In order to further consolidate the management level of power supply reliability, early warning and management of major outage events that may occur are required.
The traditional major outage event early warning is that a dispatcher manually and comprehensively studies and judges whether the early warning needs to be issued according to line information, the number of users affected by the line and the power failure time.
The traditional major outage event early warning process comprises the following steps:
1. the equipment part writes a annual major fault power failure event line list; 2. the customer service center service shifts to provide the number of medium-voltage and low-voltage users influenced by tripping and grounding lines; and finally, comprehensively distributing network line tripping information, equipment part line list and service shift influence user number by a distributing network dispatcher to confirm whether the early warning short message needs to be issued. Not only is the efficiency low but also the accuracy is not guaranteed.
2. The distribution network dispatcher can not follow up the outage time of the fault or maintenance equipment to confirm whether to send the early warning short message or not because the distribution network equipment is more in jurisdiction and more in daily operation, especially when the distribution network equipment is in large-area power failure due to bad weather, the distribution network dispatcher can hardly extract time to issue important power failure event early warning because of busy accident handling, the omission of early warning issue can lead to incomplete management and control, and the failure of management and control is very likely to lead to a large power failure event.

step S33: judging whether the power failure time in the distribution network tripping information exceeds 5 hours, if not, not sending a short message, if yes, judging whether the power restoration time in the distribution network tripping information is backfilled, if not, not sending the short message, if not, popping up a message box to remind a dispatcher to backfill the power restoration time, and if the dispatcher still does not backfill the power restoration time after 30 minutes, sending a short message of 'major power failure event early warning B' to a mobile phone of a group personnel which is maintained in advance; if the dispatcher backfills the duplicate time within 30 minutes, a short message is not sent;
step S34: judging whether the power failure time in the distribution network maintenance list information related to the power failure of the user exceeds 10 hours, if not, not sending a short message, if yes, judging whether the power restoration operation ending time in the distribution network maintenance list information related to the power failure of the user is backfilled, if backfilled, not sending the short message, if not, popping up a message box to remind a dispatcher to backfill the power restoration operation ending time, and if 30 minutes later, the dispatcher still does not backfill the power restoration operation ending time, sending a short message of 'major power failure event early warning C' to a mobile phone of a group person which is maintained in advance; if the dispatcher backfills the end time of the duplicate operation within 30 minutes, a short message is not sent;
step S35: and visually displaying distribution network maintenance list information and short message sending conditions related to user power failure, distribution network tripping information and short message sending conditions.
