A hierarchical intelligent research and judgment method and device for power outage and restoration events in a station area

Abstract

The invention discloses a method and device for intelligently judging the level of power failure and restoration events in a station area. The method steps include: S1. Real-time monitoring of power failure alarm events in the station area, when monitoring an alarm event uploaded by a station area-level terminal, transfer to Step S2, when monitoring the alarm event uploaded by the meter, go to step S3; S2. According to the level, judge whether the power failure occurs in the station-level terminal and the station area in turn, and control the corresponding meter to mark the power failure unit; S3. According to the station area In the state of power failure of the level terminal, the control judges whether there is a power failure in the meter, the terminal to which the meter belongs, the station-level terminal, and the station area, or judges the meter, the terminal to which the meter belongs, the station-level terminal, and the station according to the level. Check whether the power failure occurs in the meter box and branch line in the district, and control the corresponding meter to mark the power failure unit. The invention has the advantages of simple implementation method, intelligent research and judgment of power failure and restoration in the station area, and high research and judgment efficiency and precision.

Description

technical field [0001] The invention relates to the technical field of low-voltage distribution network monitoring, and in particular to a method and device for hierarchically intelligent research and judgment of power outage and restoration events in a station area. Background technique [0002] There are a large number of metering and collection equipment terminals, electric energy meters, and collectors in the low-voltage distribution network station area. Data collection terminals, etc. 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. Different application scenarios may use different data acquisition methods, such as data communication between the master station and the terminal using the wireless public network, data communication between the terminal and the energy meter using RS485 or low-voltage power line carrier / micro-power wireless, the c...

[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
