This paper introduces a new MV powerline communication device （PLC-075） and its application in managing mediumsmall hydropower plants running in connection with grid and distribution automation system in a Shanghai urban area. It shows that the device can meet the needs of hierachical and real-time control in its application by using multiple logic communication networks based on virtual carrier sense mechanism, enhanced adaptive analog front end of receiver, adaptive frequency bands and coupling means etc. A aerial successful experiments indicate that the device can adapt to the change of the MV distribution line＇s transport characteristic, and that it can be used as a low-cost communication alternative in many application fields.
