Research on the shortest path and multi-path transmission statistical model of PLC in smart grid

Smart grid represents the development direction of future power grid. Power line communication (PLC) technology plays a more and more key role in it. Due to the impedance discontinuous in PLC system, which causes multipath transmission and directly influences the quality of signal received, the property of multipath transmission is the critical factor to affect the performance of PLC system. Although there are many studies on multipath transmission, those studies are based on the analysis of specific situation information and features, which doesn't have good universality and consider the shortest path that has less reflection and attenuation. Combined with the shortest path, the paper analyzes and constructs the statistical model of PLC multipath transmission, without specific network analysis, which can offer reference for the design of PLC system.
