The distribution power line carrier system has been used for an automatic distribution control, in order to advance the highly reliable operation and labor saving on electric power supply in suburban districts. In this system, harmonics noise becomes a serious problem deteriorating the data communication performance.
This paper proposes a method in which the high speed data communication can be realized under harmonics noise by using DPSK (Differential Phase Shift Keying) and a comb filter. First, the performance of the system was computer-simulated using harmonics noise gathered from in-service power lines. Then, the capability of the system transmission rate to get at 120 bits per second (bps) was confirmed in the field experiment.
