Standby supply district is counted, and so as to learn scope of power outage that each power failure plan is influenced, can carry out power failure meter
When drawing layout, the responsible consumer involved by power failure plan is analyzed, is obtained important involved by each power failure in the works
The information of user, in case the later stage can be avoided when scheduling optimization the double circuit feeding power supply to responsible consumer, all power failure is pacified
Row, ensures the electricity consumption reliability of responsible consumer.
The specific implementation for carrying out scheduled outage responsible consumer analysis can also be client's important level information according to storage,
Automatic screening and the different grades of Very Important Person for marking each power failure plan to be related to are related to power failure plan to realize
The screening of the responsible consumer arrived ensures the electric power thus supplied of responsible consumer.According to network topological information, the power failure to each plan that has a power failure
It amount and can turn to be analyzed for capacity, so that the later stage is when carrying out the optimization of power failure plan scheduling, can ensure each power failure plan
It disclosure satisfy that power reguirements, there is enough reliabilities.For example, can be in conjunction with the established network topology letter of automated system
Breath according to the looped network relationship of each circuit, circuit normal off point in distribution network and turns to turn for capacity situation for circuit, and analysis stops
Electricity in the works other than power failure line segment to the power supply line segment between circuit normal off point in automated system collected power load
Summation, if meet to close and turn for capacity requirement when normal off point turn power supply, statistics can not fully meet stopping of turning to supply
The power supply reliability situation of change of electricity plan carried out to ensure the power failure line that power failure plan is related to when scheduling optimization for the later stage
The reliability on road provides data foundation.Plan for each power failure, in conjunction with load prediction data, according to the influence amount that has a power failure, stops
Corresponding power failure load loss is planned in each power failures of statistics such as electric time, loss electricity, and reference is provided for the optimization of power failure plan scheduling
Information.

Loss load is analyzed.
In one of the embodiments, as shown in figure 4, planning to merging each power failure in the power failure plan set after adjusting
Carry out security reliability inspection, to do not meet preset condition power failure plan carry out safe early warning the step of include：
S141：It carries out protecting electrical conflict inspection to merging each power failure plan in the power failure plan set after adjusting, merge and stop
Electric responsible consumer inspection stops inspection and power failure marginal testing again；
S142：To protecting electrical conflict inspection, the inspection of merging power failure responsible consumer, stopping in inspection and power failure marginal testing again
Power failure plan of one or more inspection results beyond preset condition carries out early warning.
Wherein, preset condition is identical as the paraphrase in above-described embodiment, and this will not be repeated here.Specifically, after to merging
Power failure plan protect electrical conflict inspection, i.e., whether the dead line being related to each power failure plan has punching protecting between electric line
Whether the influence user of prominent or each power failure plan relates to protect electric user, if being related to protecting electric line or protecting electric user
When, whether execution time and its period of the protection of electricity for reexamining power failure plan limit and have overlapping, avoid the later stage from carrying out power failure plan scheduling excellent
When change, occur to protect electrical conflict.Responsible consumer inspection is carried out to the power failure plan after merging, i.e., scheduled outage responsible consumer is analyzed
Obtained responsible consumer information is compared with the user that power failure plan is related to, and checks that the power failure plan after merging whether there is
The case where responsible consumer, if there is then providing early warning, in case the power failure project impact arranged when later stage progress scheduling optimization is important
The power supply reliability of user.Check have a power failure number that the user that influences in the works has been had a power failure at the appointed time whether be more than
The permission frequency of power cut of user in the stipulated time being arranged in system configuration, if alreading exceed the frequency of power cut of permission,
Think to carry out power failure arrangement to the user again, when later stage scheduling optimizes, arranged power failure plan should avoid being related to
The user.It checks to have a power failure and plans whether amount when having a power failure total of set is more than that the maximum power failure allowed is gathered in the plan that has a power failure of setting
When amount, if amount is more than amount when setting maximum has a power failure when the plan set that has a power failure is total, then it is assumed that the power failure plan set pair
Power supply reliability influences greatly, and carrying out scheduling optimization for the later stage provides data foundation.
In one of the embodiments, as shown in figure 5, obtaining stopping for each power failure plan in power failure plan set to be optimized
The assessment result that film is rung, and each power failure is carried out as merging condition using the customer interrupted of overlapping and power failure line segment that is identical or intersecting

And；
S123：By recursive analysis, the scope of power outage of the power failure plan after merging is merged.
Specifically, checking all power failure plans, by power failure line segment and influencing user has completely overlapped power failure plan to merge
Together, a unified power failure plan is formed.There are juxtapositions by the power failure line segment that power failure plan is related to and influence user
Power failure plan merge, merging here refer to being related to establishing bundle relation between the power failure plan of juxtaposition,
It puts together when scheduling consideration, for example, can be arranged in, to reduce the power failure of cross section the same period on the same day
Number.Then, by recursive analysis, the scope of power outage of this group power failure plan is taken to having already passed through power failure plan after merging
Union then terminates when no any annexable situation.To reduce power failure plan that is completely overlapped or having juxtaposition
Involved in customer interrupted or the frequency of power cut that is undergone of dead line.
In one of the embodiments, as shown in fig. 6, the assessment result and safety that are influenced according to the power failure of each plan that has a power failure
