Design of Smart Feeder Terminal Unit Based on Power Line Carrier
Smart distribution network automation relies on advanced communication.Power line carrier (PLC) becomes the first choice of the power grid with complex geographical distribution owing to its superiority in fully using the power line as a communication medium,high reliability and low cost.Based on a new type of low-frequency narrow-band power line carrier communication,a distribution network feeder terminal unit (FTU) was developed.This paper analyzed the hardware and software technologies of FTU,emphatically the core module of power line carrier communication,and achieved remote access between the power line carrier and FTU on PC program.Two experimental results of simple command transfer and large file transfer through power line carrier show that the FTU controller developed based on PLC can keep stable performance and high data rate in high-noise electricity environment.
