Embodiment
Below in conjunction with accompanying drawing, technical characterictic and the advantage with other above-mentioned to the present invention are described in more detail.
Described power distribution network accident is distribution network failure self-healing processing.
The scope of fault feeder contact group is guilty culprit feeder line and the feeder line that has with it communication relationship.
Refer to shown in Fig. 1 its flow chart that is a kind of power distribution network accident overall process inversion method take feeder line contact group as unit of the present invention; Wherein, the flow process of power distribution network accident overall process inversion method is:
Step a, the historical electricity distribution network model of read failure feeder line contact group, the metric data that loads inverting zero hour forms the real-time storehouse of the inverting state section take feeder line contact group as unit.
Initial section metric data when fault data comprises fault; fault contact group model; the history of fault self-recovery processing procedure and dynamic data (comprising: fault message summary; protection and warning information; fault detect information, fault location result, fault isolation schemes and execution result; fault recovery scheme and execution result, metric data change information).The number of using in this step is a part for fault data.
In the time breaking down, self-healing handling procedure is preserved binary file of these data formations.Fault data is stored on historic data server, take fault contact group and fault moment as unit storage, is eachly saved as an independently file.
When read failure data, according to feeder line group and fault moment, select corresponding fault data file, then from corresponding fault data file, read corresponding fault data as required.
Step b, reads history and the dynamic data of accident process; Comprise: fault message summary, protection and warning information, fault detect information, fault location result, fault isolation schemes and execution result, fault recovery scheme and execution result, metric data change information.
Step c, the alarm event to the accident process obtaining in step b and accident treatment process event sort according to sequencing, formation accident overall process list of thing.
Steps d, loads fault message summary, and initialization the first pointer and the second pointer, points to and treats inverting event and the event stage for the treatment of inverting respectively.
Described the first pointer, for treating inverting event pointer, points to the inverting event for the treatment of; Described the second pointer, for treating inverting event stage pointer, points to the event stage for the treatment of inverting.
Step e, from sequential inversion, single step invertion with by selecting at least one to carry out inverting three kinds of inverting modes of event procedure inverting;
Will be according to feeder line group and corresponding fault moment when inverting, select corresponding fault data file to carry out inverting, in the time that multiple feeder line groups break down simultaneously, be to carry out one by one inverting.

8. the power distribution network accident overall process inversion method take feeder line contact group as unit according to claim 7, is characterized in that, describedly by the detailed process of event procedure inverting is:
Step e31, obtains the stage of inverting event and treats the inverting event stage;
Step e32, according to the stage of inverting event, obtains inverting event sets, according to treating that the inverting event stage obtains treating inverting event sets;
Step e33, judges whether the first pointer exceedes to treat inverting event sets scope, goes to step e37, otherwise go to step e34 if exceed;
Step e34, calls alarm event interface driver by treating that inverting event reads in the alarm meter of inverting state, shows this event, and carry out phonic warning in alarm window;
Step e35, from historical dynamic data base, read the feeder line contact group profile data that the moment occurs this event, be loaded into the real-time storehouse of inverting state, in feeder line winding diagram or feeder line communication chart, show the power distribution network running status in this moment, fault section is carried out to corresponding location mark;
Step e36, next treats inverting event the first pointed, returns to step e33;
Step e37, the second pointer points to next according to actual conditions and treats the inverting event stage;
Step e38, judges whether to finish inverting, goes to step f, otherwise go to step e31 if finish.
9. the power distribution network accident overall process inversion method take feeder line contact group as unit according to claim 8, it is characterized in that, in described sequential inversion, described single step invertion or described process of pressing event procedure inverting, call SCADA history library interface driver event and enter history library, and Automatically invoked alarm demonstration and two existing functions of phonic warning.
10. the power distribution network accident overall process inversion method take feeder line contact group as unit according to claim 8, it is characterized in that, in described sequential inversion, described single step invertion or described process of pressing event procedure inverting, the multiple feeder line groups that break down are carried out to inverting one by one.
