Automatic time synchronization method and time synchronization system for electric energy meter metering device based on RPA

Abstract

The invention discloses an automatic time synchronization method and system for an electric energy meter metering device based on RPA. The method comprises the steps that S1, a list of all electric energy meter metering device users in a transformer area is obtained; s2, selecting low-voltage users in the user list, and putting screened low-voltage user packets into a time synchronization list; s3, interrogation time synchronization is carried out on the electric energy meter clock of the user in the time synchronization list, and an electric energy meter clock error of the current user is obtained; if the user clock error is within a preset error threshold value, time synchronization succeeds, if the user clock error is outside the preset error threshold value, time synchronization fails, user information corresponding to the electric energy meter with successful time synchronization is written into the Excel electric energy meter with successful time synchronization, and user information corresponding to the electric energy meter with failed time synchronization is written into the Excel electric energy meter with failed time synchronization; s4, all users in the time synchronization list in the transformer area are traversed, a final report is generated, and the final report comprises the time synchronization success Excel electric energy meter and the time synchronization failure Excel electric energy meter. The system is convenient to operate, high in time synchronization efficiency and accurate and stable in process execution.

Description

technical field [0001] The invention relates to the field of time calibration of electric energy meter measuring devices, in particular to an automatic time calibration method and time calibration system of an electric energy meter measurement device based on RPA. Background technique [0002] Dipu Power Supply Station currently has 1,033 public transformer stations and more than 94,000 low-voltage users. Daily planned power outages and high-voltage faults will cause power outages in the relevant station areas, which may easily lead to battery undervoltage in the station area. Abnormal, resulting in the failure of customer meter data collection, which in turn affects the acquisition success rate of the station area and the line loss index of the station area. This situation is relatively common in the urban area of ​​Anji. Therefore, the clock synchronization of the customer's meter has become one of the key ways to control the acquisition success rate of the station area an...
