A Study on the Power Control System for Electric Machineries using Power Line Communication
전력선 반송통신을 이용한 전기기기 전원 제어 시스템에 관한 연구
Abstract
Recently, a lot of studies on the power line communication(PLC) are being done by many companies and institutes due to its own merit which can use the power line spread widely as a communication channel. But, there are many serious problems about the harsh and unpredictable characteristics, or noise, signal distortion and attenuation to be overcome for commercialization. In this paper, the power line characteristics as the view point of communication channel are investigated and the technologies of PLC are proposed to control the power of electric machineries by using the combined method of ASK modulation and microprocessor technologies. Also experiments are carried out to ascertain performance in case of applying to electric lights control according to various distancea as an example.
