
There is " closing operation " and has the operation order of " point operation ";Operation order sequence 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 section releases, the preferred power supply side interconnection switch that restores electricity in accident section turns to supply,
To ensure preferentially to use this line powering;After accident section restores electricity, it is according to what is preserved before current system conditions and accident
Unite state vs, generates the recovery policy of system before the accident that is restored to.
It should be noted that step shown in the flowchart of the accompanying drawings can be in such as a group of computer-executable instructions
It is executed in computer system, although also, logical order is shown in flow charts, and it in some cases, can be with not
The sequence being same as herein executes shown or described step.
Obviously, those skilled in the art should be understood that each module of the above invention or each step can be with general
Computing device realize that they can be concentrated on a single computing device, or be distributed in multiple computing devices and formed
Network on, optionally, they can be realized with the program code that computing device can perform, it is thus possible to which they are stored
Be performed by computing device in the storage device, either they are fabricated to each integrated circuit modules or by they
In multiple modules or step be fabricated to single integrated circuit module to realize.In this way, the present invention is not limited to any specific
Hardware and software combines.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
