With the development of high rate data transmission technology via distribution line communication, the electric power, data, voice and video can be transferred in the same electric power distribution network, and the technology will be put in operation widely in the future. However the traditional technology of power line communication is not adaptable to the complex and harsh environment of distribution line channel. To achieve the task, this paper analyzes the nature of low voltage power line channel, explains the principle of Orthogonal Frequency Division Multiplexing, and introduces a practical communication system over PLC based on OFDM with hardware and software realization. Meanwhile, to improve the performance of the intelligent monitor system, the prediction system, based on data mining preparation and Least Squares Support Vector Machine, is presented for the short-term electric power consumption monitor system. In practice, the new intelligent system is highly reliable, economical, expendable, and works well.
