Step 4b, sort by priority dead electricity plant stand, ordering strategy comprises loss load, plant stand significance level etc., can manually modify to recovery order;
Step 4c, judge whether to lose power plant station, if not, recovered; If had, the dead electricity plant stand after cyclic ordering, adds up the dead electricity bus of plant stand respectively, circulates to the bus equipment in electric network model, obtain the bus in this plant stand, judges that whether this bus searches for the dead electricity equipment obtained in 4a;
Step 4d, to the dead electricity bus in this plant stand by electric pressure sequence, it is high that the high bus of electric pressure recovers priority;
Step 4e, search the standby electricity source point of this bus from bus equipment end points, this bus is set to root node, adopt BFS, search the connecting valve around this bus, if on off state is for dividing, judge the whether charged to side gusset of this switch, if charged, this switch is stand-by power supply electricity;
Step 4f, stand-by power supply point analysis: if standby electricity source point puts into operation, analyze this plant stand and whether lose goddess of lightning's line, if had, then get back to step 4e; If no, then this plant stand is successfully recovered, and obtains the recovery policy of this plant stand, gets back to step 4c, repeats said process, until all plant stands are recovered.
The invention has the beneficial effects as follows:
1) functionally to adopt and EMS system integration mentality of designing, shared electric network model, real time information, realize the non-maintaining of user of service.
2) distinguish traditional off-line accident recovery method, the present invention can generate accident recovery scheme online in conjunction with electrical network real time execution section, promotes the response speed of accident treatment.
3) traditional restoration methods is only confined to searching of supply path, the present invention is from user's practical operation, adopt layering to divide the restoration methods of plant stand, achieve the progressively recovery according to priority of power failure plant stand, what avoid that region-wide recovery causes turns the too high problem of power supply source load factor.
4) achieve the out-of-limit alignment technique adjusted based on mode, in fault, the rear out-of-limit equipment of rapid scanning can occur, provide and eliminate out-of-limit method optimizing scheme.
