Gateway electric energy metering device on-line monitoring method and system of shunt routing inspection

Abstract

The invention relates to a gateway electric energy metering device on-line monitoring method and system of shunt routing inspection. The gateway electric energy metering device on-line monitoring method of shunt routing inspection comprises the steps that an on-line monitoring main machine shunt collects monitoring data of electric energy metering devices of various metering loops; the monitoringdata are stored in an array mode; the stored monitoring data are calculated; a calculation result is stored in an array mode; the monitoring data and the calculating result are analyzed, if it is analyzed that abnormal condition exists, fault warning is carried out on the abnormal condition, and real-time on-line monitoring is carried out on the metering loops with faults occurring; and if the abnormal condition does not exist, the steps are repeated, and routing inspection is carried out on the metering loops. According to the gateway electric energy metering device on-line monitoring methodof shunt routing inspection, real-time on-line monitoring is carried out on electric energy metering device, many monitoring points are achieved, the monitoring range is wide, functions are complete,fault analysis is comprehensive, and the gateway electric energy metering device can be effectively ensured to normally operate.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of gate metering devices, and in particular relates to an on-line monitoring method of a gate electric energy metering device for branch patrol inspection and an on-line monitoring system for a gate electric energy metering device for branch patrol inspection. Background technique [0002] Monitoring requirements usually require that the more accurate the monitoring results and the higher the real-time performance, the better without affecting the normal operation of the equipment on the metering system. At the same time, it is necessary to support more monitoring points and a larger monitoring range. However, the current gateway electric energy metering devices mainly include voltage transformers, current transformers, secondary circuit cables and electric energy meters. These devices have errors and various failures may occur. The traditional management methods are regular inspections ...
