A Real Time operation and Control of Devices using Power Line Communication

Abstract

In order to improve the ef?ciency and reliability of power delivery, Future Smart Grid systems will intelligently monitor and control energy ?ows. This monitoring and control requires highly reliable communication between customers, local utilities and regional utilities and also low-delay. A vital part of future Smart Grids is the two-way communication links between smart meters at the customer sites and a (decentralized) command and control center operated by the local utility. Narrowband power line communication (PLC) systems operating in the 3-500 kHz band are attractive to enable these two-way communication links because they can be deployed over existing outdoor power lines. However, Power lines, have traditionally been designed for unidirectional power delivery and remain hostile environments for communication signal propagation. In this article, with the use of PLC systems we review signal processing approaches to model channel impairments and impulsive noise and mitigate their effects in narrowband PLC systems. We will study the ways to improve the communication performance based on emerging standards and current.
