One, fault section judges
Fig. 4 is the flow chart judged according to the electrical network mixed line fault of embodiment of the present invention interval, participates in Fig. 4, and breakdown judge can in the following ways:
State variation process, the equipment on-line storehouse state that system is corresponding according to terminal signaling state updating, comprise switch close point state, switch fault state etc., and according to topological relation to system fill power failure painted.
When gate out switch trips; carry out the judgement of mixed type circuit; the judgment basis of mixed type circuit comprises voltage-type automatic switch in power failure range; " accident secondary judges timer " and " end-state judgement timer " is applied for when being judged to be mixed type circuit; go forward side by side and act therefore judge, the foundation of judgement is that gate out switch has protection act signal or has substation accident resultant signal.
When gate out switch closes a floodgate, if there is voltage-type automatic switch in chargeable range, then letter of application is called and is called out timer, and the time of timer was added up to form by the X time limit of voltage-type switch on circuit.
Time accident secondary judges timer expired, carry out accident determination processing again, judgment basis is that gate out switch has protection act signal or has substation accident resultant signal.(because slow likely than on trip signal of guard signal, therefore carry out judging during tripping operation, differ and obtain correct result surely, therefore need time delay to judge again after several seconds)
During signal calling timer expired, signal calling process is carried out to the voltage-type switch of essential factor switch load side, after calling is disposed, judges whether this distribution wire there occurs accident, if the accident of there occurs, then find out voltage-type circuit breaker lock interval range.If contain current mode automatic switch in locking interval range, then apply for judging between emergency area timer (terminal type of timer periods current mode switch again determines); If nothing, then to be set as between degating region between emergency area and to upgrade accident information.
When judging timer expired between emergency area, the fault-signal according to essential factor switch load side current mode switch is found out between emergency area, and upgrades accident information.
When end-state judges timer expired, to be in non-decision stage between emergency area because of switch place line accident state, then the power failure range of essential factor switch is set between emergency area, and upgrades accident information.(avoiding accident condition to be in the state do not judged between emergency area) always
Two, troubleshooting
Fig. 5 is the flow chart of the electrical network mixed line fault process according to the embodiment of the present invention.As shown in Figure 5, the electrical network mixed line fault process of the embodiment of the present invention can be taked with under type:
Judge between emergency area successfully, the process of troubleshooting comprises the isolation between emergency area, turning of non-accident interruption interval supplies and remove the process restored electricity between backward emergency area between emergency area.
Isolate between emergency area: based on the feature in voltage-type switch automatic separating fault interval, first the isolation between joint line emergency area presses the process of voltage-type circuit, namely interval by the major break down of voltage-type switch isolation; And then boundary switch between emergency area is retrieved, if there is the current mode switch of conjunction state on fault section border, illustrate in current mode switch load side between emergency area, need to adopt further between this current mode switch isolation emergency area.
Load transfer: first load transfer determines the interval that will turn confession, whether retrieval exists turns for path.If there is the path that may turn confession, start load transfer plan algorithm, generate and turn for strategy.
Operation order process: turning of generation comprises voltage-type and current mode switch operation order in strategy, according to the different operating characteristics of voltage and current type switch, need reconfigure editor to operation order.For same current mode switch, delete the operation order that existing " closing operation " has again " point operation "; Operation order order is by the principle rearrangement of first " current mode switch divides " operation order, secondly " current mode switch conjunction " operation order, last voltage-type switching manipulation ticket.
Accident recovery is powered: after removing between emergency area, the preferred power supply side interconnection switch that restores electricity between emergency area turns confession, to ensure preferentially to adopt this line powering; After restoring electricity between emergency area, according to the system mode contrast of preserving before current system conditions and accident, generate the recovery policy returning to system before accident.
It should be noted that, can perform in the computer system of such as one group of computer executable instructions in the step shown in the flow chart of accompanying drawing, and, although show logical order in flow charts, but in some cases, can be different from the step shown or described by order execution herein.
