Abstract

Power line communications can be utilized to build up the data transmission network wherever the electricity is available. This type of communication system could provide a basis for the network construction in many application areas which include the smart grid and home networks. On the other hand the power line communication is vulnerable to various types of interferences and noises. Also, its channel characteristics are constantly changing depending on the type and the amount of electrical loads connected to the network. Especially, the usage of DC power supply has been increased due to the explosive expansion of smart devices in our daily lives which result in the increased level of interferences on the power line channel. In this paper, the effect of the operation of the DC power supplies on the channel characteristics and the data transmission performance is analyzed through the experiments.

전력선 통신은 전기를 사용할 수 있는 어느 곳에서든지 데이터 전송 네트워크를 구축하기 위해 사용할 수 있다. 이러한 종류의 통신 시스템은 스마트 그리드와 홈 네트워크를 포함한 다양한 적용 분야에서 네트워크 구축을 위한 기반으로 제공된다. 반면에 전력선 통신은 다양한 종류의 간섭과 잡음에 취약하다. 또한 네트워크에 연결된 전기적 부하의 양과 종류에 따라 전력선 통신 채널의 특성이 지속적으로 변화한다. 특히 일상생활에서 스마트 기기의 폭발적인 증가에 의한 직류전원 공급장치의 사용이 증가함에 따라 전력선 통신 채널의 간섭 영향이 증가한다. 본 논문에서는 실험을 통하여 직류전원 공급장치의 동작에 따른 전력선 통신 채널의 영향과 데이터 전송 성능을 분석한다.
