Development of Communication Protocol and Data Structure of Electronic Power Meter for Automatic Reading System

摘要

With the development of Computer & Communication Technology, nowadays many people are interested in remote metering, and a lot of vendors are suggesting various remote metering solutions. KEPCO (Korea Electric Power Corporation) adopts some of these for some customers who use a lot of electric power, and continues researching them. But, currently exploited electric power meters vary in the view of communication protocol and data structure by the vendors. So we have to know each vendor's communication protocol and data structure to construct a remote metering system, or to find problems in it. But that's impossible to know each vendor's protocol and data structure because they are reluctant to tell those to outside the company. To solve these problems and to make a much more cost-effective metering system, KEPCO developed standard communication protocol between meters and PC (or metering server), and defined access method and data structure for the meter which can be used by everyone easily. Those developments support standard interface for every vendors' meters. And Those will be adopted by KEPCO for a part of new metering standard for electric power meters.
