The purpose of the thesis is the examination conducted disturbances that can be found in the low voltage electrical network regarding to PLC communications. After the smartmetering overview I examen the smart grid.
I summerize briefly the disturbances in the 2 - 150kHz frequency range, investigate the main sources for them with the help of ITU -T documents.
I developed measuring setup to measure and process the data for conducted disturbances.I developed batch matlab processes, so that measurements can be analyzed rapidly. I made measurements o the low-voltage networks. In order to get the highest accuracy I went on to measureme on a number of different locations. The
majority of the test equipment can be easily found in households. I compare the results with the initial expectations .
It turned out that the investigation of disturbances requires interdisciplinary knowledge. The PLC technology despite of its critics provides a real opportunity in case
of network wide smart meter implementation, if network analysis predates rollout.
