Application Of Power Line Carrier Communication Technology In Electrity Information Acquisitions System

With the launching of the national smart grid construction, the construction of the information collection system is also in full swing. Power line carrier communication technology has the unparalleled advantage of the convenient, maintenance-free reliability, economy, plug and play, get a wide range of applications in the information collection system, in particular, FSK, PSK, OFDM modulation mode carrier communication technology has been widely used.. However, with the popularity of the power line carrier communication technology, performance evaluation of different carrier communication technology, the future direction of the power line carrier communication technology has also become the focus of attention.This paper briefly introduces the concept of smart grid, the relevant principles of the power line carrier communication technology and the information collection system in a typical application.. Summarize and analyze the carrier vendors and carrier solutions of the currently widely used in the domestic electricity market, to study the technical features of each carrier and each carrier program evaluation, in a typical system architecture to explore the advantages and disadvantages of different carrier technology. And then, the hot spots of domestic and international power line carrier communication technology to track the application of OFDM-based RRIME program introduced in Europe began to explore the future direction of the power line carrier communication technology.
