Method and device for intelligently judging level of power outage and restore events in station area

Abstract

The invention discloses a method and device for intelligently judging a level of power outage and restore events in a station area, and the method comprises the following steps of S1, monitoring power outage alarm events in the station area in real time, proceeding to step S2 when an alarm event uploaded by the station area-level terminal is detected, and proceeding to step S3 when an alarm event uploaded by a meter is detected; S2, determining whether there are power outages in the station area-level terminal and the station area according to the level, and controlling the corresponding meter to mark the power outage units; and S3, determining whether there are power outages in the meter, the meter-belonging terminal, the station area-level terminal and the station area based on the level according to the state of power outage at the station area-level terminal, or determining whether there are power outages in the meter, the meter-belonging terminal, the station area-level terminal, the meter box in the station area and branch lines based on the level, and controlling the corresponding meter to mark the power outage units. The method provided by the invention has the advantages that the implementation method is simple, the intelligent judgment of the power outage and restore of the station area can be realized, the efficiency and precision of the judgment are high, and the like.

Description

Technical field [0001] The invention relates to the technical field of low-voltage power distribution network monitoring, in particular to a method and device for intelligently studying and judging a power outage and resumption event in a station area. Background technique [0002] There are a large number of metering collection equipment terminals, electric energy meters, and collectors in the low-voltage distribution network station area. The metering collection equipment terminals include type I concentrators, type II concentrators, distribution transformer monitoring and metering terminals, load management terminals, and station electrical energy Data acquisition terminals, etc. The electric energy meters are divided into three-phase electric energy meters and single-phase electric energy meters. Collectors include type I collectors and type II collectors. Between the master station and the terminal, and between the terminal and the electric energy meter and the collector, fol...

Problems solved by technology

[0003] When a power outage and recovery event occurs in the equipment in the station area, a power outage and recovery alarm event will be generated and sent to the master station. Currently, the report of related events of the electric energy meter is based on the report of the previous power outage and power on event using the running status word in the live state, that is, by The running status of the electric energy meter is used to determine the power outage and recovery event and report it. After receiving the power outage and recovery alarm event, the master station verifies the power outage and recovery status at the location where the event is reported, but it can only clarify the power outage and recovery status at the location where the event is reported. Power outage and recovery status in other locations and the specific area where power outage and recovery occur, and power outage and recovery events may occur in various terminals and collectors in the distribution network, which includes not only 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 it may be a multi-device event such as multiple energy meters, multiple collectors or multiple terminals. It may also be all equipment events of all electric energy meters, all collectors, or all terminals. Different locations and different ranges of power outage and restoration events have different impacts. For example, when terminal events such as concentrators occur, if they are not handled in time Great impact on production, life and personal safety

[0004] When the main station receives a power outage and recovery alarm event, if it is necessary to specify the specific power outage and recovery location at the same time, it usually obtains all the equipment within a certain range of the report location of the power outage and recovery alarm event in the station area to judge. The method requires a large amount of data acquisition and judgment processing, the execution efficiency is low, and it is difficult to quickly interpret the location and area where the power outage and restoration occurred
