Data transmission over distribution power networks
Vašíček, Filip ; Mišurec, Jiří (referee) ; Zeman, Václav (advisor)
This thesis brings together information about the data transmission over distribution power networks with a view to the broadband systems. The division of PLC systems is mentioned and the principle and characteristics of PLC technology are described. I was also interested in topology and a description of elements of PLC network. There are presented the two most frequently used systems: HomePlug and DS2. Next section contains an analysis of network architecture, especially the physical layer. The protection of data against errors and the OFDM method are described. There are also analyzed other layers of the network reference model, the mechanism of quality of services and the data encryption using AES. I was also focused on the issues of standardization of PLC, the electromagnetic compatibility and a description of the international project OPERA. In the practical part is processed the concept of the laboratory PLC network with elements of the system Defidev/DS2. Functionality of the network has been tested by measuring of the bit rate on the physical and application layer.
