A hardware system based on digital signal processor (DSP) is designed for power line carrier communication (PLC) over medium voltage power line networks. This system is designed to realize better stability and reliability of data communication in electric system. This paper introduces PLC technology, and then discusses the composition of this system and gives design scheme. Finally, the DSP implementation is developed with analog front-end (AFE) and coupling circuit. This paper shows a new PLC and automatic management solution.
