A hierarchical method and system for reporting power outages and restorations

Abstract

The invention discloses a method and system for reporting power outage and restoration by grade. The steps of the method include: S1. Dividing power outage and restoration events in a low-voltage distribution network into three levels of power outage and restoration events, and configuring the priority levels of power outage and restoration events at each level ; S2. Arrange outage and recovery monitoring modules in the target low-voltage distribution network’s station areas, key monitoring points, and energy meters to monitor in real time whether a power outage and recovery event occurs and send a power outage and recovery event when a power outage and recovery event is detected. Signal; S3. Judging whether to receive the power outage and recovery signal in turn according to the priority order of the configuration, when it is judged that the power outage and recovery signal is received, generate a corresponding level of power outage and recovery event to report and end the current report; the device includes hierarchical configuration module, power outage monitoring module and hierarchical reporting module. The invention has the advantages of simple implementation method, timely reporting, high success rate, convenient location of the location of power failure and recovery, avoiding repeated reporting, and the like.

Description

technical field [0001] The invention relates to the technical field of power systems, and in particular, to a method and system for reporting power failure and resumption of power at different levels. Background technique [0002] For low-voltage power distribution network faults, power supply companies mainly rely on the power supply service command platform for fault handling, including the organization and dispatch of power outage repairs and work order distribution. It is mainly based on the calls made by users after a power outage to make predictions, which may cause misjudgment of workload or recovery time for subsequent on-site processing, as well as low processing efficiency, high costs, and many potential safety hazards. The power consumption information collection system is connected with the power supply service command platform, and the power consumption information collection system pushes the power failure event of the low-voltage household meter, collector, st...

Problems solved by technology

[0004] At present, the reporting of related events of electric energy meters is based on the use of the running status word to report the previous power-off and power-on events in the live state, that is, the running state of the electric energy meter determines the report of the power-off event, and various terminals and collectors in the distribution network Power outage and recovery events may occur, that is, not only including energy meter events, but also collector events and terminal events. When a power outage and recovery event occurs, it may be a single device event such as a single energy meter, a single collector or a single terminal, or may It is a multi-device event of multiple devices such as multiple energy meters, multiple collectors, or multiple terminals, and it may also be a full-device event of all energy meters, all collectors, or all terminals. The reporting method cannot distinguish energy meters, collectors, and terminal events, and cannot accurately locate the location of the power outage and restoration event. In fact, different locations and different ranges of power outage and restoration events have different impacts, such as terminal events such as concentrators. When it occurs, if it is not dealt with in time, it will have a great impact on production, life and personal safety.

[0005] Some practitioners proposed to set up power outage and recovery monitoring equipment in the concentrators, collectors and other equipment in the distribution network except for the electric energy meter. Power recovery events can be reported to the master station when power failure and power recovery events occur in energy meters, concentrators, collectors and other equipment, but there will be a large number of repeated reporting situations in this type of method. Concentrators, energy meters, collectors and other equipment will monitor and report power outages, and the bandwidth of the communication channel is limited. When a large number of nodes report events at the same time, there will inevitably be cases where reported events are lost, resulting in event reporting failures, and It is not conducive to locating the location of the power outage and restoration event, and cannot deal with the power outage event in time
