Abstract
Whether the energy metering device is accurate or not is related to the economic interests of both the division and sale of electric power, but in reality, energy metering device failure is inevitable. When a failure occurs, it must be certain of the correct way to calculate the accrued power. Classic methods of electricity are estimated by returning and adding “correction coefficient”, but the fault characteristics of electronic table differs from previous induction meter. Electrical parameters and the cumulative power is erratic, leading to “correction coefficient method” failure. This paper describes a means of electrical parameter automation metering systems continuously recorded using the thought of “integration”, the correction coefficient to compensate for the lack of power to solve real projections fault electronic energy meter problem.

Summary
With good technical advantages in terms of energy metering, automated metering system has been promoted and applicated in Power Supply Bureau. As a subsystem of automated metering system of the substation measurement, plant metering station automation system automating the collection, processing, storage providing data for line loss statistics and analysis for assessment, and passing electrical energy information, it can carry on real-time monitoring of the entire network effect measuring device. A detailed record of the measurement event of a fault meter for measurement management can query the point of failure, the observed fault changes and cause analysis was provided. The use of automated metering system, combined with thought of "integration" of the metering device during the power failure, has a greater advantage than conventional projection correction coefficient method. Through a typical case study, this paper introduces an application process integration method [1]
