Development of Remote Monitoring and Control Device of 50KW Photovoltaic System

This paper deals with the efficient management for the intelligent distribution system related with the renewable energy sources, using the wire-wireless monitoring and control device. This device is mainly composed of 2 sections. One is monitoring device with the Autobase S/W and the other is control device using PLC. This paper proposes a wire and wireless monitoring and control device which can monitor and control the 50Kw PV system installed remotely (about 1Km) in the campus of the Korea University of Technology and Education. By the analysis of PV output characteristic using the device proposed in this paper, it is confirmed that the device can contribute the maintenance of PV system and also the establishment of Smart Grid.
