Problems solved by technology

However, since the power meter according to the prior art can only display the accumulated electric energy in one direction, there is a need for a power meter capable of displaying the instantaneous energy consumption in real time, and displaying the electric energy accumulated in both directions of power transmission and power reception, and between power transmission and power reception. Different Power Meters Used in Power Reception
Correspondingly, since multiple power meters are used to measure the transmitted power and received power respectively, disputes may arise when calculating the transmitted power and received power due to the errors of these power meters, and since these power meters are installed separately Yes, it also creates some problems when operating the power system

Abstract

The present invention relates to a bi-directional digital power meter, and more particularly, to a bi-directional digital power meter capable of measuring bi-directional data of transmission power and reception power, correcting each error, displaying the difference between the transmission power and reception power in real time, and outputting the difference to external communication means, thus efficiently managing power in connection to a smart grid system.

Description

technical field [0001] The present invention relates to a two-way digital power meter, and more particularly, to a two-way digital power meter that can display instantaneous energy consumption in real time, as well as accumulated electric energy in two directions of power transmission and power reception, and according to each operation The characteristics of the environment, perform specific error correction. Background technique [0002] Utilities maintain a balance between demand and supply of ever-changing electricity consumption (i.e., transmission and generation). Electric companies, for example, receive electricity from other electric companies in some cases in order to maintain a balance between demand and supply. As the load increases, if the amount of electricity delivered increases significantly, then there is no balance between transmission and generation, and the power company needs to receive power from other power companies to make up for the power shortage. ...
