Grading power failure and restoration reporting method and system

Abstract

The invention discloses a grading power failure and restoration reporting method and system. The grading power failure and restoration reporting method includes the steps that S1. power failure and restoration events in a low-voltage distribution network are divided into three levels, and a priority level of each level is configured; S2. power failure and restoration monitoring modules are arranged in a station area, key monitoring points and each electric energy meter of the target low-voltage distribution network, whether the power failure and restoration events occur or not is monitored inreal time, and power failure and restoration signals are sent when the power failure and restoration events are monitored; and S3. according to the configured priority level order, whether the power failure and restoration signals are received or not is judged successively, and when the power failure and restoration signals are judged to be received, the corresponding level power failure and restoration events are generated for reporting, and current reporting ends. A device comprises a grading configuration module, a power failure monitoring module and a grading reporting module. The gradingpower failure and restoration reporting method and system have the advantages that the implement method is simple, reporting is timely and has high success rate, the power failure and restoration positions can be positioned conveniently, and repeat reporting can be avoided.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method and system for reporting power outages and restorations in different levels. Background technique [0002] For low-voltage power distribution network faults, power supply companies mainly rely on the power supply service command platform to handle faults, including the organization and scheduling of power outage emergency repairs and dispatch of work orders, etc. Pre-judgment is mainly based on calls made by users after a power outage, which may easily cause misjudgment of workload or recovery time for subsequent on-site processing, as well as low processing efficiency, high cost, 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-off events of low-voltage household meters, collectors, station mast...

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
