초록

본 논문은 국내 지중 저압선에 대한 협대역 PLC 기술의 통신 채널 특성과 이를 기반으로 한 적용성 연구결과에 대해 기술한다. 지중 저압선이 매설된 실제 거주지역에 협대역 PLC 채널 측정을 위한 시스템을 구성하였으며, 이를 통해 채널 응답, 잡음 PSD, 선 임피던스를 포함하는 채널 특성을 측정하였다. 측정된 채널 특성을 분석하여 국내 지중 저압선의 채널 특성이 협대역 PLC 적용에 적합한 특성을 띠며, 250kHz 이후 주파수 대역이 특히 양호한 특성을 나타내는 것을 보였다. 이를 기반으로 IEEE P1901.2 규격을 채택, FCC High 대역을 이용하여 네트워크 테스트를 수행하였으며 이를 통해 국내 지중 저압선에 협대역 PLC 기술의 적용이 가능함을 확인하였다.

This paper presents in details channel and noise characteristics over narrow bands below 500kHz based on the field tests over underground low voltage(LV) power lines in residential areas in Korean grid. We show that the channel characteristics of narrowband signals over underground LV power line are decent. We first describe methodology of channel characteristic measurements including channel frequency response, noise, and line impedance, and obtain channel characteristics over the underground LV lines in the residential areas. Also based on the measurement results, we adopt the IEEE P1901.2 standard on the FCC High band, and bring up narrow band power line communication network.
