Abstract

The invention discloses a metering abnormality online monitoring method and system and a readable storage medium, and relates to the field of metering abnormality monitoring. The method comprises thefollowing steps of collecting electric energy meter frozen data and real-time data according to an acquisition frequency, and processing the collected data in real time, wherein abnormal parameters are calculated according to the collected data, wherein the abnormal parameters comprise a voltage imbalance parameter, an electric energy meter online state estimation parameter and a current imbalanceparameter; whether the abnormal parameters exceed a set threshold or not is judged, and if the abnormal parameters exceed the set threshold, reminding is triggered and then continue collection is performed; or otherwise, after the abnormal parameters are saved, and then the collection is continued. The automatic and efficient lookup of the metering abnormality is realized and the metering abnormality judgment accuracy is improved by carrying out in-time analysis on the abnormal parameters, and by newly adding the calculation voltage imbalance parameter, the electric energy meter online stateestimation parameter and the current imbalance parameter, so that the abnormal processing efficiency is improved, and the problem of low abnormal discovery and processing efficiency in the existing manual metering abnormality troubleshooting is solved.

Description

technical field [0001] The invention relates to the field of measurement abnormality monitoring, in particular to an online monitoring method, system and readable storage medium for measurement abnormality. Background technique [0002] With the large-scale promotion of smart energy meters and the gradual popularization of smart terminals, the number of running smart meters has been increasing year by year, and the growth rate of the number of dedicated variable users has repeatedly hit new highs. The use of a large number of smart energy meters also means a lot of daily operation and maintenance management. [0003] Due to the variety of user load characteristics and the different operating environment characteristics of various types of electric energy meters, it is necessary to formulate a dedicated monitoring plan for smart electric energy meters. [0004] Under the existing working mode, when faced with meter failures, the metering staff of grass-roots power supply comp...
