Research on Channel Modeling and Topology Performance Analysis of PLC Network

At present, the existing research on power line communication only focuses on simple networking forms, such as bus networks. Most importantly, it lacks theoretical analysis and networking suggestions for complex communication network channel characteristics. In view of the above problems, based on the two-port network channel model of transmission line, this paper proposes tree and star networking forms based on the known bus network topology, and establishes the mathematical model of its channel. Finally, the channel characteristics of the three topologies in different scenarios such as transmission distance, node distribution and branch number are simulated and analyzed. After research, the star topology has better channel characteristics. This paper puts forward relevant suggestions for power line communication networking, which has certain guiding significance for the actual deployment of power line communi-cation network.
