Abstract High construction cost blocks extensive application of networked power quality monitoring system (NPQMS), and the network scheme based on distribution line carrier communication (DLCC) is an effective strategy for problem-solving. For demonstrating the feasibility, content of the data needed to be uploaded and requirement of communication rate for each power quality monitor are analyzed detailedly. With an in-depth study on attenuation characteristics of DLCC channel, the properties of DLCC system based orthogonal frequency division multiplexing (OFDM) are analyzed and researched, such as communication rate and communication quality. Aiming at minimization of relay hops , an improved Dijkstra algorithm is proposed, which is used to optimize routing of the DLCC communication network. This research work will provide related theoretical basis and feasibility analysis result of the network scheme based on DLCC in NPQMS system.
