| Abstract: | This paper describes the power line carrier(PLC) broadband remote-control communication system based on orthogonal frequency division multiplexing(OFDM).It is indicated that data communication rate exceeding 1 Mbps can be achieved by applying OFDM to 10 kV distribution PLC communication,thus meeting the stringent reliability requirement on broadband telecontrol communication in MV distribution network.The key techniques of the system are analyzed.Compared with conventional PLC communication technology,it can provide higher spectrum utilization ratio,quicker communication rate,better capability against channel deterioration and higher reliability. |
| Keywords: | orthogonal frequency division multiplexing(OFDM) power line carrier(PLC) communication distribution automation telecontrol communication system |
