A new power line communication modem design with applications to vast solar farm management

This paper presents a new power line communication (PLC) modem design which can control data flow with a new networking strategy to propagate signals for long distance without using extra cabling or signal repeaters. An investigation is also carried on the utilization of twin core power line cables in vast solar farm for controlling solar trackers and data acquisition purposes. Frequency responses of these power lines are analyzed and tested according to different coupling circuits. A simple design is proposed for PLC modem based on such channel characteristics, data flow control strategy, collision avoidance technique and error detection.
