Power line communication (PLC) is a communications method where signals are carried across already existing power lines, rather than through other mediums such as optical fibers or radio waves. PLC has been a very important interdiscipline topic for power, communications, industrial, and automation engineers and researchers since the 1980s. Designing and planning optimized or standard PLC systems require information and data regarding signal attenuations, load variations, and communication performance for various locations of the world which have different power networks. In this study, PLC system is modeled by ABCD matrix and simulated via electronics workbench. In order to obtain data from Turkey's power lines, signal measurements at the frequencies of 50-200 kHz are carried out. The effects of load, frequency, line length, and the distribution transformers are examined. The properties of home appliances used in an average Turkish household are experimentally determined. System performance in terms of the bit error probability are calculated for FSK modulation.
