Ethernet network connections are becoming more numerous in the domestic domain. In this work, the transmission on the power grid is preferred. This is the principle of powerline communication (PLC). This concept allows for transmission rates that can be higher Wifi transmissions. However, the performance can be degraded by environmental electrical and electromagnetic domestic housing. This thesis aims to model the electrical house environment and behavior of equipment that are deployed. Different types of noise present in the domestic environment were modeled to estimate their influence on the transmission quality CPL. Modeling of power lines was realised in the form of electrical circuits suitable for integration into simulation SPICE tools. The modeling of a two-wire cable has been extended to a three-conductor cable. The presence of electrical equipment has a significant impact on the PLC communication. This thesis presents two approaches to model the effects induced. The periodic and aperiodic impulsive noise is modeled to complete the analysis tool developed.
