Modélisation de la propagation des signaux HF dans un réseau d'énergie électrique

Abstract : This thesis concerns the study of the propagation of the signal of power line communication (PLC) in the distribution power network. In order to simulate the phenomena, the HF models of the elements were elaborated, mainly for transformer MV/LV. main part is consisted in the HF identification of the MV/LV transformer of power, major and complex element of the distribution network. After a bibliographical study of the models of the HF transformer, we carried out many external measurements on two real transformers 20/0.4kV of medium power in order to obtain their impedances of transfer in the range 100Hz - 10MHz. Equivalent circuits were proposed, one in MF and another in HF. Measurements and the necessary methods to determine the characteristics of transfer of signals MF-HF through the transformer were synthesized and presented. In order to validate these models, the characteristics of transfer of signals through the transformer are measured and then compared with simulations. Then, the models HF of the other principal elements met in the distribution network are analyzed. Finally, we implemented the models to simulate with ATP/EMTP the propagation of the signals HF in a real distribution network. Several diagrams are exploited in order to find out the topological parameters, which influence the quality of transmission of the PLC.
