Progress in the research of narrow-band power line carrier communication and it's limitations are intro-duced in the paper. Signal relay strategy in the link layer is an effective method to expanding the valid communica-tion length and reliability. The physical and logical models of narrow-band power line communication of lower-volt-age distribution are presented. An appointed relay strategy is provided firstly. Then, the pure traversal searching al-gorithm based on graph theory for networking is presented and discussed account for the limitations of artificial ap- pointed relay. Time complexity and communication complexity are also analyzed in the paper. The theory analysis and testing in the lab indicate that this method can realize the automatic relay in the power line communication sys-tem, and it also provide a reference method for engineering using.
