User voltage abnormality sensing method and system based on edge calculation

Abstract

The invention discloses a user voltage abnormality sensing method and system based on edge calculation, and relates to the field of electric power measurement. The method disclosed by the invention comprises: sensing the user power consumption condition by using metering automation terminals deployed in a distributed manner, reporting a terminal processing result to a master station system for processing, automatically judging, by the master station system when specific voltage data are collected according to the reporting result, and dynamically adjusting a collection task according to the communication capability to realize the quasi-real-time sensing of the user voltage abnormality condition. A user voltage abnormality sensing system based on edge calculation is established by using themethod disclosed by the invention, and by adopting the user voltage abnormality sensing method and system based on edge calculation disclosed by the invention, detailed voltage data of abnormal userscan be recorded and updated, and a graphical display interface is formed, thereby realizing the monitoring of a large number of users and facilitating the monitoring of abnormal data.

Description

technical field [0001] The present invention relates to the field of power metering, in particular to a method and system for detecting user voltage anomalies based on edge computing. Background technique [0002] With the rapid development of the economy, the power supply has gradually stabilized, and the existing focus has changed from the traditional "use of electricity" to the current demand for "good use of electricity" in every household. The people's requirements for electricity have gradually increased. Common electrical equipment has been widely used in vast rural areas, and the power distribution network built in the past to fully "use electricity" has been unable to support the existing electricity structure. Therefore, the problem of low voltage in urban-rural fringe areas, urban villages and rural areas is becoming more and more apparent. Power supply lines and transformers in many areas are overloaded and overloaded. [0003] The traditional solution is to use...

[0002] With the rapid development of the economy, the power supply has gradually stabilized, and the existing focus has changed from the traditional "use of electricity" to the current demand for "good use of electricity" in every household. The people's requirements for electricity have gradually increased. Common electrical equipment has been widely used in the vast rural areas, and the power distribution network built in the past to fully "use electricity" has been unable to support the existing power structure

Therefore, the problem of low voltage in urban-rural fringe areas, urban villages and rural areas is becoming more and more apparent. Power supply lines and transformers in many areas are overloaded and overloaded.

[0003] The traditional solution is to use a voltage monitor to collect the voltage of a small number of users in the station area in real time. The advantage of this is that the collection frequency is high and the real-time performance is strong; the disadvantage is that it can only be monitored for a few users in the station area, and cannot All users under the station area are monitored, with large gaps

Recently, with the wide application of AMI technology, it has gradually become a means to pay attention to the method of monitoring the voltage of the user through the electric energy meter and collecting the data to the main station for judgment, but this method is also greatly restricted by the conditions: (1 ) The communication bandwidth from the energy meter to the concentrator limits the frequency of voltage collection by the energy meter; (2) The centralized management of the collected data brings a lot of waste of storage resources; (3) The concentrator is performing a large number of voltage collection tasks At the same time, it will occupy the processing resources of the normal energy collection of the energy meter
