AMR field trial on underground power distribution line using BPLC

This paper is concerned with the result of AMR (Automatic Meter Reading) test field experiment, which was constructed by using power lines from MV (Medium Voltage) and LV (Low Voltage) test fields of underground power distribution line. 75 households from 7 multiplex houses in Ansan-si Choji-dong were selected as objects of study, and the test field was constructed in which the power usage could be observed in real time, and the possibility of constructing a network using BPLC in both the MV and LV test fields of the underground power distribution line was verified. In the underground MV test field, the network is constructed using a BPLC (Broad PLC) repeater and a neutral inductive coupler, and in the underground LV test field, the network is constructed using a BPLC modem and three phase capacitor couplers. The places in the MV and LV test fields where the BPLC modem is installed are composed so that the power usage can be observed in real time, by using AMR server program. This paper shows that AMR using BPLC is possible in the underground power distribution line, and shows that PLC can play an important role in the construction of AMR system in the future.
