Etude des émissions électromagnétiques CPL large-bande : caractérisation, modélisation et méthodes de mitigation

Abstract : With the growing demand for broadband applications and reliable connections for command and control systems, PLC technology is playing an increasingly important role in innovative systems such as communication networks and smart grids. The main advantage of this technology is its ability to benefit from the infrastructure of the existing power grid for transmission of electromagnetic signals. Currently, broadband systems mainly operate in the frequency range from 2 MHz to 30 MHz. However, in indoor environment of home or office the power supply electrical wires were not originally designed to convey communication signals at high frequencies. This thesis focuses on one of the main limitations to the indoor PLC technology, namely, unintentional radiation of electromagnetic signals. The first objective is to characterize the radiation level of a typical PLC system to check if it allows coexistence with other systems in the same environment. Then, the thesis evaluates and proposes methods to reduce the level of unwanted radiation.
